Gabriel Greenberg is a professor of philosophy at the University of California Los Angeles, and currently a visiting professor at Stanford University. He works widely across the philosophy of mind, but in particular studies iconic representation, modality, and computation. Gabe and Robinson talk about the rough divide between representation and consciousness studies in the philosophy of mind before going into the distinction between signs and symbols, and how the brain interprets them. They finish with a departure into the world of philosophy, film, and cognitive science, discussing how our minds stitch together the scenes of a movie and integrate them into a whole. linktree: https://linktr.ee/robinsonerhardt Outline: 00:00 In This Episode 00:39 Introduction 5:17 Gabe’s Taste in Comics 9:53 Gabe’s Interest in Philosophy of Mind 18:14 What is a Representation? 26:02 Gabe’s Dialogue with Linguistics 27:51 Aboutness in the Philosophy of Mind 34:21 The Iconic-Symbolic Spectrum 59:48 A Semantics for Signs and Icons 1:09:33 A Course on Visual Narrative 1:11:20 Film and The Norms of Spatial Coherence 1:15:43 Film Spaces as Abstract Spatial Graphs 1:46:20 Film, Semantics, and Pragmatics 1:51:38 On Scott McCloud Robinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University.

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.

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.
