 The fundamental work in question concerns the metaphysics of modality, for the most part. But assertoric content does not have much to do with the metaphysics of modality, so the claim that apparently rigid designators as well as nonrigid designators have a descriptive assertoric content seems not to threaten the extent or significance of rigidity: “the propositional content of a sentence in a context is not its modal content” (Stanley 2002,  338).[11]
