Daniel Dennett sits down with Jonathan Miller for the sixth and final installment of the interview series Miller built around his documentary on the history of disbelief. There is no narration, no reenactment, just two men talking, Miller drawing out the philosopher's path to atheism and the reasoning that keeps him there. Dennett works through his usual territory: the evolutionary roots of religious belief, why the human mind is so ready to find agency and intention behind natural events, and what he thinks that means for the truth claims of religion itself. Miller, a neurologist by training turned interviewer, presses him on specifics rather than letting the conversation stay abstract, so the exchange moves through argument and counterargument rather than settling into a monologue. Shot plainly, close on both faces, the film leans entirely on the content of what Dennett says. It closes out a set of six conversations that also included Richard Dawkins, Steven Weinberg, and Colin McGinn, each pressed the same way on how they arrived at disbelief.
