 Walton’s pretense-based version of antirealism has been very influential (for a development of the view, see Everett 2013), but it has also attracted a great deal of criticism. Some have doubted that a sentence’s fictional truth on its conniving use can ground a sense in which it is really true on its non-conniving use (cf. Voltolini 2006), a move that is crucial to his antirealism. Others have doubted that Walton’s appeal to unofficial games of make-believe can yield appropriate antirealist paraphrases for metafictional sentences in general, perhaps because these critics deny that such sentences involve either explicit or implicit appeals to pretense (Thomasson 1999, van Inwagen 2003).
