Abstract: Abraham Robinson is well-known as the inventor of nonstandard analysis, which uses nonstandard models to give the notions of infinitesimal and infinitely large magnitudes a precise interpretation. Less discussed, although subtle and original—if ultimately flawed—is Robinson’s work in the philosophy of mathematics. The foundational position he inherited from David Hilbert undermines not only the use of nonstandard analysis, but also Robinson’s considerable corpus of pre-logic contributions to the field in such diverse areas as differential equations and aeronautics. This tension emerges from Robinson’s disbelief in the existence of infinite totalities (any mention of them is ‘literally meaningless’) and the fact that much of his work involves them. I argue that he treats infinitary avenues of mathematics as useful tools to avoid this difficulty, but that this is not successful to the extent that these tools must be justified by a conservative extension from finitary mathematics. While Robinson provides a compelling and unorthodox pragmatic justification for the role of formal systems in mathematical practice despite their apparent infinitary presuppositions, he deflates mainstream mathematics to a collection of games that occasionally produces meaningful results. This amounts to giving up on a commitment to reconciling his finitism with his mathematical practice.

Deborah Gordon is Professor of Biology at Stanford University. She is a myrmecologist—an entomologist who studies ants—focusing on how complex behavior emerges from ant colonies, which have no central control. In this episode, Deborah and Robinson discuss some of the distinctive features of ants, how pheromones help to determine their behavior, examples of fascinating ant species, collective ant behavior, and the life cycle of an ant colony. For more of Deborah’s work on collective behavior, check out her book The Ecology of Collective Behavior (Princeton, 2023).

In this episode, Robinson and Victor discuss his latest book, The End of Everything: How Wars Descend into Annihilation (Basic Book, 2024), which was released on May 7th. More particularly, they cover the historical connection between annihilation and genocide, how we should interpret the past through today’s moral standards, genocides in the present, and the likelihood of World War III. Victor appeared as a guest on episode #112, in which he and Robinson talked about what was at the time Victor’s latest book, The Dying Citizen. He was also a guest on episode #191, which covered Victor’s views on the current crisis in Israel and Palestine. Keep up with Victor on Twitter, through his website, and on his podcast, The Victor Davis Hanson Show.

He appeared with David Albert of Columbia University on episode 106, which covers the Many-Worlds theory of quantum mechanics, Boltzmann Brains, and the fine-tuned universe. He was also on episode 118 with Slavoj Žižek on quantum physics, the multiverse, time travel, and a whole lot more, and then episode 200 with Daniel Dennett and Steven Pinker on AI, parapsychology, and consciousness. This episode is coming out in advance of Sean’s next book, Quanta and Fields: The Biggest Ideas in the Universe (Penguin, 2024), which will be released on May 14, 2024. Sean and Robinson discuss many of the topics and themes of Quanta and Fields, including the books’ namesake subjects, as well as more decides, like scientific realism, free will, the simulation hypothesis, and the end of physics.
