David Charles has been a Fellow in Philosophy at Oriel College, University of Oxford, from 1978 and a Research Professor since 2006. He has held Visiting Professorships at Rutgers, U.C.L.A., Tokyo Metropolitan, and Venice Universities and has written on various aspects of Aristotle's philosophy and on issues in contemporary action theory and metaphysics.

All of the pieces advance our understanding of ancient Greek thought in important ways. College libraries should prize the book; it would also serve as an excellent text for graduate classes in ancient Greek philosophy. For scholars in logic and critical thinking, it would be a great asset to understanding how many contemporary issues have ancient precedents.
