The first edition of the Cambridge Companion to Plato (1992), edited by Richard Kraut, shaped scholarly research and guided new students for thirty years. This new edition introduces students to fresh approaches to Platonic dialogues while advancing the next generation of research. Of its seventeen chapters, nine are entirely new, written by a new generation of scholars. Six others have been thoroughly revised and updated by their original authors. The volume covers the full range of Plato's interests, including ethics, political philosophy, epistemology, metaphysics, aesthetics, religion, mathematics, and psychology. Plato's dialogues are approached as unified works and considered within their intellectual context, and the revised introduction suggests a way of reading the dialogues that attends to the differences between them while also tracing their interrelations. The result is a rich and wide-ranging volume which will be valuable for all students and scholars of Plato. ‘Without question, the second edition of this companion is a welcome addition to Plato scholarship … These essays illuminate specific aspects of his work within its coherent overall corpus. Including a historical chronology, a 32-page bibliography, extensive chapter notes, and a general index and index locorum, this volume will be an enduring resource … Essential.’ J. Gough, Choice A rich and wide-ranging Companion to Plato's philosophy that is accessible to students while of equal interest to scholars. David Ebrey is Researcher at Humboldt-Universität zu Berlin.
