Long neglected and unappreciated, the philosophy of the Greek and Roman worlds--from the last days of Aristotle (c. 320 BC) until 100 B.C.--has over the last decade received a considerable amount of renewed scholarly attention. This history is organized by subject, rather than chronologically or by philosophical school, with sections on logic, epistemology, physics and metaphysics, ethics and politics. Written by specialists, it is intended to be a reference for any student of ancient philosophy. Greek and Latin are used sparingly and always translated in the main text.
