Abstract: I has the logical character, inferential role, referential function, expressive use, and communicative role of a deictic term. Uses of I share the referential security and identificatory ease of certain uses of other deictic terms. I has a distinct character within the group due to kind salience, expressive demonstration, communicative demonstration, and certain other features. These findings show that the whole standard account of indexicals and demonstratives, due to Kaplan, rests on two false principles and must be replaced. More positively, these findings offer new ways to explore first-personal thinking and self-knowledge, together with broader questions dependent on them such as practical reasoning, belief-acquisition, and belief-ascription.

Keywords: deictic term, indexical, salience, singular personal pronouns, first-personal thinking, self-knowledge, practical reasoning, belief-acquisition, belief-ascription, epistemology,
