  Campbell argues that an adequate account of the nature of our conscious experience of objects should accommodate the fact that such conscious experience performs a significant explanatory role. According to Campbell, such conscious experience provides us with knowledge of what our perceptual demonstrative terms, like ‘this’ and ‘that’, refer to. Furthermore, according to Campbell, the knowledge of the semantic value of the demonstrative that such conscious experience provides us with, justifies and causes the pattern of use we make of that demonstrative in our reasoning. The relevant patterns of reasoning we engage in reflect our conception of the object referred to as mind-independent. So, Campbell argues, our conscious experience of objects has a role to play in explaining what provides us with our conception of the objects of perception as mind-independent. Campbell argues that it is only the relational view of experience that can adequately acknowledge the way in which conscious experience plays this explanatory role, so competing accounts of experience should be rejected.
