157 - David Albert: The Metaphysics of Quantum Mechanics

David Albert is the Frederick E. Woodbridge Professor of Philosophy at Columbia University and one of the world’s most respected philosophers of physics. He is also the director of the Philosophical Foundations of Physics program at Columbia and a faculty member of the John Bell Institute for the Foundations of Physics. This is David’s fifth (!) appearance on Robinson’s Podcast. He appeared on episode #23 with Justin Clarke-Doane on metaethics and absolute space, episode #30 on the philosophy of time, episode #67 with Tim Maudlin on the foundations of quantum theory, and episode #106 with Sean Carroll on Many-Worlds and fine-tuning. In this episode, Robinson and David discuss his new book, A Guess at the Riddle: Essays on the Physical Underpinnings of Quantum Mechanics (Harvard, 2023), and the metaphysics of quantum mechanics.
