The brain/body problem

Abstract

It is a commonplace of contemporary thought that the mind is located in the brain. Although there have been some challenges to this view, it has remained mainstream outside of a few specialized discussions, and plays a prominent role in a wide variety of philosophical arguments. It is further assumed that the source of this view is empirical. I argue it is not. Empirical discoveries show conclusively that the brain is the central organ of mental life, but do not show that it is the mind's location. The data are just as compatible with a view where mentality is a human capacity on the model of circulation or respiration, with the brain playing the same kind of role as the heart or lungs. The standard conception of the brain as the locus of mind stems, I claim, from the imposition of a Cartesian conception of the self on a materialist ontology. Recognizing that the empirical data do not justify such a move casts doubt on the foundations of a number of philosophical discussions and raises new questions about the nature of the psychological subject.
