4 ideas

1. Philosophy / H. Continental Philosophy / 4. Linguistic Structuralism

23123	Basic to human culture are binary oppositions, such as eating raw or cooked [Levi-Strauss, by Green,TH]
	Full Idea: Lévi-Strauss made canonic to French structuralism the idea that human culture could be understood through a series of binary oppositionsn - the difference between what could be eaten raw and what cooked being one of the most fundamental.
	From: report of Claude Lévi-Strauss (works [1950]) by T.H. Green - Prolegomena to Ethics 1
	A reaction: My guess is that such oppositions can often be illuminating, but will always be eventually judged as too simplistic.

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.

20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act

7861	Libet says the processes initiated in the cortex can still be consciously changed [Libet, by Papineau]
	Full Idea: Libet himself points out that the conscious decisions still have the power to 'endorse' or 'cancel', so to speak, the processes initiated by the earlier cortical activity: no action will result if the action's execution is consciously countermanded.
	From: report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by David Papineau - Thinking about Consciousness 1.4
	A reaction: This is why Libet's findings do not imply 'epiphenomenalism'. It seems that part of a decisive action is non-conscious, undermining the all-or-nothing view of consciousness. Searle tries to smuggle in free will at this point (Idea 3817).

6660	Libet found conscious choice 0.2 secs before movement, well after unconscious 'readiness potential' [Libet, by Lowe]
	Full Idea: Libet found that a subject's conscious choice to move was about a fifth of a second before movement, and thus later than the onset of the brain's so-called 'readiness potential', which seems to imply that unconscious processes initiates action.
	From: report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.9
	A reaction: Of great interest to philosophers! It seems to make conscious choices epiphenomenal. The key move, I think, is to give up the idea of consciousness as being all-or-nothing. My actions are still initiated by 'me', but 'me' shades off into unconsciousness.
