 A structurally similar approach is suggested by Christopher Hughes. Think of first-level properties as David Lewis (1986, 50 ff.) does: as sets of actual and possible individuals. Then the property of being red will be the set of all actual and possible red individuals and the property of being perfectly powerful will be the set consisting of all actual and possible perfectly powerful individuals. But there is only one such individual, God. Only God is perfectly powerful and only God can be perfectly powerful. So perfect power = {God}. As Hughes (1989, 65) notes, Quine holds that a singleton and its member are identical. If so, then perfect power = {God} = God. It should be added that if we have already abandoned nonconstituent ontology with its rigid bifurcation of the concrete and the abstract according to which the two realms are disjoint, then we no longer have a reason to argue that a concrete individual and its singleton must be distinct on the ground that the former is concrete while the latter is abstract. Constituent ontology allows for a sort of ‘coalescence’ of the concrete and the abstract, the particular and the universal. Indeed, such a coalescence is what we find in the simple God who is in some sense both concrete and abstract in that he is a nature that is its own suppositum.
