The distinction between mental illness and bodily illness would seem to presuppose some sort of distinction between mind and body. But dualist theories that the mind is a substance separable from the body, or that mental events could occur without any bodily events, raise ancient conceptual problems, which I do not propose to review here. What I want to do is to examine the psychiatric implications of materialist theories, which hold that the mind is the brain, or a function of the brain. If all character has a basis in chemistry, can we still attribute some mental distress to character and some to chemistry, as if the two categories were different?
