This collection introduces readers to some of the most respected Pre-Socratic scholarship of the twentieth century. It includes translations of important works from European scholars that were previously unavailable in English and incorporates the major topics and approaches of contemporary scholarship. Here is an essential book for students and scholars alike. "Students of the Pre-Socratics must be grateful to Mourelatos and his publishers for making these essays available to a wider public."--T. H. Irwin, American Journal of Philology "Mourelatos is a superb editor, and teaching Pre-Socratics in the future with this collection on the reading list will not only be easier but also better."--Jorgen Mejer, The Classical World "The editor has done his work judiciously. It would be difficult to devise a better balance between different parts of the subject."--Edward Hussey, Archives internationales d'histoire des sciences "[This book] will undoubtedly become an indispensable aid for beginning and advanced students of the Pre-Socratics."--David E. Hahm, Isis Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
