For this edition, Jonathan Barnes has brought together the surviving Pre-Socratic fragments in their original contexts, utilizing the latest research and a recently discovered papyrus of EmpedoclesAlso includes synopsis, note to the reader, appendix on sources, subject index, and index on sourceHis introduction provides a reassessment of this group of fascinating men and discusses the ways in which these ancient works remain profoundly relevant todayUseful text for students of philosophy or ancient historyJonathan Barnes is Professor of Ancient Philosophy at the University of Geneva. He has held visiting posts at the University of Chicago, at the Institute for Advanced Study in Princeton, at the University of Massachusetts in Amherst and at the University of Texas. He was also a fellow of Oriel College, Oxford. His publications include The Cambridge Companion to Aristotle (1995), and The PreSocreatic Philosophers (1979).The works collected in this volume form the true foundation of Western philosophy - the base upon which Plato and Aristotle and their successors would eventually build. Yet the importance of the Pre-Socratics thinkers lies less in their influence - great though that was - than in their astonishing intellectual ambition and imaginative reach. Zeno's dizzying 'proofs' that motion is impossible; the extraordinary atomic theories of Democritus; the haunting and enigmatic epigrams of Heraclitus; and the maxims of Alcmaeon: fragmentary as they often are, the thoughts of these philosophers seem strikingly modern in their concern to forge a truly scientific vocabulary and way of reasoning.
