Yet another Theory of the Metaphysical Difference between Genuine Perceptions and Hallucinations

Abstract

In this article, first of all, the author wants to show that a new justification can be provided for the idea, originally maintained in the disjunctivist camp, that genuine perceptions and hallucinations are metaphysically different kinds of mental states, independently of the fact that they all are perceptual experiences. For even if they share their phenomenal character and their representational content is put aside for the purpose of their metaphysical individuation, as some conjunctivists maintain, they still differ in their mode, insofar as they differ in their functional role. Once things are so put at the metaphysical level, moreover, this account of perceptual experiences leaves room for reintroducing content for such experiences from the rear door; namely, as a (metaphysically irrelevant) singular representational content, just as some direct realists have originally suggested. Finally, this move enables the account to explain not only some intuitive data about perceptual experiences, but also to corroborate its viability, even if it does not rely on antiskeptical motivations.
