 As set out, this is an argument for hermeneutic fictionalism. Revolutionary fictionalism, aiming to secure a purpose that mathematical discourse can serve even if mathematical entities do not exist, would not avert the threat that the eliminativist antirealist would have to say of ordinary speakers that they are in massive error. But there is a nearby argument for revolutionary fictionalism. It goes like this: Eliminativist antirealism threatens to come at a serious cost. If by the lights of our philosophy of mathematics there are no mathematical entities, it seems mathematical discourse must be abandoned (because mathematical utterances are systematically untrue): such discourse cannot be worthwhile. It is here that revolutionary fictionalism comes to the rescue: so long as there is some worthwhile aim of mathematical discourse despite the nonexistence of mathematical entities, mathematical discourse need not be abandoned.
