The war permanently ruptured Sartre’s philosophical kinship with Heidegger

Evidence

After his return, he marvelled to Beauvoir at how Heidegger was revered these days: ‘Four thousand students and professors toiling over Heidegger day after day, just think of it!’ From then on, he referred to Heidegger dismissively as the Old Man of the Mountain. The days had long passed when Sartre had seized on Being and Time as his only consolation during the days after France’s defeat in 1940. But Sartre was not the only one who could not go backwards. The war had changed everything, for everyone. — Sarah Bakewell, At the Existentialist Café, 662
