 Sauchelli 2013 is a recent contribution to this debate that points out another aspect of the problem about artificiality, especially for a fictionalist who intends an analysis of modal claims in terms of a fiction of possible worlds. Many people at different times and in different places have made modal claims: Sauchelli mentions the example of Caesar considering whether he could cross the Rubicon. Most people have little or no contact with fictions of possible worlds, or theories of possible worlds intended to be factual but useable as fictions. Those people lack access to the fictions that are supposed to underpin the truth of their modal claims. Sauchelli claims this makes for both an implausible modal epistemology for figures like Caesar and an implausible account of how people like Caesar can even understand modal claims.
