Most of us think it's obvious that we have a self, but famously, both Buddhism and British philosopher David Hume are skeptical that such a thing exists. What in the world could it mean to deny that the self exists? Could ‘the self' just refer to a series of perceptions and feelings we have over time? If so, then whose perceptions and feelings are they? Is there any way Buddhism could have influenced Hume's thinking on the illusory nature of the self? The philosophers question their selves with Alison Gopnik from UC Berkeley, author of The Philosophical Baby and "How David Hume Helped Me Solve My Midlife Crisis."

Throughout history, people have committed all kinds of cruel, degrading, and evil acts toward other people. Many believe that for evil acts like genocide to be even possible, the victims must first be dehumanized by the perpetrators, starting with dehumanizing language or propaganda. But is this lack of empathy always at the heart of human cruelty? When we call others “vermin,” “roaches,” or “animals” are we thereby denying their humanity? Or can human cruelty and violence sometimes rely on actually recognizing the other’s humanity? Josh and guest host Alison Gopnik welcome back Paul Bloom from Yale University, author of Against Empathy: The Case for Rational Compassion.
