4 ideas

9. Objects / B. Unity of Objects / 2. Substance / b. Need for substance

16629	By comparing qualities and features, reason can gradually infer the nature of substance [Grosseteste]
	Full Idea: Awakened reason distinguishes color from size and shape from body and then shape and size from the substance of body, and so by drawing distinctions and abstracting, it arrives at a grasp of the substance of body, which supports size, shape and color.
	From: Robert Grosseteste (Commentary on 'Posterior Analytics' [1226], I.14), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 07.4
	A reaction: This optimistic view influenced Aquinas, and is called 'incrementalism' by Pasnau. It is the spirit of scientific essentialism, and a nice instance of inference to the best explanation (though 'substance' in itself explains virtually nothing).

15. Nature of Minds / B. Features of Minds / 1. Consciousness / a. Consciousness

6668	If the present does not exist, then consciousness must be memory of the immediate past [Marshall]
	Full Idea: Given the paradoxical nature of the 'present' moment, maybe we should understand ALL consciousness as memory, with the split second of the 'specious present' being very vivid and very brief memory, with the rest of the mind remembering in lower degrees.
	From: David Marshall (talk [2004]), quoted by PG - Db (ideas)
	A reaction: This strikes me as a highly plausible, and very illuminating remark. For the time paradox, see Ideas 1904 and 5102. Anyone researching consciousness in the brain should think about this, because it will just be a special sort of memory neurons.

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'.
