An Analysis of "On Certainty"

Sam26 May 31, 2020 at 12:57 22000 views 985 comments
On Certainty is a response to Moore's papers, Proof of an External World and A Defense of Common Sense in which Moore proposes a number of propositions that he claims to know with certainty. Propositions such as the following: "Here is one hand" and "There exists at present a living human body, which is my body (G.E. Moore, Philosophical Papers (1959), p. 1)." Moore continues to enumerate other propositions that he claims to know, with certainty, to be true. These propositions provide for Moore a proof of the external world, and as such, they supposedly form a buttress against the skeptic.

As we shall see as we examine On Certainty it is not only Moore's claim to knowledge that Wittgenstein criticizes, but he also critiques the skeptic, and specifically their use of the word doubt. Wittgenstein's response to Moore's propositions is not entirely unsympathetic, although he argues that Moore's propositions do not accomplish what Moore thinks they do, namely, to provide a proof of the external world. Moore's proof is supposed to undermine the doubts of the skeptic. It is also supposed to demonstrate that the conclusion follows necessarily, and if it does, then the skeptic's doubts are supposed to vanish - at least in theory. The proof would look something like the following:


1) Moore has knowledge that he has two hands.
2) Moore infers from the fact that he has two hands, to the conclusion that
there exists an external world.
3) Hence, Moore knows that an external world exists.


Wittgenstein is challenging the first premise in the above argument; more specifically, he is challenging Moore's claim that he has knowledge of his hands. Having knowledge of something presupposes that there are good reasons (at least in many cases) to believe it, but exactly what is it that Moore has knowledge of? He claims to have knowledge of the existence of his hands, but what would count as evidence for such a claim? Do I know that I have hands because I check to see if they are there every morning? Do I make a study of my hands, and thereby conclude that I do indeed have hands? I have knowledge of chemistry, physics, history, epistemology, and other subjects, and there are ways to confirm my knowledge. However, in our everyday lives do we need to confirm that we have hands? And do we normally doubt such things?

From here I will examine On Certainty, sometimes line-by-line, other times a section at a time.

I've done this analysis before, but I'm re-writing it to update it. Hopefully, this analysis will be better than the original. I'm not sure how far I'll get, but I'll give it a go.

On Certainty Post #2

"If you do know that here is one hand [G.E. Moore, Proof of an External World], we'll grant you all the rest. When one says that such and such a proposition can't be proved, of course that does not mean that it can't be derived from other propositions; any proposition can be derived from other ones. But they may be no more certain than it is itself (OC, 1)."

So, Wittgenstein grants that if Moore does indeed know that he has a hand, then Moore's conclusion follows (see post 1). The skeptic says that such a proposition can't be proved. This doesn't mean, according to Wittgenstein, that we can't derive them based on other propositions. However, the derivation may not be any stronger than the proposition we started with. My interpretation is that there is something foundational here, viz., that some propositions are foundational to our claims of knowledge or our claims of doubt. When you reach bedrock no part of the foundational structure is stronger.

"From it seeming to me--or to everyone--to be so, it doesn't follow that it is so. What we can ask is whether it can make sense to doubt it (OC, 2)."

The skeptic may have a point (although it may not be the point he/she is trying to make), that just because people (or Moore) say something is so, it doesn't follow that it is. However, Wittgenstein points out that what we need to ask, is whether the doubt makes sense. Doubting occurs in a language-game, and language-games have rules - later Wittgenstein will point out that a doubt that doubts everything is not a doubt. Some kinds of doubting make no sense, i.e., if you start out doubting everything, then doubting loses all sense.

Knowledge has to be demonstrated - whereas Moore seems to just state his propositions as facts, and this needs to be shown or demonstrated in some way.

The word certainty in On Certainty seems to be used in at least two ways. First, a subjective sense, viz., "I feel certain." Or, two, "I know or am certain that such and such is the case." In the second case the word certain could replace the word know, i.e., they essentially mean the same thing.

Marchesk May 31, 2020 at 13:36 #418072
Moore is also misunderstanding the skeptic. The skeptic will agree that we have an experience of having a body. But Moore is making a claim about the external world. Moore thinks waving his hands around proves that waving hands exist as such in the external world. How does Moore get from his experience of a body to an external world matching that experience? He just assumes it.

It helps to ask why skeptical doubt arose in the first place. Ancient skeptics produced various arguments for doubting dogmatic claims about the world that Moore makes. As for the coherency of doubting everything, the ancient skeptics were aware of those criticisms. One answer is that beliefs are based on what appears to be the case to someone, such as having a body with two hands to wave about, but that doesn't justify being dogmatic.

[quote=https://plato.stanford.edu/entries/skepticism-ancient/]The most widely discussed charge is that they cannot act without belief (Apraxia Charge). In response, the skeptics describe their actions variously as guided by the plausible, the convincing, or by appearances. The notion of appearances gains great importance in Pyrrhonian skepticism, and poses difficult interpretive questions (Barney 1992). When something appears so-and-so to someone, does this for the skeptics involve some kind of judgment on their part? Or do they have in mind a purely phenomenal kind of appearing? The skeptical proposals (that the skeptic adheres to the plausible, the convincing, or to appearances) have in common their appeal to something less than full-fledged belief about how things are, while allowing something sufficient to generate and guide action.[/quote]

Until one finds out they were wrong to be certain. In that case they didn't actually know what they were certain about. Unfortunately, I have been certain and wrong a few times before. Probably all of us have.

This is one argument for skepticism. We think we know various things. They we find out we don't actually know.

On Certainty Post 3

"If for e.g. someone says 'I don't know if there's a hand here' he might be told 'Look closer'.--This possibility of satisfying oneself is part of the language-game. Is one of its essential features (OC, 3)."

The language-game of doubt, and what it means in a particular context to overcome the doubt.

"'I know that I am a human being.' In order to see how unclear the sense of this proposition is, consider its negation. At most it might be taken to mean 'I know I have the organs of a human'. (E.g. a brain which, after all, no one has ever yet seen.) But what about such a proposition as 'I know I have a brain'? Can I doubt it? Grounds for doubt are lacking! Everything speaks in its favour, nothing against it. Nevertheless it is imaginable that my skull should turn out empty when it was operated on (OC, 4)."

Here we begin to see the connection between the use of the word know, and the use of the word doubt. The negation of the proposition "I know that I am a human being" illustrates this. Wittgenstein points out what it might mean, but we get a sense of how unclear the former proposition is by its negation. The negation being "I don't know that I am a human being."

What are the grounds for doubt? What are the grounds for knowing? Maybe part of the confusion lies in the fact that we can imagine situations were we can doubt such propositions. However, can we doubt the propositions Moore is using, and can we doubt them in Moore's contexts?

We can doubt his claims to certainty about an external world because it appears that he has hands. How do we really know (have certainty) the external world is as it appears to us humans? The problem is Moore's dogmatism.

If the argument is only that we can't doubt the everyday appearance of normal life, then sure. But it doesn't help Moore's case. It's just an argument for pragmatism, while Moore wants to argue for realism.

Presuppositions are the ground. And if good, they're usually solid ground - until they change.


Such as someone in antiquity presupposing the Earth was motionless. It was as obvious as waving one's hands about. The sun, planets and stars are what move. Or things upon the Earth. But it's the Earth that provides the stationary ground upon which we have a means to measure motion.

Or some such obvious appeal to the way things seemed to be prior to convincing arguments for heliocentrism.

Interesting:

[quote=https://plato.stanford.edu/entries/collingwood/] In other words, the ‘realism’ which constitutes the target of Collingwood's critique is not the ontological thesis that there exist mind independent objects, but the epistemological thesis that there is such a thing as presuppositionless knowledge of reality. Collingwood's rejection of this realism develops out of an attempt to explain how forms of enquiry which make mutually exclusive absolute presuppositions can co-exist alongside one another.[/quote]

And:

He attacked the neo-empiricist assumptions prevalent in early analytic philosophy and advocated a logical/epistemological transformation of metaphysics from a study of being or ontology to a study of the absolute presuppositions or heuristic principles which govern different forms of enquiry.


Sounds like absolute presuppositions are similar to Witty's hinge propositions. But Collingwood argues we have mutually exclusive presuppositions across different fields of inquiry, which raises a problem for using those as a basis for making claims to certainty about the world.

That just makes a mash of the meaning of the word. What do you imagine pre-suppose to mean? If I claim justification, then that is exactly not presupposing. See the problem?


If I presuppose there are good reasons for believing X, then I'm presupposing there is a justification for X. In this case presuppose means to entail.

On Certainty Post 4

"Whether a proposition can turn out false after all depends on what I make count as determinants for that proposition (OC, 5)."

This is an interesting point, many of our beliefs are indeed determined by what we make count as evidence. In fact, most arguments are over this very thing. For instance, some religious people believe there is evidence for the existence of God, but others do not believe there is evidence, or at least good evidence. Now, I am not saying that there is or there isn't evidence, only that a proposition is true or false for me or you based on what we allow to count as evidence. In fact, language-games can arise to support any system of belief. However, it's not the language-game itself that decides whether we have knowledge of this or that, otherwise we could create language-games to support any belief.

Language-games can give support for the correct use of certain words; and in the case of On Certainty, we are looking at how we use the word know. So, not all language-games are created equal. We need to look at the original use, and how a word has developed over the years, i.e., the language-game and grammar that surrounded the word's birth and growth.

"Now, can one enumerate what one knows (like Moore)? Straight off like that, I believe not.--For otherwise the expression "I know" gets misused. And through this misuse a queer and extremely important mental state seems to be revealed (OC, 6)."

This is where Wittgenstein begins to show that Moore's use of the word "know" is contrary to the word's original home, i.e., contrary to how the word is normally used. There is a kind of logic of use involved in Wittgenstein's method throughout On Certainty.

For the longest time I didn't know exactly what Wittgenstein was referring too, when he made the following statement about Moore's proposition: "...a queer and extremely important mental state seems to be revealed."

However, in a later passage he seems to clarify what he has in mind. In paragraph 42 Wittgenstein speaks of the "mental state of conviction," and that this state of conviction is something that occurs regardless of whether a proposition is true or false. Wittgenstein seems to refer to it as a subjective state of certainty, and we observe this in the way people speak or gesticulate. The way we gesticulate will often show our convictions. Moore's claim to knowledge seems to be more in line with this subjective state of certainty, than with real knowledge claims. This will be developed more as we look at these passages.

Finally, if some of you want to learn how Wittgenstein examines words using the methods in the Philosophical Investigations - I believe On Certainty puts Wittgenstein's methods (the methods of the PI) to use, i.e., we can learn how to apply his methods by a close examination of his notes.

Would you have preferred a different body part?

Probably because hands are harder to be skeptical about than a rock, since hands are part of the person doing the doubting. You can kick the rock, but it's still not as good as waving hands about.

However, it still doesn't accomplish what Moore wanted it too, unless one already agrees with Moore. A skeptic is not going to be persuaded. Moore is waving his hands to the choir.

This is very interesting. So Moore is misusing the word "know" to instead refer to a feeling of certainty.

As a side note, it's also interesting that Wittgenstein is referring to a mental state.

Well, you might say your body is part of external reality. That you have a body moving about in the world proves there is a world. Some people want to argue the subjectivity/objectivity divide is false. It's all objective. Problem is it can go the other way and be all subjective.

Where exactly is the boundary between internal reality and external reality? Presumably there is an internal reality since we're talking about external reality. Also, it seems to me that hands and other sensory organs are the interface between the internal and the external - a place, so to speak, where the external and the internal greet and converse with each other. Given this is so, I'd expect something other than bodily parts for a proof of the external world. :chin:

If proof means something like 'argument or sufficient evidence for the truth of a proposition,' then it seems to me that the very concept of proof is social. Who is the argument for? What is reason? If reason is radically private, how does it avoid being absurdly arbitrary?

The idea that was start in some kind of private mental space and have to somehow construct or justify the world from there is massive and misleading assumption. Why does our skeptic take this framework for granted? Why does the skeptic not doubt the existence of the mental, of the inner? Perhaps because the skeptic assumes without proof that language/thought is 'inside.'

Yeah. Good example. So the skeptic starts with this framework of being a voice and an eye trapped behind a screen, a fairly detailed and wild assumption, and takes it utterly for granted. 'I don't believe anything, except that there's a screen between me and everything.'

The skeptic doesn't know he has a hand but is sure he has a voice, that he ought not believe without proof, that he understands correctly what the voice (which must be his is saying). This proximity of the 'inner' voice is a massive assumption. It's 'me.' Those words in my head are 'me.' Why is the skeptic sure that he is a singular consciousness? That words imply some kind of consciousness or 'mind stuff' opposed to 'non-mind stuff.'?

By the way, I like the spirit of skepticism. I like instrumentalism as a philosophy of science. I somewhat object to saying that a table, for instance, is 'really' atoms, etc. Or that the table is 'really' sensations. This is like trying to pin down a network of interdependent meanings by making some of them fundamental. The world and language function as a glob.

There's something like a 'constructivist' paradigm that can be taken for granted where philosophers are tempted to build up the world as experienced from 'matter' or 'sensation' or whatever. I don't think that it's wrong. It squares with certain other intellectual achievements. It's just limited, and I like becoming aware of strategies that we never consciously chose but just absorbed from the conversation around us. The apparently necessary thereby becomes contingent and the conversation is enlarged.

On Certainty Post 5

"My life shews that I know or am certain that there is a chair over there, or a door, and so on.--I tell a friend e.g. "Take that chair over there", "Shut the door", etc, etc. (OC, 7)"

Our lives show that we have certain beliefs, and many of these beliefs are shown by our actions. The very act of sitting at a computer and typing shows my belief that there is a keyboard; that I have hands; that I am controlling my fingers; that what I type is saved to a hard drive, etc, etc. I don't even think about it, i.e., I don't think to myself and say, "Is this really a keyboard?" After all there is no reason to doubt it, and even if I did doubt it, would that doubt really amount to anything? That I am certain of these beliefs is reflected in what I do. We all act in ways that show our certainty of the world around us. Occasionally things do cause us to doubt our surroundings, but usually these things are out of the ordinary. I am referring to our sensory experiences, i.e., generally we can trust our senses even if occasionally we draw the wrong conclusion based on what we see, hear, smell, etc.

The backdrop of reality grounds us, if this wasn't the case, then the skeptic would have an argument. However, the skeptic tends to doubt things that shouldn't be doubted. They doubt that which is outside the language-game of doubting; and they violate the rules of doubting within the language-game of doubting. Similarly, Moore is extending the use of the word know beyond its normal use, beyond the grammar associated with the word.

I don't think you grasp what I'm gesturing at, which is admittedly a strange thing. What is thinking? Does this involve 'mental' stuff? Why believe in mental stuff is something as equally obvious as the external world is doubt-worthy? Don't all these 'concepts' live together?

The move from thinking to a thinker is substantial. But we can consider a more basic move: the move from a sequence of words into a cohesive voice that is mine. The skeptic starts not from zero but from a complicated assumption of selfhood and some 'mental' realm that acts as kind of screen between this self and an 'outer' world that may or may not 'really' be there.

Do you see this massive framework that is utterly taken for granted? Just taking the 'I' for granted as some unity of a voice that is assumed to be 'interior'? The (pseudo-) skeptic starts with an inherited situating paradigm as if it were necessary. He walks across the floor to check whether the wall is real, not noticing his trust in the floor.

I'm trying to point out a massive enactment of faith or trust that makes any particular doubt intelligible. Our skeptic doubts the 'outside' but not that the inside-outside thing might itself be a radical misunderstanding, etc. He takes the 'I' utterly for granted.

Right. It's fascinating how something inherited like this old bad idea can become the 'ground zero' of a game of doubt. I remember being stuck in this framework myself once. It's the glasses we don't know we are wearing that get us.

On Certainty Post 6

"The difference between the concept of 'knowing' and the concept of 'being certain' isn't of any great importance at all except where "I know" is meant to mean: I can't be wrong. In a law-court, for example, "I am certain" could replace "I know" in every piece of testimony. We might even imagine its being forbidden to say "I know" there. [A passage in Wilhelm Meister, where "You know" or "You knew" is used in the sense "You were certain", the fact being different from what he knew.] (OC, 8)."

This passage seems to be straight forward, i.e., in many instances we can use the two words know and certain interchangeably; and this is probably where some confusion occurs. Except, as Wittgenstein says where it's "...meant to mean: I can't be wrong." - this seems to be a reference to Moore's propositions. Moore seems to be saying that here is a hand, and I can't be wrong about this, or many of the other propositions Moore uses. There seems to be something special about Moore's propositions, and Wittgenstein picks up on this. It's probably why Wittgenstein has some sympathy for Moore's argument.

It seems to be the case that Wittgenstein uses the word certain in both the subjective sense and the objective sense. The latter is akin to knowing, the former is reflective of my inner state of subjectivity.

What did you understand by "thinker" in my last reply to you?


I may never know. We've been talking about language in Bedrock Beliefs. One of the themes is how automatic it is. If I try to tell you what I understood by 'thinker,' that will be a fresh speech act on my part. And then you can ask me what I meant by some word in that speech act.

This is connected to using words 'under erasure.' Even as we criticize them, they must retain a certain legibility that makes such criticism possible. And it's never about a simple denial that there is a unified consciousness or that there is a thinker. Philosophers can't legislate the ordinary intelligibility of these words. They are radically dependent on their blind skill, and theoretical discourse cannot be self-founded or 'purified' of this 'thrown-ness.' It can and does move against such 'throwness' by articulating and otherwise blindly enacted paradigm that only then becomes optional. As I see it, such an 'escape' is always only partial and near the surface. The thinker (singular) is always mostly the plural 'we' among whom these tokens signify in an enacted, social form of life.

Well, you were basically objecting to Descartes before in the context of his cogito argument. I did a climb down and agreed with you that an "I" is, perhaps, too complex an entity to be inferred merely from thought. In what sense is my "thinker", here merely an entity whose function is thought, inappropriate?

It's not that there's something wrong with postulating a thinker. If I were to gripe, I might say that concepts are interdependent, that our understanding of thinking is entangled with a general understanding of the world. But the original issue is that radical skepticism is 'impossible' in that it needs to presuppose some thinker who experiences representations. In that sense it's not radical enough. It takes an old-school philosophical set up for granted. I'm suggesting that we can't intelligibly get behind some kind of setup like this. Why is taking a stream of words as a unified 'I' acceptable to our radical skeptic when the external world is not? How are reality and doubt intelligible apart from others?

So, your conception of radical doubt would be to doubt everything. If memory serves, Descartes did exactly that but came to realize he couldn't doubt the doubter for he couldn't deny the truth of experiencing doubt and neither can anyone else in my opinion.

Well I guess I agree that we can't doubt the doubter in some sense. But why can we doubt the world if we can't doubt the doubter? What can doubt mean without a world? What's the difference between a dream and reality if there are no other people? I guess I'm saying that the doubter is only intelligible against the background of a shared world, that all of this is built-in to language in some sense.

Descartes finds, or thinks he finds his justified belief that cannot be wrong. But because he does it on his own, in a 'meditation', his knowledge is not of the external world, but of a purported internal world. I suspect W. found it beneath his dignity to even consider such nonsense - or else he never bothered to read Descartes. He wasn't a great reader of the canon.

Moore at least tries to start in the world, by waving his hands and addressing his fellows. but his project is Descartes' project.

Wittgenstein rejects the whole project to find a foundation for knowledge. Whatever is knowable is doubtable and knowing and doubting are activities in the world, that is to say in a context. so one can always imagine a context - waking up in hospital strapped to a gurney, where one might reasonably doubt that one has a hand,. So one sees that both knowledge and doubt are both equally justified or unjustified by the context and this context is the world within which knowledge and doubt can exist.

So the picture one might choose to replace the idea of knowledge as a building with foundations is perhaps more of a boat that floats on the Sea of Circumstance.

"Now do I, in the course of my life, make sure I know that here is a hand-my own hands, that is (OC 9)?"

The fact that we don't doubt that we have hands, at least in most cases, tells us something important about Moorean propositions. It tells us that they have a grounding that makes them exempt from doubt, at least in the contexts we are describing. This is also true of most of our sensory experiences, viz., those experiences with the world around us. Moreover, it is these experiences that seem to all fit Wittgenstein's bedrock propositions.

"I know that a sick man is lying here? Nonsense! I am sitting at his bedside, I am looking attentively into his face.-So I don't know, then, that there is a sick man lying here? Neither the question nor the assertion makes sense. Any more than the assertion "I am here", which I might yet use at any moment, if suitable occasion presented itself.---Then is 2 x 2 = 4" nonsense in the same way, and not a proposition of arithmetic, apart from particular occasions? "2 x 2 = 4" is a true proposition of arithmetic-not "on particular occasions" nor "always"--but the spoken or written sentence "2 x 2 = 4" in Chinese might have a different meaning or be out and out nonsense, and from this is seen that it is only in use that the proposition has its sense. And "I know that there's a sick man lying here", used in an unsuitable situation, seems not to be nonsense but rather seems matter-of-course, only because one can fairly easily imagine a situation to fit it, and one thinks that the words "I know that..." are always in place where there is doubt, and hence even where the expression of doubt would be unintelligible (OC 10)."

Consider the following: We are sitting together visiting a friend in the hospital. We are in a well lit room, and we are not under the influence of drugs or anything that would alter our perceptions, so there is no reason to doubt that we are looking at a sick friend. I say, "There's a sick man lying here. In fact, I know there is a sick man lying here. It's our friend Bob." You respond, "What's your point? Obviously there is a sick man lying here. Did you have any doubts?" Notice how out of place the proposition sounds. It is important to realize that if there was a reason to doubt the statement, then it would not be out of place. For example, if we were standing outside Bob's room, and it was not well lit, and you asked, "Is that Bob in there?" And I replied, "Yes, it's Bob." You ask, "Are you sure (the doubt), it's hard to see in here?" I respond, "I know that's Bob, because a few minutes before you arrived, I was in there talking with him." In this last example note how the use of "I know..." fits together with the doubt, and the resolving of the doubt. In the former example, where a doubt does not arise, the use of "I know..." seems like nonsense or silliness.

The problem it seems, is that because we can imagine a situation that fits Moore's propositions, then it follows from that Moore's propositions are good examples of what we know. But the problem may be that some of these propositions will work within the language-game, and some will not. One needs to understand the context. Therefore, is it proper to say, as Moore did, "I know I have hands." One cannot answer the doubts of the skeptic by simply using the word know, as if the utterance of the word conveys that you really do know. In fact, the statement that one knows is no more intelligible in this situation, than the statement that one doubts that one has hands. Both people are making the same mistake, viz., using the words out of the language-game that make them intelligible.

Wittgenstein seems to be making the same point about the mathematical proposition 2 + 2 = 4, i.e., when it is used outside of its normal range of use (outside the language-game in which it resides), it too, is out of place.

Consider how we use the word know in our everyday lives. We take a course in algebra, history, ethics, or physics, and the teacher wants to know if you know the subject. Is it enough to say to the teacher "I know algebra." Is that enough to alleviate the doubts of your teacher? Obviously not, we have to demonstrate our knowledge? We take quizzes, we take tests, and we answer questions in class, this is what convinces others that we have knowledge. Once the doubts are eliminated, then the question of knowing does not generally arise. If we say in a court of law that so-and-so is guilty of murder, then hopefully the evidence will convince us, so that very little doubt, or even no doubt remains. A claim to knowledge is a special kind of claim that requires an objective standard, so that we generally have no doubts that we have such knowledge. Moreover, the claim to knowledge is not a claim of absolute certainty. We do not need absolute certainty to say that we know that a proposition is true or false, but we do need a high degree of certainty. This is often seen in courts of law when the jury is told to disregard doubts that are not reasonable.

What possible doubt could there be in the examples above? Doubting has to have a context beyond the expression of the word doubt. Just as knowledge must have a context beyond simply expressing the word know. Just because someone is able to use the words know and doubt in a proposition, that does not mean that the proposition has sense.

Using the word know as Moore used it, is senseless, in fact, it creates bogus philosophical problems. Many so-called philosophical problems are just as senseless. The way we talk about free will and determinism, time, knowledge, and a whole panoply of other philosophical ideas, propositions, and words are also just as problematic. Once you come to understand what Wittgenstein is saying, or trying to do via his method, then many of the problems of philosophy simply vanish as pseudo-problems - many, but not all.

What exactly do you mean by "sea of circumstance"?

I can imagine a setting of circumstances A, B and C, etc. In A, we doubt B and C; In B, we doubt A and C; in C we doubt A and B, and so on. Noting that while in A, we're certain of A, while in B, we're certain of B and so on, it follows that we're both certain of each circumstance (A, B, C,...) and also in doubt about them.

To my reckoning, each circumstance presents a dilemma. Should I in a circumstance A, be certain of A or should I preemptively doubt it? (For) I most certainly will when I've left A and entered another circumstance, say, B? Which of, either certainty or doubt, is true of the circumstances we find ourselves in? Should I be certain, as I am when in the thick of a given circumstance or should I doubt, as I will, when I view a given circumstance experienced from the vantage point of another circumstance?

11. We just do not see how very specialized the use of "I know" is.
12. - For "I know" seems to describe a state of affairs which guarantees what is known, guarantees it as a fact. One always forgets the expression "I thought I knew".

Since they flow on, best treat them together.

Note seems.

"I know I have two hands" does not provide the certainty Moore seeks.

I once had this conversation with an Afghani man who had both legs blown off by an American fragment bomb. He assured me that Moore was wrong, and that he did indeed need on occasion to check that, in his case, he really did not have his legs.

And I think it here important to go back to the following:
"2x2=4" is a true proposition of arithmetic - not "on particular occasions" nor "always" - but the spoken or written sentence "2x2=4" in Chinese might have a different meaning or be out and out nonsense, and from this is seen that it is only in use that the proposition has its sense.


What we know depends on use; and hence, as you see from the case of my friend Soraj, on our circumstances.

Yes; and also "There is a hand there" follows from the proposition "He knows that there's a hand there". But from his utterance "I know..." it does not follow that he does know it.

If we are thinking of knowing in terms of justification - a misleading term - then the justification here is a showing. "Here is my hand - no mistake is possible".

As I understand it, we can never get outside of our blind skill and finally say what 'I know' means. We can and sometimes do use this blind skill to imperfectly articulate what's going on. I think Wittgenstein is doing that in the quotes above. And you are analyzing a use of 'I know' in context and doing a translation, a fresh creative act that relies on your blind skill with English.

[quote=link]
First of all, we learn language by interacting with others, and thus we can refer our private feelings to ourselves only after we have learned how to refer and how to distinguish between "private" and "public" in the first place. Thus the sense of what is private is derivative upon non-private communication, and there is, then, a holistic connection between any so-called private language and language's ordinary uses. Braver links this with Heidegger's holism in his description of tools in Being and Time, where the use of a tool, such as a hammer, presupposes a non-thematic understanding of an entire world of references within which the hammer functions, and this includes involvements with other human beings (other Dasein). In this regard, our existential being-in-the-world is our primary experience of everything, and it must simply be described rather than theoretically reconstructed, for such reconstruction would be a falsification.

I'm tempted to agree with you. The thought of blind skill threatens the philosophical project. The fantasy is that we can take some position on the outside and legislate. The insight, if we want to call it that, is that metaphysics (including theory of knowledge) is impossible. But all of these words are caught up in that same blind skill, in conventions and slippage that can't be controlled from the outside, some dry room from which we peep down on the storm.

Heidegger is easy to hate, and I hate him half of the time. But he's also great at times. I guess he is systematic during some phases, but at other times he's highly anti-systematic.

16. "If I know something, then I also know that I know it, etc." amounts to: "I know that" means "I am incapable of being wrong about that." But whether I am so must admit of being established objectively.


I know that I know that I know that I know... implies I am incapable of being wrong... that doubt has no place here. Juxtaposed to objectively...

I'm reading this as preparing the ground for the contention that knowledge cannot be private.

18. "I know" often means: I have the proper grounds for my statement. So if the other person is acquainted with the language-game, he would admit that I know. The other, if he is acquainted with the language-game, must be able to imagine how one may know something of the kind.


More preparation. Knowing as part of a language game, with all that this implies.

19. The statement "I know that here is a hand" may then be continued: "for it's my hand that I'm looking at." Then a reasonable man will not doubt that I know. - Nor will the idealist; rather he will say that he was not dealing with the practical doubt which is being dismissed, but there is a further doubt behind that one. - That this is an illusion has to be shown in a different way.

20. "Doubting the existence of the external world" does not mean for example doubting the existence of a planet, which later observations proved to exist. - Or does Moore want to say that knowing that here is his hand is different in kind from knowing the existence of the planet Saturn? Otherwise it would be possible to point out the discovery of the planet Saturn to the doubters and say that its existence has been proved, and hence the existence of the external world as well.


"Here is a hand", if it is to count against the idealist, cannot be part of the same sort of language game as "Here is Saturn". Rather it needs to be part of the setting up or explaining how that language game works. It's showing how the game is played.

Banno June 07, 2020 at 00:52 #421075
21. Moore's view really comes down to this: the concept 'know' is analogous to the concepts 'believe', 'surmise', 'doubt', 'be convinced' in that the statement "I know..." can't be a mistake. And if that is so, then there can be an inference from such an utterance to the truth of an assertion. And here the form "I thought I knew" is being overlooked. - But if this latter is inadmissible, then a mistake in the assertion must be logically impossible too. And anyone who is acquainted with the language-game must realize this - an assurance from a reliable man that he knows cannot contribute anything.


So here is the core criticism of Moore: If his argument is to work he must be using "I know that..." to mean "I am certain that..."; and then the inference "it is true that..." will follow. But we do say "I thought I knew that..."; and hence, certainty need not follow.

But then Witti adds: "an assurance from a reliable man that he knows cannot contribute anything." And further,

22. It would surely be remarkable if we had to believe the reliable person who says "I can't be wrong"; or who says "I am not wrong".


Which seems odd; then qualifies that with

23. If I don't know whether someone has two hands (say, whether they have been amputated or not) I shall believe his assurance that he has two hands, if he is trustworthy. And if he says he knows it, that can only signify to me that he has been able to make sure, and hence that his arms are e.g. not still concealed by coverings and bandages, etc.etc. My believing the trustworthy man stems from my admitting that it is possible for him to make sure. But someone who says that perhaps there are no physical objects makes no such admission.

24. The idealist's question would be something like: "What right have I not to doubt the existence of my hands?" (And to that the answer can't be: I know that they exist.) But someone who asks such a question is overlooking the fact that a doubt about existence only works in a language-game. Hence, that we should first have to ask: what would such a doubt be like?, and don't understand this straight off.


Moore's "I know I have a hand" needs to remove all doubt; but "I know" is not strong enough to do this. "I am certain" suffers a similar fate. But "It is certain..." does not. You might agree that I think I know, and still maintain that I am wrong; but if you agree that it is certain, then you cannot then say that I am wrong. (probably needs unpacking... complicity is achieved in the move from first person to third person).

25. One may be wrong even about "there being a hand here". Only in particular circumstances is it impossible. - "Even in a calculation one can be wrong - only in certain circumstances one can't."

Here he leaves Moore for a while, looking instead at rule following. Why?

There is a way of following a rule that is shown in implementing it, as opposed to merely stating it.
28. What is 'learning a rule'? - This.?
What is 'making a mistake in applying it'? - This. And what is pointed to here is something indeterminate.


This... shown, not said. We can recognise when the rule has been followed, or not. It does not follow that we can state all the circumstances in which the rule might be broken.

Certainty is as it were a tone of voice in which one declares how things are, but one does not infer from the tone of voice that one is justified.

What's blind about it? The term's an odd choice.


It's the way that words just pour out of us in situations. We react appropriately, like we are riding a bike. I think of someone writing a dictionary as looking around at what happens and squeezing out the least wrong summary that he can, and I understand as like a work of translation.

Along these lines, the same word used in a million different instances has a million different 'meanings.' You and I could look at these individual cases and perhaps agree on some further elaboration. We could talk about what the word means in exactly that context (ignoring that fact that we're never in exactly that context but only imagining). As we did so we'd be using the same blind skill. The words would pour out from nowhere, with more or less hesitation or rewriting. So the skill is blind as taste is blind, though of course we do create fresh words to articulate/elaborate aesthetic reactions.

I agree that the phrase you mentioned is senseless out of context. As Hegel stressed, you can't offer summarized results in philosophy. The meaning isn't there in the words. It's distributed in everything that lead up to such a summary and in the form of life that makes the book intelligible in the first place. I know that Hegel is a pain in the ass too, by the way.

I do think English translations of Heidegger are often obscure and ugly. I don't know if it's the fault of the German. Probably to some degree. At the same time, lots of philosophers may be anti-poetic enough to prioritize accuracy over a new living book in English.

What did Witt say about wanting to grunt? But then that grunt or conspicuous silence becomes a token in the game. (Heidegger also talked of conspicuous silence.)

This context thing is basically historicism. 'Meaning' is cumulative. We have to 'read ourselves in' to a certain intellectual community. Hegel, for instance, could take a certain jargon for granted. He was writing for his contemporaries. They wanted their Jesus and Progress rolled into one. How could it be made scientific? How could a certain tension in their form of life be resolved? So to study philosophy (if that means reading the famous dead) is also to study history. We try to feel our way into a form of life. This is a big theme in the Dilthey draft, as one might expect given its nickname.

To be sure, I can't choose the right words, the perfect words. What makes communication possible (inherited conventions) makes perfect communication impossible. The words aren't tied down to Platonic meanings. They drift as we keep using them in new ways and forgetting to use them in the old ways. If meaning is use, then use is unstable.

I think this actually connects to the OP. But it also extends the post above.

Tell me if the below doesn't sound one hell of a lot like Heidegger (who does acknowledge the influence, for what that's worth.)


[quote=link]
According to Yorck, the analysis and evaluation of the contemporary intellectual-historical situation is integral to philosophy—all the more so if philosophy self-reflexively grasps its ineluctably historical nature, which in itself is one of Yorck's main philosophical objectives. The basic idea for the historicity of philosophy is straightforward. For Yorck, as for Dilthey, philosophy is “a manifestation of life” [Lebensmanifestation] (CR, p. 250), a product or an expression in which life articulates itself in a certain way. But all life is intrinsically historical. Life is inconceivable without its historical development.
...
Consequently, Yorck rejects from the start the transcendental method in philosophy as insufficient for grasping lived historical reality. Transcendental philosophy reduces historical life to the merely “subjective,” which misses the genuine characteristic of Geist, spirit or mind, namely its real, historical extension and connection.
...
Yorck's primary category of historical life does not only challenge transcendental philosophy as too-narrow a foothold for philosophy. A fortiori, it also challenges the entire metaphysical tradition, which presupposes or searches for an ultimate objective reality (being, idea, substance, and so on), divorced from the ground of the always shifting historical life. Yorck rejects claims to “knowledge” sub specie aeternitatis. For Yorck, metaphysics is a flight from the historical reality ‘on the ground.’ By making historical life primary, Yorck effectively aims to dismantle the predominance of Greek metaphysics, including the modes of thought of modern science derived from it.
...
In the condensed and all too general format of the Correspondence with Dilthey, Yorck develops the practical “application” of philosophy in only the most fragmentary fashion. Its most important part is the actual clarification of the contemporary situation, the determination of the given historical possibilities, and the avenues for implementing some of them. Yorck holds that since the Renaissance and through the works of such thinkers as Galileo, Descartes, and Hobbes, the self-interpretation of life has found its centre of gravity in the cultivation of the theoretical understanding [Verstand]. The primacy accorded to theoretical understanding and what it projects as objective, unchangeable, and ultimate reality (metaphysical & physical) has ushered in “the natural sciences,” “nominalism,” “rationalism,” and “mechanism,” (CR, pp. 68, 63 & 155). But this has come at the exclusion of the full thematization, expression, and appreciation of human affectivity [Gefühl], including the underlying feeling of human connectivity through a shared life in history. Blocked-out are questions which affect the temporal, historical and personal existence of human beings, or what Yorck once calls “existential questions” [Existenzialfragen] (CR, p. 62), which relate to the life-goals human beings strive after, the recognition of dependency, and the awareness of human mortality, finitude, and death (CR, p. 120). The relative sidelining of these aspects in the psychology of human beings lies at the bottom of Yorck's diagnosis of the increasing self-alienation of modern man and the crisis of his time.

This seems confused. The idealist doesn't doubt the existence of hands. They would agree that Moore can show that he has hands. What they doubt is the move from waving hands about, or "it is certain", to saying hands are physical.

The objection to this would be that "physical" is part of the language game. Yes, but physical means real, as in hands are material, not mental. And this is what Moore is trying to establish against the idealist. That his hands are proof of a material world.

Again the objection would be that is how the language game is played. Hands are used as being part of the material world. Sure, but this is means language is used in a naive realist manner. The idealist presumably has reasons to reject naive realism, and thus to suppose that everyday language is mistaken.

For the idealist, waving hands about doesn't mean your hands are physical, it just means you have a consistent experience of waving hands about. You don't get to make that epistemic leap just by pointing to an experience.

Using the word know as Moore used it, is senseless, in fact, it creates bogus philosophical problems. Many so-called philosophical problems are just as senseless. The way we talk about free will and determinism, time, knowledge, and a whole panoply of other philosophical ideas, propositions, and words are also just as problematic. Once you come to understand what Wittgenstein is saying, or trying to do via his method, then many of the problems of philosophy simply vanish as pseudo-problems - many, but not all.


I don't understand how Wittgenstein's method makes these problems go away. In our language game we say we have could have done otherwise. Thus, we're responsible for our actions. But then there are reasons to doubt we actually could have done otherwise. So what to make of that? It would seem our language game has created a paradox.

Or take Hume's critique of causality. We talk about causes all the time. And yet the actual cause never presents itself in experience. So why is causality part of our language game?

Is it really the case that philosophers are abusing language? Or are they pointing out the questionable assumptions used to create our language games?

IMO, you are correct here. A problem is only pseudo from the perspective of a later stage in the critical conversation. The danger in 'language on holiday' talk is that it can be its own 'language on holiday' for an anti-intellectualism that wants to (mis-)take itself as critical.

This is what annoyed Gellner so much. https://en.wikipedia.org/wiki/Ernest_Gellner We can obviously also criticize Gellner, but I empathize with his frustration.

I like Rorty's use of Kuhn's abnormal/normal distinction. Successful philosophical revolutions are always 'abuses of language' that become the new norm. To fend off (all) 'abuses of language' is to fend of new philosophy, which is to say philosophy itself.

This criticism misses the point. It's our consistent experiences that make radical skepticism lack any force. The point is that doubting in some circumstances is unreasonable, i.e., our doubting needs good reasons, just as our knowledge claims do. Moreover, as Wittgenstein points out, "My life shews that I know or am certain that there is a chair over there, or a door, and so on (OC 7)."

Of course there are problems with perception, however, note that if I have a perception of X, and it turns out there was a problem with what I perceived, then obviously the doubt is warranted. Most of what we perceive is unproblematic, which is why I use the example of sitting at the computer typing. The so-called defeater for radical skepticism is in the unproblematic cases.

Just as Wittgenstein points out Moore's incorrect use of the word "know," Wittgenstein also points our the incorrect uses of the word "doubt," both have their problems. No one is saying all skepticism is problematic. One needs to come to terms with where these words break down (knowing and doubting).

There's some beautiful analysis of first, second and third person accounts here.

Because someone asserts that they know, that in itself is not enough to conclude that one does indeed know. That one knows needs to be demonstrated in one of the language-games of knowing. Even if it's determined that your not lying when you utter the words "I know...," it still is problematic without the demonstration of how you know.

Can you infer from your own utterance that you know? Yes. I can infer that I know based on the evidence that leads me to the conclusion that I know. I know that I know.

"There is a hand there" follows from the proposition "He knows that there's a hand there." If he indeed does know there is a hand there, i.e., he knows the evidence behind the claim, then he indeed knows it. However, this is a far cry from concluding that one does indeed know simply from the utterance "I know X."

Also that every dogmatic position can have an equally compelling counter argument.

Then you have Humean skepticism based on the problem of induction. A popular modern version of skepticism is Bostrom's simulation hypothesis. Then there are arguments based on the findings of science that the world we perceive is a kind of illusion.

To assert that I know is different from agreeing that you know that I know and again from a dogmatic we know.

No-one can reasonably doubt Moore when he says that he knows his hand, But how could Wittgenstein possibly know that Moore's hand is real and not a fake hand, and again, no scientific encyclopedia is going to help in telling us that we know whether Moore does or does not have a hand.

Therefore it would appear that both Moore and Wittgenstein are correct in their assessment of knowing but not in telling us about the type of knowledge they mean by knowing. If they cast aside metaphysical differences as nonexistent or irrelevant then they can argue past each other forever.

Descartes doesn't need to provide a reason for his doubt because it is self-explanatory in the same way that Moore only needs to raise his hand to prove to himself that he has a hand. This kind of subjectivism is self-sufficient, absolute and certain in all respects to the subjective I. A second or third person demonstration is redundant. The ancient skeptics had a different empirical knowledge to doubt and not this self-proving subjective kind.
Sam26 March 24, 2021 at 13:31 #514150
The point Wittgenstein is making about Moore's claim to know is that it's a misuse of the word know. Moreover, he contrasts knowing with doubting because of the close association between the use of these words. "I know..." is suppose to have the intended effect of tamping down any doubts that you don't know. Both knowing and doubting must be reasonable, i.e., the implicit rules that govern these words must be followed. To doubt everything, as Descartes did, not only trivializes the concept of doubting, but shows a fundamental misunderstanding of how doubting logically works. To doubt everything as Descartes did lacks sense. There has to be a framework in which doubting gets its meaning. That framework allows doubting to take place, to gain a foothold. You have to at least be sure of the meaning of your words, otherwise what would it mean to doubt. Descartes didn't really doubt everything. He surely didn't doubt what it means to doubt.

Radical skepticism is incoherent. On the other hand, so is Moore's argument that he knows "this is a hand." The same thing that grounds the correct use of doubting, also grounds the correct use of knowing. Both inextricably rely on the backdrop of reality itself, otherwise there is no foothold for doubting or knowing to get their meaning. Just as chess relies on the board and pieces in order to play the game. If you doubt the board and pieces, where do you go from there? You can't play the game.

The rules of language, or the rules of correct usage, tell us how we are to use these concepts (knowing and doubting). They're not created in a vacuum, but in a culture of correct usage. We can't just create our own uses, as many people do, and expect something coherent. To be fair, though, it must be said that many incorrect uses have to be pointed out because they're very difficult to see.

RussellA March 25, 2021 at 11:22 #514474
In considering the proposition "here is one hand", Moore's common sense approach of Direct Realism does not stand a chance against the sceptics, in that even though I perceive a hand in front of me , I may be mistaken, because from my perception knowledge of the world does not necessarily follow.

For Wittgenstein in On Certainty the proposition "here is one hand" is more a performative speech act than constative, where "here is one hand" is a naming by the observer of what the observer perceives rather than a description of what the observer believes to be in the world.

Wittgenstein's unaltering bank of a river within which the river of language constantly flows are these performative acts immune to the sceptic, an idea as later developed by Austin. When a dignitary performatively names a new aircraft carrier "HMS Albion", the sceptic cannot question that this is the true name of the vessel, as evidence is held in newspaper articles.

Wittgenstein's approach to the proposition "here is one hand " as performative rather than constative becomes the first step in a theory of language where public communication becomes possible potentially free of sceptical doubt.

Subsequent steps in a theory of of language would be in expanding the meaning of "here is one hand " by placing it within a coherent linguistic context and then discovering correspondences between language and the world.

In other words: I don't have the language, the language has me. And I am more within the language than the language is within me. To exist in a community where something like 'reality' makes sense in the first place is to already have learned this framework (to have learned to talk/think in terms of appearance/reality). With this in mind, there is a limit on how radical any facetious skepticism (that wants it articulate itself) can be.

The idea that there is a supporting structure to language is very important if you want to understand Wittgenstein's thinking about knowing and doubting (and words in general). The supporting structure (reality, if you will), and the culture that develops within this structure, sets the limits of use. Just as a board in chess limits the use of its pieces within the game, although, language is a bit more flexible in terms of the use of words. But, not so flexible that we can do whatever we want with the words we use. The tendency is for us to think that there is something within (the inner subjective me) that controls meaning and/or the use of words. This isn't always easy to see or understand, Moore fell victim to it without realizing the implications of his use of know.

Once we understand the limits of language (how we use words like know and doubt), then we can see how some uses of words have gone beyond the board of use. It's as if we've removed the bishop from the board and are using it in our imaginary game. However, it's even more strange than this, because others are also playing the same imaginary game. When others join in, this gives us the illusion that we're really playing the game. There is a very subtle loss of meaning when we do this. It certainly looks like we're playing the same game. After all, we're using the same pieces (same words, i.e., they're spelled the same), but we're moving them in strange ways. Ways that violate the original intent of the pieces and their use.

Yes, even a sceptic needs something, such as a set of rules, about which they can be sceptical.

Moore said that these rules are the rules of common sense, and has been criticised for not justifying to the sceptic why common sense should be the basis for the rules.

Wittgenstein said that once the proposition "here is one hand" is placed within the context of language, within a language game, as language is founded on logical propositions, and as logical propositions are beyond knowledge or doubt (being norms that are neither true nor false), scepticism is not able to function within language.

It is true that once the proposition "here is one hand" becomes part of a particular language game, both internally coherent and logical, then it becomes necessarily free from the sceptic.

However, the proposition "here is one hand" may be included within any number of internally coherent and logical language games, and the sceptic may rightly ask how Wittgenstein explained the basis on how to decide from the many possible language games the one that corresponds to reality.

OC 6 brings up an important point (Wittgenstein says an "extremely important" point) about mental states and the connection to Moore's misuse of know. I think to understand Wittgenstein's point one must understand the context of Moore's presentation, which is given before an audience. "Here is one hand," Moore's claim is that he knows this. Such a statement, as Moore holds up his hand, is what reveals the mental state Wittgenstein is writing about, i.e., according to Wittgenstein Moore's proposition is more of a conviction about what he believes, not a case of what he knows. In OC 42 Wittgenstein refers to the mental state of conviction expressed "by tone of voice in speaking, by gestures etc." Why does Wittgenstein see it this way? One reason is that Wittgenstein sees Moore's propositions as special kinds of propositions, that in given contexts can't be expressed in this way. Why this is the case is the subject of Wittgenstein's investigation in OC. We will try to bring forth these ideas as we move along.

In OC 7 Wittgenstein points out the important idea of showing a belief. He says, "My life shews that I know or am certain that there is a chair over there, or a door, and so on." Then he gives an example of showing, "I tell a friend e.g. 'Take that chair over there', 'Shut the door', etc. etc." These are only one or two examples of how we show a belief. The mere act of sitting in the chair or opening the door shows that we believe there is a chair or a door. Acts alone, show, or have the potential to show what we believe.

Yes, Moore did believe that his propositions were common sense propositions that all of us know, but Wittgenstein is challenging this idea. To most us it seems that Moore is correct. I mean if we don't know this is a hand, then what do we know?
Sam26 March 26, 2021 at 19:36 #515042
OC 9 brings up an important point about Moorean propositions. Do we in general makes sure that we know that this is a hand, or this is a tree, or that we live on planet Earth? This is not to say that there can't be instances where we doubt these propositions (OC 23), as Wittgenstein points this out, but we are not talking about contexts where it makes sense to doubt "this is a hand," but contexts, like the Moorean context, where a doubt doesn't normally arise. "Now do I, in the course of my life, make sure I know that here is a hand--my own hand, that is?" No. Do doubts normally arise about such things? And how far would we get if we did doubt such things? This brings us back to the supporting structure that gives language its foothold. The language of doubting is sustained only because the supporting structure (reality) supports it. Remove the supporting structure and there are no doubts, because there is no language. We learn to trust things first, then we learn what it means to not trust.
Sam26 March 29, 2021 at 19:08 #516246
"We just do not see how very specialized the use of 'I know' is (OC 11).

"For 'I know seems [my emphasis] to describe a state of affairs which guarantees what is known, guarantees it as a fact. One always forgets the expression 'I thought I knew' (OC 12)."

There are clearly a variety of correct uses of the words "I know," and each of these correct uses reflects one of the several ways we are able to objectively verify how it is we know that something is or is not the case. Some of the ways we verify how it is we know, include, logic (inductive and deductive reasoning), sensory experience (I know the orange juice is sweet because I tasted it), linguistic training (I learn how to correctly use words through linguistic training.), and finally, testimony (much of what we learn and know comes through the testimony of others). These are some of the ways we learn to correctly use the word know. Each of these ways gives a justification to our claim to know. One must demonstrate or show that one really does know. The claim "I know," does nothing by itself. All it is doing is showing your conviction that you know. One's conviction is only an assurance, but surely that is not enough to make the claim that you know (OC 15).

Given that this is the way we use the word know, what is the problem with Moore's proposition? The problem (one of the problems) is that Moore is using the word know in conjunction with a statement that generally has no need of justification. There are some basic statements about reality that do not need any justification, i.e., in some way they are foundational. These propositions (more like pseudo propositions) have the function of supporting our language, and hence, the language-game of epistemology. Wittgenstein never really worked out how we should describe these kinds of statements. He refers to them in a variety of ways. He calls them hinge-propositions, bedrock propositions, foundational propositions, etc. In OC 415 Wittgenstein says, "...certain propositions seem to underlie all questions and all thinking." This is one of the reasons I refer to these propositions as a kind of foundation, without which we no language. It seems to follow from this that talk of knowing falls apart without these bedrock propositions.

I think what Wittgenstein is referring to is a bedrock or foundational belief that undergirds everything. I do not think they should be called propositions.
Sam26 March 30, 2021 at 02:21 #516434
Note that if one claims to know, then it means that in some way he has verified his claim (as pointed out in the previous post). But more than this, it has to be possible for him to make sure that his claim is correct, i.e., that he really does know what he claims to know. However, in Moore's case what would it mean to make sure? Do I have a closer look at my hand to make sure it's not my foot? It's the making sure part that lacks sense in Moore's case.

If I claim to know the history of England, there are ways to verify my knowledge. And, note, that if someone doubts that you are an English historian, there are ways to remove the doubt, so to speak, by objectively verifying one's claim. The doubts of others is why one's claim to know needs justification. But what if one's claim to knowledge brings no doubt to mind. In other words, what if we generally can't doubt a particular claim (like Moore's claim, that he knows he has hands)? I'm talking about particular claims within specified contexts (for e.g. Moore's context). If Moore's claim cannot be doubted, i.e., we cannot imagine its justification, then it's not a knowledge claim. How we come to doubt someone's claim to knowledge is important in terms of understanding the correct use of know. Again, if it's not possible to doubt in a given context, then it's not possible to know. The proper doubts of others, is what tests our claims. This is why Wittgenstein points out the importance of the phrase "I thought I knew." It's the doubt that brings the negation of "I know." It's also the doubt that can affirm one's claim to knowledge.

"It's not a matter of Moore's knowing that there's a hand there, but rather we should not understand him if he were to say 'Of course I may be wrong about this'. We should ask 'What is it like to make such a mistake as that?'--e.g. what's it like to discover it was a mistake (OC 32)?"

RussellA March 30, 2021 at 10:47 #516516
Wittgenstein's proposal of the hinge proposition may close down one route for the sceptic, but opens another.

Wittgenstein said that language has meaning within the context of its language game, meaning is determined by use, and the language game corresponds to a reality. A game such as chess has rules, but different games have different rules. A language game may be internally logically coherent and correspond to a reality, but each language game will correspond to a different reality. I look at the optical illusion "Rabbit and Duck" and see a rabbit, my reality is the rabbit. Another person looks and sees a duck, their reality is the duck. We may have the same perception but arrive at different interpretations. The sceptic may rightly ask for what reason should one interpretation have precedence over another.

Wittgenstein is correct that there is no room for a sceptic within a particular language game, but as the reality of each language game is relative, the sceptic may still ask for justification as to which language game is nearer to the absolute reality.

Yes, part of what Wittgenstein said is that language derives meaning within the context of a language-game, and that meaning is closely connected with how we use a word in language-games. However, this is not to say that all language-games have the same force, or that we can arbitrarily make up any language-game and derive meaning from it. The same is true of use, I can't arbitrarily use words the way I want without the loss of meaning.

Not all language-games or all uses are correct. If I teach a child how to use the word pencil, and later the child points to a cat, and says, pencil, then their use of the word is incorrect, even if it's used in a particular language-game. Furthermore, note that use gets its force within a culture of agreement, and even this has its limits. So, there is a kind of objective reality in our agreement (at least generally). If there wasn't we wouldn't be able to communicate.

If I understand you correctly, you seem to be saying that each of us has a different reality (a subjective view of things), which in turn causes us to interpret things differently. Without getting into your use of the word reality, suffice it to say that you, just as the child in my example, cannot derive meaning based on how you, personally, use words. No more than you can play the game of chess by using your own rules. No one would know what you're doing. You wouldn't be playing the game of chess, as much as you might protest. After all, you might protest, it's my reality.

Meaning is derived within our world of reality, but it's not subjective, i.e., it's not something I personally determine. Meaning is derived from the social nature of language within the confines of an agreed upon reality (the agreement is general in nature). The fact that the Earth has one moon cannot be seen in the same light as the duck rabbit illustration. I don't look at the moon and see two moons while you see one. Reality, in general, is not like the duck rabbit picture.

You seem to think that all interpretations are equal, and this goes back to your subjective view (or the skeptics subjective view as you presented it), as if my interpretation is the only one that counts for me. However, if I want to use language as a tool to communicate, then there are standards that correspond to the correct use of the words within that language. The standard is derived from a community of language users, not through some internal reality.

If the skeptic replies "why should one interpretation have precedence over another," then one could answer, that not all interpretations are equal. In other words, in terms of language and the language-game, again, meaning is not a matter of your personal interpretation. The radical skeptic (I'm referring to a specific kind of skepticism, not all skepticism) is not playing the game correctly. And, this must be viewed from outside our subjective view. It's viewed by looking at the community of language users, not one's personal interpretation. One's personal interpretation may or may not line up with the community, and this corresponds to the correct or incorrect interpretation. When I say correct and incorrect, I'm speaking generally, if it wasn't true generally, language would simply fall apart.

I'm not denying the subjective, I'm simply saying that the subjective has nothing to do with how meaning is derived within a society of language users.

Wittgenstein isn't disallowing the use of know and doubt, he is saying that in some cases philosophers are not using the words correctly. By the way, I know that in some cases we use the word certainty as a synonym for know, but to avoid confusion I stick with Moore's use of know.
Sam26 March 31, 2021 at 10:57 #516919
My contention is that Moore's propositions are akin to strong beliefs and/or strong convictions (Wittgenstein seems to say the same thing). The tendency is for us to want to use know when expressing a strongly held belief or conviction, it seems to add some force behind our statement. However, words don't get meaning from some inward feeling or state. The constant contrast between the inner (the subjective), and the outer use of these words (societal or cultural usage) is a contrast one must keep in mind in order to get clear on the problem Wittgenstein is trying to convey. Losing this contrast causes much confusion.

Not only does Wittgenstein compare the use of know with the use of doubt, as pointed out in previous posts, but he also asks us how a mistake would be possible in Moore's use of know. Moore seems to be saying that a mistake is not possible, as he says, "Here is one hand." And, if Moore would have left it at that, he would have had a stronger case, but he attached "I know..." to the statement, and it's here that problems arise. One problem is the connection between "I know..." and doubting, and the other is the connection between "I know..." and making a mistake. Seeing these connections is important if we don't want the force of "I know.." to be such that one can leap from the utterance of a statement (OC 21) to the truth of a statement. As if I can't be wrong or making a mistake. The possibility of being wrong is logically connected to "I know..." in fundamental ways.

Wittgenstein pointed out though, earlier (OC 13), that we can infer from our own statement that we know, but not from the statements of others. It must be demonstrated that you know to others. "'I know' often means: I have the proper grounds for my statement," i.e., we want to make sure you're not making a mistake. What are your grounds (the doubt), let's double check this (making sure there is no mistake). This either leads to "Ahh, you are correct," or "There is a mistake here." The question arises, how does Moore's use of "I know..." allow for the correction? It doesn't. Moore's use of "I know.." is supposed to have the force of truth in and of itself, but that would be weird.

Moore has found something significant though, and Wittgenstein respects Moore's for this. Moore has pointed out something special about these kinds of statements (Moorean statements or facts). They seem to provide a kind of foundational belief that is not only fundamental to epistemology, but fundamental to language. For myself, I have concluded that it leads to non-linguistic beliefs, but I've said enough about that, let's not debate this again. :nerd:

Sam26 March 31, 2021 at 11:05 #516924
The purpose of this analysis is to try to dig deeper into Wittgenstein's thinking. Many of you know that I've done this before. However, in this analysis I'm trying to shed new light on Wittgenstein's thinking (i.e., new for me, not new in general).
Sam26 March 31, 2021 at 11:35 #516933
Even in mathematics we run into the same kinds of problems. Compare, "I know this calculation is correct (some long drawn out calculus calculation)," with "I know 2+2=4." It's easier to imagine the former use of "I know" being incorrect, than the latter. The latter use of "I know..." is akin to Moore's claim. What would a mistake in the latter proposition look like? What form would a doubt take?

"But can it be seen from a rule what circumstances logically exclude a mistake in the employment of rules of calculation (OC 26)?" However, Wittgenstein asks, "What use is a rule to us here?" After all if we can make mistakes in our calculations, certainly we can make mistakes in applying a rule.

Is there some rule that can be applied to Moore's propositions? No, there isn't, at best we can give something akin to a rule (OC 27), for e.g., "in normal circumstances." "And we recognize normal circumstances but cannot precisely describe them. At most, we can describe a range of abnormal ones (OC 27)."

"What is learning a rule?--This. What is 'making a mistake in applying it'?--This. And what is pointed to here is something indeterminate (OC 28)."

