 (It is worth noting that Yablo also seems to think that, at least sometimes, pure mathematical sentences have real contents—i.e., really say things—that are nominalistic and true. For instance, he thinks that, at least sometimes, sentences like ‘3 + 2 = 5’ say things like if there are three Fs and two Gs, then (barring overlap) there are five F-or-Gs. Moreover, at times, Yablo seems to at least hint at the view that, at least sometimes, when we utter sentences like ‘3 is prime,’ what we’re really saying is that ‘3 is prime’ is true or acceptable according to the theory (or the story, or the game) of arithmetic. It’s not clear how seriously Yablo takes this idea, however; at any rate, it seems pretty clear that if he endorses it at all, he thinks it’s true in only some contexts, i.e., of only some pure mathematical utterances. Whatever Yablo’s view is, though, it’s important to note that views of this general kind—i.e., views that take pure mathematical sentences to have real contents, or really say things, that are nominalistic and true—are not versions of fictionalism at all, as that view has been defined here. They are rather versions of paraphrase nominalism, and so they are subject to the argument against that view given in section 1.2. We will return (very briefly) to the issue of whether Yablo’s view is really a version of fictionalism in section 2.3.)
