Abstract: The inferential role of I is irreducibly deictic. The inferential roles of singular terms are distinguished by appeal to the different mechanisms required to guarantee co-reference in a knowledge-advancing way. Co-typicality is insufficient for variant terms. Anaphoric structures are insufficient for I and other terms used deictically; they depend on identity-judgements and keeping track. The inferential role of I and other deictic terms is irreducibly deictic: it is by singling out individuals made salient in the extra-sentential environment that their uses contribute systematically to what entails what.

Keywords: deictic term, inferential role, anaphora, salience, co-reference, co-typicality, identity-judgements, keeping track, Brandom, singular personal pronouns,
