 Identity claims, however, do not seem to fit this simple model of assertion. As Kripke (1980) argued, identities are either necessarily true or necessarily false. So accepting an identity will either leave the context set unchanged or it will eliminate it altogether. Either way, asserting an identity would be pointless. But clearly it is not. Asserting an identity such as ‘Lloyd is I.L. Humberstone’ can be genuinely informative, ruling out empirical possibilities previously taken to be live options. According to the metasemantic account, (i) the goal of assertion can explain why the assertion of a necessary sentence will lead to a reinterpretation of the content of the asserted sentence, and (ii) the 2D framework helps to specify just which proposition will be conveyed by the sentence within a given conversation.
