Ludwig Wittgenstein lived a life of tortured genius - spending periods in extreme isolation in a hut in Norway and a cottage on the Atlantic coast of Ireland - but he claimed to have solved the problem of philosophy once and for all. Surprisingly, he then went on to create a second philosophy. His compelling character was matched by the pellucid profundity of his philosophical remarks. 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.
