1 - Haim Gaifman: Vagueness & the Sorites Paradox

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. 00:00 In This Episode… 01:13 Introduction 04:16 Chris and Linguistics 12:34 Linguistics and Philosophy 22:43 Proper Names and Reference 27:00 The Principle of Compositionality 41:59 Adjectives, Innateness, and Chomsky 57:36 Quantifiers 01:01:36 Swearing and Linguistics 01:04:42 ChatGPT in the Linguistics Classroom 01:12:00 Does ChatGPT Understand?

Barry Loewer is Distinguished Professor of Philosophy at Rutgers. Before that he did his PhD in philosophy at Stanford (!). Barry works largely in the philosophy of physics, the philosophy of science, and metaphysics, and is a good friend of and frequent collaborator with another denizen of the Robinson’s Podcast universe, David Albert. It is their joint work on the “Mentaculus,” something approximating a “probability map of the universe,” that occupies much of the discussion in this episode. Robinson and Barry also talk about statistical mechanics and his upcoming book, What Breathes Fire into the Equations (Oxford University Press, to be released fall 2023 or early 2024), which is about laws, chances, and fundamental ontology. Check out Barry’s book on David: Essays on David Albert’s Time and Chance.

Jonathan Wolff is Alfred Landecker Professor of Values and Public Policy at the University of Oxford. He works in numerous areas of political philosophy. Some topics he has researched include equality and poverty, and he has worked in applied areas like Covid policy and gambling. In this episode, Jonathan and Robinson begin with a discussion of the nature of political philosophy before turning to some modern historical perspectives on the state, starting with Hobbes and traveling up through Marx and Rawls. They then turn to his current work in partnership with Avner de-Shalit on cities and equality. Some of Jonathan’s books include Disadvantage (Oxford, 2007), An Introduction to Political Philosophy (Oxford, 1996, and soon to be in its fourth edition), and Why Read Marx Today?

Anubav Vasudevan is Associate Professor in the Department of Philosophy at the University of Chicago, where he works in formal epistemology and the history of logic, though he has published in a number of other areas. Anubav and Robinson talk about his time at Columbia University studying with the mathematician, probability theorist, and philosopher Haim Gaifman before discussing some of Anubav’s thoughts on mathematics, physics, logic, and how they relate to philosophy. In the second half of the conversation they move on to some of Anubav’s work in the history of logic, touching on Leibniz and the Peripatetic school.

Pamela Hieronymi is Professor of Philosophy at UCLA. Before that, she did her undergraduate studies at Princeton and received her PhD from Harvard. Her work extends in a variety of directions, but some areas she works in include moral psychology, the philosophy of mind, ethics, and the philosophy of action. In this episode, she and Robinson discuss free will and moral responsibility, the topic of an upcoming book entitled Minds that Matter. Pamela begins by introducing moral psychology and the role of analytic philosophy in the debate over free will. Then she and Robinson discuss the extent to which we control our actions and thoughts, and how all of this relates to the question of moral responsibility. Pamela’s most recent book is Freedom, Resentment, and the Metaphysics of Morals (Princeton University Press, 2020).

Rachel Barney is Professor of Classics and Professor of Philosophy at the University of Toronto. She received her PhD at Princeton and has taught at the University of Ottawa, Harvard, and the University of Chicago. She has worked widely across ancient philosophy, from the sophists to the Neoplatonists, though her primary focus is on Plato. In this episode, Robinson and Rachel discuss the sophists, beginning with just who they were and why they have been so maligned in contemporary discourse—even the word sophist today has pejorative connotations—and continuing through some of their most important thinkers, like Gorgias and Protagoras. Check out Rachel’s last book, Plato and the Divided Self (Cambridge University Press, 2012).

Paul Horwich is Professor Philosophy at NYU. He has worked in a number of areas of philosophy, but is especially well-known for his writing on the philosophy of language, particularly with regard to truth and meaning—naturally, he has books by the same names, Truth (Oxford, 1990) and Meaning (Oxford, 1998). Robinson and Paul discuss the relationship between his work on these topics and the philosophy he started off researching—science and physics—before moving on to the question of philosophical realism across a number of domains before focusing on moral realism and whether there are such things as moral facts.  OUTLINE: 00:00 In This Episode... 00:20 Introduction 03:26 From Physics to Truth 16:55 Truth and the World 35:24 Realism Across Domains 54:42 Moral Facts Robinson’s Website: http://robinsonerhardt.com Robinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University.

Stephen Yablo is David W. Skinner Professor of Philosophy at MIT. Before MIT, he taught at the University of Michigan, Ann Arbor. Steve works in metaphysics, philosophy of mathematics, and the philosophy of mind and language, though his work extends into other areas of philosophy as well. In this conversation, for instance, Robinson and Steve discuss the nature of philosophy and what distinguishes it from other fields, as well as the philosophy of jokes and humor. They also speak about the philosophy of language, and more particularly how to deal with negative existential statements (sentences of the form “such-and-such does not exist”). Check out Steve’s latest book, Aboutness (Princeton, 2019), which develops a theory of subject matter and its role in meaning.
