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. |
12608 | Concepts are distinguished by roles in judgement, and are thus tied to rationality [Peacocke] |
Full Idea: 'Concept' is a notion tied, in the classical Fregean manner, to cognitive significance. Concepts are distinct if we can judge rationally of one, without the other. Concepts are constitutively and definitionally tied to rationality in this way. | |
From: Christopher Peacocke (Truly Understood [2008], 2.2) | |
A reaction: It seems to a bit optimistic to say, more or less, that thinking is impossible if it isn't rational. Rational beings have been selected for. As Quine nicely observed, duffers at induction have all been weeded out - but they may have existed, briefly. |
12605 | A sense is individuated by the conditions for reference [Peacocke] |
Full Idea: My basic Fregean idea is that a sense is individuated by the fundamental condition for something to be its reference. | |
From: Christopher Peacocke (Truly Understood [2008], Intro) | |
A reaction: For something to actually be its reference (as opposed to imagined reference), truth must be involved. This needs the post-1891 Frege view of such things, and not just the view of concepts as functions which he started with. |
12607 | Fregean concepts have their essence fixed by reference-conditions [Peacocke] |
Full Idea: The Fregean view is that the essence of a concept is given by the fundamental condition for something to be its reference. | |
From: Christopher Peacocke (Truly Understood [2008], 2.1) | |
A reaction: Peacocke is a supporter of the Fregean view. How does this work for concepts of odd creatures in a fantasy novel? Or for mistaken or confused concepts? For Burge's 'arthritis in my thigh'? I don't reject the Fregean view. |
12609 | Concepts have distinctive reasons and norms [Peacocke] |
Full Idea: For each concept, there will be some reasons or norms distinctive of that concept. | |
From: Christopher Peacocke (Truly Understood [2008], 2.3) | |
A reaction: This is Peacocke's bold Fregean thesis (and it sounds rather Kantian to me). I dislike the word 'norms' (long story), but reasons are interesting. The trouble is the distinction between being a reason for something (its cause) and being a reason for me. |
12604 | Any explanation of a concept must involve reference and truth [Peacocke] |
Full Idea: For some particular concept, we can argue that some of its distinctive features are adequately explained only by a possession-condition that involves reference and truth essentially. | |
From: Christopher Peacocke (Truly Understood [2008], Intro) | |
A reaction: He reached this view via the earlier assertion that it is the role in judgement which key to understanding concepts. I like any view of such things which says that truth plays a role. |
12610 | Encountering novel sentences shows conclusively that meaning must be compositional [Peacocke] |
Full Idea: The phenomenon of understanding sentences one has never encountered before is decisive against theories of meaning which do not proceed compositionally. | |
From: Christopher Peacocke (Truly Understood [2008], 4.3) | |
A reaction: I agree entirely. It seems obvious, as soon as you begin to slowly construct a long and unusual sentence, and follow the mental processes of the listener. |
541 | Virtue comes more from habit than character [Critias] |
Full Idea: More men are good through habit than through character. | |
From: Critias (fragments/reports [c.440 BCE], B09), quoted by John Stobaeus - Anthology 3.29.41 |
542 | Fear of the gods was invented to discourage secret sin [Critias] |
Full Idea: When the laws forbade men to commit open crimes of violence, and they began to do them in secret, a wise and clever man invented fear of the gods for mortals, to frighten the wicked, even if they sin in secret. | |
From: Critias (fragments/reports [c.440 BCE], B25), quoted by Sextus Empiricus - Against the Professors (six books) 9.54 |
