This early work on Greek philosophy is both expensive and hard to find in its first edition. It contains details on the development of philosophy from Thales to Plato. This is a fascinating work and thoroughly recommended for anyone interested in the history of philosophy. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
