Potentialities as properties

In Potentiality: From Dispositions to Modality , Barbara Vetter attempts to ground modality in properties that she calls “potentialities”. Whether potentialities are up to this task depends on what properties are. However, major accounts of the metaphysics of properties, such as Class Nominalism, Trope Theory, Immanent Realism, Platonism, are incompatible with Vetter’s claims about potentialities. Nevertheless, a modified account of potentialities might be compatible with Immanent Realism or Trope Nominalism.
