Terry announced: “Book game (cause it isn’t really a meme): Nearest Book, Page 23, Fifth sentence, Posted, with explanation.” OK, here goes:
When we talk of a green sensation, this talk is not equivalent simply to talk of “a state that is caused by grass, trees, and so on”.
This is from the Chalmer’s Conscious Mind book that I’ve talked about before; he’s recapitulating the standard philosophical idea of the phenomenal (“Known or derived through the senses rather than through the mind”). The paragraph continues:
We are talking about the phenomenal quality that generally occurs when a state is caused by grass and trees. If there is a causal analysis in the vicinity, it is something like “the kind of phenomenal state that is caused by grass, trees, and so on”. The phenomenal element in the concept prevents an analysis in purely functional terms.
By the way, it looks as if the entire text of the book is online, although the diagrams are missing and (inevitably) the pagination doesn’t match the printed version.
(We played this game before – a few months back, IIRC – but unlike some of these blog games it’s pretty much guaranteed to be different each time around.)
