 It is questionable the degree of credence he continues to assign to this view, given that Walton (2015), recanting his earlier reductive account of fictionality—according to which “[a] proposition is fictional… just in case there is a prescription to the effect that it is to be imagined”—claims that “prescriptions to imagine are necessary but not sufficient for fictionality” (2015: 17). Walton (2015) states that fictionality turns out to be more fundamental than he had originally thought (Walton 1990—up to 2015).