Understanding these points gives us a glimpse into why it's difficult to follow Wittgenstein's points about Moore. It's not clear cut, it's indeterminate. You have to wrestle your way to the finish line.
Sam26 March 31, 2021 at 12:03 #516937
One use of "I know..." that I find particularly problematic in our culture is the tendency to think that only science can give us a firm footing when it comes to epistemology. This tendency limits the use of "I know...," and stifles what it means to have knowledge. No doubt, science is an important tool in gaining knowledge, but obviously it's not the only tool. However, the tendency is for people to use science as a cudgel, as if you don't really know until science investigates it. I don't need science to tell me there is an apple tree in my backyard, at least not generally, I can see it. I don't need science to tell me the orange juice is sweet, I can taste it. Much of our testimonial evidence is not backed up by science. For example, a friend comes back from a trip to England (assuming the friend is trustworthy), and tells me that he saw this and that, I take it as good evidence that what he said is accurate, unless there is a good reason to think otherwise. There are many other examples, but I think you get the point.

Not all language-games or all uses are correct. If I teach a child how to use the word pencil, and later the child points to a cat, and says, pencil, then their use of the word is incorrect, even if it's used in a particular language-game.


I would dispute this "correctness" is determined relative to a language-game. There is nothing to indicate that one language-game would produce a more correct use of a word than another. So the game you play, when teaching your child the word "pencil" is just as correct as the other game which uses "cat" instead.

If that is the case, then the following is untrue as well. We can arbitrarily make up language-games, and derive meaning from those games.

This argument is untenable as well. There are no principles to determine what constitutes "playing the game correctly". It is a matter of your judgement, or my judgement, of whatever rules are apprehended as applicable. And this amounts to "one's personal interpretation". To step outside one's own personal interpretation, and get an objective view, or the view from "the community of language users" is impossible. So it really doesn't make any sense to assume such a thing as the correct or incorrect interpretation under these principles.

To make the judgement of correct interpretation, we would commonly refer to the intent of the speaker. But if dismiss this as a determining factor, and proceed toward a "game" system of modeling, there is no principle to determine the "correct" game, and its applicable rules.

The radical sceptic makes a valid point in pointing out that whilst Wittgenstein argues that each language game has its own set of hinge propositions, he did not justify why one set of propositional hinges should be more exempt from doubt than others.

I agree that in a sense my choice of language game is objective, in that some language games are more useful to me than others, which I why I chose the language game of 21st century western society rather than the language game of the Japanese Imperial Court during the Heian period.

AC Grayling discusses Wittgenstein in his Wittgenstein On Scepticism and Certainty, and refers to two main themes within OC - which he names OC1 and OC2.
OC 1 is a foundationalist refutation of scepticism, where beliefs are inherent within a system
and beliefs rest on foundations, such as passage 248 "I have arrived at the rock bottom of my convictions".
OC 2 is relativistic, where truth and knowledge are not absolute but vary with viewpoint and time, such as passage 65 "when language-games change, then there is a change in concepts, and with the concepts the meanings of words change."

I agree with your reply, which I would classify as being within OC 1, where language games resist local scepticism by being founded on propositional hinges, but I would also agree with Grayling that the biggest philsophical problem with On Certainty is OC 2, in that the framework within which propositional hinges operate are themselves relative, and hard to resist against radical scepticism.

Did he?


I agree that in On Certainty Wittgenstein did not use the words "the language game corresponds to a reality", but it seems to me that the inference within his writing is so strong that it would be difficult to argue that for Wittgenstein "the language game does not correspond to a reality"

Whilst Wittgenstein in his early philosophy did propose an isomorphism between language and reality, in his late philosophy, on the contrary, he was not explicit that language, being made up from language games, was isomorphic with reality.

I can only read On Certainty with the strong inference that Wittgenstein assumed a reality that language corresponded to.

Taking one example, passage 411, "If I say "we assume that the earth has existed for many years past" (or something similar), then of course it sounds strange that we should assume such a thing. But in the entire system of our language-games it belongs to the foundations. The assumption, one might say, forms the basis of action, and therefore, naturally, of thought."

On the one hand, the proposition "we assume that the earth has existed for many years"
belongs to the foundation of the speaker's language game. On the other hand, the speaker is assuming the reality of an earth existing for many years. It must logically follow that the speaker's language game must correspond with the speaker's reality.

In On Certainty, whilst Wittgenstein did not specifically say that "the language game corresponds to a reality", I would find it difficult to argue that Wittgenstein believed otherwise.

First, hinge-propositions, or what I call basic beliefs or foundational beliefs (foundation carries other baggage though), are outside any of our epistemological considerations (I think this is an accurate interpretation of W.), so they (the hinges) don't require any justification, nor can they be said to be true or false. The only kind of epistemological connection they have is that they're beliefs, but even this falls away when considering non-linguistic beliefs.

Second, the nature of these basic beliefs, is that they're all exempt from doubt for the reasons he gives throughout OC. One being, if we are referring to Moorean propositions, the doubt lacks sense, or as W. points out "what would such a doubt be like?, and don't understand this straight off (OC 24)." All basic beliefs (or hinges if you will) have this characteristic. If they don't, then they're not basic. Moreover, if it makes sense to doubt "This is a hand," in a particular context, then it also follows that, it's not basic. I think Wittgenstein gives good reasons why all basic beliefs are exempt from doubt.

I think Grayling is incorrect about this. While it's true that basic beliefs are relative to the reality we find ourselves in, it's also true that the skeptic finds himself in the same reality, so their use of the word doubt is also dependent on that reality. The use of relative here needs to be clarified.

Sam26 March 31, 2021 at 16:25 #517034
The radical skeptic doesn't seem to understand the limiting use of the language-game of doubt. Both Moore's use of know, and the radical skeptic's use of doubt have limitations, just as all words do. Wittgenstein is pointing out these limitations by showing how the words break down, how they can lose their sense. He shows how the logic behind their use is lost. It's as if I've removed the bishop from the chess board and I'm playing on some other surface. It may look familiar because it seems to be moving diagonally, but it's deceiving because although it looks like a game, it's not. At least it's not a chess game. We've removed the bishop from its natural setting where it functions, into an unnatural setting where it isn't functioning. I'm making moves that lack coherent sense.

Good - I am glad I hadn't missed something so important.

I'd ask you to consider OC 191. It seems to me he is here directly contradicting the contention that the relation between a language game and reality is one of correspondence. What counts as a fact, what counts as real, is part of the same language game.

You are close to what I think is a key unsettled issue for such exegesis: are language games incommensurable with each other? There are some texts that seem to support this, but broader considerations seem to count against it. For my part I here remind myself that both PI and OC are incomplete; OC the more so; so it is entirely possible that Wittgenstein hadn't decided the question to his own satisfaction. Further, I think considerations from Davidson and Feyerabend lead to the conclusion that since language games are far from fixed, incommensurability is quite unlikely.

I think that there is an understanding of Wittgenstein that bypasses the forced dichotomy you attribute to Grayling. But I haven't read the article to which you refer - do you have a link?

W. probably wouldn't have responded to Moore's papers if they were just expressing a conviction. At least that's my guess. There is something special about Moorean propositions, but not what Moore thinks, and this is what prompts W. response.

Ya, the skeptic would still get the same treatment as far as I can tell. OC probably wouldn't have been written if Moore expressed his argument in some other way.

If they are distinct and different language games then they are incommensurable because commensurability would produce one game. This is why equivocation is a fallacy. The logical relationship between a word's use in one game, and its use in another game, cannot be established.

However, the inclination is to assume that language, in general, is one game. But this assumption requires commensurability between the various games, to produce the one game of language. It's like the question of what does "3" refer to. Does it refer to three distinct and different objects, or does it refer to one object, the number 3? It depends on how you use it. But how could these two different ways be commensurable?

First, hinge-propositions, or what I call basic beliefs or foundational beliefs (foundation carries other baggage though), are outside any of our epistemological considerations (I think this is an accurate interpretation of W.), so they (the hinges) don't require any justification, nor can they be said to be true or false.


I think this overstates the case. It is not that they can't be said to be true or false. They are accepted as true and further justification is not needed. As hinge propositions they are what justification hinges on.

But we need to look at his depiction of knowledge via the analogies of the Heraclitian river and relativity, that is, the rejection of some fixed, unmoving point:

96. It might be imagined that some propositions, of the form of empirical propositions, were
hardened and functioned as channels for such empirical propositions as were not hardened but fluid;
and that this relation altered with time, in that fluid propositions hardened, and hard ones became
fluid.
97. The mythology may change back into a state of flux, the river-bed of thoughts may shift. But I
distinguish between the movement of the waters on the river-bed and the shift of the bed itself;
though there is not a sharp division of the one from the other.
98. But if someone were to say "So logic too is an empirical science" he would be wrong. Yet this is
right: the same proposition may get treated at one time as something to test by experience, at
another as a rule of testing.
99. And the bank of that river consists partly of hard rock, subject to no alteration or only to an
imperceptible one, partly of sand, which now in one place now in another gets washed away, or
deposited.

152. I do not explicitly learn the propositions that stand fast for me. I can discover them
subsequently like the axis around which a body rotates. This axis is not fixed in the sense that
anything holds it fast, but the movement around it determines its immobility.

305. Here once more there is needed a step like the one taken in relativity theory.

"The Earth revolves around the Sun" is a hinge proposition. But at one time "the Sun revolves around the Earth" was a hinge proposition. It was not simply a matter of correcting a mistake. The fate of man hinged on it.
Sam26 April 01, 2021 at 16:58 #517394
An important part of Wittgenstein's analysis is how he looks at Moorean propositions. Propositions like "This is a hand," "There are physical objects," and "The Earth has existed for longer than five minutes," these propositions seem to have the form of an empirical proposition. "The wavelength of light is around 700 nanometers," is an example of an empirical proposition, and it is capable of being verified or nullified. However, Wittgenstein points out that a proposition like, "There are physical objects," is nonsense (OC 35). These kinds of statements form the logical structure that supports language, which seems to be why Wittgenstein refers to them as logical concepts. They are a kind of bridge between the world and our thinking, and language itself. They are the logical bedrock from which language gains its foothold, without which the language of knowing and doubting would have no meaning. It would be like playing the game of chess without the rules that govern the game.

"I know this is a hand," "...is a misfiring attempt to express what can't be expressed like that (OC 37)"

I think this misses the point of what a hinge-proposition is. What makes something a hinge is not what people accept as true or false, which are epistemological ideas, but they are concepts that lie outside our epistemological concepts of true and false, and what it means to know. This is the whole point of Wittgenstein's challenge. If hinges can be said to be true or false, then it makes sense that we can doubt that the proposition is true or false. This idea allows Moore's problem (the problem as W. sees it) to creep back into our thinking.

If you would prefer, we can put this off until you are further along in your analysis.

As you know, the only example of a hinge proposition is a mathematical proposition. To exclude mathematical propositions from what is true or false is problematic to say the least.

The statement prior to the first mention of a hinge proposition:

340. We know, with the same certainty with which we believe any mathematical proposition, how
the letters A and B are pronounced, what the colour of human blood is called, that other human
beings have blood and call it "blood".

Between the two mentions of hinge propositions at 341 and 343 is this:

342. That is to say, it belongs to the logic of our scientific investigations that certain things are in
deed not doubted.

And the statement immediately following the second mention:

344. My life consists in my being content to accept many things.

We do not doubt hinge propositions because they are somehow beyond doubt, but rather because of everything that hinges on them. To call them into question would be to call everything that revolves around them into question. It is fundamental to the logic of our investigations that certain propositions stand without question. It is fundamental to our way of life that certain propositions are not called into question. "If I want the door to turn, the hinges must stay put (343)."

I'm going to make one more comment before moving on, because I don't want any confusion about what I'm saying. It's not true that the only example of a hinge proposition is a mathematical proposition. There are mathematical hinges, such as, 1+1=2 or 2+2=4 and so on. However, I'm not sure why you would say these are the only examples of hinges. The reason the book is written is because Wittgenstein is saying that there is something special about Moore's proposition, viz., "I know this is a hand," which is by definition, given the context, a hinge-proposition. Moreover, there are many other hinge-propositions. For example, the rules of chess are hinge-propositions.

I didn't exclude mathematical propositions from being true or false, only hinge mathematical propositions. Only propositions that are hinges (mathematical or otherwise) are excluded from truth or falsity.

I agree with some of this, but not all of it. It's the first sentence of this paragraph that is problematic.

If a proposition by its very nature is a hinge, then it's not doubtable. The hinge stands in a certain relation to the reality around us (the objects or things that make up the world), and to all the other propositions that connect to hinge-propositions. It's the hinge that stays put (which is why it's not doubtable), just as the reality around us stays put, at least generally, and it's because of this unique status that hinges cannot be doubted. They're bedrock, i.e., they allow the door to swing. The door being all the other propositions that are not hinges.

Two things must remain solid in order for most of the propositions of language (including mathematical propositions) to function. First, reality itself (the door frame), second, the hinge-proposition (hinge connecting to the door frame), these two remain fixed, which in turn allows the door of our life of language to function. If these things were not fixed, then no linguistic culture, no language-game of epistemology.

Maybe this clears some things up, but I'm not hopeful.

The radical skeptic seems to think that his doubts can take place in a rational argument, but the truth is that this kind of doubting undermines all arguments, especially the ones put forth by the skeptic. When the doubts reach this level, you can't even be sure of the meaning of your words. It's self-defeating. The doubt loses all meaning. There are rational doubts, but these must be distinguished from the doubts of the radical skeptic.

Is it even possible that the world around us doesn't exist? Is it possible that we've miscalculated in all of our calculations (OC 55)?" The answer is obvious with a little thought.

The reason why the hinge is not doubted, is because it is unreasonable to doubt it.

language game


I think that coherence and correspondence are useful concepts when discussing Wittgenstein's language games, in that it would be relatively easy to invent a language game based on bedrock hinge propositions that was internally logically coherent whilst ignoring the greater problem of ensuring that such a language game corresponded to external reality.

I am using terminology borrowed from AC Grayling's Wittgenstein on Scepticism and Certainty. That of foundationalism, OC 248 "I have arrived at the rock bottom of my convictions" and relativism, OC 65 "When language-games change, then there is a change in concepts, and with the concepts the meanings of words change". I used the link www.acgrayling.com/wittgenstein-on-scepticism-and-certainty

As Grayling concluded, "As OC stands, it stands defeated in just this way, for it only deals with scepticism at the lower, less threatening level, and fails to recognise that scepticism in its strongest form is, precisely, relativism"

Though it may be that Wittgenstein included passages on relativism in order to play devil's advocate whilst allowing him to work out his own foundationalist ideas.

On Certainty was intended to answer the sceptic. But did Wittgenstein succeed in his ambition ?

If Wittgenstein's position was that of a foundationalist - OC 88 "It may be for example that all enquiry on our part is set so as to exempt certain propositions from doubt, if they were ever formulated. They lie apart from the route travelled by enquiry" - the sceptic may validly ask why "certain propositions must be excluded from doubt"

If Wittgenstein's position was that of relativism - OC 256 "On the other hand a language-game does change with time" - the sceptic may also validly ask where is the justification that one language game corresponds more to external reality than another.

Although On Certainty is an incomplete work, could he have used more persuasive arguments ?

He could have proposed that "here is one hand" is a performative rather than constative statement, an idea Austin later developed more fully, partly based on Wittgenstein's writings.

He could have proposed that "here is one hand" is a Kantian synthetic a priori statement, where objects exist not in the world but in the mind of the observer. Wittgenstein was aware of Husserlian phenomenology, of which Kant's synthetic a priori was an important part. But as Wittgenstein seemingly was not a great reader of other philosophers, he tended to reinvent the wheel and seemingly did not take Kant's synthetic a priori as seriously as he should have.

Truth needs both coherence within a language and correspondence with the external world. On Certainty may be insightful about coherence, but could be more developed as regards correspondence.
Sam26 April 02, 2021 at 13:59 #517757
OC 66 begins the second of four divisions in W. notes.

"I make assertions about reality, assertions which have different degrees of assurance. How does the degree of assurance come out? What consequences has it (OC 66)?"

In the language-game of epistemology, which is what OC is concerned with, we make assertions about reality. For example, Moore's statement that "This is a hand," his own hand that is, is just such a statement. However, let's consider other such statements in different contexts. For instance, I'm in a room that isn't well lit, and I think what I see is a hand, I say, "I think that's a hand," as you strain to see what it is you're looking at. Another instance might be seeing what a magician presents as his hand while doing a magicians illusion. You're not sure what it is you're looking at. These kinds of statements give us differing degrees of assurance based on context. Much of what we think we know is based on "degrees of assurance," i.e., it's probability based.

One way that different degrees of assurance comes out is based on context. Are there good reasons to doubt in both of my examples. Yes. In my first example there is insufficient light, which gives rise to the doubt. In the second example we're watching the performance of a magician, whose is purposely misleading you. Again, good reasons for the doubt. However, in Moore's example one wonders what a doubt would look like. The case for a doubt in Moore's presentation seems lacking, to say the least, which is probably why Moore uses the example. "[A]re we to say that certainty is merely a constructed point to which some things approximate more, some less closely? No. Doubt gradually loses its sense. This language-game just is like that (OC 56)." This is just the way we describe what we mean by hand in English, it's part of the logic of language. It's part of linguistic training. How do you know this is a hand? It's what we mean by hand. When we teach a child how to use the word hand correctly a doubt might arise about whether the child has learned to use the word properly.

I'm going to back up a bit and try to clarify. Why is it that Wittgenstein writes OC? It's specifically in response to Moore's papers (Proof of an External World and A Defense of Common Sense).

I'm going to reference Ray Monk's book The Duty of Genius because it's probably one of the best researched books ever written on Wittgenstein's life.

"Wittgenstein's own view of scepticism remained that succinctly expressed in the Tractatus: 'Scepticism is not irrefutable, but obviously nonsensical, when it tries to raise doubts where no questions can be asked.' And it is in connection with this view of scepticism that he found something philosophically interesting about Moore's 'common sense propositions'. They do not give examples of 'certain knowledge', but, rather, examples of cases in which doubt is nonsensical. [This is the hallmark of a hinge-proposition.] If we could seriously doubt that Moore was holding up two hands, there would be no reason no to doubt anything else, including the trustworthiness of our senses. And in that case the whole framework in which we raise doubts and answer them would collapse: 'Certain propositions belong to my "frame of reference". If I had to give them up, I shouldn't be able to judge anything.' One such proposition might be the statement: 'That's a tree', said while standing in front of a tree:...

"The idea that there are certain judgements (among them, some of Moore's statements of common sense) that belong to our frame of reference [another hallmark of a hinge-proposition], and as such cannot sensibly be doubted, was developed by Wittgenstein in the work written during the eighteen months left of his life following his visit to the United States [referring to On Certainty] (pp. 557, 558, Duty of Genius)."

In OC 1 Wittgenstein comments that "If you do know that here is one hand, [taken from Moore's two papers] we'll grant you all the rest." So, Wittgenstein is challenging Moore's use of the word know in Moore's statement. However, keep in mind that the idea of a hinge-proposition doesn't even come up until later, he hasn't yet developed the idea, but if you read OC carefully you'll see how the idea immerges from Wittgenstein's thinking.

In OC 2 we again see one of the hallmarks of a hinge-proposition, "What we can ask is whether it can make sense to doubt it." Doubt what? Doubt Moore's proposition, given in OC 1. In OC 4 Wittgenstein gives another example of this kind of statement, i.e., a statement like Moore's. "I know that I am a human being." In order to see how unclear the sense of this proposition is, consider it's negation." Considering the negation of a hinge-proposition is a way of seeing how unclear it is to doubt the statement.

OC 6 asks, "Now can one enumerate what one knows (like Moore)? Straight off like that, I believe not.--For otherwise the expression "I know" gets misused." The point is that we don't know what Moore claims to know in these statements, they are unusual to say the least, and Wittgenstein points this out as he tries to figure out the nature of Moore's propositions.

So, there is a reason Wittgenstein doesn't call Moore's propositions hinges, he hasn't yet developed the idea fully. In fact he dies before ever developing the idea fully.

There is a good deal of disagreement as what stands as a hinge proposition, as a review of the literature shows. Part of the problem is a lack of examples. The point I made is that 655 is the only example explicitly called a hinge proposition. This does not mean that mathematical hinges are the only hinges.

Before any of this I gave an example of what I think Wittgenstein means by a hinge proposition:

"The Earth revolves around the Sun" is a hinge proposition.


Sam denies that it is.

I cited the example at 655 because Sam claims that:

What makes something a hinge is not what people accept as true or false, which are epistemological ideas, but they are concepts that lie outside our epistemological concepts of true and false, and what it means to know.


This is not only an incontestable example of a hinge proposition, more importantly it is contrary to what Sam has claimed. It is true that 12x12=144. Or do you too deny this?

I am well aware of 340 and 341, I cited them.

This is correct. As soon as you allow true and false to enter the picture it destroys the idea of what a hinge is supposed to be. It allows the doubt to enter the picture.

I am trying to understand Wittgenstein's objection to Moore's use of the word "know". My current understanding is as follows, and I would be interested in your comments.

Wittgenstein found Moore's common sense approach as a reply to the sceptic interesting, as it had similarities with his own nascent thoughts about hinge propositions. However he disagreed with Moore's use of the word "know".

Moore could have said "here is one hand", meaning that ontologically in the world there is an object "one hand". For Wittgenstein, "here is one hand" is a fact in the world, it is not an interpretation, it has no truth value right or wrong, is therefore not open to doubt, is therefore not open to the sceptic and therefore a hinge proposition.

Moore saying "I know here is one hand" has a different meaning, in that in the mind of the object "Moore" are sense impressions. Moore interprets these sense impressions as ontologically there exists an external world in which there exist an object "one hand" and an object "Moore". As "I know here is one hand" is an interpretation, it has a truth value right or wrong, and therefore is open to doubt, and therefore open to the sceptic and therefore not a hinge proposition.

IE - for Wittgenstein, Moore, in adding "I know", is therefore opening his statement "here is one hand" to the sceptic.

We do not question their truth we accept it.


It's true that we accept hinge-propositions, but we don't accept them because their true, truth has nothing to do with it. In fact, they're not even propositions in the true sense of the word, which is why Wittgenstein refers to them in many different ways. If Moore had said "It's true that I have a hand," it would have been just as unintelligible. In order to see how unclear the statement is, consider it's negation (as Wittgenstein points out in OC 4), "It's false that I have a hand," and here we see just how senseless the statement is. Only in certain contexts would these statements make sense, just as in certain contexts Moore's statements would make sense, but generally to utter these kinds of statements is a misfiring attempt to say what cannot be said.

And, most, if not all of the quotes you give that you think lend support to your position, don't. However, I'm not going to go through each quote when all that is needed is to look at the beginning of OC. He spells out the problems with these kinds of statements.

I may later address some of these quotes, but not at the moment.

Quick question:

Jack Torrence is delusional. He sees a bartender who isn't there.

If he questions the existence of the bartender, is he abandoning a particular language game in favor of a more open-ended one where the question makes sense?

My interpretation and the interpretations of others who agree is that Wittgenstein found Moore's statements interesting because he found something special about them, not because there were similarities in their thinking. In fact, Wittgenstein goes to great lengths to point out the contrast between the way Moore is responding to the skeptic, and the way he might respond, or the way we should respond to the radical skeptic. It is true that Wittgenstein disagreed with Moore's use of the word know, this we know for sure.

For Wittgenstein, even the statement "There are physical objects (OC 35)," is nonsense. He goes on to ask, "Is it supposed to be an empirical proposition?" Moore did say "here is one" in the sense that you put forth, but that still would have failed (if I'm following your point). Moreover, Wittgenstein isn't saying that "here is one hand" is a fact in the world. Do you see somewhere where he says that?

Reply to Luke Hi Luke,

One thing is for sure much of this depends on context, even Moore's proposition "I know this is a hand," has a use on particular occasions, Wittgenstein stipulates this. This seems to be what he's saying in OC 10 when he says, "'2x2=4' is a true proposition of arithmetic--not 'on particular occasions' nor 'always,'"
although, to be honest, I'm not sure. Again, though, consider its negation.

In Tractatus 1.1 Wittgenstein wrote - "The world is the totality of facts, not of things"

An explanation of what Wittgenstein meant may be found in Russell, who had similar views

Russell wrote in The Philosophy of Logical Atomism - “I want you to realize that when I speak of a fact I do not mean a particular existing thing, such as Socrates or the rain or the sun. Socrates himself does not render any statement true or false. What I call a fact is the sort of thing that is expressed by a whole sentence, not by a single name like ‘Socrates.’ . . .We express a fact, for example, when we say that a certain thing has a certain property, or that it has a certain relation to another thing; but the thing which has the property or the relation is not what I call a ‘fact.”

It seems to me that "here is one hand" fulfills what Wittgenstein meant by a fact in the world.

I think what Wittgenstein intends, is that it doesn't make sense to ask this question, because to ask whether they are true or false is to doubt them. The truth of them is accepted without having to say they are true, or ask of them, is this true.

I of course do not agree with this, as I see that there is no such thing as a proposition, or any sort of belief, or idea which is indubitable. That supposition seems so obviously false. Hinge propositions are a fiction and that's why it's so difficult for these people who believe in them to agree on the criteria of being such.

There is nothing unclear about the proposition: "It's false that 2+2=4." It is clearly false.

What is unclear is how we could learn mathematics if mathematical propositions are neither true nor false. We are not taught that 2+2=4 is neither true not false or 2+2= n for any number is neither true nor false.

No, but I think it follows from his ideas.


Wittgenstein clearly states that 2x2=4 is a true proposition of arithmetic. He also clearly states mathematical propositions are hinge propositions. From this it should be clear that what follows is that at least some hinge propositions, namely mathematical propositions, are true. Moore, so to speak, has no hand in the truth of mathematical propositions.

Let me try a different approach. It probably won't help, but that's life.

If Moore's propositions or hinges cannot be known, it follows that there are no grounds/justification or reasons/evidence to say they are true. If it's nonsensical to claim that Moore can know "This is a hand," then it follows that it cannot be true either. It follows also that these basic beliefs cannot be confirmed or disconfirmed, i.e., they are arational beliefs or hinges.

If we know X, then at the very least we know they're true, but Wittgenstein is claiming that Moore's statements have no grounds to secure their truth, and thus they cannot be known. Hinges are fundamental arational beliefs that ground any talk about epistemology. They are a given, part of the reality around us. They are not ordinary propositions or statements.

Yes, I know I'm repeating myself.

I think a better approach would be to let go of Moore's hand for a moment and look at what was said about mathematical propositions.They are hinge propositions and true. If this is correct then it cannot be true that all hinge propositions are neither true nor false.

That is an important point and should not be overlooked.

Quoting Sam26

Wittgenstein points to many ways in which the term "know" is used and some ways it is misused. If Moore held up his hand as said: "This is a hand" we could look and confirm that it is indeed a hand. If he raised his hand and said instead: "This is a foot" we would know that it is not a foot. We have no difficulty distinguishing a hand and foot. We know what a hand is and what a foot is.

That Moore does not hold up his foot and say "This is a hand" is significant. He does, after all, know the difference.

I don't think that holds. We can justifiably deny that his foot is not a hand, but there is no way to be certain, and that's the key distinction, that what we see empirically is indeed a hand. Fake barns may look like real barns but we cannot under any circumstances be certain beyond some empirical probability. If the criterion for knowledge is certainty, which is not true for any science, then we cannot have empirical knowledge.

Wittgenstein is clear:

"The mathematical proposition has, as it were officially, been given the stamp of incontestability. I.e.: 'Dispute about other things; this is immovable - it is a hinge on which your dispute can turn.'" (655)

It is also clear that 2x2=4 is a mathematical proposition (10) just as 12x12=144 is:

"In the first place there is the fact that "12x12 etc." is a mathematical proposition". (654)

I do hold to the idea that if a proposition is basic or hinge, then to say that it's true is just as mistaken as saying "I know this is a hand." So yes I'm saying that Banno. My interpretation of OC is not unique, there have been many papers written on this subject. However, I'm not saying there aren't instances where it makes sense to say that 2+2=4 is true. The thing about hinges is that they depend on context. If I'm teaching someone how to use the word hand in English, then I might say "I know this is a hand," i.e., I've learned that this is what I call a hand. So, in this case "I know..." means that I have learned how to use the word hand. The same can be said of 2+2=4, in some contexts it can makes sense to say it's true, other contexts not so much. I don't know what Wittgenstein would say about this. OC 10 doesn't give enough information. Moreover, Wittgenstein never edited his thoughts in OC, it's just a rough draft.

The fact that it doesn't make sense to doubt Moore's propositions, seems to also hold for the mathematical proposition 2+2=4. Can I doubt that it's true that 2+2=4. It seems senseless to doubt it.

I find no ambiguity in OC 10 regarding this. Wittgenstein plainly states that "2x2=4" is a true proposition, irrespective of any and all contexts (occasions, times):

is "2x2=4"...not a proposition of arithmetic, apart from particular occasions? "2x2=4" is a true proposition of arithmetic—not [only] "on particular occasions" nor "always"

It's easy to disregard the parts that don't fit with your interpretation, but that's not very charitable to Wittgenstein. At any rate, it seems unusually specific to be classed as a careless error.

I am saying that when you treat a statement as a hinge in the relevant way, it is not subject to doubt, and hence cannot participate in the game of assigning either truth or falsehood to it, because being false cannot be assigned to it. Despite this, hinge propositions are to be counted as true.

I'm doing this because to follow your view, that hinge statements are not true, leads to the conclusion that no mathematical statements are true. While I see that for you this may be a grammatical convenience, it's too odd a locution to be helpful.

Moore wrote that when he says "Here is one hand", it follows that "How absurd it would be to suggest that I did not know it, but only believed it, and that perhaps it was not the case!"

Does this mean that ontologically there is a world in which there is the object "one hand" and the object "Moore" ?

How does the object "Moore" know that in the world is another object "one hand" ? The only possible way that Moore could know there is another object in the world is through his sense impressions. Sense impressions such as the colour red, a sweet taste, a grating noise, an acrid smell or a silky touch.

But there is no information within these sense impressions as to what caused them, in that there is no information within the sense impression of the colour red as to what caused the emission of 700nm. Therefore, Moore can never know the cause of his sense impressions, although he may have a belief about what caused them, and beliefs can be doubted

But Moore said he did know that "here is one hand", which raises the question - how is it possible for Moore to know that "here is one hand".

We can say for certain that Moore knows his sense impressions, even though he cannot know what is causing them. As Moore is only getting his information about any external world through his sense impressions, and as sense impressions carry no information as to what caused them, it follows that Moore's thought that "here is one hand" cannot be knowledge of a world outside of Moore's mind, but can only be knowledge of a state of affairs within Moore's mind.

IE, when Moore says I know that "here is one hand", the true meaning of this is not that Moore knows what is in the outside world (even though he may believe what is in the outside world), but knows that within his mind is the concept ""there is a world outside me in which there is one hand".

But Moore said he did know that "here is one hand", which raises the question - how is it possible for Moore to know that "here is one hand".

I know with certainty that I have a back even though I cannot see it. Furthermore, this is personal subjective knowledge that I cannot doubt. You or Witt could, but I cannot.

It's important to distinguish this kind of personal certainty from Cartesian certainty of my mind, and also from personal sense-perceptual experience and opinion, and also from public scientific fact.

The color red is innate to people with normal color vision, calling it red is a learned cultural convention. To a young child there are no shades of red. Adults, especially people like artists or winemakers, educate themselves to notice shades and to expand their vocabulary for finer distinctions. Scientific measurements are not part of common discourse at all. We cannot see electromagnetic waves and what colors we do see is through complex perception preconditioned by cultural experience.

Wittgenstein's knowledge is different than Moore's I know. Empirical certainty for Witt is next to impossible, raising undeserved concerns about skepticism. However, in the reverse, if we had strong knowledge then we would be guaranteed certainty in the package.

We make an innate assumption of what 'color' an object is under 'typical daylight conditions,' which also vary geographically, and it's difficult to claim all that visual processing is purely learned, but rather a pre-existent part of the visual cortex. I'd also note that the visual spectra for color vision are centered on the color of plants, not blood, so the apparatus to see the colors we enjoy has been evolving for a very long time.

absorption, reflection, diffuse, and opacity spectra under different lighting conditions

Science can only quantify instrumental readings. The readings are interpreted (guessed) to reflect some scientific aspect of nature. Personal experiences are very far from those instrumental readings because we are only presented learned useful perceptions that we can name and potentially act upon.
ernest meyer April 09, 2021 at 14:07 #520659
Reply to magritte I agree, and there are many social connections to color, for example red meaning stop, or santa claus. I was merely saying that color itself is not learned. Children do not need to have it explained to them that colors which look different in different lighting conditions do not mean the object's color has changed. We have an innnate sense of color permanence, like object permanence, that precedes learning.
magritte April 09, 2021 at 14:28 #520665
Reply to bongo fury At least all of the above.

Color is not entirely out there for us to see even under fixed conditions. Color is an evolutionary theatrical interpretive production of our minds. With more colors we can better distinguish finer details in images. Twilight removes saturation and color from the world and we literally see less. That's why driving around in the evenings is more dangerous.

Naming can only roughly cover subjective, therefore directly incomparable, ranges of colors. Can we see shades of burgundy or green without some agreed upon standard ostensive palette?

I've been doing some reading, and it may be that I haven't paid close enough attention to Wittgenstein's idea of grammar. I think this paper I'm reading has something important to add to how OC is interpreted. However, I haven't fully grasped the idea yet, so I'm going to continue reading.

[i]A Plea for Rhees’ Reading of
Wittgenstein’s On Certainty: is
grammar conditioned by certain facts?[/i]

Sergio Mota

Abstract

"This paper is more than a plea for Rhees’ reading of the work
of Wittgenstein (particularly of On Certainty). My interest in
Rhees’ interpretation lies on its resemblance with my own reading,
on the one hand, and on its being (surprisingly) unmentioned by
other interpreters, on the other. The two core aims of this paper
focus on Rhees’ main ideas. First, I argue that although certain
facts that are accepted beyond doubt belong to the method,
which in turn is included in grammar, this does not mean that
these facts are expressions of rules of grammar. Second, I argue
that grammar is not conditioned by a certain class of facts (i.e.
general facts of nature), but a language-game is possible because
we do not call in question certain facts (i.e. grammar is not
conditioned by something like ontology). The point is that those
facts that are not called in question are beyond truth and falsity,
but this does not mean that these facts must be true. The logical
role these facts (and the sentences used to express them) play
in a language-game is not that of being true or false. Moreover,
grammar itself constitutes what is meant by ‘object’, ‘fact’, or
‘general fact of nature’."

[i]A Plea for Rhees’ Reading of
Wittgenstein’s On Certainty: is
grammar conditioned by certain facts?[/i]
Sergio Mota

"Accordingly, the goal of this paper is twofold, as it were. On the one hand, it is my interest to show that the proposition ‘grammar is conditioned by certain general facts of nature’ has no metaphysical, absolute
sense (i.e. that ontology does not condition grammar). By the expression “metaphysical sense” I mean expressions that refer to the essential, necessary, and universal features of reality. Thus, to say that grammar is conditioned by certain facts of nature may mean that there are essential and necessary features of reality such as general facts of nature, and that this is a truth about reality, which by way of different mechanisms, for instance by repeated exposure, condition our grammar. Furthermore,
to say that grammar is conditioned by certain facts sounds as though there was an absolute conception of grammar, as though everything we call grammar was conditioned by facts. However, I do not read Wittgenstein as though he were relating a bit of language to a bit of the world. In other words, we are not relating a bit of grammar and a bit of the world as though they were ontological items. Rather, in the same sense that grammar tells us what kind of object a thing is, grammar tells us what is meant by fact. But this does not mean that facts condition our grammar, or that objects condition our grammar (see below for further discussion). So I am not rejecting that there is a relationship between grammar and facts, I am just saying that this relationship is not captured by speaking of facts as conditions.1 However, when it is said that grammar is conditioned by certain general facts of nature it seems that it is the grammar as a whole that is conditioned, without focusing on concrete language-games. It seems that it is claimed that this class of general facts of nature is that on which the possibility of language itself
depends. I think that this is a metaphysical illusion produced by projecting onto reality what should remain within grammar (i.e. grammar tells us what is a general fact of nature)."

As is mentioneded this paper Rhees' has something important to tell us. And, along with this, is must be mentioned that Rhees' had discussions with Wittgenstein on this topic. Therefore, his insights shouldn't be overlooked.

So, there is a distinction according to this paper between the proposition that 'grammar is conditioned by certain general facts of nature,' and the idea that "grammar as a whole is conditioned, without focusing on concrete language-games" i.e., that a certain set of general facts of nature, gives us the possibility of language. So, language depends on reality in some important sense. The question arose, "How could language be conditioned by certain facts of nature?

I'm not sure I quite understand this yet. Time to read on.
Sam26 April 14, 2021 at 13:20 #522755
Before going on I have to say that I'm reconsidering the idea that basic mathematical propositions are hinge-propositions. Although, with the caveat that there is a lot of debate on this issue. Moreover, it's not a simple issue to resolve. So, Moore's proposition, viz., "I know this is a hand," is not the same as 2+2=4 in terms of a hinge. The problem though, is that there are similarities between the propositions of mathematics and Moore's propositions, and Wittgenstein used mathematical propositions to bring out some point of comparison, or to clarify some point. The comparison of the two statements (Moore's propositions and basic math propositions) has given rise to the idea that basic mathematical propositions are hinge-propositions.

If you are going to say that basic mathematical propositions are hinges, then you have to be consistent and say that they are not true or false in the same way that Moore's hinge-propositions are not true or false, i.e., not epistemological.

A Plea for Rhees’ Reading of
Wittgenstein’s On Certainty: is
grammar conditioned by certain facts?


The reason I'm bringing this up has to do with a particular interpretation of Wittgenstein that is probably incorrect. Moreover, I want to check my own interpretation against the points brought up in this paper.

So, the question is, is language conditioned by certain facts of nature? First, what does it mean to say that language is conditioned by facts of nature? According to this paper conditioned by certain facts means something like "that there are essential and necessary features of reality such as general facts of nature, and that this is a truth about reality, which by way of different mechanisms, for instance by repeated exposure, condition our grammar (p. 78)." The question is, is this what Wittgenstein is saying? It's one thing to say that without reality there would be no language, but it's another thing to say that language is conditioned by certain facts of reality. Another way to say this, if I'm correct, is that language had to form in a certain way because of particular facts in nature or reality. It would be like saying that objects in nature condition our grammar (as pointed out in this paper).

The paper isn't rejecting that there is some kind of relationship between the facts of reality and language. It's rejecting the notion that language is conditioned by these facts. "[T]his is a metaphysical illusion produced by projecting onto reality what should remain within grammar (i.e. grammar tells us what is a general fact of nature) (p. 78)."

My idea has been that reality is foundational to language, i.e., that without reality there would be no language. This seems obvious.

Finally, this paper is contrasting the IMoyal-Sharrock’s interpretation against the Rhees' interpretation. The Rhees' interpretation is important because of his association and discussions with Wittgenstein regarding OC.
Sam26 April 15, 2021 at 12:03 #523151
The problem that arises, is with the idea that since language is not completely independent of reality, it may lead to the incorrect idea that language is conditioned or determined by facts of nature. This does seem to fly in the face of how Wittgenstein viewed language, viz., that it is autonomous. That language is autonomous has nothing to do with language being completely independent of language, but rather that, it is not "...accountable (or answerable) to any reality in terms of correction; and it is, in an important sense, arbitrary (p. 80)."

And also, "...language itself, grammar itself, constitutes what is meant by fact, and hence by reality. This is why grammar is presupposed when we speak of facts. In other words, in order to speak about facts
we already presuppose a grammar that constitutes what is meant by fact (p. 79)."

I'm still reading the article.

Seeking continuity, I have in mind the notion of logical space from Tractatus when considering the relation between language and the world... as in, in logical space, anything consistent can be said; but only a small subset of what can be said gives us a picture of the world that is true. So I'm understanding the autonomy of language as somewhat analogous to logical space, but using use instead of mere reference; something like only a small subset of the possible things that might be said are actually useful...

Nice!
Banno April 16, 2021 at 07:19 #523468
Then...
According to Rhees ([24, p.55]), there is nothing by which our grammar is determined. Here, Rhees is referring to what Wittgenstein calls in the Tractatus Logico-Philosophicus (TLP, [28]) “logical syntax” or “logical grammar” (cf. 3.325). To think that our grammar is determined by something is, by the time of TLP, to think that a symbolism is deter- mined by ontology.


p.83

Yeah, seems I'm following Reece here.
Sam26 April 17, 2021 at 11:14 #523904
The arbitrariness feature, an aspect of the autonomy of grammar,
does not mean that it is unimportant, capricious, or even discretionary;
it means, and this point is crucial, that it cannot be said that grammar
is correct or incorrect, right or wrong, by appealing to how things are
in reality (cf. [5]).
p. 80

So, if I understand this correctly, when using the concept fact (state of affairs), it's not what's in reality that determines how we use the word fact, rather, it's the grammar involved in language that determines it's correct use. So, our grammar is isolated from reality in an important sense, and that sense seems to be how we use language in a culture, and it's arbitrary features. There is nothing in reality that tells me how to use the word fact correctly. The arrangement of things in reality (the state of affairs) is not what determines the correct use of the concept fact.

In the same vein, Wittgenstein, in his Philosophical Investigations ([29], 1953, PI), claims that grammatical rules can be called arbitrary if that means that the purpose of grammar is the same as the purpose of language (cf. PI, §§372, 496, 497), and points out in Zettel (1967, Z) that cookery rules are not arbitrary because cookery is defined by its purpose, while grammar – or language – is not (cf.Z, §320). Thus, “[d]ifferent grammatical rules, unlike different cookery rules, are not right or wrong, but rather determine different concepts”([4, p.193]).3
p.80

It wouldn't be correct to say, it seems to me, that there is no correct or incorrect use of grammar, but that there is no correct or incorrect use as defined by something in reality. By comparison Wittgenstein points out "...that cookery rules are not arbitrary because cookery is defined by its purpose, while grammar - or language - is not (Z. 320)." So, the rules of bread making, for example, are correct or incorrect based on how the bread turns out, i.e., the outcome in reality determines the correct or incorrect recipe. It's in this sense that the recipe for bread making is not arbitrary. However, the rules of grammar are arbitrary, i.e., they are not dependent or determined by reality.

The question, at least for me is, how does this affect what Wittgenstein means by hinge-propositions? Is epistemology completely determined by the rules of grammar, or is it akin to cookery rules?









Luke April 18, 2021 at 03:08 #524188
Thanks Sam. An interesting paper and I found myself agreeing with some of it. However, I think the main thesis of the article is undermined by the quotes presented by the author (on p.85 of the article) that get dismissed a little too easily, imo. The same quotes from Part II of PI:

365. If concept formation can be explained by facts of nature, shouldn’t we be interested, not in grammar, but rather in what is its basis in nature? —– We are, indeed, also interested in the correspondence between concepts and very general facts of nature. (Such facts as mostly do not strike us because of their generality.) But our interest is not thereby thrown back on to these possible causes of concept formation; we are not doing natural science; nor yet natural history a since we can also invent fictitious natural history for our purposes.


"If concept formation can be explained by facts of nature..." The main thesis of the article is the rejection of this possibility. But Wittgenstein does not appear to rule it out. He states only that it is not of philosophical interest, or is not a philosopher's goal/purpose to discover.

366. I am not saying: if such-and-such facts of nature were different, people would have different concepts (in the sense of a hypothesis). Rather: if anyone believes that certain concepts are absolutely the correct ones, and that having different ones would mean not realizing something that we realize — then let him imagine certain very general facts of nature to be different from what we are used to, and the formation of concepts different from the usual ones will become intelligible to him.


Here W rejects the idea that "certain concepts are absolutely the correct ones", as though nature carved herself at the joints for us and we just pinned labels within those ready-made contours. But I think the paper may go too far the other way in suggesting (if I recall it correctly) that our language is therefore independent from nature or self-contained. This would seem to undermine the author's references to "the method", or to comparing propositions with reality, because what difference could such a comparison make if our concepts were unaffected by reality?
Sam26 April 18, 2021 at 03:33 #524202
Reply to Luke As I read it, the author isn't saying that grammar is completely independent of nature. He makes this clear in the first part of the paper. Moreover, I haven't decided yet if I'm in complete agreement or not. Grammar does seem to have an arbitrary aspect to it though.

Bedrock Beliefs and Their Epistemic Importance

(My Philosophic View of Wittgenstein’s On Certainty)


Biographical Sketch:

Ludwig Wittgenstein was born in Vienna, Austria in 1889. He was the youngest of eight children, five boys and three girls. His father, Karl Wittgenstein, was a remarkable man who became a leading industrialist in the iron and steel industry; consequently, the Wittgensteins were very wealthy. In addition, Ludwig’s mother, Leopoldine, had exceptional musical talents and passed her love of music to the children. As a result, all the Wittgenstein children were exceptionally gifted with artistic talent and superior intelligence.

At a young age, Ludwig demonstrated an interest in machinery, which led to his interest in engineering. He was educated at home until the age of 14, then was sent to Linz in northern Austria to further his studies. After his education in Linz, Wittgenstein went to Berlin to study engineering (1906-1908). In 1908 Ludwig enrolled at the University of Manchester in England to study aeronautics. His research eventually led to the design of a jet reaction propeller, which was a mathematical endeavor. The mathematics of his research eventually led him to the philosophy of mathematics. Specifically to the Principles of Mathematics, published in 1903 and written by Bertrand Russell (not to be confused with the Principia Mathematica, published in 1910 and written by Russell and Whitehead). The main goal of thePrinciples of Mathematics was to establish that the propositions of mathematics rest on a few logical principles. Another mathematician from Germany named Gottlob Frege was also working on the same idea. Wittgenstein eventually meets with Frege to discuss some of his thoughts, and consequently, Frege recommends that he go to Cambridge to meet Russell. Russell sees talent in Wittgenstein, which encourages Wittgenstein to pursue philosophy.

If you want a more in-depth biography of Wittgenstein, there are plenty of books to read (e.g., Ludwig Wittgenstein by Ray Monk and Ludwig Wittgenstein by Norman Malcolm).

I will set out an epistemological theory that enunciates a particular set of propositions derived from Wittgenstein’s final notes called On Certainty, published in 1969. These bedrock beliefs (often called hinge propositions) were identified mainly by Wittgenstein in the final years of his life (1949-1951). I am not claiming anything original in my thesis except to point out that bedrock beliefs have an essential epistemological role that advances the subject of epistemology in ways that few philosophers, if any, before the writing of On Certainty, have considered. I am also not claiming that my thoughts necessarily agree with Wittgenstein’s, nor am I claiming that they disagree. Nevertheless, my thinking on this subject would not have gone in the direction it did without Wittgenstein’s keen intellect expressed in the Philosophical Investigations and in his final notes called On Certainty (hereafter referred to as OC).

Wittgenstein begins OC as a response to G.E. Moore’s papers, A Defense of Common Sense (1925) and Proof of an External World (1939), in which Moore lists several propositions that he claims to know with certainty, such as, “Here is one hand” and “There exists at present a living human body, which is my body.” These propositions supposedly provide Moore with proof of the external world, and as such, they seem to form a buttress against the arguments of the radical skeptic, which is why Moore is making the argument.

Moore says, “I can prove now, for instance, that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, ‘Here is one hand’, and adding, as I make a certain gesture with the left, ‘and here is another’. And if, by doing this, I have proved ipso facto the existence of external things, you will all see that I can also do it now in numbers of other ways: there is no need to multiply examples. But did I prove just now that two human hands were then in existence? I do want to insist that I did; that the proof which I gave was a perfectly rigorous one; and that it is perhaps impossible to give a better or more rigorous proof of anything whatever. …(G.E. Moore, Proof of an External World, 1939).”

It is undoubtedly the case that OC goes beyond Moore’s propositions, so it is not just about Moore; it is about knowing, doubting, making mistakes, reality, empirical statements, certainty, acting out beliefs, rule-following, etc., so it covers a range of topics about what we know, and how it fits into our language. It is important to note that not everything in OC should be seen as a response to Moore. However, Moore provides the impetus for Wittgenstein’s final notes and is mentioned throughout OC.

Wittgenstein criticizes Moore’s use of the word know and the skeptic’s use of the word doubt, and he emphasizes the relationship between the use of these words as an essential part of the language-games of everyday epistemology.

Bedrock beliefs provide the grounding for our language-games, which is analogous to how the rules, the board, and the pieces in chess function as the grounding (reality background) for the game of chess. In fact, without these beliefs it is hard to imagine how language would get off the ground. It would be like trying to imagine a game of chess without the rules, the board, and the pieces. For example, there would be no such thing as a bishop move without the rules, the board, and the pieces. Such a move would be nonsense. The same is true of our concepts, namely, knowing, doubting, making mistakes, rule-following, etc.; these would all be nonsense without the grounding of certain primitive or bedrock beliefs. Such beliefs are at the heart of a correct understanding of knowledge, directly affecting phrases like “I know that such and such is the case” and “I doubt that such and such is the case.”

Although Wittgenstein criticizes Moore’s propositions, he is not entirely unsympathetic to Moore’s argument, which would look something like the following:

1) Moore knows that he has two hands.
2) Moore makes the inference from the fact that he has two hands to conclude that an external world exists.
3) Hence, Moore knows that an external world exists.

Post 2 continues...

OC begins with the following statement:

“If you do know that here is one hand, we’ll grant you all the rest (OC 1).”

Wittgenstein grants that if Moore knows what he claims to know, then Moore’s conclusion follows. Nevertheless, Wittgenstein argues throughout his notes that Moore does not know what he believes he knows. However, I think we are all inclined to agree with Moore. After all, if we do not know this is a hand, then what do we know? This inclination to use the word know as Moore uses it sets in motion Wittgenstein’s response. Is Moore justified in believing his claims are true? The answer to this question directly affects Moore’s proof because he assumes that the propositions he identifies are typical, which they are not.

Wittgenstein asks whether it generally makes sense to doubt that we have hands (OC 2). This question is crucial to Wittgenstein’s argument because it helps identify fundamental, bedrock, or primitive beliefs. Of course, there are situations where doubt about the existence of our hands would make sense, and Wittgenstein points this out (OC 23), but not in the context of Moore exclaiming, “Here is a hand, and here is another hand.” Nor would it make sense as given in a proof.

There are at least two kinds of bedrock beliefs. First, those we observe apart from the use of language. For example, the belief (seen especially in animals and young children) that we have hands and the belief that we are a body separate from other bodies. This is why some philosophers refer to these beliefs as animal beliefs, because of their fundamental or primitive nature. The act of using a hand or moving through space in relation to other objects shows these beliefs. This is not only observed in nonlinguistic children and animals but is apparent in all of us, irrespective of language.

The point of emphasizing the prelinguistic nature of these beliefs is to demonstrate their primitive nature. Bedrock beliefs prescind language. Thus, the ontology of bedrock beliefs gives them a unique standing in relation to our epistemic language. Wittgenstein points out the special status of bedrock beliefs in his opening remarks: does it make sense to doubt them (OC 2)? Again, their status (arational or non-epistemic status) is such that epistemic language would necessarily fail without them.

The second kind of bedrock belief is foundational but not bedrock. If we think of the foundation of a building, it is layered, starting with bedrock. On top of bedrock are other foundational components not as firmly in place as bedrock, but part of the foundation nonetheless. In other words, our prelinguistic beliefs are the bedrock of language. They are the precursor beliefs that allow language and life’s actions to take root. So, although one can refer to certain linguistic beliefs as bedrock (I prefer to separate them from other foundational beliefs), they stand out because they are less susceptible to change. For example, the bedrock belief that I have hands or am a body separate from other bodies will remain fixed for the foreseeable future. On the other hand, the rules of chess are foundational to the game, but they are a different kind of foundational belief; that is, they arise within language. The same is true of the rules of grammar, which are necessarily foundational to language use. However, although the rules in these two examples are foundational, they are not bedrock; that is, they are not as primitive or as fixed as there are objects (other people, trees, mountains, etc.) Many foundational beliefs can more easily change over time. For example, the rules of chess have changed over the years, and grammar rules have also changed.

If we return to the example of a building’s foundation, nothing is more fixed than bedrock; it is the foundation’s most fixed point. And if we look at the construction of a building’s foundation above bedrock, some foundational elements are more fixed than others and less susceptible to change. Wittgenstein’s riverbank analogy suggests much the same thing in the following:

“And the bank of that river consists partly of hard rock, subject to no alteration or only to an imperceptible one, partly of sand, which now in one place now in another gets washed away or deposited (OC 99).”

Bedrock Beliefs and Their Epistemic Importance

(My Philosophic View of Wittgenstein’s On Certainty)

Post 3


Wittgenstein points out that Moorean propositions (hinge-propositions) do not have a clear sense when trying to fit them within an epistemological framework. Consider the following quote:

“’I know that I am a human being.’ In order to see how unclear the sense of this proposition is, consider its negation (OC 4).”

Why does Wittgenstein ask us in OC 4 to consider the negation of the knowledge claim? Because a knowledge claim always stands in contrast to a counterclaim. They are claims or beliefs that have the proper justification for their conclusion. However, if the sense of your claim (your justification) to know is not clear, then it would follow that the claim to not know would be equally unclear. For example, knowing how to play the game of chess is logically connected with what it means to not know how to play the game. Knowing and not knowing necessarily play off each other. This is why Moore’s propositions lack sense. He claims to know “This is a hand,” but exactly what would it mean in his context to not know? This seems to be Wittgenstein’s point in OC 4. If you want to know what a hinge-proposition is, one need only look at the relation between the claim to know and not know (questioning whether one knows brings in the doubt) and whether both lack sense in relation to the belief. This is exactly the problem with Moore’s propositions, which is why the use of these beliefs (hinge-propositions) is not generally epistemological. What makes it difficult to understand Wittgenstein’s point is that hinge-propositions often have a use within our epistemological language-games, which seems to be why he still refers to them as propositions. They have a special role in our language. They are not propositions in the normal sense. They have a dual role, functioning mostly as bedrock beliefs, but sometimes taking on the role of standard propositions.


The epistemological use of “I know…” presumes a justificatory foundation for one’s conclusion. The nature of giving a justification is supposed to nullify a counterclaim, alleviate or remove the skeptic’s doubt, or demonstrate the objective certainty of your claim. A knowledge claim stands in contrast to its negation, and if the negation is not clear, then neither is the justification. This fits Wittgenstein’s point that “I know…” is very specialized (OC 11).

What does it mean that a knowledge claim stands in contrast to its negation? It means that any epistemological claim to knowledge must be demonstrated, and if the claim does not stand up to one of the language-games of justification, then your claim to know is not valid. Hence, the response “You do not know,” or “I thought I knew,” or any other negation of the claim. Again, any claim to know stands in contrast to what it means to not know.

The tendency is to use the phrase “I know…” as a sort of guarantee that you indeed know (a kind of inner state), does not guarantee anything. The epistemological use of “I know…” is not a reflection of one’s inner certainty or conviction. It reflects objective certainty based on a proper justificatory foundation. The correct epistemological use of “I know…” is often met with the questions, “How do you know (the doubt)?” What is your justification?

Confusion often arises when using the phrase “I know…,” and Moore’s use of know reflects this confusion. It is a paradigm case. In Moore’s case, the confusion is more challenging because of our strong convictions about such beliefs. After all, Moore believes he is justified (at the very least, it is a sensory justification), and most would agree with Moore’s argument because it seems so evident that we know we have hands in Moore’s context.
Sam26 September 15, 2023 at 11:55 #837740
As I've pointed out before, Wittgenstein talks about two kinds of certainty in OC, subjective certainty and objective certainty (for e.g. OC 245). Wittgenstein believes that Moore's propositions amount to no more than a conviction of what he believes (subjective), as opposed to having objective grounds for his beliefs (referring to Moorean propositions). So Moore's language-game doesn't do what Moore thinks it does, viz., provide a proof of the external world. So Wittgenstein rejects Moore's language-game, and all such language-games that amount to a subjective knowing, i.e., the mistaken idea, common in many quarters today, that "I know..." is purely subjective (one's conviction).

For me, OC provides the best foundation for understanding epistemology, and should be used as our starting point for understanding epistemology. OC also provides the grounding for knowledge, i.e., the starting points which have no epistemological grounding. Witt demonstrates where knowing ends, or where justification ends. He ends the infinite regress of reasons, and the circular nature of many epistemological theories. In other words, Witt solved these two problems. More work needs to be done on the nature of these pre-epistemological beliefs (Moore's propositions) and their place in the epistemological landscape.

We have to get away from our emphasis on the internal in relation to objective knowledge.

So Moore's language-game doesn't do what Moore thinks it does, viz., provide a proof of the external world. So Wittgenstein rejects Moore's language-game, and all such language-games that amount to a subjective knowing, i.e., the mistaken idea, common in many quarters today, that "I know..." is purely subjective (one's conviction). This idea has wrecked havoc on many belief systems. It's very destructive.


Is it that Wittgenstein rejects Moore’s language-game or that he is showing Moore what a language game is? Does the idea of rejecting a language-game make sense?

We know that there are many different language-games, and some of these language-games, (e.g. religious and political language-games) don't always reflect the facts. So I think Wittgenstein is pointing out how Moore's language-game fails to give a proof of the external world (Although, to be fair, Witt doesn't speak of Moore's argument in terms of a language-game). Moreover, Moore knows what a language-game is because he sat in on many of Wittgenstein's lectures.

Your 2nd question is something I thought about for a long time. I think we reject certain language-games all the time because they often don't reflect facts. So yes, I think it does make sense. In fact, it's important that we recognize that certain language-games don't reflect reality. There are constant battles between competing language-games, i.e., which language-games will prevail in our systems of belief.

