Robinson's Podcast

Scott Shapiro is the Charles F. Southmayd Professor of Law and Professor of Philosophy at Yale Law School, where he is also the founding director of the Yale CyberSecurity Lab. Robinson and Scott talk about studying at Columbia University under the auspices of the legendary Isaac Levi, Sidney Morgenbesser, and Haim Gaifman before discussing the philosophy of law, one of Scott’s areas of expertise. Among the topics they touch on are the distinction between analytic and normative jurisprudence, the problem of the chicken and the egg, and progress in legal thought from Austin to Hart and beyond. Then they turn to Scott’s upcoming book, Fancy Bear goes Phishing: The Dark History of the Information Age, in Five Extraordinary Hacks, where Scott explores the intersection of cybersecurity, hacking, and legal philosophy. Scott is also the author of Legality and the host of the Jurisprudence Course podcast, the latter of which will soon have a second season. You can keep up with Scott on Twitter at @scottjshapiro, and preorder Fancy Bear Goes Phishing on Amazon.

Jonathan Schaffer is a Distinguished Professor in the Department of Philosophy at Rutgers University. He is an acclaimed metaphysician with a unique mind and approach to philosophy (and who has exquisite taste in epigraphs). Jonathan is best known for his work on monism, in which he contends that the cosmos is the lone fundamental object in reality, and on the grounding relation. He and Robinson begin by exploring monism, including its relationship to contemporary developments in physics, and then move on to the grounding relation, explicating just what this is and how it marks a departure from the dominant Quinean view of metaphysics. linktree: https://linktr.ee/robinsonerhardt Outline: 00:00 In This Episode 1:07 Introduction 4:54 Jonathan’s Epigraphs 10:02 What Is a Monist? 14:11 How Jonathan Became a Monist 17:06 Breeds of Monism 24:09 Mereological Nihilism 39:14 Have Jonathan’s Views Shifted Over The Years? 41:25 The Ontological Priority of the Whole 48:16 Monism and Quantum Entanglement 54:42 Occam’s Laser 59:40 Modal Considerations for Monism 1:03:17 Jonathan’s Interest in Grounding 1:06:33 Quinean Metaphysics and Grounding 1:15:22 The Aristotelian View of Metaphysics 1:18:21 Carnap and Grounding 1:21:33 What Grounds What? 1:26:32 Debunking Metaphysical Intuitions With Cognitive Science 1:39:38 Ground Functionalism 1:48:58 Grounding in Feminist Metaphysics 1:55:30 Jonathan’s Philosophical Program Robinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University.

Stephen Darwall is Andrew Downey Orrick Professor of Philosophy at Yale University and John Dewey Distinguished University Professor Emeritus at the University of Michigan. He is a world-renowned moral philosopher who has worked broadly across the ethical landscape, making important contributions to Kant scholarship, legal philosophy, deontology, and countless other areas. Steve and Robinson discuss the history of modern ethics, beginning with Hugo Grotius and traveling up through Hobbes, Hume, Kant, Bentham, and Smith before ending with Marx, Kierkegaard, and Nietzsche’s attack on morality.

Patricia Churchland is UC President’s Professor of Philosophy Emerita at the University of California, San Diego. She is among the most well-known and impactful figures working in the philosophy of mind, and a prominent early neurophilosopher who advocated the importance of neuroscience in the philosophy of mind. Pat and Robinson discuss three broad topics: neurophilosophy and ethics—particularly with reference to two of her recent books, Braintrust: What Neuroscience Tells Us about Morality and Conscience: The Origins of Moral Intuition—what neuroscience has to say about the problem of free will, and the neurophilosophical approach to consciousness. You can keep up with Pat’s work at patriciachurchland.com, as well as on Twitter, @patchurchland.

Achille Varzi is the John Dewey Professor of Philosophy at Columbia University and Bruno Kessler Honorary Professor at the University of Trento. He is a world-renowned metaphysicist and logician, and widely regarded as the greatest living mereologist. Yet despite all this Robinson asks Achille about his sleep habits, though afterward they discuss some more important philosophical questions: What is ontology? What is metaphysics, and how is it different from physics? After some tangents on nominalism and truthmakers, the conversation ends with a reflection on some of the late Saul Kripke’s contributions to philosophy.

Tim Maudlin is Professor of Philosophy at NYU. Before that, he did his undergraduate work in philosophy and physics at Yale and received his PHD from Pittsburgh in the History and Philosophy of Science. Tim is renowned as one of the leading philosophers of physics, and he also works in the philosophy of science and metaphysics. Among other things, Robinson and Tim talk about whether metaphysics should come prior to or after physics, the debates over absolute time and space, free will, the nature of physical laws, and David Lewis’s views on the Humean supermosaic.

Jody Azzouni is a professor of philosophy at Tufts University. While Jody is best known for his nominalist stance in the philosophy of mathematics, he is also an author of fiction, non-fiction, and poetry. He and Robinson talk about his love of writing and how his interest in mathematics bloomed during in his time spent at NYU and CUNY. They then move on to the debate between nominalists and platonists in the philosophy of mathematics, Jody’s own deflationary stance, and some adjacent concerns about ontological commitment in both formal and informal languages.

Sophie has a wide variety of interests, including ancient philosophy, ethics, and the philosophy of literature. She and Robinson speak about her latest book, Epiphanies: An Ethics of Experience. More particularly, their discussion centers around philosophy and literature—including a wonderful reading of Gerard Manley Hopkins—the relationship between ethics and aesthetics, and some potential pitfalls of taking a theory-building approach to moral philosophy.

Eric Schwitzgebel is a Professor of Philosophy at the University of California Riverside. Before that, he did his undergraduate work at Stanford, and then received his doctorate from the University of California Berkeley. Eric has worked on an extremely wide array of topics, ranging from Chinese philosophy to philosophy of mind, metaphilosophy, and metaphysics. In this conversation, however, Robinson and Eric talk about his upcoming book on philosophy and weirdness. In particular, they discuss why the United States might be conscious, what Kant and cyberpunk have in common, the moral value of alien microbes, and a lot more about garden snails than you thought you could ever find interesting. Keep up with Eric through his blog, the Splintered Mind, or on Twitter @eschwitz.

Joel David Hamkins is the O’Hara Professor of Philosophy and Mathematics at the University of Notre Dame, where he recently moved from the University of Oxford. Joel is one of the leading set theorists and philosophers of mathematics in the world, and he and Robinson discuss a lot—Hilbert’s Hotel, the continuum hypothesis, the set-theoretic multiverse, and even Joel’s dapper hat collection—but the main subject is his upcoming book, The Book of the Infinite, which is an accessible text on paradoxes and infinity. Joel has made the novel move of serializing it on Substack, so you can participate in its creation by checking out the link below, and otherwise see what he’s thinking about and working on through Twitter, MathOverflow, and his blog. The conversation grows technical from 1:10:26-2:00:25, but for those to whom that doesn’t appeal there are timestamps to navigate around this portion of the show.
