  So far we have focused on Perry's case against Fregean accounts of indexicals in thought and language. Let's move briefly to Perry's positive, anti-Fregean view of indexicality. Perry's views have gone through important and often drastic changes from his early views in (1977) and (1979) to his later views in his (2001), which we shall not try to sort out here, focusing primarily on the earlier view. A view broadly similar to Perry's early view is developed in Kaplan 1977/1989, where Kaplan distinguishes content and character, claiming that the latter captures the cognitive significance of an expression and the former is the bearer of truth value and the object of the propositional attitudes, often being a singular proposition. Perry initially (1977) distinguished “thoughts” and “senses,” but later (1979) and (1980a/b) made the same distinction in terms of belief contents and belief states. (Perry also initially identified the “thought” associated with an expression with its role, which is proven false by cases like the Enterprise case discussed above. If an expression's role is identified with its linguistic meaning, then the two occurrences of ‘this’ surely have the same role. The two utterances of ‘this’ have distinct associated demonstrations, but demonstrations are not part of linguistic meaning.) The core idea is that an adequate account of indexicality in thought and language involves two distinct items, one that is roughly characterized by Truth and Attitude — propositions — and the other that is roughly characterized by Accept and is intended to capture the “cognitive significance” of an expression and through which propositions are grasped. The former is, in the case of indexical beliefs, a singular proposition. This distinction, Perry claimed, is the key to solving the problems with self-locating beliefs that we have discussed above; it is the Fregean's identification of the items that answer to Accept, Truth, and Attitude that leads to the problems surveyed above.
