Vagueness: 'I know'

Shawn February 10, 2020 at 19:22 9125 views 126 comments
When a person says, "I know", what do they really mean?

It seems inherent, that we assume that the other person "knows"; but, this is prone even to doubt and vagueness about using that phrase.

Therefore, how can we qualify the statement or word-phrase, "I know"?

Is this possible, and has already been implemented in our childhood and adolescent life that is education?

Or stated, otherwise, how does one set up a schema to decrease the vagueness of the word phrase "I know"?

What ambiguity? If someone says he knows, maybe he does, maybe he doesn't, but what is ambiguous about the claim itself?


Sorry, I got the whole thread wrong. I meant to say, how does one eliminate the vagueness of that phrase?

"I know..," doesn't do it for me, because I find zero ambiguity in it. Whether it's true or not a whole other topic.


Whell, that's part of the topic-subject hereabouts.

Is "I know..." truth-apt or not?
Qwex February 10, 2020 at 19:57 #381126
I know thinking as the action side of thought.

When someone thinks, they use knowledge and environment. When someone says I know they refer to wisdom or a phenomenon.

Is this purely an action? Knowing? Referring to your wisdom or phenomena directly, that process?

You may just as well not think of wisdom as a pattern of knowledge but instead as a shell of knowledge.

You can know in the short and long terms.

The problem you refer to lies within language itself. Words inherently have a range of meanings. If I have an image in my mind that I am trying to communicate there are only a limited number of words that I can choose from (and even selecting an appropriate word is a complex process) and the final communication can only be a poor representation of the picture in my mind. If you go for too much rigour in the communication one does so with an associated lack of accuracy.
Shawn February 10, 2020 at 20:02 #381132
Quoting tim wood
As it stands, its meaning is set by convention. And as it stands, it seems to me, the truth of it is verified by evidence wrt some criteria, wrt a degree of satisfaction under those criteria. E.g., "I weigh 196 pounds," is arguably never, ever exactly true. .


OK, so you're already assuming some pragmatic account of shared meaning, correct?

Thus ambiguity is an artifact of the language actually used, and as such calls for correction, not refinement.


This doesn't make much sense to me. It seems that refinement comes first, and then a correction can ensue? But, some degree of ambiguity is always present.

Could you give an example of a kind of qualification that might make you think an assertion was less vague?

It seems to me that 'I know' is a clear statement, though obviously not a complete one. The person may or may not be correct, but we get what they are claiming. They have excellent grounds to believe that X is the case. It fits whatever rigor (if any) their epistemology has.

We can't come up with a way to qualify the statement, since it would need different more complete explanations for the different users of that phrase. Because different people, even within the same paradigm, have different criteria and different degrees of rigor.

This is language we are talking about. We cannot make individual phrases, in general, be 100% clear. And if we did, they would be so specfic as to be less useful.

A scientific journal can have specific criteria for what it will publish in a sense as well grounded conclusions.

But words and phrases are meant for all of us to use to communicate in a vast array of contexts.

I am with Reply to tim wood that the word is clear. One can use other words if one wants to be more specific about one's criteria, the process of deciding that you know, rather than, say 'believe' or 'think' X is the case.

Every word you would use in your clarification of 'I know' could then be criticized as vague, since one could always go into more detail. And any clarification of the phrase 'I know' would either be just as vague or not as generally useful.

Right, and that's exactly why the phrase is ambiguous. We don't know who weighed you, how they weighed you, when they weighed you, and so the phrase is ambiguous. We cannot pinpoint the meaning of it. What does it mean for a human being, whose weight is changing by the moment, to say "I weigh …" and quote a static quantity? As there is clearly no correct way to interpret this statement, it is a perfect example of ambiguity.

You don't know what "know" means? Have you looked it up? Have you got anything to say about how it has been treated by philosophers?

In what way is its use vague, as you keep on saying it is, with no explanation? You have not described the problem with "I know" or how it is vague. It's your OP that is vague. There is no clear question, and what there is doesn't make much sense.

Not at all. When someone says they know, we don't just assume they do, unless it seems fairly uncontroversial and we don't have reason to doubt it, in which case we might give them the benefit of the doubt. But you don't give any context anyway; there are different ways of using the word.

