This chapter will argue that the hypothesis that minds are brains has far more explanatory power
than does its main competing hypothesis that minds are souls. Later I will also consider two
prominent materialist views that resist identifying minds with brains: the functionalist view that minds
can be processes in many different physical systems, and the embodiment view that minds are states
of the whole body. I think that neither of these views contradicts my main claim that human minds are
brains, which is, however, radically incompatible with the commonsense view that minds are not
physical objects.
