Le rapport politique-philosophie chez Sartre

Regarding the multiform Sartre’s work we often ask if he was a polygraph, in the manner of Prezzolini or of some intellectuals of the "tempo della Voce" of the early '900. Which was the true cultural identity of this Philosopher, novelist, playwright, essayist? Is it possible that the war in Algeria, the crisis of French colonialism, the Cold War, the May 1968 protest, could have led Sartre to try and tie the pluriform expressions of an "humanist" Existentialism with the tireless search for the roots of political economy and the material needs of humanity? Perhaps Sartre tries to bring his Existentialism as a key to find the real dimension of human subjectivity, to see the man in its constituent structures. Can man, the “Prométhée de l’échec", in this way have a real prospect of endless chances? Sartre "vivait pour écrire" - wrote Simone de Bouvoir - to give testimony to the roots of all political, social and institutional things
