 Another mixed strategy is rarely explicitly endorsed, though it may be implicit in many theorists’ talk. By far the majority of realists about possible worlds take them to be abstract objects of some sort: sets of sentences or propositions, uninstantiated world-properties, unactualised maximal facts, or perhaps even as sui generis simples. However, their approach to merely possible objects is often less explicitly spelled out. As well as possible worlds, merely possible objects such as blue swans, my counterparts, Newtonian masses, XYZ, and many others are discussed and quantified over. Some abstractionists will wish to identify such merely possible objects with actual abstract objects — perhaps uninstantiated properties that are less than world-properties, descriptions of parts of worlds, set-theoretic representatives, or whatever. But many more will not. This is for at least three reasons. The first is the intuition, never entirely quelled, that a merely possible blue swan should be blue and a swan. Abstract objects are rarely, if ever, either. The second is that it is often thought that the whole point about merely possible objects is that they do not exist, but might have. Admitting their literal existence by identifying them with actual existing abstract objects will go against the grain for many. Finally, many theories of possible worlds lack obvious candidates to play the roles of merely possible objects. This is most obvious for those theories that take possible worlds to be simples, but it is also not straightforward to divide a set of propositions into “object shaped” components, or to distinguish one merely possible object from its duplicates if one identifies worlds with world-properties, and furthermore seeks to divide these up to yield merely possible less-than-world-sized objects. Fictionalism about merely possible objects is an underappreciated theory, and should perhaps recommend itself to more abstractionists about possible worlds than it in fact does.
