“Modal Dependence” by Adam Murray, Department of Philosophy, University of Toronto
DATE: Tuesday, February 16
It is typically supposed that metaphysical possibility and necessity are the broadest, or most unrestricted, forms of (genuine) possibility and necessity there are. But not all metaphysical necessities are created equal: we should distinguish between merely actual metaphysical necessity, on the one hand, and absolute metaphysical necessity, on the other. In this talk, I explain why this distinction is important, and show how it may be modeled using the resources of two-dimensional modal semantics.
