Description: This book is one of the great works of Western philosophy. Even today, writings on moral virtues such as courage and justice draw inspiration from this work, which also contains important insights into responsibility, practical reasoning, and on the role of friendship in creating the best life. This new edition combines David Ross's classic translation, lightly revised by Lesley Brown, with an invaluable introduction and explanatory notes. A glossary of key terms and comprehensive index, as well as a fully updated bibliography, add further value to this new edition.
