Vance, Chad (Ph.D., Philosophy) In Defense of the New Actualism: Dispositional Modal Truthmakers and the Branching Conception of Possibility Thesis directed by Professor Graeme Forbes Abstract: You could be going for a walk right now. This seems true—but what makes it true? Here is a popular answer : It is true that you could be going for a walk right now because there exists some possible world (beyond the actual world) where you are going for a walk now; or else, because there is some abstract, representational entity which represents you as going for a walk now. I think this is mistaken. I take a more common-sense approach, arguing instead that the modal truths (i.e., truths about metaphysical possibility and necessity) are made true by the capabilities, or dispositional properties, of actual objects.
