This chapter is up to an ambitious task: it develops the first integrated account of the epistemic normativity of constatives. In order to do that, it argues for a generalized knowledge-based account of the epistemic normativity of constative speech, and it develops the corresponding accounts for, respectively, assertives, predictives, retrodictives, descriptives, ascriptives, informatives, confirmatives, concessives, retractives, assentives, dissentives, disputatives, responsives, suggestives, and suppositives. The chapter argues for a knowledge account from three different angles: (1) the nature of communicative speech acts, (2) the relation between assertion and other constatives, and (3) the normativity of belief together with constatives’ epistemic function.
