4 ideas

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 / 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'.

27. Natural Reality / C. Space / 6. Space-Time

14014	Space alone, and time alone, will fade away, and only their union has an independent reality [Minkowski]
	Full Idea: Henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.
	From: Hermann Minkowski (Space and Time [1908], Intro)
	A reaction: Notice the qualification that it is a 'kind of' union. Deep confusion arises from exaggerating the analogy between space and time. Craig Bourne remarks (2006:157) that this shows independence of measurement, not of reality

27. Natural Reality / G. Biology / 3. Evolution

3804	Darwin's idea was the best idea ever [Dennett]
	Full Idea: If I were to give an award for the single best idea anyone has ever had, I'd give it to Darwin.
	From: Daniel C. Dennett (Darwin's Dangerous Idea [1995], §1.1)
