What is true

Scribble January 18, 2019 at 05:09 11700 views 123 comments
Consider the postulate: The only tool we have available to provide support or not for the truth of anything is application of the scientific method.

Do any members know of any other tool or method that we have available to provide support or not for the truth of anything. Try anything: trees exist, Mary loves Jane, the World is flat, the World is round, thunder is the sound of Zeus, the Rainbow Serpent is a god creator … choose anything and find some method other than the scientific method to ‘prove’ its truth. I put ‘prove’ in quotes, because maybe nothing can be absolutely proven, so let’s say prove to a broad consensus of satisfaction. That is why I chose to say ‘provide support or not for the truth’.

Reply to Scribble Then why not make this general consensus business the method of establishing truth? Because either way your initial postulate is false on pain of vicious circularity. It fails its own dictum unless it relies on itself, which isn't gonna be very helpful.

Ok, but, apart from the truth or otherwise of the the scientific method, back to the question: is there another method. probably 'general consensus' was a red herring. Any guide to other methods?
MindForged January 18, 2019 at 05:52 #247336
I'd say observing a thing reliably and consistently being some way if perfectly fine way of establishing something to be true generally. That's not science, otherwise science would be too broad a category and no one would regard it so highly. I see, feel and hear this phone in my hand, so I'd say that's about as good evidence as required to reasonably assert that "My phone exists" is true.
Scribble January 18, 2019 at 06:45 #247339
That is close to the scientific method. If that process starts with postulating that something is true (a theory), and then observe in a reliable and consistent way whether 'the thing' appears to exist or behaves in the manner postulated, and no instance is found where the postulate is not satisfied, then that IS the scientific method.

In my opinion, the objective of science is the simulation of behaviour, with the aim of inventing efficient and understandable languages with which to communicate the body of results of simulation experiments, for purposes of engineering.

By the most pragmatic interpretation of that aim, any invented language and method of simulation suffices as a scientific method provided it achieves its goals of behavioural replication to the level of precision deemed necessary for a given engineering application.

Reply to tim wood Yes, true and truth are not the same; true is an adjective and truth is a noun. Otherwise they may be the same. E.g. It is true that I exist. The truth is that I exist.

Reply to sime The objective of science is far more than that. Science seeks to understand and describe nature, which would include behaviour and one tiny field of nature.

the scientific method.


Which scientific method?

Falsification? Coherence? Survival of the fittest paradigm? Research Programs? Anything Goes?

It's not exactly clear what the scientific method is.
Scribble January 19, 2019 at 05:58 #247682
Reply to Banno All those things might be part of the process of application of the scientific method, but there is one 'method.
The scientific method is: one begins with a theory or hypothesis, which might be preceded by research or other process, such as just a 'bright idea' or a guess. Then one would test the hypothesis, commonly by experiment, or by gathering data relevant to the hypothesis. This stage should be impartial. One should not be just looking for data to support the hypothesis, but data to test the hypothesis. One should especially search for data that disproves the hypothesis, since by that means one is likely to strengthen the conclusion if the conclusion is in support of the hypothesis. Tests should include statistical analysis of the results of experiments or data collection. One then comes to a conclusion about the validity (or truth if you like) of the hypothesis, or the probability that it is true. Note that I have not said 'prove', because that implies an absolute yes or no. In most cases for a hypothesis that is supported by this process there will remain that it might be disproved when new data comes to light in the future, which commonly occurs in scientific activity. Disproved, because usually one instance of a hypothesis being untrue would show absolutely that the hypothesis is not true, at least if it was hypothesised that it should hold in all circumstances.
Although this is called the 'scientific' method, I don't believe it should be applied only in cases where the hypothesis might be regarded as a 'scientific hypothesis', which really brings me back to my original question of whether any other process can be used to test whether something is true (or better, probably true) or are all other candidates just the scientific method in disguise.
Scribble January 19, 2019 at 06:11 #247684
Reply to emancipate The scientific method does not "accept' or not accept anything and the only 'requirement' is that one begins with something to test, usually referred to as a hypothesis. I don't understand some of your response, such as "This excess reality" and "the criteria of science", but I do say that the scientific method is specifically geared towards finding the truth. Its only purpose is to determine the truth of a hypothesis.

...but there is one 'method'.