I like Jasmin Trachtler’s reading of the above quote:

“…even if grammar or concept formation corresponds to
general facts of nature, this does not mean that grammar
can be explained causally, nor that it can be justified by
“nature”—it merely means that grammar does not seem to
be completely random in a trivial sense. Grammar is, as
Wittgenstein says, autonomous (cf. BT 236r)—autonomy,
however, is not absolute independence as it is not a
“complete detachment.” We might have as well other terms
and make other conceptual distinctions. As Wittgenstein
emphasises, both in the 1930s and in his later
investigations, our concepts cannot be justified as the
“right” ones or as corresponding to “nature”: they are
neither “reasonable” nor “unreasonable,” neither “right”
nor “wrong.” As he puts it, the belief that “our concepts are
the only reasonable ones consists in […] [t]hat it doesn’t
occur to us that others are concerned with completely
di!erent things, and that our concepts are connected with
what interests us, with what matters to us” (LW II, 46).
With this, however, Wittgenstein does not want to set up a
hypothesis:


I am not saying: if such-and-such facts of nature
were different, people would have different
concepts (in the sense of a hypothesis). Rather: if
anyone believes that certain concepts are
absolutely the right ones, and that having
di!erent ones would mean not realizing
something that we realize—then let him imagine
certain very general facts of nature to be
di!erent from what we are used to, and the
formation of concepts di!erent from the usual
ones will become intelligible to him. (PPF, xii,
366)

Reply to Sam26 Reply to Joshs has an idealist bent, and so is perhaps suggesting that any language game will do.

There's a pinch of truth in saying language games do not reflect the facts, since the facts, being truths, are a part of the language games around truth. Better perhaps to say that the games are embedded in the world – so the builder's game inherently involves slabs and blocks and cannot be played without them.

There's also the ill-informed supposition that language games only ever involve language, which even a cursory reading will evict.

While he shows that Moore's use of "know" in "I know this is my hand" is problematic, I suspect Wittgenstein pretty much agreed with the argument Moore presents against idealism. "Here is a hand" shows that there is stuff around us to be dealt with, providing a foundation, a certainty. Again, there have to be slabs in order to engage in the builder's game

I've always related this stuff to justification. To 'know' is to have justification, which is to have evidence. so the problem with knowing that this is a hand is that the evidence is this: *waves hand, slaps the sceptic hard on the cheek*.

As I read On Certainty it is not that one cannot doubt but that we do not doubt.

We are certain that the Earth revolves around the sun. In earlier times people were certain that the Sun revolved around the Earth. The Copernican Revolution was not simply a matter of exchanging places. It is that man is displaced from the center.

140. We do not learn the practice of making empirical judgments by learning rules: we are taught
judgments and their connexion with other judgments. A totality of judgments is made plausible to
us.
141. When we first begin to believe anything, what we believe is not a single proposition, it is a
whole system of propositions. (Light dawns gradually over the whole.)
142. It is not single axioms that strike me as obvious, it is a system in which consequences and
premises give one another mutual support.

152. I do not explicitly learn the propositions that stand fast for me. I can discover them
subsequently like the axis around which a body rotates. This axis is not fixed in the sense that
anything holds it fast, but the movement around it determines its immobility.

I would say it's more than problematic. One cannot doubt the very thing that gives rise to knowing and doubting. So, I would say in many cases (especially in Moore's case) that his use of know is senseless. Wittgenstein seems to say that Moore's use of "I know..." is more like a conviction (OC 86, 91, 103). Witt is sympathetic to Moore's argument, but he implies throughout OC that Moore's use of know is not epistemological. It's not epistemological because Moore's use goes beyond the language-game of knowing, Bedrock beliefs are what ground our epistemological language-games. Justification comes to an end with certain kinds of bedrock beliefs, i.e., animal beliefs or prelinguistic beliefs. Of course not all bedrock beliefs are prelinguistic, some are intrinsic to many of our language-games.

I would agree that many philosophers do treat knowing as if it's a metaphysical claim (many people do this, not just professional philosophers), at least that's what their use of know amounts to. However, what Moore is appealing to, is a mental state of knowing (he does this without realizing it, or if he does realize it, it's an appeal to what we all take to be a self-evident truth or common sense), which is why Wittgenstein talks about Moore's propositions as an expression of a conviction. We see this from the beginning of OC; "[f]rom it seeming to me-or to everyone-to be so, it doesn't follow that it is so. Moore is appealing to our common sense, i.e., if we don't know this (Here is a hand.), then what do we know? This is why Moore's argument is so appealing. How can anyone doubt that this is a hand, and that we know it's a hand? Moore's proof would be something like the following:

1) Moore knows that he has two hands.
2) Moore makes the inference from the fact that he has two hands, to the conclusion that there exists an external world.
3) Hence, Moore knows that an external world exists.

It follows necessarily. Especially if we do know these Moorean propositions, which is why Wittgenstein says at the very beginning of OC, "If you do know that here is one hand, we'll grant you all the rest (OC 1)." However, does Moore know, and can the skeptic doubt these Moorean propositions. Wittgenstein thought that Moore's papers were some of his best work, but what I think appealed to Wittgenstein was the nature of these Moorean propositions (so-called bedrock propositions) and there role in epistemology. They ground our epistemology in important ways, without them there would be no knowing and no doubting. The language-game of knowing and doubting is necessarily dependent on bedrock beliefs.

We often appeal to our convictions as if they are a form of knowing, especially if they tend to be the convictions of most people. This is one of the reasons why ideology and religious (or any group set of beliefs) beliefs have so much power. The whole group, to one degree or another, is under the spell of their subjective convictions.

[Wittgenstein refers to certainty in two important ways: First, our subjective certainty, which often refers to our convictions, and second, objective certainty, which is just a synonym for "I know."]

This isn't so much about metaphysical claims, unless you are referring to mental states, as it is about the mental state of knowing and the misuse of the concept know. Consider OC 6, "[n]ow, can one enumerate what one knows (like Moore)? Straight off like that, I believe not.--For otherwise the expression "I know" gets misused. And through this misuse a queer and extremely important mental state seems to be revealed." Two things here are important to note, as already mentioned, misuse of the word know and one's mental state (consider OC 42).

"For "I know" seems to describe a state of affairs which guarantees what is known, guarantees it as a fact. One always forgets the expression "I thought I knew (OC 12)."

We often use the phrase "I know" as an expression of our conviction that we know, but this is not an epistemological use of the phrase. This is where there is confusion. An epistemological use of know must have an objective justification, i.e., it must be demonstrated that you indeed do know. Whereas using the phrase "I know" as an expression of one's inner subjective state (feeling or intuition) is not epistemological. The use of "I know" as Moore is using it, is just an expression of a belief, it's not knowledge.

It's in the demonstration of one's knowledge that we often find that what we thought we knew (this is where many are confused about Gettiers e.g.s) is just false. What we believe we know doesn't guarantee anything. Much of what we claim to know is probabilistic, and it can turn out later that some new fact overturns what we believe we know. Hence, I thought I knew. The definition of knowledge as JTB is necessarily the case, but your expression of I know is not necessarily the case. So Wittgenstein's point about the expression "I thought I knew" is an important epistemological point that is also associated with the use of doubt in terms of your claims.

The use of "I know" and "I doubt" is parasitic on the reality in back of our language-games. This is why bedrock beliefs are foundational to knowing and doubting. And it's also why some bedrock beliefs are outside our epistemology. Bedrock beliefs are neither true nor justified, but they are beliefs of a certain kind. Moreover, what's bedrock can change from context to context. For e.g. "I know I have hands" in Moore's context is nonsense or senseless, but in another context it can make perfect sense. Where it does make sense is where it's appropriate to doubt.

"It's not a matter of Moore's knowing that there's a hand there, but rather that we should not understand him if he were to say 'Of course I may be wrong about this". We should ask "What is it like to make such a mistake as that?'--e.g. what's it like to discover that it was a mistake (OC 32)?"

The mistake and the phrase "I thought I knew" are intimately connected.

This seems clearly incorrect, viz., that Moore's statement that he knows he has hands is not a bedrock proposition. In fact, probably all the Moorean propositions given in his two papers are paradigm cases of bedrock propositions (or hinge-propositions). I believe this is a fundamental point made by Witt and most philosophers who study OC.

I don't see how you cannot see that these beliefs form the backdrop that allows all epistemological language to take place. It's similar to saying I don't see how the board, pieces, and rules of chess play a role in the game of chess. There would be no language without our inherited background beliefs, animal beliefs. These bedrock beliefs are crucial to language, and especially to the language-games of epistemology. They solve the infinite regress problem and the problem of circularity. Moorean propositions (hinge-propositions) show just where justification ends, and where doubt falls apart or makes no sense.

(I want to be clear that there are other names associated with these beliefs. The obvious one is hinge-proposition (OC 341), but others come to mind, such as, foundational belief, basic belief, hinge certainties, and animal belief (OC 359).)

I going to answer your question @Fooloso4, but my explanation is also to others who are trying to understand these ideas, so if I say some obvious things keep that in mind.

It's not just the belief about hands, but a whole system of beliefs that falls into the same category. These beliefs make up our inherited background. Moreover, I'm concentrating on those bedrock beliefs that are prelinguistic or animal because of their importance to epistemology and to language itself. Think of these beliefs as ways of acting, i.e., the actions associated with my hands show my belief that I have hands. This is about as primitive or bedrock as you can get because some of our first actions are with our hands. These bedrock beliefs are the ungrounded underpinnings of all the language associated with epistemology. Furthermore, I don't believe they are propositions in the strict sense because they fall outside our language about true and false. This doesn't mean that they can't function as normal propositions in some contexts, it just means that from a bedrock or animal position they are not normal propositions. Loosely speaking, they are states of mind or beliefs reflected primarily in some action. For e.g., like a a dog jumping up and down as it sees its master walking toward the house. These are very primitive beliefs that are prelinguistic or nonlinguistic.

It seems to follow from this that our epistemological language, viz., justification and truth, ends, when butting up against these bedrock beliefs. Included in our epistemological language is the use of the concept doubt. For e.g., "I know X." "How do you know that?" "I don't believe you do know it." - etc. So doubt is closely associated (probably logically associated) with knowing in important ways

The one thing that makes bedrock beliefs stand out is that doubting them makes no sense or is senseless. Why? Because the framework for doubting and knowing is built upon the inherited background of our surroundings. The inherited background is prior to doubting and knowing, i.e., you wouldn't be able to doubt or know without this framework. These concepts grow out of the framework, just as the game of chess grows out of the board and pieces. It's senseless to doubt the very framework that gives rise to the concept doubt. This is why global skepticism is senseless. If you did doubt the framework you would have to doubt the very words you're using.

It seems clear to me that Moore's statement that he knows he has hands is a prime example of a bedrock belief. It's definitely prelinguistic, and it generally cannot be doubted, at least in most contexts without having to doubt the whole of our inherited background.

"What do we do with [these] propositions?" It's a matter of recognizing their special place within language. They are the precursor beliefs to language, and by extension all of the language-games associated with language. So, "What rests on it?" Language rests on it.

I'll stop here for now.

Exactly. Moore's arguments are metaphysically naive. They assume that the true reality of our naively realistic extended world cannot be doubted. These 'bedrock' beliefs you speak of may be pre-linguistic, but they are also pre-philosophical.

If Moore's ideas worked we could falsify Buddhist doctrine simply by pointing out that we have hands. This idea is plainly absurd.

I think some confusion arises here over the difference between believing we truly exist as individuals but doubting we have hands, which would be madness, and doubting the true existence of perceiving individuals and their hands, which is a metaphysically sound position.

(I want to be clear that there are other names associated with these beliefs. The obvious one is hinge-proposition (OC 341)


Are you saying that a bedrock belief (a term that Wittgenstein never used) and a hinge proposition are the same? This is what I take to be the difference. We reach bedrock when there is no further justification. The Earth revolves around the Sun, on the other hand, is a hinge proposition. The claim can be justified and, like a hinge, a great deal hangs from and revolves around it.

It's not just the belief about hands, but a whole system of beliefs that falls into the same category.


"I believe I have hands" is as problematic as "I know I have hands".

I do not think that my dog believes it has paws. The question of their existence does not arise. Consider again OC 476:

Children do not learn that books exist, that armchairs exist, etc.,etc. - they learn to fetch books, sit in armchairs, etc.,etc.
Later, questions about the existence of things do of course arise


Quoting Sam26
Think of these beliefs as ways of acting, i.e., the actions associated with my hands show my belief that I have hands.


Using my hands does not show that I believe I have hands. If, however, I were to move my hands in odds ways, that might show that I believe my hands have magical powers.

Quoting Sam26
The one thing that makes bedrock beliefs stand out is that doubting them makes no sense or is senseless. Why? Because the framework for doubting and knowing is built upon the inherited background of our surroundings. The inherited background is prior to doubting and knowing, i.e., you wouldn't be able to doubt or know without this framework.


Wittgenstein does not limit what he says about bedrock, hinges, inherited background, to what is pre-linguistic:

Consider the following:

96. It might be imagined that some propositions, of the form of empirical propositions, were hardened and functioned as channels for such empirical propositions as were not hardened but fluid; and that this relation altered with time, in that fluid propositions hardened, and hard ones became fluid.
97. The mythology may change back into a state of flux, the river-bed of thoughts may shift. But I distinguish between the movement of the waters on the river-bed and the shift of the bed itself; though there is not a sharp division of the one from the other.

99. And the bank of that river consists partly of hard rock, subject to no alteration or only to an
imperceptible one, partly of sand, which now in one place now in another gets washed away, or deposited.


Compare this to your claim that:

and both Copernicus' and Kant's revolutions. "Fluid propositions hardened, and hard ones became fluid".

Quoting Sam26
So, "What rests on it?" Language rests on it.


When Wittgenstein says:

360. I know that this is my foot. I could not accept any experience as proof to the contrary. - That may be an exclamation; but what follows from it? At least that I shall act with a certainty that knows no doubt, in accordance with my belief.


this might seem to support your claim, but here he is not talking about language but the absence of doubt that if it were present would cause a kind of paralysis.

Language does not rest on things like the proposition that I have hands or feet:

475. I want to regard man here as an animal; as a primitive being to which one grants instinct but not ratiocination. As a creature in a primitive state. Any logic good enough for a primitive means of communication needs no apology from us. Language did not emerge from some kind of ratiocination [Raisonnement].

The term 'hinge' occurs three times. The first:

341. That is to say, the questions that we raise and our doubts depend on the fact that some
propositions are exempt from doubt, are as it were like hinges on which those turn.


Much of the discussion of hinges focuses on doubt and neglects the questions that we raise. He draws our attention to hinges not simply to address the problem of skepticism:

342. That is to say, it belongs to the logic of our scientific investigations that certain things are in deed not doubted.


The idea of hinges replace the ideas of foundationalism.

343. But it isn't that the situation is like this: We just can't investigate everything, and for that reason we are forced to rest content with assumption. If I want the door to turn, the hinges must stay put.


The "door" is our investigations. Rather than resting on foundations they turn on hinges.

Wittgenstein only gives us one example of a hinge:

655. The mathematical proposition has, as it were officially, been given the stamp of
incontestability. I.e.: "Dispute about other things; this is immovable - it is a hinge on which your
dispute can turn."


The mathematical hinge is not pre-linguistic. Neither are others:

298. 'We are quite sure of it' does not mean just that every single person is certain of it, but that we belong to a community which is bound together by science and education.


142. It is not single axioms that strike me as obvious, it is a system in which consequences and premises give one another mutual support.

152. I do not explicitly learn the propositions that stand fast for me. I can discover them
subsequently like the axis around which a body rotates. This axis is not fixed in the sense that
anything holds it fast, but the movement around it determines its immobility.


It is the movement of the work of the community bound together by science and education by which our propositions, beliefs, and knowledge are held fast. The axis is not timeless or immutable, but change is not piecemeal.

305. Here once more there is needed a step like the one taken in relativity theory.

What I'm saying is that our inherited background (that we live in a world with mountains, lakes, clouds, hands, feet, etc), which is not a system of beliefs, but informs what we believe, both linguistically and non-linguistically. So, there are, for example, prelinguistic beliefs (animal beliefs, bedrock beliefs, or basic beliefs), which are shown in our actions (OC 284, 285) alone, viz., digging a hole, using a hand, or even making a primitive tool. I'm not saying that the inherited background is a system of beliefs, but that the inherited background has a strong relation to what we believe, maybe it’s causal. So, if there were no hands, there would be no beliefs that correspond with the action of using our hands. The confusing part is parsing out the difference between the linguistic belief, “This is a hand,” as a statement, with an action alone that reflects a belief, they are quite different, and in many cases prior to language. This latter category of beliefs is foundational to language, which means bedrock (prelinguistic) beliefs are a prerequisite to language. Just as a chess board and pieces are a prerequisite to playing a game of chess.

The point of course is that the inherited background gives rise to bedrock beliefs, and also gives rise to language itself. This means that without the inherited background the language-games of epistemology (justification and truth) wouldn’t get off the ground. In other words, knowing and doubting are necessarily dependent on prelinguistic beliefs. This is why both Moore and the skeptics are wrong. I believe that Wittgenstein identified something that no other philosopher, that I’m aware of, has identified, viz., the foundation of epistemology. The place where justification ends. It’s something prior to any talk of epistemology, something primitive. It’s the limit of epistemology in many respects.

I want to say two final things. First, there are many kinds of bedrock beliefs, not just prelinguistic bedrock beliefs. There are bedrock beliefs that occur in language. For example, the rules of chess are bedrock beliefs, but they are linguistic.

Second, Wittgenstein never edited OC, so whatever one believes about this or that text is speculation (at least in many cases), because we have no idea what Wittgenstein would’ve removed or added to the text. Although I and other philosophers have arrived at very similar conclusions.

There's a pinch of truth in saying language games do not reflect the facts, since the facts, being truths, are a part of the language games around truth. Better perhaps to say that the games are embedded in the world – so the builder's game inherently involves slabs and blocks and cannot be played without them.


I disagree, if I understand you, that facts are truths. They are two different things. Truths are about propositions, and what makes a proposition true is that it reflects or mirrors a fact or state of affairs. I see this as a common mistake, viz., mixing up these two concepts. One could say that the language-game of truth is about facts, and whether a proposition say, "The Earth has one moon," is reflecting a fact.

If we go by the definition of a proposition in logic, then propositions/statements (which are not exactly the same, but close enough for our purposes) are either assertions that something is or is not the case. My e.g., "The Earth has one moon," is an assertion that something is the case. The assertion is making a claim about reality, viz., that there is a state of affairs that corresponds with the assertion. It mirrors reality. If it does mirror reality, then it's true, if not then it's false.

Facts are neither true or false in themselves. It's assertions in the form of propositions/statements that are true or false. To say a fact is true or false is a misunderstanding of the concept. Facts are what make statements true or false. We check our statements against the facts, against the empirical observation that the Earth indeed has one moon. So, no, I'm not claiming there are "untrue facts." there are only untrue or false statements.

And no, I would not say that there are truths cannot be put into propositional form. When we speak of true and false we are necessarily speaking about our claims (propositions/statements).

Reply to Sam26 Oh, I remember now. You take the picture theory seriously. That is, you carry it over into the PI, and presumably into On Certainty.

As a question of exegesis, I remain unconvinced that this is right; But apart from exegesis, the picture theory is too close to what we might call 'conceptual schema' for my liking - after Davidson.

So I don't see the distinction you seem to think sits between the fact that the moon is a satellite of Earth and that the moon is a satellite of Earth. It's as if you would say that "The moon is a satellite of Earth", apart from our language games about the moon and the Earth, or that "The moon is a satellite of Earth" requires no interpretation. On that view, truth is relative to this or that scheme. Better, I think, to give away the duality of scheme (picture) and world, and so "reestablish unmediated touch with the familiar objects whose antics make our sentences and opinions true or false".

When someone's worldview is not possible until some particular state of affairs happens, that particular sequence of events is necessary for that worldview to emerge. That worldview is existentially dependent upon those events. Someone cannot believe that what so and so says at time t1 is true until it is first written by the author and then read by the reader/potential believer...

Here we may have a proposition that acts like a hinge... opening the door of possibility to subsequent beliefs about the proposition... namely, whether or not it is true.

One of the most important ideas that arose out of Wittgenstein's unfinished final notes (On Certainty) is the logical connection between knowledge and doubt (both require a good justification). His emphasis is on the foundational (not the traditional meaning of foundational epistemology) and practical side of epistemology. For Wittgenstein, there seem to be propositions, of a sort (hinge propositions), that consist of very basic beliefs that form the foundation of our claims of knowledge and our expressions of doubt. One such hinge belief, is the belief that "I have hands," which comes from Moore's paper, Proof of the External World. The idea is that certain beliefs arise based on our inherited background of reality. These beliefs (hinge propositions) are not generally justified or true. Their foundational nature gives rise to our epistemological language, i.e., without these very basic beliefs, not only would there not be language but more specifically there would not be epistemological language. Moreover, doubting itself only functions within a particular framework of foundational beliefs, otherwise doubting would lose its meaning. And, just as our epistemological language needs a justification, so does doubting. Without hinge propositions, the whole system of knowledge and doubt would collapse.

This, I believe, is one of the most important ideas to arise out of On Certainty, and it's critical to our understanding of knowledge.

So, what might a theory of knowledge look like for Wittgenstein given the Philosophical Investigations and On Certainty? Of course, this question might be antithetical to Wittgenstein right from the start given his propensity to eschew philosophical theories. So, maybe one could give some guiding principles instead of a theory of knowledge. What might be some guiding Wittgensteinian principles that would hold us in good stead when thinking about knowledge?

1. First and foremost, the inherited background that forms the backdrop for our actions, linguistic and non-linguistic. This is the very framework that allows all of our talk about epistemology and doubt. The context of knowledge and doubt can only occur where there is a framework of foundational beliefs.

2. The formation of our beliefs against this backdrop, and here I'm thinking of Wittgenstein's hinge beliefs, examples include, "I have hands," "There are other minds," "The Earth has existed for a long time," and "I am a being separate from other beings." These beliefs are generally or mostly outside our epistemic language games of knowledge and doubt, which means they fall outside any need to be justified, and any need for them to be referred to as true or false. This seems to be part of the progression of the development of language, i.e., much simpler language games developed before the language games of epistemology.

3. Wittgenstein's view of language games within the context of our cultural forms of life. So, we need to be mindful of the different ways we justify a belief within the context of different language games. We might see, for example, correct reasoning (logic), testimony, linguistic training, sensory experiences, and some other methods or uses of justification within our forms of life. The same applies to the use of the concept of truth.

4. The meaning of these concepts (e.g. justification and truth) needs to be seen under the rubric of Wittgenstein's family resemblance. This helps to keep us from dogmatic definitions.

These are just some of the ideas that might inform my thinking on epistemology.

This is just a cursory view of the subject, but I think it's a good place to start.
Sam26 May 25, 2024 at 13:35 #906556
"The truths which Moore says he knows, are such as, roughly speaking, all of us know, if he knows them [my emphasis] (OC 100)." Of course, Moore does not know what he claims to know, that's part of Wittgenstein's point, and if he does not know them, then he doesn't know they are true, at least not in an epistemological sense of being justified and true. Moore's use of know, even though he believes it to be an epistemological use, is more akin to the use of know as a conviction of what one believes. I believe we can trace Wittgenstein's thinking on this from OC 6 where he points out that Moore is misusing the concept know by pointing to his hand as something he knows. Wittgenstein continues, "And through this misuse a queer and extremely important mental state is revealed." What mental state? The "mental state of conviction." One's conviction can be the same whether it's "knowledge or false belief (OC 42). Moore conflates, as many people do, the use of "I know..." as an expression of a conviction, as opposed to an expression of epistemology (JTB). "Suppose I replaced Moore's 'I know' by 'I am of unshakeable conviction' (OC 86)?"

Yes. This means, in part, that some things that had previously functioned as hinges no longer do, and some that now function as hinges may in time no longer be hinges. When he says that some propositions are exempt from doubt I don't think he means that hinges are atemporal or universal.

Moore conflates, as many people do, the use of "I know..." as an expression of a conviction, as opposed to an expression of epistemology (JTB). "Suppose I replaced Moore's 'I know' by 'I am of unshakeable conviction' (OC 86)?"


It would equally absurd that Moore stand in front of a lecture and say “I, with conviction, have two hands” along with “I know”. The most natural reaction would be to think something is not quite normal here.
Sam26 May 25, 2024 at 19:27 #906624
Reply to Richard B Yes, and this is just what he did, he was in front of people when he expressed his "common sense" view that he knew he had a hand. It's not always as easy to spot the linguistic problem as you might think.
Sam26 May 25, 2024 at 21:44 #906650
"And now if I were to say 'It is my unshakeable conviction that etc.', this means in the present case too that I have not consciously arrived at the conviction by following a particular line of thought, but that it is anchored in all my questions and answers, so anchored that I cannot touch it.

"All testing, all confirmation and disconfirmation of a hypothesis takes place already within a system. And this system is not a more or less arbitrary and doubtful point of departure for all our arguments: no, it belongs to the essence of what we call an argument. The system is not so much the point of departure, as the element in which arguments have their life (OC 103, 105)."

Of course, this refers again to the "inherited background or world picture" that forms the system in which we have our forms of life, language games, and our talk about epistemology. This also includes things that are not only true but also false, which explains why the riverbed of hinges can change. Some hinges are more fixed than others and the changes are more imperceptible.

Now that I think more about it @Fooloso4 there are some hinges that tend to be more immutable. For example, that we are beings that move through space, that I'm a being separate from other beings, that there are other minds, other objects, etc. These may even be necessarily hinges given the laws of the universe. I don't know if I've brought this up before, but maybe that's where you got the idea from. So, there are hinges that range along a kind of scale, some being more or less immutable, and most not being immutable at all.

"And isn't that what Moore wants to say, when he says he knows all these things?--But is his knowing it really what is in question, and not rather that some of these propositions must be solid for us (OC 112)?

Wittgenstein makes the point that some propositions must be solid for us. This is important in terms of what can be rationally doubted within our world picture or inherited background. However, given how broad our world picture is, there will inevitably be false beliefs within it, so what might be a hinge at T1, might not be at T2. In the past, I've mainly focused on hinges that tend not to change or that change very little over time, but Wittgenstein's hinges are much broader in scope. In other words, Wittgenstein's hinges would include actions (linguistic and non-linguistic actions) within any system of belief, even beliefs that are mere myths. There are groups of language games within these various systems that support the system, including epistemological language games. For many religions, belief in God is a hinge. So, we end up with competing systems, with hinges in one system that aren't hinges in another system. What's solid in one system won't be solid in another, and what is doubtable in one system may not be doubtable in another.

That said, certain hinge beliefs ground all of our systems, and these hinge beliefs tend not to change or change very little over time. Again, examples include: "There are other minds," "There are objects," "We have hands," and "The Earth has existed for a long time, etc." These hinges should be in a group of their own because they tend to be the most solid and beyond the reach of any reasonable doubt. They seem to be core hinges.
Sam26 May 26, 2024 at 16:43 #906732
"If you tried to doubt everything you would not get as far as doubting anything. The game of doubting itself presupposes certainty (OC 115)."

What is the certainty that is presupposed? Well, we've been talking about this in the previous posts, viz., the world picture or inherited background. Doubting by its very nature requires a place of certainty. "If you are not certain of any fact, you cannot be certain of the meaning of your words either (OC 114f)."

There is an important point about doubting that's similar to a point raised in earlier posts about knowing, viz., both have uses that point to an inner feeling; Knowing as an expression of conviction and doubting as an expression of intuition or a feeling of unease. Both of these uses are proper, but they are different from the uses of these words in an epistemological context.
Sam26 May 27, 2024 at 18:30 #906924
It seems to me that knowledge and doubt are two sides of the same coin, i.e., you can't have one without the other. "Can one say, 'Where there is no doubt there is no knowledge either (OC 121)."

One could use the word doubt in a way similar to expressing an opinion, viz., there is no justification or very little justification for the doubt, similar to a feeling or intuition. However, just like many of our opinions, it generally carries very little weight. Just as knowledge is superior to mere belief, doubting backed by good reasons or good evidence is superior to a doubt that lacks some form of justification.

Some expressions of doubt are senseless. For example, doubting that there are other persons, grounds for doubt are lacking, everything speaks in favor of there being other persons and nothing against it. What would count as a grounding for such a doubt? "And couldn't we peacefully leave him to doubt it, since it makes no difference at all (OC 120)?"

In one sense , it shouldn’t matter that certain hinge beliefs change slowly, because they do change. The river bank changes much more slowly that the flow of the river, but over long enough periods of time it can be seen to change as continuously as the river. The sense of every hinge proposition you mentioned (“There are other minds," "There are objects," "We have hands," and "The Earth has existed for a long time”) has already been put into question by writers like Husserl and Heidegger. To be clear, they are not claiming that these are false assumptions, but that their assumed intelligibility can be shown to be confused from the vantage of a different starting point.
Sam26 May 27, 2024 at 18:52 #906929
Reply to Joshs I think sometimes we lump hinges into a very large pot, as though they're all the same. However, that there are other objects or other minds isn't going to change, at least as far as I can see.
Sam26 May 27, 2024 at 23:56 #907000
At the bottom of our epistemological use of "I know..." is an ungrounded way of acting, in other words, justification comes to an end. It ends with "...a lot of empirical propositions which we affirm without special testing; propositions, that is, which have a peculiar logical role in the system of our empirical propositions (OC 136)." It seems clear that Wittgenstein is referring to our world picture or our inherited background.

"The propositions, however, which Moore retails as examples of such known truths are indeed interesting. Not because anyone knows their truth, or believes he knows them, but because they all have a similar role in the system of our empirical judgments (OC 137)." It's the role hinges play in our system of judgments that's important, and it's certainly not about whether they're true or false. "We don't for example, arrive at any of them as a result of investigation (OC 138)." If someone wants to say they're true, then I ask, "How do you know they're true?" If you point to some criteria for their justification, then I believe you're missing Wittgenstein's point.
Sam26 May 28, 2024 at 12:37 #907098
"Even if the most trustworthy of men assures me that he knows things are thus and so, this by itself cannot satisfy me that he does know. Only that he believes he knows [my emphasis] (OC 137)."

There is a side issue with knowing that seems to get conflated with what we mean by knowledge (JTB), and what we claim as knowledge. A claim to know, even if one believes that they have the proper justification, doesn't always equate to knowing. This seems obvious, and yet people think that there is some problem with JTB because one can seemingly have a belief that's justified and true, and yet that belief can turn out to be false. Claiming to know is not necessarily knowing. We often believe we know, but later find out that we didn't know. It's simply a difference between one's claims and reality, they don't always match. Moreover, most of what we know is probabilistic and subject to what we think is likely the case, not what is necessarily the case. Given the probabilistic nature of most of our knowledge, it's reasonable to conclude that sometimes what we believe is justified and true, is simply false. This is just part of the nature of our claims and not a flaw in how we define knowledge (JTB). Within any system of beliefs, there will always be some false beliefs, even if we think those beliefs are well-established.
Sam26 May 28, 2024 at 19:49 #907160
"What does this mean: the truth of a proposition is certain (OC 193)?"

"With the word 'certain' we express complete conviction, the total absence of doubt, and thereby we seek to convince other people. That is subjective certainty.

"But when is something objectively certain? When a mistake is not possible. But what kind of possibility is that? Mustn't mistake be logically excluded (OC 194)?"

Wittgenstein uses certain in two different senses in OC, subjectively certain, as an expression of a conviction or feeling about a belief, and objectively certain, which is another way of expressing a piece of knowledge as JTB. So, certainty and knowledge both have their subjective and objective counterparts, and they are often confused.

OC 194 brings up a very interesting point, i.e., the tendency is to say, "I know...," and here one thinks one is using know in the epistemological sense (as Moore's does), as a guarantee that one knows, as if a mistake is not possible. However, if a claim to know is in itself knowledge, it would seem that knowing would lose its force, it would be akin to a conviction, opinion, or intuition. Knowledge must stand up to the doubt, "How is it that you know?" Note that with a mere belief, one might respond to the question "Why do you believe that?" with the answer "I just do," and that's acceptable as a mere belief; but a claim to knowledge as JTB requires more, it requires that the belief be justified and true. And of course, Wittgenstein in challenging Moore's use by asking what would count as a justification for "I know this is a hand." Wittgenstein is telling us that Moore's use of "I know..." is akin to an expression of a conviction, not objective knowledge as Moore thinks it is. Of course, this brings us full circle, viz., that the propositions that Moore retails as knowledge hold a special place within our world picture. Moore doesn't know, in his context, what he thinks he knows.

There is a lot to unpack here, and I've just scratched the surface.

"The reason why the use of the expression "true or false" has something misleading about it is that it is like saying "it tallies with the facts or it doesn't", and the very thing that is in question is what "tallying" is here (OC 199)."

It seems very easy to say that a proposition is true because it tallies, mirrors, corresponds, etc. with the facts, but in Moore's case what does it mean? Moreover, what does it mean for any proposition to tally with the facts? There must be a way of deciding for or against a proposition (OC 198). Some propositions are determined to be justified and true based on what method of justification we're using, for example, logic, sensory experience, testimony, linguistic training, etc. To determine how most propositions are true we use one of these justification methods. The question though, for Wittgenstein has to do with certain kinds of propositions, Moorean propositions, which hold a special place in our system of beliefs, viz., the grounding of our epistemological talk of justification and truth. If justification comes to an end with hinges, then tallying loses its meaning with hinges, which seems to be why the question "What is tallying with the facts?"

"Really 'The proposition is either true or false' only means that it must be possible to decide for or against it. But this does not say what the ground for such a decision is like (OC 200)."

My interpretation is that the ground refers back to the world picture or inherited background, i.e., it grounds our very talk of justification and truth. Moore doesn't see that bedrock doesn't need grounding; it is the ground. Indeed, most of us don't see it. This solves the infinite regress problem, viz., where does justification end?
Sam26 May 29, 2024 at 16:16 #907352
"Giving grounds [justification], however, justifying the evidence, comes to an end;--but the end is not certain propositions' striking us immediately as true, i.e., it is not a kind of seeing on our part; it is our acting [non-linguistic], which lies at the bottom of our language game (OC 204)."

Wittgenstein's ideas seem to build on each other. At the bottom, i.e. the grounding or the world picture, then we have our actions (non-linguistic actions) within that grounding. On top of this comes a primitive language, then more sophisticated language games like knowing and doubting. Knowing and doubting come much later, it's parasitic on the world picture.

But recall that Wittgenstein regarded the ordinary meaning of "to know" to not imply infallibility, in the sense that even if a fact P necessarily implies another fact Q, "knowing that P" does not necessarily imply Q.

This stems from his epistemic consideration that in a literal sense nothing is knowable in the sense demanded by a philosopher. And yet he appreciated that everyone including himself ordinarily use the verb "to know" all the time. Therefore he concluded that the ordinary meaning of "to know" isn't an insinuation of ideal knowledge.

If Moore's knowledge of his hands is interpreted in that light, then had Moore later discovered that he didn't actually have hands, his discovery wouldn't contradict his earlier ordinary claim to "know that he had hands"

Philosophers don't, as a general rule, hold to the notion that knowledge implies infallibility if that's what you're implying. Inductive reasoning is probabilistic, so any knowledge gained by inductive reasoning is not infallible by definition. I think Wittgenstein's point is that some uses of "I know.." are not epistemological as in Moore's case, at least that's part of Witts point.

I do not think Wittgenstein regards knowing and doubting as sophisticated language games. Both knowing and doubting in their nascent forms are primitive.

3. If e.g. someone says "I don't know if there's a hand here" he might be told "Look closer". - This possibility of satisfying oneself is part of the language-game. Is one of its essential features.


7. My life shows that I know or am certain that there is a chair over there, or a door, and so on. - I tell a friend e.g. "Take that chair over there", "Shut the door", etc. etc.


41. ... But "I know where you touched my arm" is right.


160. The child learns by believing the adult. Doubt comes after belief.


354. Doubting and non-doubting behavior. There is the first only if there is the second.


510 .. It is just like directly taking hold of something, as I take hold of my towel without having doubts.


These examples of looking, sitting, feeling, believing, acting are all "non-linguistic".

Reply to Fooloso4 I'm saying that knowing and doubting as epistemological uses are more sophisticated language games. Knowing and doubting does not occur as an epistemological language game when speaking of hinge beliefs, generally. So, if you're speaking in terms of primitive man there is no knowing and doubting epistemologically. And, even if we're talking about modern man and their language games hinge beliefs also fall outside epistemological considerations.

OC 3 is just an example of where it might be proper to doubt and how we might satisfy that doubt. Moore's use is not such a case.

7 is referring to a subjective knowing and certainty. That's my interpretation.

Reply to Fooloso4 I see, not knowing and doubting, but believing and doubting as more inextricably tied. The problem I have with the idea that knowing involves uncertainty or defeasibility, is that it seems weird, inconsistent or incoherent. to say that you know, but that you could be mistaken. It also seems strange to say that we could know, despite not knowing that we know, which seems to be a corollary of JTB. What exactly constitutes justification seems underdetermined.

So, I would say knowing comes into play when we, leaving aside considerations that evolve out of indulging artificially manufactured faux-doubt, cannot be wrong concerning what we know. In the primeval scenario, for example, you see the tiger on the path in front of you—you know the tiger is there. Alternatively, you hear a tiger-like growl somewhere in the bushes and you believe there is a tiger there, but there is some room for doubt.

So, going back to the 'Moore' example, I would agree with him that knows he has hands.

Science is a form of knowing in a participatory and a practical sense. We know the world, in the sense of participating in it, via science. It is practical too in the that it is a practice, a know-how. Propositional knowledge though, it seems to me, requires observation. I know I have hands because I can see them, observe myself using them and so on. I know it is raining when I am out and I feel the rain on my body and see the drops falling. In those kinds of cases, of which there are countlessly many in our lives, we cannot be mistaken, barring faux-doubt and bizarre thought-experiment scenarios, which I don't believe deserve our concern.

Science uses the same justification methods we all do, logic (inductive and deductive reasoning), sensory experience (observation), and testimony (peer reviewed papers, lectures, etc). It's just that science is generally more precise with these methods than the general public. Most knowledge in general is practical, not just science. Moreover, science draws conclusions based on whatever method of justification it's using, and these conclusions are in the form of propositions. If science presents a theory based on experiments or mathematical models, then someone probably believes the conclusions are either true or false. If they believe they're true or false, they're using propositions. Most all of what we know is in the form of propositions.

Knowledge can come in the form of a skill (know how) or in the form of a belief. Mostly when we talk about knowledge we're talking about beliefs not knowledge as a skill (like riding a bike or conducting skillful experiments). Although skills overlap with knowledge as a belief.

A claim to have good reason to believe X is partly what we mean by know. Good reasons are how we justify many of our beliefs and why we make claims that a proposition is true. It is a claim to know.

Part of Wittgenstein's argument against Moore is that we don't know we have hands. The hinge belief that we have hands is just part of the world picture we have along with a million other things, but it's not knowledge. I believe Witt is correct about this.

I see, not knowing and doubting, but believing and doubting as more inextricably tied.


The top part of the lower section of Plato's divided line is pistis. The Greek term can be translated as belief, trust, persuasion, confidence, and as in the NT faith. In other words, what is not doubted. That is not to say what is indubitable. The philosopher raises doubts about things that are ordinarily not doubted. His concern is the truth of things. The move from opinion to knowledge is by way of doubt or skepticism (skeptis - to inquire). There is, however, also knowledge of the arts (techne) and Socrates own knowledge of Eros, from which his knowledge of ignorance arises.

With regard to knowledge and doubt in On Certainty:

6. Now, can one enumerate what one knows (like Moore)? Straight off like that, I believe not. - For otherwise the expression "I know" gets misused. And through this misuse a queer and extremely
important mental state seems to be revealed.


What is this mental state?

12. - For "I know" seems to describe a state of affairs which guarantees what is known, guarantees it as a fact. One always forgets the expression "I thought I knew".


When Moore says he knows he has hands, this does not refute the skeptic.

8. The difference between the concept of 'knowing' and the concept of 'being certain' isn't of any great importance at all, except where "I know" is meant to mean: I can't be wrong.


Wittgenstein is not denying that Moore knows he has hands. He is rejecting Moore's misuse of the term.

7. My life shows that I know or am certain that there is a chair over there, or a door, and so on. - I tell a friend e.g. "Take that chair over there", "Shut the door", etc. etc.


I might also tell a friend to move his hand. No question arises as to whether he has a hand or whether he knows he has a hand. He knows he has a hand. I know he has a hand. But this will not satisfy the radical skeptic.

Further, although rejects radical skepticism he does hold a more measured and moderate skepticism.

651. I cannot be making a mistake about 12x12 being 144. And now one cannot contrast
mathematical certainty with the relative uncertainty of empirical propositions.


Empirical propositions do not have the certainty of mathematics. In the Tractatus he says:

6.36311 It is an hypothesis that the sun will rise tomorrow: and this means that we do not know whether it will rise.


We may not doubt whether the sun will rise tomorrow, but whether or not it will is a contingent rather than necessary fact.

I think Wittgenstein in "On Certainty" is exploring this distinction between contingent and necessary. In some ways in seems to be approaching a view of Quine where our most fossilized propositions can be up for revision. Consider the following:

213 "Our empirical propositions' do not form a homogeneous mass"

217 "If someone supposed that all our calculations were uncertain and that we could rely on none of them (justifying himself by saying that mistakes are always possible) perhaps we would say he was crazy. But can we say he is in error? Does he not just react differently? We rely on calculations, he does't, we are sure, he isn't."

167 "It is clear that our empirical propositions do not all have the same status, since one can lay down such a proposition and turn it from an empirical proposition into a norm description. Think of chemical investigations. Lavoisier makes experiments with substances in his laboratory and now he concludes that this and that take place when there is burning. He does not say that it might happen otherwise another time. He has got hold of a definite world picture - not of course one that he invited: he learned it as a child. I say world picture and not hypothesis, because it is the matter-of-course foundation for his research and as such also goes unmentioned."

447 "Compare with this 12X12 = 144. Here too we don't say "perhaps". For, in so far as this proposition rests on our not miscounting or miscalculating and on our senses not deceiving us as we calculate, both proportions, the arithmetical one and the physical one, are on the same level. I want to say: The physical game is just as certain as the arithmetical. But this can be misunderstood. My remark is a logical and not a psychological one."

613 "If I now say "I know that the water in the kettle on the gas flame will not freeze but boil", I seem to be as justified in this "I know" as I am in any. "If I know anything I know this".- Or do I know with greater certainty that the person opposite me is my old friend so and so? And how does that compare with the proportion that I am seeing with two eyes and shall see them if I look in the glass?-I don't know confidently what I am to answer here.-But still there is a different between cases. If the water one the gas freezes, of course I shall be as astonished as can be, but I assume some factor I don't know of, and perhaps leave the matter to physicists to judge. But what could make me doubt whether this person here is N.N, whom I have know for years? Here a doubt would seem to drag everything with it and plunge it into chaos."

I would say he was exploring this distinction between contingent/necessary and seeing that some empirical proposition can be held as firmly as mathematical propositions, and even these firmly held mathematical propositions we can imagine folk reacting to them differently where notions of "right/incorrect" seem to lose any sense.

What is this mental state?


The mental state Wittgenstein seems to be referring to is the mental state of conviction. Moore's use of "I know..." is just that, a conviction of certainty. In OC 42 Witt refers to what is expressed by tone of voice and gestures (expressing a conviction), which fits Moore's use of "I know..." as he pronounces "I know this is a hand," by raising his hand before an audience. It's not an epistemological use of the words "I know..." where one is expressing a justified true belief.

In OC 7 Witt points out that our lives show (by our actions) these kinds of hinge beliefs, for example, by getting the chair or shutting the door. These are the subjective certainties of our world picture, which is how we act in the world. It's a misuse of know in the epistemological sense, we don't justify these kinds of beliefs, which is what Moore is trying to do and why Witt is criticizing his use of know. If OC 7 isn't about one's inner certainty, then it would be making the same mistake Moore makes.

Just to reiterate, there's a difference between one's inner subjective certainty (or using know as an expression of a conviction) and the epistemological use of "I know..." as an expression of objective certainty (knowledge). Witt uses know and certain in both ways, and it's important to distinguish between the two.

"Can one say: "Where there is no doubt there is no knowledge either (OC 121)." The doubt, in the sense of challenging one's knowledge claim, is essential to what it means to have objective knowledge. Otherwise, we end up with pronouncements like Moore's, as if the pronouncement itself is enough. It also seems to be why Wittgenstein says in OC 4 to consider the negation of these kinds of propositions. If the negation doesn't make sense, then it's not epistemological it's a hinge. The epistemological use of "I know..." has to make sense when considering its negation. If it doesn't then it's just an expression of a hinge belief. It's the doubt that separates the epistemological from the hinges. In the former the doubt makes sense, in the latter it doesn't.

Reply to Richard B

I don't know Quine so can't comment on the comparison.



613 is interesting. First, he says he is justified in knowing that the water will boil. If it doesn't he assumes there will be an explanation, some factor he is unaware of. It does not threaten his picture of the world. The whole of physics has not come into question. But if this is not N.N. then everything is plunged into chaos. If this is not his old friend then everything he knows becomes uncertain.

447 seems to challenge 651 regarding the relative uncertainty of empirical propositions. But is my certainty that this is a hand the result of empirical observation?

125. If a blind man were to ask me "Have you got two hands?" I should not make sure by looking.
If I were to have any doubt of it, then I don't know why I should trust my eyes. For why shouldn't I
test my eyes by looking to find out whether I see my two hands? What is to be tested by what?

If I sit in the chair it is objectively certain that there is a chair. My sitting in it is all the justification that is required. But the requirement for justification is out of place. This does not mean that it is not an epistemological use of 'know'. It means that you are imposing the very requirements on the term 'know' that Wittgenstein is arguing against. If there are two different ways in which the term is used, it is the difference between the way it is ordinarily used and the mistaken sense in which it is used to mean that one who knows can't be wrong. There is no mental state of knowing that guarantees its correctness.

If so, what are we doing here doing practically infinite hermeneutics? Is that philosophically sound, or is it overmining? If an author tries to confound with too many questions, is that bad faith arguing, clever philosophizing, or "showing"? How do we know which is which besides preference in style, or what others say is supposed to count as preferential style? Can one actually put in more effort than an author in philosophizing a point of the author? If so, why? If that's the case, might it be more prudent to put the effort into taking what one learns and developing one's own ideas and philosophy instead of endless hermeneutics of really trying to "get" an obscure text?

Part II of the PI is often an overlooked, less quoted part of the book. But I believe it hints at the many directions Wittgenstein was possibly exploring. Lets take a look at some:

In these passages, it is not just analyzing the use of words that Wittgenstein is exploring.

Part II, section I, "One can imagine an animal angry frightened, unhappy, happy, startled. But hopeful? And why not? A dog believes his master will come the day after tomorrow? And what can he not do here? How do I do it? How am I supposed to answer this? Can only those hope who can talk? Only those who masters the use of a language. That is to say, the phenomena of hope are modes of this complicated form of life." I think here Wittgenstein is pondering the relationship between primitive reactions and complex form of life, is he not asking questions and looking for an explanation, and not just wanting to describe the language of hope?

Part II section ii, In saying "When I heard this word, it meant.... to me" one refers to a point in time and to a way of using the word. (Of course, it is this combination that we fail to grasp.) Again Wittgenstein is going beyond just the analysis of the use of a word, but looking also at the relation of reference and time.

Part II section v, "It is like the relation: physical object-sense impression. Here we have two different language games and a complicated relation between them-If you try to reduce their relation to a simple formula you go wrong." Here a fascinating discussion between two different philosophical outlooks one founded on a naturalistic view and the other a more introspective view?

Part II section x "How did we ever come to use such an expression as "I believe.." Did we at some time become aware of phenomenon (of belief)? Did we observe ourselves and other people and so discover belief?" A very interesting question, but will the answer come from analysis of the use of words?

Part II section xi "I shall call the following figure, derived from Jastrow, the duck-rabbit. It can be seen as a rabbit's head or as a duck's. And I must distinguish between the 'continuous seeing' of an aspect and the 'dawning' of an aspect." What is Wittgenstein doing in this passage? In trying to describe a picture, is he exploring how we borrow from our language to describe what seems to be a rather interestingly unique experience and to get another human being to see it as I do?

Lastly, Part II section xii "If the formation of concepts can be explain by facts of nature, would we not be interested, not in grammar, but rather in that in nature which is the basis of grammar? - Our interest certainly includes the correspondence between concepts and very general fact of nature. (Such fact facts as mostly do not strike us because of their generality.) But our interest does not fall back upon these possible causes of the formation of concepts; we are not doing natural science, nor yet natural history-since we also invent fictitious natural history for our purposes.

I am not saying; If such and such facts of nature were different people would have different concepts (in the sense of hypothesis). But: if anyone believe certain concepts are absolutely the correct ones, and that having different ones would mean not realizing something that we realize-then let him imagine certain very general facts of nature to be different from what we are used to, and the formation of concepts different from the usual ones will become intelligible to him."

I think this is the most interesting direction Wittgenstein is considering here. The philosophy of concept formation. This is not about describing how we use our words, but exploring how we come to formulate our concepts.
Sam26 June 01, 2024 at 13:53 #907949
"When Moore says he knows such and such, he is really enumerating a lot of empirical propositions which we affirm without special testing; propositions, that is, which have a peculiar logical role in the system of our empirical propositions (OC 136)."

The propositions Moore claims to know, viz., those listed in his paper A Defense of Common Sense are the propositions Wittgenstein is referring to. Besides the most commonly used of Moore's statements "I know this is a hand," others include, "There exists at present a living human body, which is my body," and (paraphrasing) "There are other human bodies of the same class that have lived on Earth and have had many different experiences." These are the propositions Wittgenstein is referring to as empirical propositions that we affirm without special testing. In other words, we don't normally need a justification (epistemologically) for these beliefs. These are hinge propositions (I prefer to call them hinge beliefs), and they fulfill the logical role of being bedrock, foundational, or basic to our whole system of epistemological language games. It's where justification ends (no special testing required). Why? Because special testing or justification gets its life from these hinge beliefs. Not only do these beliefs give life to our epistemological language games, but they also give life to the language games of doubting. Such beliefs also reflect an ungrounded way of acting, which is at the core of our world picture or inherited background.

And where it's proper to give a justification for Moore's propositions, i.e., the exceptions, then these propositions are not hinges. So, they can function as proper propositions in certain contexts, but not generally. As I've mentioned elsewhere, and where I've expanded on what I think follows from OC, is that these beliefs at their core are pre-linguistic beliefs, shown in our actions.

It's not only Moore's use of know that is problematic, but saying these hinge beliefs are generally true is also problematic in similar ways.

I agree with the significance of Part ll and that Wittgenstein goes far beyond the analyzing the use of words. What I am wondering about is the idea of taking philosophy in new and interesting directions. There are scattered comments about him seeing his work as preparatory for what others will do.

Sam26 June 01, 2024 at 19:07 #907973
The most difficult part of Wittgenstein's epistemology is to understand the groundlessness of our epistemology. The whole system is predicated on arational beliefs, and this is what is so different about Wittgenstein's approach to knowing and doubting. I believe that if you don't see this, you're missing the core of what Wittgenstein is saying.

"Must I not begin to trust somewhere? That is to say: somewhere I must begin with not-doubting; and that is not, so to speak, hasting but excusable: it is part of judging (OC 150)."

One last tantalizing passage from Wittgenstein and his thinking about concept formation. From Culture and Value:

"Life can educate one to a belief in God. And experiences too are what bring this about; but I don't mean visions and other forms of sense experience which show us the 'existence of this being', but, e.g. sufferings of various sorts. These neither show us God in the way a sense impression shows us an object, not do they give rise to conjectures about him. Experiences, thoughts, - life can force this concept on us. So perhaps it is similar to the concept of 'object'.

This is not about pondering the use of the word "God", but pondering life itself.

In his Notebooks 1914-1916 he says:

The meaning of life, i.e. the meaning of the world, we can call God.

To believe in a God means to understand the question about the meaning of life.

To believe in a God means to see that the facts of the world are not the end of the matter.

To believe in God means to see that life has a meaning.

However this may be, at any rate we are in a certain sense dependent,
and what we are dependent on we can call God.

In this sense God would simply be fate, or, what is the same thing: The world-which is independent of our will.

I can make myself independent of fate.

There are two godheads: the world and my independent I.

"I should like to say: Moore does not know what he asserts he knows, but it stands fast for him, as also for me; regarding it as absolutely solid is part of our method of doubt and enquiry (OC 151)."

It seems clear that Wittgenstein is not only saying Moore's use of know is a misuse, but also that it's not knowledge. The beliefs (arational and hinge beliefs) Moore claims to know are the bedrock, foundation, and solid "...part of our method of doubt and enquiry." It forms a whole system of beliefs that "...characterize the way [we] judge, characterize the nature of judgment (OC 149)." The "nature of judgment" includes our epistemological language games and our language games of doubting. This means that justification and truth are an outgrowth of what stands fast, which is why, generally speaking, hinge beliefs are not justified and not true or false. How can this be? There is no how or why it's simply how we act. "Why do I not satisfy myself that I have two feet when I want to get up from my chair? There is no why. I simply don't. This is how I act (OC 148)."

Does this mean that the system of our judgments doesn't change, of course not, it just means that at any given point in time, there is a system of judgment that we don't question. Some of the beliefs in the system will remain unchanged and some will be removed, and others added, but the system will always be there as part of our bedrock beliefs. That there is a system of judgment is unchanging, it can't be otherwise. There is a limit to reason, to justification and truth, and it's an arational system of beliefs.

Do I think Wittgenstein is correct? Absolutely, and it changes the nature of epistemology, and moreover, it shows the limits of epistemology. I believe many philosophers and thinkers have overlooked Wittgenstein's final remarks.

Sam26 June 02, 2024 at 16:21 #908041
What is the nature of a hinge belief? What if someone's world picture includes belief in God as a hinge belief? Or, what if another world picture excludes belief in God as part of their hinge beliefs? Can we just decide whether this or that belief is a hinge? And, if for example, belief in God is a hinge, then there is no need to justify the belief as true or false, since they're arational beliefs. Does Wittgenstein address this problem, or do we end up with conflicting hinge beliefs? Dr. Duncan Pritchard often mentions this in his papers and his lectures. I believe Wittgenstein does address this issue.

That depends on what is being claimed. If someone were to say that they believe in God, I cannot prove them wrong. If, however, they claim that like Abraham God commands him to sacrifice his son then their belief in God and what God commands would need justification.

239. I believe that every human being has two human parents; but Catholics believe that Jesus only had a human mother. And other people might believe that there are human beings with no parents, and give no credence to all the contrary evidence. Catholics believe as well that in certain
circumstances a wafer completely changes its nature, and at the same time that all evidence proves
the contrary. And so if Moore said "I know that this is wine and not blood", Catholics would
contradict him.


If a priest takes transubstantiated wine and attempts to donate it to a blood bank, whether his belief is true or false is in question.

243. One says "I know" when one is ready to give compelling grounds. "I know" relates to a
possibility of demonstrating the truth. Whether someone knows something can come to light,
assuming that he is convinced of it.
But if what he believes is of such a kind that the grounds that he can give are no surer than his
assertion, then he cannot say that he knows what he believes.


The believer will insist that the wine has truly become blood. When chemical analysis confirms that it is wine the believer will reject the science. This is something he will say he knows. Something beyond scientific understanding. What we might regard as compelling ground may be something he thinks needs to be corrected by the word of God. There are deeper truths, he might say, that science is blind to.

336. But what men consider reasonable or unreasonable alters. At certain periods men find
reasonable what at other periods they found unreasonable. And vice-versa.
But is there no objective character here?

The philosopher raises doubts about things that are ordinarily not doubted. His concern is the truth of things. The move from opinion to knowledge is by way of doubt or skepticism (skeptis - to inquire). There is, however, also knowledge of the arts (techne) and Socrates own knowledge of Eros, from which his knowledge of ignorance arises.


Yes, the philosopher questions accepted beliefs, doubts them and subjects them to examination to try to determine whether they are actually true. But there are many beliefs the truth of which is not determinable.

Techne, or know-how is a different category of knowledge than 'knowledge as beleif" it seems to me, it is rather 'knowledge as ability'.

With regard to knowledge and doubt in On Certainty:

6. Now, can one enumerate what one knows (like Moore)? Straight off like that, I believe not. - For otherwise the expression "I know" gets misused. And through this misuse a queer and extremely
important mental state seems to be revealed.

What is this mental state?

12. - For "I know" seems to describe a state of affairs which guarantees what is known, guarantees it as a fact. One always forgets the expression "I thought I knew".

When Moore says he knows he has hands, this does not refute the skeptic.


I don't see the problem with saying that you know you have hands, or that you know any of the things that can be directly seen to be the case. I agree that this does not defeat radical skepticism, but I think the latter defeats itself, because it is trying to empty knowledge of all contexts, free it from all any any contexts whatsoever, and render it absolute.

About things which one claims to know, but which one cannot be certain about, I think when one says 'I know" one is always really saying "I think I know", which as I said earlier amounts to "I believe I have good reason to think I know this". But if we want to cast this as being more than merely belief (as opposed to the knowledge we have of those things of which we can be certain) this opens up the strange notion that we could know without knowing that know.

Empirical propositions do not have the certainty of mathematics. In the Tractatus he says:

6.36311 It is an hypothesis that the sun will rise tomorrow: and this means that we do not know whether it will rise.

We may not doubt whether the sun will rise tomorrow, but whether or not it will is a contingent rather than necessary fact.


I agree with that, insofar as it refers to inductively derived propositions, such as 'the Sun will rise tomorrow". If I am out in the rain and say, "it is raining", on the other hand; if that statement is to be counted as a proposition, then it would seem to be as certain as any mathematical truth. On the other hand, such an utterance might not be counted as a proposition, but merely as an observation. But it seems to me that what we observe and experience we most certainly know.

If science presents a theory based on experiments or mathematical models, then someone probably believes the conclusions are either true or false. If they believe they're true or false, they're using propositions. Most all of what we know is in the form of propositions.


They believe the theory is true or false, so they do not know it be one or the other. On the other hand, in a different sense, theories are forms of 'know-how' in that they enable us to see the world in different ways, make novel predictions and so on. But that is not propositional knowledge it seems to me.

A claim to have good reason to believe X is partly what we mean by know. Good reasons are how we justify many of our beliefs and why we make claims that a proposition is true. It is a claim to know.

I'm not saying that people don't use it as a hinge. I'm saying it's not a proper hinge. There could be some beliefs within any system, even ones that contain myths, that are viewed as hinges. What makes a belief a proper hinge is that it doesn't make sense to doubt it (what does making sense here mean?). Doubting that there is a God makes perfect sense. It's nothing like doubting there are objects, or hands, or minds, etc. People may act as though it's a hinge (belief in God), which shows they believe it's a hinge, that's all.

