7 ideas

6. Mathematics / C. Sources of Mathematics / 6. Logicism / b. Type theory

6409	The 'simple theory of types' distinguishes levels among properties [Ramsey, by Grayling]
	Full Idea: The idea that there should be something like a distinction of levels among properties is captured in Ramsey's 'simple theory of types'.
	From: report of Frank P. Ramsey (works [1928]) by A.C. Grayling - Russell
	A reaction: I merely report this, though it is not immediately obvious how anyone would decide which 'level' a type belonged on.

9. Objects / D. Essence of Objects / 3. Individual Essences

15990	Every individual thing which exists has an essence, which is its internal constitution [Locke]
	Full Idea: I take essences to be in everything that internal constitution or frame for the modification of substance, which God in his wisdom gives to every particular creature, when he gives it a being; and such essences I grant there are in all things that exist.
	From: John Locke (Letters to Edward Stillingfleet [1695], Letter 1), quoted by Simon Blackburn - Quasi-Realism no Fictionalism
	A reaction: This is the clearest statement I have found of Locke's commitment to essences, for all his doubts about whether we can know such things. Alexander says (ch.13) Locke was reacting against scholastic essence, as pertaining to species.

11. Knowledge Aims / A. Knowledge / 4. Belief / c. Aim of beliefs

3212	Beliefs are maps by which we steer [Ramsey]
	Full Idea: Beliefs are maps by which we steer.
	From: Frank P. Ramsey (works [1928]), quoted by Georges Rey - Contemporary Philosophy of Mind p.259 n5

11. Knowledge Aims / B. Certain Knowledge / 1. Certainty

15994	If it is knowledge, it is certain; if it isn't certain, it isn't knowledge [Locke]
	Full Idea: What reaches to knowledge, I think may be called certainty; and what comes short of certainty, I think cannot be knowledge.
	From: John Locke (Letters to Edward Stillingfleet [1695], Letter 2), quoted by Simon Blackburn - Quasi-Realism no Fictionalism
	A reaction: I much prefer that fallibilist approach offered by the pragmatists. Knowledge is well-supported belief which seems (and is agreed) to be true, but there is a small shadow of doubt hanging over all of it.

15. Nature of Minds / B. Features of Minds / 3. Privacy

7522	A full neural account of qualia will give new epistemic access to them, beyond private experience [Churchlands]
	Full Idea: When the hidden neurophysiological structure of qualia (if there is any) gets revealed by unfolding research, then we will automatically gain a new epistemic access to qualia, beyond each person's native and exclusive capacity for internal discrimination.
	From: Churchland / Churchland (Recent Work on Consciousness [1997])
	A reaction: Carefully phrased and hard to deny, but something is impenetrable. What experience does an insect have when it encounters ultra-violet light? Nothing remotely interesting about their qualia is likely to emerge from the study of insect brains.

15. Nature of Minds / B. Features of Minds / 5. Qualia / c. Explaining qualia

7521	It is question-begging to assume that qualia are totally simple, hence irreducible [Churchlands]
	Full Idea: One of the crucial premises of the antireductionists - concerning the intrinsic, nonrelational, metaphysical simplicity of our sensory qualia - is a question-begging and unsupported assumption.
	From: Churchland / Churchland (Recent Work on Consciousness [1997])
	A reaction: This is a key point for reductionists, with emphasis on the sheer numbers of connections involved in a simple quale (I estimate a billion involved in one small patch of red).

7523	The qualia Hard Problem is easy, in comparison with the co-ordination of mental states [Churchlands]
	Full Idea: The so-called Hard Problem (of qualia) appears to be one of the easiest, in comparison with the problems of short-term memory, fluid and directable attention, the awake state vs sleep, and the unity of consciousness.
	From: Churchland / Churchland (Recent Work on Consciousness [1997])
	A reaction: Most of their version of the Hard Problems centre on personal identity, and the centralised co-ordination of mental events. I am inclined to agree with them. Worriers about qualia should think more about the complexity of systems of neurons.
