Abstract

This paper develops and defends a compound powerful qualities view of properties. According to this view, properties are essentially composed of distinct powerful and qualitative elements. First, I outline an argument for the compound powerful qualities view, based on the claim that it has the explanatory power of other views, without incurring their costs. Second, I argue that the view has the resources to explain how properties are individuated, by claiming that properties are partially individuated by their qualitative elements, and partially by their powerful elements. Third, I distinguish two versions of the view, one of which says that the qualitative and powerful are parts of properties, the other of which says that they are aspects of properties. I argue that the parthood view is the more parsimonious because it can avoid postulating a novel metaphysical relation. Fourth, I argue that the relation between the powerful and qualitative elements of a property is necessary, and lay out various viable options concerning what the relation might be, including grounding and primitivism.
