An individual "is responsible for everything he does," claimed Sartre. And from criminal justice to creative expression, free will and responsibility are central to our culture and our personal lives. Yet neuroscientists and materialist thinkers commonly maintain that freedom is an illusion. Hosted by Hilary Lawson, Paul Bloom, Robert Sapolsky and Lucy Allais ask: can these two ideas co-exist?

Hilary Lawson joins the BBC's Moral Maze to interrogate the perennial question, 'What Is Truth?'. Aired 24 December 2025, on BBC Radio 4.

In conversation with Robert Lawrence Kuhn, Hilary Lawson discusses his book, 'Closure: A Story of Everything', a text that develops a comprehensive system of non-realist metaphysics.
