Three friends with four philosophy degrees between them sit down to discuss what it means to think philosophically. Why is philosophy so important? How do you learn to think philosophically? Philosophy is concerned with three basic questions: "What is there?," "How do I know about it?," and "What do I do about it?" The three questions correspond to the fields of metaphysics, epistemology, and ethics. Our Cato colleague Matthew Feeney joins us this week to talk about philosophy, rhetoric, why people disagree about politics, performative morality, the non-aggression axiom, and more.
