  Some have argued that a genuine perception of the world is a perceptual state with an intentional content containing demonstrative elements that refer to the items perceived. (See Brewer 2000, Burge 1993, and Tye 2007, Scellenberg 2010, 2013, and 2016. For objections to this idea see Davies 1992 and McGinn 1982.) Acceptance of this view, together with two further assumptions, can lead to the conclusion that the kind of experience that occurs when one perceives the world isn’t one that can occur when one hallucinates, which in turn can motivate a disjunctive approach to perceptual experience in general. The two further assumptions are the following. (a) Truth-evaluable intentional contents with demonstrative elements that successfully refer are object-dependent, and (b) experiences are of the same mental kind only if they have the same truth-evaluable contents. (The latter claim is endorsed by Evans 1981, 1982 and McDowell 1984. For criticisms of this claim see Burge 1983, 1993, 2005, 2010, and Martin 2003).