Yours is a neat account of the mythical method scientists tell each other that they use. Please don't read that as being disparaging; it's the sort of thing a budding scientist needs in order to have an idea of what is going on.

But there are many other stories.

None of them will account for how I know I have a headache, how I know I am rather fond of wife, how I know what seven is nor how I know where I live.
Scribble January 19, 2019 at 07:03 #247688
Reply to Banno But they can. Put those in the form of hypotheses: I have a headache; I am fond of my wife; i know where I live (as for 'I know what seven is', you would first have to state what seven is, according to you). These then become hypotheses. Relevant data could be collected and experiments devised to test these hypotheses. The results could be analysed, and conclusions dawn, such as the probability of each being true.
That is the real method that scientists use, and others use as well, though others would not always recognise what they are using as the scientific method. All scientists, whether budding or experienced, use (or should use) this as the basis of all they do, not just 'to have an idea of what is going on'.

Reply to Banno Those two pieces of data are a start.

Per Wiki, the steps of the scientific method:

Define a question
Gather information and resources (observe)
Form an explanatory hypothesis
Test the hypothesis by performing an experiment and collecting data in a reproducible manner
Analyze the data
Interpret the data and draw conclusions that serve as a starting point for new hypothesis
Publish results
Retest (frequently done by other scientists)

Interesting response. As noted in my listing of the scientific method steps above, all of the data gathered in step 2 ("Gather information and resources (observe)") would be accepted without formal method. You'd just have the phenomenal state and accept it as true, making phenomenal states foundational.

Possibly the scientific method provides a basis for why we have these phenomenal states, but does not provide a basis to determine whether phenomenal states accurately reflect reality. That issue is within the purview of metaphysics, and just like that of morality, is not addressable through the scientific method.

Reply to Hanover As if defining a question can be done without knowledge, as if information and resources are not knowledge...

If I was being hardline about it, I would say that all knowledge comes exclusively from observation, and science as method is not in the business of accumulating knowledge but of organising it.
Hanover January 19, 2019 at 13:57 #247751
Reply to unenlightened Sure, if the scientific method begins with a question, you can step back and ask where that curiosity came from, which is obviously from some prior observation and I suppose some hard wired rationality, intuition, and maybe emotion. But the question isn't where the method came from, but it's what it is. Otherwise, you're left with saying that every primitive culture engages in the firsr step of the scientific method every time they observe something. I would think it's a major step forward to pose a question for testing, and that's when you've engaged in a real method.

That's all fine and dandy in theory, but then in practice how do you know when an hypothesis is untrue? You may say, if an observation doesn't match the hypothesis then the hypothesis is untrue or falsified, but how do you know if the observation doesn't match the hypothesis? You may say it's obvious whether it does or not, but how do you know whether the instruments of measurement you use work the way you believe them to work? How do you know there isn't some effect you haven't taken into account that is acting on what you are observing or on your instruments of measurement? In fact, you're never really sure whether your hypothesis in itself is untrue or not, that depends on a whole bunch of other hypotheses you make unconsciously when making an observation.

Scientists use the theory of general relativity. Some observations about galaxies do not match the theory. Is it because the theory is untrue, or because of something they haven't taken into account? They went with the second option, they believe there is something they don't see, which they call dark matter, that is acting on the galaxies they see. They tried to detect it in other ways, they devised some huge experiments, and they still haven't found it. Is it because this dark matter doesn't exist, or because it has properties that makes it undetectable to the experiments carried out up to now? In fact if we never detect it, we can never really be sure whether it's because it doesn't exist or because we haven't yet conducted an experiment that can detect it. The range of possibilities is infinite, we can never rule them all out. So we end up realizing that science doesn't deal with truth or even probabilities, if we're being honest we're never really sure about anything, we can't prove a theory is true and we can't prove it is false. The prize at the end of the scientific inquiry is not truth, it's just the ability to predict the future to some extent.

What's truth even? It's absolute certainty, something you can hold onto no matter what, but what fits that description? Scientific laws have a limited applicability, they're only laws as long as we blind ourselves to a whole bunch of observations and experiences that don't fit them. Maybe there is no such thing as absolute certainty. Maybe you're not just a passive being subjected to absolute laws, but a being that has the power to bring about change in the way you desire. The quest for truth seems like the quest of the individual who feels powerless and desperately needs to hang onto something to feel a bit safe.

