Davidson's principle of Charity

In which I continue the wrestling with the asshole god of skepticism series. I try to refute global skepticism in 10 minutes :-) I do this by explaining the Quine-Davidson "principle of charity" which is a transcendental argument which shows that in order to have a conversation with somebody at all--in order to know that you are interpreting them correctly--you have invoke the "Principle of Charity" towards them. You have to attribute to them as much truth as possible. The remarkable conclusion is that anybody we can talk with at all we (A) know that we share most of our beliefs in common, and (B) we know that both of use are mostly correct.

Thank you for posting this! This is one of my favorite arguments. "Irrationality is not mere lack of reason, but a disease or perturbation of reason" (in "Rational Animals"). But Davidson said that we could still be brains in vats with true beliefs that are actually about our vat world. That isn't very comforting for the anti-skeptical realist.

But for example this means that the beliefs that you and I share (even if I were a demon) are true. most all of the beliefs you have are absolutly correct. What more cold you want from a solution to skepticism? omniscience? Even if this isn't an illusion there are always going to be places I can't go to--I can't check and see what's under the rocks on mars. But I do know that I am largely correct about the world as presented to my senses. What more do you want?

randy, nobody is denying that one can 'learn about illusions without knowing they are illusions'. This is satisfied by any belief you can imagine. if i think god exists, well then i have a true belief about an illusion. the point of the skepticism is that, as you have described it, we cant know whether we are being deluded in most things.

(cont, to Everett) if the demon puts you in an illusion (stuffs you in the matrix, say) it doesn't change anything--if you can talk with the demon about the world created by the matrix, you are still mostly correct about the world created by the matrix. Recall, its the SHARED world for which this works.

Hi Everett, if the demon is interception the communication, then you are triangulating with the demon, not the other person. If you can learn a language which the demon is presenting you with, its not essentially different talking with a demon, you're still going to share a lot of true beliefs about the world with the demon. If the demon is presenting you with an illusion, you are going to share a lot of true beliefs about the illusion. (cont)

[EverettsVLOG]

i agree with what you are saying - assuming that you share beliefs with someone is necessary in order to understand them IF they are thinking they same thing you are. But you DONT know if they are thinking anythign like what you are thinking, and you CANT know, epistemically. Even if the conversation runs smoothly, that could jsut be due to demons fucking with your interpretations of each other, in fact you might not even be talking to someone at all

[randyhelzerman]

I'd love to hear your latest thoughts about this.

[randyhelzerman]

(cont, to Everett) that way. It is a necessary precondition of learning somebody's language that they are mostly correct about the world you share. The kicker is that this also applies to your first language. If you can speak and have a conversation with anybody at all, you know that you both are mostly correct about the world you share, otherwise you wouldn't be able to make sense out of each other at all.

yea its pretty fun actually, im thinkin about going back to philosophy with my channel... was thinkin about recording a vid on my best solution to my skeptical arguments... it still doesnt get anyone any important epistemic access although thats not suprising. it is difficult to even set up any kind of philosophy because im convinced that in principle the manipulation of my consciousness by external entities does not have any logical bounds.

[randyhelzerman]

Think about language learning---a process which is explicitly epistemological. :-) If you are going to learn somebody's language from scratch, you have to assume that they are mostly correct about the world. If you don't make that assumption, you'll never be able to interpret them. For example, they tell you the word for "rabbit" is "gavagai"---but you interpret them as being mostly wrong, so you think that their word for rabbit isn't "gavagai". You'll never learn their language (cont)