That's what they mean and it is clear.

What does IT mean if they say it?

It means they have no doubt X is the case.

Is X the case? Maybe maybe not.

But that has nothing to do with the meaning. It seems like you are conflating the truth value of the that clause with the meaning of the sentence. The meaning of the sentence is clear. Whether the that clause in and of itself is true is another matter.

I know that Idaho is the largest state.

The person is telling us that they have no doubt it is the case that Idaho is.......

The truth value of the that clause here is false. But that does not affect the meaning of 'know' in the least. He means that it is true and he has no doubt about it.

Another way to describe this is you are equivocating on the word means.

Means as in what is the person conveying.
And then the other means as in what are the consequences of hearing this assertion. That we accept their assertion about Idaho? or not?

Two different types of 'means'.

There is nothing unclear about the meaning of know.

I've walked passed and registered a tree, calling it X.

My friend and I discuss if there is any matter as to why we can breathe.

I stop, I say "Oh, I know" in reference to an off-hand theory I had about X.

What is vague about knowing?

I have a memory of X, it also is a pattern; when asked some questions I am a knowledge man, through the pattern of X, or X directly (if I was asked did I pass leafs on a trunk).

What's vague is my knowledge of X, not being 100%.

Can we spake a resolute "I know"? I'll let you decide.

As for the matter of this topic, I don't think 1 + 1 = 2 means "I know it = 2" is vague, I don't think X is vague. I think it's a whole different topic. We're discussing whether theories can ever be complete.

That's a long phrase to solve a problem I don't think I experience. In what contexts are you thinking we should substitute something like that? And if we really think we KNOW, that would not be conveying what we mean. I am not forced to take them at their word, but it does give me a clear message about they own assessment of their assertion. If someone I respect a lot says 'I know X to be the case' that is taken by me in one way, from a stranger another and so on. But it gives me a clear mess about that person's sense of what they are conveying. WE all know that people can think they know when in fact they don't have good ground for it. I don't feel compelled to accept what they say, but it does provide extra information. If someone goes out of their way to say 'to the best of my knowledge' I will think they are less certain or that's how they want to couch all their assertions. I won't know which until I get to know them. So, it's still not clear. And if it is someone I know, then I have a good sense of their thoroughness. I see no loss in the current common use of 'I know'. If I was naive and felt compelled or their were rules that I was compelled to accept any assertion starting that way, well, that would be a problem. But that's not the world I live in. If they say 'I think...' that conveys something else. And people can manage to convey their utter certainty and that one would be stupid to disagree with them when using 'to the best of my knowledge'. Just imagine that said in a condescending way. I don't think people should start using this long phrase that in itself might be incorrect. Perhaps they have actually seen counterexamples to what they are asserting so it isn't to the best of their knowledge, but they stubbornly believe. Any formulation is going to still be problematic if we conflate what the person means and the truth value of what they are saying.

Invisibilis February 11, 2020 at 23:06 #381512
Reply to Wallows In regards to OP. Let's see if "I know" what you meant by your questions.

Some people say "I know" in a vague way, especially when you already have not clarified what there is to be known. They say quite flippantly "I know", but later evidence shows that they did not know. In this case,fear of being judged as naive, or ignorant, urges the person to shutdown any further dialogue that might reveal what they fear. Though they cannot see it, they are keeping themselves in ignorance by ignoring what they don't know.

To decrease their vagueness about "I know" is to add a qualifier; as in, "I know that . . , or "I know if ...."
If the person cannot add a qualifier, then their "I know' is just a reaction from a fear of judgement.

The one explaining may know that the other does not know, and may actually say "Hear me out"...to create a pause in the listener.

Most people who say "I know" when they don't, are young people who still carry falsehoods such as shame (believing they are a mistake), usually introduced by their piers.

Reply to Wallows

We know some statement when at the least we believe it, it fits in with our other beliefs, and when it is true.

The "fits in with other beliefs" is a first approximation for a justification. Something stronger is needed, but material implication will not do.

Discard Gettier. The definition is not hard-and-fast.

It does not make sense to ask if we know X to be true; that's exactly the same as asking if we know X. The "we only know it if it is true" bit is only there because we can't know things that are false.

