 Fourth, it is sometimes assumed that if experiences are structured by attitude and content, then experience types will be individuated by their specific attitude plus their contents, so that if an experience E1 with content C is type-identical to an experience E2, then E2 will also have content C, and E1 and E2 will instantiate the same experiential attitude. The source of this idea may be an analogous claim about beliefs: namely, the claim that if belief B1 with content C is the same belief-type as B2, then B2 will also have content C. However, it should not be taken as a consequence of the claim that experiences have content that their contents individuate experience-types. Rather, this is a substantive claim that needs both refinement and defense. Even if beliefs were individuated by their contents, that would not suffice to show that experiences are as well. Some additional reason would be needed to think that experiences and beliefs are alike in this respect.
