Do you agree that at time t1, this particular farmer looked out into a particular field at a particular piece of cloth and mistook it for a cow?
— creativesoul
Yep. And?
Starting at "there is a cow in the field" does not consider the false belief, the case of mistaking cloth for cow, the belief that a particular piece of cloth in a particular field is a cow.
— creativesoul
So what? — neomac
Smith believed the disjunction was true because Jones owned a Ford (because P was true). The disjunction was not true because P was true. It was true because Q was true. Smith's belief was false.
— creativesoul
I agree with this. There's a question you don't include in your summary - whether Smith was justified in believing that Jones owned a Ford. Gettier's answer is that he was. That's the situation that generates the confusion that people feel about these cases. — Ludwig V
Belief that "'P or Q' is true because P" is not equivalent to belief that "P or Q" is true.
— creativesoul
But surely is one part of a disjunction is true, the whole disjunction is true. "Jones owned a Ford or Brown is in Barcelona" is true if Jones owned a Ford. Yes? Also "Jones owned a Ford or Brown is in Barcelona" is true if Brown is in Barcelona. Yes? That's all I'm saying. — Ludwig V
Seems to me that all Gettier cases show problems with the conventional accounting practices.
— creativesoul
I'm sorry, but I don't understand what you mean by conventional or unconventional accounting practices. Can you please explain? — Ludwig V
...the fact that available evidences fit enough into a cow-shape perceptual template — neomac
...plus the fact that no other justificatory practice more reliable than judging by habit... — neomac
I would claim "mistaking cloth for cow explains the belief that there is a cow in field" — neomac
Are we in agreement that the farmer sees a cloth and mistakes cloth for cow at time t1, but he does not know that?
— creativesoul
Yep. — neomac
I am using a variation of Kant’s definition of synthetic and analytic truths, one which is defined in terms of necessity and contingency and not containment and non-containment. — TheGreatArcanum
In short, it seems to me that Gettier case ought to be possible. Perhaps the real Gettier problem is why it is so hard to develop one that commands general agreement or to articulate a general solution. — Ludwig V
"Report" implies that we are talking to someone other than the farmer. So we report in the first way. If we were talking to the farmer, he would obviously not recognize what we would say. But to repeat to him the words he would use would suggest that we share his belief, so I can't use those. Before I can say anything to him, I have to ensure that we both understand the reference of the sentence. I must correct his mistake. “You know that cow in the field? Well actually it’s a piece of cloth.” or “I’m afraid that cow in the field is actually a piece of cloth” would do the trick. — Ludwig V
I'm afraid I'm one of those who people who see every sentence as a (potential) speech-act so the context, including the audience, always needs to be considered. — Ludwig V
I don't understand your diagnosis of Gettier's case 1. I think you've misremembered it. — Ludwig V
If I understand you rightly (and I'm not sure I have), your diagnosis of Case 2 is complicated by the fact that "P or Q" is true iff P is true or Q is true. So, according to Gettier and me, if Smith believes that P, they are justified in believing that P or Q. But, as you say P is false, yet, as Gettier tells us, Q is true. Smith's justification relies on P and the truth relies on Q. It's that mismatch that creates the problem. My solution to this example is to point out that Smith's justification fails and so he cannot know P or Q, which can be summarized as "no false lemmas".
the summary is altogether mistaken now
— creativesoul
@invizzy apparently he changed his views. — neomac
Are we in agreement that the farmer sees a cloth and mistakes cloth for cow at time t1, but he does not know that?
— creativesoul
Yep. — neomac
Here is a more straightforward answer: we all learnt to report S’belief at t1 based on what S says at t1. That’s the practice. — neomac
The expression "perceptual belief", as I use it, it's simply pointing to the genesis of that belief. If a belief is processed out of perceptual evidences, it's perceptual, if it's processed out of other propositions through reasoning it can be deductive or inductive belief, if it's processed out of a communicative channel it's a transmitted belief, etc.
This is at least part of my background assumptions while thinking about justification. — neomac
There certainly seems to be a problem about the farmer’s belief that a piece of cloth is a cow. You seem to be assuming that in reporting the farmer’s beliefs, you need to use words that he would have done, and he certainly wouldn’t have said that a piece of cloth was in the field. The tricky bit is that that is exactly how we would formulate his belief and we can’t say that there’s a cow in the field (unless we are referring to the cow that is in the field, which would be very misleading.)
First off, “see” is a factive verb. In reporting what people see, we need to report what they actually see, not what they think they see. When we report what they think they see, we have to make it clear, so we need to report, not that he sees a cow in the field, but that he believes he sees a cow in the field, or that he sees what he believes is a cow in the field.
