This best-selling dictionary is written by one of the most famous philosophers of our time, and widely recognised as the best dictionary of its kind. Wide-ranging and authoritative, it covers every aspect of philosophy from Aristotle to Zen. Clear, concise and easy to use, it provides lively and accessible coverage of not only Western philosophical traditions, but also themes from Chinese, Indian, Islamic, and Jewish philosophy. Entries include over 500 biographies of famous and influential philosophers, in-depth analysis of philosophical terms and concepts, and a chronology of philosophical events stretching from 10,000 BC to the present day. The first edition of this dictionary became a market leader and a standard work of reference, selling over 100,000 copies. Now the author, Professor Simon Blackburn, has revised and updated it to include over 500 new entries including terms from related disciplines such as religion, science and logic. Fully cross-referenced and containing over 3,000 alphabetical entries, this dictionary is the ideal introduction to philosophy for beginners, and an essential work of reference for more advanced students and teachers.
