Abstract
THAT a human action is in some sense identical with its physiological basis is true. The sense in which that identity is properly to be understood is a very subtle one, and although I shall make some suggestions about it here, this paper is designed chiefly to make the negative point that the identity is, at any rate, not properly to be understood in the sense that a physicalist would maintain. The physicalist theory of the identity of A and PB is analogous to the theory of mind-body identity maintained by central state materialists, but I shall not deal directly with the latter theory, for reasons that will soon become clear. All the same, if the present refutation of a physicalist identity of A and PB is successful, it will be seen to be a fortiori effective against the analogous mind-body identity.