If you cannot provide a justification, that is, if you cannot provide other beliefs with which a given statement coheres, then you cannot be said to know it.

If the consequent Q is true, then so is the justification P > Q. If ravens are black, then grass is green; hence, that grass is green justifies that ravens are black.

So that will not do.

You seem to be looking for something that we can be certain of, perhaps as a way of founding an epistemology.

But that seems to me to show a misunderstanding about belief.

Certainty is a type of belief - a belief that is beyond doubt. But of course, one can believe anything one wants - even things that are not true. Hence, one can be certain about anything one wants, even stuff that is not true.

But one cannot know stuff that is not true.

Compare:
"He is certain there is a Santa, but of course that's not true"

with

"He knows there is a Santa, but of course that's not true".

Seems that both words are used the same way, and therefore mean the same thing (if meaning is just use and all that)

Now, are we talking about the state of someone's belief, or the state-of-affairs that the belief is about? Could it be possible that a person could be confused about both? Is it possible to be confused about whether or not you actually know, or are certain of anything?

If we associate truth with knowledge then people misuse the terms a lot. They claim to know when they don't. In order to know that someone actually knows would require that a second party know, but then how would we know that they know if it possible to be wrong when claiming that one knows? When, how, and who knows when some belief is true?

If we just equated knowledge with JTB, and severed knowledge from truth, then we wouldn't have the problem of people using the term incorrectly. Knowledge doesn't require truth, only justification. Then people only misuse the term when they don't have any justification for what they are claiming they know.

Another thing that we need to think about is different kinds of knowledge. No, I'm not talking about knowing how and knowing that. We've already shown that they are the same. What I'm talking about is information made by humans as opposed to natural information. Take the information that Donald Trump is president and the information that the Sun will die in 5 billion years. The former is information, or meaning, created by humans. The latter isn't. The truth in the latter lies in the actual state of affairs that is the Sun in 5 billion years while the truth of the former lies in the minds of humans as something that humans arbitrarily made up. Humans created the truth of who is president at any particular moment, but nature is the one that created the conditions, or the truth, of the Sun in 5 billion years. It is much easier to know the truth of who is the president of the U.S. than it is to know when the Sun will die.

When a person says, "I know", what do they really mean?

It seems inherent, that we assume that the other person "knows"; but, this is prone even to doubt and vagueness about using that phrase.

Therefore, how can we qualify the statement or word-phrase, "I know"?

Is this possible, and has already been implemented in our childhood and adolescent life that is education?

Or stated, otherwise, how does one set up a schema to decrease the vagueness of the word phrase "I know"?


"be as wise a serpent and as gentle as a dove for he sends us out among wolves" (paraphrased slightly)

There are one to one (a type of linear), linear, exponential, inverse exponential, logarithmic relationships. There are also coefficients and constants that altar a graphical representation of a relationship. When someone says they see a exponential or inverse exponential relationship between an apple and an orange, they are somewhat saying there is a loose relationship. You can actually draw a relationship between any concept and any object or physical object. The relationship might be loose or strong.

My point is stretching the truth and lying are two different things. I someone says "I Know" , it puts what they are saying on a spectrum, and they might loosely know or have faith that you know, or they may have a very strong concept of what you are saying.

This is why I don't expect much of a response when I point out the failure of your arguments.

So the above two sentences are not using "certain" and "knows" the same way? What do you mean by "use" if not that the words are occupying the same space among the same string of scribbles and in the same context?

Quoting Banno
The problem is not that they are misusing the word - of course the word might be used in that way. The problem is that they fail to take into account an important distinction. In this case, Harry ignores the distinction between believing, which can be either true or false, and knowing, which by definition must be true.

And like I already said in the post your cherry-picked and failed to respond to: How can we be certain that what we know is the truth? How does anyone know that some claim is the truth? We make claims all the time about our knowledge without having any proof that what we claim is true. We only have justification for our beliefs that qualify as knowledge. Without justification, it is simply a belief. How do we determine what qualifies as proper justification? - Logic.

Your qualification of truth for knowledge is unattainable, therefore "know" would could never be used correctly and would therefore be a useless word.

