A presentation for the Australasian Association for Logic Conference at the University of Sydney. I will discuss Tim Williamson’s arguments for the non-contingency of existence (see his Modal Logic as Metaphysics, 2013) and explain how and why they might be reasonably resisted. Along the way, I’ll try to explain the impact of proof theory for theories of meaning and for metaphysics.
