 There is a more specific worry that remains even if a suitable account of what constraints there are on the modal fiction can be given. This is that it is too contingent a matter whether there is a modal fiction at all. After all, if there had never been any sentient creatures, no stories would ever have been told, and even if the modal fiction is construed as a Platonic entity (a collection of propositions, perhaps), it may never have been a fiction if it was never expressed by story-tellers. (Of course if nothing hangs on whether or not it is a fiction, then this will not worry the Platonist modal fictionalist). This worry, again, is particularly pressing if modal truth is to depend on the contents of the fiction, since it does not seem that whether or not blue swans are possible, for example, depends on whether or not anyone ever told stories. There are responses to this worry, and responses to these responses: see Nolan 1997a, Kim 2005 or Dombrovszki 2017.
