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. If you’re interested in the foundations of physics, then please check out the the John Bell Institute for the Foundations of Physics, which is devoted to providing a home for research and education in this important area. Any donations are immensely helpful at this early stage in the institute’s life.
