if there is no access to "reality," then presumably there is no reason to set up a knowledge/belief, reality/appearance distinction in the first place. But claims that beliefs are "merely appearance," presuppose such a distinction. — Count Timothy von Icarus
Yes, I understand that. But I am talking about our in situ situation. Perhaps what we consider we know now may turn out not to be the case.Wl, yes. Sometimes folk get things wrong. They think they know stuff when they don't. And the only way this can happen is if they believe something that is not true.
So there is a difference between believing and knowing: If something is known, it is true. — Banno
Was this directed at me? Is that what you think I am saying and also are you saying I think I am clever?Folk think it cleaver to say that we don't know anything. The implication is that there are no facts. That leads to all sorts of inconsistencies. — Banno
Right, but I am looking at the now situation. The now situation means that where there does not seem to be an error, there may be an error. We don't know, if we are adding true to the criteria, if it will remain true. Now. Saying something is well justified and not falsified I get. And I think calling those things knowledge is useful. But then to add that it is also true I think is hubris. I treat those things as true. I work with them as true or working, but I have no extra step where I justify X according to a rigorous methodolgy and/or note that others have, check to see if somewhere it has been falsified, and then I make the check to see it is true step. So far it is not false. So far it is working better than anything else.You can't "realise your error" unless there is error. Error occurs when you believe something that is not true. For you to occasionally be wrong, you must also sometimes be right. — Banno
Sure.For you to occasionally be wrong, you must also sometimes be right. — Banno
But problem is that you do not KNOW that thus your belief is unjustified — SpaceDweller
The creation of this thread is motivated by a claim made by Chet Hawkins:
Knowledge is only belief.
— Chet Hawkins
Chet elaborates:
So I could/should rest on that statement alone as it is incontrovertible.
But the quislings out there will want to retreat behind 'facts' and 'knowledge' delusions. So, it's best I turn my hat around and address the concepts more thoroughly.
But let's take this outside.
— Chet Hawkins
I think there is a valid distinction between knowledge and belief, although I also think that much of what is generally considered to be knowledge might be more accurately classed as belief. It may well turn out that I am sympathetic to Chet's belief. Let's see...
Chet says that statement is incontrovertible. I would like to see an argument to support that contention. — Janus
Knowledge is an assertation of identity backed by deductive reasoning. — Philosophim
Is there some reason I should accept your definition? — wonderer1
A belief is a propositional attitude.That is, it can be placed in a general form as a relation between someone and a proposition. So "John believes that the sky is blue" can be rendered as
Believes (John, "The sky is blue")
B(a,p)
There's ill will in some circles towards this sort of analysis. Think of this as setting up a basic structure or grammar for belief. A belief is a relation between an individual and a proposition. That there is much more to be said about belief is not in contention; this is just a place to start. This is set as a falsifiable proposition. If there are any examples of beliefs that cannot be stated as relations between individuals and propositions, this proposal would have to be revisited.
It has been suggested that animal and other non-linguistic beliefs are a falsification of this suggestion. The argument is that non-linguistic creatures can have beliefs and yet cannot express these beliefs as propositions, and that hence beliefs cannot be propositional attitudes. But that is a misreading of what is going on here. Any belief, including that of creatures that cannot speak, can be placed in the form of a propositional attitude by those who can speak. A cat, for example, can believe that its bowl is empty, but cannot put that belief in the form B(a,p).
Belief does not imply truth
One obvious consequence of a belief being a relation between an individual and a proposition is that the truth of the proposition is unrelated to the truth of the belief.
That is, folk can believe things that are untrue. Or not believe things that are true.
A corollary of this is that belief does not stand in opposition to falsehood, but to doubt. Truth goes with falsehood, belief with doubt. And at the extreme end of belief we find certainty. In certainty, doubt is inadmissible.
If belief does not imply truth, and if one holds to the Justified True Belief definition of knowledge, it follows that belief does not imply knowledge.
The individual who has the belief holds that the proposition is true.
This is, if you like, the significance of a belief statement. It follows from Moore's paradox, in which someone is assume to believe something that they hold not to be true. For example:
"I believe the world is flat, but the world is not flat".
While this is difficult to set out as a clear contradiction, there is something deeply unhappy about it. The conclusion is that one thinks that what one believes is indeed true.
Note that Moore's paradox is in the first person. "John believes the world is flat, but the world is not flat" is not paradoxical - John is just wrong. "John believes that the world is flat and John believes the world is not flat" - John is inconsistent.
This perforative paradox comes about only when expressed in the first person.
One might think it so trivial that it is not worth saying: to believe some proposition is to believe that proposition to be true.
That is, talk of belief requires talk of truth.
One might be tempted, perhaps by pragmatism or by Bayesian thoughts, to replace that with measures of probability. You might think yourself only 99.99% certain that the cat is on the mat, and suppose thereby that you have banished truth. But of course, one is also thereby 99.99% certain that "the cat is on the mat" is true.
Belief makes sense of error
Austin talked of words that gain their meaning - use - mostly by being contrasted with their opposite. His example was real.
"it's not a fake; it's real"
"it's not a mirage, it's real!"
