125 - Bas van Fraassen: Realism, Thomas Kuhn, and the Semantic Approach in Philosophy of Science
Bas van Fraassen is the McCosh Professor of Philosophy Emeritus at Princeton University and a Distinguished Professor of Philosophy at San Francisco State University. In addition to being one of the most recognized philosophers of science working today—he received the Philosophy of Science Association’s inaugural Hempel Award—he has also worked in epistemology and logic. In this episode, Bas and Robinson discuss a major shift in the philosophy of science in the second half of the twentieth century from the view of the logical positivists, who had a formal, mathematical approach, to philosophers who adopted the semantic approach, which more closely aligned with how working scientists viewed and experienced the field. Some other issues touched on include scientific realism, Thomas Kuhn and The Structure of Scientific Revolutions, and interpretations of quantum mechanics.

123 - Paul Boghossian: The Sokal Hoax, The A Priori, and Moral Facts
Paul Boghossian is Silver Professor of Philosophy at New York University, where he is also Chair of the Philosophy Department. Paul has worked in a wide variety of areas within philosophy, including epistemology and the philosophy of language, mind, and logic respectively. Robinson and Paul discuss the sociological relationship between physics and philosophy, the Sokal Hoax, philosophy in public life, the role of the a priori and a posteriori distinction in metaphysics, logic, and epistemology, and the nature of moral facts.

118 - Slavoj Žižek & Sean Carroll: Quantum Physics, the Multiverse, and Time Travel
Slavoj Žižek is international director of the Birkbeck Institute for the Humanities at the University of London, visiting professor at New York University, and a senior researcher at the University of Ljubljana’s Department of Philosophy. He was also the guest for Robinson’s Podcast #109 on psychoanalysis, wokeness, racism, and a hundred other topics. Sean Carroll is Homewood Professor of Natural Philosophy at Johns Hopkins University and fractal faculty at the Santa Fe Institute. He is also host of Sean Carroll’s Mindscape, a terrific show (that influenced the birth of Robinson’s Podcast) about science, society, philosophy, culture, arts, and ideas. Sean was one of the guests—along with David Albert of Columbia—on Robinson’s Podcast #106, which covers the Many-Worlds theory of quantum mechanics, entropy and Boltzmann Brains, and the fine-tuned universe. In this episode, Robinson, Sean, and Slavoj (though mostly Sean and Slavoj) talk about quantum mechanics, the indeterminacy of small-scale reality, cosmology and the big bang, major figures like Niels Bohr, Einstein, and Stephen Hawking, and the world of sci-fi, including movies like Everything Everywhere All at Once, Indian Jones, and the Avengers.

117 - Anna Lembke: Dopamine, Drug Addiction, and Recovery
Dr. Anna Lembke received her undergraduate degree in Humanities from Yale University and and her medical degree from Stanford University. She is currently Professor and Medical Director of Addiction Medicine at the Stanford University School of Medicine. She is also Program Director of the Stanford Addiction Medicine Fellowship, and Chief of the Stanford Addiction Medicine Dual Diagnosis Clinic. In this episode, Robinson and Anna discuss her latest, New York Times bestselling book Dopamine Nation: Finding Balance in the Age of Indulgence (Dutton/Penguin Random House, August 2021). More particularly, they talk about just what happens in the brain when someone develops an addiction, what current social and cultural conditions have led to increased rates of addiction, and how all of these factors—and addiction itself—ought to be combatted. Anna is also the author of Drug Dealer, MD: How Doctors Were Duped, Patients Got Hooked, and Why It’s So Hard to Stop (Johns Hopkins, 2016), which sounded the alarm on—and covers—various dimensions of the opioid crisis.
