Blushing and the philosophy of mind

The introduction, an imaginary dialogue between a philosopher and a scientist, is followed by a brief discussion of the interactions between science, philosophy, and religion. Next comes an analysis of the three most popular philosophies of mind: classical mind-body dualism, computerism, and psychoneural monism. It is argued that the latter, held by medical psychologists since Hippocrates, and formulated explicitly by Cajal and Hebb, is the philosophy of mind that underlies contemporary cognitive and affective neuroscience. The standard objections to psychoneural monism (or materialism) are examined. Evolutionary psychology, though promissory, is judged to be more fancy than fact at its present stage. The conclusion is that the philosophy of mind is still in a poor shape, but that it can advance if it learns more from the science of mind. It would also help if scientific psychologists were to replace such tacitly dualistic expressions as "organ N instantiates (or subserves) mental function M" with "organ N performs mental function M", just as we say "the legs walk" instead of "walking is subserved by legs," and "the lungs breathe" instead of "the lungs instantiate breathing."