It's not a mistake - it's real"
and so on.
Belief can be understood in a similar fashion, as gaining it's usefulness from the contrast between a true belief and a false belief. That is, an important aspect of belief is that sometimes we think that something is the case, and yet it is not.
We bring belief into the discourse in order to make sense of such errors.
Belief is dynamic
Beliefs change over time. It follows that a decent account of belief must be able to account for this dynamism.
Beliefs explain but do not determine actions
Beliefs are used to explain actions. Further, such explanations are causal and sufficient. So if we have appropriate desires and a beliefs we can explain an action.
So, given that John is hungry, and that John believes eating a sandwich will remove his hunger, we have a sufficient causal explanation for why John ate the sandwich.
One may act in ways that are contrary to one's beliefs. A dissident may comply in order to protect herself and her family.
So given that John is hungry, and has a sandwich at hand, it does not follow that John will eat the sandwich.
An individual's belief is inscrutable
One can act in ways contrary to one's beliefs. It's a result of the lack of symmetry between beliefs and actions mentioned above - Beliefs explain but do not determine actions. Thanks due to Hanover and @Cabbage Farmer.
Any belief can be made to account for any action, by adding suitable auxiliary beliefs. — Banno
Falsification was first developed by Karl Popper in the 1930s. Popper noticed that two types of statements are of particular value to scientists. The first are statements of observations, such as 'this is a white swan'. Logicians call these statements singular existential statements, since they assert the existence of some particular thing. They can be parsed in the form: there is an x which is a swan and is white.
The second type of statement of interest to scientists categorizes all instances of something, for example 'all swans are white'. Logicians call these statements universal. They are usually parsed in the form for all x, if x is a swan then x is white.
Scientific laws are commonly supposed to be of this form. Perhaps the most difficult question in the methodology of science is: how does one move from observations to laws? How can one validly infer a universal statement from any number of existential statements?
Inductivist methodology supposed that one can somehow move from a series of singular existential statements to a universal statement. That is, that one can move from ‘this is a white swan', “that is a white swan”, and so on, to a universal statement such as 'all swans are white'. This method is clearly logically invalid, since it is always possible that there may be a non-white swan that has somehow avoided observation. Yet some philosophers of science claim that science is based on such an inductive method.
Popper held that science could not be grounded on such an invalid inference. He proposed falsification as a solution to the problem of induction. Popper noticed that although a singular existential statement such as 'there is a white swan' cannot be used to affirm a universal statement, it can be used to show that one is false: the singular existential statement 'there is a black swan' serves to show that the universal statement 'all swans are white' is false, by modus tollens. 'There is a black swan' implies 'there is a non-white swan' which in turn implies 'there is something which is a swan and which is not white'.
Although the logic of naïve falsification is valid, it is rather limited. Popper drew attention to these limitations in The Logic of Scientific Discovery, in response to anticipated criticism from Duhem and Carnap. W. V. Quine is also well-known for his observation in his influential essay, "Two Dogmas of Empiricism" (which is reprinted in From a Logical Point of View), that nearly any statement can be made to fit with the data, so long as one makes the requisite "compensatory adjustments." In order to falsify a universal, one must find a true falsifying singular statement. But Popper pointed out that it is always possible to change the universal statement or the existential statement so that falsification does not occur. On hearing that a black swan has been observed in Australia, one might introduce ad hoc hypothesis, 'all swans are white except those found in Australia'; or one might adopt a skeptical attitude towards the observer, 'Australian ornithologists are incompetent'. As Popper put it, a decision is required on the part of the scientist to accept or reject the statements that go to make up a theory or that might falsify it. At some point, the weight of the ad hoc hypotheses and disregarded falsifying observations will become so great that it becomes unreasonable to support the theory any longer, and a decision will be made to reject it.
In place of naïve falsification, Popper envisioned science as evolving by the successive rejection of falsified theories,rather than falsified statements. Falsified theories are replaced by theories of greater explanatory power. Aristotelian mechanics explained observations of objects in everyday situations, but was falsified by Galileo’s experiments, and replaced by Newtonian mechanics. Newtonian mechanics extended the reach of the theory to the movement of the planets and the mechanics of gasses, but in its turn was falsified by the Michelson-Morley experiment and replaced by special relativity. At each stage, a new theory was accepted that had greater explanatory power, and as a result provided greater opportunity for its own falsification.
Naïve falsificationism is an unsuccessful attempt to proscribe a rationally unavoidable method for science. Falsificationism proper on the other hand is a prescription of a way in which scientists ought to behave as a matter of choice. Both can be seen as attempts to show that science has a special status because of the method that it employs. — Banno
Sorry, I know you are paraphrasing another postbeliefs are justified if they're true and unjustified if they're false. — flannel jesus
My suggestion is not that we can't know anything, but rather that adding that it is true, creates a problem. We work with it as if it is true. We have rigor in what we decide to consider knowledge. We don't add on to it being well justified and not (yet) falsified that it is also true. — Bylaw
This works only in limited cases. Some counterexamples have already been given. Here's another: Supose you are playing Checkers and your opponent reaches over and moves one of your pieces - yo say "You can't move my pieces!" Would you accept their reply if it were "HA, but there you have it - I have falsified that rule: I can move your pieces!"I work with them as true or working, but I have no extra step where I justify X according to a rigorous methodolgy and/or note that others have, check to see if somewhere it has been falsified, and then I make the check to see it is true step. So far it is not false. So far it is working better than anything else. — Bylaw
Well, you kind of backed off on your position I think.
