"The concept of the individual is central to the understanding of behavior in economics. Different approaches in economics implicitly rely on different theories of the individual. Yet economics is guilty of using this very important concept without questioning how it is theorized. This book remedies this oversight." "The new approach put forward by John B. Davis employs identity analysis to understand theories of the individual in economics. It combines philosophy and economics to determine when theories of the individual are successful. With both heterodox and orthodox economics receiving a thorough analysis, this book is at once inclusive and systematic." "Davis has produced an original book that should become essential reading for all those interested in the study of economic philosophy and methodology, but will also be of great interest to philosophers and social scientists outside economics."--BOOK JACKET.
