 Modal fictionalists often focus on the claim that possible worlds are merely fictional entities, and apparent commitment to possible worlds is to be explained in the same sort of way that apparent commitment to ideal gases or frictionless surfaces is to be explained. Rosen 1990 and others have formulated modal fictionalism as a theory that takes talk of possible worlds to be on a par with talk about paradigmatically fictional objects, e.g., Sherlock Holmes (“There is a (non-actual) possible world at which there are blue swans” is to be understood on the model of “There is a brilliant detective at 221b Baker Street”, in Rosen’s example). This goes with an at least partial account of how we are to treat paradigmatically fictional claims: that they are, literally and strictly speaking, false. The literal truth, according to modal fictionalists, is that there are no merely possible worlds (or merely possible situations, or outcomes), and there are no merely possible objects. Strictly and literally speaking, there is no sculpture that I spent this morning making, though there could have been. When the flipped coin comes down heads, there is strictly speaking no outcome of that very throw in which it comes down tails.