When you dither, I cannot tell what you mean to say or write or believe. — Chet Hawkins
All facts are a subset of all beliefs.
Knowledge is not knowing and the word 'to know' is stupid therefore. It implies a failure in understanding. — Chet Hawkins
"Doubt may be an unpleasant condition, but certainty is absurd" - Voltaire was right. — Chet Hawkins
We all operate in life only from a well of beliefs. — Chet Hawkins
The fact that many people share the same facts has not so much bearing on the factuality of any fact. As a matter of fact, 'facts' are always wrong in some way. That is TRUE and more factual than most facts, because as a part of that fact we ALREADY INCLUDE the flexibility that fact is only belief. — Chet Hawkins
↪Chet Hawkins - So are you saying that a fact which claims to be nothing more than a belief is better than a fact which claims to be something more than a belief? — Leontiskos
I think it is good to realize that knowledge is form of belief. I think that adds a note of humility. What we are sure is true today may be overturned. — Bylaw
If you take JTB (above) into the picture then that's an argument against it because belief only is insufficient. — SpaceDweller
Belief is assent (true if warranted, opinion if unwarranted, delusion if its negation is warranted).
Knowledge consists of truths or not-yet-falsified claims the statuses of which are independent of dis/belief. — 180 Proof
I think there is a valid distinction between knowledge and belief,
— Janus
The former is a subset of the latter. Different people/groups have different reasons for saying this batch of beliefs over here, they've got promise or they sure seem to be working so far or they fit X and Y really well and those over there don't fit it so well and those over there we can't make sense of to even tell. — Bylaw
Twaddle.What distinguishes a 'fact' from a belief is that THAT PERSON ONLY (<--- yup) has decided that enough evidence exists to make that fact iota something that is fairly far along the match curve towards infinity, e.g. perfection. For them its a fact. — Chet Hawkins
I think there is a valid distinction between knowledge and belief, although I also think that much of what is generally considered to be knowledge might be more accurately classed as belief.
— Janus
As do I, but if there is a distinction, putting belief and knowledge in the same class kinda invalidates it. — Mww
Still, regarding the question in general, this….
What distinguishes a 'fact' from a belief is that THAT PERSON ONLY (…) has decided….
— Chet Hawkins
….would be the focal point of the issue, insofar as whether opinion, belief or knowledge, any relative judgement of truth is a purely subjective effort. And even if that is the case, brain states aside, still leaves the method by which it happens. — Mww
If he'd said knowledge was a subset of belief, that what we know is a subset of what we believe, that might have made sense.So, here you assert that all facts are a subset of beliefs. This does not accord with the common concepts of 'fact' and 'belief'. 'Fact' signifies what is the case regardless of what anyone believes. — Janus
Clearly not.Say we have accepted some not-yet-falsified claim and count it as knowledge, and then it becomes falsified. Was it ever knowledge in that case? — Janus
All knowledge requires belief. — ENOAH
Paraphrased to illustrate:
Jesus: nothing beats belief. Belief will move mountains. If you have belief the size of a mustard seed you will say to that mountain move, and it will move.
Hui neng: came across two of his disciples debating over whether the wind was moving the flag or the flag was moving. "It is neither wind nor flag," said the 6th patriarch of Cha'an. "It is your mind moving."

I've read it. I guess I was wondering if you were interested in considering a different perspective. — wonderer1
It's not rare for me to accept that I know things, based on my intuition having been highly trained and tested in some fairly specific areas. Is there some reason I should accept your definition? — wonderer1
If we trace your logic back to its roots, we are going to find intuitions anyway, don't you think? — wonderer1
And ↪fdrake laid out an excellent argument against the statement "Knowledge is merely belief" -- sometimes, to expand on fdrake, knowledge is action, and has nothing to do with what people say! A totally orthogonal category to yourthe notion that knowledge is merely belief. — Moliere

I'll argue that knowing-that reduces to knowing-how; so by way of an example knowing that water boils at 100℃ is knowing how to boil the kettle and how to use a thermometre and how to answer basic physics questions and so on. I take this as a corollary of meanign as use. The meaning of "water boils at 100℃" is what we are able to do with it.There is 'knowing how', there is the knowing of familiarity and there is 'knowing that'. I think the salient question in this thread concerns only 'knowing that' or propositional knowing, because the other two categories do not necessarily involve belief. — Janus
No, but actual knowledge is fallibilistic.Say we have accepted some not-yet-falsified claim and count it as knowledge, and then it becomes falsified. Was it ever knowledge in that case? — Janus

Notice also that this approach makes knowedge more social or communal. It is part of our langauge use. — Banno
