This book, which is historical, dialectical and opinionated, presents the mind-body problem as a debate between materialists about the mind and their opponents. It argues for a certain point of view, in particular for a Materialist solution to the problem.

D. M. Armstrong is emeritus professor in the School of Philosophy at the University of Sydney.
