Existential states of affairs

But we can avoid this consequence by drawing on the point that the realizer will consist in part of a concrete state of affairs, in part of an existential state of affairs. The concrete state of affairs will be specific to the particular property whose instance is realized and can be viewed as the core of the realization of the instance. The positive part of the existential state of affairs will consist in its being the case that there are, appropriately related to that concrete state of affairs, other microphysical states of affairs that are realizers of instances of a number of other properties, each of these properties being of one of the kinds that a thing of the relevant sort must exemplify. This positive existential state of affairs will obtain in virtue of there existing a number of states of affairs that are partly concrete, each of which will be a total realizer of one of the properties coinstantiated with... 

Although I have spoken of the core as concrete, it probably has to include (as the N-realizer does) negative existential states of affairs. For example, the states of affairs contributing to the instantiation of my height has to include its not being the case that below my feet and above my head there are microentities of certain sorts related to those inside my body in the ways the latter are related to one another. 

First, a property instance would seem to be itself a concrete state of affairs, one having just one constituent object, the subject of the property, and just one constituent property, namely, the property instantiated. The realizer of the property instance is partly a concrete state of affairs having a vast number of microentities as constituent objects and a vast number of properties of these as constituent properties, and it contains in addition positive and negative existential states of affairs. If states of affairs are individuated by what their constituent objects are and how these are propertied...
