Oxford philosophy professor Will MacAskill joins us to talk about effective altruism, moral uncertainty, and why you shouldn’t eat your grandmother (even if consequentialism is true). How should we act when we’re not sure which moral theory is the right one? Can we formulate a guide for behavior, modeled on decision theory, that maximizes expected moral value? How do we assign credences to ethical (as opposed to empirical) claims? Why has effective altruism become so popular, so fast, yet at the same time seem off-putting to many people? Plus, Tamler faces a dilemma when narrating his audiobook, and Dave is the Louis CK of his own backyard.
