Graham Oppy is Professor of Philosophy at Monash University. Before that, he did his undergraduate work in Melbourne and his graduate work at Princeton. Though Graham is best known as a philosopher of religion, he has also published on the philosophy of math, language, aesthetics, and more. In this episode, Robinson and Graham begin by discussing the nature of argument: What makes an argument successful? What’s a good argument? How should we think about arguments in areas of deep disagreement? They then move on to a discussion of ontological arguments in the philosophy of religion, where one argues for the existence of god—or gods—without any prior assumptions.Ontological Arguments: https://plato.stanford.edu/entries/ontological-arguments/Majesty of Reason: https://www.youtube.com/@MajestyofReasonOUTLINERobinson’s Website: http://robinsonerhardt.comRobinson Erhardt researches symbolic logic and the foundations of mathematics at Stanford University.
