The well known French existentialist was a Marxist and an admirer of the USSR. He was willing to tolerate some problems believing it would eventually develop into some kind of ideal society. It was only when the USSR invaded Hungary that he lost his "faith". He remained a "Marxist" until his death but was vague about how such a society would actually function. His best known work is "Being and Nothingness" which comports to my personal view of the content of his work. Then again, who am I to challenge the great philosopher? Given that he somehow slept through the late 1930s but woke up in 1956 (at least partially), why should I respect this man''s work. What would Sartre think of Cuba, Nicaragua or Venezuela today.
