– Warrant transmission

Abstract: In Boghossian's 1997 paper, 'Analyticity ' he presented an account of a priori knowledge of basic logical principles as available by inference from knowledge of their role in determining the meaning of the logical constants by implicit definition together with knowledge of the meanings so-determined that we possess through our privileged access to meaning. Some commentators (e.g. BonJour (1998), Glüer (2003), Jenkins (2008)) have objected that if the thesis of implicit definition on which he relies were true, knowledge of the meaning of the constants would presuppose knowledge of the very logical principles knowledge of which the account purports to explain. A consequence would seem to be that implicit definition is incompatible with privileged access. I argue that whilst it is possible for Boghossian to defend against these objections the form of argument he proposes does exhibit a subtle form of question begging such that it exhibits a transmission of warrant-failure
