 As became clear in section 2.2, while fictionalists think that sentences like ‘2 + 2 = 4’ are strictly speaking false, they nonetheless think they’re “correct” in some sense of the term. What, then, is the fictionalist’s attitude toward these sentences? Following Bas van Fraassen (1980), who endorses a similar view with respect to empirical science, the standard fictionalist line here is that they accept sentences like ‘2 + 2 = 4’ without believing them. How exactly acceptance should be defined is a matter of some controversy, but one obvious way to proceed here is to claim that fictionalists accept a pure mathematical sentence S if and only if they believe that S is true in the story of mathematics.