Reply to tim wood agree in total, the history of the scientific method is a long line error assumed correct until superseded, This also may be its highest praise that when shown false it easily lets go of the false belief. As a fact finding process, for those things that can be identified as fact, or so near fact as to be accepted as such, it has proved to be useful.

Absolute truth is most probably unattainable. The scientific method along with logic are the best tools we have to make sense of our environment and utilize the knowledge to make our lives more confortable. Falsehood, on the other hand, can usually be proven (isn’t that what the scientific method is all about?) Ironically, isn’t the search for truth really the search for disproof?

How do I know it is true you have a headache? how do you make your truth, my truth?


That's epistemology. The supposition in the OP is that the only way to truth is by the scientific method.

There's lots going on here.

Truth and belief are different things. Something can be true, and believed; true, yet not believed; false yet believed; or false and not believed.

Then we have knowledge. Usually that's taken as true belief with a bit extra, a justification or some such.

It seems to me that nine-tenths of the epistemic errors on this forum come from failing to differentiate these well.

Your point about the difference between my knowing I have a headache, and your knowing I have a headache, is most important. Being true is something that statements do, and since belief and knowledge are about truth, they are also about statements. Statements are things we do with words, and hence essentially communal.

While it is an excellent rhetorical device, the line "how do you make your truth, my truth?" will not do. If something is true for you, but false for me, then either one of us has mis-stated what is going on, or one of us is wrong. There is no "my truth" and "your truth". Relativism cannot be made coherent.

While we might believe that someone is in pain by an application of the rigid scientific method @hanover quoted, there wold be something quite pathological about doing so. Picture a man with a protruding tibia, writhing in agony. What would one think of someone who said "first we must define the question: Is this man in pain?; then we gather information and resources: google 'fractured tibia'; then we form a hypothesis..." and so on. There would be something quite inhumane in the lack of empathy of this reaction.

It's more complex than that. One's own phenomenal state ought be checked against the phenomenal states of others; do they see what I see? And doing this is already interpreting that one sees.

Reply to tim wood I basically agree. The main change I would make is to clearly differentiate truth from belief. it's not what is true that changes over time, but what is believed. The Earth went around the sun before Galileo.

That is, I reject the notion that what is true is relative to the conceptual schema within which one works. And I would do this by pointing out that some explanations are just wrong.

We don't find truths with science unless you call measurement a truth. What science does is generate hypotheses to explain observation.and these are considered only provisional.

Also the scientific method is a derivative of the broader concept of rationality.

Are you not drawing a distinction between knowledge and certainty here? We don't use science to obtain certainty. A scientific experiment is based upon its analysis of observations. Our observations may or may not comport with reality, but what we're assessing is our observations and trying to figure out what brings them about.

I just think the counterexample you provide in this OP is of a different category and not really an attack on the proposition that all knowledge is obtainable through the scientific method.

...but on that basis alone by itself you do not take them as true, do you?


Well, yes. To believe ? is to think that ? is true. Recall Moore's performative contradiction: "I believe ?, but ? is not true".

The "on that basis alone" bit. Some things I believe, and there are reasons that I can provide for that belief. Other things, not so much. Our reasons for believing are many and varied, perhaps as many as there are beliefs. Certainly there are very few things that I believe because I followed some method to determine its truth.

Quoting tim wood
It seems to me you have two overlapping understandings of what true is. First, there are the things you are satisfied are true. Second, I infer that you suppose that there is intrinsic to the world a state of affairs that when expressed, that expression of that state of affairs must be true.


The things I am satisfied are true are my beliefs. That's not a type of truth, because obviously some of my beliefs are not true. I could work with the next bit if you remove "intrinsic to the world" - I've no idea what that means. Oh - "A state of affairs, when expressed" is a bit hairy too; states of affairs are already expresses. The world is always, already, interpreted (Davidson). So I guess we are left with "Some statements are true". Yep.

Quoting tim wood
But you operate (it seems to me) with a third: that your truth can stand as an expression of the intrinsic state of affairs of the world, and thus is universally true.


Well, it's not my truth, usually, so much as our truth. Again, I don't see what "intrinsic" does in that sentence , except confuse things; can there be an extrinsic state of affairs? Why do we need to draw attention to such a distinction here? And "Universally true"?True for everyone, or true as part of a universal quantification?

