Freedom was the central problem and preoccupation of French existentialism – not only of its central figure, Jean-Paul Sartre, but also of his sometime intellectual friend and rival, Maurice Merleau-Ponty. They had in common what they inherited from their immediate German predecessors – from Edmund Husserl a commitment to phenomenology as a method of inquiry, from Martin Heidegger a conviction that traditional philosophy had failed to take seriously the existential sources of its own questions and concepts. Like Husserl and Heidegger, they were critics of theoretical abstraction and scholastic refinement, champions of the concrete, eager to remind philosophical reflection of its groundedness in what Sartre called the “pre-reflective cogito” (cogito préréflexif), or as Merleau-Ponty said, translating literally from the German Erlebnis, “lived experience” (l’expérience vécue).1