There seem to be certain core beliefs that most systems of belief recognize as hinge. In other words, there are overlapping systems of belief that contain the same core beliefs (hinges), but they also contain other beliefs, considered hinges, but not recognized as such within those other systems. So, you end up with systems with competing hinge beliefs. Sorting this out happens over time.

Of course they're convinced, which is why they consider it a hinge.

One could argue based on some of Witt's remarks that there are hinges of different kinds and that what's considered a hinge at T1, might not be at T2. We acknowledge that hinges change and that some of these changes are more pronounced than others. Wittgenstein doesn't use some of my terminology, but that's because I'm trying to expand on Witt's ideas. I'm not saying that all of my remarks can be supported by passages in OC or anywhere else. My remarks are a combination of my conclusions based on passages in OC, and my expansion of his ideas whether they agree or not.

Some may have as part of their hinge beliefs that sacrificing a child will yield more crops. So, are hinge beliefs relative to some system of beliefs? Yes. But this doesn't mean we aren't capable of sorting out what I call "proper" hinge beliefs from "improper" ones. The question becomes, are there good reasons to reject or doubt what they consider a hinge belief? If there are good reasons to doubt, then it's not a hinge. The fact that we're constantly arguing over, belief in God, shows that at least some doubting is warranted, if not most or even all doubts are warranted. It's certainly not like doubting that there are objects that exist in space. I can't understand what a doubt about the existence of objects would even entail. However, I can and do understand doubting the existence of God; and even though my e.g. at the beginning of this paragraph is more extreme, the same point holds.

If I had to characterize “hinge proposition” I would say it is one where a human accepts it and its logical consequences as a whole. This acceptance would not be because it strikes us as true but that it has some pragmatic effect on us that when we put them into practice it brings value and meaning to our lives.

Take example A and definition number 1. Does that strike one as true? You could probably make the case that it is plain nonsense by itself. But if one accepts the definition and moves forward with it, the fruitfulness may be seen. And the same goes example B.

I'm not sure that we have the same view on hinge beliefs. It depends on what you mean by "logical consequences" of a hinge belief. There is no doubt that hinge beliefs have consequences in our acts (linguistic and non-linguistic), and that there is a logical scaffolding to our belief systems. However, we have different views of hinges if you use "logical consequences" as a synonym for correct reasoning (inductive and deductive). Also, hinge beliefs don't depend on some practical effect.

I definitely want to use “logical consequences” somewhat loosely here, meaning that Euclid and Anselm may not be using some shared universal logic here. Lastly, what I am emphasizing is these “hinge propositions” are a choice, you either use them or you don’t, and whether you use them or not may be because there is a value to them. Whether one can articulate the value is another story. I am sure there are these “hinge propositions” hidden in the background of every day life that most do not question and/or aware of.

Yep, belief/propositions have consequences when one uses them, I do not see how one escapes this existential fact about living in the world. If one goes on doubting one has a hand because of intellectual reasoning, yet keeps using the word in practice like everyone else, what was the point of doubting? Alternatively, if one chooses not to use the word “hands” because of some radical doubt, I pity one’s chances in surviving our world.

There is no fixed point that serves as the basis for beliefs and judgments. The system of judgments varies from time to time and place to place and to some extend from person to person.

My interpretation of OC comes closest to Danièle Moyal-Sharrock (University of Hertfordshire). I arrived at my interpretation quite independent of her or any other philosopher. My idea of pre-linguistic beliefs, which I've often compared with animal beliefs is similar to comments she made about the animal in OC (OC 359). I believe, as does she that Wittgenstein solves the infinite regress problem in epistemology, which is one of his contributions to the subject of epistemology. As she says, "it puts a logical stop to infinite regress."

"Wittgenstein's revolutionary insight in On Certainty is that what philosophers have
traditionally called 'basic beliefs' – those beliefs that all knowledge must ultimately be based
on – cannot, on pain of infinite regress, themselves be propositional beliefs. They are really
animal or unreflective ways of acting which, once formulated (e.g. by philosophers), look like
propositional beliefs. It is this misleading appearance that leads philosophers to believe that at
the foundation of thought is yet more thought. For, though they often resemble empirical
conclusions, basic certainties (or 'hinge certainties' or 'hinges' – as I shall also call them
following Wittgenstein's hinge metaphor [OC 341]) constitute the ungrounded,
nonpropositional underpinning of knowledge, not its object. In thus situating the foundation
of knowledge in nonreflective certainties that manifest themselves as ways of acting,
Wittgenstein has found the place where justification comes to an end, and solved the regress
problem of basic beliefs – and, in passing, shown the logical impossibility of radical or global
scepticism. I believe that this is a groundbreaking achievement for philosophy – worthy of
calling On Certainty Wittgenstein's 'third masterpiece' (The Animal in Epistemology:
Wittgenstein's Enactivist Solution to the Problem of Regress, by Daniele Moyal-Sharrock)."

Interesting question, not sure I can answer that from a personal psychological perspective. Additionally you bring in “truth” which adds an additional complexity. Nevertheless, I will give it a go in some general fashion.

Since you bring in the mix scientific theories, I will go with that theme. Is Newtonian and Einsteinian physics knowledge? I think it would be difficult to argue with a scientist to say that it was not. I presume you would argue that Einsteinian physics proved Newtonian physics false. But this sounds strange because Newtonian physics works very well in many circumstances. Our knowledge of Newtonian physics allows us to make many predictions that prove useful in going about in our daily lives. But instead of using a word like “false” should we not say “less accurate in prediction of measurable properties in situations at high speeds”?

Lastly, lets take a look at your definition of belief/knowledge in relation to Newtonian/Einsteinian physics: “if there can be any doubt that it is true, then we don’t know it either”. What is the nature of this doubt? That you could imagine otherwise?, For example, I can imagine something faster than the speed of light therefore Einsteinian physics is only a belief not knowledge.

One reason I have often heard is that you would need an infinite amount of energy to move a mass to the speed of light that makes it impossible, and no one knows where to get an infinite amount of energy. So, we are waiting around to figure it out and that is why "we don't know for sure." But I think when we say "we don't know for sure" and "we don't believe nothing can...", or even "we know nothing can..." may be inappropriate expressions to use in this case. The reason being that this notion of the speed of light is intertwined with our notions of time, space, and change. For instance, if something is traveling at the speed of light, objects from that perspective are not experiencing time (I like to think of a observer moving at the speed of light away from a clock where the light ray hitting the hands of the clock never to reach the observer and so are frozen in time.). So, it is not that no object can move faster than the speed of light, but fundamental notions of time and space lose all meaning pass these limits. So, to say we believe or know nothing can travel faster than the speed of light, is more like saying, we can't give meaning to our notion of time and space beyond this limit. There is nothing to believe, know or even doubt. We may think we are imagining possible hypothetical possibilities, but that is not the case, these theories are limiting not only what can be physically achieve, but even what can be sensible imagined at a conceptual level. Now does this mean we can't redefine speed/time/space is some manner to our liking? Of course not, and maybe we can redefine these ideas in such a way that when we utter the words "faster than the speed of light.", they have a clear meaning. But this does not mean that terms like time/space in this new paradigm will resemble anything from the previous paradigm.

This is what I think Wittgenstein gets at a little in "On Certainty" when he said:

167 "It is clear that our empirical propositions do not all have the same status, since one can lay down such a proposition and turn it from an empirical proposition into a norm description. Think of chemical investigations. Lavoisier makes experiments with substances in his laboratory and now he concludes that this and that take place when there is burning. He does not say that it might happen otherwise another time. He has got hold of a definite world picture - not of course one that he invited: he learned it as a child. I say world picture and not hypothesis, because it is the matter-of-course foundation for his research and as such also goes unmentioned."

That we would need an infinite amount of energy is a central plank of the theory, but the theory might turn out to be wrong. Or there might be things we are not aware of that travel faster than light. The rest of what you say also consists of a number of corollaries of the theory, and this begs the question.

I'm not saying the theory is likely to turn out to be wrong, and I would agree that we have very little reason to believe it is wrong. On account of having little reason to believe it is wrong we believe it is right, but I don't count that as knowledge, but would rather call it belief.

In another sense, as per the quote from Wittgenstein, the scientific paradigms within which scientists work are not questioned, and are the background against which questions are asked and answered, and I think this qualifies them, insofar as they are methodologies or ways of working, as being knowledge in the sense of know-how.

A few points.

Foremost, OC is not a coherent argument for a specific point of view. It would be an error then to attempt to interpret it in a way that is both complete and consistent. The work is incomplete, and so need not be consistent.

As part of W.'s notes from the last few months of his life, it is instead a window into the progress of this thinking. It shows us his approach in practice. The method of OC is far more important and interesting than any conclusions that it might be thought to draw.

OC hangs on a grand tension W. sees in Moore's "here is a hand".
Quoting Proof of an External World by G. E. Moore
It seems to me that, so far from its being true, as Kant declares to be his opinion, that there is only one possible proof of the existence of things outside of us, namely the one which he has given, I can now give a large number of different proofs, each of which is a perfectly rigorous proof; and that at many other times I have been in a position to give many others. I can prove now, for instance, that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, ‘Here is one hand’, and adding, as I make a certain gesture with the left, ‘and here is another’. And if, by doing this, I have proved ipso facto the existence of external things, you will all see that I can also do it now in numbers of other ways: there is no need to multiply examples.

Moore is replying to Kant, as is clear, and presumably the objection is to the argument that we never have access to the thing-in-itself. Moore's reply is to shake the thing in Kant's face.

Wittgenstein had great sympathy for Moore's view. Whereof one cannot speak, thereof one must remain silent; one can say nothing about the thing-in-itself; therefore leave it out of our conversation.

Yet W. was unsatisfied with Moore's response. OC is Wittgenstein working through the issues raised by that dissatisfaction.

Of course silence is only a small part of the tale. There is also the world - all that is the case; and as well, there is what we might do about it. We evict questions of meaning, looking instead to questions of use, and so trade silence for action.

Hence the appeal of hand waving.

In so far as Moore shows that there are hands, W. is on side. In so far as Moore knows that there are hands, W. remains perplexed.

While he shows that Moore's use of "know" in "I know this is my hand" is problematic, Wittgenstein pretty much agreed with the argument Moore presents against idealism and scepticism. "Here is a hand" shows that there is stuff around us to be dealt with, providing a foundation, a setting for certainty. There have to be slabs in order to engage in the builder's game, hands for there to be had shakes, and certainty within which to express doubt.

"Here is a hand" - we behave in this way, we set up a way of doing things that takes "This is a hand" as granted, as enacted in the way we do things.

And notice that it's "we" and not "I" - the confidence that this is a hand comes from communal agreement, not from the perception of a homunculus or solipsistic conviction. It is inherently a public activity.

The special place of some propositions is that bringing them into question is bringing in to question the game in which they are played - how do you recognise that this card is an ace, or that the standard Metre is a metre long, or that a dollar coin is worth one dollar.

In the Investigations Wittgenstein sets out two ways of "following a rule"; the first is seen in setting out the rule, interpreting it, translating it and so on; the second,
PI §201:...there is a way of grasping a rule which is not an interpretation, but which is exhibited in what we call "obeying the rule" and "going against it" in actual cases.
The rule is enacted, not stated.

This focus on enacting a rule is the engine behind treating use rather than meaning, and behind the private language argument. A rule may well be stated, perhaps in order to pass it on to others, or for purposes of regulation. It is not that the rule is unstatable, although any statement might well be incomplete - hence family resemblance. Following and going against a rule is recognisable by a community, and forms the way in which a community functions - their "form of life". To state a rule is to set out its propositional content, what following or going against the rule consists in.

This informs the parts of PI now often referred to as W's philosophy of psychology. Following or going against a rule allows us to implement practices, ways of doing things, that have a social role despite in a sense not having an empirical grounding. So you cannot feel my pain, nor tell if I see red where you see blue, nor infer my beliefs indubitably from my actions, but despite this we have a functional - usable - language around pain, sensation, belief and so on.

One of the marvellous things about PI is the number of philosophical tools with which it presents us - beetles, family resemblances, private language, and so on. These are the tools used in On Certainty

For Wittgenstein, Moore's paper touches on many of the issues raised in PI. In On Certainty W. is taking the ideas of PI and applying them to notions of knowledge and certainty, exploring how a consistent account might be formulated.

But On Certainty does not present us with a "Third Wittgenstein".

Recent work in these forums has tended to focus on either the Tractatus or on On Certainty. The Investigations has dropped somewhat from view. The Tractatus was unsatisfactory, obliging Wittgenstein to reenter philosophy, and giving us the Investigations. Reading the Tractatus without referring to the Investigations will lead one to misunderstand the progress and errors in W's work. One must read each in the light of the other.

If the Tractatus had been complete and consistent, there would have been no need for the Investigations. It is a mistake therefore to treat the Tractatus as complete and consistent. This error is apparent in some threads hereabouts.

It is also a mistake to try to understand On Certainty apart from the philosophical tools presented in PI. Doing so has led some recent scholarship to supposing that because a rule is sometimes unstated, it must thereby be unstatable; that a rule may have no propositional content. In contrast, the considerations of the PI show that an unstatable rule can have no claim to being thought of as a rule. It is instead perhaps a sentiment or a habit.

The remedy for this misunderstanding of On Certainty lie in Philosophical Investigations.

I still think Moore and Wittgenstein did not sufficiently provide an alternative to Kant's project. Moore simply resorts back to what is sensory, but Kant's whole point was to refute Hume, and posit that there was a mechanism whereby the mind must interpret the immediate sensory experience into something intelligible. By doing this, it is always "the hand as it appears to us" and not simply "hand as it is in-itself". Moore didn't refute that with this famous "Here is a hand. Here is another."

Wittgenstein, in turn, seemed to just sideline the question as to social practice rather than how it is that the mind can turn raw sensory information into coherent thoughts. Cognitive science and anthropology already go a step beyond Wittgenstein by reincorporating the learning aspects with cognitive structures in the brain and evolutionary biology. So I am not sure either of these two attempts provide much of a response to Kant. If anything, it highlights that what Kant's project was about was central to understanding how humans gain knowledge of the world. You cannot just bypass the questions Kant poses by fiat by mere showing (Moore) or by turning it into a completely social phenomenon (later Wittgenstein).

Reply to Banno

What is it according to the Tractatus that we must remain silent about? The answer is, the sense (Sinn) of the world, as opposed to the sense of things in the world (6.41). Matters of value, of ethics and aesthetics as opposed to the accidental facts of what happens in the world. Things in the world, both as they are in themselves and as they are for us phenomenally, are not things about which one must remain silent.

I won't get into the odd notion of one's own hand as an external thing in itself. In any case, I don't think it has anything to do with the problems of On Certainty.

Quoting Banno

Wittgenstein does not evict questions of meaning. 'Meaning' has different senses that in German can correspond to Sinn and Bedeutung. The meaning of a word, how it is used, is not the same as a word being meaningful or having significance or importance. What is meaningful, matters of value, of ethics and aesthetics, are not matters of the use of terms. We might see from someone's actions that something has meaning for them, but the action does not explain the meaning of the action.

But On Certainty does not present us with a "Third Wittgenstein".


I agree, although for reasons that perhaps differ from your own. I see it as a development of such things as the notion of a form of life, as part of the shift away from propositions as foundational.

From OC:

In the beginning was the deed.
(OC 402)

But that means I want to conceive it as something that lies beyond being justified or
unjustified; as it were, as something animal.
(OC 359)

I want to regard man here as an animal; as a primitive being to which one grants instinct but
not ratiocination. As a creature in a primitive state. Any logic good enough for a primitive means of
communication needs no apology from us. Language did not emerge from some kind of
ratiocination.
(OC 475)

The rule is determined by the practice rather than the practice being determined by the rule.

See:

26. But can it be seen from a rule what circumstances logically exclude a mistake in the
employment of rules of calculation?
What use is a rule to us here? Mightn't we (in turn) go wrong in applying it?


And:

OC 139. Not only rules, but also examples are needed for establishing a practice. Our rules leave loopholes open, and the practice has to speak for itself.


OC 140. We do not learn the practice of making empirical judgments by learning rules: we are taught judgments and their connexion with other judgments. A totality of judgments is made plausible to us.

What are the grounds for doubt? What are the grounds for knowing? Maybe part of the confusion lies in the fact that we can imagine situations were we can doubt such propositions. However, can we doubt the propositions Moore is using, and can we doubt them in Moore's contexts?


Language games end where pure phenomena begin. But this can be doubted as well: for how is it "pure phenomenon," escapes being a contextual "game" constituent itself? It doesn't, and Derrida was right about the "trace" which puts all that lies outside of the trace under erasure, under metaphysical erasure. So close to the Tractatus here, no? The world is mystical and ethics transcendental and Wittgenstein is sounding like the mystic Russell said he was.
But as I see it, there is no way to reconcile "the world" and language beyond this: it is a pervasive "doubt" that yields an ontology of, if you can stand it, the cloud of unknowing, the mystical underpinning of hermeneutics. The cogito and its object stand in a mystical relation.
Rorty was said that it has never been shown how anything "out there" (this under erasure) can get in here (the head's brain thing). A fascinating insight, so simply put, even as one is deeply pondering Descartes, missing this obvious fact, that there is nothing epistemic about causality. It is not doubt that rules this thinking, but hermeneutics and contextuality.
Banno June 13, 2024 at 22:23 #910098
Postulating a "hand as it is in-itself" gets nowhere. Such a hand cannot enter into our discussions, cannot be used to pick things up, and "drops out of consideration as irrelevant."

There is more to this, though, in that postulating a "hand as it is in-itself" already posits a hand, already separating hands from non-hands, and so is already indulging in interpretation. It suffers a deep circularity.

But that's more Hegel than Wittgenstein. Hegel and Wittgenstein might find agreement in noticing that Kant's attempt to reach outside of reason to the thing-in-itself, is itself reasoning. We are always, unavoidably, immersed in the Logos.

Frankly I do not expect some here to agree with this, as there are quite fundamental things going on in Wittgenstein that some folk appear unable, perhaps temporarily, to apprehend. But that they cannot see it should not be taken as reason to shut down discussion of Wittgenstein. There are would-be gatekeepers on either side of the gate.

Since 'it is always "the hand as it appears to us"', silence is what remains for "the hand as it is in itself". Notice again that it is "the hand as it appears to us", not "the hand as it appears to me".

Others might agree that there is more to silence than mere inactivity. W's response to the second war was not to theorise, but to take on a menial job in a hospital - to act. Whereof one must be silent, thereof one must nevertheless act, appreciate, mourn, and get on with life. Waving one's hand in Kant's face is a silent act.

Hopefully in silence, baby sucks its fist, unawares of being a baby , or having a fist . That this is a fist arises as the baby takes its place in its family, in its linguistic community.

Trouble is, of course, that some things refused to sit neatly as either a thing in the world or a thing outside it. As W. showed in Remarks on Colour, an explanation of colour must take into account the way in which communities manage to get on with purchasing tins of paint despite their philosopher being unable to pin down what it is that is the same about red seen here, and seen there, and for you, and I. We need to ask not just what is it that the Tractatus must remain silent about. We need to go the step further and see why that silence needed to be broken by the Investigations.

"Here is a hand" is a hinge proposition. It has the structure of a statement and it has a truth value. That it is true need not be justified by other facts, need not be seen as a consequence of ratiocination; but, like something's being red or beautiful, this being a hand involves both how the world is and how we employ language.

The move from the Tractatus to the investigations is from removing complexity to accepting it as part of being human.

Aware?

There is some unpacking to do here. They use their hand, perhaps; but is that all there is to being aware of one's hands? The game takes place without mention of hands, as you say - so are the players aware of their hands? If the block falls on the apprentice's hand, they might become aware; perhaps in doing first aid. Again they become aware of the hand as it enters into their interactions.

Nice example, though. The baby and the builder are not unaware of their hands, any more than aware of their hands. "A dog cannot lie. Neither can he be sincere. A dog may be expecting his master to come. Why can't he be expecting him to come next Wednesday? Is it because he doesn't have language?"

...on Wittgenstein’s view, while chess is essentially a game for two players, this does not exclude the possibility of playing it against oneself provided such solitary games are not regarded as paradigm instances of chess. Similarly, he can claim that language is essentially social, but still allow the possibility of exceptions provided these are peripheral cases.


We can take this further, though, if we leave exegesis and look at the broader context. Which comes first, meaning or mental content? Will we follow Sellers in taking mental content as deriving from linguistic meaning? Or Grice in taking linguistic meaning as deriving from mental content? Until there is more by way of evidence, it might be better to follow Davidson, and presume that mental content and linguistic meaning are interdependent.

Which of these three Wittgenstein might have accepted must now remain conjectural. His role was to show that rules have a place here, but are of themselves insufficient.


Quoting Fooloso4

There are deep differences between the aesthetics of the Tractatus and the Investigations:
Quoting Wittgenstein's Aesthetics (SEP)
For now, at this stage of Wittgenstein's development, where the complexity-accepting stance of the later Philosophical Investigations (1958) and other work is unearthing and uprooting the philosophical presuppositions of the simplification-seeking earlier work, examples themselves have priority as indispensable instruments in the struggle to free ourselves of misconception in the aesthetic realm. . And these examples, given due and detailed attention, will exhibit a context-sensitive particularity that makes generalized pronouncements hovering high above the ground of that detail look otiose, inattentive, or, more bluntly, just a plain falsification of experience. What remains is not, then—and this is an idea Wittgenstein's auditors must themselves have struggled with in those rooms in Cambridge, as many still do today—another theory built upon now stronger foundations, but rather a clear view of our multiform aesthetic practices. Wittgenstein, in his mature, later work, did not generate a theory of language, of mind, or of mathematics. He generated, rather, a vast body of work perhaps united only in its therapeutic and intricately labored search for conceptual clarification. One sees the same philosophical aspiration driving his foray into aesthetics.


So again, it is perhaps a mistake to see any of Wittgenstein's writings as complete, and hence an exegetical error to attempt to set out a coherent and complete picture.

Sam26 June 15, 2024 at 01:33 #910292
It seems that language games are only possible if we don’t question certain facts, and whether these facts are true or false. Here I’m referring to hinge propositions (or hinge beliefs). Moreover, I don’t believe that our grammar is conditioned by certain empirical facts. This is not to say that facts don’t play a role in our grammar, it just means that whatever the relationship is, it plays a lesser role. I say lesser role given the autonomous nature of language. There seems to be no doubt that there is some relationship between empirical facts and our grammar (Wittgensteinian grammar). Saying that facts condition our grammar, as per Moyal-Sharrock, seems to diminish the autonomous nature of grammar, especially since it’s grammar that determines what we mean by fact, object, and reality. So, our grammar presupposes these concepts, but it’s not independent of reality.

It seems clear that certain facts of reality, those that we don’t normally doubt, create the surface that allows language games to be played. Similar to a chess board providing the surface area for a chess game. So, the language game of asserting and denying, viz., being true or false rests on Wittgenstein’s hinge propositions (or hinge beliefs), and thus, any talk of epistemology (justification and truth) rests on hinges. Another way to say it is that our methodology of evaluating propositions rests on hinges.

Part of the problem concerns the conflation of hinge beliefs with our normal beliefs (or you could say hinge propositions with normal propositions), they are quite different and have different functions. So, the language game of epistemology is only possible if we never question certain facts. Just as playing a game of chess involves never questioning the rules of chess. The logical role of hinges is that of being beyond doubt and therefore beyond truth and falsity. To bring in the idea that hinge beliefs are true and false is to miss one of the core points of On Certainty. It’s like trying to shove a square peg into a round hole.

It is not that grammar determines facts:

Do I want to say, then, that certain facts are favorable to the formation of certain concepts; or again unfavorable? And does experience teach us this? It is a fact of experience that human beings alter their concepts, exchange them for others when they learn new facts; when in this way what was formerly important to them becomes unimportant, and vice versa.

There is a difference between using one's hand to touch or move something, and being aware that it is one's hand one is using to touch or move something. Just as a dog may be expecting his master to come, but not to come next Wednesday. Much of our world is constructed within and by language, and the associated mental content.

Which is why the accounts of Sellars, Grice and Davidson are directly relevant. Davidson addresses the issue by setting out a triangulation between one's hand, one's beliefs about one's hand, and one's language concerning one's hand. There is a recursive relation here, not a simplistic causal sequence from hand to concept to word. We build on our beliefs and on our language in constructing our social world.

Using one's hand is not physical so much as animal. Hence:
OC:357. One might say: " 'I know' expresses comfortable certainty, not the certainty that is still struggling."
358. Now I would like to regard this certainty, not as something akin to hastiness or superficiality, but as a form of life. (That is very badly expressed and probably badly thought as well.)
359. But that means I want to conceive it as something that lies beyond being justified or unjustified; as it were, as something animal.

For Wittgenstein aesthetics and ethics are shown in performance, so that expressions of ethical or aesthetic preference are all but irrelevant. One shows one's appreciation for a tailor by wearing his cloths.

The word "hinge" is used only three times in OC. Perhaps its importance has been exaggerated. But let's consider this:
OC:340. We know, with the same certainty with which we believe any mathematical proposition, how the letters A and B are pronounced, what the colour of human blood is called, that other human beings have blood and call it "blood".
341. That is to say, the questions that we raise and our doubts depend on the fact that some propositions are exempt from doubt, are as it were like hinges on which those turn.
342. That is to say, it belongs to the logic of our scientific investigations that certain things are in deed not doubted.

It is very clear here that it is certain propositions that are exempt from doubt. The game can only be played if certain propositions are, not exempt from truth or falsity, but treated as being true. I also think it worthy of note that "hinge belief" does not occur in OC.

This is not an aspect of these propositions, but an aspect of the game. One can of course move the Bishop down a column, but in so doing one ceases to be playing chess. A proposition's being a hinge is a role it takes on within a language game.

Hence "language games are only possible if we don’t question certain facts" as a part of that language game.

Specifically, that some empirical fact - "Here is a hand" - is to be counted as a hinge is in virtue of its place within the game, not in virtue of its empirical content.

So I'd be cautious about suggesting that language games rest on hinge propositions, as if the hinge were something apart from the door. "If I want the door to turn, the hinges must stay put"; without the hinge the door is a plank filling a hole in the wall. Again, being a hinge is a role within a language game, not a aspect of beliefs or propositions apart from the language game.

My interpretation is that there is something foundational here, viz., that some propositions are foundational to our claims of knowledge or our claims of doubt. When you reach bedrock no part of the foundational structure is stronger.


I agree with you, there are "strong foundational" propositions; even ones which we can conventionally settle upon as having nothing preceding it but the "truth". But doubt that it would be possible to "trace back" and "locate" the factual foundational proposition which is derived from no other. Because that proposition would consist of words; in whichever language, each word the strong and foundational, would likely have been derived from several, if not many preceding words. And before words, in some cases, grunts or gestures (though I accept that may be going too far).

And if you're referring to what the phenomenological crowd calls noumena, or something like, those too are, no matter how reasoned tge argument, just too vague to confidently rest at "no preceding concept."

I do not know if I have wandered far from Wittgenstein or any expectations of orthodoxy. So I apologize.

My point is, all of our propositions are weak, there is no accessible bedrock, beyond speculation, follwed by convention; reasoned, but still, speculation (since all of the mechanisms constructing reason, too, are now remote, far removed from that initial representation of the truth.

"'I know that I am a human being.' In order to see how unclear the sense of this proposition is, consider its negation. At most it might be taken to mean 'I know I have the organs of a human'.


I think skepticism is the inevitable position, and philosophy, and philosophy forum, and this discussion persists because we are l intuitively skeptical in spite of intermittent settlements called belief knowledge or certainty.

That it is inevitable can be seen even in the language in propositions "I know I am x because" No you don't. We all so called know that everything we so called know is subject to adjustment. So even the language of the non-skeptic betrays skepticism is already built in. That temporary settlement we call knowledge, or certainty is nothing more than a functional belief necessitated by the way tge whole aystem--Mind--moves. There would be no human Mind or a very different one if tge mechanisms for belief didn't evolve. Or, in W terms, belief is a built-in "rule" of play.

To say I know I have two hands already implies that it is accepted by you, nothing more can ever be said. True so called certain can never be about a thing; it can only be the thing.

I can be certain that I am, only in the being, not in the knowing.

I do not think that one can use their hand to touch or move something without being aware that it is one's hand that one is using.

One cannot move something with one's hand without using one's hand. But one can certainly - and indeed usually does - use one's hand without directing one's conscious awareness to one's hand...

Indeed, doing so is often counterproductive. Think of carrying a tray of drinks - one focuses on the glasses in order not to spill the contents; focusing on one's hands will not help. One is aware of the object one is moving, rather than of one's hands.

Go back to the post that initiated this somewhat tedious discussion:
Quoting Banno
"Here is a hand" - we behave in this way, we set up a way of doing things that takes "This is a hand" as granted, as enacted in the way we do things.

And notice that it's "we" and not "I" - the confidence that this is a hand comes from communal agreement, not from the perception of a homunculus or solipsistic conviction. It is inherently a public activity.

Notice that it is the confidence that this is a hand that I am pointing to, not the confidence shown in using the hand. The baby may of course make use of its hand without awareness that what it is making use of is a hand.

Being aware that this is a hand stands seperate from making use of the hand.

WIfe's cat habitually shows us that its food or water is empty. These serve as a part of the world that the is common to us and the cat. The cat broke its lower left canine yesterday, in such a way that it was still attached to its jaw, but projecting forward out of its mouth. Wife noticed that the cat would go to eat or drink, and jerk back at the discomfort. The cat repeatedly took us over to the full food or water bowl, as if to say that the bowl needed fixing, that the food was hurting - apparently unaware that it has teeth as such. It very practically made use of the common features of the world, the bowls, in order to make us aware of its tooth. Whether the cat is aware that it has teeth, as distinct from being aware of how to bite or pull out its claws, is moot.

Quoting Fooloso4
How is being aware of one's hand just like a dog expecting his master but not expecting him to come next Wednesday?

Notice the misrepresentation of what I have said - being aware that "this is a hand" is like being aware that the dog's master will come next Wednesday in that both require a level of language acquisition. Being aware that "this is a hand" is not the same as making use of a hand to perform some task.

So it seems to me that you are "arguing" about points on which we mostly agree. It's more of argument for the sake of argument than any substantial difference. Might leave this chat there, since it would be more interesting to consider the substantial account offered by Danièle Moyal-Sharrock.

This is my theory:

We think of our interaction with the world as if it's a conversation we're having with it. When you look for your sunglasses, you're asking the world a question: where are my glasses? Then you listen for the world's responses. Those responses are what we call propositions. You hear the world say: They're on the kitchen table. If it turns out that it is your glasses there, it's a true proposition. True propositions are where you understood the world correctly. But if those are your friend's glasses, and you were mistaken, then it was a false proposition. You didn't hear the world correctly.

So when you see your hand and say this is a hand, you're repeating what world said. You're expressing a proposition. Then you ask yourself, is there any way I could have misheard the world's voice in this case? I guess some people say you couldn't have. But this line of thought is searching for cases where you can't mishear the world.

If we bring up the brain in vat scenario and attest that we may not be having a conversation with a world, but rather our own thoughts or some such, that's a tangential issue. It doesn't undermine the fact that having discussions with the world is primal.

I also think it worthy of note that "hinge belief" does not occur in OC.


All knowledge is about beliefs (unless we're talking about knowledge as a skill), and from the start of OC Witt talks about what Moore considers knowledge. Witt then goes on to explain that Moore's propositions, which are about what he believes to be the case (what he knows), have a special role. All the propositions, even those referred to as hinges, bedrock, foundational, etc., are about beliefs, which is why I refer to them as hinge beliefs. Indeed, Witt doesn't use that wording, but I think it's clear, at least in my mind, that hinge propositions (Moore's propositions) are about beliefs of a certain kind.

The difference between what some of you are doing in this thread and what I'm doing is that I'm trying to go beyond OC to where it might lead. For me, it's not always about getting the correct interpretation, because as you and I have mentioned many times these notes were never finished. We can argue endlessly over interpretations, which I find pointless (at least to some degree). What I think is important is getting a handle on Moore's propositions as endpoints (where justification ends) for epistemology.

Also, although Witt never talked about classifying hinges, I do think there are different kinds of hinges given a particular context or language game.

We think of our interaction with the world as if it's a conversation we're having with it.

I don't, but you might. Perhaps one advantage of so doing is that it displays how integral language is to our interactions with the world.

Again, that something counts as a hinge is not a general characteristic. One can set up circumstances where "This is a hand" does not function as a hinge. Counting as a hinge, being indubitable, is a role within a language game; something one does with a sentence.

Your last paragraph stand, I think. The vatted brain is still involved in the various discussions that make up the world, even if that world is a simulation.


Reply to Sam26 The salient point I would make for you is that a game can only be played if some propositions are, not exempt from truth or falsity, but treated as being true.

I suspect saying that this or that belief is a hinge might mislead one into forgetting that the it is a hinge only within the games we play, the things we are doing - perhaps into thinking that it is a hinge always and in all circumstances.

So consider again the wider context of 13:3, one of the mentions of 'hinge"...
OC:340. We know, with the same certainty with which we believe any mathematical proposition, how the letters A and B are pronounced, what the colour of human blood is called, that other human beings have blood and call it "blood".
341. That is to say, the questions that we raise and our doubts depend on the fact that some propositions are exempt from doubt, are as it were like hinges on which those turn.
342. That is to say, it belongs to the logic of our scientific investigations that certain things are in deed not doubted.
343. But it isn't that the situation is like this: We just can't investigate everything, and for that reason we are forced to rest content with assumption. If I want the door to turn, the hinges must stay put.
344. My life consists in my being content to accept many things.
345. If I ask someone "what colour do you see at the moment?", in order, that is, to learn what colour is there at the moment, I cannot at the same time question whether the person I ask understands English, whether he wants to take me in, whether my own memory is not leaving me in the lurch as to the names of colours, and so on.
346. When I am trying to mate someone in chess, I cannot have doubts about the pieces perhaps changing places of themselves and my memory simultaneously playing tricks on me so that I don't notice.

Notice how this ends by listing prerequisites for asking about a colour and playing chess. These are the what is held firm in order for the game to be played, the task to be done: 'Here is a hand".

As for types of hinges, there are I think at least two*. There are things that must be in place in the world in order for the game to occur - slabs and blocks for the builder, apples for the shop keeper, hands for Moore, and so on. There are also what might be called constitutive statements - getting the ball in the net counts as getting a goal; this wall counts as dividing my property from yours... See Searle.

There may be other candidates for taking on being undoubted for the sake of getting things done.

I sometimes find @Fooloso4's comments unhelpful because they offer a criticism - often quite minor - without an apparent alternative or solution. But there is also the more general point I've made about the exegesis of a text such as On Certainty, that as it is a work in progress, there is no reason to expect it to be coherent and consistent. What counts in such a text is exactly what you, Sam, have described yourself as doing - going beyond the text to see where it leads. Wittgenstein is not Aristotle. Not a body of rules to be assimilated, but a set of tools to be made use of.

Anyway, my notes on Moyal-Sharrock would now make an essay, if they could be put into some sort of coherence. I more or less agree with their text, all except the conclusion. I suspect Moyal-Sharrock is arguing against the likes of Fodor and in so doing has placed too much emphasis on belief as trust rather than belief as an attitude. This is where I would like to take this conversation next.

*Well, prima facie, at least two. It is worth considering if "This is a block" and "This is a hand" ought be analysed as "This counts as a block" and "This counts as a hand".

Edit: Oh, and another point about §340. Notice that the things listed - the colour of blood, that it is called "blood", how "a" and "b" are pronounced, mathematical propositions - are routine, mundane. So many of the examples given in OC have this characteristic - my address, that I am dreaming, that this is a tree... Calling these "hinges" perhaps gives them too much celebrity; they are a commonplace aspect of our use of words. Not so special.

I think your account is missing this: that propositions are not first or second person accounts. They're in third person. They aren't necessarily spoken by any human at any time. I think this is where Austin's usefulness ends.

It's a tricky point, but it's this: when you repeat a proposition, you're essentially repeating what you think the world would say. Expressing a proposition implies a world who (in our imaginations) can speak.

So you can't use any particular proposition to prove that there is a world. It doesn't work that way.

As I understand it, interpretation is about the ideas in play. It differs from theology, or at least to some forms of theology, in that it does not assume the truth of those ideas. The ideas remain in play. It is about becoming clear as to what those idea are. It is all too common, for both "professionals" and amateurs alike, to make claims about what those ideas are for the author in question and then arguing for or against those claims. It is one thing to take an idea and run with it, it is quite another to attempt to understand the author. I do not think there is anything wrong with the former. Ideas can take on a life of their own, but I believe that some thinkers can teach us things and if we are to learn from them then we would do well to attend to what they say and take care to understand them. In a thread on a particular work by a particular author what that author says and means remains in question.

Thinking for yourself is not something that occurs in isolation. To the extent it does, we suffer from the isolation that comes from imagining we are original thinkers.

This is exactly what Wittgenstein is referring to in the remark:

I ought to be no more than a mirror, in which my reader can see his own thinking with all its deformities so that, helped in this way, he can put it right.
(CV 18)

Many get this backwards. They recognize their own thinking in what he says, and believe he is in agreement with them.

If I am not quite sure how I should start a book, this is because I am still unclear about something, For I should like to start with the original data of philosophy, written and spoken sentences, with books as it were.
And here we come on the difficulty of "all is in flux". Perhaps that is the very point at which to start.
(CV 8)

Thinking for myself, I agree with Wittgenstein. When as a freshman in college I took a course is something called "philosophy", something I knew nothing about. I arrogantly assumed that I, from the vantage point of the advances in knowledge since these dusty old books were written, had nothing to learn from them and much that I could teach them. Having had the good fortune of being introduced to primary works of philosophy and, more importantly, how to read them, I came to see just how wrong I was.

Over the years I have heard many people claim to be original thinkers. None of them are.

To believe your own thought, to believe that what is true for you in your private heart is true for all men, -- that is genius.


If I come to experience "the divine spirit" then perhaps I will accept that there is such a thing. Until I receive "a divine wisdom" I will think for myself and not think such a thing true based on what Emerson or anyone else may claim, and will not "accept the place divine providence has found for ..." me. He says:

And we are now men, and must accept in the highest mind the same transcendent destiny ...


Why must I accept that? Is trusting myself really the same as trusting transcendent destiny? Thinking for myself I do not trust it. But my trust in myself is tempered by my awareness of my ignorance of such things.

I would say that what we are dealing with aren't propositions in the normal sense or Wittgenstein wouldn't have singled them out as hinge, bedrock, foundational, etc. I never thought they were exempt from truth or falsity. I said that generally hinges are not thought of as true or false. there are exceptions, and Wittgenstein gave examples of those exceptions.

"Treated as true" is an interesting phrase. How does this differ from normal propositions that we treat as true? Do we treat hinges as true, but they're not really true? Or, maybe we act as though they're true, like the rules of chess. "It's true that I have a hand" seems as odd as saying "I know I have a hand," again generally speaking because of the exceptions.

I've brought up the idea that there are pre-linguistic hinges (e.g. animal beliefs) that seem clearly to have no association with truth or falsity unless you bring in the linguistic concepts of true and false. This is also why I think there are different categories of hinges. It seems that this is implied in OC. It's "the deed" that comes first, i.e., how we act that shows the hinge.

I agree.

Much of what I've been doing is thinking out loud. So, my analysis is partly an exegesis, which is difficult because we don't know which parts of OC Witt would have left in or out of a final draft, and partly where I think his thoughts lead.

There's a lot in that, most notably the notion that a proposition is something apart from the utterances that instantiate it.

Let's contrast two ideas. There is a similarity between "It is raining" and "Il pleut". How do we analyse this similarity? Here are two ways of thinking about this. The first is that there is something that both "It is raining" and "Il pleut" stand for or refer to, and that thing is the proposition present in "It is raining" and "Il pleut". The second is that the use to which we put "It is raining" is much the same as the use to which we put "Il pleut", and so the similarity between them is about their place in our language games.

In the first, an abstract entity is invoked, and immediately followed by all sorts of philosophical investigations - what is the nature of this abstract entity, the proposition? Is it real, is it a Platonic form, is it an eternal statement, and so on. Thousands of years of misguided verbiage ensue.

In the second, we might simply have a translation: "Il pleut" is true IFF it is raining, and no abstract entity is invoked.

If we see things in the first way, it seems legitimate to supose, as you do, "that the same P can be expressed by a lot of different methods", and to supose that the true form of a proposition is to be found in a disembodied third person account.

If we see things the second way, we simply have a group of statements with a functional similarity - in French or English, as in the first or second person.

Now of course there are all sorts of issues to be dealt with in seeing the issue in this second way, but amongst them is not the ontological status of propositions.

And if we see things in the second way, it remains that we might on occasions speak metaphorically of the proposition expressed by two differing statements, but we should baulk at going looking for that proposition. No need to hunt the Snark.

Quoting Sam26
I would say that what we are dealing with aren't propositions in the normal sense...

I think they are exactly that: normal propositions. They do not differ in their structure from any other proposition. Where they differ is in the place they take in the things we do with words.

Hence "treated as...". "Here is a hand" might be treated as indubitable in Moore's lecture, but perhaps not in Frankenstein's laboratory.

Look at the wording of this:
OC:655. The mathematical proposition has, as it were officially, been given the stamp of incontestability. I.e.: "Dispute about other things; this is immovable - it is a hinge on which your dispute can turn."
"...has, as it were officially, been given the stamp of incontestability". Being outside of contention is a role taken on in the way we make use of mathematical propositions. It is given to the statement by the way we make use of it.

I've sometimes toyed with the idea that any proposition could take on the role of being indubitable, in a suitably constructed language game - in much the same way, after Feyerabend, that an observation statement can be discounted as a falsification if suitable auxiliary hypotheses are invoked. Here considerations go off into the nature of modality, and the sort of propositions that might be true in all circumstances. I think one is left with little more than the desire to be consistent in how one expresses oneself.

In OC Wittgenstein spends much effort in looking for propositions that are indubitable in all circumstances, but in all circumstances finds situations in which a proposition might be doubted:
OC:658. The question "But mightn't you be in the grip of a delusion now and perhaps later find this out?" - might also be raised as an objection to any proposition of the multiplication tables.

Not at all. I said a proposition is what we imagine the world would say. If you notice, my account of propositions is very similar to Russell's. He believed a true proposition is simply a state of the world. But that left him confused as to how propositions can be false. My solution: we're descendants of people who thought the world could talk. That heritage is the origin of the concept of propositions.

Reply to Sam26 Yep.

So, to make a start on Understanding On Certainty, Moyal-Sharrock, the contention there is something like that hinges are not belief-that, but belief-in, or trust.

Now I want to be clear that there is a use of the word "belief" that is belief-in, as opposed to belief-that. Indeed, it is clear from etymological considerations that this form is the earlier - back to the PIE root *leubh- for care, trust, love.

Moyal-Sharrock, I think rightly, rejects reducing belief-that to belief-in. Rightly, since these are at least superficialy different uses, with corresponding differences in their grammar. Belief-that takes a statement as its target, while belief-in takes some logical individual.

Moyal-Sharrock goes on to commit the reverse error, attempting to reduce belief-that to belief-in. Here we might do well to recall this:
Philosophical Investigations §22:We might very well also write every statement in the form of a question followed by a "Yes"; for instance: "Is it raining? Yesl" Would this shew that every statement contained a question?

We can interchange sentences between belief-in form and belief-that form; this does not show that either has some sort of priority.

Moyal-Sharrock's discussion is broad and strongly argued, and this is but a start.

Reply to Banno I'm not a fan of spending too much time on secondary sources. I think that for the most part, they lead us astray, not always of course. Most of my time is spent reading primary source material even though Witt's OC is incomplete. He's written enough prior material to give us a good idea of his thinking. And even the ideas I've tried to expand have some connection to passages in OC. I think OC is the most lucid of all Witt's writings, so I try to take the passages in OC at face value without trying to overanalyze them. Whether I succeed at this is another story. I think when we were explaining objects in the thread on TLP there was a tendency to go beyond Witt's ideas, i.e., to overanalyze the concept. I don't want to be too dogmatic about what I'm saying here, but I think generally this is the case.

What I like reading secondary sources for is to compare my interpretation with that of others. I'm not saying there aren't good reasons to read secondary sources, only that when it comes to interpreting this or that passage in Witt's writings it's easy to go down the wrong path. Of course, it's easy to go down the wrong path no matter what you do, which is why it's a fool's errand to think this or that interpretation is correct. No matter what you say there's going to be a few people who will disagree.

I like reading Witt to see where it leads me.

Wittgenstein’s Hinge Propositions and Godel’s Incompleteness Theorem

I’ve been thinking for quite some time now that there might be a novel framework for understanding Godel’s incompleteness theorems by using Wittgenstein’s hinge propositions. Godel’s first incompleteness theorem states that in any reasonable mathematical system, there will be statements that are true but unprovable within the system. Godel’s second incompleteness theorem takes this a step further by showing that the system cannot demonstrate its consistency using only the axioms and rules of inference within that system.

I believe there is another way of looking at Godel’s conclusions that might solve the problems posed by Godel’s theorems. There seems to be a parallel between Wittgenstein’s hinge propositions and the foundational axioms of a mathematical system. Wittgensteinian hinges are outside any formal epistemological justification or doubt. If we carry this idea over into Gödel’s theorems, then the axioms of the theorems might be thought of in the same way, i.e., there’s no requirement for proof if they are the hinges that provide the framework for the system to function. In other words, the foundation is not proved from within the system but is necessary for the system to function. The foundational axioms act as hinges in the Wittgensteinian sense. This would eliminate Godel’s requirement for the axioms to be proved within the system. We could then think of the foundational axioms of mathematics, such as the Peano axioms or the axioms of set theory as hinge propositions of mathematics. They would be the basic beliefs of mathematics which would be outside any formal justification. This would eliminate the need for trying to prove the axioms within the system.

Although these two systems, viz., epistemology and formal logic, are different domains, it may be that Wittgenstein’s hinges could fulfill a role in each domain, which may provide a better way of understanding the difficulties of Godel’s theorems.
Sam26 September 03, 2024 at 21:52 #929877
Hinges provide a way of understanding Godel’s theorems without the need to justify certain basic beliefs within the system. I prefer to call these basic beliefs, non-propositional, which eliminates the need to refer to them as true or false. It seems to me that you can always ask of a true proposition, “How do you know it’s true?” – which evokes a justificatory response. Moreover, if you refer to them as true, can you also ask if they can be false? This seems to open a can of worms.

It seems to me that formal systems are held together by background beliefs, i.e., that you can’t create a formal system (epistemic or mathematical system) without the background. I’m specifically referring to the prelinguistic background that is even more fundamental than linguistic hinges. For example, the prelinguistic beliefs that occur as a result of engaging with the world, walking, running, touching, smelling, object and special awareness, etc. Even causal and simple logical relationships are probably part of these basic beliefs. So, the basic beliefs that are formed before linguistics play an important role in the more sophisticated linguistic beliefs (such as what it means to know) that come later.

Basic beliefs are important because they form the substructure that allows epistemic and mathematical systems to form without the need for justification, i.e., they are prior to our justificatory models. Basic beliefs, especially prelinguistic beliefs, are the scaffolding that allows our models of epistemology and mathematical systems to take root. These kinds of beliefs are necessarily prior to our world of justification.

I confess I don't have a background in mathematics, but I'm not sure I follow you here. As far as my understanding goes, Godel's incompleteness theorems do not show that a formal system of logic cannot prove its own axioms. That axioms cannot be proven by deductions from axioms is a foundational principle of mathematics and logic, and did not originate with Godel.

The incompleteness theorems show that formal systems of logic always produce truths that are not provable using only the axioms of the system. Even if those truths are adopted as axioms, further unprovable truths will still exist, generating an infinite list of axioms. If a given axiom ever makes that list 'complete', then the list can no longer be 'consistent', in the technical mathematical sense of those terms.

The truth-value of axioms in themselves is a question in the philosophy of mathematics (and philosophy generally). But your treatment of Wittgenstein's 'hinge-propositions' here effectively equates them with axioms – which is to say, claims that are accepted without being proven and on the basis of which formal logical reasoning depends. That is the basis of all formal reasoning, as far as I know, and not original to Wittgenstein or Godel.

Am I missing something? If Witt had meant that hinge-propositions were just like axioms, he would have said so. He had a good knowledge of mathematics, as I understand. But perhaps you are a mathematician too and you can explain where I'm going wrong here! Thanks in advance.

Sam26 September 04, 2024 at 11:19 #929944
Reply to cherryorchard I’ll try to re-word my point to make it clearer. First, a summary of Godel’s incompleteness theorems. The first theorem states that in any formal system adequate for number theory there exists true mathematical propositions (including its negation) that cannot be proven within the system. The corollary (the second theorem) is that the consistency of the formal system capable of expressing arithmetic cannot be proved using only its axioms and rules.

My point is that if we think of the propositions in Godel’s theorem (the ones that cannot be proven within the system) in the same way Wittgenstein thinks of hinge propositions (basic beliefs), viz., that hinges are outside our epistemological framework, then there is no requirement to prove the propositions within the system. We could think of Godel’s unprovable statements as hinge-like. So, Godel’s unprovable statements are necessary for the formal system to operate, just as hinges are necessary for our epistemic practices. The systems are held fast by viewing certain statements as hinges. I’m assuming you understand Wittgenstein’s point about hinges in OC.

But again, this formulation of 'unprovable statements' that are 'necessary for the formal system to operate' makes them sound more like axioms. How do they differ from axioms?

As far as I can see, there has never been a 'requirement to prove the propositions' that 'are necessary for the formal system to operate' either in Godel or elsewhere – those propositions are axiomatic and Godel did not try to prove them or to show that they could or could not be proven.

Godel showed that there would always be true but unprovable statements within any axiomatic logic system. If these statements are incorporated into the system as axioms (which are precisely those statements that are accepted as true without being proven), either those new axioms will contradict the existing ones, or they will result in the emergence of further true but unprovable statements. No system can ever fully incorporate all these true statements as axioms and remain consistent.

Again, I'm not a mathematician. But what you describe as 'hinge-propositions' sound a lot more like axioms (which form the basis of reasoning) than true but unprovable statements (which are not axiomatic).

Quoting Sam26
I’m assuming you understand Wittgenstein’s point about hinges in OC.


Thank you, but that's probably too charitable an assumption! To be honest, after reading 'On Certainty', I was surprised to find such widespread discussion of 'hinge-propositions' in the secondary literature. Wittgenstein only mentions hinges briefly and never seems to use the phrase 'hinge-propositions' at all (at least not in the Anscombe/Wright translation, unless I'm mistaken).

In section 655 he writes:

The mathematical proposition has, as it were officially, been given the stamp of incontestability. i.e.: "Dispute about other things; this is immovable – it is a hinge on which your dispute can turn."


He's talking about the proposition 12x12=144 here, which can be derived from basic axioms of arithmetic. I don't see how this relates to Godel's theorems but, again, no doubt there is much I don't understand here.

eta: I realise I've taken the above quotation out of context. But it comes from a section where Wittgenstein is teasing out certain epistemic similarities between mathematical propositions and empirical propositions. From 651:

... one cannot contrast mathematical certainty with the relative uncertainty of empirical propositions. For the mathematical proposition has been obtained by a series of actions that are in no way different from the actions of the rest of our lives, and are in the same degree liable to forgetfulness, oversight and illusion.


And 653:

If the proposition 12x12=144 is exempt from doubt, then so too must non-mathematical propositions be.


That's the context in which I understand the idea of 'incontestable', 'fossilised' or 'hinge-like' propositions in 'OC'.

The term 'hinge' occurs three times in On Certainty.

341. That is to say, the questions that we raise and our doubts depend on the fact that some
propositions are exempt from doubt, are as it were like hinges on which those turn.


343. But it isn't that the situation is like this: We just can't investigate everything, and for that reason we are forced to rest content with assumption. If I want the door to turn, the hinges must stay put.


655. The mathematical proposition has, as it were officially, been given the stamp of
incontestability. I.e.: "Dispute about other things; this is immovable - it is a hinge on which your
dispute can turn."


The third is the only example explicitly called a hinge. It is both a proposition, and true.

Wittgenstein is arguing that we conventionally equate the fact there can be no dispute concerning the meaning of a mathematical proposition with its being true. This is not how Wittgenstein treats hinge propositions. His critique of Moore’s supposedly ‘true’ statement ‘this is my hand’ revolves around Moore’s confusing an empirical truth claim with the indisputability of a hinge proposition (form of life, language game).

He is linking hinge propositions with forms of life and language games. They are all incontrovertible for the same reason. Not because they are true, but because they form a system of logic on the basis of which true and false statements are intelligible. It is not that the sum of proposition 12+12=144 is not either true or false, it is that the practices that allow us to know this are not themselves true or false. Before we can answer ether 12+12=144 is true or false, it has to be intelligible. Hinge propositions provide the bedrock of intelligibility.


657. The propositions of mathematics might be said to be fossilized. - The proposition "I am called...." is not. But it too is regarded as incontrovertible by those who, like myself, have overwhelming evidence for it. And this not out of thoughtlessness. For, the evidence's being overwhelming consists precisely in the fact that we do not need to give way before any contrary evidence. And so we have here a buttress similar to the one that makes the propositions of mathematics incontrovertible.

Wittgenstein’s “On Certainty” was a response to G. E. Moore’s essays which aimed to identify propositions that are beyond skepticism.Wittgenstein examined the idea that certain propositions serve as the bedrock or foundation for other empirical statements. He likened these foundational statements to a riverbed that must remain stable for the river to flow.For Wittgenstein, the certainty we feel about some propositions stems from their deep integration into our daily activities or “forms of life”.

Of course they are true or false. Wittgenstein isnt denying this. He is making a distinction between a micro and macro level of analysis. A particular qualitative system of interconnected logical elements ( the macro level). is implicitly used as a framework of intelligibility within which individual propositions can be true or false ( the micro level).

Wittgenstein distinguishes thoughout ‘On Certainty’ between empirical propositions and those propositions which we do not know through the test of experience, but which instead ground a way of interpreting experience. This is the distinction between the riverbed’s bedrock ( what is beyond doubt) and the shifting waters of the stream (empirical experience) that runs through it.


98. But if someone were to say "So logic too is an empirical science" he would be wrong. Yet this is right: the same proposition may get treated at one time as something to test by experience, at another as a rule of testing.

Axioms in a formal logic system are also outside all schemes of verification, because they are presupposed and form the basis on which those schemes proceed. Whether or not axioms are 'true' is, as I understand, an open question in the philosophy of mathematics. From this thread, I gather that the truth-value of 'hinge-propositions' is an open question in philosophy too.

Again, I fail to see a distinction between the 'hinge-propositions' that are being discussed here and the simple concept of axioms – claims we accept without proof in order to begin reasoning in the first place. But I also admit I do not recognise Wittgenstein as having theorised anything called a 'hinge-proposition' in 'On Certainty'. I accept that he used a door hinge as a metaphor for the way we reason, in sections 341 and 343 and again in 655. But the metaphor was not very thoroughly pursued in any of these cases, and did not strike me as particularly crucial to his line of inquiry.

Of course, the academic consensus would strongly suggest I'm wrong – that 'hinge-propositions' do indeed form a key part of Wittgenstein's argument in 'On Certainty'. I just can't seem to make that out in the text itself.

I consider the notion of hinge proposition to be redundant; it’s just another way for Wittgenstein to talk about language game and forms of life, as a hinge on the basis of which we organize so many empirical claims that it makes no sense to subject it to doubt.

It's not a good idea to consider hinges to be "outside our epistemological framework", anymore than it would be a good idea for a hydrologist not to consider the riverbed. They are rather the foundation on which an "epistemological framework" rests.

Nor is it a good idea to think of hinges as not propositional. if they are not propositional then they cannot fulfil the task set them, which is to show that other propositions are true. They cannot act as a hinge unless they are true.

It's a bit like saying that the hinges of a door must be either part of the door or part of the door frame, and so failing to recognise that they are neither and both.

Nor is it a good idea to think of Gödel's unproven sentences as "outside the system" - they are very much a part of the system.

I suspect that his use of the river analogy intentionally points back to Heraclitus. He says, for example::

97. The mythology may change back into a state of flux, the river-bed of thoughts may shift. But I distinguish between the movement of the waters on the river-bed and the shift of the bed itself;
though there is not a sharp division of the one from the other.

So what do you think it means to say that some proposition is part of our world picture? Is a world picture simply a set of facts that we believe are verifiably true? Or is a world picture a system of relations that include certain possibilities and exclude others? Is it the fact that man has been on the moon that alone constitutes the ground for its indubitably, or is it a system of grounds underlying this fact which make the fact indubitable (our awareness of the the science of space flight and our trust of media)?


108. "But is there then no objective truth? Isn't it true, or false, that someone has been on the moon?" If we are thinking within our system, then it is certain that no one has ever been on the moon. Not merely is nothing of the sort ever seriously reported to us by reasonable people, but our
whole system of physics forbids us to believe it. For this demands answers to the questions "How did he overcome the force of gravity?" "How could he live without an atmosphere?" and a thousand others which could not be answered. But suppose that instead of all these answers we met the reply:
"We don't know how one gets to the moon, but those who get there know at once that they are there; and even you can't explain everything." We should feel ourselves intellectually very distant from someone who said this.

Much had to change within the system for it to be certain that someone has been on the moon. This includes having landed on the moon and our being aware of it. It the moon missions had been kept secret we might know that the science had changed enough that it might be possible but there would still be good grounds to doubt that anyone has ever been on the moon.

Only the system of grounds provides the relative certainty that Wittgenstein is talking about throughout the book. You’re making the same error as Moore, when he looks at his hand, articulates the proposition ‘this is my hand’, and declares this to be a certainty, beyond all doubt. He believes the facts are so strong in his example
that they speak for themselves. You and Moore are confusing an empirical fact with a holistic structure, a system of convictions underlying that fact. Youre conflating a testable proposition with a rule of testing. This system is not a disconnected collection of separate facts, but a unified gestalt i. which each conviction depend on the others for its sense


98…the same proposition may get treated at one time as something to test by experience, at another as a rule of testing.

