Cognitive Depths: Encounters with Cuttlefish

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.
