Abstract
Marc Crépon was born in Decize, Nièvre, in 1962. After high school, he chose a preparatory course at Lycée Condorcet and was inspired by one of his professors, Serge Boucheron, to turn towards moral and political disciplines of philosophy. After attending Ecole Normale Supérieure and receiving his agrégation (passing a high-ranking civil service exam), Marc Crépon taught philosophy at Nanterre University before moving to the USSR for two years. This extended stay abroad greatly influenced his pedagogical approach and philosophical reflections, in which he developed most of his ideas on relations between political and linguistic communities. His research focuses on components of linguistic communities in French and German philosophy from the 18th to the 20th centuries, and also on contemporary political and moral philosophy. His main subject is violence.
