In this paper Boghossian better specifies his conception and defends it against some objections moved to previous formulations. In particular, he tries to reply to the objection that "there can be no epistemically analytic sentences that are not also metaphysically analytic, and that the notion of implicit definition cannot explain a priori entitlement' (p. 15). He thus introduces the distinction between an inferential and a constitutive way in which "facts about meaning might generate facts about entitlement' (p. 15) and concludes his paper by outlining a theory of the constitutive way that modifies some of his preceding ideas.