Basically, Tim, there's an extraordinary amount of overkill here. Have a read of my About page.

Are you not drawing a distinction between knowledge and certainty here?


Oh, yeah. There are plenty of things of which we are certain, but of which we ought not claim knowledge. This is because knowledge requires (on one common rendering) justification. "Here is a hand" and "I have a headache" do not require justification.

I can make sense of certainty as a sub-class of belief, not as a sub-class of truth. We are certain of stuff that we cannot doubt.

Quoting Hanover
just think the counterexample you provide in this OP is of a different category and not really an attack on the proposition that all knowledge is obtainable through the scientific method.


Well, if your position is that knowledge must be justified, then since that I have a headache has no justification beyond my having a headache, you might have a point.

Well, yes, it is commonly done. Each time you ask me to pas the salt, we check our agreement on there being salt. This conversation checks our agreement on how computers, internets and English work.

And our agreement overwhelms our disagreement. It's just that our disagreements are much more interesting. We spend little time agreeing that the "Q" is in the top left of the keyboard, because there is no disagreement there - unless you have a different keyboard, in which case it might be of interest.

Banno January 21, 2019 at 01:12 #248473
Reply to prothero It can be true that Prothero has a pain in his toe.

Are you asking is you cannot share this? no, because of course you could tell us that you have a pain in your toe.

Are you asking if it is something only you could believe, or know, or be certain of? Again, no, since we might believe, know or be certain that you have such a pain.

Are you pointing out that we might believe that you have a pain in your toe because you told us, while we might believe you have a toe because we can see it? Well, yes. That's not two sorts of truths, that's two sorts of justifications.

Keeping things clear seems again to me to dissolve the philosophical speculation.
Banno January 21, 2019 at 01:13 #248474
Reply to prothero Same goes if you are saying that you know about the pain first hand, while we know about it second or even third hand. THat's differences in the justification for our belief, not differences in truth.

Closed-openmindedness January 24, 2019 at 10:16 #249705
Hello, so it seems to me like the scientific method is to communicate shared experiences, observations, results, in order to explain collected data. It is true information only if results are recorded. It is truth if the results can be replicated every attempt at performing the experiment.
I really dont want to be the one to say that the truth is, none of us will ever know what is true or what is not true because even feelings can be deceiving. Limitations are not even true such as natural laws governing matter are being broken at the quantum level. I really want to think of another method for all of you and the only thing that comes to mind is learning. For example, as a child you are forced to obey parents or guardians and listen to what they say is true because their actions brought you to exist. They provide for you and seems to be true until you are able to actively think about what has been said or shown. Knowledge seems to im'prove' your chance for existence and that is our tool to find safety and comfort. Here are some truths I struggle with : you need to consume water or fluids to live, all mammals bleed, and all information can be disputed. Thank you.

I don't think you understand what I mean when I say contradiction. I'm not saying that there can't be paradoxes like cold and hot. What I'm saying is that something can't be cold and hot at the same time. A penguin can't also be a rooster. A pineapple is a fruit, but doesn't mean a pineapple can also not be a fruit.

So, one thing you said was, "You can call something a different name, but that doesn't change what it actually is."

Sure. And "A" and "B" can represent different names. So one thing we can be doing when we say that A is B is using the two different names. "Robert is Bob."

Another thing we can be doing--often in conjunction with different names--is focusing on a different set of facts about the thing in question.

For example, the morning star is the evening star. The different set of facts is that in the one case, we're talking about the "star" (it's not actually a star, though) we often see as the brightest star in the morning--it's often the last "star" we can see prior to sunrise, and in the other case, we're talking about the "star" we see in the evening--often the brightest/first star we can see at dusk. In both cases, we're actually referring to the planet Venus.

Another example there: Bruce Wayne is Batman. "Bruce Wayne" typically refers to the person in question in his everyday guise, as an uber-rich philanthropist businessman, etc. "Batman" typically refers to him in his crime-fighting superhero capacity. Each side, which is accompanied by different names, focuses on a different set of facts about the same person.

Those are examples where A is B. "The morning star is the evening star"--they both refer to the planet Venus. "Bruce Wayne is Batman"--they both refer to a particular person, as does "Robert is Bob."
