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. |
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. |
467 | A virtue is a combination of intelligence, strength and luck [Ion] |
Full Idea: The virtue of each thing is a Triad: intelligence, strength, luck. | |
From: Ion (fragments/reports [c.435 BCE], B1), quoted by (who?) - where? |
6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
