Inferential Role/Coextension/Inference/Block: Thesis: the inferential role of coextensive expressions can differ. Thus, the theory of the conceptual role can distinguish between e.g. morning star/evening star, or between "Cicero" and "Tullius". (Intension/Extension). I.e. it is fine-grained enough.
Block knows, however, that this is not guaranteed.
