Jean-Paul Sartre was one of the first global public intellectuals, famous for his popular existentialist philosophy, his works of fiction, and his rivalry with Albert Camus.

How is man condemned to be free, as Sartre claimed? And what’s so hellish about other people? John and Ken speak in good faith with Thomas Flynn from Emory University, author of Sartre: A Philosophical Biography.