We focus too much, in these discussions, on what people say in reporting their own beliefs. But that is only one way that people show what they believe. Their beliefs also show in what they do and in other things that they say. That’s how we know that he believes that a piece of cloth is a cow. But I would use that way of putting it only to other people, not to the farmer himself. Curiously, if I was telling the farmer about his mistake, I would say “you know that cow in the field? Well actually it’s a piece of cloth.” Or “I’m afraid that cow in the field is actually a piece of cloth”. — Ludwig V
Everything can be identified under many descriptions. We use the one that is most appropriate for the context, including the method of identification that works for our audience. When we come to reporting the belief (and knowledge) of other people, we do not stick to the reference that they are using or would use; we use the reference that works for the audience we are reporting to. After all, the point is to enable our audience to understand.
It is complicated, so I hope this is reasonably clear.
They concern particular perceptual beliefs. — neomac
The target proposition in the farmer example is "There is a cow in the field" and the story tells us that there is a cow in the field. How is that false? However, it is true that the farmer is not justified in believing it... — Ludwig V
...But Gettier has an argument that he is justified in believing it nonetheless, so you need to show that argument is invalid... — Ludwig V
...You are advocating a version of the "no False Lemmas" reply, which I agree with. I'm not clear whether you agree with my argument for that reply and it would be interesting to know whether you agree or have a different argument to refute Gettier's argument. — Ludwig V
It is tempting to think that when a flaw has been found in a bad argument, it is not necessary to pursue the matter further. But there is more than one problem with Gettier cases, and the expectation that they either meet the definition criteria or they do not is another one; the target proposition is always partly right and partly wrong. — Ludwig V
That particular farmer sees that particular piece of cloth in that particular field at that particular time, and mistakenly believes at that particular moment in time that that particular piece of cloth in that particular field is a cow or a sheep(which one does not matter).
Are you denying this?
— creativesoul
Read what has already been written and ye shall be enlightened:
He believed (erroneously) that he was looking at a cow, when he was actually looking at a piece of cloth.
— Janus — Janus
There is no puzzle there of the kind that you seem to be attempting to nurture by virtue (or vice) of ambiguous usage of language (that is by substituting what we might say about the farmer's belief for how he would put his belief into words, to arrive at an absurd paradox, "believing that a piece of cloth is a cow", that might engender the illusion that it is of some significance, when it really is not). — Janus
The farmer certainly did not believe that a piece of cloth was a cow; how could he, since he didn't know it was a piece of cloth, and if he had known it was a piece of cloth, then how could he believe it to be a cow? He believed (erroneously) that he was looking at a cow, when he was actually looking at a piece of cloth. — Janus
There certainly seems to be a problem about the farmer’s belief that a piece of cloth is a cow. You seem to be assuming that in reporting the farmer’s beliefs, you need to use words that he would have done, and he certainly wouldn’t have said that a piece of cloth was in the field. — Ludwig V
...psychiatry definitely does have an aura of evilness about it which is hard to define. — introbert
This is more or less a typical Gettier case because the conclusion is an existential claim that is true in virtue of the existence of some particular: it is true that there is a cow in the field because this particular cow, let's call her Alice, is in the field. — Srap Tasmaner
My way of putting this raises some issues though: in what sense is the farmer's belief about Alice? This doesn't look good at all. Since Alice played no role in the farmer's belief formation, it's pretty clear Alice is no part of the content of the farmer's belief. Alice does play a part in the existential claim; Alice is what makes that claim true. — Srap Tasmaner
...he might have seen Alice and mistaken Alice for a bit of cloth flapping in the breeze — so not seen that Alice is a cow — and formed the mistaken belief that there's a bit of cloth in the field, which might also be Gettierly true. — Srap Tasmaner
...I don't think there is a remaining problem with the existential generalization after all because we can just enumerate it: if Alice, Bobbie, Clarabelle, and Dixie are the cows in the field, then the truth of such an existential claim as we're concerned with is a truth about at least one of those: one of those four ought to play a causal role in the farmer's belief, expressed as an existential generality...
...Suppose the farmer thinks the cow he's seeing is Clarabelle, when it's Alice, even though Clarabelle is out there in the dark. — Srap Tasmaner
@creativesoul, I think some of your concerns are addressed above. — Srap Tasmaner
I agree that
It is humanly impossible to knowingly be mistaken(to knowingly hold false belief).
— creativesoul
But I don't quite understand why you say it is humanly impossible. — Ludwig V
It seems to me self-contradictory to assert "I believe that p and it is not the case that p". It is equivalent to "p is true and p is false." (Moore's paradox, of course.)
And I don't understand what you mean when you say
Beliefs are not equivalent to propositional attitudes.
I was under the impression that belief was one of the paradigmatic propositional attitudes.
Perhaps you are referring to your point that
Believing that a cloth is a cow is not equivalent to believing that "a cloth is a cow" is true.
— creativesoul
It is true that sometimes people explicitly verbalize a belief, whether to themselves or others and sometimes they don't - and of course, animals believe things, but clearly don't verbalize them. But I don't understand why that makes any difference here.