It seems to me that "certain" would be a stronger assertion of truth that knowledge would be. Take the Merriam-Webster definition of "certain" as an example:

Quoting Merriam-Webster
known or proved to be true : INDISPUTABLE
it is certain that we exist


So, "knowing" would be more like I said: a justified belief, whereas "certainty" is something that is often unattainable (mostly when it comes to external truths - truths that humans didn't create themselves - like how and why did the universe come to exist), hence the existence of philosophy and skepticism.

What I get from both Merriam-Webster's definition and the article you provided is that IF certainty and knowledge are not the same thing, then certainty is the carrier of truth, not knowledge. Certainty has a stronger quality of truth than knowledge. So you can't say that if "you know it then it is true" if you are implying that "certainty" and "knowledge" are distinct AND that certainty has a stronger connection with truth than knowledge does, according to the definition and the article. If you are certain, then it is true. If you know it, then it is justified yet you can still have doubts, or be open-minded to alternative possibilities that haven't been provided yet. True wisdom is often equated to knowing that you know nothing.

Saying “I know” means “I have information from a reliable source and that information is actually true.

I can say “I know” but later find out that the information wasn’t true, so in fact I didn’t know. I was incorrect when I said I know.

No one could say “He knows there is a Santa, but in fact there isn’t.” If the speaker doesn’t believe that the person referred to is right, he wouldn’t use “know” about the claim.

The source of information is also important. Suppose someone told me that Manchester United won the match and I pass the information on saying “I know United won”. Later it turned out that my informant had had no idea whether United won or lost, but accidentally United had in fact won. When I said “I know United won” I was therefore incorrect even though what I thought I knew was true.

We can of course make the claim that we can’t really be sure if anything is the truth and even if I was present at the game and witnessed United’s victory, I can’t be a hundred percent certain that I can believe my eyes. Well, that’s a philosophical point. For our daily life our normal criteria for truth are sufficient.

Reply to Harry Hindu Certainty is a measure of your conviction that you are right. You might be an idiot. Knowledge is presumably a rigorously arrived at belief. There were some criteria involved. Different people have different criteria, but pretty much everyone uses I know when they are more certain based on certain criteria that have been met, criteria that have not been when they say 'I think...' or 'My guess is...'

What is considered knowledge may turn out not to be true. Hopefully one's criteria for what gets called knowledge, by you, make it a stronger set of beliefs than what you simply think is or might be the case.

When people argue about epistemology they are arguing about the criteria.

Certainty is a kind of quale, it may have nothing to do with any useful criteria, even your own. It might be based, for example, on denied feelings of terror that you might be wrong about the issue. That can actually increase one's certainty. But it's not a criterion for being classed as knowledge. That would be something like and scientists in Berlin had the same results with an even larger sample. Or I saw the puma, not just the footprints, and it was not a guy in a puma outfit. I am not one of the people who heard the story, I was there. (note, that would be a strong criterion for the speaker, but not necessarily at all for others listening to his story)

The truth of it? I doubt you mean that. But what does that leave? If I say I weigh 196 pounds, that's both vague and precise, depending on how accurate one wants to be. But the claim itself, that I weigh 196 pounds, with respect to appropriate criteria is not at all ambiguous. I'm thinking you understand my question.


For someone who is such a stickler about proper word usage, you seem to have absolutely no idea about the proper usage of "precise" and "accurate".

Precision is a measure of how much information is being conveyed. Accuracy is a measure of how closely the information conveyed corresponds to reality.

E.g., if I were to say that I weigh between 0 and 1,000 lbs that would not be very precise, but would be perfectly accurate. On the other hand, if I were to say that I weigh 27.13856182952 lbs, that would be a very precise answer, albeit extremely inaccurate.

The claim that you weigh 196 lbs is also, in fact, ambiguous since you have not indicated the degree of precision that you wish to convey. Though, assuming some informal conventions, we might accurately infer that you were specifying your weight to the nearest pound. If you had said that you weigh 200 lbs, that inference is less likely to be correct, since you might reasonably be rounding to the nearest 10 lbs, or some such, but we have really no way of knowing unless you tell us.

In any case, this is just basic high school science and to not be aware of it, is shockingly stupid and ignorant.

Reply to Harry HinduI am pretty sure we all know people who are certain on almost no grounds at all. But the main point is that certainty is a term referring to a feeling, a quale.

