Blanchot studied philosophy at the University of Strasbourg, where he became a close friend of the Lithuanian-born French Jewish phenomenologist Emmanuel Levinas. He then embarked on a career as a political journalist in Paris. From 1932 to 1940 he was editor of the mainstream conservative daily the "Journal des débats". In 1930 he earned his DES (""), roughly equivalent to an M.A. at the University of Paris, with a thesis titled "La Conception du Dogmatisme chez les Sceptiques anciens d'après Sextus Empiricus" ("The Conception of Dogmatism in the Ancient Sceptics According to Sextus Empiricus").
