This 7th Edition of Philosophic Classics, Volume I: Ancient Philosophy includes essential writings of the most important Greek philosophers, along with selections from some of their Roman followers. In updating this edition, editor Forrest E. Baird has continued to follow the same criteria established by the late-Walter Kaufmann when the Philosophic Classics series was first established: (1) to use complete works or, where more appropriate, complete sections of works (2) in clear translations (3) of texts central to the thinker's philosophy or widely accepted as part of the "canon." To make the works more accessible to students, most footnotes treating textual matters (variant readings, etc.) have been omitted and important Greek words have been transliterated and put in angle brackets. In addition, each thinker is introduced by a brief essay composed of three sections: (1) biographical (a glimpse of the life), (2) philosophical (a resume of the philosopher's thought), and (3) bibliographical (suggestions for further reading).
