Emmanuel Levinas is now widely recognized alongside Heidegger, Merleau-Ponty and Sartre as one of the most important Continental philosophers of the twentieth century. His abiding concern was the primacy of the ethical relation to the other person and his central thesis was that ethics is first philosophy. His work has had a profound impact on a number of fields outside philosophy—such as theology, Jewish studies, literature and cultural theory, psychotherapy, sociology, political theory, international relations theory and critical legal theory.
