Stephen Hawking's proclamation that philosophy is dead was clearly hyperbole. But when it comes to understanding the fundamental nature of reality, has philosophy really got anything left to contribute? Does the rise of physics demand the end of metaphysics?
Debating these questions are:
Carlo Rovelli, Centre de Physique Théorique of the Aix-Marseille University
Eleanor Knox, King's College London
Alex Rosenberg, Duke University
Chair: Ritula Shah, BBC
