In proposing this, he self-consciously departs from our ordinary, intuitive concept of fiction, which he sees as only “a rough everyday classification” (Walton 1990: 72) in urgent need of refinement (among other problems, the ordinary concept of fiction is liable to treat certain works, for example, didactic dialogues like Berkeley’s Three Dialogues between Hylas and Philonous (1713), as both non-fiction and fiction; Walton 1990: 72).
