Sartre, Nizan and Aron all met at school: Canguilhem joined them at the École Nationale Supérieur. Sartre, de Beauvoir and Merleau-Ponty were among Aron’s co-founders of the review ‘Les Temps modernes.’ Camus edited another journal, ‘Combat’, with him. He was taught by Alain (the pen-name of Émile Chartier), while Bourdieu became his teaching assistant. He worked briefly with Malraux; Arendt became a friend when she fled Nazi Germany. He said that if his fellow-student Cavaillès had survived, he (Aron) would not have committed so many errors.
