Thought Sharing, Communication, and Perspectives about the Self

Many scholars are ready to accept that first person thought involves a special way w such that, for any thinker x, only x can access the first person way w of thinking about x. Standard articulations of this Frege-inspired view involve a rejection of the strict shareability of first person thought. I argue that this rejection eventually forces us to renounce an intuitively plausible characterisation of communication, and specifically, disagreement. This result invites us to explore alternative articulations which, still within an overall Fregean framework, may better explain how first person thoughts reach out into a public, shareable dimension. Here I shape this possibility in terms of perspectives, i.e. ways of thinking that do not individuate concepts or thoughts. Perspectives, I submit, can serve to unproblematically accommodate basic disagreement in indexical cases and to outline the dynamic character of first person thought.
