  Martin argues for a naïve realist account of the kind of experience one has when one genuinely perceives the world. According to this naïve realist account, when one genuinely perceives the world one is directly aware of mind-independent objects and their features. Furthermore, according to this view, when one perceives the world, the actual objects of perception, the external things such as trees, and tables, which one can perceive, and the properties they manifest to one when perceived, partly constitute one’s conscious experience, and hence determine its phenomenal character. (See Martin’s discussion of naïve realism in his 1997, 1998, 2002, 2004, and 2006.) Since one is not aware of mind-independent objects and their features when one hallucinates, the naïve realist cannot offer the same account of the phenomenal character of hallucinations. The naïve realist is committed, then, to the claim that the kind of phenomenally conscious episode that occurs when one perceives the world is not one that could be occurring were one hallucinating. So in order to preserve his naïve realist account of the phenomenal character of genuine perceptions, Martin advocates a disjunctive account of perceptual experience. According to Martin, genuine perceptions and introspectively indiscriminible hallucinations are not mental events of the same fundamental kind.
