comment on my previous post by Allan Seltzer. As he says, "Mind cannot be reduced to brain". To be clear, mind is enabled but not reducible to brain. Psychiatry hasn't always been as clear about this as it should have been. In fact, it has always hankered after a simple reductionist solution to the issue of mental illness. It tends to think the problem must be a brain disorder, but this is an illusion. We're surprised when this is pointed out and it seems to leave us with too complex a clinical situation to manage. So we naturally shy away from it.
Is it realistic to think that psychiatry's future may be non-reductionistic? Probably not! Psychiatry hasn't changed much since its modern inception with the introduction of the successful anatomoclinical way of viewing disease. It's understandable that mental illness has been expected to follow the path of physical illness, which is seen as being caused by bodily pathology. The trouble is that it doesn't. I agree with Allan that psychiatry should become non-reductionistic. But there are too many entrenched interests to be overcome, not least that much of research is based on hoping for the physical clue to mental illness. People will continue to wish for a simple, quick, cheap, painless and complete cure for their mental health problems. It's easier if the solution's in the brain.
