Davidson and first-person authority: Parataxis and self-expression

Donald Davidson's explanation of first-person authority turns on an ingenious account of speakers' knowledge of meaning. It nonetheless suffers from a structural defect and yields, at best, expressive know-how for speakers. I argue that an expressivist strand already latent in Davidson's paratactic treatment of the semantics of belief attribution can be exploited to repair the defect, and so to yield a plausible account of first-person authority.
