The University Press of France and Fremeaux & Associes offer a special course on the history of philosophy, given here by Pierre Guenancia, professor at the University of Burgundy and specialist in the history of modern philosophy. After a first course, “De Descartes a Hume,” we are pursuing now a new path taken by contemporary philosophy at the end of the 19th century, the “way of consciousness.” Philosophy does not want to be a philosophical system anymore, rather, its ambition is to return things to themselves and describe the phenomena such as they give themselves to consciousness. Husserl opened the way to Sartre, Merleau-Ponty, and Ricoeur, the great figures of the twentieth century philosophy that Pierre Guenancia presents to us in this release.
