A full account of the philosophy of the Greek and Roman worlds from the last days of Aristotle (c. 320 BC) until 100 BC. Hellenistic philosophy, for long relatively neglected and unappreciated, has over the last decade been the object of a considerable amount of scholarly attention. Now available in paperback, this volume is the first general reference work to pull the subject together and present an overview. The time has come for a general reference work which pulls the subject together and presents an overview. The History is organised by subject, rather than chronologically or by philosophical school, with sections on logic, epistemology, physics and metaphysics, ethics and politics. It has been written by specialists but is intended to be a source of reference for any student of ancient philosophy, for students of classical antiquity and for students of the philosophy of later periods. Greek and Latin are used sparingly and always translated in the main text.
