 If the fictions disagreed sufficiently, there may even be fictions which meet the constraints but which differ on matters which are linked through the fictionalist’s biconditionals with literal modal claims. (This is only possible if the modal truths themselves are not being appealed to as constraints on acceptable fictions, so is not a problem which faces the timid modal fictionalist). If the constraints are not enough to uniquely determine the truth-value of every modal claim, then not only the determinacy of the content of the fiction but the determinacy of the truth-value of some modal claims is at stake. Are those modal claims true or false, or neither? Might they be fiction-relative, so there are no-fault disagreements about them?
