 For another Meinongian approach to fictional objects, see Castañeda 1979. Charles Crittenden offers a view in a Meinongian spirit but with a later-Wittgensteinian twist (Crittenden 1991). Like Parsons, Crittenden maintains that some objects do not exist and that fictional objects are such objects. Following later Wittgenstein, however, he sees no need to go beyond describing the “language game” we play in our fictional discourse and dismisses all metaphysical theorizing. Robert Howell criticizes Parsons’ theory, among others, and recommends an approach which construes fictional objects as non-actual objects in fictional worlds, where fictional worlds include not just possible but impossible worlds (Howell 1979). Nicholas Wolterstorff argues for the view that fictional objects are kinds (Wolterstorff 1980). For criticism of this view, see Walton 1983. Van Inwagen 2003 contains useful compact discussions of some Meinongian and non-Meinongian theories of fictional objects.
