Robinson's Podcast

Ned Block is Silver Professor at New York University in the Departments of Philosophy and Psychology, where he works on the philosophy of mind, the philosophy of neuroscience, and cognitive science. In this episode, Robinson and Ned discuss some of the titans he studied under, ChatGPT and the nature of artificial intelligence, the Turing Test, androids, consciousness, the connection between seeing and thinking, blindsight, change blindness, and more. Ned’s most recent book is The Border Between Seeing and Thinking (OUP, 2023).

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. This is Barry’s third appearance on the show. He was last on episode 189 with David Albert, in which Robinson, David, and Barry discussed David and Barry’s joint program known as “The Mentaculus”, which they use to solve many problems in the foundations of physics, from probability to the direction of time. In this episode, Barry and Robinson discuss the philosophical foundations of science, touching on the relationship between science and pseudoscience, Karl Popper, string theory, scientific realism, and many other important debates and figures.

Tim Maudlin is Professor of Philosophy at NYU and Founder and Director of the John Bell Institute for the Foundations of Physics. This is Tim’s seventh appearance on the show. He last appeared on episode 210 with David Albert for a discussion of the measurement problem in quantum mechanics. In this episode, Tim and Robinson talk about Albert Einstein’s theory of special relativity, explaining it from the ground up and elucidating some common misconceptions. More particularly, they get into Einstein’s magnificent mind, how special relativity displaced the theory of the ether, absolute and relative space, the speed and nature of light, the possibility of time travel, relativistic quantum mechanics, and more.

David Albert is the Frederick E. Woodbridge Professor of Philosophy at Columbia University, director of the Philosophical Foundations of Physics program at Columbia, and a faculty member of the John Bell Institute for the Foundations of Physics. This is David’s ninth appearance on Robinson’s Podcast. He last appeared on episode 221 to discuss the measurement problem of quantum mechanics. In this episode, David gives a pedagogical and introductory overview of the problem of time’s arrow, which is one of the most enduring of all physical and philosophical puzzles. David’s most recent book is A Guess at the Riddle (2023).
