1 - Haim Gaifman: Vagueness & the Sorites Paradox

Sophie Grace Chappell is Professor of Philosophy at the Open University in the UK. Before that she taught at the University of Dundee and Oxford. 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.

Richard Kimberly Heck has been a professor of philosophy at Brown University since 2005, at which time they left their post at Harvard, where they had taught for over a decade. On the way to receiving their PhD in philosophy and linguistics at MIT, they studied at Duke and Oxford. While Professor Heck’s primary research focus has been logic and Frege, over the past few years they have shifted to the philosophy of sex and pornography. This is Robinson and Riki’s third conversation on the subjects. Their first and second were episodes 5 and 17, though the installments are not sequential and only linked by topic. Among other things, Robinson and Riki discuss empirical approaches to the philosophy of sex, understanding oneself as a gendered person, and the depiction of oral sex in pornography.

L.A. Paul is the Millstone Family Professor of Philosophy and Professor of Cognitive Science at Yale University. After doing her graduate work on causation and time at Princeton under the guidance of David Lewis, Laurie wrote her groundbreaking book Transformative Experience, and since then has been exploring the intersection of cognitive science and metaphysics (in addition to a myriad of other pursuits). Laurie and Robinson talk about how she went from her undergraduate studies in chemistry and biology to philosophy, the origins of Transformative Experience, and what cognitive science can contribute to the philosophy of time and causation.

Paul B Woodruff is a professor in the philosophy department at the University of Texas at Austin. Over the course of his extensive career he’s published numerous books, articles, and translations covering areas ranging from ancient philosophy and Greek tragedy to ethics and aesthetics. In the years between completing his undergraduate work in classics at Princeton and then getting his PhD in philosophy at the same university, he served in the Vietnam War, and it is largely this experience and the philosophical thought that emerged from it which Robinson and Paul discuss. Along with other topics, they talk about the ethics of killing civilians, just war theory, and Socrates’ practical ethics.
