242 - Victor Davis Hanson: President Donald J. Trump and the Fate of the United States

Raphael Bousso is the Chancellor’s Chair in Physics at the Berkeley Center for Theoretical Physics, where he leads the Bousso Group in research on quantum gravity and quantum information. He is a renowned string theorist famous also for his development of the string theoretic landscape and the Bousso bound in holography. In this episode, Robinson and Raphael talk about the foundations of quantum mechanics and whether or not there are any deep mysteries within the theory that remain to be solved, and whether philosophical discussion of these issues is overblown. More particularly, they get into what quantum theories tell us about the world, whether we need different interpretations of quantum mechanics, whether the final theory of the universe will be quantum mechanical, how quantum mechanics connects to cosmology, the multiverse, and quantum gravity, and more.

Robinson’s Podcast #240 - Peter Godfrey-Smith: Cuttlefish, Octopuses, and the Consciousness of Mysterious Minds Peter Godfrey-Smith is a professor in the School of History and Philosophy of Science at the University of Sydney. He has also taught at Stanford University and Harvard University. Among other topics, he has researched the philosophy of biology and mind, and is very well-known for his book Other Minds: The Octopus, The Sea, and the Deep Origins of Consciousness (FSG, 2016). In this episode, Peter and Robinson discuss that book, as well as his latest, Living on Earth (William Collins, 2024). More particularly, they discuss cuttlefish, octopuses, consciousness, metaethics, and animal welfare.

Barry Loewer is Distinguished Professor of Philosophy at Rutgers. Before that he did his PhD in philosophy at Stanford. Barry works largely in the philosophy of physics, the philosophy of science, and metaphysics. This is Barry’s third appearance on the show. He was last on episode 189 with David Albert, in which Robinson, David, and Barry discussed David and Barry’s joint program known as “The Mentaculus”, which they use to solve many problems in the foundations of physics, from probability to the direction of time. In this episode, Barry and Robinson discuss the philosophical foundations of science, touching on the relationship between science and pseudoscience, Karl Popper, string theory, scientific realism, and many other important debates and figures.
