To kick off the new season of 15 Minute History, we talk to Yoav di-Capua, a Professor of History at the University of Texas at Austin and the author of “No Exit Arab Existentialism, Jean-Paul Sartre, and Decolonization.” Professor di-Capua talks about French philosopher Jean-Paul Sartre’s 1967 trip to Egypt and Israel on a quest to understand the region and its conflicts. The trip would challenge and change him — and lead to accusations of betrayal.
