We provide an account of necessary a posteriori identity statements that relies upon Perry’s multipropositionalism. On our account an utterance of, e.g., ‘Hesperus is Phosphorus’, semantically makes available several propositions, one of which is necessary (and a priori) and another of which is a posteriori (and contingent). Since our view resembles two-dimensionalism, one might assume that it is undermined by the sorts of nesting arguments that Soames and others have raised against two-dimensionalism. We demonstrate, however, that our account is immune to such nesting arguments.
