Logic and Metaphysics Workshop

Title: An Indeterminate Universe of Sets

Speaker: Chris Scambler, NYU

Abstract: The questions “Is there one and only one universe of sets?” and “Does every set-theoretic proposition have a determinate truth-value?” are often taken to be intimately related; there is, for example, a widespread tendency to assume that answering the former affirmatively commits one to the same with respect the latter. I’ll argue that this tendency is mistaken. I present a view on which there is a unique but indeterminate universe of sets, couched in a non-classical (semi-intuitionistic) logic, drawing on the work of Solomon Feferman.
