 One might find these sorts of proposals wanting since they only characterize the types of dependence that hold between constituents of unified wholes (whether they are states of affairs or nuclear bundles of tropes). But, the objection goes, they do not account for the difference between constituents considered outside of such unities and constituents in a unified whole. Here, Perovic (2016) is happy to admit that she is not trying to provide such an account in the first place. Following Armstrong, she takes the world to be exhausted by states of affairs and takes particulars and universals to exist only in states of affairs.
