Jean-Paul Sartre is an undisputed giant of twentieth-century philosophy. His intellectual writings popularizing existentialism combined with his creative and artistic flair have made him a legend of French thought. His tumultuous personal life - so inextricably bound up with his philosophical thinking - is a fascinating tale of love and lust, drug abuse, high profile fallings-out and political and cultural rebellion. This substantial and meticulously researched biography is accessible, fast-paced, often amusing and at times deeply moving. Existentialism and Excess covers all the main events of Sartre's remarkable seventy-five-year life from his early years as a precocious brat devouring his grandfather's library, through his time as a brilliant student in Paris, his wilderness years as a provincial teacher-writer experimenting with mescaline, his World War II adventures as a POW and member of the resistance, his post-war politicization, his immense amphetamine fueled feats of writing productivity, his harem of women, his many travels and his final decline into blindness and old age. Cox deftly moves from these episodes to discussing his intellectual development, his famous feuds with Aron, Camus, and Merleau-Ponty, his encounters with other giant figures of his day: Roosevelt, Hemingway, Heidegger, John Huston, Mao, Castro, Che Guevara, Khrushchev and Tito, and, above all, his long, complex and creative relationship with Simone de Beauvoir.
