 Should modal fictionalists claim that the story of possible worlds is necessarily false, then Hale argues that they cannot gloss their “according to the fiction of possible worlds ….” prefix as “were the fiction of possible worlds true, then … would be true”. This is because, according to Hale, conditional claims with antecedents which are necessarily false are automatically true, so if the fiction of possible worlds is taken to be necessarily false, then all conditionals of the form “were the fiction of possible worlds true then …” are true, and not merely the ones that the modal fictionalist wishes to endorse. If the modal fiction is to be useful, not everything should be true according to it: examples of claims that had better not be true according to it include the claim that 2+2=7, or the claim that there are no possible worlds.
