Life Science Library now claims to examine ‘the most complex of all biological organs: the human mind’, and scientists quite commonly make no distinction between mind and brain — they delight in talking about the brain classifying, decoding, perceiving, deciding or giving orders. And while resisting the conceptual muddle involved in talking of the brain doing what persons do, the identity hypothesis tries to provide a philosophically respectable basis for the equation of mind and brain, maintaining that ‘mind’ is just (...) a term for a group of activities and dispositions, and that these in turn are in some sense to be identified with brain activities or traces. On the other hand, from the point of view of religion and traditional philosophy the suggestion is completely unplausible — creative or inventive thought, and aesthetic, moral or religious experiences seem so far removed from mechanical or physiological processes that a good deal of softening up is necessary if any kind of identity theory is to get a fair hearing. This softening up is best carried out by considering the difficulties in the main rival philosophical view, interactionism. (shrink)
