Luc Ferry is a major philosopher of our times. Also known for his political action (he was the minister for Education between 2002 and 2004), Luc Ferry has a great career as a writer and as a teacher. These skills enable him to deliver an amazingly clear-to-understand speech, exclusively recorded in studio for FrEmeaux & AssociEs, in various set devoted to a great philosopher (Kant, Nietzsche). In this new release, Luc Ferry has chosen a different approach and explains the philosophical background of Christianity. Not as a believer, but in order to understand the evolution compared to the Greeks, and the basis of our societies. In French.
