The French philosopher Foucault was arguably the most controversial of modern thinkers. His lifestyle was unorthodox and his ideas on power, history, knowledge and sexuality challengend many previously held views. Opinions differ as to his true standing: to many he was a hero of modern thought; to others his ideas were pernicious and overrated. This series of guides cover the lives and ideas of the major philosophers. The author's concise and comprehensible style highlights the major advances in philosophy, as well as the men who conceived them and the times in which they lived. Containing quotes, insights and anecdotes, the aim of this series is to clarify the mysteries of philosophy for the general reader.
