  As Campbell himself points out, his argument presses very hard the idea that experience of objects has this explanatory role to play. Some issues of contention here are the following: (a) Whether an account of the nature of conscious experience really does have a role to play when it comes to an explanation of the fact that we have a conception of objects in the world as mind-independent. (b) If the nature of conscious experience does have such an explanatory role to play, whether it is the one that Campbell identifies—i.e., that of causing and justifying the use we make of demonstrative terms that refer to the mind-independent objects we perceive. (c) Whether the relational view of experience really does have the resources to play the explanatory role that Campbell assigns to it. (For criticism of Campbell’s argument, see Burge 2005, Rey 2005, and Cassam 2011).