Sometimes we can even admit this. I am certain she is cheating on me but I have no evidence. I trust my gut.

Of course the two idea overlap. They deal with different things. And presumably we tend to be more certain about what we consider knowledge. But they do not have to be connected. Further they are focused on two different things: one on a kind of emotional sense, the other on protocols.

It seems like you're saying that one can be certain without any reasons or evidence for what they are certain about. That isn't how I or anyone else uses the term, "certainty". Now that I know that is how you are using the term, then I am going to expect you to provide evidence because now I can't be certain that what you are "certain" of is true. To be certain means that you put forth some mental effort to parse some bit of information for logical and empirical consistency before you say that you are certain of something. To say that you "know" is to say that you have good evidence, or justification for something but there could possibly be other explanations that you aren't aware of yet. It is a way of saying that you have a set of rules for explaining or interpreting something and those rules are amendable.

'Reasons' they obviously have. They need it to be true, they heard from their best friend, it makes sense to them, they read it in a scientific journal, they saw it happen, they think being uncertain is weak...and so on. They are saying they have no doubt. They may have doubt. They may know deep down that they are not really certain. They may have good grounds. They may not. They make be the kind of person who trusts their intuition (and shouldn't). Some people are just certain in general. Some are certain when they have good evidence. It varies subject to subject. When someone is certain this does not indicate anything about epistemology, theirs or in general. It's a mental state or a measure of one. It measure a lack of doubt or the presentation of that. Of course each person will likely think that their certainty is based on good reasons, but that is not what they are saying when they use the term.

No, that's not what it means. It's a synonym for being sure. For many people to say they are certain they need to meet the criteria you put forward, and presumably you do this. But the humans I meet are certain for a wide range of reasons and often not for the reasons they put forward.

I more or less agree with your definintion of know. But it's good you brought up your objections. It does depend who is speaking and about whom. People say 'I know' for all sorts of reasons. People tend to categorize knowledge as opposed to opinion as some more rigorously arrived at subset of beliefs and opinions. JTB more or less. IOW they have a knowledge/opinion(belief) distinction. And they can see this, in a certain sense, clearly in relation to others. And all of us have encountered people who are certain of things that have not gone through any rigorous process, even whatever rigorous process that other person would say it should.

Certainty is a quale - which may or not be affected by rigorous epistemology
Knowledge is a sub-category of beliefs/opinions and we all mean that it is better arrived at than the rest of the beliefs/opinions. How it is arrived at and if we really followed some rigorous process in this case or any case is another story. But when people use 'I know' the reasons can be just like the partial list I have above for 'I am certain.'

Knowledge and certainty however are very distinct and have very distinct referents.

Why do we often find out after making the claim whether or not our knowledge was true or not? Maybe we were getting ahead of our selves and claim to possess knowledge when we didn't have proper justification. That may be the problem - that most people use "know" to casually - often meaning a belief or hypothesis rather than real knowledge. When someone claims to know something, is their knowledge evidence, or proof, that their claim is true? Is their claim that they have knowledge evidence, or proof, that they possess knowledge?

You're turning what something means into something it does in this question. If we know it, that means it is true, in most definitions of 'know'.

Though since even knowledge is revisable, if one is, say, a scientist, even then it may turn out not to be.

Excellent, Banno. You're more tin-headed than most but eventually make your way to seeing that I was correct all along.

Reply to Harry Hindu Yeah, Thing is, I'm making the same point I have been making for years.

If I claim to know, it can either be true or false, so the expression 'I know', is vague on that degree.

Knowledge, however, is not vague...

{{There's a difference between knowing and claiming to know; knowing is K, K-significant simulation aspect is KX.

If K, then KX - K = X. If -K, then KX - X = K. Simple code.}}

Knowledge is an accurate process.

If I actually know X then X - X = 0 is what I know. Whether or not you do or don't know is vague - but it's not vague if you [I]do or don't[/i].

I think knowledge is not a claim, but a effort. If I know without a claim it's a simple mental effort.

This thread doesnt contain what you've said for years - only what you've said recently, which is inconsistent.

Maybe that's the problem, Banno. You been saying the same thing for years, so you must think that there's nothing else for you to learn and that you know everything.
