Abstract for Vetter’s talk

Dispositionalism about modality is the view that metaphysical modality is ultimately based in the dispositional properties of individual objects. The view has gained sympathies over the past few years, but there are as yet few suggestions on how to spell it out. A crucial challenge to any way of spelling it out is what I call a requirement of formal adequacy: the requirement that modal logic must be vindicated by the dispositionalist account. I will develop and defend a version of dispositionalism that meets this requirement. The key to my dispositionalist is a generalization of disposition which, I will argue, is independently motivated if we take dispositions seriously in metaphysics.
