Abstract
In this paper Giuseppe Bianco analyzes the ideological and epistemological coordinates and the space of possibilities proper to the cluster of philosophy students of which Tournier was part between 1943 and 1948; to do so he reconstructs their evolution in a context dominated by the currents of Neo-Scholasticism, Personalism, phenomenology, Marxism, and Existentialism. Finally, he focuses on the importance of Jean-Paul Sartre for these young people, underlining their particular interpretation of his work.
