93 - Havi Carel: The Phenomenology of Illness
Havi Carel is Professor of Philosophy at the University of Bristol, where she studies illness and its relationship to philosophy. Her research draws largely on phenomenology, a philosophical approach most closely associated with the Continental tradition of philosophy, and that relies heavily on perception and experience. In this episode Robinson and Havi discuss her own illness, LAM, and how it affects her own work, along with many other topics related to illness, such as Freud, mental health, and breathlessness.

92 - Joan Bagaria: What Is Set Theory?
Joan Bagaria is ICREA Research Professor in the Department of Experimental Sciences and Mathematics at the University of Barcelona. He is a mathematical logician who works in set theory, which is the branch of mathematics that not only specializes in the investigation of infinity but serves as the foundation for the rest of mathematics—what this means, and its implications, are explored in the episode. Joan and Robinson discuss all things set theory, beginning with its origins in the mind of Georg Cantor, its development in the 20th century, some philosophical questions, and some current outstanding problems. They also briefly touch on Catalan independence, a topic dear to Joan’s heart.

88 - Graham Oppy: Ontological Arguments and the Existence of God
Graham Oppy is Professor of Philosophy at Monash University. Before that, he did his undergraduate work in Melbourne and his graduate work at Princeton. Though Graham is best known as a philosopher of religion, he has also published on the philosophy of math, language, aesthetics, and more. In this episode, Robinson and Graham begin by discussing the nature of argument: What makes an argument successful? What’s a good argument? How should we think about arguments in areas of deep disagreement? They then move on to a discussion of ontological arguments in the philosophy of religion, where one argues for the existence of god—or gods—without any prior assumptions.

87 - Frank Jackson & Graham Priest: The Philosophy of David Lewis
Frank Jackson is Emeritus Professor at the Australian National University. He is best known for the knowledge argument and Mary’s Room—its accompanying thought experiment—but has published widely in the philosophy of mind, epistemology, metaphysics, and the philosophy of language. Graham Priest is a Distinguished Professor in the philosophy department at the CUNY Graduate Center. Like Frank, he is one of the most influential philosophers of the past fifty years, and has done important work on a wide range of topics, ranging from the philosophy of mathematics to logic and eastern philosophy. In this episode, Robinson, Frank, and Graham talk about David Lewis and his immense legacy in the philosophical world. They cover his character—Frank and Graham were friends with him for many years—as well as some of his work, ranging from the thesis of modal realism to Humean supervenience and the philosophy of set theory.

85 - Ernest Lepore: Linguistic Conventions, Slurs, and Philosophy of Language
Ernest Lepore is a Board of Governors Professor of Philosophy at Rutgers. Though Ernie is best known for his work in the philosophy of language, he has also published on philosophical logic, metaphysics, and the philosophy of mind. Though Robinson and Ernie largely discuss the former, their conversation begins with a bevy of wonderful stories from the profession, as Ernie worked and studied with many of the greatest thinkers—and characters—of twentieth century philosophy, including Ed Gettier, Jerry Fodor, Donald Davidson, Michael Dummett, and W.V.O. Quine. They then turn to some quite general problems in the philosophy language, discussion the relationship between language and thought, meta-linguistic negotiation, and conventions before going through the main arc of his book on slurs jointly authored with Una Stojnic of Princeton University. Though Ernie is the author of too many books and articles to list within the confines of this description, a recent book mentioned many times in the conversation is Imagination and Convention: Distinguishing Grammar and Inference in Language (Oxford University Press, 2015), which Ernie cowrote with Mathew Stone, chair of the Department of Computer Science at Rutgers.

Chris Potts is Professor and Chair of the Department of Linguistics at Stanford University, and also Professor by courtesy in the Department of Computer Science at the same. Chris has worked on a wide variety of topics in linguistics throughout his career, but has published on conventional implicature—check out his book, Logic of Conventional Implicatures (Oxford, 2003)—large language models, and compositional reasoning, among many other subjects. Robinson and Chris begin by discussing the relationship between linguistics and philosophy before turning to topics in semantics and pragmatics—references, the principle of compositionality, swearing, and more. After some thoughts on Chomsky’s legacy in linguistics, they talk about the impact of ChatGPT on the classroom and whether large language models are capable of understanding.