102. Might I not believe that once, without knowing it, perhaps is a state of unconsciousness, I was taken far away from the earth - that other people even know this, but do not mention it to me? But this would not fit into the rest of my convictions at all. Not that I could describe the system of these convictions. Yet my convictions do form a system, a structure.

105. All testing, all confirmation and disconfirmation of a hypothesis takes place already within a system.

It's not a good idea to consider hinges to be "outside our epistemological framework", any more than it would be a good idea for a hydrologist not to consider the riverbed. They are rather the foundation on which an "epistemological framework" rests.


I assume this is directed toward me, so I'll respond. We know that much of what Witt was saying was directed at Moore's propositions in his papers Proof of an External World and A Defense of Common Sense, so we're referring to specific propositions that Moore says he knows. Moore believes he has a justification for claiming to know "This is a hand (as he raises it to the audience)." Witt resists this notion, although he starts OC with, "If you do know [my emphasis] that here is one hand, we'll grant you all the rest (OC 1)." It seems clear to me that when Witt refers to hinge propositions or Moorean propositions he's saying that you don't know what you think you know, viz., Moore's use of the concept know doesn't apply because these statements don't fall within the domain of JTB. We don't normally justify these basic beliefs or Moorean statements. There are of course exceptions to this general rule (generally we don't justify them) and Witt points these out.

If you're reading my statements in an absolute sense, I would agree they are not always outside our epistemological framework, but Witt is saying that they generally are not within our epistemological framework (which is what I'm claiming), i.e., requiring a justification. So, I agree, that these Moorean propositions are the foundation on which our epistemological framework rests, but that doesn't mean they are part of epistemology, they support epistemology. I think OC 1 is key to interpreting the thrust of my point because Witt is saying "If you do know..." then your conclusion follows, i.e., Moore's point is epistemological, but Witt doesn't agree.

I'll just make these points for now.

Wittgenstein’s saying that there are kinds of facts which are fluid, which can change their truth value.
A language game within which such facts makes sense is not fluid. It is certain in a way that such individual empirical facts can never be. No facts with the system can cause us to become doubtful of the system itself. ‘No one has ever been to the moon’ is not a fact ‘alone’ , it is the expression of a system of belief.

Moore thinks this sureness is the result of a huge bank of empirical evidence, but Wittgenstein entertains the idea that it’s something else altogether, sometimes described in terms of context and culture, but in §359 of On Certainty described as “something animal.”

Elsewhere, however, Wittgenstein rejects the idea that Moorean propositions are in some way innate to humans as animals. Instead, he repeatedly returns to the idea that these propositions are held fast by the games and activities they are used for—that they are in some way contingently certain, but certain all the same. Wittgenstein writes:

“I have arrived at the rock bottom of my convictions. And one might almost say that these foundation-walls are carried by the whole house.”(OC §248)


I agree it is not Moore’s certainty that is at issue. It is his treatment of his certainty as an empirical fact rather than as a tacit commitment to a set of practices that hold together facts.

I think the "world in itself" didn't even concern Witt, nor did Kant really discuss much about it other than what it is not (the phenomenal). And it was the phenomenal Kant could discuss at length the various ways it is shaped by the cognitive apparatus. In fact, the "in itself' can be be almost aligned with Witt's famous "silence" on metaphysics, ethics, etc. So again, I just see this as stumbling upon what was already thoroughly discussed. He must have known he was mirroring this notion, no?

I don't mind the rehashing of old arguments, and even permuting them into language, but to not draw the parallels seems unnecessarily ahistorical.

As for outside experience, I simply mean functions for which propositional truth can even take place. Kant thought they were simply necessary, modern theories would say they’re necessary but constructed from experience. Either way, the similarity is enough to draw the parallels, I.e necessary conditions. You can try to weasel out of it by saying “outside experience” was not mentioned so it’s fundamentally different, but I see that as being overly focused on that term to make a gulf rather than splitting hairs on a vague term that functions similarly.

We don't normally justify these basic beliefs or Moorean statements. There are of course exceptions to this general rule (generally we don't justify them) and Witt points these out.


I like to provide a brief defense of Moore's Proof of an External World. I don't claim Moore would agree of my defense, but let's just say I use Moore's position as a spring board to explore what I find as limitations to Wittgenstein approach to Ordinary Language. Let's begin where Moore ends his paper with the following:

“I can know things, which I cannot prove; and among things which I certainly did know, even if (as I think) I could not prove them, were the premisses of my two proofs. I should say, therefore, that those, if any, who are dissatisfied with these proofs merely on the ground that I did not know their premisses, have no good reason for their dissatisfaction."

Throughout the paper, Moore painstaking clarifies what it means by ideas such as "internal to our minds", “external to our minds’ and ‘to be met with in space”. After showing how all these ideas make coherent sense he goes on to provide the proof of "the existence of external things.” Moore thinks he has satisfied the conditions to be a rigorous proof. One of those condition being that a premiss which was something he knows to be the case and not something which only believe to be so. The premiss he cites is "I certainly did at the moment know that which I expressed by the combination of certain gestures with saying the words ‘There is one hand and here is another’. I knew that there was one hand in the place indicated by combining a certain gesture with my first utterance of ‘here’ and that there was another in the different place indicated by combining a certain gesture with my second utterance of ‘here’. How absurd it would be to suggest that I did not know it, but only believed it, and that perhaps it was not the case!”

Moore provides an excellent example where he demonstrates how this is a reasonable example of a proof. He gives the example of someone who is tasked in finding three misprints in a particular book. This individual could be incline to doubt whether three misprints are in the book, but the one giving the task could prove that there is by simply pointing to each one, 'There's one misprint here, another here, and another here.' Interestedly, Moore concludes, "Of course, A would not have proved, by doing this, that there were at least three misprints on the page in question, unless it was certain that there was a misprint in each of the places to which he pointed. But to say that he might prove it in this way, is to say that it might be certain that there was. And if such a thing as that could ever be certain, then assuredly it was certain just now that there was one hand in one of the two places I indicated and another in the other.”

It seems Moore is suggesting that he is not absolutely certain, in some philosophical sense, that "this is one hand and here is another" but nonetheless he knows this to be the case. Does this example need to fall in the domain of "Justified True Belief" to count as knowledge? I believe Moore is showing that we ought to revise this notion of what knowledge should be, what should count as knowledge. Philosophy sometimes can play a normative role, as well as a descriptive role.

Sure, Wittgenstein can look to see how the word "knowledge" functions in our forms of life. But sometimes concepts "evolve". I am sure the notion of "knowledge" has change from the Greeks, to the Medieval period, and to our Modern period. I would think if he explored the use of "to know" during these periods that they may be somewhat different. And did he not say in "The Blue and Brown Books",

"Philosophers very often talk about investigating, analyzing, the meaning of words. But let's not forget that a word hasn't got a meaning given to it, as it were, by a power independent of us, so that there could be a kind of scientific investigation into what the word really means. A word has the meaning someone has given to it."

Well, maybe we can view Moore as trying to "evolve" the notion of knowledge. But like all things competing for our attention, may lose out to more appealing notions.

Another general comment I might make is that the presumption that some sentences are certain, presumably in virtue of their meaning, is problematic. It's not so much that a sentence is certain, as that it can be treated as certain for the purposes of a given language game. We need to look past meaning to the use to which such sentences are put.

So "Here is a hand" is not so much certain as it stands, but might be treated as certain, for some purpose.

For Witt they are not just cognitive but affective and valuative. Most importantly, for Kant innate categories make possible normative experiences but they themselves are non-normative and non-natural, whereas for Witt they are both normative and natural in that they consist of practices in the world. Witt’s practice-based concept of use unifies categories and experience via the same norm-generating processes, whereas Kant maintains a split between what is normative and non-normative, what is rational and irrational, what is categorical and what is not.

Are Wittgenstein’s notions of a language game, form of life and hinge proposition indebted to Kant’s categories? Of course, but one can say the same of the philosophies of Hegel, Schopenhauer, Heidegger Nietzsche and most other philosophers who have come since Kant. As has been said, in a certain respect we are all Kantians now. But it is one thing to show the indebtedness of modern philosophies to Kant, and quite another to claim that thinkers like Wittgenstein have reached “conclusions which Kant already implied with his ideas of "synthetic a priori truths"”.

Reply to Joshs I maintain they affectively function the same. There are things "beyond doubt". But as you said with "normative", Kant would place the necessity at the level of cognition (the container), and Wittgenstein at beliefs (the content). Kant is thinking beyond the confines of language, but necessities for which experience itself takes place. Again, why Wittgenstein seems to feel trivial. Why does saying commonsense things like, "Some things we must simply take for granted to move forward in a conversation", add anything to our knowledge?

This goes back to my claims earlier that if I say something as a politician like "Family is good", and that is taken as profound policy, something has gone wrong.

I get that Witt's later stuff is basically "Meaning comes from practice within a language community", but why cannot there be a robust debate as to whether philosophy of language come prior or after formal epistemology? Why does it have to subsume it, as many 20th century thinkers seemed to want (first with focus on formal language and logic, and then with ordinary language analysis). Meaning is use, yes yes.. But then whence meaning? Whence use?

Banno September 06, 2024 at 21:33 #930474
Reply to Richard B Thank you for that. You have taken the thread back to the context, which was sorely needed.

One way of seeing the discussion is that Moore and Wittgenstein differ as to how they would use "know". Wittgenstein would have us use "know" only in situations where there is an explicit justification that can be given, in the form of a proposition, for the belief in question. Moore is happy for us to know things that are not justified in this fashion - "here is a hand" being a case in point.

It is worth pointing out at this juncture that in English there are usually considered to be two differing sorts of knowledge, explicit and tacit, or knowing that and knowing how. Both Moore and Wittgenstein conclude that explicit knowledge as grounded in tacit knowledge, Moore leaning on the fact that he knows how to hold up his hand, Wittgenstein leaning on a somewhat convolute argument that has had some misleading consequences. So there are folk hereabouts who take hinges to be non-propositional and not truth-apt, apparently not noticing that this renders them inconsequential.

One justifies that one knows how to ride a bike by getting on the bike and riding it. One justifies that one understands "here is a hand" by waving one's hand about. They agree that the "meanings" of words are seen in what we do with them, not in an explication.

There are two major critiques here:
1) One can reasonably talk about the conditions for knowledge and experience and things prior to language, using language to describe them (Kant may represent this approach.. one done by many philosophers)
2) Witt's notion: at some point language games cannot exist without certain "hinge" beliefs. Yet we can explore where hinge beliefs originate to some degree, even using empirical methods (developmental psychology and such).

This is important because OC is not a finished work so we don't know what the editing process would have looked like, i.e., what passages would have been left in or left out. Although, certain ideas seem to have some staying power. For example, the idea that Moorean propositions are not normally justified, i.e., justification does have an endpoint. It ends with very basic beliefs. The problem is that what's basic in one context is not in another. One has to look carefully at the specific language games and contexts. In one context "Here is one hand," is outside epistemological systems, and in another, it's within the system. One needs to ask if it makes sense to doubt the proposition. That tells us a lot.

I'm mostly trying to take Witt's ideas and run with them. I'm not always agreeing with Witt or trying to stay within the confines of his thought process. I think it's fun to see where a particular line of thought goes. People who try to tell me that this or that passage says this as opposed to that are not paying attention. The thread is indeed called An Analysis of OC, but my analysis does sometimes go beyond Witt and will indeed stretch his ideas. I will at times debate this or that interpretation, but I'm not going to debate forever these differences, it distracts from the overall goal, which is to give a particular twist to OC, right or wrong. Many of my ideas coincide with what other philosophers have concluded so it's not that I'm so far out in left field that the ideas don't have some validity.

So, if I don't engage, mostly it's about not getting sidetracked or because I don't have the time to answer every question. Don't take it personally. As you've noticed I don't devote all my time to this, I post here and there.

Finally, I've devoted a lot of time to OC. I've read it more times than I can count. So, I do have fairly good background knowledge of Witt's thinking. There are only about 4 or five people in this forum who have as much or more knowledge of this text than I do.

The problem is that what's basic in one context is not in another.

I don't see this as a problem so much as a part of the answer: it's not that some propositions are always hinges, but that in order to play a language game we must set aside doubt for some propositions.

Certainty is something we do. It is not something that is found.


Sam26 September 06, 2024 at 22:08 #930479
Reply to Banno I agree. Although I make a distinction between subjective certainty and objective certainty, the latter being akin to knowledge. I think Witt made this distinction too.

1) One can reasonably talk about the conditions for knowledge and experience and things prior to language, using language to describe them (Kant may represent this approach.. one done by many philosophers)

Well, this results in pages and pages about philosophical constructs such as the thing-in-itself... silence is much preferable. But it's not the silence of the Zen master, it's the silence of doing things.

Quoting schopenhauer1
2) Witt's notion: at some point language games cannot exist without certain "hinge" beliefs. Yet we can explore where hinge beliefs originate to some degree, even using empirical methods (developmental psychology and such).

Sure. The first step here is the one given above - that not doubting is something we do, not something we uncover.

Notice that this fits exactly with the core idea that we should look to use rather than meaning.

I do want to comment on what I was saying about hinges in relation to Godel's proofs. All I was trying to say is that instead of looking at certain axioms within a particular system as something that can't be proven within the system, we could look at them as endpoints not needing proof or justification, like Witt's hinges.
Sam26 September 06, 2024 at 22:38 #930486
My thinking on OC is that Witt's biggest contribution is the idea that certain basic beliefs are the endpoints that form the bedrock of epistemological ideas. It solves the problem of the infinite regress of justifications, and it solves the problem of circularity. This is not insignificant.

The other important idea, and there are probably many more, is the way we think of doubt, viz., just as knowledge requires justification, so does doubting. People tend to think that their doubts are always warranted, but they're not. Think of knowledge and doubting as two sides of a coin. Both require a justification.
Sam26 September 06, 2024 at 23:18 #930490
In some passages, Witt seems to compare Moore's statement about knowing this is a hand to someone's conviction of a particular belief. In other words, when Moore states what he knows, at least in these passages, it seems to be more a function of his convictions than a function of knowledge. For e.g., in OC 6 he says, "And through this misuse [misuse of the word know] a queer and extremely important mental state is revealed." I don't think it's a stretch to think that this mental state is the mental state of conviction. For instance, "Suppose I replace Moore's 'I know' by 'I am of the unshakeable conviction' (OC 86)." Or look at OC 91, "But has he got the right ground for his conviction? For if not, then after all he doesn't know (Russell)." Witt seems to be pointing out the subjective nature of what Moore is saying. Of course, as I've already pointed out, Witt uses certainty in two different senses, subjective certainty and objective certainty, the latter is akin to knowing, the former not, at least not in this context. Knowledge is not generated by some inner subjective point of view, at least not the knowledge that Moore's trying to convey to the skeptic.
Banno September 06, 2024 at 23:25 #930491
Reply to Sam26 Care might be needed to avoid a foundationalist reading of OC. I don't think there are some sentences that are unquestionable in an absolute sense. It's rather that if we are going to perform some given task, we must take some things for granted - if you would do maths, you need to grant that 1+1=2; if you would pick your nose, you must take this to be a hand; and so on.

Reply to Banno Well, as you know I do read a kind of foundationalism into OC, but it's nothing like traditional foundationalism.

Sam26 September 07, 2024 at 00:00 #930502
Reply to Banno So, the analogy I use over and over again is to think of foundational in the same way that the rules of chess, the board, and the pieces are foundational. One doesn't need to justify these components they are just there as part of the background needed to play the game. The games rest on these components, i.e., they're foundational to the game. You can also think of language games in the same way, viz., resting on certain implicit and explicit rules within our forms of life.

It's interesting to note that different language games reflect different endpoints. However, it seems to me that some endpoints are not really hinges, and the way we can see this is by asking if it makes sense to doubt one's endpoint. For e.g., I've listened to some philosophers who want to place belief in God in the same category as Witt's hinges, so within their language game, it's a given, in the same way, this is a hand is a given. However, there is an important test to see if your hinge is proper, viz., does it make sense to doubt that proposition? Compare this is a hand and belief in God, it's much more natural to doubt the latter. There is an exception, let's say you had a veridical encounter with God, then in that case it could be considered a hinge. However, trying to prove your experience would be very difficult indeed.

One justifies that one knows how to ride a bike by getting on the bike and riding it. One justifies that one understands "here is a hand" by waving one's hand about. They agree that the "meanings" of words are seen in what we do with them, not in an explication.


These situations show that one is performing a practice in a particular way, and one’s understanding is this particular way of ‘knowing how’. These performances dont preclude the possibility that they might be performed in an entirely different way by some other culture, to produce entirely different meanings. If the game ‘chess’ is performed according to an entirely different set of rules in that other culture, then my playing chess according to my rules will not justify to that culture my claim that I know how to play chess. It will justify that I indeed know how to do something, but not what they understand as chess. What we do with words forms a system, and how that system of practices is organized as a language game determines its meaning.

If you and I inherit the same system of practices, then within that same system I may be able to justify that I know how to do something simply by doing it, which is what Wittgenstein means by certainty, that the performance simply IS the justification. Within this shared system of practices called riding a bike, I may make a mistake, and this possibility of error within the shared system is what Wittgenstein calls knowing. Justification, verification, being able to be wrong all are possible within a shared system, but are not applicable when we compare two different language games. If you and I are making use of different language games, then performances like riding a bike , playing chess or waving my hand which appear justified to me will not to you. They will appear unintelligible, even if you call my performance ‘incorrect’.

When I say the word ‘bike’ you already have a system of practices in mind, involving use of pedals, steering, balance, etc. Of course, your idea of bike doesn’t have to include all of those. Your bike may be electric and not have pedals, it may have three wheels and not require balance. But your practical understanding of bike will probably be general enough that you can participate with no problem in a language game in which criteria of successful bike-riding can be agreed on. But what if you live in a place where the language game ‘bike’ involved an entirely different system of relations, where bikes were flying, floating or digging devices? For you, someone justifying they know how to ride a bike by pedaling something with wheels on a street would be unintelligible as bike-riding.

Wittgenstein would have us use "know" only in situations where there is an explicit justification that can be given, in the form of a proposition, for the belief in question.


Let's look at a few examples:

3. If e.g. someone says "I don't know if there's a hand here" he might be told "Look closer". - This possibility of satisfying oneself is part of the language-game. Is one of its essential features.


What is the propositional justification? As I read it, he intends the opposite. Looking and seeing does not require propositional justification. But, of course, as he knows, "look closer" does not satisfy the skeptic who questions the existence of what is seen.

7. My life shows that I know or am certain that there is a chair over there, or a door, and so on. - I tell a friend e.g. "Take that chair over there", "Shut the door", etc. etc.


Sit. Open the door. It is in such cases a matter of acting and doing not of saying. We know how to sit or open doors, but knowing that there is a chair or door in not a matter of knowing how. Justification does not even enter the picture.

90. "I know" has a primitive meaning similar to and related to "I see" ("wissen", "videre"). And "I
knew he was in the room, but he wasn't in the room" is like "I saw him in the room, but he wasn't
there". "I know" is supposed to express a relation, not between me and the sense of a proposition
(like "I believe") but between me and a fact.


This is related to 3: "look closer".

The passage continues:

So that the fact is taken into my consciousness. (Here is the reason why one wants to say that nothing that goes on in the outer world is really known, but only what happens in the domain of what are called sense-data.) This would give us a picture of knowing as the perception of an outer event through visual rays which project it as it is into the eye and the consciousness. Only then the question at once arises whether one can be certain of this projection. And this picture does indeed show how our imagination presents knowledge, but not what lies at the bottom of this presentation.


This is the source of modern skepticism. What Descartes calls the problem of judgment.

20. "Doubting the existence of the external world" does not mean for example doubting the
existence of a planet, which later observations proved to exist.


This is what Moore misses. If one doubts the existence of the external world then one would doubt the existence of something in that world - a planet or a hand. A theory of perception inserts itself" between me and a fact", leading to doubt and the demand for justification

Supose the rules they follow are phrased in terms of - I don't know, it's your argument - river gods against mountain gods or some such. If what they do is equivalent to a game of chess, then their rules are functionally equivalent to the rules of chess - a translation.

And if they differ so substantively that the actions performed are not equivalent to a game of chess, then you have no grounds to claim they are playing chess...

Same with your answer to Reply to wonderer1; if their "bike" is used to dig holes, then the equivalence of the name "bike" is incidental; your claim that the digger is a bike is groundless.

You’re making Wittgenstein’s point for him. He sees Moore’s raising of his hand as a performance which is grounded in a picture of the world which cannot be proved more correct than any other. To doubt the truth of this picture is to substitute a different picture, a different language game, just as doubting the picture of the world implied by the rules of chess is to no longer be playing chess. Moore’s demonstration convinces doubters of its certainty by bringing them to look at the world in a different way, not by satisfying them of its correctness.

I agree with @Sam26. For Wittgenstein the distinction between certainty and knowledge is that between a conviction or picture of the world, and a justifiable proposition. My picture of the world may have telling grounds, but not grounds on the basis of which I can prove that picture to be more correct than any other.


92…if Moore and this king were to meet and discuss, could Moore really prove his belief to be the right one? I do not say that Moore could not convert the king to his view, but it would be a conversion of a special kind; the king would be brought to look at the world in a different way.

This not to contest what you said. My preference when interpreting a text is not to bring other texts into it. It adds another layer of questions. I don't know how Moore might have responded, or what Wittgenstein thought of Hume's contention if he was aware of it. It just makes it cleaner.

From a chapter on Hume and Wittgenstein in "Impressions of Empiricism" Oswald Hanfling says:

Wittgenstein gave an interesting reason for his non-reading of Hume. He said that he could not sit down and read Hume, because he knew far too much about the subject of Hume’s writings to find this anything but a torture. In a recent commentary, Peter Hacker has taken this to show that ‘Wittgenstein seems to have despised Hume’. Hume, he adds, ‘made almost every epistemological and metaphysical mistake Wittgenstein could think of’.

Wittgenstein points out the ineffectiveness of self-justification, buts agrees that it is certain that "This is a hand". So he is loath to say say he knows "this is a hand", while agreeing that it is indubitable. His solution is along the lines of treating it as fundamental to the way we use word in our interactions, as a foundation to the word games. He does not come to a conclusion, although conclusions have been read in to the text by others.

For my part, something like Searle's account of language must be correct, were there are certain things that must be taken as granted in order for a language game to take place – there must be some agreement amongst the "players" as to what is occurring. On that account we might read "This is a hand" as something like "This counts as a hand for the purposes of our everyday encounters", where the ..."counts as..." sets up the institution of calling this waving, nose-picking, pen pushing thing a hand.

Problems will occur when hinges are said to be non-propositional, or not true, as Moyal-Sharrok wishes to. This needs a fair amount of tidying up, but it is clear that if some belief is going to function as part of an explanation for a behaviour, it needsmust be truth-functional.

Perhaps the difference I have with her is that I do take beliefs to be evaluative attitudes. Being so is how they relate to actions, and without acts, beliefs are nothing.

I know that a sick man is lying here? Nonsense!

This has nothing to do with proposition justification of a knowledge claim because Wittgenstein denies that it is a proper use of the term 'know'.


This is an example that fits my case exactly. Wittgenstein is pointing out that there is no justifying proposition that supports "I know that a sick man is lying here", that it is instead something seen in what is before us. Hence, he says that it is nonsense to say "I know...".

You seem to think that it counts against what I have said, when it is entirely supporting what I said. So: Quoting Fooloso4
The belief in question is that there is a sick man lying there. What is the proposition that justifies that belief? Or, more to the point, where is the need for justification?

Yes, that's right - there is no justifying proposition, and hence saying "I know..." is for Wittgenstein illegitimate.

You seem to want to disprove my case by presenting things which support it.

We're never going to come to a consensus on OC, that's clear. There will always be some interpretation that someone has that you'll disagree with. What's important is that Witt established that there are some very basic beliefs about the world (call them hinges, foundations, Moorean propositions, call them what you like) that are starting points for language games, a place where there is no need for justification.

I think this idea has ramifications beyond epistemology. I think it solves the problem posed by Godel's two theorems. These hinge beliefs seem to exist in any system where proofs are required, whether epistemological or mathematical. This of course goes beyond anything Witt talked about in OC, but I think it has merit.

Quoting Joshs
You’re making Wittgenstein’s point for him. He sees Moore’s raising of his hand as a performance which is grounded in a picture of the world which cannot be proved more correct than any other. To doubt the truth of this picture is to substitute a different picture, a different language game, just as doubting the picture of the world implied by the rules of chess is to no longer be playing chess. Moore’s demonstration convinces doubters of its certainty by bringing them to look at the world in a different way, not by satisfying them of its correctness.


Quoting frank
If Moore knows, that would mean there's a sense of "know" that amounts to being unable to doubt. And per Hume, you can't prove what you can't doubt. So Moore would have some kind of unprovable knowledge, which doesn't sound right.



Moore's paper, "Proof of an External World”, is an appeal to common sense. His intuition tells him that a philosophical analysis arriving at a radically skeptical answer is not a source of truth but evidence that something has gone wrong. I believe Wittgenstein would hold the same position as Moore when he says, “I certainly did at the moment know that which I expressed by the combination of certain gestures with saying the words ‘There is one hand and here is another’. I knew that there was one hand in the place indicated by combining a certain gesture with my first utterance of ‘here’ and that there was another in the different place indicated by combining a certain gesture with my second utterance of ‘here’. How absurd it would be to suggest that I did not know it, but only believed it, and that perhaps it was not the case!” However, Wittgenstein seems to think Moore is in error here in a different way. I believe Norman Malcolm summaries this position nicely when he says:

"But, this insight led Moore into an error. (This is the second layer of meaning.). His perception of the absurdity of saying , in that situation, "I don't know if I have clothes on (or have hands)" drew him into the assumption that it would be correct to say "I know I have clothes on." Yet what Moore had actually perceived was that nothing in that situation made a doubt as to whether he had cloths on intelligible. He should have concluded that both "I don't know" and "I know" were out of place in that context. "I know" is often used to express the absence of doubt. But the absence of doubt and the unintelligibility of doubt are very different things. Wittgenstein says in the Investigations, "I know...may mean "I do not doubt...but does not mean that the words "I doubt...are senseless, that doubt is logically excluded." Wittgenstein is referring here to the way that "I know..." is used in ordinary language. He is saying, correctly, that this expression is not used in ordinary language to make a conceptual, philosophical point. But this is kind of point that Moore needed to make, namely, the point that the statement "It is uncertain that I have clothes on" would be a conceptual absurdity in that situation. I suspect that Moore was misled here by the assumption of Excluded Middle: "Either I know it or I don't know it." He perceived that "I don't know it" couldn't be said, and wrongly concluded that "I know it" must therefore by right and true." (Moore and Wittgenstein on the Sense of "I know")

Some remarks on this summary

I find it strange to not say "I know here is one hand" in the particular context. Would it also be absurd for Moore to say in front of such an audience of skeptical philosophers that "I know it is raining outside" while looking outside the window while it is raining. Malcom says, "Being perfectly certain (i.e. objectively certain) of something in the sense of regarding it as unintelligible that one might be wrong-is an attitude, a stance, that we take towards various matters: but this attitude does not necessarily carry truth in its wake. (Nothing is Hidden)". But in these contexts, are they not carrying "truth in its wake." How is what Moore is doing, by holding up a hand and pointing to it and saying "Here is one hand" making a conceptual point only? Is this not a way of establishing the truth, or the correctness of what he is saying? Moore is not trying to describe the language game "I know", he trying to get the language game of "I know" right. He is responding to the skeptical philosopher that has taken the language game of "I know" and distorting it in such a way that knowledge becomes a logical impossibility. For Moore, in the example he provides, "knowing that" merges with "knowing how". Moore is aware of the truth, understands the fact that he has two hands by demonstrating that he can point to one hand and saying "Here is a hand." Why can't there be other ways of clearing up philosophical confusion other than describing how words are ordinarily use. For example, why not tidy up the concept itself, narrow its scope, broaden its scope, eliminate its absurdities, etc.

I think the rudder of OC is that people could walk away from Moore's work thinking that because he used the word know, that his assertion is justifiable when it's not. In other words, he's heading off more mistaken metaphysics?
Count Timothy von Icarus September 09, 2024 at 13:01 #930954
I suppose a key difference I see is that Moore is ultimately concerned with the truth. It's not just that he knows he has a body, but also that it's true—it really is the case that he has a body. What bothers him isn't just the doubt of the obvious.

Whereas, I at least try to read "On Certainty," as being about, well... certainty—justification, etc. After all, Wittgenstein didn't title it "On Truth." At least, I think this is a more charitable reading. Certainly, there are folks like Rorty who think Wittgenstein is telling us about truth. Indeed, Rorty argues that the main benefit of Wittgenstein’s philosophy is that it has shown us that questions about “which pieces of our language lock on to reality and which do not,” and the questions of metaphysics and truth more generally, are “simply... a waste of time.”

Likewise there are post-structuralist readers of Wittgenstein who claim that his findings suggest cognitive relativism, discussed in the other Wittgenstein thread on nested forms of life.

Either of these views deflate truth. Yet in doing so they seem to recreate the same sort of skepticism that Wittgenstein is at pains to try to correct.

I'd argue that it is possible for us to accept that our notions of truth are inextricably bound up in malleable social practices and language games without jettisoning the idea that there is something external to human social practices grounding such notions, that our language games are not arbitrary, nor are they determined by "nothing but" social practices (i.e., the principles of social practice are not self-contained and subsistent, nor arbitrary and untinelligible). So, we can agree that claims as basic as "I have hands," require the use of some language game, that they always take place in the context of such a game, without having to conclude that our having hands or not is merely a matter of language games. All such systems have first principles, but this only implies a sort of deflation if one assumes first principles are arbitrary.

Ultimately, it seems to me that Wittgenstein is circling around the same ideas Aristotle grapples with in his writings on discourse and the instruments of reason. A crucial question here then, which I do think Wittgenstein leaves vague, is if reason is "nothing but" these tools and instruments.

Obviously for Aristotle the two are not equivalent. Logic isn't just about speech. Logic isn't just formal logic. By Wittgenstein's time logic has largely been reduced to mere form. Yet material logic is important too; there is form and matter. So he will tell us things like this in the Prior Analytics:

"All syllogism, and a fortiori demonstration, is addressed not to the spoken word, but to the discourse within the soul, and though we can always raise objections to the spoken word, to the inward discourse we cannot always object."

Basically, we can speak the untinelligible. We can say "square circle," or "A is B and ~B," but this is not equivalent with believing the untinelligible.

In a way, "On Certainty" is an excellent demonstration of the foibles of reducing logic, and discourse as a whole, to form (although it is perhaps not intended that way).

It is assuming there is something ‘external’ to human social practices which leads to dualism, skepticism and arbitrariness. Our practices are not on one side and the world on the other of a divide . Our linguistic practices are grounded in and express material circumstances as those circumstances interact with our practices. As Joseph Rouse argues:


“The "objects" to which our performances must be held accountable are not something outside discursive practice itself. Discursive practice cannot be understood as an intralinguistic structure or activity that then somehow "reaches out" to incorporate or accord to objects. The relevant "objects" are the ends at issue and at stake within the practice itself. The practice itself, however, already incorporates the material circumstances in and through which it is enacted

Reply to Joshs

I don't disagree with the quote. However, I do disagree with your formulation that the world is "nothing but social practice," and "social practices all the way down." There is an important sense in which a rock or a horse is not a social practice. But you seem to be stretching the term "social practice," to the point where it has at best a merely analogical relationship to how the term is usually used, since it's straightforwardly ridiculous to claim a horse is a "social practice," given common usage of the term, so I may be missing something.

Is the idea at work here also a sort of panpsychism?

Anyhow, a rejection of subject/object dualism, a rejection of truth as mere correspondence, and embrace of enactivism and phenomenology (hallmarks of most pre-modern philosophy anyhow) need not require the assertion that a horse and its intelligibility have no principles/causation outside human social practice.

Here it is worth considering Kenneth Gallagher's summation of the metaphysical (as opposed to physical) principle of causation—“that the order of becoming and existence must be intelligible; that no phase of the process of contingent existence is intelligible in itself; and that therefore contingent existence is always relative existence, essentially referred, qua existing to another.” To be intelligible—to not be arbitrary—social practice must have its explanation in something other than itself since its essence does not explain its existence. On the view that the world is intelligible, such an explanation must be possible.

For example, human cultures have come up with different ways to categorize the colors. However, no cultures gave names to colors corresponding to light of ultraviolet wavelengths. Why? Because human beings, and our hominid ancestors, do not have photoreceptors capable of distinguishing UV light (unlike most insects). But the biology of the human eye, its lack of sensitivity to UV light, can only be considered a "social practice," if we use the term equivocally. Eyes are something humans have by nature, not an activity they engage in (except to the extent that all form is activity).

It’s not social practice all the way down, it’s normativity all the way down. That is, the contingent relationality of existence doesn’t ground itself in some non-normative explanation. Rouse doesn’t separate nature and culture. He instead refers to ‘nature-culture’ as a single entity. This doesn’t mean that linguistic practices directly influence the nature of DNA functioning in rats. It means that the physiological and environmental culture within which genes operate influence how they operate, and the environment within subatomic processes occur shape the nature of those processes and even their ‘lawfulness’.

The biology of the human eye is not a social practice, but it is a practice. The eye exists by functioning, and its functioning takes place within an integrated internal and external milieu which continually shape how it functions, in a way not unlike the way that linguistic practices shape the meaning of concepts for humans. We know now that environmental factors directly shape genetic structures, so any attempt to locate a pre-cultural explanation for the origin of an eye will be lacking.

115. We are interested in the concept and its place among the concepts of experience.
— Philosophy of Psychology - a Fragment



111. Two uses of the word “see”.
The one: “What do you see there?” - “I see this” (and then a description, a drawing, a copy). The other: “I see a likeness in these two faces” - let the man to whom I tell this be seeing the faces as clearly as I do myself.
What is important is the categorial difference between the two ‘objects’ of sight.

He goes on to say at 116:

But we can also see the illustration now as one thing, now as another. - So we interpret it, and see it as we interpret it.

The idea of seeing something according to an interpretation blurs the line between seeing and thinking. "Now I see it" can mean, "Now I understand". Seeing is not limited to passive reception, it involves both perception and conception.

254. The concept of an aspect is related to the concept of imagination.
In other words, the concept ‘Now I see it as . . .’ is related to ‘Now I am imagining that’.
Doesn’t it take imagination to hear something as a variation on a particular theme? And yet one does perceive something in so hearing it.

The focus on propositions can occlude the importance of seeing for both the early and latter Wittgenstein. Seeing connections involves making connections and seeing things in light of this perspective.

Working in philosophy -- like work in architecture in many respects -- is really more a working on oneself. On one's interpretation. On one's way of seeing things. (And what one expects of them.) (Culture and Value)

What a Copernicus or a Darwin really achieved was not the discovery of a true theory, but of a fertile new point of view. (CV 18)

How is what Moore is doing, by holding up a hand and pointing to it and saying "Here is one hand" making a conceptual point only? Is this not a way of establishing the truth, or the correctness of what he is saying? Moore is not trying to describe the language game "I know", he trying to get the language game of "I know" right


One doesn’t get a language game right or wrong, one gets issues defined within the parameters of a language game correct or incorrect . The game itself, the particular pattern of connections between elements that sets up the rules and criteria of validation, is grasped like a picture.

Not all beliefs have justification. If a belief is to count as a piece of knowledge, then according to the usual account, it must be justified. Hence unjustified true beliefs on that account do not count as knowledge.

If A justifies B, presumably the truth of A justifies B. I don't know what could count as a justification that could not be put into propositional form and take a truth value.

There's a bunch of misunderstanding about "propositional form". What should be understood is that if A justifies B, then B is true because A is true. Hence it should be possible to provide a proposition that states A.

We have to be careful to recognize distinctions in the sense of ‘existence’. For instance, if we ask ‘does this chair exist?’, we might mean , does it persist as relatively self -identical over time for me when I observe it. Or we might mean, does it exist objectively such that its existence does not depend on an observer. The kind of certainty of existence that Wittgenstein has in mind with respect to the chair is the certainty of the intelligibility of the scheme of understanding underlying any and all senses of the word ‘existence’. Put differently, it doesnt matter what we mean by the ‘existence of the chair’ for Wittgenstein. There can be 10 people in a room and all have a different sense of what the existence of the chair means. But all can be equally certain of their pronouncement that this is a chair, despite the fact that there is no correct proposition here to arrive at.
Built into the pronouncement is a set of rules or criteria for correctness , and it is these rules and criteria that are certain in a relative sense , for a period of time, not any particular fact concerning chairs that are framed by the criteria.

Is that a rabbit or a duck I see in that drawing? If I say I’m certain of the existence of a rabbit there, in Wittgenstein’s sense certainty here means only that I’m certain that I interpret the pattern of lines in that particular way rather than another way.

There are two ways to know - explicit and implicit, knowing that and knowing how. In PI Witti deals in knowing that – with propositional knowledge. But arguably Moore was dealing with knowing how – setting out how we use words like "here" and "hand" and "is".

And I don't think this is at odds with what Wittgenstein has to say.

So "I know this is a hand" might be more like "I know how to ride a bike" than "I know the distance to the shops".

The justification for "I know how to ride a bike" is getting on the bike and riding it.

But this is not about phenomenology, not just about perceptions. It is about the interactions between you, the chair and the folk around you.


Perception is fundamentally about interactions between us and the world, seeing as a form of doing, as phenomenologists such as Husserl and Merleau-Ponty showed. And Wittgenstein’s copious analyses of perceptual phenomena in PI reveal an intricate link between his notion of ‘seeing as’ with respect to perceptual phenomena like the duck-rabbit and certainty pertaining to material objects.


The concept of 'seeing' makes a tangled impression. Well, it is tangled.—I look at the landscape, my gaze ranges over it, I see all sorts of distinct and indistinct movement; this impresses itself sharply on me, that is quite hazy. After all, how completely ragged what we see can appear 1 And now look at all that can be meant by "description of what is seen".—But this just is what is called descrip­tion of what is seen. There is not one genuine proper case of such description—the rest being just vague, something which awaits clarification, or which must just be swept aside as rubbish.
Here we are in enormous danger of wanting to make fine distinc­tions.—It is the same when one tries to define the concept of a material object in terms of 'what is really seen'.—What we have rather to do is to accept the everyday language-game, and to note false accounts of the matter as false. The primitive language-game which children are taught needs no justification; attempts at justification need to be rejected.

Take as an example the aspects of a triangle. This triangle
can be seen as a triangular hole, as a solid, as a geometrical drawing; as standing on its base, as hanging from its apex; as a mountain, as a wedge, as an arrow or pointer, as an overturned object which is meant to stand on the shorter side of the right angle, as a half parallel­ogram, and as various other things.

"You can think now of this now of this as you look at it, can regard it now as this now as this, and then you will see it now this way, now /j-." — What way? There is no further qualification. But how is it possible to see an object according to an interpretation? — The question represents it as a queer fact; as if something were being forced into a form it did not really fit. But no squeezing, no forcing took place here. (PI p.200)

Wittgenstein juxtaposes these two statements, showing that knowledge must admit to the possibility of doubt.

So "I left the keys in the room and no one has been in there" is a justification, for "I know the keys are on the table" - there is room for doubt. But "The keys are on the table" is no justification for "I know the keys are on the table". Yet if the keys are on the table, then we can be certain that "The keys are on the table" is true.

Quoting Fooloso4
Why isn't showing the key on the table sufficient to conclude that I knew where the key is?

Good question, despite the mixed tense.
13. For it is not as though the proposition "It is so" could be inferred from someone else's utterance: "I know it is so". Nor from the utterance together with its not being a lie. - But can't I infer "It is so" from my own utterance "I know etc."? Yes; and also "There is a hand there" follows from the proposition "He knows that there's a hand there". But from his utterance "I know..." it does not follow that he does know it.

Supose that you had guessed that the key was on the table. Then "the key is on the table" is not sufficient evidence to conclude that you knew where the key is. A guess will not suffice - it is not a justification for your claim to know.

But moreover, this is the sort of puzzle that Wittgenstein is trying to unknot.

I do want to comment on what I was saying about hinges in relation to Godel's proofs. All I was trying to say is that instead of looking at certain axioms within a particular system as something that can't be proven within the system, we could look at them as endpoints not needing proof or justification, like Witt's hinges.


But we don't choose to 'look at axioms' as 'something that can't be proven within a system' – that is what axioms are (it is simply what the word 'axiom' means). The unprovable statements – or 'Godel sentences' – theorised in Godel's incompleteness theorems are not axioms.

Axioms are indeed something like Wittgenstein's 'hinges', in that we accept them without proof and they form the basis of a system of reasoning. But that has nothing to do with Godel or his theorems.

It also seems on the face of it very strange to describe 'hinges' as 'endpoints'. The whole idea of a 'hinge' is that it stays in place so something else can productively move or turn. If Wittgenstein had meant to conjure up the idea of an endpoint, he could surely have chosen a better metaphor than 'hinge'.

Quoting Sam26
I think this idea has ramifications beyond epistemology. I think it solves the problem posed by Godel's two theorems. These hinge beliefs seem to exist in any system where proofs are required, whether epistemological or mathematical. This of course goes beyond anything Witt talked about in OC, but I think it has merit.


I'm not sure what 'problem' you suggest is being solved here. What is the 'problem' posed by Godel's theorems? As I understand, the theorems are in fact quite useful and have practical applications in fields like computer science. No doubt, Godel's work poses problems for earlier mathematical projects like Hilbert's programme. But in contemporary mathematics, as far as I understand (not being a mathematician myself), Godel's work is not really a 'problem' to be 'solved'.

Further, the semantic counterpart to the unprovable statements in Godel's incompleteness theorems would not be anything like a 'hinge belief'. It would be something more like the liar's paradox – a self-referential statement that cannot be both true and provable at once. Godel himself used the example of the liar's paradox in the introductory section of his paper advancing the incompleteness theorems. Wittgenstein responded to that example directly in his 'Remarks on the Foundations of Mathematics'.

As my understanding goes, contemporary mathematicians generally do not consider Wittgenstein's reading of Godel useful. I am not a mathematician and cannot claim to understand the mathematical implications of Godel's work or the validity of Wittgenstein's response. But I am cautious of philosophical theories that claim to 'solve', refute, or have other decisive implications for complex theories in fields like physics or mathematics.
Sam26 September 13, 2024 at 08:05 #931659
My interpretation of Wittgenstein and hinge propositions is that hinges are neither true nor false, i.e., hinges have a role similar to the rules of a game. I’m specifically referring to the use of true and false as something verified by facts, i.e., something justified within an epistemological system. “If the true is what is grounded, then the ground is not true, nor yet false. If someone asked us ‘but is that true?’ we might say ‘yes’ to him; and if he demanded grounds we might say ‘I can’t give you any grounds, but if you learn more you too will think the same (OC 205, 206).” One can use “true,” but note it’s not an epistemic use of the concept as justified true belief. Rational discourse requires that there be these basic beliefs for rational discourse to function.

If someone asked, someone who is just learning chess, “Is it true that bishops move diagonally?” I would answer “Yes.” And if they further asked, “How do you know (an epistemological question)?” I might respond “It’s just one of the rules of the game.” In this case, the use of true is not justified, it’s just accepted as a basic belief without any grounding.

“But it isn’t that the situation is like this: We just can’t investigate everything, and for that reason we are forced to rest content with assumption. If I want the door to turn, the hinges must stay put (OC 343).”

Not only do hinges make it possible for rational discourse, but they also set the limits of what can be reasonably doubted.

The biology of the human eye is not a social practice, but it is a practice. The eye exists by functioning, and its functioning takes place within an integrated internal and external milieu which continually shape how it functions, in a way not unlike the way that linguistic practices shape the meaning of concepts for humans. We know now that environmental factors directly shape genetic structures, so any attempt to locate a pre-cultural explanation for the origin of an eye will be lacking.


I don't have any problem with the general description, because it seems to pretty much the insight that "act follows on being," that the eye has a function as part of a being, etc. However, exchanging "act" for "social practice" seems to introduce an equivocal usage of "practice" and "social," or "normative."

The "not unlike" highlighted above is important because, if how rocks interact with flowing water in riverbeds is "normativity all the way down," it is so in a way that apparently uses the term "normativity" in a way disconnected from what it normally means (or at the very least the likeness is not at all apparent). The likeness between say "river bed evolution and language evolution" seems at best analogical, but I am not even sure what the analogy is supposed to be because these things only seem "not unlike" each other in the very general sense that all things might be said to have something in common.



Same with the usage of "culture" wed to "environment" below. TBH, it seems like trying to say two different things at once. In what sense is a physical enviornment a "culture." The claim that environments effect genes or subatomic processes seems pretty uncontroversial, but what is "culture" even supposed to add here?

This doesn’t mean that linguistic practices directly influence the nature of DNA functioning in rats. It means that the physiological and environmental culture within which genes operate influence how they operate, and the environment within subatomic processes occur shape the nature of those processes and even their ‘lawfulness’.

I would add that environment-organism isn't a master-slave relationship. Living things have been altering their environments since life started. A successful biosphere bends its surroundings to its needs. What humans have done to the land surface of the planet is a drastic case of something that's pretty typical for living things.

Yes, that's a good point. This is why dispensing with final causality in biology is so difficult. But final causality also goes off the rails when we decide that what constitutes "a being" is arbitrary. Then we end up with attempts to explain the telos of rocks, which have no organic unity and are more bundles of external causes (obviously, they do act in the way all mobile being acts, but not in the way animals do).

I think some of the more successful attempts to explain culture have followed on the doctrine of signs/semiotics, and the distinction between the umwelt and the human species-specific lebenswelt.

True. Final cause is built into the meaning of life. I think people who want to look at the whole scene more holistically are experimenting philosophically. As you say, at the borders it starts to become confusing.

Culture is fascinating to me. I came across a book by a structuralist once (can't remember the name now). But he was talking about German religion specialists who discovered that Native Americans have symbolism that echoes what we call gnosticism. So they concluded that the origin of these images must be back more than 10,000 years. The structuralist point was that if you're going to push it that far back, just admit that you don't know where it's coming from, and that it could be arising independently due to structure.

To Josh's point, the eye has evolved independently around 50 times. Maybe a thing that life keeps doing in response to light is somehow structural? By the way, are you German?

My interpretation of Wittgenstein and hinge propositions is that hinges are neither true nor false, i.e., hinges have a role similar to the rules of a game.


Within the game, according to the rules, it is true that some things are allowed and others not.

One can use “true,” but note it’s not an epistemic use of the concept as justified true belief.

To say that hinges are justified in any epistemic sense is to miss the main thrust of OC. It would be to "...grant you [Moore] all the rest (OC 1)." Hinge propositions are not subject to verification or falsification (the doubt) within the system, they allow all our talk of epistemic justification and doubting to take root. In other words, they are the ungrounded linguistic framework that allows the door to swing (the door of epistemology). This is why justification ends with basic beliefs, and why it solves the infinite regress problem. They form the bedrock of how epistemic language gets off the ground in the first place.

There is not a single agreed upon sense or meaning or assumptions that define the term 'epistemic', but I do not think we can deny that epistemology deals with the problem of knowledge. Clearly from beginning to end Wittgenstein was concerned with the problem of knowledge. It is one thing to claim that his epistemology in OC differs from more traditional views, but quite another to deny that it is epistemology. Annalisa Coliva and Danièle Moyal-Sharrock have edited a book titled "Hinge Epistemology"


Quoting Sam26
Hinge propositions are not subject to verification or falsification (the doubt) within the system


In OC Wittgenstein identifies one hinge proposition: 12x12=144. This propositions is true. 12x12 = any other number is false. If one doubts it, it can quickly and easily be demonstrated. If this cannot be proven then there can be no mathematical proofs.

To say that 12x12 =144 is a hinge proposition is to think of it as a rule for arriving at the product 144. The result of a calculation can be true or false but the rule for arriving at the result is neither true nor false. The rule merely stipulates the criterion for determining what would constitute the correct or incorrect answer.

Wittgenstein calls it a proposition not a rule. We follow rules. We do not follow propositions. Propositions are either true or false. Calling it a hinge does not change that.

That is to say, the questions that we raise and our doubts depend on the fact that some
propositions are exempt from doubt, are as it were like hinges on which those turn.

(OC 341)

That is to say, it belongs to the logic of our scientific investigations that certain things are in
deed not doubted.

If I want the door to turn, the hinges must stay put.

It is not, as some would have it, that a hinge is neither true nor false, it is that its truth is not doubted.

What is the rule for arriving at the answer? When we calculate correctly we arrive at the correct answer. Are there infinite rules for the infinite amount of numbers that can be multiplied? Does anyone know or follow these rules or do they calculate?

Key Themes of Thread:

1. Context and Purpose
• On Certainty is Wittgenstein’s response to G.E. Moore's papers Proof of an External World and A Defense of Common Sense.
• Wittgenstein challenges Moorean propositions (e.g. “Here is one hand”)
• As part of Wittgenstein’s critique he addresses skepticism and the nature of doubt

2. Hinge Propositions:
• Hinges are foundational beliefs that form the bedrock of our language games and knowledge claims
• They aren’t subject to traditional epistemological categories of justification and truth
• Examples include basic beliefs about having hands, the existence of objects, and other minds
• They are part of our inherited background or world picture
• There are a variety of different hinges, with some being more immutable than others


3. Knowledge and Certainty
• OC distinguishes between knowledge and subjective certainty (conviction)
• Moore’s claims are more akin to expressions of his convictions rather than knowledge claims
• Knowledge (JTB) requires truth, justification and the possibility of doubt
• Knowledge claims must be demonstrated rather than stated


4. Doubts Role
• Doubting is not always meaningful; some are logically excluded
• Doubt requires a framework and a context to make sense
• Universal doubting would undermine meaningful doubting
• Meaningful doubting must occur within a system where things are not doubted

5. Language games and Framework
• Certain propositions must be held fast within a language game (not questioned)
• Bedrock beliefs allow for the possibility of language and meaning
• Like the rules of chess, the pieces, and the board they provide the background for the game to be played

6. The Nature of Hinges
• They can be pre-linguistic or animal beliefs
• Hinges can be pre-linguistic rather than propositional
• They can change over time, although some are more permanent than others
• They can vary due to different systems of belief, though some core hinges are universal

7. Implications for Epistemology
• Challenges traditional epistemology that all beliefs within an epistemological framework require justification
• Some beliefs make justification possible
• Helps to understand the limits of knowledge and doubt
• Demonstrates how certainty is grounded in action rather than a specific theory
Sam26 December 27, 2024 at 01:46 #955822
What might an outline of a theory of knowledge look like in my interpretation of OC?

A Layered Theory of Epistemic Foundations

1. Foundation Layer: Pre-linguistic beliefs or certainties
• Consists of pre-linguistic or animal beliefs or certainties
• Pre-linguistic beliefs are manifested through action
• E.g’s include special awareness, object permanence, and bodily awareness
• These form the foundations of what makes the language games of knowledge possible
• Not subject to claims of truth or falsity because they precede such concepts
2. Framework Layer: Hinge Beliefs
• Built on top of pre-linguistic beliefs
• This is the riverbed of our system of JTB
• Differing levels of stability
o Bedrock hinges (nearly immutable, e.g., physical objects exist
o Cultural hinges (can change over time)
o Local hinges (depend on contexts or practices)
• Not justified by evidence or reasons but shown through our practices
• Makes the language games of justification and doubt possible

3. Operational Layer
• Built on the foundation of hinge propositions
• Requires:
o Meaningful doubt
o Methods of justification
o Context within language games
• Subject to verification and falsification
• They can be taught and demonstrated

Key Principles:
1. The Doubt Principle
• The language game of doubt requires a stable framework
• Not everything can be doubted
• There must be practical consequences to doubt
• Doubt is necessary for knowledge claims

2. The Justification Principle
• Operates within language games
• Different language games require different forms of justification
• Justification ends with hinge propositions
• Justification cannot have an infinite regression

3. The Principle of Context
• Knowledge claims only make sense within the language games of epistemology
• Some propositions can be epistemological in one context and be a hinge in another

4. Principle of Practice
• Knowledge is demonstrated by practice and by our statements
• Actions are more fundamental than statements
• Learning involves the acquisition of explicit knowledge and implicit certainty
• Practice grounds theoretical knowledge

Methodological Implications:
1. Epistemology
• Understand how knowledge claims function in practice (language games)
• Examine the relationship between our actions and our certainties (beliefs)
• Study the many language games of justification across contexts
• Understand the importance of our background reality in knowledge

2. Scientific Knowledge
• Scientific methods rest on hinge certainties
• Paradigm shifts involve changes in hinges
• Understand the relationship between theory and observation

3. Everyday Knowledge
• Acknowledge the importance of practical knowledge
• Again, recognize the role of the inherited background
• Recognize the relationship between action and belief

This is a way of understanding knowledge within the context of some of Wittgenstein’s thinking in OC and the PI.

A lot more work needs to be done, but this is the beginning of how I think of epistemology using Wittgenstein as a catalyst for my thinking.

Some insights into Wittgensteinian hinges and Godel’s incompleteness theorems.

Extended Theory: Foundations of Knowledge and Formal Systems

1. Parallel Foundations

A. In Epistemological Systems:
• Hinge beliefs serve as unquestioned beliefs
• Pre-linguistic beliefs ground our knowledge
• Pre-linguistic beliefs enable the practice of justification

B. In Formal Mathematical Systems:
• Godel’s unprovable propositions function like hinges
• Some mathematical truths must be taken as bedrock
• Some mathematical statements are necessary for system operation but unprovable within the system

2. The Foundation Principle
• All systems whether epistemic or formal require unprovable foundations (hinges)
• Unprovable statements are not weaknesses but necessary features
• Hinges do not limit systematic knowledge but are a requirement for all systems of knowledge
• The attempt to prove every statement within a system leads to the following:
o Infinite regress
o Circular reasoning
o Foundational assumptions (hinges/axioms)

3. Unified Understanding of the Limitations of Systems
• Epistemological systems are built on hinges
• Formal systems have unprovable but necessary truths
• Both systems require the following:
o Statements that cannot be justified within the system
o Statements that are necessary for the system to function
o Statements that must be accepted rather than proved

4. Knowledge Implications

A. Mathematical Knowledge:
• Some mathematical propositions must function as hinges
• These are not problems for the system but features of formal systems
• The unprovability of certain mathematical propositions in a formal system mirrors the role of hinges in epistemic systems

B. Scientific Knowledge:
• Foundational assumptions are necessary for a scientific system
• These function like mathematical axioms and epistemological hinges
• They are necessary to scientific progress

5. Practical Applications:

A. In Mathematics:
• Recognizing certain mathematical propositions as hinge like
• There are limits to formal proofs
• Recognizing the role of bedrock statements

6. Philosophical Implications

A. For Knowledge
• Knowledge doesn’t need complete proof
• Systems are reliable despite having unprovable elements
• Foundational elements and proofs have different functions

B. For Truth:
• What we accept as true can exist independent of provability
• Some truths must be simply believed without proof
• What we accept as true is not always provable

7. Integrating Epistemological and Formal Systems

A. Common Features:
• Unprovable foundations are necessary
• Accept starting points
• Seeing limitations as enabling features

B. Differences:
• Understanding the properties of foundational elements
• Different methods of verification
• Different types of knowledge acquired

Understanding this integration suggests the following:

1. The limits Godel discovered in formal systems coincide with the role of hinges in epistemology
2. Mathematical and JTB necessitate unprovable foundations
3. These are features of these systems, not problems to be solved
4. Having a clear understanding of these systems helps to better understand both domains

As far as I know, no one has made this connection, viz., between hinges and Godel's incompleteness theorem.
Sam26 December 28, 2024 at 17:02 #956155
I’ve been thinking about expressing Wittgenstein’s hinges in terms of types.

For example…

1. Types of Hinges

• Pre-linguistic beliefs (shown in our actions)
1. Spatial awareness
2. Continuity of objects
3. Causal relationships

• Rule-based hinges
1. Rules of chess
2. Mathematical rules/axioms
3. Any defined practice

• Varied hinges
1. Physical facts (“This is my hand”)
2. Social conventions
3. Rules of language

• Chess example
1. The rules can be learned as statements
2. However, their role as hinges is learned from:
a) Accepting their use in practice
b) Their role as enablers of the game
c) Their status as foundational

• Wittgensteinian Insight
1. Hinges have a particular function
a) Foundational framework
b) Beyond doubt in practice
c) Necessary for activity (science, linguistics, games, epistemology, etc)
d) Must be accepted to participate in the activity

Sam26 December 29, 2024 at 22:36 #956485
In Wittgenstein’s final work, OC, he grappled with the fundamental ideas of knowledge (JTB), certainty, doubt, truth, and others. This was in response to G.E. Moore’s claims about what we can know with certainty. This led to what many philosophers refer to as hinge propositions. Hinge propositions can be referred to in several ways including bedrock, foundational, or basic beliefs; however, no matter how you refer to them they raise important questions about the foundations of knowledge, i.e., our epistemological practices.

One issue (among others) that emerges with hinge propositions within epistemology is understanding their relationship to truth. Propositions traditionally are thought of as either true or false. It seems clear that Wittgenstein is separating the traditional view of what we mean by proposition, with a more nuanced view given Moore’s propositions. For example, “If true is what is grounded, then the ground is not true nor yet false (OC 205).” This suggests that what separates hinges from other propositions is their role, viz., that they are foundational or bedrock. This bedrock status is what separates them from traditional propositions. “I should like to say: Moore does not know what he asserts he knows, but it stands fast for him, as also for me; regarding it as absolutely solid is part of our method of doubt and enquiry (OC 151).” The implication is that it is not justified or true because of evidence or reasons, but it is part of our method of inquiry that certain hinges (beliefs) stand fast. This is borne out in our forms of life. Our world picture comes before our talk of true and false. We inherit our background, it’s not a matter of it being true or false. The ground is what enables epistemological claims, which by definition include truth claims.
We can think of this as a kind of logic of precedence, i.e., before we can say anything we need a framework, shared practices, basic (subjective) certainties, and ways of judging. The ground is not yet true or false. In other words, hinges, which are the ground, are not true or false in this setting. This is simply the way I act, whether linguistically or otherwise.

