In them, Castoriadis goes to the heart of deep philosophical issues raised but not answered by modern thought.The book presents his concerns with the development of analytical theories of psychology, language, and politics, all commonly rooted in the social and historical aspects of human creativity. It examines figures as diverse as Aristotle, Heidegger, Lacan, Marx, and Merleau-Ponty.Cornelius Castoriadis was for a long time a professional economist and is now a practicing psychoanalyst in Paris. He founded and became the main theoretician for the independent journal of the left, Socialisme ou Barbarie.
