John Burgess is John N. Woodhull Professor of Philosophy at Princeton University, where he works in mathematical and philosophical logic and the philosophy of mathematics. In this episode, Robinson and John discuss realism in the philosophy of mathematics, and while the nature of this question is itself disputed, it can be roughly described as concerning the extent to which we should be committed to the mind-independent truth of mathematical theorems, or to the existence of the objects they apparently describe. Robinson and John begin by addressing the nuances of this question, and they then turn to various developments in mathematics that have been historically associated with realism—set theory, in particular—as well as specific philosophical positions associated with realism (such as Platonism) and anti-realism (such as conventionalism). John’s most recent book is Set Theory (Cambridge, 2022).
