 If nothing is without a cause, can we ever have free will? Is consciousness just an illusion? Does evolution explain the way our minds work? Welcome to Philosophy Talk, the program that questions everything. Accept your intelligence. I'm Josh Landy. And I'm Rae Briggs. We're coming to you via the studios of KALW San Francisco Bay Area. Continuing conversations that begin at Philosopher's Corner on the Stanford campus, where Rae teaches philosophy and I direct the Philosophy and Literature Initiative.
