15. Nature of Minds / B. Features of Minds / 3. Privacy
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
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).
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.
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
Skill comes from a general assumption obtained from thinking about similar things [Aristotle]
     Full Idea: A skill arises when from the many cases of thinking in experience a single general assumption is formed in connection with similar things.
     From: Aristotle (Metaphysics [c.324 BCE], 0981a04)
     A reaction: [He gives the administration of appropriate medicine as the example of a 'skill'] Note that it is 'thinking in' experience, rather than just the raw having of experiences. This is the intellectualist version of empirical abstractionism. I like it.
Aristotle distinguishes two different sorts of generality - kinds, and properties [Aristotle, by Frede,M]
     Full Idea: Aristotle counts as general not only properties but also the kinds, into which objects fall, i.e. the genera, species, and differentiae of substances; and these are to be differentiated strictly from properties.
     From: report of Aristotle (Metaphysics [c.324 BCE], kind) by Michael Frede - Individuals in Aristotle Intro
     A reaction: I take properties to be prior, since the kind of a thing is presumably decided by its properties. I'm increasingly thinking that 'general', 'generality' and 'generalisation' are far more useful words in philosophy than other words in that area.
15. Nature of Minds / C. Capacities of Minds / 6. Idealisation
Science is more accurate when it is prior and simpler, especially without magnitude or movement [Aristotle]
     Full Idea: A scientific subject will possess more accuracy (i.e. simplicity) the more that it is about conceptually prior and simpler things, and so it will be more accurate without than with magnitude being involved, and above all being without movement.
     From: Aristotle (Metaphysics [c.324 BCE], 1078a10)
     A reaction: Aristotle is especially concerned to show how we can achieve accuracy, even while abstracting away from the details of the objects we are studying. Frege should have studied Aristotle more closely.
