In my comment, I contrasted P’s belief prospective at t1 with both Q’s belief prospective at t1 and P’s belief prospective at t2 (when she understood her belief at t1 to be wrong). And I said our report is accurate when it matches P’s belief prospective at time t1. — neomac
Indeed I reported that premise (there was a typo: I wrote “intenTional” instead of “intenSional”), b/c if you want to make a philosophical proposal that is appealing to me, or those holding the conventional view of belief ascription, you should feel intellectually compelled to show understanding toward what we are concerned about (de dicto report are necessary for rendering believers' p.o.v.), and prove by that that we are not talking past each other. The burden is on you, b/c it’s you who wants to challenge the conventional view, not the other way around.
Otherwise our exchange will just end up in butting heads against the wall of our diverging intuition pumps. It’s pointless. So we can work out our different views better if we start from common grounds or at least reciprocal concessions. — neomac
Yet one can wonder if all intensional belief ascriptions can be in principle replaced by extensional belief ascriptions without omitting the believer’s perspective. How? By rendering the believer’s perspective in terms of metalinguistic belief ascriptions (belief about the truth-value of some propositions).
This is why one can claim as valid both <Jack believes a broken clock is working> (extensional belief ascription) and <Jack believes the proposition “a broken clock is working” false> (extensional belief ascription rendering the believer’s perspective in metalinguistic terms).
Where is the benefit? At least, in preserving truth-value through substitution of co-referent terms, even for belief ascriptions, and without giving up on the believer’s perspective. — neomac
We commonly take a believer’s perspective on a given situation as a fundamental accuracy condition for belief ascriptions about him, and intensional belief ascriptions are designed for expressing this understanding — neomac
All I can say is that the most accurate report of someone’s belief at time t1 is the one that best matches the point of view of the believer at time t1. Why would I pick the point of view of some person P at time t2 (or some other person Q at time t1) as a criterium of accuracy for reporting P's belief at time t1? — neomac
SO now I am wondering if you have a clear grasp of what a proposition is. — Banno
I understand what you are arguing. You're just wrong. — frank
I just don't see anything here that supports your contention. — Banno
You're moving goal posts. — Harry Hindu
He never held an attitude towards the proposition (that broken clock is working) such that he believed it true. — creativesoul
Seems to me that this is clearly a belief that does not allow itself to be rendered in propositional form such that the believer would hold it to be true, or as true. — creativesoul
It's that "broken clock" is an extensional definition, while believes is an intensional operator.
The typical example of intension is
Jack believes Stephen King's first novel is The Shining.
If we stuck an extensional definition in there it would read
Jack believes that Carrie is The Shining.
Same thing. — frank
SO you do not understand that...
"the broken clock" is not a description Jack could correctly make?... — Banno
SO you do not understand that...
"The broken clock" could not be within the scope of Jack's belief? — Banno
The move to set it outside the scope of Jack's belief is due to the fact that it would be impossible for Jack to make such a statement based on his belief. — Harry Hindu
The belief under our consideration is problematic for the conventional rendering of belief as a propositional attitude. It is not problematic for rendering it in propositional form — creativesoul
As I said, this is the kind of de re belief ascription that we can use when we are not sure about a de dicto belief ascription (i.e. we don’t know what someone else’s beliefs are really about, see the case of the kid in the park). In the case of Jack, I would prefer that form of rendering, if e.g. I’m not sure whether Jack is holding contradictory beliefs or he simply ignores that that clock is not working. Certainly, if I knew that Jack ignores that clock is not working, I would prefer to say “Jack believes that clock is working” or “Jack mistakenly believes that clock is working” instead of “Jack believes of that broken clock that is working”, or worse, “Jack believes that broken clock is working”. — neomac
Mary's room is based upon the dubious presupposition that we can learn anything about seeing red without seeing red.
— creativesoul
In other words, qualia is ineffable. Why else can't Mary learn everything about red without seeing red? — Agent Smith
...the problem I have is with "Jack believed that a broken clock was working" since your are insisting on it. — neomac
You came up with this rendering based on the propositional calculus suggested here: “Can Jack look at a broken clock? Surely. Can Jack believe what the clock says? Surely. Why then, can he not believe that a broken clock is working?”.
So I proposed you the following propositional calculus: if one can render “I did/did not believed that p” as “p and I did/did not believe it” and vice versa. And asked you: why can’t we do the same with p="Jack believed that a broken clock was working"?
So I'm challenging you to explain why your propositional calculus is correct, and mine is wrong based on your own assumptions. This is the problem you should address, hopefully in a non ad-hoc way.
From Jack's point of view he doesn't believe anything about a broken clock, obviously, since he thinks the clock is not broken. Of course we can say that he believes of a broken clock that it is working. But so what; people entertain mistaken beliefs all the time? — Janus
What's your view regarding Russell's clock, Gettier's cases, and Moore's paradox?
— creativesoul
Not sure about it, also because knowledge is a wider issue. — neomac
Get it now? — neomac
I haven't thought about those specifics. Off the top of my head I'd say that Jack's belief is about a clock and it's condition of working, which begs the question as to whether the clock and its condition of working together form the content of the belief. What else could Jack's belief be about? — Janus