We can think of the use of true in the same way we think of the use of know. For example, just as “know” can be used as an expression of JTB and as a conviction of what one believes, so the use of “true” can be used apart from its epistemological uses. This insight helps to explain Wittgenstein’s reference to the truth of 2+2=4. These basic mathematical statements, especially when functioning as hinges operate more like rules of practice, something akin to a rule of chess. They demonstrate how we operate with numbers rather than making truth claims. However, it depends on the language game or the context. Certainly, there are proper uses of “true” outside the context of epistemology, just as there are proper uses of “know” outside epistemology. The use of “know” has this dual nature, so too does the concept of “true.” The context of the language game is what drives the correct use.

Given that Wittgenstein never completed OC the term hinge proposition itself might be problematic. Alternative terms like bedrock beliefs, foundation beliefs, or basic beliefs might be better suited to capture their pre-propositional nature.
Sam26 January 02, 2025 at 20:07 #957705
So, hinge propositions (bedrock beliefs) are outside our epistemological framework (JTB), which means that hinges aren't known in the epistemological sense, i.e., they are not justified and true. I say, "epistemological sense" because there are language games where using true about hinges can make sense. However, it's not an epistemological use. One can see this if, for example, we look at the rules of chess, which are hinges. There is no objective justification for saying that bishops move diagonally, i.e., there is no objective justification that leads me to the truth of the statement that bishops move diagonally. The rule is just an arbitrary backdrop or a matter of convention that we accept. Does this mean we can't use the word true about these rules, of course not. We accept them as true, but not epistemologically. For example, it's similar to the use of know that's not epistemological. Moore's use of "I know this is a hand," is the classic example, it's not an epistemological use in the context Moore is using it. His use of know is akin to a conviction, it's not epistemological. The word true can be used in the same way, as an expression of an inner certainty. Is it true that bishops move diagonally? In other words, is the statement "Bishops move diagonally" justified and true? No. It's a rule we accept that is foundational to the game. Are there instances where the "Bishops move diagonally" is justified and true? Yes. It depends on the context of the language game. People tend to conflate this distinction.
Sam26 January 03, 2025 at 00:04 #957774
Let me explain this idea more simply:

Again, thinking about the rules of chess. When we assert that "bishops move diagonally," this isn't something we prove or justify, it's just a rule we accept to play the game. It's like saying "This is how we move the piece," how we act when we play the game. We can say that it's true that bishops move diagonally, but this is different from saying that it rained yesterday, which we can defend by looking at the weather records and other evidence.

Imagine trying to prove that you have hands in a context similar to Moore's example. It would seem ridiculous because it's not something we normally need to prove. The subjective certainty we have about our hands is very basic, it's like the chess rule - we start with it, we act with our hands and we play chess using the rules of chess. We don't prove these things.

The key point is that some things in life aren't things we know in the JTB sense. They are the foundation that lets us know in the epistemological (JTB) sense. In other words, you have to accept the rules of chess before you can play the game, and there are certain things you have to accept about the world before you can start making knowledge claims.

We often use words like true and know in different ways. When we say, "I know my name," we're not really offering a proof, we're just expressing a basic certainty. It's different from saying the Earth is the third planet from our Sun, which we can prove by observation. Much of the confusion stems from the different uses of these words (true and know), some are foundational (hinges), and others are not.
Sam26 January 04, 2025 at 04:37 #958073
The Practicality of Understanding Hinges

Wittgenstein's hinge propositions (hereafter known as basic beliefs) from On Certainty offer profound insights into how everyday life connects with intellectual pursuits. The ideas contained in OC extend far beyond philosophical theory, reaching into reality on a practical level, namely, how we learn, know, and act in the world. One example of this is how we teach a child. We don't start by proving fundamental facts about reality - we show them how to interact with the world, which is closely connected with our forms of life. A child learns this is a hand not by proof, but by interacting with the world, non-linguistically or linguistically. This practical subjective certainty provides the foundation for later learning, especially the more advanced concepts of knowledge and doubt. We teach a child how to follow the rules of mathematics, we don't prove that 2+2=4. We show them how to count, and we show them how to interact in the world by using mathematics. They learn the basic beliefs of mathematics first. The certainty they acquire is through practice and participation in our forms of life. A child doesn't start by questioning these basic beliefs. For example, they don't question if a word refers to some thing, they start by learning the language games of the concepts. Questioning and doubting come later in the more advanced language games after the foundation has been put down.

Basic beliefs are why scientists don't question everything. There's a certain set of basic beliefs that stand fast in order for scientific investigation to proceed. A biologist doesn't question the existence of the microscope, they simply use the microscope. Basic beliefs make scientific investigations possible.

Wittgenstein's basic beliefs explain why there are cultural differences, viz., some cultures have different sets of basic beliefs. This is true even if some core basic beliefs are shared between cultures. This is also true of religious beliefs; each religion has its own basic beliefs within its religious system. This doesn't mean that all basic beliefs are equal, some are absolute (like there are other minds), and some change because they're challenged.

There are obvious implications for how we understand knowledge. Instead of seeing basic beliefs as requiring justification, we recognize that some certainties (basic beliefs) must stand fast in order for epistemological justification and truth claims to be possible in the first place.

These insights demonstrate that our relationship with reality isn't primarily theoretical but practical. This doesn't diminish philosophical inquiry; it just puts it in the proper light.

This is slightly different but related. The rules of chess do not describe the truths of reality in the same way that "water freezes at 32 degrees F" does. Instead, they constitute the very framework within which true and false (correct and incorrect) can be assessed


Wittgenstein seems to suggest that the intelligibility of ‘water boils at 100 C.’ depends on such a bedrock of hinge propositions ( a ‘whole way of seeing nature’).


291. We know that the earth is round. We have definitively ascertained that it is round. We shall stick to this opinion, unless our whole way of seeing nature changes. "How do you know that?" - I believe it.
292. Further experiments cannot give the lie to our earlier ones, at most they may change our whole way of looking at things.
293. Similarly with the sentence "water boils at 100 C. (On Certainty).

Reply to JoshsOC 291 is just Witt reiterating that some truths about the world are just part of the framework or foundation of understanding. They're not questioned or doubted. I just believe it, i.e., I believe it's true without justification.

OC 292 - Our knowledge is part of an enormous system and the value of our beliefs or knowledge takes place in the broader system of beliefs and practices.

OC 293 - Again, some basic beliefs must remain fixed for practicality and if they didn't, we wouldn't be able to act effectively in the world.

One can look at these basic beliefs as foundations for action, both in linguistics and epistemology. This is why I think Witt is just giving us a foundation for our beliefs to stand on, but it's not a traditional foundational view.

But they not just undoubted foundations. They are systems of significations which act to qualitatively organize facts in a certain way, with a certain sense. These foundations can be turned on their head, and then the facts become organized in a completely differently way, revealing a completely different sense of meaning, as when paradigms shift. Turning the foundation on its head isn’t doubting that foundation or making it false. It’s changing the rules of intelligibility. It’s not just that I beleive it’s true. I believe what is true according to a certain arrangement. I doubt particulars organized within a system of sense. The system of sense does not itself change by being doubted, but by ‘changing the subject’. Similarly, with the duck-rabbit drawing, I can’t doubt whether what I am seeing is a duck rather than a rabbit. When what I see appears for me as duck I am simply certain of it. I don’t switch from seeing the duck to seeing the rabbit by doubting the duck. I do so by seeing under a different aspect.

I believe water boils at 100’degrees the way I believe what I am seeing appears to me as a duck. For the drawing to no longer appear to me as a duck, the whole system of component parts will have to undergo a re-organization. For water no longer boiling at 100 degrees to make sense will imply a total re-organization of the underlying paradigm.

Banno January 10, 2025 at 23:51 #959674
100? counts as the temperature at which water boils at sea level. That's not an observation about how the world is, but a way of setting up a language game that talks about temperature. One cannot be mistaken about water boiling at 100? or about ice melting at 0?; 100? is the temperature at which water boils and 0? is the temperature at which ice melts. These are examples of hinge propositions.

To doubt that water boils at 100? is not to doubt some observation, but to fail to understand what 100? is.

And again, it is a mistake to think that these propositions are not true. If they were not true, we could not use them to make observations or deductions.

Reply to BannoYou didn't direct this at me, but I wanted to respond.

Yes, they're examples of hinges. However, certain hinges (basic beliefs) provide the framework for the language games of epistemology to work. There is no mistake here about truth, it just depends on the language game being used. It appears that you're lumping all language games about truth into a single mix. Moreover, hinge propositions are not normal propositions, if they were he wouldn't have singled them out. So, in what sense are they true? You seem to ignore the examples I gave that point out how they can be said to be true, and the ways they cannot be said to be true. Maybe you can clarify.

Trouble is that language games are not discrete.

It is true that the bishop never changes from the colour square it starts on; this is a consequence of the hinge propositions that set the game up. If these hinges were not true, then we could reach no such conclusion about the bishop.

If it appears that I lump all language games about truth into a single mix, that is becasue the games around knowledge and the games around truth are not unrelated. One can only have justified true beliefs if there are truths.

And if hinge propositions are not normal propositions, they are not abnormal, either. There is nothing deviant or undesirable in their use. Rather than being distinct from epistemology, hinges are foundational.

I like the rest of what you said, but could you clarify the above? Sam26 pointed out in an earlier post that the sense of ‘ know’ and ‘true’ are not the same for hinge propositions as for particular facts within the games that they set up. Do you agree with this, and if so, how would you characterize the distinction between the sense of ‘true’ with regard to a way of setting up a language game and an observation within that language game? For instance, I would argue that observations are true or false, but language games are true or unintelligible. Unlike an observation within a language game, the language game itself cannot be true as opposed to false. It makes no sense to declare a language game false, only unintelligible.


Banno January 11, 2025 at 03:22 #959718
Reply to Joshs It's a simple and fairly direct point. If a proposition is to function as an assumption in an argument it must have a truth value. So if hinge propositions are to "ground" our deductions, they must have a truth value.

Here is a hand. Therefore there are hands. f(a)??(x)(fx).

So "here is a hand" must be true.

I don't know what to make of "the sense of ‘ know’ and ‘true’ are not the same for hinge propositions as for particular facts within the games that they set up". I don't see that we need say there is a different sort of "true" for hinge than for other propositions. And if Wittgenstein is right then we cannot properly be said to know hinge propositions, since they cannot be doubted; and if that is so, then what is one to make of saying we know hinge propositions in a way that is different to other propositions?

So I do not see that there is a "distinction between the sense of ‘true’ with regard to a way of setting up a language game and an observation within that language game".

And language games are played or not. I don't know what to make of saying that they 'are true or unintelligible'. If a language game were unintelligible, what grounds could there be for claiming it was a language game at all? (Davidson, again).

So I'm not sure how to respond to your post.

These foundations can be turned on their head, and then the facts become organized in a completely differently way, revealing a completely different sense of meaning, as when paradigms shift. Turning the foundation on its head isn’t doubting that foundation or making it false.


Turning the foundation on its head requires doubting it. Only by doubting it, will we seek a better way. We will never "change our whole way of looking at things", unless we first doubt our current way of looking at things.

So for example, Witt says "water boils at 100 C". But @Banno qualifies this with "at sea level". The need for such a qualification gives reason to doubt the original way of looking at things, "water boils at 100 C". The skeptic might then propose the hypothesis that the boiling of water is a feature of environmental pressure rather than a feature of the internal temperature of the water, and experiments could be carried out accordingly. If the experiments confirm what is proposed, this could lead to us changing our way of looking at things, that foundation would be overturned. But this cannot occur without doubt, so doubt is an essential feature of shifting paradigms (ways of looking at things).

It seems that you and I read Witt in alignment with different communities of interpretation. The group I identify with believes that all uses of conceptual meaning produce senses of meaning. No word concept can have only one sense of meaning associated with it. If I say that something is true, it always must be asked in what sense , what context of use, within what language game I mean to use this word. This goes for the concept of ‘truth value’. To state that a truth value is a property of propositions that function as assumptions in an argument is to lay out the terms of a language games. Certain bedrock assumptions
must be in place in order for this game of true-false to be intelligible, and such assumptions are not themselves amenable to ascertainment of truth value.

I ‘know’ this is my hand says that the proposition ‘this is my hand ‘ makes sense to me in a particular way, within a particular language game. I have learned how to see that world a certain way.

Reply to Joshs So, what would a logical argument look like in favor of my interpretation of Wittgenstein’s hinge propositions?

P1: All knowledge in the traditional epistemological sense requires justification, truth, and belief.
P2: Hinge propositions, do not require (or cannot undergo) justification since they are bedrock.
C1: Therefore, hinge propositions do not fit into the traditional knowledge model (from P1 and P2).
P3: If something does not fit into the model of knowledge where it must be justified to be known, then based on JTB, it is not "known."
C2: Hence, hinge propositions are not known in the epistemological sense (from C1 and P3).
P4: If something is not known epistemologically, it does not meet the criteria of being justified or true in the traditional sense.

Reply to Sam26

I think your conclusions work fine. A lot of philosophy would take issue with P1 and P4 (is P4 supposed to be a conclusion rather?).

Wittgenstein stays within his narrow analytic context (since he never much ventured beyond it), but the idea that:

A. Knowledge is belief.
B. That truth (particularly in a "traditional sense") requires justification.

Are both historically hotly contested issues. For the Platonic and Aristotelian traditions for instance, knowledge cannot be belief. If it was, this would lead to all the problems of representationalism and towards universal skepticism (of the ancient sort). Knowledge is, for them, rather the co-identity of the intellect and the intelligible that is known.

Or, in the mutable realm, we could consider how "acquiring carnal [I]knowledge[/I]" of another man's wife was considered a sin that had nothing to do with belief.

Then, more broadly, and more popularly in the modern context, truth is something like "the adequacy of intellect to being." But such adequacy, while it might itself be known through justification, is not defined in terms of justification and does not require it as some sort of "prerequisite."

And then if "justification" is meant to be something like: "moving from premises to consequents" in speech, propositional thought, writing, or formal logic, there will be further disagreement. Just for one example:

...neither are all things unutterable nor all utterable; neither all unknowable nor all knowable. But the knowable belongs to one order, and the utterable to another; just as it is one thing to speak and another thing to know.

Saint John of Damascus - An Exposition of the Orthodox Faith



Now John of Damascus is a saint for both Catholics and the Orthodox, but you'll see ideas like this (and going further) embraced a lot more in eastern thought, and it leads to a much different view of justification. Whereas the cataclysmic Wars of Religion that rocked Latin Christendom elevated a very specific sort of rigorous, legalistic, and above all written/deductive form of "justification" as the norm.

Of course knowledge must be true. A true belief is a belief though. The contested position would be that knowledge is merely (justified) true belief.

If knowledge is just belief, and one can never "step outside belief" to compare belief with the subjects of belief, then all knowledge is uncertain. This problem (and related infinite regresses of representations) are why correspondence definitions of truth had a nadir from late antiquity to the early modern period, and why folks like Hegel still vigorously object to them.

The idea that it's absurd to say one "knows" that one has a toothache suggests that "knowing" is about justification. The idea that one can (indeed, just be able to) doubt anything one "knows" also makes it pretty clear that "knowledge" here is something like belief.

When he is talking about how it is nonsense to discuss whether a rod does or doesn't have length, or asking "are there physical objects," the key idea seems to be that knowledge involves both belief and verification. I don't think Sam is wrong on this interpretation (as noted, I do think many—on solid grounds—might reject Wittgenstein's premises.)


1. Where in the grammar of ordinary language do we find the idea that knowledge is justified true belief?


I don't know if we do. It probably varies by time and epoch as well. When someone says: "I know what it is like to lose a parent," they aren't talking about affirming the proposition that one of their parents has died, for instance. And "to know someone well," doesn't seem to be [I]just[/I] to have a lot of true beliefs about someone. We might have many true beliefs about someone we have never met and claim not to know them.

...is spot on. "I know that this is my hand" is quite clear and correct English. If we are to look to use instead of meaning, then "justified true belief" might give way to a more nuanced account.

Well, no. We do assign truth value to some propositions, but we also work out the truth value of other propositions. Not all assumptions must be hinges.


To be clear, when I equated ‘stating a truth value as a property of propositions that function as assumptions in an argument’ with ‘laying out the terms of a language game’,I didnt mean that all language games are expressible in terms of presenting a truth-apt argument. That is, I dont believe that ‘language game’ is just another word for a ‘proposition with truth values’. They are not the same thing. The latter is subordinate to the former, in the same way that moves in a chess game are subordinate to the rules of chess, and the rules of chess is just one among many possible language games. I’m equating a truth-apt propositional argument with the moves of chess, not with its underlying rules , and certainly not with the nature of language games in general. The underlying rules of a truth-apt argument are not reducible to formal logical notation such as ‘Here is a hand. Therefore there are hands. f(a)??(x)(fx).’ The bedrock of underlying assumptions making truth apt arguments intelligible don’t , and can’t, look like any statement in formal logic. A system of bedrock convictions is a gestalt structure of interdependent meanings.


141. When we first begin to believe anything, what we believe is not a single proposition, it is a whole system of propositions. (Light dawns gradually over the whole.)
142. It is not single axioms that strike me as obvious, it is a system in which consequences and premises give one another mutual support.
410. Our knowledge forms an enormous system. And only within this system has a particular bit the value we give it



Furthermore, because the system of convictions underlying the intelligibility of truth apt statements is only one particular language games among many possible games, one can no more use truth apt arguments to express language games in general than one can use the rules of chess to express any and all languages games.

Would you say that deciding to change the rules of chess in order to make a more interesting game is an example of ‘doubting’ the current foundation of chess?


I think there is a need here to distinguish between essential and accidental properties, as a way toward understanding this question. If we say that every single rule is essential to the game known as "chess", then changing any one of them would render the new game as no longer "chess". We'd then say that any such change affects the foundation. But if, for example, we designate only the position of "check" as essential to the game, then we are free to make all sort of rule changes, still call the new game "chess", and say that we have not doubted "the foundation".

So it all depends on what is determined as "the foundation". I believe that in many conceptions, there is no such thing as "the foundation", because numerous essential aspects are brought together, therefore numerous foundational aspects. Doubting, and changing aspects of a conception generally alter the conception by degree. However, I believe that we do have to acknowledge the reality of foundational aspects, such as when we turn things right around, like the change from the geocentric to the heliocentric model. Clearly the foundational belief was doubted.

Imagine if we turned the game of chess right around, so that each player started in an equal position of checkmate, with some pieces already taken off the board, and the players were allowed to move other pieces while the king was checked, and the goal was to get all the pieces back to what is now the starting place. This would render the check position irrelevant, and that change would clearly be the result of doubting the foundation, because "the object" of the game would be completely changed. In this case we can say that when the conception of "the object" is doubted, the foundation is doubted.
Sam26 January 12, 2025 at 14:53 #960003
If read closely, much of what I've written implies that Wittgenstein's OC enhances the traditional view of knowledge as JTB. I believe that JTB is still a good definition, but given OC, it needs a bit more nuance. Let me be a bit more precise about my view of JTB given the backdrop of OC.

So, integrating JTB into OC involves rethinking how we use justification and truth, and how we think of beliefs. For example, justification often focuses on logic or rational argument, but Wittgenstein's approach is more practical focusing on the various language games within our forms of life. Also to acknowledge the limitations of justification as foundational or bedrock to our whole system of knowledge. Thus, what constitutes justification is based on the context of the language game being played. To understand this requires a good understanding of Witt's views in the PI.

My approach to truth is that it's more about their role in different language games. So, one role is that statements can be true as part of a framework, like the role of hinges or the role that rules play in a game. These are not truths that are justified, but truths that are part of our background certainty (and they can be used as propositions in an argument).

The other predominant role of truth is those that are justified, these are epistemological, i.e., they are used in our language games of epistemology. So, I don't think the use of truth is restricted to the language games of epistemology. I guess this is a dualistic approach to truth.

You can think of traditional JTB as being enhanced by OC. First, with the base layer of hinge propositions (or as I like to say basic beliefs or basic subjective certainties). In this layer justification and truth are about their role in our system of epistemology, viz., they're bedrock to our system of epistemology. In other words, they allow the language games of epistemology to take root.

The upper layers above the base layer (bedrock) are more akin to the traditional language games of JTB. This is where the typical role of inference takes place.

Then there is the role of skepticism in all of this or the role of doubting. Some claims don't need to be justified in response to skeptical doubt because they are part of what makes doubting possible.

This view of knowledge (JTB) is more holistic and is connected to a web of beliefs, practices (forms of life), and language games. So, JTB is enhanced by Wittgenstein and how it correlates with our practical life, viz., how we act (linguistically and as we move in the world).

By integrating these ideas the traditional model of JTB can be enhanced.

So, whenever I use JTB this is what I think about.

A language game like chess has built into its assumptions the looseness of the relations among its rules. This looseness is what makes it permissible to tinker with individual rules without making the game unrecognizable or incoherent. What is considered accidental and what is essential is itself specified by the structure of the language game of chess.

However, I believe that we do have to acknowledge the reality of foundational aspects, such as when we turn things right around, like the change from the geocentric to the heliocentric model. Clearly the foundational belief was doubted.
Imagine if we turned the game of chess right around, so that each player started in an equal position of checkmate, with some pieces already taken off the board, and the players were allowed to move other pieces while the king was checked, and the goal was to get all the pieces back to what is now the starting place. This would render the check position irrelevant, and that change would clearly be the result of doubting the foundation, because "the object" of the game would be completely changed. In this case we can say that when the conception of "the object" is doubted, the foundation is doubted


Wiitgenstein uses the word ‘doubt’ to indicate a situation where some particular feature within a language game is put into question, while leaving the game intact. This is why he says that some beliefs must be left certain in order to doubt anything. We can’t doubt the geocentric model by switching to a heliocentric model unless the two models have features that can be incorporated under the same language game.

My approach to truth is that it's more about their role in different language games. So, one role is that statements can be true as part of a framework, like the role of hinges or the role that rules play in a game. These are not truths that are justified, but truths that are part of our background certainty (and they can be used as propositions in an argument).


You say that the system of convictions that form the background certainty of a language game can be used as propositions in an argument . Banno says the kind of propositions that the ‘truths’ of a background system of convictions can be used as are those which assign a truth value. Do you agree with him? If not , what kind of propositional argument can these truths be used as? Can you give an example? I have problems with calling a language game an ‘argument’. What kind of argument is a form of life? If we try to persuade someone to adopt our way of seeing, are we presenting an argument or is our way of seeing the condition of possibility for arguments? Isnt the language game the bedrock, the groundless ground for arguments and the point where arguments end?

105. All testing, all confirmation and disconfirmation of a hypothesis takes place already within a system. And this system is not a more or less arbitrary and doubtful point of departure for all our arguments: no, it belongs to the essence of what we call an argument. The system is not so much the point of departure, as the element in which arguments have their life.


By this, Wittgenstein doesn’t mean that the elements of the background system form a meta-argument, but that they are not of the order of an argument at all.

Sorry Josh, but I never said anything about a "system of convictions." You're confusing what I said about Moore's use of "I know..." (which is more like an expression of conviction as opposed to knowledge) with the framework of reality, made up of basic beliefs or certainties.

The statement, "I believe this is a hand," can be said (I don't like the term 'truth value') to be true in some language games. It's comparable to saying "It's true that bishops move diagonally." These are just certainties that grow out of very basic beliefs about our foundational background. For example, part of the background reality of chess is that there are rules, pieces, and a board, and it's this background that allows for the game of chess. In the same way, basic beliefs (hinges) are basic beliefs about our background (beliefs like "we have hands" "there are other minds" etc) - this background is necessary for the language games of knowledge and doubt to take place. This doesn't mean that basic beliefs can't be referred to as true, just not in combination with being justified, i.e., justified and true. So, you can't on the one hand believe that the foundation is not justified (i.e., hinges) and on the other say they are justified. It's necessarily the case that hinges aren't justified - that's the whole point of Witt's argument.

I believe that JTB is still a good definition, but given OC, it needs a bit more nuance.

But did Wittgenstein continue to believe it was a good definition?

"Don't think, look!"

"I know I have a toothache - how silly of you to suppose otherwise!". "I know where my hand is".

These look to be reasonable, straight forward uses of "I know..." and yet they are problematic for the JTB account. The use of "I know..." is broader than the JTB account sanctions. The game is played, in such a way that the JTB account is inadequate to explain it.

I had my tonsils out and was in the Evelyn Nursing Home feeling sorry for myself. Wittgenstein called. I croaked: I feel just like a dog that has been run over. He was disgusted: “You don't know what a dog that has been run over feels like.”


Would he also say that you don't know that you have a toothache?

And if he did, would he be right? Or would he be delineating "know" in an arbitrary fashion, against his admonition to look to use?

You seem to not acknowledge that there are uses of "I know..." outside JTB, i.e., they have nothing to do with JTB. For example, "My having two hands is, in normal circumstances, as certain as anything that I could produce in evidence for it. That is why I am not in a position to take the sight of my hand as evidence for it. Here the expression 'I know' stands for the conviction [my emphasis] that this is so (OC 86)."

Someone is trying to learn the rules of chess. They are afraid they are getting it wrong, so they ask if it is true that bishops move two squares up and one step over. Even as they ask this, they doubt that they have it right. Notice how in this example, it makes sense to talk about true vs false and doubt. But what is one doubting, what is one getting wrong, the language game of chess? But that can’t be, because it doesn’t make sense to doubt a language game. So what is true or false, or to be doubted, about the statement ‘bishops move diagonally’ if not the rules of chess?

Isnt my telling someone their belief that ‘bishops move two squares up and one step over’ is false akin to the adherent of an heliocentric account telling the adherent of a geocentric account that their belief is false? In both examples, aren’t the concepts of falsity and doubt misplaced? We act as though believing a bishop moves two squares up and one square over is incorrect in the same way as miscalculating the product of 25 x 347, when in fact it is an example of producing rules of a different language game than that of chess.

You are neglecting the qualification "at sea level". That qualification indicates two essential conditions, temperature and pressure. So, the statement "water boils at 100 degrees" is in fact doubted by the addition of that qualification. However, the language game remains intact, only slightly changed by that doubt. If however, as in my example, it turns out that water boiling is completely a feature of external pressure, and internal temperature was just a ruse, then we'd want to rid ourselves of that language game, as being a faulty representation.

Obviously, I do not accept the common interpretation of how Wittgenstein portrays "doubt". I believe that we can and do doubt foundational rules. And, I also believe that the foundational aspects of the geocentric model were doubted, and this doubt is what allowed it to be replaced by the heliocentric. So I think it is very clear that we do doubt foundational aspects, and completely destroy important conceptual structures, even though vestiges of the old may still remain in our language games ("the sun rises", "the sun sets"). These vestiges become metaphors, so sometimes instead of ridding ourselves of the faulty language game, we allow it to remain in the form of metaphor.

Reply to Banno

suggests that Wittgenstein had the contestable view that knowledge is the very same as belie


I agree, it might suggest this if I had only written the quoted part and not clarified in the next paragraphs. Nowhere though do I suggest that the problem is that "not all beliefs are true and justified," but rather that belief does not imply identity between the intellect and what is known, and does not capture what is meant by many uses of "to know" (e.g. sensing as knowledge, to "know how to ride a bike," or the original example of "carnal knowledge,")

But one must surely believe what one knows? "I know it's raining, but I don't believe it!" is ironic? A play on our expectations?


People speak this way without irony all the time. "So you believe you could have fixed the problem?"

"No, I [I]know[/I] I could fix it."

People often get offended when their knowledge is impugned as mere belief/opinion.

Of course one affirms what one knows. So yes, it wouldn't make sense to essentially affirm and deny the same thing. Generally, the distinction involves [I]understanding[/I], a grasp of the thing known, as opposed to merely holding a justified opinion that also happens to be true.

For instance, does one "know Jimmy Carter," if one affirms some justified beliefs about the man but has never met him? Certainly one doesn't "know how to fix a car" or "train a horse," or "know horses" through merely holding justified true opinions about them, and the same goes for "knowing what coffee tastes like." And we might question if one "knows justice" or "what is just" by being able to affirm informed, true opinions about just action.

English is hardly unique in its many senses of the word to know. Attic Greek, for instance, offered up distinctions between sophia, gnosis, techne, episteme, phronesis, and doxa. And no doubt, there is plenty of analytic thought, particularly more recently, that pays particularly close attention to the distinction between "knowing that" and "knowing how" (and even "knowing why").

The question is which sort of knowledge is paradigmatic of knowledge in its fullest sense (or maybe none and we have a sui generis plurality?) In general, justified true belief has, in part because of the particular philosophy of language and rationality in vouge, tended to focus on the justified/informed affirmation of true propositions.

However, it seems fair to question if the horse tamer and the horse researcher, who both read on and spend their lives with horses, might [I]know[/I] horses in a way that someone who has simply read some books on them (and so holds justified, true beliefs) does not. I suppose the philosophy of perception/imagination is relevant here too.

A big issue in OC is precisely what comes up when all knowledge is demonstrative knowledge. This problem is an old one. In this case, an infinite regress of (circular) syllogisms would be required.
Count Timothy von Icarus January 12, 2025 at 22:36 #960202
Anyhow, hinge propositions obviously aren't arbitrary. Why do disparate cultures share so many, e.g. "we have bodies," and "there are corporeal objects?" A shared human "form of life," perhaps. However, that term is quite ambiguous. One might suspect that such propositions are accepted rather because they involve non-demonstrative knowledge.

But then the knowledge is in some sense prior to and constitutive of the language.

Perhaps, depending on how "belief" is defined. If belief is just something like "the affirmation of a proposition," then one would always believe what one knows (although we might say that it is things/principles that are primarily known, not propositions).

This doesn't suggest that knowing is a form of believing though. Whenever one is running, one is also breathing, but running doesn't consist in breathing. Similarly, swimming entails but does not consist in not drowning. In the same way, belief might go along with knowledge without being what knowledge consists in.

The point here to work through the various ways in which "I know" is used? it would be prejudicial to supose that any was paradigmatic.

I've been tweaking my idea of bedrock beliefs as a replacement for Wittgenstein's notion of hinge proposition. Instead of bedrock beliefs which sound too personal and don't convey the shared nature of these beliefs, I've changed the wording to capture both the personal and their shared nature. A name that seems to fit this idea more appropriately is bedrock convictions, which capture their personal and shared nature. Personal in that all of us have these convictions and shared because all of us share these convictions as a necessary part of life and language. For example, as individuals and as part of a community we act with our hands is a conviction that stands as a necessary part of our background. I don't say "I have hands" before acting, I just act. So, our acting is at the bottom of the language game (OC 204).

Bedrock convictions (hinges) are also split into prelinguistic convictions and linguistic convictions. Prelinguistic convictions are shown in simple actions like picking up an object which reflects the conviction that I have hands. Our actions show these convictions apart from language, but they can also be expressed as part of language, however, language comes later. As language forms it will convey another layer to these convictions, viz., linguistic convictions, such as the rules of chess. Prelinguistic convictions are not subject to doubt because the use of the concept of doubt is a linguistic function (it's not necessarily a linguistic function, although the concept is) especially as part of Moore's argument and as part of the skeptic's argument. The prelinguistic props up the linguistic. It would be logically impossible for the latter (linguistic convictions) to exist without the former. This is why the skeptics' doubting is nonsense. We don't start with doubts, we start with subjective and collective certainty that enables the language games of JTB and the language games of doubting.

I'm further arguing that Wittgenstein's hinge propositions are probably a necessary function of Moore's reference to his statements as propositions and not so much that Wittgenstein thinks of them as traditional propositions. This seems obvious given Wittgenstein's reference to Moore's statements as hinges. But there is an important point that Wittgenstein's writing alludes to, viz., that hinges are not true in the traditional epistemological or propositional sense. In other words, they don't carry truth values in the same sense that traditional propositions do where they're open to verification or falsification. Bedrock convictions aren't subject to the justificatory machinery of JTB. They are the frame that stands fast for the machinery of JTB (JTB for me consists of different language games in the Wittgensteinian spirit). So, the truth of bedrock convictions is tied to the language game of conviction rather than justification. Normal propositions (true and false propositions) are subject to justification and doubt, but bedrock convictions are not. I have the conviction that I have hands (shown in my actions), and this conviction expresses another use (another language game) of the concept true that is foundational to our systems of epistemology and doubt. The truth of bedrock convictions is a pragmatic and necessary one. They are structural.



Sam26 March 23, 2025 at 17:54 #978063
How would I explain Wittgenstein’s hinges to someone who never heard of Wittgenstein’s On Certainty?

Imagine trying to answer some question – like what’s true or what’s real, or whether you’re really sitting in a room typing. You ask yourself, “How do I know this?” or “How do I know that?” You’re like the kid who keeps asking “Why?” to every possible answer but never concluding because you’re in an endless loop of whys. You can’t seem to get anywhere because you can’t prove everything, no one can.

A philosopher named Wittgenstein who wrote about this kind of stuff said that there is a way to avoid this endless loop. His solution was that we accept certain basic beliefs without proof. He called these hinges, like the hinges on a door that allows them to open and shut. Without the hinges, the door falls off; without basic beliefs, language, and our thinking would similarly fail.

So, what are hinges? They’re everyday basic beliefs that we don’t usually question. For example, “The Earth existed 10 minutes ago,” or “I have hands.” These are the kinds of basic beliefs that we accept as true without normally requiring proof. We take them for granted because they’re part of how we live and act in the world. Wittgenstein pointed out that we need these kinds of beliefs to even start to ask questions or to figure things out. For example, before you open a door you don’t start wondering if the door exists, you assume it exists, and that's a hinge. It’s not like it’s magically true; they’re what we rely on to do the things we need to do. They’re like the rules of a game that we agree to accept to play the game. You don’t ask, “Do bishops move diagonally?” – everyone accepts the rule who plays the game that bishops move diagonally.

Another guy named G.E. Moore tried to say, “I know I have hands,” as if it was a matter to be justified or a matter of proof. Wittgenstein disagreed, saying that it wasn’t a matter of proof. He said that these beliefs were so basic that a proof wouldn’t make sense. Such beliefs are where questions begin. They are the foundation that supports what we know and doubt. Without hinges we would be confused, unable to reason or doubt. It would be like having a chess board and pieces but no rules. You couldn’t play the game.

"Here is a hand" is a proposition. It is not justified by some other proposition. It is a hinge proposition, one on which other propositions may turn.

That other propositions are dependent on hinge propositions is a piece of the puzzled that must not be lost. A hinge that is not a hinge proposition cannot fulfil this role.
Sam26 March 25, 2025 at 00:14 #978355
The difference between hinge propositions and typical propositions has to do with the role they play. Typical propositions are tied to states of affairs and assessed via justification. They’re players in the game, subject to the rules of truth and falsity (OC §243). Hinge propositions are foundational— truth is not a property they possess but a role in epistemological language games. They’re the rules or ground of the game, not subject to its moves (OC §204: “Our acting… lies at the bottom”). The idea of foundational convictions captures this idea.



Sam26 March 25, 2025 at 00:41 #978365
I've been trying to investigate whether anyone else has made the connection between Wittgenstein's hinges and Godel's unprovable statements. I think hinges provide a unique way of looking at Godel's theorems. They allow the system to work, just as they allow epistemology to work. They're unprovable, but system-sustaining. In other words, these are mathematical hinges. I think this idea of mine is original, as far as I can tell.

342. That is to say, it belongs to the logic of our scientific investigations that certain things are in deed not doubted.
343. But it isn't that the situation is like this: We just can't investigate everything, and for that reason we are forced to rest content with assumption. If I want the door to turn, the hinges must stay put.


Quoting Sam26
Hinge propositions are foundational— truth is not a property they possess but a role in epistemological language games.


And yet they are true. If they were not, then the door could not move, the investigation could not take place.

Sam26 March 25, 2025 at 00:55 #978371
Reply to Banno We accept them as true as part of a role. They're not true in the same sense that your typical proposition is. There is a difference between truth as a matter of fact or state of affairs, and truths that have a role that is arational and foundational. It's very much like accepting the rules of chess to play the game. Indeed, bishops move diagonally, but no state of affairs supports this rule. It's just foundational to the game of chess.
Count Timothy von Icarus March 25, 2025 at 01:00 #978375
Are propositions like:
"There is no such thing as noesis,"
"Truth is strictly a property of propositions,"
"Judgement is only proper to discursive reason, not to simple (reflexive) understanding,"
"Everything and anything is only intelligible and true or false as respects its context in a language or some belief system," ...
and the like hinge propositions for accepting a "Wittgensteinian epistemology," or does Wittgenstein's thought apply to all epistemology?

If "I possess a nous/intellect" can be considered on par with "I possess hands" then it would strangely seem that Wittgenstein's points simply wouldn't apply to those in the "I have a nous and am thus capable of intellectual apprehension," camp. Or would Wittgenstein's conclusions still hold true for [I]all[/I] "systems" (even those that deny that they are systems, or that knowledge primarily involves systems or language) regardless of hinge propositions?

If the latter, how could this claim to universality be justified? If it isn't justified, wouldn't it just be one of many possible hinge propositions?

I hadn't thought of it before, probably because I vigorously disagree with Wittgenstein's presuppositions, but I think it's possible that there is something self-refuting here, even when taken in its own terms. Or if not self-refuting, then at least self-undermining. The conclusions would be "what is true, given certain presuppositions." But then, many people think Wittgenstein's view of knowledge is pretty dismal, resting far from "certainty," (indeed, it wouldn't even be called "knowledge" in much thought) so why wouldn't we just reject those presuppositions and choose to "play a different game?"
Sam26 March 25, 2025 at 01:06 #978378
Reply to Count Timothy von Icarus The way you can differentiate between hinges and other typical propositions is that doubting them is generally senseless. Wittgenstein's hinges apply to all epistemology and any system of belief. "I possess intellect" could indeed be counted as a hinge, similar to we all possess consciousness.

Reply to Sam26

Yes, perhaps I wasn't very clear there. I meant an "intellect" in the classical sense (nous), as in "being capable of noetic intuition, a simple, non-discursive, reflexively known grasp of truth (i.e. one that is self-justifying because the knower is identical with the intelligible known)."

If this was true, then Wittgenstein's analysis of justification would have to be radically altered. Such a hinge proposition would be the difference between his conclusions re "where justification must end," and something like Aristotle's consideration of the same question in the Posterior Analytics (which comes to quite different conclusions).

Now, many justifications of noetic intuition or "transcendental apriorism" exist, but that is sort of beside the point. It can also be taken as a starting point (and indeed, often is in many strawman presentations of the tradition :rofl: ). But if it is taking as a starting point, the conclusions about truth and knowledge will look quite different.

This seems to me to introduce a sort of self-undermining instability into the epistemic conclusions drawn from the analysis.

Reply to Banno My point is trying to clarify different uses of truth in our language. And the difference in the roles of truth in our systems of belief. You are correct that there are different roles or layers of hinges. The rules of chess are hinges (foundational to the game), and "I have hands" is a foundational truth that stands outside of epistemological games.

Yes, my point was not that hinge propositions involve noesis (indeed, the concept presumes there is no such thing as noesis). Rather, it was that, for Wittgenstein's analysis to hold up, noesis must be denied as a possibility. It must be the case that we cannot possibly know truth as truth outside the context of discursive justification (or, on some later interpretations, that truth and knowledge are definable exclusively in terms of "systems/rules" of discursive justification).

Otherwise, if there is noesis, then there [I]can[/I] be knowledge of truth as truth without discursive justification (which is also not dependent on language). Noetic understanding is justified in that it knows itself as true (and indeed there are arguments that judgement is itself most proper to understanding and not reasoning/ratio, e.g. https://isidore.co/aquinas/english/QDdeVer15.htm, article I). But then beliefs regarded as "hinge propositions" might not be senseless to question, and might be very well "knowable" (given the far less restrictive definition of knowledge this opens up).

Or, perhaps one way to frame the presupposition that is needed would be to say "all justification for judgements lies in discursive reasoning/ratio, not simple understanding," with maybe the added caveat that "all justification makes use of language, and only occurs in this context."

But the existence of noesis itself seems like it could be the subject of a "hinge proposition." Yet if it can be, then Wittgenstein's conclusions themselves would only apply given certain hinge propositions.

Are the hinge propositions that hold up the analysis common to all, or at least most men then? It hardly seems that they can be given transcendent apriorism was the dominant epistemology for about two millennia.

This seems like a problem for folks like Rorty who would like to use Wittgenstein to say things about language and the possibility of metaphysics for [I]all[/I] of philosophy.

They are not different uses of "truth". They are different uses to which the proposition is put by the language game. Some propositions stand within the game, others set the game up. Those that set the game up cannot generally be doubted within the game. Hence the game hinges on them.

Reply to Count Timothy von Icarus Propositional truth is dependent on language, i.e., the concept is linguistic. You seem to point to some truths as metaphysical that we access intuitively. Hinge propositions arise in our acts (I'm referring to pre-linguistic hinges). For e.g., my use of my hand shows my belief that I have hands. This is different from what you're saying.

The propositions you're referring to are true because they refer to facts or states of affairs. In this sense they are justified, justification ends with hinges.

Let me explain it one more time why hinges aren’t propositionally true.

1. They’re not open to judgment – typical propositions like “It is raining,” are moves subject to true or false on evidence (OC 243 “compelling grounds”). Hinges are the board itself without the hinges no moves happen. Their truth is accepted as a precondition that makes testing possible. They’re true because we live them – e.g. grabbing a cup, not proving hands exist. They’re simply not candidates for truth/falsity. They set the stage for the testing of true and false.

2. Typical propositions can be doubted (this is key) – “Is it really raining?” If you doubt that you have hands you are not refining the truth; you’re opting out. The truth of hinges is a kind of immunity, not a verdict reached by evidence or reasons.

3. Hinges aren't true because they’re factual, but because they’re the frame facts rest on. The hinge “The Earth exists” isn’t a discovery, it’s the ground for discovering rain (OC 99 “riverbed”).

Sure, hinges look like typical propositions, i.e., they have a subject and predicate, but the job of a hinge is not the same. You don’t come to know its truth by investigation. It’s the rule that allows the game to move forward. Treating hinges like typical propositions is like trying to prove to someone that it's true after explaining the rule in chess that stipulates how bishops move. It’s not a move that we judge in that way, it’s the condition or foundation of the game, just like the pieces and the board. Hinges enable truth talk, they’re a precondition. Their truth is a necessity, just as the rules of chess are a necessity that enables chess games.

Propositions can be true or false, but hinges are true as a condition of being a hinge, i.e., it's their foundational role. Moreover, it’s our acting that cements them in place, not any fact that establishes their truth.

Why?

Does Wittgenstein demonstrate things like:
"Noesis is impossible."
"Truth is strictly a property of propositions,"
"Judgement is only proper to discursive reason, not to simple (reflexive) understanding,"
"Everything and anything is only intelligible and true or false as respects its context in a language or some belief system," ...
and the like?

I don't think he does at all. I think he dogmatically assumes these as a given and goes from there (maybe because he exposed himself to no other philosophy in his lifetime).But if noesis is possible his entire analysis is wrong. If this is not the case, can you show why?

It's sort of like Hume's "Problem of Induction," which just dogmatically presupposes Hume's deflationary account of causation and nominalism out the gate, and then goes from there (i.e. a sort of question begging that gets ignored because the presuppositions are common).

The role of the hinge seems to be in ossifying differences between peoples. The hinge doesn't appear to include a mechanism for recognizing its own fallibility. Is this a correct understanding?

Reply to RussellA

This is an interesting case, because God was often considered as the ontological ground of truth. Truth is most properly in the Divine Intellect, secondarily in things' adequacy to the Divine Idea/Logoi ("ontological truth," e.g., Scotus), and finally in the adequacy of the human mind to the "truth of/in things" (hence man is not the measure of truth in these theories, which the hinge proposition theory seems to reverse to some degree).

You are, rightly according to most readings of Wittgenstein, applying Wittgenstein's conclusions to all knowledge. However, as mentioned above re noesis, the existence of God—particularly of God as "truth itself"—would seem to undermine Wittgenstein's conclusions in a rather radical manner. That "I have hands" is a "hinge proposition" in Wittgenstein's sense of "hinge proposition" would itself rely on accepting certain hinge propositions (namely the denial of many Christian, Platonist, Islamic, etc. theories of truth and the fundamental beliefs that underpin them, since these would presume a different notion of the truth of "I have hands" and of reason, justification, and understanding themselves).

Yet belief in God certainly seems like it could qualify as a "hinge proposition," and yet it would seem that if it is embraced it refutes the notion of a "hinge proposition" as Wittgenstein sees it.

I suppose part of the issue here is a claim to universality by a theory that seems to deny the universality of truth. This parallels the classic problem of the post-modern contention that there are no universal/absolute truths, or that everything is mutable (claims taken to be universal, absolute, and immutable, some hand-waving about how their sense might shift notwithstanding). One would have to assert that the presuppositions of the theory are universal and beyond repute.

There is no doubt that Christians and other religions consider belief in God a hinge belief or foundational conviction. There is also no doubt that such language games exist. But just because there are language games that express these ideas doesn’t mean that all language games have equal footing. Some language games have a much better grounding, and we are constantly revising them.

However, the question of whether belief in God could be a hinge in the OC sense is an interesting question. Consider the following: “God exists” might ground certain practices like prayer, morality, and cosmology in the same way that “The Earth exists” grounds geology. Doubting that “God exists” would unravel the entire language game of many religions, just as hinges would unravel epistemology.

Also, for many, “Belief in God” isn’t up for debate within their lived belief system. It’s not a hypothesis that’s tested (for many) it’s a conviction that’s lived.

On the other side of the argument, “I have hands holds across contexts and language games. Atheists function without belief in God, but how would they function without the belief we have hands? Moreover, belief in God is doubted by many, and it’s debated in theology and philosophy. Wittgensteinian hinges resist doubt (OC 19 “incapable of doubting”). The belief that God exists invites doubt, even among those who believe.

I would say that in some cases, especially if someone had a direct experience of God, it could be a hinge for them. I think consciousness is a hinge, and if consciousness is fundamental, then it could be considered a hinge. Moreover, some might argue that consciousness/mind as fundamental might be God. I’m not sure, although I believe consciousness is fundamental.

There’s much more that could be asked and questioned, but this subject should be in another thread.

But are Wittgenstein's conclusions "tautologically" true for both the Christian and the atheist as well, or just for fellow Wittgensteinians?

From the perspective of the Patristics, or say, Thomism, Wittgenstein is simply deluded about the nature of truth, knowledge, and justification. If their disagreements come down to differences in hinge propositions (which they might), then how does the Wittgensteinian justify the claim that his conclusions are true not just for himself (and other Wittgensteinians) but for all human beings (and presumably, all rational agents)? Or does he not, and Wittgensteinian epistemology is simply "true for Wittgensteinians," just as you say "God exists" is true for theists, and not for atheists.

For, leaving aside the proper interpretation of Wittgenstein, to say that "God exists" and "God does not exist" can both be simultaneously "tautologically true" obviously requires a view of truth that is likely to differ fundamentally (i.e. in terms of bedrock understanding) from most historical views, under which claims that something is simultaneously both true and not-true, without qualification, is absurd and "senseless."

Reply to Sam26

Belief in God is not "epistemically neutral" however. It isn't something you can just choose to first "bracket out," if you are then to declare that your "bracketed consideration" applies equally for atheists and the faithful. For, the concept of divine illumination would contradict the idea that it is impossible to "know" without discursive justification. Yet this sort of simple knowing would challenge the notion that "I have a body" is the sort of thing that "cannot be known."

To assume that God can be "bracketed out," is to assume that God is irrelevant to the fundamentals of epistemology and the nature of truth.

This is a problem that I think is endemic to a lot of philosophy, from all eras, but maybe particularly contemporary analytic thought. The idea is something like:

"You can't say anything about metaphysics until you tackle how we can know anything. So we will bracket out metaphysical and physical concerns and just focus on epistemology."

But of course, it seems fairly obvious that metaphysical and physical considerations of "how we know" might indeed have crucial implications for how we want to construct our epistemology (e.g. as a "metaphysics of knowledge"). Moreover, as Przywara makes a good case for, this bracketing is never actually successful. One cannot actually set aside all considerations of being qua being (of parts and wholes, act and potency, etc.) and do any analysis at all. What ends up happening here is rather that metaphysical and physical assumptions are let in, and simply not acknowledged as such. For instance, "we shall bracket out the question of universals and proceed with a consideration of epistemology" amounts to "we shall assume nominalism is true, and develop our theories from there." But of course theories of universals and abstraction play a massive role in realist epistemologies, so this just becomes a sort of implicit question begging.

You can see the same sort of thing at work in the position that: "we shall begin with an analysis of language, since we must know our tools before doing any inquiry into epistemology or metaphysics."

This is not an entirely bad idea, but its implementation can be pernicious.

What do you see as the ‘rules’ of ‘I have hands’ such that they hold across language games? Would Wittgenstein accept that there is any sort of understanding that holds ACROSS language games? Wittgenstein would not have used ‘I have hands’ as an example of a hinge proposition if it were not possible to conceive of a language game in which such a phrase were not intelligible, or intelligible in a way that was incommensurable with Moore’s intent. Non-neurotypicals would be just one example of a population in which ‘I have hands’ might not be intelligible in Moore’s sense.

As far as belief in God, there are many kinds of faith in God, many kinds of conceptions of who or what God is, or where he/she/it is , or how they are. What you’re looking for as a hinge is the underlying metaphysics making intelligible both the kind of faith and the kinds of doubt that accompany it, rather than the proposition ‘God exists’.

Maybe try reading (and quoting) the entire sentence? For most Patristic thought, all men begin fundamentally deluded about truth, and we remain so for as long as we are focused on the mutable world and are not "climbing the ladder of virtue" (so for most of us, our entire lives lol). It would hardly be unique to Wittgenstein. It's like how Epictetus says "most free men are slaves (to the passions, etc.)"

Yes, based on many past theories of knowledge, Wittgenstein's assumptions are radically wrong. In exactly the same way, according to Wittgenstein's thought, Aristotle, St. Augustine, St. Thomas Aquinas, Avicenna, etc. were also deluded, "speaking nonsense," and writing a great deal where they should have remained silent.

Philosophers disagree. One cannot maintain that Wittgenstein is right and that many other's were not gravely mistaken or vice versa. They put forth contradictory theories of knowledge.

In the same way, if a contemporary physicalist is correct, Berkeley would be deluded.

But yes, I do think Wittgenstein was deluded about the nature of truth and knowledge. He never read much philosophy outside a very narrow niche and it blinded him to other options. I still respect his work and find it interesting. You seem to be falling into the trap of: assuming that if anyone disagrees they cannot possibly have understood (which brings up the question: "why do so many great thinkers passionately disagree with one another? Did they all fail to understand each other's work?"

Kant accuses virtually all prior thinkers (most of which he never read a page of) of being dogmatists for instance. Nietzsche's claims about Christian and Hindu ascetics are not flattering (the man studied neither tradition). Either their critiques are valid, or they aren't. It follows that if some people are right, others are very wrong (but maybe wrong in informative ways).

Edit: I don't mean to imply above that Kant is guilty of some grave error for not wading through thousands of pages of historical analysis. He had other things to do. Rather, philosophy has perhaps been collectively guilty of receiving the critique too dogmatically.

I think you're probably correct about Wittgenstein, but I have seen later sympathetic commentators try to link together all of humanity (or all embodied lifeforms in our universe) through a "shared form of life," that grounds important constants (generally as a way to defend Wittgenstein from charges of extreme relativism).

But then the "form of life" must be explained, since it is very vague in Wittgenstein's own work, and is doing a lot of lifting here. If this is done in terms of a broad paradigm of scientific realism, it does seem to get quite far from Wittgenstein's original thought, at least as far as I can tell.

Fair enough, putting God to one side.

One could argue that although the proposition "here is one hand" can be used across different language games, it could have different meanings. For example in the language games of the Direct and Indirect Realist.

For the Direct Realist (1), the proposition "here is one hand" is true, as they believe that the hand exists in the world. For the Indirect Realist (2), the proposition "here is one hand" may or may not be true, as they believe that the hand may or may not exist in the world.

The Indirect Realist is able to function successfully even though they believe that the hand they perceive may or may not exist in the world. For example, the Indirect Realist stops at a traffic light when they perceive the colour red, even though they believe that the colour red may or may not exist in the world.

For Wittgenstein, the hinge proposition "here is one hand" is independent of any world. As a hinge proposition, it is the foundation of the language within which it is a part, regardless of its truth, where truth is a correspondence between language and the world.

Notes
(1) Direct realism is the view that i) the external world exists independently of the mind (hence, realism) and ii) we perceive the external world directly (hence, direct). For the Direct Realist, we directly perceive hands that exist in the world.

(2) Indirect realism is the view that i) the external world exists independently of the mind (hence, realism) but ii) we perceive the external world indirectly, via sense data (hence, indirect). For the Indirect Realist, we also directly perceive hands, but the hands that we perceive may or may not exist in the world.

It isn’t independent of any world. On the contrary, it is the product of practical discursive engagement with others and with material circumstances in the actual world in which we live. That is why it is a form of life rather than a transcendental ideality. For Wittgenstein truth would be a correspondence between a hypothesis and an empirical event of the world , in which both hypothesis and world show themselves as already organized intelligibly on the basis of the same language game.

Yes, I think Wittgenstein would allow for basic understandings across language games. E.g., when we first believe things, it’s a broad swath of things. That I have hands underpins many of the language games of science, daily chat, games, etc

What you’re looking for as a hinge is the underlying metaphysics making intelligible both the kind of faith and the kinds of doubt that accompany it, rather than the proposition ‘God exists’.

Wittgenstein argued that the general is never to be understood as including within it the particular, that there is no one thing that members of a category have in common. Thus there can be no general language game including within it particular language games. There are only family resemblances among language games, and this family is not itself a game.


65. Here we come up against the great question that lies behind all these considerations.—For someone might object against me:
"You take the easy way out! You talk about all sorts of language­ games, but have nowhere said what the essence of a language-game, and hence of language, is: what is common to all these activities, and what makes them into language or parts of language. So you let yourself off the very part of the investigation that once gave you yourself most headache, the part about the general form of propositions and of language."
And this is true.—Instead of producing something common to all that we call language, I am saying that these phenomena have no one thing in common which makes us use the same word for all,— but that they are related to one another in many different ways. And it is because of this relationship, or these relationships, that we call them all "language". (P.I.)

Quoting Belief
Anglophone philosophers of mind generally use the term “belief” to refer to the attitude we have, roughly, whenever we take something to be the case or regard it as true.

and
Most contemporary philosophers characterize belief as a “propositional attitude”.


Few beliefs are openly the result of "judgement", if by that is meant explicit ratiocination. That some belief is indubitable does not imply that it is unstatable. If a belief is not true, it cannot be used to justify another belief.

That beliefs can be put into the form "I believe that p" where p is some proposition is pretty much constitutive of the philosophical conversation about belief.

Moyal-Sharrock presents a divergence from, rather than an elucidation of, On Certainty. Not unlike Kripkenstein.

From the perspective of the Patristics, or say, Thomism, Wittgenstein is simply deluded about the nature of truth, knowledge, and justification


@Sam26 suggested to me that "I don't want this thread to become an argument about the existence of God, and whether belief in God is a hinge."

However, it does seem that Pope Pius X did establish what Wittgenstein would call a hinge proposition about Thomism.

In the 1914 motu proprio Doctoris Angelici, Pope Pius X cautioned that the teachings of the Church cannot be understood without the basic philosophical underpinnings of Thomas's major theses:

The capital theses in the philosophy of St. Thomas are not to be placed in the category of opinions capable of being debated one way or another, but are to be considered as the foundations upon which the whole science of natural and divine things is based; if such principles are once removed or in any way impaired, it must necessarily follow that students of the sacred sciences will ultimately fail to perceive so much as the meaning of the words in which the dogmas of divine revelation are proposed by the magistracy of the Church. (Wikipedia - Thomism)

For, leaving aside the proper interpretation of Wittgenstein, to say that "God exists" and "God does not exist" can both be simultaneously "tautologically true" obviously requires a view of truth that is likely to differ fundamentally (i.e. in terms of bedrock understanding) from most historical views, under which claims that something is simultaneously both true and not-true, without qualification, is absurd and "senseless."


Yes, the Law of Non-Contradiction states that a proposition cannot be both true and false at the same time.

However, Wittgenstein's hinge propositions are neither true nor false.

There are many definition of "truth", but for me the most informative definition of truth is the correspondence between a proposition in language and a fact in the world.

Wittgenstein's hinge proposition is a foundation of the language of which it is a part, regardless of any correspondence between the hinge proposition and a fact in the world.

Therefore, the fact that the same hinge proposition may have different meanings in different language games does not break the LNC.

The hinge proposition

You are conflating two different types of propositions within the language game. There is the hinge proposition and there is the ordinary proposition.

You are right that the ordinary proposition is the product of practical discursive engagement with others, but the hinge proposition is a different thing altogether.

This is why Wittgenstein critiques Moore's "here is one hand". The whole point of Wittgenstein's hinge proposition is that is not the product of practical discursive engagement with others.

"Here is one hand" is the hinge proposition that is a foundation of the language within which it is a part.

"Here is one hand that is slightly larger than the other and is wearing a yellow glove" is the ordinary proposition that does engage with the world.

Reply to RussellA

The actual existence of God is sort of besides to point IMO. The point would be that people have often held conceptions of truth that would invalidate Wittgenstein's conclusions. Hence, Wittgenstein would need to prove that his presuppositions about truth must hold for everyone for his epistemic conclusions to be universal. Yet as far as I can recall he doesn't really take these on, he just assumes the core premises as obvious (see below).

The example from noesis is probably better than the examples from the relationship between God and truth, but I would imagine not everyone is particularly familiar with the concept.

There are many definition of "truth", but for me the most informative definition of truth is the correspondence between a proposition in language and a fact in the world.

Wouldn't this solution require the two assumptions that:

"Truth is primarily about (linguistic) propositions," and;
"Everything and anything is only intelligible and true or false as respects its context in a language or some belief system."?

