Soon after its publication, Readings in Ancient Greek Philosophy was hailed as the favorite to become the 'standard' text for survey courses in ancient philosophy. Nothing on the market touches it for comprehensiveness, accuracy, and readability.* (*APA Newsletter on Teaching Philosophy). Fifteen years on, that prediction has been borne out, and the volume's preeminence as the leading anthology for the teaching of ancient philosophy still stands.The Fourth Edition features a completely revamped and expanded unit on the Presocratics and Sophists that draws on the wealth of new scholarship published on these fascinating thinkers over the past decade or more. At the core of this unit, as ever, are the fragments themselves--but now in thoroughly revised and, in some cases, new translations by Richard McKirahan and Patricia Curd, among them those of the recently published Derveni Papyrus.
