 Another “incompleteness” worry in the literature is that expressed in Nolan 1997a. This is also a worry that the modal fiction will not represent as much as is desirable, though the concern is not confined to those areas in which realists might confess ignorance. (The concern resembles an objection Lewis brings against “sparse linguistic ersatzism” in Lewis 1986, pp. 142–165.) A modal fiction, to be adequate, must represent a very great deal about possible worlds, since there are infinitely many claims about possible worlds that must be part of the content of the fiction, if there are to be enough possible-worlds claims to correspond to all the modal claims we would accept. Only a tiny proportion of the propositions about possible worlds needed will be able to be stated explicitly by the modal fictionalist: constraints of time and space and publication costs will mean that the fictionalist will need to describe the fictional worlds in only a few volumes, while an exhaustive explicit description of even a single possible world as complex as our actual world is beyond our finite resources.
