Philosophy is one of the most intimidating and difficult of disciplines, as any of its students can attest. This book is an important entry in a distinctive new series from Routledge: The Great Philosophers. Breaking down obstacles to understanding the ideas of history's greatest thinkers, these brief, accessible, and affordable volumes offer essential introductions to the great philosophers of the Western tradition from Plato to Wittgenstein. In just 64 pages, each author, a specialist on his subject, places the philosopher and his ideas into historical perspective. Each volume explains, in simple terms, the basic concepts, enriching the narrative through the effective use of biographical detail. And instead of attempting to explain the philosopher's entire intellectual history, which can be daunting, this series takes one central theme in each philosopher's work, using it to unfold the philosopher's thoughts.
