Dispositional accounts of free will provide a promising avenue for compatibilists about free will and determinism to respond to manipulation arguments, but requires an adequate account of masked and finkish abilities. In this thesis, I argue that an account of masked dispositions that addresses the context sensitivity, gradability, and dispositional quality of masks can allow dispositional compatibilists to level viable responses to various manipulation arguments. I address my response towards both Pereboom’s and Mele’s manipulation arguments.
