Available in paperback for the first time, this landmark volume examines the course of Western philosophy over the past 2,500 years, focusing on the most signifigant thinkers and philosophical movements while emphasizing key ideas of permanent interest and relevance. The contributors - many of them outstanding contemporary philosophers representing a wide range of philosophical views, such as A.P. Cavendish, Arthur Danto, J.N. Indlay, and Alasdair MacIntyre - lucidly and succinctly explain principal concepts and theories and evaluate them in light of today's knowledge. Arranged chronologically from early Greece to the twentieth century, this comprehensive work includes expert histories of all major figures from Socrates and Plato to G.E. Moore and Bertrand Russell, and of every important school from the Epicureans to the Existentialists. With a fully updated bibliography.
