 The arguments given here are supposed to motivate the idea that ordinary mathematical sentences like ‘4 is even’ are not plausibly interpreted as being about physical or mental objects—or more specifically, that they are better interpreted as being about (or at least purporting to be about) abstract objects. But one might object here that, as an interpretation of ordinary mathematical discourse, the platonist/fictionalist view is no more plausible than physicalism or psychologism. For one might find it implausible to suppose that when ordinary folk make mathematical claims, they intend to be speaking about abstract objects.