But these are oft contested claims. For example, I would argue that it was true that the Moon orbited the Earth in 65 million BC. No languages existed then, yet this was still true. And further, I'd say that the truth of things (ontological truth) is the measure of the truth of the human intellect (the intellect's adequacy to being), rather than a human language being the measure of truth. I would imagine that I am in the vast majority today and historically in holding a position that is [I] something[/I] like this. Which doesn't mean that we're correct, only that the conception that truth is actually about language needs to be justified.

Second, I'd also defend a notion of sense knowledge. Other animals also possess sense knowledge. Yet sense knowledge is obviously not linguistic. So either it isn't really knowledge, or not all knowledge is linguistic. Likewise, one can know how to ride a bike," and yet this knowledge is neither propositional nor linguistic, and its truth is signified in successfully riding a bike (whereas linguistic utterances would be signs of truth in the intellect). If all truth and knowledge were linguistic those with severe aphasia would cease to know anything, yet they seem to still know many things.


Reply to Banno

Demonstration? Were is the "demonstration" that this text is in English? Where is the "demonstration" that this is a hand?


"This is a hand" or "we have bodies" are general assumptions that most have held throughout human history. Whereas:

"Noesis is impossible."
"Truth is strictly a property of propositions,"
"Judgement is only proper to discursive reason, not to simple (reflexive) understanding,"
"Everything and anything is only intelligible and true or false as respects its context in a language or some belief system," ...
and the like, are hotly contested philosophical issues. Indeed, Wittgenstein's presuppositions here are the fringe position in the broader history of philosophy. Yet, if noesis is possible for man, if the Thomists are right about the nature of truth, etc., then Wittgenstein's conclusions would not hold up.

Can he just presuppose these controversial claims as the "rules of doing epistemology?" If they are the "rules of epistemology," then why did most philosophers for most of history think Wittgenstein was wrong about noesis and the nature of our access to truth, or of truth itself?

The view that different things could be "true for different people" based on different hinges is far more akin to the popularity of "we do not have bodies" or "other minds do not exist." That is, it is a radical conclusion. But if one is going to draw a radical conclusion from controversial premises, will it do to simply claim that the premises are beyond demonstration (and thus presumably beyond repute)?

It reminds me a bit of the late-Hegelian position that "because the system is presuppositionless it is infallible."

Where do hinge propositions come from, and where do empirical propositions come from? If only empirical propositions are the product of discursive engagement with others, then how do we learn hinge propositions? From within the solitary imagination of the individual mind? Are we not brought up to see the world a certain way? And can we not be brought to look at the world in a different way?


92. However, we can ask: May someone have telling grounds for believing that the earth has only existed for a short time, say since his own birth? - Suppose he had always been told that, - would he have any good reason to doubt it? Men have believed that they could make the rain; why should not a king be brought up in the belief that the world began with him? And if Moore and this king were to meet and discuss, could Moore really prove his belief to be the right one? I do not say that Moore could not convert the king to his view, but it would be a conversion of a special kind; the king would be brought to look at the world in a different way.


If empirical propositions are formed through contact with the world and with others, what does it say about this world we are in contact with that it appears to us already interpreted through our hinge propositions? And what does it say about hinge propositions that we are brought up with them through cultural discursive transmission, and that they can be altered through practical discursive persuasion? Perhaps hinge and ordinary propositions are not two sharply distinguishable entities , but more or less fluid, more or less hardened aspects of the same practical discursive processes. Cannot hinge propositions be likened to Kuhnian scientific paradigms? How do we arrive at a new paradigm if not via contact with the world?


95. The propositions describing this world-picture might be part of a kind of mythology. And their role is like that of rules of a game; and the game can be learned purely practically, without learning any explicit rules.
96. It might be imagined that some propositions, of the form of empirical propositions, were hardened and functioned as channels for such empirical propositions as were not hardened but fluid; and that this relation altered with time, in that fluid propositions hardened, and hard ones became
fluid.
97. The mythology may change back into a state of flux, the river-bed of thoughts may shift. But I distinguish between the movement of the waters on the river-bed and the shift of the bed itself; though there is not a sharp division of the one from the other.
98. But if someone were to say "So logic too is an empirical science" he would be wrong. Yet this is right: the same proposition may get treated at one time as something to test by experience, at another as a rule of testing.

Conceptions of truth don't invalidate Wittgenstein's conclusion.

Wittgenstein proposed that "here is one hand" is a hinge proposition. A hinge proposition is a foundation of the language game within which it is a part. This makes sense, in that "god exists" is a hinge proposition of the Christian language game and "god doesn't exist" is a hinge proposition in the Atheist language game.

As I see it, for Wittgenstein, within a language are hinge propositions and ordinary propositions, and these are different things. IE, not every proposition within a language is a hinge proposition.

There are many definitions of truth. For example, see SEP article on Truth. However, I find the most informative definition to be when a proposition in language corresponds with a fact in the world then that proposition is true.

The hinge proposition "here is one hand" does not engage with the world, and is therefore neither true nor false, whereas the ordinary proposition "the cat sat on the mat playing with the mouse" does engage with the world, and can therefore be either true or false.

Wittgenstein's main conclusion is that "here is one hand" is a hinge proposition. A hinge proposition is a foundation of the language within which it is a part. It is not a demonstration of the existence of the world.

I agree that the hinge proposition "here is one hand" is neither a tautology, axiom or truism. It is the foundation of the language of which it a part, and allows the rest of the language to take place.

In a different language game, "this is a mountain" could be a hinge proposition allowing the rest of the language to take place. Discussion could then be had about mountaineers, snow falling on the mountain tops, the difficulties of skiers, which ski lodge to visit and the best flights for the skier to use from their home country. It would include the truth or falsity of propositions such as "Italy is the best country to visit for the serious skier". But it wouldn't include the truth or falsity of the proposition "this is a mountain".

Being neither true nor false, the hinge proposition cannot be invalidated by conceptions of truth or falsity.

But if noesis is possible his entire analysis is wrong.


Why?

Noesis seems to be the real content of consciousness. For example, the consciousness of the thought that here is one hand.

Wittgenstein's conclusion is that "here is one hand" is a hinge proposition within a language game.

It is the case, however, that Wittgenstein was of the general opinion that thinking and language were the same.

Notebooks 1914-16 - Now it is becoming clear why I thought that thinking and language were the same. For thinking is a kind of language. For a thought too is, of course, a logical picture of the proposition, and therefore it just is a kind of proposition.


Language would be of no use if the meaning of the words couldn't be thought about. Even though "here is one hand" is a hinge proposition, the meaning of the words can still be thought about.

The hinge proposition "here is one hand" doesn't negate the consciousness of thought that here is one hand.

I would agree with that. Sometimes an atheist finds god and sometimes a religious person loses their faith.

Both could come from a discursive engagement with the world. But as different people engage in different ways with the world, some propositions may be hardened into ordinary propositions and some hardened into hinge propositions

For example, it could be accident of birth, in that 93% of the population of Saudis Arabia is Muslim and 2% in South Africa. It could be innate within a person's character. It could be the teaching that they have had. It could be peer pressure. It could be particular life experiences.

Even though there may be a state of flux in a societies hinge proposition, it is still a useful concept and perhaps informative in explaining the undoubted gulf between Christian and atheist, liberal and conservative and Indirect and Direct Realist.

Reply to RussellA

The term "noesis" has been revived by modern thinkers in a number of ways that are quite different from the term's historical meaning, so perhaps that is a source of confusion here. I mean noesis as in "the direct, non-linguistic, non-discursive, reflexive grasp of truth by the intellect" (e.g. as detailed here https://theses.gla.ac.uk/2741/ for instance). I think it's fairly obvious that Wittgenstein doesn't think such a faculty exists, and that if it did, the entire theory of hinge proposition wouldn't be required. What makes things intelligible, on the view of most accounts featuring a faculty of noesis, is the intelligibility present in things, which is grasped by the mind, not things' place in a language game for instance. Likewise, truth in these theories if often framed in terms of identity instead of correspondence (e.g. Plotinus and the reception of Aristotle in Islam). That's a substantial difference that emerges from these different premises.

Just for one concrete example, Aristotle deals with a very similar set of questions in the Posterior Analytics. But he comes to a radically different conclusion about the nature of truth and human knowledge. I don't think either Wittgenstein or Aristotle's analysis is inconsistent or in error, at least not in particularly problematic ways for their main conclusions. Both were great logicians. However, their starting assumptions differ.

Reply to RussellA

Again, I agree that Wittgenstein's conclusions seem to be true given his starting assumptions (or a view similar to them, e.g. the modern analytic view of "correspondence truth" you begin from). You seem to agree with his starting assumptions. Fair enough. But are his starting assumptions (e.g. that truth is primarily about language and statements, that "truth only takes place within language games") unimpeachable?

I don't think they are, and I don't think his conclusions hold if you don't grant him this and other premises. But my point is that people with different hinge propositions will clearly not grant Wittgenstein the premises he presupposes in his analysis, as evidenced by the fact that they are historically unpopular positions (and really, relatively recent developments which never supplanted the dominance of a view that holds to a sort of ontological truth in "physical things").

So, I don't see how the fact that "Wittgenstein's conclusions hold up if we make similar assumptions to him," says much on this particular issue. I'd agree with that. But for the conclusions to apply to epistemology tout court, they need to either rely on uncontroversial premises (they don't) or the premises need to be demonstrated (they aren't).

I'll just refer back to the quote I shared earlier, from a quite influential thinker/authority from an earlier epoch:

...neither are all things unutterable nor all utterable; neither all unknowable nor all knowable. But the knowable belongs to one order, and the utterable to another; just as it is one thing to speak and another thing to know.

I don't understand the relevance of the example. That certain text is written in a given language isn't the sort of thing that would be a hinge proposition, nor would it be an assumption that is relevant to Wittgenstein's conclusions (nor would it be controversial).

"Noesis is impossible."
"Truth is strictly a property of propositions,"
"Judgement is only proper to discursive reason, not to simple (reflexive) understanding,"
"Everything and anything is only intelligible and true or false as respects its context in a language or some belief system," ... etc.

Are as obvious as the fact that this post is written in English or that you have hands? What's the idea, that somehow these presuppositions are necessary for language? But that seems obviously false, because they weren't positions held through most of the history of philosophy.

Well, yes it is. That this sentence is in English is something you cannot doubt, in the act of reading it. It's a neat example of
OC:341. That is to say, the questions that we raise and our doubts depend on the fact that some propositions are exempt from doubt, are as it were like hinges on which those turn.

"This is in English" is exempted from doubt by our reading it. To doubt that it is a statement of English one would have to supose that it does not say that it is in English.

You do not get a choice as to whether to see it as in English or not.

Now to be sure, there might be a language in which the sentence "This is in English" meant what in English we mean by "The cat is on the mat". If this were so, and you were familiar with that language, you might justifiably wonder whether the marks "This is in English" ment that the sentence was in English or that the cat was on the mat. But that would be to doubt what you were reading. If you take the sentence as saying that it is in English, then you cannot also doubt that it is in English. And if you take it as saying that the cat is on the mat, then you will cast into doubt the whole of this post, along with the rest of the forums and a large part of what you know. If that is what you want to do, then there is not much point in continuing this discussion.

Hence,

343. But it isn't that the situation is like this: We just can't investigate everything, and for that reason we are forced to rest content with assumption. If I want the door to turn, the hinges must stay put.


Notice that "we are forced to rest content with assumption"; we are not offered a choice here, such as that there is only one line through a given point that is parallel to another line, or that If A is true then ~A must be false. If we are to deal in euclidean Geometry, we are forced to accept the Parallel Postulate; and if we would deal in classical logic, we are forced to assume the excluded middle.

The Parallel Postulate is constitutive of Euclidean Geometry, and Excluded Middle is constitutive of classical logic.

A proposition is not a hinge in any absolute sense, but just in virtue of the role it takes on in a language game. So the same proposition may be a hinge in one game but not in another.

Reply to frank No need to use a Zulu when we can use Wittgenstein himself. He took "Folk have never been to the Moon" as a hinge, it seems...

106. Suppose some adult had told a child that he had been on the moon. The child tells me the story, and I say it was only a joke, the man hadn't been on the moon; no one has ever been on the moon; the moon is a long way off and it is impossible to climb up there or fly there. - If now the child insists, saying perhaps there is a way of getting there which I don't know, etc. what reply could I make to him? What reply could I make to the adults of a tribe who believe that people sometimes go to the moon (perhaps that is how they interpret their dreams), and who indeed grant that there are no ordinary means of climbing up to it or flying there? - But a child will not ordinarily stick to such a belief and will soon be convinced by what we tell him seriously.
107. Isn't this altogether like the way one can instruct a child to believe in a God, or that none exists, and it will accordingly be able to produce apparently telling grounds for the one or the other?
108. "But is there then no objective truth? Isn't it true, or false, that someone has been on the moon?" If we are thinking within our system, then it is certain that no one has ever been on the moon. Not merely is nothing of the sort ever seriously reported to us by reasonable people, but our whole system of physics forbids us to believe it. For this demands answers to the questions "How did he overcome the force of gravity?" "How could he live without an atmosphere?" and a thousand others which could not be answered. But suppose that instead of all these answers we met the reply: "We don't know how one gets to the moon, but those who get there know at once that they are there; and even you can't explain everything." We should feel ourselves intellectually very distant from someone who said this.

but then...
97. The mythology may change back into a state of flux, the river-bed of thoughts may shift. But I distinguish between the movement of the waters on the river-bed and the shift of the bed itself; though there is not a sharp division of the one from the other.


Again, being a hinge proposition is a role taken on within a language game, rather than a property of certain propositions in all cases.

This is part of how hinge propositions differ from supposed necessary or a priori propositions.

This by way of agreeing that hinges are too bound up in living as a human to doubt them.

But what language an archeological text is written in is an empirical question, no? It's only obvious if you know the language in question, otherwise it's something you can discover. I know Latin well enough that I can identify a Latin text, maybe, but it is by no means obvious. I might need a book, Italian can be pretty close. "This is in Latin" is definitely something I might be mistaken about.

Anyhow, I still don't see the relevance of the example. Are you claiming that Wittgenstein's epistemic presuppositions are "just seen" and essentially unimpeachable, beyond analysis, and beyond repute?

If this is so, why did most philosophers for most of history not accept such presuppositions? And if if Wittgenstein's presuppositions only appear relatively recently, how are the conclusions he draws for them "absolute" such that they apply to all epistemology and not just people making the same assumptions?

To be honest, "I am right about these contentious premises because it is impossible to think otherwise because it is the very prerequisite for thinking/language" strikes me as very much the same sort of thing the empiricists lampooned the rationalists for when they claimed thought was impossible to challenge their conclusions because it is impossible to think without their "innate ideas."

Nothing of the sort. I am just pointing out that Wittgenstein starts from assumptions about the nature of truth and knowledge that were common to his niche, but which are not common to philosophy more broadly. His conclusions follow from these assumptions.

If one starts with different assumptions (which presumably might stem from different hinge propositions), then it doesn't seem like Wittgenstein's conclusions will follow. Yet presumably his conclusions are supposed to be universal, covering the whole of epistemology.

For instance, I don't think one has the demonstrate that a faculty of noesis exists in order to point out that presupposing as a given that it doesn't seems unwarranted. So too for the assumptions about the relationship between truth/intelligibility and language.

If one is troubled by Wittgenstein's conclusions the most obvious next question is: "are his premises true? What reasons does he give for us to accept them?"

They certainly don't seem like premises that "must be accepted as the very basis of using language."

The opening of TLP makes several clear. The ones that jumped to mind as problematic are:


"Noesis (a non-discursive, non-linguistic, reflexive grasp of truth) is impossible."
"Truth is strictly a property of propositions,"
"Judgement is only proper to discursive reason, not to simple (reflexive) understanding,"
"Everything and anything is only intelligible and true or false as respects its context in a language or some belief system," ... etc.
"It is not the case that truth is first in things, then in the senses, then in the intellect, and that human language is a sign/symptom of truth, but rather truth is a property of language games."

The term "noesis" has been revived by modern thinkers in a number of ways that are quite different from the term's historical meaning, so perhaps that is a source of confusion here..................................I think it's fairly obvious that Wittgenstein doesn't think such a faculty exists


Not only Wittgenstein, but many modern philosophers don't accept the concept of Transcendental Aprioris, of which noesis is a part.

As described by MR Burgess, noesis is a part of Transcendental Apriorism, a Rationalist doctrine originated by Plato. It proposes that a solitary thinker using pure reason can unlock the deepest mysteries of external reality. This is an epistemological problem, the notion that the pure human intellect, purged of sensory contamination, can transcend the limits of experience to reach a Platonic understanding of reality.

Plato called the highest form of knowing "noesis". In modern terms, insight. Noesis is the highest form of human thought, and allows the mind direct apprehension of universal truths. Noesis is in opposition to dianoia, discursive thinking and analytical explanations. For example, explaining how a car engine works.

Many modern philosophers from Kant onwards, including the Logical Positivists and AJ Ayer, reject Transcendental Apriorism. However, Burgess argues that such rejection has been too cursory, and the theory should begin to be taken more seriously.

Defenders of Transcendental Apriorism will have a difficult task in justifying how a solitary thinker only having access to their sensations and just using pure reason will be able to unlock the mysteries of the reality of an external world. As WH Walsh wrote in Reason and Experience "There seems to be little difficulty in showing that metaphysics in this sense is an impossible undertaking".

I think the point of the TLP is to show that when we talk about "understanding reality" in some rarified sense, we're doing something with language that it's not designed for. What sorts of things go on beyond the realm of language? There's nothing to say about that.

In other words, Witt wasn't trying to say that consciousness excludes anything beyond the word circus. He was just pointing out that going on and on about things that are beyond language is foolish.

Sure. My point is not about archeology, but about the sentence you are reading now. To doubt that this sentence is in English is to doubt that you understand what this sentence says.

Point being that in order to engage with the text one must first accept certain propositions, even if not explicitly. That this post is in English being one such proposition. Such propositions are good candidates for hinge propositions.

That might not be a prerequisite for thinking but it is probably a prerequisite for replying coherently to this post - for continuing this discussion.

I think that you are partly right and partly wrong.

Partly wrong in that a Wittgenstein sentence, such as "snow is white", does correspond with the reality of the world. The Tractatus is basically setting out a correspondence theory.

There are two aspects to a Wittgenstein sentence. Simple sentences such as "snow is white" are true when they correspond with facts in the world. Complex sentences, such as "snow is white and trees are green" are true by virtue of the Truth Table.

Partly right in that Wittgenstein is vague in justifying whether a Wittgenstein proposition, such as "Jack believes that Mars is green", do correspond with the reality of the world.

When you talk about consciousness, it depends whether you mean from the point of view of the Rationalist, which includes Transcendental Apriorism, or from the point of view of the Empiricist.

Wittgenstein did not agree with the Rationalists, who believe that concepts and knowledge can come from a solitary thinker using pure reason isolated from contaminated empirical experiences.

I agree, more or less.

It seems to me that there are three main theories of perception: Idealism, Direct Realism and Indirect Realism

In the Tractatus, truth is basically a correspondence between language and the world. "Snow is white" is true if snow is white.

In Philosophical Investigations, truth is basically a correspondence between language and its own conditions for being true. "Theft is wrong" is true if theft is wrong.

I agree that Wittgenstein includes references in Tractatus to a "gramophone record" and in Philosophical Investigations to "bring me a slab". These objects exist in our world, which makes one assume his approach is that of Realism.

However, this is not necessarily the case, in that although gramophone records and slabs exist in a world, the question is, where does this world exist. This is something that Wittgenstein is very vague about.

For the Idealist, the world exists in the mind. For the Direct Realist we directly perceive the world and for the Indirect Realist we directly perceive representations of the world.

Wittgenstein in general should not be read from the viewpoints of either Idealism or Realism

Thinking of the "world" as either mind-dependent or mind-independent may not be how to approach Wittgenstein.

Wittgenstein's Hinges Reimagined

Abstract

Ludwig Wittgenstein’s (1889-1951) final notes were published posthumously as On Certainty (1969). In these notes, he introduced the concept of hinge propositions (OC 341) as a response to G.E. Moore’s arguments (“Proof of an External World,” 1939) against the radical skeptic. Wittgenstein’s hinges function as indubitable certainties outside the domain of epistemological justification. They differ from traditional propositions by enabling traditional truth operations to function. This paper reimagines hinges as foundational convictions, namely, as arational certainties that act as a foundational platform that grounds our epistemological language and systems of proof.

Building on this foundation, the paper extends Wittgenstein’s hinges to Kurt Godel’s incompleteness theorems (1931), which demonstrate that any consistent formal system of arithmetic will necessarily contain unprovable statements. Godel’s mathematical discovery parallels Wittgenstein’s hinge insights, revealing the need for system-enabling certainties that ground both frameworks. The problem of infinite regression further illustrates the need for foundational convictions.

This bridges the gap between mathematical formalism and epistemological foundationalism and challenges the notion that any comprehensive proof is possible in either domain. The paper offers a novel approach to understanding the limits and foundations of human knowledge.

I can see how you might think they're contradictory, but I'm making a subtle distinction about truth, which I believe Wittgenstein is also making. Hinges aren’t true in the same way that ordinary propositions are, i.e., they're beyond the truth-testing game. Their truth is their unshakeable role in our practices. Wittgenstein points out, “It belongs to the logic of our scientific investigations that certain things are indeed not doubted” (On Certainty 342). They’re not conclusions; they’re the ground.

The truth of traditional propositions is tied to evidence or falsifiability. “It’s raining” is true if I look out and see rain; it’s false if I don’t. Hinges can't be meaningfully doubted without collapsing the system. Doubting “The earth exists” isn’t false, it’s nonsensical, as no test could apply outside the framework of everyday epistemological language. Doubt is essential to how we use traditional propositions. “The keys are on the table” invites checking; it’s true or false based on what I find. However, again, the truth of a hinge, which is like a foundational conviction, is indubitable (impossible to doubt, unquestionable).

Hinges are indubitable not because they’re proven beyond doubt but because they’re the foundation of doubting, outside the game of justification. Ordinary propositions play inside that game, subject to the rules hinges silently uphold. Wittgenstein’s move is to say: what Moore calls indubitable truths aren’t truths in the propositional sense. they’re the very backdrop that lets propositional truths get their life.

Think of a conviction, one could hold that it's true without appealing to justification, it's bedrock to a system of beliefs that are justified and true. These truths are essential to how I act in the world, but their function is much different.

If I repeat myself, it's for effect.

It is not that "hinges aren’t true in the same way that ordinary propositions are", but rather that hinge propositions are not truth-apt at all.

It is not that "their truth is their unshakeable role in our practices", as hinge propositions have no truth.

It is true that in Philosophical Investigations there is a role for hinge propositions in the language game, but here the word "true" refers to the role that the hinge proposition is playing, not to the hinge proposition itself.

The word true shouldn't be applied to a hinge proposition. For example, as in "hinges aren't true in the same way" and "their truth".

Sam26 March 31, 2025 at 17:03 #979877
There is support, but there is also seeing where his notes are leading us. I've said this before, but let me repeat it. There are two language games of truth in OC. One is the language game of traditional propositions, which can be true or false and require justification. The other language game of truth is one of foundational convictions. The latter convictions are accepted as true and cannot be sensibly doubted. If they can't be doubted, it means they can't be false. Whereas traditional propositions have true/false built into their meaning. These convictions are lived truths built into our actions. They reflect subjective certainties that we all have. If they could be doubted and thus false, knowledge would collapse

The two language games I'm referring to are seen in one use of 'I know.." as an epistemological use, the other use as an expression of a conviction. Something I believe to be an indubitable truth, which doesn't have a justification like normal propositions. There is no justification; it's a lived conviction shown in our actions.

It's ok if people disagree that's just the nature of philosophy.

Let me offer two ways of thinking about this distinction between ‘I know’ as epistemological and ‘I know’ as hinge conviction, and you tell me which one you prefer. According to the first way, in both the epistemological and the hinge ‘I know’, truth is a correspondence between what I believe to be the case and what is actually the case. But the hinge ‘I know’ doesn’t have a justification or proof for its conviction that the way things really are corresponds to the way I believe them to be.

In the second way of thinking, only the epistemological ‘I know’ represents my conviction (justifiable or not) that what I believe to be the case corresponds to what is actually the case. The hinge ‘ I know’ is not a conviction that what I believe corresponds with the way things actually are. It functions prior to correspondence, and the split between hypothesis and experience. Both what makes hypothesis and any possible experience that could
validate or falsify it intelligible are already framed by the hinge conviction.

There are different types of doubts too i.e. rational doubts based on reasoning, and psychological doubts based on feelings, emotions and beliefs.

When a doubter is psychologically motivated by such as the groundless beliefs or Machiavellianism & Hyper-Competitiveness syndrome, he will not notice or understand the rational side of arguments or knowledge on the facts even with the clear evidence and rational explanations on the matter.

There would be no way to stop him from the doubting unless the causes for the psychological motivations for the doubts are resolved.

How Are Hinges True?

Hinge propositions, like the earth has existed for more than ten minutes or "I have two hands” —aren’t true in the way we typically think of propositions being true (i.e., through evidence, justification, or correspondence to reality). Wittgenstein’s point in OC is that hinges are the bedrock of our epistemic practices—they’re what we don’t doubt to even start asking questions or justifying anything else (OC 341-343). So, their truth isn’t about being proven; it’s about their role in our forms of life.

Hinges are true in a practical, functional sense—they’re the scaffolding we rely on to play our language games. In OC 94, Wittgenstein says, “I do not explicitly learn the propositions that stand fast for me. I can discover them subsequently like the axis around which a body rotates.” They’re true because they’re embedded in how we act and think, not because we’ve epistemologically validated them. For example,things don’t vanish randomly (OC 342) isn’t something we test - it’s what lets us test other things.

Their truth comes from being immune to doubt within our system. In OC 115, he writes, “If you tried to doubt everything, you would not get as far as doubting anything. The game of doubting itself presupposes certainty.” Hinges are true in the sense that they’re the ground we stand on—doubting them unravels the whole game, like pulling the tablecloth out from under a dinner party.

Traditional truth often means a proposition matches reality (e.g., “snow is white” is true if snow is, in fact, white). Hinges don’t work that way. “The earth exists” (OC 99) isn’t true because we checked; it’s true because our entire way of living—building houses, farming, launching rockets - assumes it. Their truth is more like a lived certainty, not a verified fact. This is very similar to the rules of chess that allow the game to be played.

Justification, as an epistemological practice, stops at hinges. Wittgenstein says in OC 204, “Giving grounds, however, justifying the evidence, comes to an end;—but the end is not certain propositions’ striking us immediately as true, i.e., it is not a kind of seeing on our part; it is our acting, which lies at the bottom of the language-game.” So, if hinges aren’t epistemologically justified, what kind of truth do they have?

If justification is epistemological, hinges live in a pre-epistemic space. Their truth is a kind of certainty that’s more basic—almost instinctual or animal, as Wittgenstein hints in OC 475: “I want to regard man here as an animal; as a primitive being to which one grants instinct but not ratiocination.” The truth of “I have hands” (OC 153) isn’t argued for—it’s a certainty I live with, like breathing. It’s true because it’s part of the scaffolding of my existence, not because I epistemologically proved or justified it.

How can you have a conviction (OC 102) that's not an expression of something you believe is true? Hinges are true is a matter of pragmatics or a way of acting, it's a different language game. Again, like the rules of chess. Someone might ask you "Is it true that bishops move diagonally?" and you reply, "Yes," but does this mean that it's true in an epistemological sense? No,

OC isn't a finished work, so we don't know which passages would have been left in or eliminated.

"It is raining" is true1 IFF it is raining

You say that hinge propositions are true2, where true1 and true2 are different.

But how have true1 and true2 been defined? A proposition that corresponds with a fact is true1. A proposition that is exempt from doubt is true2 (OC 341)

The definition of true1 is well established, and there are many references in the literature. However, the definition of true2 does not seem to be established at all, and I haven't found any references to it in the literature.

It seems that true2 is your personal definition. There is nothing wrong with inventing definitions, in fact I invented the definition "peffel". However, no-one other than me uses it.

ii) That Paris is in France is exempt from doubt means that we are not even allowed to doubt at


One way of understanding ‘exempt from doubt’ is the way I suggested here:

Quoting Joshs
In the second way of thinking, only the epistemological ‘I know’ represents my conviction (justifiable or not) that what I believe to be the case corresponds to what is actually the case. The hinge ‘ I know’ is not a conviction that what I believe corresponds with the way things actually are. It functions prior to correspondence, and the split between hypothesis and experience. Both what makes hypothesis and any possible experience that could validate or falsify it intelligible are already framed by the hinge conviction.

How would you replace "exempt" by "impossible" in the above sentence?


You don't. It was a suggestion for W if he used the word "impossible" rather than "exempt", it would have been clearer in the point.

"Exempt" is normally used for the situation where an object is free from liability, duty or restriction. Hence it seems not a proper word to use for doubt.

My idea is that you can doubt on anything and everything if you choose to do so. Even the fact "Paris in France." could be doubted under the simple syllogism.

Names of cities could be changed into some other name through time.
Paris is a name of the city.
Paris could be changed into some other name through time..

which implies Paris might not be in France sometime in the future. (weak doubt for the possibility in the future = still a doubt).

Banno April 01, 2025 at 22:02 #980103
The use of "true" with the lowest common denominator is that given by a T-sentence.

Being a hinge proposition is a role in a language game. Doubting is a language game or a part of a language game. Being a hinge proposition is being unavailable for doubt in the language games being played. Language games are not discrete - does that need saying?

Some hinge propositions are of the form "...counts as...", and as such their role is in setting up the language game. "The piece that only moves diagonally counts as a bishop"; "This counts as a hand"; "'P' counts as true if and only if P". These sentences set up being a bishop in Chess, being a hand in ontology, and being a true sentence in epistemology.

Are all hinges of this form? I'm not sure. You decide. Have a look at propositions you think are hinges and see if they fit, and if they do not, ask if it is because they are not analysable as "...counts as..." or becasue they are not hinges.

Notice that one can form a T-sentence for any proposition, hinge or otherwise. There is no special nature of truth peculiar to hinge propositions. Again, being a hinge proposition is something we do with a proposition when we use it to set up a language game.

This is how truth and hinge propositions work.

In a language game are ordinary propositions such as "it is raining" and hinge propositions such as "here is one hand".

:up: Continuing:

For example, in a language game, "here is one hand and the hand is holding a mug of coffee", "here is one hand" is the hinge proposition and "the hand is holding a mug of coffee" is the ordinary (non-hinge) proposition.

Being an ordinary proposition, "the hand is holding a mug of coffee " can be true or false, depending on whether or not it corresponds with what is actually the case in the world.

But the truth-aptness of this ordinary proposition is only intelligible if the language game has been founded on a hinge proposition.

Because, if a language game was not founded on a hinge proposition, and there were no hinge propositions, then the meaning of each expression would depend on its context within the language game.

IE, the meaning of "the hand" would depend on its context "the hand is holding a mug of coffee", and the meaning of "holding a mug of coffee" would depend on its context "the hand is holding a mug of coffee". Although this language game might be perfectly coherent, it would be ultimately be nonsensical.

For a language game to make sense, within the language game there must be something extra-linguistic that founds the language game within the world, and these things are the hinge propositions.

Hinge propositions are extra-linguistic, even they they are part of the language game.

The T-sentence assumes a proposition’s truth is about whether the content matches reality, but hinges aren’t evaluated like that. In OC 205, Wittgenstein says the ground (hinges) isn’t true or false—it’s just the ground. “The earth has existed for a long time” (OC 85) isn’t true because we’ve checked it against reality—it’s true because it’s a hinge, a certainty we don’t doubt. The T-sentence (“‘The earth has existed for a long time’ is true if and only if the earth has existed for a long time”) doesn’t capture this. It’s a formal equivalence, but it misses the lived role of the hinge as a conviction we act on. Hinges don't play this formal game.

The truth for hinges is pragmatic, not formal. Wittgenstein ties truth to our forms of life, not to logical definitions. In OC 241, he says truth and falsity depend on our shared language, our forms of life, not on a formal standard like the T-sentence. Thetruth of “I have hands” isn’t in a T-sentence; it’s how I live: I use my hands every day, and I don’t doubt them. In OC 204, he says our acting is what matters. The T-sentence is too abstract, it doesn’t get at the pragmatic, action-based nature of hinges’ truth.

The language game of hinges is different. The game of truth for empirical propositions (“It’s raining,” check the window) is different from the game of truth for hinges. In OC 243, he says, “One says ‘I know’ when one is ready to give compelling ground - but with hinges, there is no such possibility.” Hinges don’t play the game of justification or demonstration. They’re certainties we live by. The T-sentence assumes a single game of truth, but Wittgenstein’s approach is more pluralistic. The truth of hinges is a different game—one of lived certainty, not formal equivalence.

Not all hinges fit the "counts as" mold (if that's your point @Banno): "The Earth has existed for more than 10 minutes" or "Objects don't vanish randomly" are background certainties (convictions), not rule-setting propositions. I think Wittgenstein's pragmatism captures the truth of these certainties and fits our life forms much better.

We treat hinges as true for practical reasons. And the fact that they're not doubted demonstrates they don't play the true/false game. We accept them as true, period.







sime April 02, 2025 at 13:36 #980203
I suspect that hinges refer to what Frege called "taking as true".

For example, I often "take it as true" that my colour judgements are synonymous with the optical colours, due to learning the colors by ostensive definition; in spite of the fact that the definition of the optical colours makes no mention of my color judgements.

If this is the case, then hinges represent an extension of thought from Wittgenstein's earlier remarks in relation to private language, and possible represent a footnote to, or even an attack on, Frege's anti-psychologism that sought to clearly delineate truth from "taking as true".

There are many different definitions of "truth" (SEP - Truth)

Wittgenstein did not consider the hinge proposition as being true.

OC 204 Giving grounds, however, justifying the evidence, comes to an end; - but the end is not certain propositions' striking us immediately as true, i.e. it is not a kind of seeing on our part; it is our acting, which lies at the bottom of the language-game.

Reply to RussellA Wittgenstein is not referring to traditional theories of truth - like the correspondence (matches reality) or coherence theories (fits within a system of beliefs). These may work for empirical propositions like "It is raining." Hinges are about lived truths, i.e., how we act without doubting. If you're stuck with traditional ideas, then you'll never see this. Wittgenstein is thinking outside the box of traditional ideas of epistemology. These truths are outside epistemology, they give life to epistemology, which means they give life to our ideas of justification and truth. Without these truths/convictions, there would be no talk of propositional truth. So, it's very pragmatic, and they lie at the very bottom of our forms of life. If you doubt what's bedrock, everything collapses. If you're looking for a definition, especially a traditional one, you won't find one.

They're a pragmatic lived foundational/bedrock truths, but without the possibility of being false, i.e., doubted. Remember, if you doubt the truth or falsity of a traditional proposition, you're challenging one of the true/false paradigms. Hinges are beliefs accepted without question. If you doubt them, nothing follows, even the questions fall apart.

Maybe I am misunderstanding the point here. It seems to me that we misunderstand and misuse words all the time. Someone might confuse an uncommon word like "dearth" with "surfeit," when it means the opposite. They might even use the word in this way (hell, I've done this lol). Yet eventually we might come to doubt the meaning of the part if it is behaving strangely (e.g. if the context implies an alternative meaning).

But to Reply to frank's point, which perhaps you will disagree with, it hardly seem that this should mean exiting the "language game" unless "language game" is rather carefully defined (and I fear this would have to be done in an ad hoc manner).

When Descartes starts doubting away in the Meditations, he doesn't stop writing in French. We live in the aftermath of massive efforts to standardize dialects and spelling, where universal compulsory education has ironed out a lot of divergence, but from what I understand it was quite possible to have doubts about understanding text or speech in some close dialect, to be unsure if one had grasped the meaning quite right, particularly if one knew the broader language (as opposed to dialect) as a second language. Italy for instance is rather famous for this and there are some jokes about it in old literature.

You can still sort of get this experience in Scotland or Jamaica, or even moreso in pidgin dialects. Or, for a less expensive experience, go read the BBC Pidgin page. You will understand some, not understand other parts, and be unsure about others: https://www.bbc.com/pidgin

Donald Trump tok say im "no dey joke" wen e say im wan do third term as US president.

Di US Constitution say "no body... go dey elected more dan twice", but some Trump supporters don suggest say ways fit dey around am.

Wen dem ask am for one interview wit NBC about di possibility of seeking a third term for di White House, Trump say "methods dey on how to run am".

"I no dey joke... plenty pipo want make I do am," e add. "But, I just dey tell dem say, we still get long way to go, you know, e still dey very early for di administration."

Dem ask Trump, wey go be 82 at di end of im second term, e go wan continue dey serve for "di toughest job for di kontri".


Written pidgin is probably not the best example though. I feel like it's pretty intelligible to English-speakers. Spoken is an entirely different story, and very much in a grey zone (for me at least).

I would think not, although it would depend on how we define doubt. I do think they can confused and usure, have misapprehensions, or "second guess themselves" though. Doubt, to me, would require some distinction between reality and appearances, but also the knowledge of beliefs as true or false, making it properly intellectual.

However, a sort of sensuous misapprehension/confusion seems analogous to proper, intellectual doubt. And there the same seems true. You cannot experience this towards everything at once. Some background of sensuous intelligibility would be needed, else it would be sheer confusion, something like the results of a concussion or stroke.

Well, no, T-sentences are not just a reinvention of correspondence. The sentence on the left might not have any correspondence at all, and yet the T-sentence would be true:
"The goat is a democracy" is true IFF the goat is a democracy

Usually a T- sentence is treated extensionally. That's probably enough for here. There are however, intensional treatments that use them. in Montague semantics this is fairly straight forward, but in constructivist treatment it would be more interesting - something like "S" is true ??p(p is a proof of S), perhaps

It's what we do.

Notice the difference in direction, the change from word-to-world to world-to-word. The world is changes so that "hand" refers to this, so that bishops only move diagonally, and so that "P" is true only if P.

Notice also that what we say is amongst the things that we do. Saying, and hence propositional knowledge, is a sub-class of doing, and hence know-that is a sub class of (parasitic on...) know-how.

Notice also that what we do can be put into a propositional form - usually first-order. Hinges can be put into propositional form, and also have a realisation in what we do. Hence, again PI§201 - there is both a way of saying that this is a hand and a way of doing with hands.

Quoting Sam26
The language game of hinges is different.

There is no "language game of hinges". Being a hinge is a role in a language game, it's what we do in order to be able to "play".

Quoting Sam26
"The Earth has existed for more than 10 minutes"

This is a hinge becasue we assume it in order to continue on with the game - to deal with the Earth in our usual way, "the Earth" counts as something that has been around for a very long time. So the car you recall parking in the garage will be found in the garage. "Objects don't vanish randomly" might render as "to count as an object is to have relative permanency" - and the role here is to rule out some things as objects...

The language game that includes the sentence "Sherlock Holmes lives at 221B Baker Street" is embedded in a world of literature rather than a world outside literature.

It seems that Wittgenstein agrees that there is a world but never specifies exactly where this world exists.

My understanding is that in a sentence such as "here is one hand and in the hand is a mug and in the mug is an elephant", not only is every part a hinge proposition but also every part can form a T-sentence.

Each part, i) "Here is one hand", ii) "in the hand is a mug" and iii) "in the mug is an elephant" has to be a hinge proposition in order to allow the rest of the language game to take place.

That a language game is embedded in the world means that there is a correspondence between the language game and the world. If the language game was not embedded in the world, then there could be no correspondence between the language game and the world.

That there is a correspondence means that the T-sentence can be formed from each part, i) "here is one hand" is true IFF here is one hand. ii) "in the hand is a mug" is true IFF in the hand is a mug, iii) "in the mug is an elephant" is true IFF in the mug is an elephant.

In a T-sentence, what does "true" mean? It seems to mean that in the event that something is the case in the world, something does obtain in the world or something is a fact in the world, then that fact can be described by language.

You point out that in ordinary language we do doubt the meaning of some words all the time, so where in ordinary language are those propositions that are exempt from doubt?

In the Meditations, Descartes was discarding all beliefs that were not absolutely certain. He was not discarding all words about which he was not absolutely certain. I can doubt ever getting a good meal in Paris without doubting the meaning of the words "I can doubt ever getting a good meal in Paris". I can use words whose meaning I am certain about to express ideas about which I am not certain.

We may doubt the meaning of some words all the time but we never doubt the meaning of all the words all the time.

As an example consider the sentence "it seems to me that we misunderstand and misuse words all the time."

If I doubted the meaning of every expression within the sentence, the sentence as a whole would be meaningless to me, making it impossible for me to respond to it. But I am responding to it, meaning that in practice I am certain as to the meaning of the words used.

If I doubted the meaning of every expression within the sentence, language as a means of communication would be impossible.

For example, in the sentence "Inaonekana kwangu kwamba hatuelewi na kutumia vibaya maneno kila wakati." there is not a single expression whose meaning is exempt from doubt in my mind

But we know that language does work in enabling communication, therefore there must be some expressions within our language exempt from doubt, as Wittgenstein wrote.

It may be the case that in a sentence there are words whose meaning I am not certain about,
but in that situation I can refer to a dictionary, which may then remove any uncertainty as to its meaning.

If I find the meaning of a word uncertain, I would reach for the Dictionary, not stop writing.

OC 205 seems to indicate that the true/false idea shouldn't be used with hinges, but again, he's talking about traditional hinges. Moreover, we can't forget OC 206, where Wittgenstein points out that if someone asked, "but is that true" (referring to hinges), we might respond "yes," Which gets to my point that we do treat hinges as true in a practical sense, i.e., a lived certainty. In other words, I act in a way that shows their truth. The act of opening a door shows my certainty that there is a door to be opened, and it shows my certainty that I have hands. This practical certainty is a very practical truth.

Wittgenstein's pragmatic view handles different kinds of hinges "I have hands," "The Earth has existed for a long time," and "2+2=4." Their truth is seen in how we live them, whether through actions, practices, or the rules of the game.

1) Hinge propositions are the rules that constitute our language game.

2) Within this language game there can be representations of the world.

3) The world is what is said by true sentences.

Removing any reference to "world"

4) Hinge propositions are the rules that constitute a language game that can represent what is said by true sentences.

It seems that such a language game is self-referential.

Quoting Sam26
Moreover, we can't forget OC 206, where Wittgenstein points out that if someone asked, "but is that true" (referring to hinges), we might respond "yes,"


There is a difference between asking is it true that "here is one hand" and asking "is it true that here is one hand".

Asking is it true that "here is one hand"
See OC 204
"Here is one hand" is a hinge proposition because it is a rule that constitutes the language game. The end is not a certain proposition that strikes us as true, it is our acting.


Asking "is it true that here is one hand".
See OC 206
If someone asks us "is it true that here is one hand", we may answer "yes, but I cannot give you any grounds". The expression "here is one hand" in this instance is not being used as a hinge proposition. It is not being used as a rule that constitutes the language game but is being used as a part of the language game.

To my understanding, "here is one hand" can be used both as a rule that constitutes a language game and as an expression within a language game. The first is not truth-apt, but the second is.

True, but they don't doubt that they have the doubt as to whether the Earth exists.


Problem with hinge proposition is vagueness of its definition. There are other propositions that I don't doubt at all, and they are not hinge propositions. For example,

If I won the lottery jackpot last night, I have 24 million pounds in my bank account today.
I didn't win the jackpot.
Therefore, I don't have 24 million pounds in my bank account today.

Above is not a hinge proposition, but it is the absolute true fact (which is verified via the logical reasoning and reality), and I don't doubt it at all. It is exempt from doubting.

There are many ordinary propositions such as above which are exempt from doubts, especially when verified by sense perceptions, personal experience or logical reasoning on the reality.

Reply to Banno You don't follow the post where I referred to OC 205, 206? I'll try to clarify.

I understand that you want to use OC 205 to support your position, viz., that hinges are not true or false. My point is that OC 206 says, "If someone asked us 'but is that true [referring to a hinge]?' we might say 'yes' to him..." OC 206 refers to a response about hinges, and 205 refers to traditional propositions. In other words, hinges (the ground) are not yet true or false in the same way traditional propositions are true or false. He then points out in 206 that despite not being able to call the ground true or false, you can still say they're (hinges) true (206). This indicates to me and others that truth can be ascribed to hinges, just not in a propositional sense. They're like subjective truths that we all hold firm or as indubitable.

What would it mean to say one is certain or one has a conviction, which Wittgenstein points out over and over again, about hinges other than you believe they're true? This is a bedrock truth that cannot be doubted or falsified, which is why they're not like traditional propositions, which can be falsified.

Our differences go a little deeper because my idea of a belief is that it goes beyond propositions. In other words, our actions show our beliefs apart from language.

Wittgenstein defines what we call the hinge proposition as being a proposition that is exempt from doubt.

OC 341. That is to say, the questions that we raise and our doubts depend on the fact that some propositions are exempt from doubt, are as it were like hinges on which those turn.


For Wittgenstein, if "here is one hand" is a hinge proposition and therefore exempt from doubt, there is no reason why "here is no hand" must also be a hinge proposition and therefore exempt from doubt.

Similarly, "here is the Jackpot", "here is no Jackpot", "here are winnings" and "here are no winnings" must also all be hinge propositions and therefore exempt from doubt.

These hinge propositions may be combined into language games:
1) "here is the Jackpot" and "here are winnings"
2) "here is the Jackpot" and "here are no winnings"
3) "here is no Jackpot" and "here are winnings"
4) "here is no Jackpot" and "here are no winnings"

Your particular case is 2) "I didn't win the jackpot"

It is true that your proposition "I didn't win the jackpot" is exempt from doubt.

But I assume that combining two hinge propositions doesn't form a single new hinge proposition.

This is perhaps why "I didn't win the Jackpot" is not a hinge proposition, even though exempt from doubt, as it is a combination of hinge propositons.

As I understand it:

A hinge proposition enables a language game.

A hinge proposition must be exempt from doubt in order to ground the language game.

A language game is contingent because it describes how the world is.

In the mind of the user of the language game, it would be wrong to say that this language game either represents or corresponds with the world. It would be more accurate to say that this language game "is" their world, meaning that there is no other world outside the language game itself.

In other words, we use the language game to understand the world, and this world is nothing other than the language game itself.

Yes, but perhaps for a different reason.

There is language and there is the world.

For the Direct and Indirect Realist, there is a world that exists independently of any human observer. It would seem that for the Direct and Indirect Realist, language alone cannot fully capture or understand the world.

But for Wittgenstein, what is the relation between language and the world?

It seems to me that for Wittgenstein, language "is" the world.

It is not the case that the proposition "here is one hand" is a representation of a world or corresponds to a world, but rather the world is embodied in "here is one hand".

In a sense, a similar concept to that of the Indirect Realist who doesn't perceive a representation of the colour red but directly perceives the colour red.

374. We teach a child "that is your hand", not "that is perhaps (or "probably") your hand". That is how a child learns the innumerable language-games that are concerned with his hand. An investigation or question, 'whether this is really a hand' never occurs to him. Nor, on the other hand, does he learn that he knows that this is a hand.


There is nothing the other side of a world embodied in language.

"Here is one hand" is a hinge proposition not because it is needed to enable a language game that can represent or correspond with a world, but because the world is embodied in the hinge proposition.

What are the implications? We can only understand the world using language. But if the world is our language, and language cannot understand itself, then this inevitably puts a limit on our understanding of the world.

You need more than language for accurate understanding the world i.e. rational thinking and inferring with the observations on the reality.

Language alone can misled folks into the muddle rather than truths on reality. Think of the sad cases where some unthinking folks just read what the internet shady websites says, and accept whatever they say on the topics of even logic, and then just blindly trust them. and even taunt the others' correct ideas.

We need critical thinking and rational inference on the reality coming to our own conclusions on the world. Language is a representational and descriptive tool of the world. Language alone cannot reveal the whole structure of the world.

Your confusion towards propositions is apparent. I suspect it derives from too much veneration of propositions and beliefs.

A proposition is one action amongst many. You can show that there is a hand by using it to pick your nose or by saying "Here is a hand"; much of a muchness.

Almost all beliefs are beliefs that... That is, they are propositional.

What makes a hinge proposition different is that for the purposes of the game in which it is a hinge proposition, it is taken to be true. Your seem to want something more, but what, remains unclear.

The world is totally separate from us, existing on its own never saying anything at all. It is doubtful also if the world would listen to us if we said something to it i.e. the world has nothing to do with language. We just use language to describe it, and communicate with others.

Partial, in that for Wittgenstein some things don't depend on linguistic practice, such as numbers, horses, wolves, days, etc, whilst some things do depend on linguistic practice, such as rules, rights, promises, etc.

Linguistic idealism is the position that our language does not describe an empirical reality that we are aware of through our sense perceptions, but rather our language determines what kind of contact we have we the reality of the world. Linguistic Idealism undermines the traditional Realist/Idealist debate.

For Wittgenstein, the world is not totally separate to the language that we use to describe it.

Hinges are layered. Some hinges, the most basic kind, like "The Earth has existed for more than ten minutes," must be accepted to even have a language or a language game. Here, I'm speaking of the most basic beliefs (such beliefs are the precursors to language) shown only in our actions (although they remain even after language develops), apart from language. The act of sitting on a chair shows my belief in chairs. The act of using my hands shows my belief in hands, etc. This is where hinges start, and they are more fundamental than the hinges that form as part of language. "[I]t is not a kind of seeing on our part; it is our acting, which lies at the bottom of the language game (OC 241). The truth is shown in the actions. This is different from traditional thinking about truth because these truths cannot be doubted or falsified.

A historical individual or institution decided that when someone waves one hand the action is to be named "here is one hand", rather than "here are five fishes", for example. Similar to JL Austin's performative utterance.

With the passage of time, that "here is one hand" indicates the action of waving one hand is now beyond doubt, and is therefore a hinge.

Years later, Moore waves one hand and says "here is one hand"

The proposition "here is one hand" is true if and only if Moore waves one hand.

The action of waving one hand shows the truth of the proposition "here is one hand"

But the proposition "here is one hand" is not the hinge that is exempt from doubt.

Therefore, the action of waving one hand doesn't show the truth of the hinge.

The hinge that is exempt from doubt is that the proposition "here is one hand" indicates the action of waving one hand.

The hinge is neither true nor false. The hinge enables truth and falsity in the language game.

The world is all that is the case. Truth is built in and assertable. Having "hinges" outside of propositions breaches this basic and central tenant, this most central of Wittgenstein's hinge propositions. Here, he is not making a mere observation or assertion but setting up the philosophical game he played throughout his life. He is setting out the extent of the world. Now you want things that are outside the world, that are the case but not true, or true but not the case.

Reply to Banno It is my position that Wittgenstein is offering a more nuanced view of truth that is embedded in our subjective certainties, practices, and language use. His nuanced view takes into account the relationship between language, practice, and reality. This account is a departure from the traditional notions of correspondence and coherence. He doesn’t offer a theory so much as a way of understanding how truth works in our lives. So, truth is more than a propositional notion, it's deeply tied to our actions, both physical and linguistic. We couldn’t even understand propositional truth without these very basic or bedrock shared convictions. They provide the framework that allows the language of traditional propositions to work. Such convictions (hinges) underlie our entire way of thinking, speaking, and acting in the world.

(Subjectivity here isn’t about individualism but about what is shared by all of us, i.e., it's communal agreement.)

Again, sure. This sort of thing is already in 'meaning as use" motif. I'm not aware of his having addressed Tarski directly, and certainly Davidson's view is after and reliant on Wittgenstein.

Unfortunately I don't have access to the Floyd articles on the topics that concern you. The tension between us might be similar to that between prose and proof that she discusses. It's pretty unlikely that W. did not grasp the formal argument, as some have suggested. But it might be mistaken to supose that the tension between formalism and prose is strictly either-or. Gödel uses a notion of "truth" that is independent of proof, while Wittgenstein looks more to some form of constructionism; another tension that you will need to deal with in your new project.

I'll put my previous argument to you again, since it seems to me that it is central, but perhaps not as obvious as I had thought. Briefly and dogmatically...
1. The world is all that is the case. This I take as a view that W. kept throughout his thinking.
2. In the Tractatus, W. argues that there are important aspects of the world that are shown, but not said.
3. In PI, W. adds that there are also things we do, and that these include what we do with words - that it is what we do with words that is important, not abstract and private "meanings".
4. In OC, W. adds that there are some things that we say which ground what we do, including our use of words. These are effectively not about the world, but rather set up the language we use. This is best understood in the terms Anscombe later set out, as a difference in direction of fit.

Now the difficulty faced by the recent fad of reading Wittgenstein as suggesting that there are non-propositional truths is that it is difficult to give instances of things that are true and yet unstatable. And this is a pretty direct consequence of (1) - that the world is all that is the case - the world is what can be stated to be true.

Truth is more than a propositional notion in that it is how the world is, of course - but that is repeating the difference between "the cat is on the mat" and that the cat is on the mat; between making noises and making assertion, between saying and doing.

I don't see that you have provided a notion of truth that is adequate to these tasks, and i think this is so not becasue you have not done enough with "truth", but that you have tried to do too much.



Sam26 April 08, 2025 at 17:12 #981272
Reply to Banno

Point 1:
You seem to agree that truth is more than a propositional notion, tied to our actions, which aligns with Wittgenstein’s meaning as use (PI 43). You point out that this is already present in Wittgenstein’s philosophy, and I agree – it’s a cornerstone of my argument. In OC 204, Wittgenstein says, “It is our acting, which lies at the bottom of the language game.” I build on this by showing how the truth of hinges is demonstrated in our actions. For example, sitting in a chair shows the truth that chairs exist, a prelinguistic certainty (OC 148), whereas linguistic actions – like saying “I know the Earth exists” in a communal context reflect lived certainties (OC 206). Your acknowledgment doesn’t fully address my layered view of hinges, which makes a distinction between prelinguistic and linguistic certainties. This is crucial to understanding how truth operates at different levels of our practices. I’ll return to this point as I address your other critiques.

Point 2:
There is a tension between Godel’s formal notion of truth and Wittgenstein’s constructivist approach, which suggests the need for further investigation. Godel’s incompleteness theorems (1931) rely on objective truth—unprovable statements are true in a mathematical sense, independent of proof within the system. You argue that Wittgenstein leans toward constructivism, which ties truth to our practices (OC 241). However, my analogy between Godel and Wittgenstein is structural. Godel shows that formal systems require unprovable statements to function, and Wittgenstein shows that epistemological systems require unprovable hinges that enable justification and doubt (OC 115). Both systems rely on unprovable foundations despite being in different domains (formal systems vs lived practices). This supports my argument about the limits of human knowledge without conflating the two notions of truth.

Point 3:
You argue that truth is propositional, rooted in the Tractates’ “the world is all that is the case” (T 1), and that hinges are effectively not about the world” but set up our language (as per Anscombe). You trace this through Wittgenstein’s development—PI’s focus on what we do with words (PI 43), and OC’s hinges grounding our language use. I disagree with your interpretation on two grounds. First, your reliance on the Tractatus overlooks Wittgenstein’s evolution in On Certainty. In OC 241, he says, “It is what human beings say that is true and false; and they agree in the language they use. That is not agreement in opinions but in form of life.” Truth is embedded in our communal practices, not just what can be stated. Hinges aren’t merely linguistic setups—they’re tied to the world we live in (OC 94: “I did not get my picture of the world by satisfying myself of its correctness…”). Sitting on a chair shows my belief in chairs, this is an action in the world, not just a language rule.

Second, you claim that hinges can’t be non-propositional truths because truth is statable, which misses my layered view. Prelinguistic hinges, like “Chairs exist,” are shown in actions before language (OC 475: “I want to regard man here as an animal…”). Their truth is in the acting itself—sitting on a chair demonstrates its truth (OC 204). Linguistic hinges, like “I am not a brain in a vat,” are stated, but their truth is still pragmatic—I live as if the world is real. In OC 206, Wittgenstein says we might say ‘yes’ if asked if a hinge is true—we treat it as true because we live it, not because it’s a justified proposition. My view isn’t about unstatable truths; it’s about truths shown in actions, which later we articulate. Your propositional focus overlooks this prelinguistic layer, where truth precedes language.

Point 4:
Finally, you claim I haven’t provided an “adequate” notion of truth, suggesting I’ve tried to do “too much” by extending truth beyond propositions. I believe this is an unfair critique because it doesn’t fully engage with my pragmatic view, which is specific to hinges, not a universal redefinition of truth. I argue that truth for hinges is shown in our actions—physical (sitting on a chair) and linguistic (using words in language games)—and embedded in our forms of life. This isn’t a new theory of truth but a way of understanding how truth functions for hinges, aligning with Wittgenstein’s later philosophy. In OC 204 he emphasizes acting, and in OC 206, he notes we treat hinges as true - as a lived certainty. My layered view ensures this applies to both prelinguistic hinges (truth in acting) and linguistic hinges (truth in language games). Your T-sentence model assumes truth is propositional, but prelinguistic hinges aren’t propositions—their truth is in the acting itself. My notion of truth is adequate for hinges—it captures their lived, communal nature, offering a nuanced perspective on how truth works in our practices, not just in statements.

What makes Moorean propositions ("Here is one hand.") a hinge, according to Wittgenstein, is their status as bedrock certainties. This particular bedrock certainty is prelinguistic (not all hinges are prelinguistic, but bedrock certainties are), i.e., it's shown in our actions. Our actions alone demonstrate our certainty that we have hands. (This is not an objective certainty, i.e., it's subjective and communal, not individualistic, meaning they’re shared in our forms of life.) Many such bedrock hinges fall into this prelinguistic category and they're the foundation for language itself. These prelinguistic certainties or beliefs are a necessary precursor for all our talk of justification and truth (i.e., traditional propositional talk). The subjective certainty in these bedrock hinges is lived, prelinguistic beliefs shown in actions—is equivalent to what we hold to be true in a pragmatic lived sense, but not in the traditional, propositional sense. You still seem to want to think of them in the traditional sense. They don't function like that.

We treat certain actions as true in a very practical way. The act of opening a door shows that we treat this hinge as true in a very practical and pragmatic sense. There is no doubt here, there is just action that reflects our subjective communal certainties.

