Abstract

The Introduction discusses the purpose of the book, which is to attempt to rejuvenate the philosophy of concepts by steering it toward a new course. The book argues, the Introduction explains, that progress in the psychology of concepts and in the budding neuropsychology of concepts is conditional on psychologists and neuropsychologists eliminating the notion of concept from their theoretical vocabulary. This eliminativist proposal is the last tenet of the hypothesis that is developed at length in this book — the Heterogeneity Hypothesis. The Introduction then outlines to contents of the chapters that follow.
