The influence of Aristotle, the prince of philosophers, on the intellectual history of the West is second to none.

One of the leading philosophical movements of the 20th century, existentialism has had more impact on literature and the arts than any other school of thought.

With his well known idiosyncrasies and aphoristic style, Friedrich Nietzsche is always bracing and provocative, and temptingly easy to dip into. Michael Tanner's introduction to the philosopher's life and work examines the numerous ambiguities inherent in his writings and explodes many of the misconceptions that have grown in the hundred years since Nietzsche wrote "do not, above all, confound me with what I am not!"