2) This particular bedrock certainty is prelinguistic (not all hinges are prelinguistic, but bedrock certainties are), i.e., it's shown in our actions


How are you defining "hinge"?

Is the hinge 1) the Moorean proposition "here is one hand", or 2) the prelinguistic bedrock certainty, here is one hand.

Reply to RussellA Here's a rough definition of hinges.

Hinges are layered, arational (arational because they are not subject to the rational processes of justification, doubt, or proof that characterize traditional epistemological theory), foundational convictions shared by all humans within our forms of life that serve as indubitable certainties grounding our epistemological language, systems of doubt, and justification. They exist both prelinguistically and linguistically, with their truth shown through our actions rather than propositional validation.

:smile: I appreciate your definition.

Prelinguistic

In the world are facts, such as i) here is one hand, ii) the apple is green, iii) the mountain is next to the tree.

These facts exist within human Forms of Life. They exist prelinguistically and are beyond doubt. They are bedrock certainties.

Question 1. Are these prelinguistic facts hinges?

The notion of truth is redundant.
If the apple is green then the apple is green.
Nothing is added - if the apple is green then it is true that the apple is green.

Linguistic meaning

Today, that "here is one hand" means here is one hand is beyond doubt.

The notion of truth is redundant
If "here is one hand" means here is one hand then "here is one hand" means here is one hand
Nothing is added - if "here is one hand" means here is one hand then it is true that "here is one hand" means here is one hand.

Linguistic correspondence

"Here is one hand" is a hinge proposition because its meaning is beyond doubt, as we know that it means here is one hand.

"Here is one hand" is true IFF here is one hand

The truth of the proposition "here is one hand" is contingent on there being here is one hand in the world.

Reply to RussellA We can talk about prelinguistic truth in terms of facts by understanding facts as states of affairs that are separate from language, similar to the lived truth of prelinguistic hinges. The fact that “The Earth has one moon” exists as a reality (a fact), and a prelinguistic human’s engagement with it (e.g., navigating by moonlight) reflects a lived belief in that fact, similar to how sitting on a chair reflects the lived truth that “Chairs exist.” This isn’t about hinges corresponding to facts in a propositional sense but about their truth being a lived engagement with facts as prelinguistic realities.

Here is a more detailed definition of bedrock beliefs or bedrock convictions, aka hinges.

Hinges are layered, arational foundational convictions shared by all humans within our form of life. They serve as indubitable certainties grounding our epistemological language, systems of doubt, and justification. Hinges operate on both the prelinguistic and linguistic levels, with their truth shown in our actions rather than in propositional form.

Prelinguistic Hinges: These are the most foundational convictions, such as “Chairs exist” (shown by sitting) or “I have hands” (shown by using them), which are instinctual, prelinguistic beliefs embedded in our actions before language develops (OC 475: “I want to regard man here as an animal…”; OC 148: “Why do I not satisfy myself that I have two feet…? There is no why. I simply don’t. This is how I act”). They form the primary layer, enabling both language and language games by providing the unarticulated certainties on which linguistic practices are built (OC 115: “The game of doubting itself presupposes certainty”).

Linguistic Hinges: These are articulated convictions that develop within language games, such as “I am not a brain in a vat” (OC 114) or “2+2=4,” which remain indubitable and ground specific epistemic or mathematical practices (PI 23). They build on the prelinguistic layer, extending its certainties into linguistic frameworks while retaining their foundational role.

Arational Nature: Hinges are arational, neither true nor false in the traditional epistemological sense because they are not subject to justification or doubt (OC 205: “If the true is what is grounded, then the ground is not true, nor yet false”). They are the “hinges on which our questions turn” (OC 341-343), exempt from the true/false evaluation applied to propositional statements (OC 243: “One says ‘I know’ when one is ready to give compelling grounds… However, with hinges, there is no such possibility”).

Foundational Convictions: Hinges are foundational convictions that anchor our epistemological systems, providing the ungrounded basis for language, doubt, and justification. They are the inherited background against which we distinguish true and false (OC 94: “I did not get my picture of the world by satisfying myself of its correctness…”). In OC 102, Wittgenstein says, “There are propositions which… are expressions of a conviction,” highlighting their role as the untested certainties we live by.

Shared Within Our Form of Life: Hinges are communal, not individualistic, they are subjective certainties shared by all humans within our form of life. The prelinguistic belief in chairs’ existence, shown by sitting, is a universal certainty across humans, persisting even after language develops.

Truth Shown Through Actions: The truth of hinges is pragmatic and lived, shown in our actions, both physical and linguistic, rather than through propositional confirmation. For prelinguistic hinges, truth is in the acting: sitting on a chair shows the truth of “Chairs exist." For linguistic hinges, truth is shown in lived practices within language games: treating the world as real reflects the truth of “I am not a brain in a vat” (OC 206: “If someone asked us ‘but is that true [referring to a hinge]?’ we might say ‘yes’ to him…”). This truth is a new category, pragmatic, lived truth, quite distinct from propositional truth, as it exists apart from language for prelinguistic hinges and remains action-based for linguistic hinges.

A valuable post. If I may add my thoughts to your conversation.

I am using "here is one hand" to indicate a proposition in language and (here is one hand) to indicate something in the world.

The requirement for action is limited

In the beginning, the meaning of the proposition "here is one hand" can only be shown by an action, such as waving one hand or pointing to the one hand. In other words, in the beginning, how would anyone know that "here is one hand" means (here is one hand) rather than (here is one finger), unless there was some kind of action?

However, once the process has been repeated a sufficient number of times, then it may become a certainty beyond doubt in the minds of the community that "here is one hand" means (here is one hand). This is along the lines of JL Austin's Performative Utterance.

However, in the world, no action is required to know that (here is one hand) is a certainty beyond doubt. If I see (here is one hand), then there is no uncertainty in my mind that (here is one hand). I don't need to see it wave, be pointed at or open a door for me to be certain beyond doubt that (here is one hand). (Here is one hand) may remain static for me to know beyond doubt that (here is one hand).

The truth of (here is one hand) is no different to the truth of (an apple). As we don't say that (an apple) is true, there is no reason that say that (here is one hand) is true. Is (the Moon) true, is (Mount Everest) true? Then why should (here is one hand) be true?

Prelinguistically, action is not required to know (here is one hand) and in addition, truth is redundant.

Here's another simple way to explain Wittgenstein's hinges.

Imagine opening a door; you don't ask yourself if the hinges will do their job by holding the weight of the door and allowing it to swing, you simply trust they'll do the job. Now compare this to our everyday beliefs, you don't consider whether or not the ground won't vanish under your feet, or whether the person you're talking to really exists. These bedrock assumptions are what we call hinges, and they're the grounding of every action and question you ever ask, yet you rarely stop to justify them.

Wittgensteinian hinges aren't based on theories or logical proofs. They're the unspoken bedrock certainties that make epistemology possible. If someone asked you, "How do you know the Earth will be here tomorrow?" You'd probably reply, "I just do." Questioning hinges feels absurd, yet without them, you couldn't even begin to act or think.

Wittgenstein is making a profound point. Just as the door would fail to function without its hinges, so would our entire system of thought or epistemology collapse if we tried to justify all of our bedrock convictions. Hinges are the silent pillars holding everything up, everything we know, and we rarely notice them.

Wittgenstein's Hinges and Gödel's Unprovable Statements
By: @Sam26
Abstract

In Ludwig Wittgenstein's final notes, published posthumously as On Certainty (1969), Wittgenstein introduces the concept of hinge propositions as foundational certainties that lie beyond justification and doubt (OC 341-343). These certainties support our language-games and epistemic practices, offering a distinctive perspective on knowledge that challenges traditional epistemology's demand for universal justification. I argue for a structural parallel between Wittgenstein's hinges and Gödel's 1931 incompleteness theorems, demonstrating that consistent mathematical systems contain true statements that cannot be proven within those systems. Both thinkers uncover fundamental limits to internal justification: Wittgenstein shows that epistemic systems rest on unjustified certainties embedded in our form of life, while Gödel proves that mathematical systems require axioms that cannot be demonstrated within the system itself. Rather than representing failures of reasoning, these ungrounded foundations serve as necessary conditions that make systematic inquiry possible. This parallel suggests that foundational certainties enable rather than undermine knowledge, pointing to a universal structural feature of how such systems must be grounded. This analysis has implications for reconsidering the nature of certainty across epistemology and the philosophy of mathematics.

Introduction
We often perform actions without hesitation, such as sitting on a chair or picking up a pencil, without questioning the existence of either. This unthinking action illustrates Wittgenstein's concept of a hinge proposition, a fundamental certainty that supports our use of language and epistemological language-games. Wittgenstein compares hinge propositions to the hinges that enable a door to function; these certainties provide the underlying support for the structures of language and knowledge, remaining unaffected by the need for justification.

Wittgenstein's hinges bear a remarkable resemblance to Gödel's incompleteness theorems, revealing unprovable mathematical statements. This resemblance points to deeper questions about how both domains handle foundational issues. Both Wittgenstein and Gödel uncover limits to internal justification, a connection I will examine.

Traditional epistemology often misinterprets hinges by forcing them into a true/false propositional role, neglecting their foundational status embedded in our epistemic form of life. These bedrock assumptions precede argument or evidence, forming the foundational elements of our epistemic practices. Similarly, Gödel's incompleteness theorems showed that any consistent arithmetic system contains true statements unprovable within the system and cannot demonstrate its own consistency.

This connection is significant because it highlights the boundary between what counts as bedrock for epistemic and mathematical systems. Both rest on certainties that lie beyond justification, certainties that are not flaws in reasoning but necessary foundations that make knowledge claims possible. This paper argues that ungrounded certainties enable knowledge, rather than undermining it, and that hinges and Gödel's unprovable statements serve a similar purpose. By examining the parallels between Wittgenstein and Gödel, particularly the role of unprovable foundations and the need for external grounding, this paper sheds light on the nature of certainty in our understanding of both epistemology and mathematics.

Section 1: Hinges and Their Foundational Role

Wittgenstein's concept of hinge propositions is crucial to his thinking, particularly in the context of epistemology. In On Certainty, Wittgenstein introduces the idea of hinges as certainties that ground our epistemic practices. While Wittgenstein never explicitly distinguishes types of hinges, his examples suggest a distinction between nonlinguistic and linguistic varieties, revealing different levels of fundamental certainties.

Nonlinguistic hinges represent the most basic level of certainty, bedrock assumptions that ground our actions and interactions with the world. These are not expressed as propositions subject to justification or doubt but embodied in unreflective action. For instance, the certainty that the ground will support us when we walk is a nonlinguistic hinge that enables movement without hesitation. Similarly, our unthinking confidence that objects will behave predictably, that chairs will hold our weight, that pencils will mark paper, represents this bedrock level of certainty. These hinges operate beneath the level of articulation, forming the silent background against which all conscious thought and language become possible.

Building upon this bedrock foundation, linguistic hinges operate at a more articulated but less fundamental level. These are certainties embedded within our language-games and cultural practices, often taking the form of basic statements like "I have two hands" or "The Earth exists." Unlike nonlinguistic hinges, these can be spoken and seem propositional, yet they resist the usual patterns of justification and doubt. Other examples include statements such as "I am a human being" or "The world has existed for a long time," assertions that appear to convey information but function more as structural supports for discourse than as ordinary claims requiring evidence.

These two types of hinges show how certainty operates at different levels in grounding knowledge. Nonlinguistic hinges form the deepest stratum, revealing the unquestioned backdrop that makes any form of questioning possible. Linguistic hinges, while still foundational, represent a layer above bedrock that anchors shared discourse within specific contexts. Both types resist justification, but their resistance stems from different sources: nonlinguistic hinges from their pre-rational embodiment in action, linguistic hinges from their structural role within our language-games.

Wittgenstein breaks with traditional epistemology here. Rather than viewing these certainties as beliefs requiring justification, he recognizes them as the ungrounded ground that makes justification itself possible. He notes, "There is no why. I simply do not. This is how I act" (OC 148). Doubting these hinges would collapse the very framework within which doubt makes sense, like attempting to saw off the branch on which one sits.

A crucial distinction emerges between subjective and objective dimensions of these certainties. While our relationship to hinges involves unquestioning acceptance, this certainty is not merely psychological. These assumptions are shaped by our interactions with a world that both constrains and enables our practices. The certainty reflected in our actions has an objective component, as it emerges from our shared engagement with reality and proves itself through the successful functioning of our practices.

This interpretation of hinges as operating at different foundational levels finds support in recent Wittgenstein scholarship, though it diverges from some prominent readings. Danièle Moyal-Sharrock argues that hinges are fundamentally non-propositional, existing as lived certainties rather than beliefs or knowledge claims (Moyal-Sharrock 2004). While my distinction between nonlinguistic and linguistic hinges aligns with her emphasis on the embodied, pre-propositional character of our most basic certainties, I suggest that some hinges do function at a more articulated level within language-games, even if they resist standard justification patterns.

Duncan Pritchard's interpretation emphasizes hinges as commitment-constituting rather than knowledge-constituting, arguing they represent a distinct epistemic category that enables rather than constitutes knowledge (Pritchard 2016). This view supports the parallel with Gödel's axioms: both hinges and mathematical axioms function as enabling commitments that make systematic inquiry possible without themselves being objects of that inquiry. The mathematical case strengthens Pritchard's insight by showing how even formal domains require such commitment-constituting foundations.

This analysis extends beyond epistemology to reveal a striking parallel with Gödel's incompleteness theorems, which demonstrate analogous limits within formal mathematical systems. Just as Gödel showed that mathematical systems rely on axioms that cannot be proven within those systems, Wittgenstein's hinges reveal that epistemic systems rest on certainties that cannot be justified internally. This comparison suggests a fundamental structural limitation in rational grounding, whether in mathematics or human knowledge, and invites reconsideration of what it means for knowledge to be properly grounded.

Section 2: Gödel’s Unprovable Statements as Mathematical Hinges

Gödel's incompleteness theorems, published in 1931, establish fundamental limits within formal systems, revolutionizing our understanding of mathematical foundations. Gödel demonstrated that within any consistent system of arithmetic, there will always be statements that are true under the standard interpretation but cannot be proven within the system itself. For instance, the statement asserting the system's own consistency, a meaningful mathematical claim about the system's properties, cannot be demonstrated within that system, even if the system is indeed consistent. Moreover, no such system can demonstrate its own consistency. Such statements are meaningful propositions with definite truth values that reveal structural limitations inherent to formal systems. This limitation persists even when systems are extended. Adding new axioms to prove previously unprovable truths creates strengthened systems that, if consistent and sufficiently powerful, generate their own sets of true but unprovable statements. The cycle of incompleteness is thus perpetual, revealing not a flaw in particular systems but a structural feature of formal mathematics itself.

This limitation mirrors Wittgenstein's hinges in important ways. Just as hinges are certainties that cannot be justified within the epistemic systems they support, Gödel's results show that mathematical systems require axiomatic starting points that cannot be proven within those systems. The Peano axioms, which establish the foundation for arithmetic, exemplify this necessity. These axioms are not accepted because they are provable; they cannot be proven within the systems they generate. Rather, they are adopted as systematic starting points that enable mathematical development, chosen because they make possible coherent, productive systems.

The parallel extends to the necessity of external acceptance. Gödel's systems require axioms accepted from outside the formal system itself, while Wittgenstein's hinges are certainties not arrived at through investigation but accepted as part of our form of life (OC 138). In both cases, what enables the system lies beyond the system's internal capacity for justification. Mathematical axioms and epistemic hinges both function as ungrounded grounds, foundational elements that make systematic inquiry possible precisely because they are not themselves subject to the forms of scrutiny they enable.

Yet there is an important difference here: mathematical axioms are typically chosen for their elegance, consistency, and power to generate interesting mathematics, while hinges appear more embedded in contingent cultural and biological practices. Yet this difference strengthens rather than weakens the parallel. If even mathematics, often considered the paradigm of rigorous proof, requires unjustified foundational elements, how much more must everyday understanding rely on unexamined certainties? The universality of this structural requirement across domains as different as formal mathematics and lived experience suggests a fundamental feature of how systems of thought must be organized.

Both domains thus reveal that functioning without such foundational elements is implausible. Mathematical systems risk incoherence without axiomatic starting points, just as epistemic practices risk collapse without the bedrock certainties that Wittgenstein identifies. The parallel illuminates a shared structural necessity: systematic thought requires ungrounded foundations that enable rather than undermine the possibility of reasoning within those systems.

Section 3: Beyond Internal Justification: A Cross-Domain Analysis

Both Wittgenstein and Gödel reveal that justification operates within boundaries, where certain elements serve as foundations that cannot be further justified within their respective systems. Both thinkers expose a basic structural feature of systematic thought: the impossibility of a complete system of justification in either domain.

Traditional approaches to knowledge often assume that proper justification requires tracing claims back to secure foundations that are themselves justified. This assumption generates the classical problem of infinite regress: any attempt to justify foundational elements through further reasoning creates an endless chain of justification that never reaches secure ground. Both Wittgenstein's hinges and Gödel's axioms reveal why this demand for complete internal justification is not merely difficult but impossible in principle.

As Wittgenstein observes, "There is no why. I simply do not. This is how I act" (OC 148). This insight captures something crucial about the nature of foundational certainties: they are pre-rational in the sense that they precede and enable rational discourse rather than emerging from it. Hinges are not conclusions we reach through reasoning but lived realities that make reasoning possible. Similarly, mathematical axioms are not theorems we prove but starting points we adopt to make proof possible.

There is an important difference between these domains. Hinges emerge from contingent practices embedded in particular forms of life, while mathematical axioms are selected through systematic considerations within formal contexts. Hinges reflect the biological and cultural circumstances of human existence, whereas axioms reflect choices made for their mathematical power and elegance. If anything, this difference makes the parallel more compelling by demonstrating its scope: if even the most rigorous formal disciplines require unjustified starting points, the necessity of such foundations in everyday knowledge becomes even more apparent.

This cross-domain similarity reveals what appears to be a universal structural requirement. Systems of thought, whether formal mathematical theories or practical epistemic frameworks, cannot achieve complete self-justification. They require external elements that are not justified within the system but make systematic inquiry within that framework possible. Rather than representing failures or limitations, these unjustified foundations function as enabling conditions that make coherent thought and practice possible.

Recognizing this structural necessity transforms how we understand the relationship between certainty and knowledge. Instead of viewing unjustified elements as epistemological problems to be solved, we can understand them as necessary features that allow knowledge systems to function. Both mathematical proof and everyday understanding depend on foundations that lie beyond their internal capacity for justification, yet this dependence enables rather than undermines their respective forms of systematic inquiry.

Conclusion

I have argued for a fundamental parallel between Wittgenstein's hinges and Gödel's incompleteness results: both demonstrate that systematic thought requires ungrounded foundations. By examining how epistemic and mathematical systems share this structural feature, we gain insight into the nature of foundational certainties across domains of human understanding.

The parallel between these seemingly distinct philosophical insights suggests that the limits of internal justification are not accidental features of particular systems but necessary conditions for systematic thought. Recognizing this gives us a more realistic picture of how knowledge actually functions, not through endless chains of justification reaching some ultimate ground, but through practices and formal systems that rest on foundations lying beyond their internal scope.

Rather than viewing these limits as philosophical problems requiring solutions, this analysis suggests embracing them as structural necessities that make knowledge possible. Wittgenstein's hinges ground our epistemic practices in the lived realities of human existence, while Gödel's axioms ground mathematical systems in choices that prove their worth through the coherent theories they generate. Both reveal that the search for completely self-grounding systems is not merely difficult but misconceived.

I believe this perspective has broader implications for understanding certainty and knowledge. It suggests that the interplay between grounded and ungrounded elements is not a flaw in human reasoning but a fundamental feature of how systematic understanding must be structured. By recognizing this necessity, we can develop more nuanced approaches to foundational questions in epistemology, philosophy of mathematics, and potentially other domains where the relationship between systematic inquiry and its enabling conditions remains philosophically significant.

Very very good. Your explanations of both Wittgenstein and Gödel are clear and crisp. That is, there's an admirable brevity to both, without loss of import.

While I still have some reservations about thinking of Gödel sentences as foundational, I have great sympathy for your conclusion. The belief in an ultimate grounding for our rational systems is fundamentally flawed, such that there must always be things taken as granted rather than demonstrated.

You set out clearly an issue that is fundamental to rationality.

I'm not sure what you mean by "...there can be nothing in common between the various language games." Your second point "...that not all language games involve justification" is true, but all language games involving knowledge claims do involve some sort of justification (logic, linguistic training, sensory experience, testimony, etc.). Unless you mean there are uses of the word knowledge that aren't epistemological, then I agree.

If there are variable language games, are there also variable human forms of life that play those games, or is there but one?

If there are many, then we cannot know who shares our form, and so we cannot know that we are playing a language game at all. My conversation with a parrot isn't public use.

If you say there is only one human form of life, then that belief must itself be a hinge, because we cannot derive it from language use (which presupposes it), and we cannot claim to know it empirically without violating Wittgenstein’s broader rejection of a metaphysical correspondence theory.

I beleive there are many. But if so, how did Wittgenstein come to know that there are language games? Perhaps from the experience of initially finding a set of discursive practices within a foreign community to be incoherent, and then later learning how to engage with that form of life. This may have led him to surmise that if the sense of meaning of word use is only contingently grounded within a particular language game, then even within that game, reference to pre-existing rules and criteria of meaning of words do not guarantee how they will be understood.

With regard to my conversation with a parrot (or with an A.I.), to the extent that I claim that I understand the parrot and the parrot understands me, I must be drawing from some already available normative discursive structure of meaning, which is likely to come from the language games I share with my human discursive community. Isnt this what we do when we interpret our pet’s behaviors in anthropomorphic terms? Which is not to say that we can’t enter into a language game directly with our pet dog.

Wittgenstein’s form of life refers to shared practices, behaviors, and instinctive foundations that make meaning possible, and this is true whether cultural (like rituals) or universal (like pain reactions). These forms of life give rise to distinct language games, viz., rule-governed and flexible ways of speaking within these activities (e.g., science, chess, or humor). Forms of life vary across cultures and domains; it’s crucial to stress that not all are rigidly rule-bound; some are organic (e.g., grieving), and boundaries often blur. There is no single, overarching form of life for Wittgenstein. I believe he rejects the idea of a universal logic or framework underpinning all language and meaning. Instead, meaning emerges from multiple and diverse forms of life, each with its own internal rules or norms. For instance, the language games of religious belief and scientific proof operate differently, with no master form to reconcile them. While overlaps exist (e.g., counting in math and carpentry), these practices resist being flattened into one system. I guess you could say the key takeaway is pluralism: meaning is always local, grounded in the practical and contextual ways we live and speak.

Perhaps a form of life can be understood via Witt’s description of a family of resemblances, which ties together discrete games on the basis of commonalities that are intertwined but not reducible to a single shared thread:


66. Consider for example the proceedings that we call "games". I mean board-games, card-games, ball-games, Olympic games, and so on. What is common to them all?—Don't say: "There must be something common, or they would not be called 'games' "—but look and see whether there is anything common to all.—For if you look at them you will not see something that is common to all, but
similarities, relationships, and a whole series of them at that. To repeat: don't think, but look!—Look for example at board-games, with their multifarious relationships. Now pass to card-games; here you find many correspondences with the first group, but many common features drop out, and others appear. When we pass next to ball­games, much that is common is retained, but much is lost.—Are they all 'amusing'?

Compare chess with noughts and crosses. Or is there always winning and losing, or competition between players? Think of patience. In ball games there is winning and losing; but when a child throws his ball at the wall and catches it again, this feature has disappeared. Look at the parts played by skill and luck; and at the difference between skill in chess and skill in tennis. Think now of games like ring-a-ring-a-roses; here is the element of amusement, but how many other characteristic features have disappeared! And we can go through the many, many other groups of games in the same way; can see how similarities crop up and disappear. And the result of this examination is: we see a complicated network of similarities overlapping and criss-crossing: sometimes overall similarities, sometimes similarities of detail.

67. I can think of no better expression to characterize these similarities than "family resemblances"; for the various resemblances between members of a family: build, features, colour of eyes, gait, temperament, etc. etc. overlap and criss-cross in the same way.— And I shall say: 'games' form a family.

Perhaps a form of life can be understood via Witt’s description of a family of resemblances, which ties together discrete games on the basis of commonalities that are intertwined but not reducible to a single shared thread:


Yep. Quite agree.

Here are all the mentions on PI:

19. It is easy to imagine a language consisting only of orders and
reports in battle.—Or a language consisting only of questions and
expressions for answering yes and no. And innumerable others.——
And to imagine a language means to imaginea form of life.


241. "So you are saying that human agreement decides what is
true and what is false?"—It is what human beings say that is true and
false; and they agree in the language they use. That is not agreement in
opinions but in form of life.

i
One can imagine an animal angry, frightened, unhappy, happy,
startled. But hopeful? And why not?
A dog believes his master is at the door. But can he also believe his
master will come the day after to-morrow?—And what can he not do
here?—How do I do it?—How am I supposed to answer this?
Can only those hope who can talk? (only those who have mastered
the use of a language. That is to say, the phenomena of hope are modes
of this complicated form of life. (If a concept refers to a character of
human handwriting, it has no application to beings that do not write.)

And from OC:

357. One might say: " 'I know' expresses comfortable certainty, not the certainty that is still struggling."

358. Now I would like to regard this certainty, not as something akin to hastiness or superficiality, but as a form of life. (That is very badly expressed and probably badly thought as well.)


So not synonymous with "language game", but more the ground on which they take place.

for example, demonstrating how our methods of justification apply across various language games within our form of life.


My OP on two ways to do philosophy is along these lines.

Explanation - or justification - requires a contrast between what is explained and the explanation. For an explanation to function it must take what is being explained as granted - an explanation as to why the wasabi plants are thriving grants that the wasabi plants are thriving. The explanation explains and accepts something external to itself.

What our explanations - justifications - have in common is that there is something to justify. What our language games have in common is that they are embedded in the world, and together they make a form of life.

Reply to Sam26 This strikes me as backdooring the beetle back in. The lion's language is meaningless not because it's gibberish, but it's because he doesn't share our form of life. This means it's not langauge misuse that identifies his seperate life form, but it's his thought processes brought about by some metaphysical difference in the lion.

If we're going to rely upon metaphysical similarity to create meaningful language, why not leave it at the beetle?

I don’t know that Witt would want to separate the perception of things from the things themselves. He discusses this in relation to the duck-rabbit drawing in his analysis of what it means to ‘see something as’. Rather than our perception being an interpretation or perception of something external to it (a pre-existing something), the ‘seeing as’ is fundamental.
Banno June 24, 2025 at 00:56 #996673
Reply to Joshs I think I agree.

But I walk away from "perception" because it is seen as private. Seems to me that form a Wittgensteinian perspective, perception as a private experience drops out of the language game.

That is, roughly, that if what counts as a block is constituted by the language game, then so is what is perceived as a block.

Neither the block nor the perception of block are outside of the game.

Not as clear as I'd like. This is not to say that there is nothing more than language. There certainly are blocks.

But this doesn't address the meta element of the form of life, which is critical to holding the system together. The Wittgensteinian enterprise is to dispense with the relevance of the metaphysical as the foundation of meaning, but if it creeps back in, then it has failed.

To address the form of life in your Gavagai example would require a linguist who is attempting to interpret the language not of a foreign people but of a lion. The lion represents the being with a differing form of life, who, per Wittgenstein's clear statement, we would not understand. The Gavagai example is no different from French to English to German. That is, all those folks share a form of life. We're looking for those who don't.

Consider AI. You can speak back and forth with AI, with full understanding, but I submit you are not playing a language game with ChatGPT. It is a lion. It lacks your form of life. What this means is that there is a metaphysical anchor to meaning. It is use by something like you. What is like you isn't decipherable by simply looking at the person, the lion, or the dolphin. It is something inherent within that being that processes like or not like you. If not, you are left with a convincing parrot, lion, AI program, or Searle's Chinese speakers as playing language games, which they are not.

So my problem here is that if we're going to say that we're taking as a hinge belief the uniformity of thought processes among various people, why not just make it a hinge belief that we truly have the same beetle metaphysically. If we're going to reduce this down to an object of foundation/hinge/faith, why choose one method over the other?

A language game - moving blocks, counting apples - is not confined to language.

I think I see. And thanks for the reply.

Language itself is not the game. Interesting. Because “a language game involves more than just language.”

Does this then make sense:

In the case of building with blocks, we can construct a language game wherein two people work together and one yells “block” and as the other person hears the language and plays the game of building the other then brings the block because he heard “block” and knows the game. The 1. language game of building here involves 2. language and 3. blocks (likely among other things and more language and more complex gaming). But it takes 2 and 3 before 1 can emerge.

And when you say “we are always already in a language” (which I think you said a few times), does that mean we are always sort of given into a language game, already playing by communicating through language, or does it mean something else, like in a language but not in a language game? I took it to mean we are already in a game when we are thinking/communicating in a language about the world.

What do you mean by “already in a language” then?

This is what the eliminativist says about consciousness. Of course there are demonstrations, that's why it was the dominant theory. But if one presupposes epistemic standards that remove it by default (much as behaviorism and eliminativism make consciousness epiphenomenal by default) one hasn't done much of anything except beg the question.

And that's not really the point. If such a faculty is accepted as a hinge proposition, it shows that the theory of hinge proposition itself is not presuppositionless, but fails to obtain given certain assumptions.

Where the empiricist tradition has ended up, bottoming out in denying consciousness, denying truth as anything more than a token in "games," etc., along with the radical skepticism engendered by arguments from underdetermination, which are undefeatable given its premises (likewise for Hume's attack on induction), is arguably a reductio conclusion against the initial assumptions.

So a rabbi and an anthropologist walk into a bar, and Ludwig asks "why are you here?" They each say "it's the right time to be here. " And they don't communicate because their forms of life vary, despite the syntactically correct response, yet the question and answer were entirely different to each.

The question then is where is this form of life? You say, I don't care where it is, I just need to know that it is. I see it in the way the anthropologist looks at and speaks of evolution and the way the rabbi prays and reads his Talmud.

But my response is it absolutely matters where it is because unlike meaning of language being use, form of life is not in behavior. It is assumed from behavior, but not caused by behavior, meaning a rabbi who mimics an anthropologist to avoid persecution remains a rabbi.

Form of life is inherent in the being. ChatGPT given time will be spoken from the perfect robot, whose behavior will perfectly mimic the human's. I contend it will not use langauge. It is a lion.

The form of life is what we do. It's not here nor there. Consider:
OC:355. A mad-doctor (perhaps) might ask me "Do you know what that is?" and I might reply "I know that it's a chair; I recognize it, it's always been in my room". He says this, possibly, to test not my eyes but my ability to recognize things, to know their names and their functions. What is in question here is a kind of knowing one's way about. Now it would be wrong for me to say "I believe that it's a chair" because that would express my readiness for my statement to be tested. While "I know that it..." implies bewilderment if what I said was not confirmed.

The form of life as "a kind of knowing one's way about".

This is an updated version of my paper with corrections. The edits tighten the Gödel side (incompleteness + no from-within proof of consistency) and clarify the analogy as a limit on internal vindication, not “axioms can’t be proved.” That keeps the hinge–Gödel connection exactly as I intended.

Wittgenstein's Hinges and Gödel's Unprovable Statements

Abstract

In Ludwig Wittgenstein's final notes, published posthumously as On Certainty (1969), Wittgenstein introduces the concept of hinge propositions as foundational certainties that lie beyond justification and doubt (OC 341-343). These certainties support our language-games and epistemic practices, offering a distinctive perspective on knowledge that challenges traditional epistemology's demand for universal justification. I argue for a structural parallel between Wittgenstein's hinges and Gödel's 1931 incompleteness theorems, demonstrating that any consistent, effectively axiomatized system capable of arithmetic contains arithmetical truths that cannot be proven within the system. Both thinkers uncover fundamental limits to internal justification: Wittgenstein shows that epistemic systems rest on unjustified certainties embedded in our form of life, while Gödel shows that any consistent, effectively axiomatized system strong enough for arithmetic has statements it cannot settle from within and cannot, from within itself, prove its own consistency. Rather than representing failures of reasoning, these ungrounded foundations serve as necessary conditions that make systematic inquiry possible. This parallel suggests that foundational certainties enable rather than undermine knowledge, pointing to a universal structural feature of how such systems must be grounded. This analysis has implications for reconsidering the nature of certainty across epistemology and the philosophy of mathematics.

Introduction

We often perform actions without hesitation, such as sitting on a chair or picking up a pencil, without questioning the existence of either. This unthinking action illustrates Wittgenstein's concept of a hinge proposition, a fundamental certainty that supports our use of language and epistemological language-games. Wittgenstein compares hinge propositions to the hinges that enable a door to function; these certainties provide the underlying support for the structures of language and knowledge, remaining unaffected by the need for justification.

Wittgenstein's hinges bear a remarkable resemblance to Gödel's incompleteness theorems, revealing unprovable mathematical statements. This resemblance points to deeper questions about how both domains handle foundational issues. Both Wittgenstein and Gödel uncover limits to internal justification, a connection I will examine.

Traditional epistemology often misinterprets hinges by forcing them into a true/false propositional role, neglecting their foundational status embedded in our epistemic form of life. These bedrock assumptions precede argument or evidence, forming the foundational elements of our epistemic practices. Similarly, Gödel’s incompleteness theorems show that any consistent, effectively axiomatized system capable of arithmetic contains arithmetical truths unprovable within the system and cannot, from within itself, prove its own consistency.

This connection is significant because it highlights the boundary between what counts as bedrock for epistemic and mathematical systems. Both rest on certainties that lie beyond justification, certainties that are not flaws in reasoning but necessary foundations that make knowledge claims possible. This paper argues that ungrounded certainties enable knowledge, rather than undermining it, and that hinges and Gödel's unprovable statements serve a similar purpose. By examining the parallels between Wittgenstein and Gödel, particularly the role of unprovable foundations and the need for external grounding, this paper sheds light on the nature of certainty in our understanding of both epistemology and mathematics.

Section 1: Hinges and Their Foundational Role

Wittgenstein's concept of hinge propositions is crucial to his thinking, particularly in the context of epistemology. In On Certainty, Wittgenstein introduces the idea of hinges as certainties that ground our epistemic practices. While Wittgenstein never explicitly distinguishes types of hinges, his examples suggest a distinction between nonlinguistic and linguistic varieties, revealing different levels of fundamental certainties.

Nonlinguistic hinges represent the most basic level of certainty, bedrock assumptions that ground our actions and interactions with the world. These are not expressed as propositions subject to justification or doubt but embodied in unreflective action. For instance, the certainty that the ground will support us when we walk is a nonlinguistic hinge that enables movement without hesitation. Similarly, our unthinking confidence that objects will behave predictably, that chairs will hold our weight, that pencils will mark paper, represents this bedrock level of certainty. These hinges operate beneath the level of articulation, forming the silent background against which all conscious thought and language become possible.

Building upon this bedrock foundation, linguistic hinges operate at a more articulated but less fundamental level. These are certainties embedded within our language-games and cultural practices, often taking the form of basic statements like "I have two hands" or "The Earth exists." Unlike nonlinguistic hinges, these can be spoken and seem propositional, yet they resist the usual patterns of justification and doubt. Other examples include statements such as "I am a human being" or "The world has existed for a long time," assertions that appear to convey information but function more as structural supports for discourse than as ordinary claims requiring evidence.

These two types of hinges show how certainty operates at different levels in grounding knowledge. Nonlinguistic hinges form the deepest stratum, revealing the unquestioned backdrop that makes any form of questioning possible. Linguistic hinges, while still foundational, represent a layer above bedrock that anchors shared discourse within specific contexts. Both types resist justification, but their resistance stems from different sources: nonlinguistic hinges from their pre-rational embodiment in action, linguistic hinges from their structural role within our language-games.

Wittgenstein breaks with traditional epistemology here. Rather than viewing these certainties as beliefs requiring justification, he recognizes them as the ungrounded ground that makes justification itself possible. He notes, "There is no why. I simply do not. This is how I act" (OC 148). Doubting these hinges would collapse the very framework within which doubt makes sense, like attempting to saw off the branch on which one sits.

A crucial distinction emerges between subjective and objective dimensions of these certainties. While our relationship to hinges involves unquestioning acceptance, this certainty is not merely psychological. These assumptions are shaped by our interactions with a world that both constrains and enables our practices. The certainty reflected in our actions has an objective component, as it emerges from our shared engagement with reality and proves itself through the successful functioning of our practices.

This interpretation of hinges as operating at different foundational levels finds support in recent Wittgenstein scholarship, though it diverges from some prominent readings. Danièle Moyal-Sharrock argues that hinges are fundamentally non-propositional, existing as lived certainties rather than beliefs or knowledge claims (Moyal-Sharrock 2004). While my distinction between nonlinguistic and linguistic hinges aligns with her emphasis on the embodied, pre-propositional character of our most basic certainties, I suggest that some hinges do function at a more articulated level within language-games, even if they resist standard justification patterns.

Duncan Pritchard's interpretation emphasizes hinges as commitment-constituting rather than knowledge-constituting, arguing they represent a distinct epistemic category that enables rather than constitutes knowledge (Pritchard 2016). This view supports the parallel with mathematical axioms: both hinges and mathematical axioms function as enabling commitments that make systematic inquiry possible without themselves being objects of that inquiry. The mathematical case strengthens Pritchard's insight by showing how even formal domains require such commitment-constituting foundations.

This analysis extends beyond epistemology to reveal a striking parallel with Gödel's incompleteness theorems, which demonstrate analogous limits within formal mathematical systems. Just as Gödel showed that sufficiently strong systems face statements they cannot settle and cannot prove their own consistency from within, Wittgenstein's hinges reveal that epistemic systems rest on certainties that cannot be justified internally. This comparison suggests a fundamental structural limitation in rational grounding, whether in mathematics or human knowledge, and invites reconsideration of what it means for knowledge to be properly grounded.


Section 2: Gödel’s Unprovable Statements and a Hinge-Like Limit

Gödel’s incompleteness theorems (1931) mark hard limits within formal theories. In any consistent, effectively axiomatized system strong enough for arithmetic, there are arithmetical statements that are true under the standard interpretation but not provable by the system’s own rules; and no such system can, from within itself, prove its own consistency. These are structural limits, not defects of a particular axiom set, and they persist under extension: add new axioms to settle an undecidable statement and—so long as the strengthened theory remains consistent and comparably strong—new undecidable statements arise in turn.

This limitation mirrors Wittgenstein’s hinges in an important way. Just as hinges are certainties that are not justified by the very practices they enable, Gödel identifies a limit on internal vindication: even very strong formal systems have truths they cannot prove and cannot establish their own consistency from within. The point is not that axioms ought to be proven (axioms are adopted), but that every practice—including mathematics—runs on enabling commitments that do not receive their warrant from the inferential moves they make possible.

Independently of Gödel, formal theories begin with axioms that are adopted rather than proved. Gödel’s results then add a further limit: even once the axioms are fixed, some truths remain unprovable and the theory cannot certify its own consistency from within. Wittgenstein’s hinges play an analogous enabling role in our epistemic life: background certainties we do not arrive at by inference but that make inference possible.

Yet there is an important difference here: mathematical axioms are typically chosen for their elegance, consistency, and power to generate interesting mathematics, while hinges appear more embedded in contingent cultural and biological practices. Yet this difference strengthens rather than weakens the parallel. If even mathematics, often considered the paradigm of rigorous proof, requires unjustified foundational elements, how much more must everyday understanding rely on unexamined certainties? The universality of this structural requirement across domains as different as formal mathematics and lived experience suggests a fundamental feature of how systems of thought must be organized.

Both domains thus reveal that functioning without such foundational elements is implausible. Mathematical systems risk incoherence without axiomatic starting points, just as epistemic practices risk collapse without the bedrock certainties that Wittgenstein identifies. The parallel illuminates a shared structural necessity: systematic thought requires ungrounded foundations that enable rather than undermine the possibility of reasoning within those systems.


Section 3: Beyond Internal Justification: A Cross-Domain Analysis

Both Wittgenstein and Gödel reveal that justification operates within boundaries, where certain elements serve as foundations that cannot be further justified within their respective systems. Both thinkers expose a basic structural feature of systematic thought: the impossibility of a complete system of justification in either domain.

Traditional approaches to knowledge often assume that proper justification requires tracing claims back to secure foundations that are themselves justified. This assumption generates the classical problem of infinite regress: any attempt to justify foundational elements through further reasoning creates an endless chain of justification that never reaches secure ground. Both Wittgenstein's hinges and Gödel’s incompleteness results reveal why this demand for complete internal justification is not merely difficult but impossible in principle.

As Wittgenstein observes, "There is no why. I simply do not. This is how I act" (OC 148). This insight captures something crucial about the nature of foundational certainties: they are pre-rational in the sense that they precede and enable rational discourse rather than emerging from it. Hinges are not conclusions we reach through reasoning but lived realities that make reasoning possible. Similarly, mathematical axioms are not theorems we prove but starting points we adopt to make proof possible.

There is an important difference between these domains. Hinges emerge from contingent practices embedded in particular forms of life, while mathematical axioms are selected through systematic considerations within formal contexts. Hinges reflect the biological and cultural circumstances of human existence, whereas axioms reflect choices made for their mathematical power and elegance. If anything, this difference makes the parallel more compelling by demonstrating its scope: if even the most rigorous formal disciplines require unjustified starting points, the necessity of such foundations in everyday knowledge becomes even more apparent.

This cross-domain similarity reveals what appears to be a universal structural requirement. Systems of thought, whether formal mathematical theories or practical epistemic frameworks, cannot achieve complete self-justification. They require external elements that are not justified within the system but make systematic inquiry within that framework possible. Rather than representing failures or limitations, these unjustified foundations function as enabling conditions that make coherent thought and practice possible.

Recognizing this structural necessity transforms how we understand the relationship between certainty and knowledge. Instead of viewing unjustified elements as epistemological problems to be solved, we can understand them as necessary features that allow knowledge systems to function. Both mathematical proof and everyday understanding depend on foundations that lie beyond their internal capacity for justification, yet this dependence enables rather than undermines their respective forms of systematic inquiry.


Conclusion

I have argued for a fundamental parallel between Wittgenstein's hinges and Gödel's incompleteness results: both demonstrate that systematic thought requires ungrounded foundations. By examining how epistemic and mathematical systems share this structural feature, we gain insight into the nature of foundational certainties across domains of human understanding.

The parallel between these seemingly distinct philosophical insights suggests that the limits of internal justification are not accidental features of particular systems but necessary conditions for systematic thought. Recognizing this gives us a more realistic picture of how knowledge functions, not through endless chains of justification reaching some ultimate ground, but through practices and formal systems that rest on foundations lying beyond their internal scope.

Rather than treating these limits as problems in need of a cure, we should take them as structural conditions of inquiry. Wittgenstein’s hinges anchor our epistemic practices in the lived background of a form of life; in mathematics, axiomatic choices provide the starting points of a theory. Gödel’s incompleteness results mark the corresponding boundary on internal vindication: even with the axioms fixed, a system strong enough for arithmetic has statements it cannot settle and cannot, from within itself, prove its own consistency. Both lessons show that the demand for a completely self-grounding system is not merely difficult but misconceived.

I believe this perspective has broader implications for understanding certainty and knowledge. It suggests that the interplay between grounded and ungrounded elements is not a flaw in human reasoning, but a fundamental feature of how systematic understanding must be structured. By recognizing this necessity, we can develop more nuanced approaches to foundational questions in epistemology, philosophy of mathematics, and potentially other domains where the relationship between systematic inquiry and its enabling conditions remains philosophically significant.

I have argued that this parallel is more metaphorical than substantive, because the two concepts operate in fundamentally different domains and address different kinds of problems. To claim a direct parallel between the mechanics of hinges and incompleteness is to make a category error. There is only a broad formal similarity between the two. Gödel saw his results not as a reason to abandon formalism but as a guide to discovering new, intuitive axioms from set theory that could extend our mathematical knowledge. He was a mathematical Platonist who believed we had access to mathematical truth beyond formal systems. For Wittgenstein, the problem of skepticism is dissolved, not solved. The response is to stop looking for a philosophical foundation and recognize the foundation in our ordinary practices.

Thank you for the response. I am not claiming that hinges and incompleteness are the same thing; I am arguing that they share a structural feature, a limit on internal vindication, that clarifies why both epistemic practice and formal mathematics proceed as they do. By “foundational,” I do not mean an inferential base that justifies the rest; I mean constitutive certainties that enable assessment and inquiry without themselves being earned by inference.

On the charge of “mere metaphor” or category error, my claim is second-order. Hinges are arational certainties that do not get their warrant from the very inferences they enable; they are part of the background that makes asking for reasons possible. Gödel’s results show that any consistent, effectively axiomatized system strong enough for arithmetic contains arithmetical truths it cannot prove, and cannot, from within itself, prove its own consistency. In both domains, there is a principled limit on what counts as from-within justification, that is the level at which I am drawing the parallel.

Gödel’s own Platonism is not essential to this point. Whether one seeks new axioms on intuitive grounds or not, incompleteness and the second theorem still mark the same internal limit. Extending a theory yields only relative vindication, inside the stronger framework undecidable truths reappear, and consistency still lacks a proof from within.

On Wittgenstein and skepticism, I agree that the problem is dissolved rather than solved. That is exactly why calling hinges “foundational” in a non-traditional sense matters, they are enabling conditions rooted in our form of life, not premises that do evidential work. The analogy respects this, it does not revive a search for ultimate grounds, it explains why the demand for a self-grounding system misfires.

There are important disanalogies, and I acknowledge them. Gödel sentences are ordinary propositions with determinate truth conditions, many basic hinges are enacted and often non-propositional. Mathematics is deliberately revisable and pluralistic; hinge certainties are far more stubborn and pre-theoretical. These differences do not touch the structural point. My thesis is modest and substantive; both domains exhibit a limit on internal justification, and seeing that parallel helps explain why the quest for a completely self-grounding system is not merely difficult, it is misconceived.

I transferred this post to epistemology, removing the NDE connection.

Part 2 of my book (a subsection):
Chapter 6: Epistemology and the Nature of Knowledge—A Deeper Dive

We often talk as if knowing were simple. I say I know my car is in the driveway, I know my closest friend’s name, I know the sun will rise tomorrow. Such claims feel immovable in ordinary life, and the confidence that accompanies them belongs to how these judgments function for us. Yet, when we press the matter, when we ask what gives that assurance its footing, we find that certainty is not a free-standing monument but part of a wider practice in which reasons, entitlements, and background certainties cooperate. The appearance of simplicity is instructive: it invites us to pause, examine the ground under our feet, and say what must already stand fast for talk of reasons, proof, and mistake to make sense at all.

The same tension frames NDE reports. A patient describes vivid perceptions while clinically near death—voices, instruments, exchanges among staff—and later offers a detailed account that seems to match the room and the timeline. The narrative arrives with conviction, sometimes with life-altering force and moral seriousness. But conviction alone does not settle what we are entitled to say we know, nor does it show how such reports fit the language-games of evidence. Our task is to sort conviction from warranted belief, and warranted belief from truth, without ignoring the human weight of these experiences or the public criteria by which claims are assessed.

In Chapter 2 I set out a four-condition account of knowledge that I will use here, call it JTB+U. Knowledge requires the truth of the proposition, the believer’s commitment to it, publicly assessable justification, and a further condition: conceptual understanding. Without that competence, words misfire, and what looks like a belief becomes a misuse of grammar rather than a contentful claim. With JTB+U in view, we can approach testimony with standards that respect ordinary practice while guarding against lucky alignment. In what follows, I treat justification as practice-indexed: reasons count within our language-games, the ordinary practices that supply public criteria for correct use (see Glossary: “Language-games”).

1. Truth — accords with how things are in reality; reality makes it true, not our confidence.
2. Belief — the subject takes the claim to be true, not merely recites the sentence or entertains it as a hypothesis.
3. Public Justification — the belief is supported by reasons others can in principle inspect, check, and contest; the support is not private.
4. Conceptual Understanding — the subject competently grasps the concepts at issue and can use the relevant terms correctly within the practice. Mastery shows in application: recognizing what counts as a correct move, spotting misuse, and explaining the ordinary tests. This is not a matter of private introspection but of publicly trainable rule-following within our language-games (see Glossary: “Rule-following,” “Language-games”).

The tripartite model reaches back to Plato’s Theaetetus and has endured because it captures something right about knowledge: true belief is not yet knowledge unless it is properly grounded. At the same time, lived inquiry is messier than tidy definitions suggest. “Justification” can become an empty placeholder if we detach it from the practices that supply criteria, error-signals, and standards of success. That detachment is what the “+U” is designed to prevent.

JTB, then, is a helpful starting point, not a final resting place. We sharpen it by situating reasons in use—within specific language-games—by marking the public criteria that govern correct application, and by acknowledging the hinge background that makes justificatory moves possible at all. With JTB+U in view, we can now state how justification works in practice and why that shift dissolves much of the apparent puzzle about luck and knowledge.

Enter Wittgenstein. He shifts meaning from inner pictures to use and relocates philosophical grip in our public, rule-governed activities. In On Certainty, he brings into view hinge propositions: arational certainties that are not hypotheses to test or theses to prove, but the conditions that let testing and proving count as such. We do not justify them; they stand fast for us, and because they do, reasons can be weighed. This vantage also clarifies the grammar of “know,” separating the epistemic use—answerable to criteria—from the convictional use that simply voices assurance. Set within this frame, JTB gains depth; adding conceptual understanding makes it a tool situated inside the practices it is meant to illuminate.

In the notes collected as On Certainty, Wittgenstein traces the limits of doubt and shows why a wholesale challenge to the background ends the very language-game of giving and asking for reasons. Some certainties lie in the river-bed, shifting slowly if at all; some are cultural-historical or personal-practical; still others are embodied and prelinguistic, displayed in how we move through a familiar room without inner consultation. These layers of bedrock make inquiry possible. They are not theses to defend; they are what allows defense and criticism to be recognizable practices. Acknowledging this bedrock does not canonize it; it clarifies the conditions under which revision has sense.

Before drawing a method from these insights, a brief orienting note about testimony’s place in the framework is in order.

Testimony is both a primary route to justification and, at a higher level, a proving ground for method. Because it is social, it depends on public criteria: access to the facts, competence in the relevant domain, sincerity, independence of sources, convergence over time, and resilience under attempted disconfirmation. Throughout this chapter, I will treat testimony, logic (inductive & deductive), sensory experience, linguistic training, and pure logic as principal routes rather than an exhaustive catalog. The ordering is fixed for clarity, not to signal rank. Testimonial claims will serve as a running case, precisely because they are rich, contested, and guided by public standards while remaining open to defeat by further evidence.

With JTB+U in view, and with hinges and testimony on the table, the task now is to lay out a method for evaluating knowledge claims in practice. The aim is modest and disciplined: identify the route, check the grammar of the claim, scan for hinge background, apply route-specific criteria, and screen for defeaters. Along the way, we will distinguish the epistemic use of “I know,” which is answerable to criteria, from the convictional use that merely voices assurance.


I certainly wouldn't propose that Wittgenstein would agree with everything I'm proposing. I'm merely extending what I think follows from Wittgenstein.

More on JTB+U with a twist

I have always been skeptical of Gettier problems, even back when I subscribed to the classical Justified True Belief (JTB) model of knowledge. To me, those examples never quite landed as genuine counterexamples; they seemed more like confusions in how we apply the concept of justification. In the standard Gettier case, like the one where Smith believes "Jones owns a Ford or Brown is in Barcelona" based on misleading evidence about Jones, the belief ends up true by accident via Brown. It's true, believed, and apparently justified—but it doesn't feel like knowledge. Critics say this breaks JTB, demanding fixes like no-false-lemmas or tracking conditions. But I saw it differently: Smith isn't truly justified; he's just thinking he is, relying on premises that don't hold up under scrutiny.

This intuition fits seamlessly into my JTB+U framework, which extends JTB with a Wittgensteinian twist. Knowledge still requires truth (the proposition matches reality), belief (genuine conviction, not mere recitation), and justification (supported by publicly assessable reasons via paths like testimony or logic). But we add Conceptual Understanding (+U): competent grasp of the key terms, demonstrated through correct use in the relevant language-game. Without this, claims misfire as grammatical errors, not valid epistemic moves.

In Gettier scenarios, +U reveals the flaw: the subject misapplies "justification," treating lucky or false-based reasons as a competent warrant. Smith's inference conflates private seeming (convictional assurance) with public criteria—his reasons are defeasible and hinge on a mismatch with reality. Hinge propositions, those arational certainties from Wittgenstein's On Certainty that "stand fast" (like "Evidence should track truth without coincidence"), ground genuine justification. Gettier cases dissolve therapeutically: they're not failures of JTB but calls to clarify usage in practice. We don't need to redefine knowledge; we need to see that "thinking one is justified" isn't the same as being justified in the shared stream of life.

This approach honors Wittgenstein's insight that philosophical puzzles often stem from misusing language. It keeps evaluation pragmatic: warrant emerges from public reasons and competent grasp, respecting conviction's human weight without equating it to knowledge. In the end, Gettier cases, rooted in misunderstandings of justification, underscore the value of JTB+U: knowledge as a practice in our forms of life, where genuine warrant leaves no space for luck.

While I believe JTB+U offers a fresh way forward in epistemology, blending classical JTB with Wittgenstein's later ideas on hinges and language-games, I hesitate to call it entirely new; philosophy builds on what came before, after all. It's more an extension or refinement, with some original touches like the layered hinges and the Gödel parallel, but grounded firmly in existing traditions. If it sparks clearer thinking, that's enough for me.

Continuing remarks on JTB+U

I begin where our practices begin. Before I argue for anything, I stand on what already stands fast: there is a shared world, words keep their uses from one moment to the next, memory and instruments ordinarily work, and other people are real partners in inquiry. I do not prove these each time I make a claim; I rely on them so that giving and asking for reasons can even get started. I call these fixed points hinges. They are not conclusions; they are the bedrock on which conclusions are drawn.

This starting floor matters because the old problems of regress and circularity never go away. If every reason needed a further reason, I would never begin; if I tried to justify the starting floor with the very tools it enables, I would move in a circle. Hinges stop both temptations. They are not secret premises and not dogmas; they are the background of our forms of life. They can shift when our ways of checking change, but within a given practice, they are the background that lets reasons count.

With that in view, I can say what I mean by knowing. To know is to accept something as true, to be able to give reasons that others can check, and to understand the claim well enough to use it correctly and to see where it does not apply. The public side is essential: justification is not a private feeling; it is an earned standing inside shared procedures. In my view, JTB is further strengthened by grounding it in this background, rather than weakened by its dependence on what stands fast.

The word “know” itself does two jobs, and conflating them generates confusion. Sometimes “I know” functions as an expression of conviction, as in “I know this is my hand.” No one expects evidence there; it points to the floor we act from. At other times, “I know” signals epistemic standing, where doubt makes sense and a route of checking is available, as in “I know the train leaves at 6:18,” backed by a timetable and ordinary procedures. My model keeps these uses apart: the first marks hinge-level certainty, the second belongs to justification.

Public justification runs along five familiar routes, none sovereign on its own: testimony, logic in both inductive and deductive reasoning, sensory experience, linguistic training, and pure logic understood as formal structure only, for example “X or not X.” Different questions call for different mixes, but the rule of thumb is simple: give the kind of reason a competent other could in principle verify from where they stand.

To keep the routes honest, I rely on three guardrails. First, No-False-Grounds: do not build on a mistake, so check the provenance of what you take for granted in the case at hand. Second, practice safety: use methods that fit the practice, so chemistry is not settled by a poll and character is not read off a voltmeter. Third, defeater screening: actively look for counter-evidence and better explanations that would undercut the claim. These do not replace reasons; they discipline how reasons are gathered, weighed, and held.

Understanding the “U” in JTB+U is not an ornament. It shows in competent use: the ability to extend a concept to new instances, to draw the inferences that go with it, and to recognize its limits without special prompting. Someone who repeats a medical note yet cannot tell a pulse from an oxygen reading does not, in the relevant sense, know. Understanding ties reasons to the grammar of the claim within the practice.

Taken together, the picture is spare. Hinges give us a place to stand, so regress and circularity do not paralyze inquiry. Within that space, knowledge is true belief with reasons others can check, further strengthened by grounding it in what stands fast. The five routes say what counts as a reason here, the three guardrails keep the routes from drifting, and the two uses of “know” keep our language clear. The aim is not a clever definition; it is a workable method for telling knowledge from its near-neighbors in ordinary cases and in the cases that matter most.

JTB+U

I start by fixing the background, and the chess analogy helps: you do not prove the board, pieces, or rules before you move; you stand on them so that a move can be a move at all. Inquiry works the same way. I rely on a shared world, on words keeping their uses from moment to moment, on memory and instruments ordinarily working, on other minds as partners in checking. These are fixed-point hinges. They are not conclusions we reach; they are what let giving and asking for reasons get started.

This starting floor matters because the old problems of regress and circularity never go away. If every reason needed a further reason, I would never begin; if I tried to justify the starting floor with the very tools it enables, I would move in a circle. Hinges stop both temptations. They are not secret premises and not dogmas; they are the background of our forms of life. They can shift when our ways of checking change, but within a given practice, they are the background that lets reasons count.

The analogy also marks the limits of doubt. In chess you doubt a move, not the existence of the board mid-game; in inquiry you doubt a reading, an inference, a report, not the bare possibility of language working while you are using it to doubt. Skepticism belongs inside the game, where there are procedures for checking. That is the sense in which hinges preempt the regress: they do not win an argument by force; they make argument possible.

Hinges are not chosen by whim and not certified by theory. We inherit them in our training and reveal them in what we count as a check. Over time, whole practices can change, new instruments, new techniques, new standards, and with them, some hinges may move. But the movement is slow and public, like learning a variant of the game rather than making a special move. Day to day, the hinges stand fast so that reasons can be given, tested, and corrected.

With this in view, the next step is straightforward: when I say “know,” I mean a true belief, backed by reasons a competent other could in principle check, held with enough understanding to use the claim correctly and see where it does not apply. The hinge background does not replace those reasons; it frames them. In my view, JTB is further strengthened by grounding it in what stands fast.
