David Chalmers on Consciousness, the Hard Problem, and Living in a Simulation

Sean Carroll's Mindscape · David Chalmers · 82 min

Why we chose this episode

David Chalmers coined the term 'the hard problem of consciousness,' and here he and Sean Carroll spend an unhurried hour testing where physicalist explanations of the mind actually break down. The conversation is rigorous without being dense, and it treats simulation theory seriously rather than as a gimmick. Few philosophy-of-mind conversations manage to be both this careful and this fun.
