In this episode, Xavier Bonilla has a dialogue with Richard Polt about the philosophy of Martin Heidegger. They define and discuss Dasein, 3 forms of Dasein, and how it is different from other types of being. They talk about authenticity and inauthenticity, being as metaphysics, and the role of Aristotle's philosophy on Heidegger's thought. They discuss Heidegger's "turn" in the 1930s, being-in-the-world, 4 senses of the world, and what a shared world means. They also talk about environment, present-at-hand, and ready-to-hand. They engage on Heidegger's concepts of care, thrownness, and anxiety. They also mention Heidegger's thoughts on language and technology, along with his involvement in the Nazi party, and many other topics.
