The Western tradition of philosophy began in Greece with a cluster of thinkers often called the Presocratics, whose influence has been incalculable. All these thinkers are discussed in this volume both as individuals and collectively in chapters on rational theology, epistemology, psychology, rhetoric and relativism, justice, and poetics. Assuming no knowledge of Greek or prior knowledge of the subject, this volume provides new readers with the most convenient and accessible guide to early Greek philosophy available. Advanced students and specialists will find a conspectus of recent developments in the interpretation of early Greek thought.
