But even if these difficulties can all be addressed, it is unclear that the mathematical fictionalist has offered an account of the application of mathematics that allows us to make sense of how mathematical theories are actually applied. After all, the fictionalist account requires us to rewrite the relevant theories, by finding suitable nominalistic versions for them. This leaves the issue of making sense of the actual process of the application of mathematics entirely untouched, given that no such reformulations are ever employed in actual scientific practice. Rather than engaging with actual features of the application process, the fictionalist creates a parallel discourse in an effort to provide a nominalist reconstruction of the use of mathematics in science. The reconstruction shows, at best, that mathematical fictionalists need not worry about the application of mathematics vis-à-vis increasing their ontology. But the problem still remains of whether they are in a position to make sense of the actual use of mathematics in science. This problem, which is crucial for a proper understanding of mathematical practice, still remains.
