Do we truly have free will, or are our choices determined by biology, upbringing and brain chemistry? In this episode of Unbelievable?, John Nelson hosts a lively philosophical dialogue between Joe Folley, host of Unsolicited Advice, and Dr Nathan Hawkins, a Christian philosopher who teaches at Cambridge. Together they explore libertarian free will, compatibilism and determinism, asking whether neuroscience has disproved human freedom, whether our thoughts are “just brain states”, and whether moral responsibility survives if forces beyond our control shape our choices. Along the way, they discuss Sam Harris, Robert Sapolsky, Alex O’Connor, Libet experiments, Peter Tse, moral blame, racism, brain tumours, pragmatism, idealism and the mystery of human agency. A thoughtful, accessible deep dive into freedom, responsibility and the self.
