5 ideas

3. Truth / C. Correspondence Truth / 3. Correspondence Truth critique

2572	Logical truth seems much less likely to 'correspond to the facts' than factual truth does [Haack]
	Full Idea: It is surely less plausible to suppose that logical truth consists in correspondence to the facts than that 'factual' truth does.
	From: Susan Haack (Philosophy of Logics [1978], 7.6)

3. Truth / F. Semantic Truth / 1. Tarski's Truth / a. Tarski's truth definition

2570	The same sentence could be true in one language and meaningless in another, so truth is language-relative [Haack]
	Full Idea: The definition of truth will have to be, Tarski argues, relative to a language, for one and the same sentence may be true in one language, and false or meaningless in another.
	From: Susan Haack (Philosophy of Logics [1978], 7.5)

15. Nature of Minds / B. Features of Minds / 4. Intentionality / b. Intentionality theories

3158	Theories of intentionality presuppose rationality, so can't explain it [Dennett]
	Full Idea: Intentional theory is vacuous as psychology because it presupposes and does not explain rationality or intelligence.
	From: Daniel C. Dennett (Brainstorms:Essays on Mind and Psychology [1978], p.15?)
	A reaction: Virtually every philosophical theory seems to founder because it presupposes something like the thing it is meant to explain. I agree that 'intentionality' is a slightly airy concept that would probably reduce to something better.

17. Mind and Body / A. Mind-Body Dualism / 7. Zombies

12727	It's impossible, but imagine a body carrying on normally, but with no mind [Leibniz]
	Full Idea: If it could be supposed that a body exists without a mind, then a man would do everything in the same way as if he did not have a mind, and men would speak and write the same things, without knowing what they do. ...But this supposition is impossible.
	From: Gottfried Leibniz (Paper of December 1676 [1676], A6.3.400), quoted by Daniel Garber - Leibniz:Body,Substance,Monad 5
	A reaction: This is clearly the zombie dream, three centuries before Robert Kirk's modern invention of the idea. Leibniz's reason for denying the possibility of zombies won't be the modern physicalist reason.

17. Mind and Body / B. Behaviourism / 3. Intentional Stance

3159	Beliefs and desires aren't real; they are prediction techniques [Dennett]
	Full Idea: Intentional systems don't really have beliefs and desires, but one can explain and predict their behaviour by ascribing beliefs and desires to them. This strategy is pragmatic, not right or wrong.
	From: Daniel C. Dennett (Brainstorms:Essays on Mind and Psychology [1978], p.7?)
	A reaction: If the ascription of beliefs and desires explains behaviour, then that is good grounds for thinking they might be real features of the brain, and even if that is not so, they are real enough as abstractions from brain events, like the 'economic climate'.
