Peter Singer is one of the world’s most influential living philosophers, whose ideas have motivated millions of people to change how they eat, how they give, and how they interact with each other and the natural world. Peter joined Tyler to discuss whether utilitarianism is only tractable at the margin, how Peter thinks about the meat-eater problem, why he might side with aliens over humans, at what margins he would police nature, the utilitarian approach to secularism and abortion, what he’s learned producing the Journal of Controversial Ideas, what he’d change about the current Effective Altruism movement, where Derek Parfit went wrong, to what extent we should respect the wishes of the dead, why professional philosophy is so boring, his advice on how to enjoy our lives, what he’ll be doing after retiring from teaching, and more.
