Achille Varzi is the John Dewey Professor of Philosophy at Columbia University and Bruno Kessler Honorary Professor at the University of Trento. He is a world-renowned metaphysicist and logician, and widely regarded as the greatest living mereologist. Yet despite all this Robinson asks Achille about his sleep habits, though afterward they discuss some more important philosophical questions: What is ontology? What is metaphysics, and how is it different from physics? After some tangents on nominalism and truthmakers, the conversation ends with a reflection on some of the late Saul Kripke’s contributions to philosophy.
