This is a completely new translation of one of the great works of Western political thought. In addition to Tom Griffith's vivid, dignified and accurate rendition of Plato's text, this edition is suitable for students at all levels. It contains an introduction that assesses the cultural background to the Republic, its place within political philosophy, and its general argument; succinct notes in the text; an analytical summary of content; a full glossary of proper names; a chronology of important events; and a guide to further reading.
