Transmission of Warrant-failure and the Notion of Epistemic Analyticity

In this paper I will argue that Boghossian’s explanation of how we can acquire a priori knowledge of logical principles through implicit definitions commits a transmission of warrant-failure. To this end, I will briefly outline Boghossian’s account, followed by an explanation of what a transmission of warrant-failure consists in. I will also show that this charge is independent of the worry of rulecircularity which has been raised concerning the justification of logical principles and of which Boghossian is fully aware. My argument comes in two steps: firstly, I will argue for the insufficiency of Boghossian’s templatewhich ismeant to explain how a subject can acquire a warrant for logical principles. I will show however that this insufficiency of his template can be remedied by adopting what I call the Disquotational Step. Secondly, I will argue that incorporating this further step makes his template subject to a transmission of warrant-failure, assuming that certain rather basic and individuallymotivatedprinciples hold.Thus,Boghossian’s account faces a dilemma: either he adopts theDisquotational Step and subjects his account to the charge of a transmission of warrant-failure, or he drops this additional step leaving the account confronted with explaining the gap that has previously been highlighted. I will then suggest various rejoinders that Boghossian might adopt but none of which—I will argue—can resolve the dilemma. Lastly, I will raise and briefly discuss the question whether this worry generalizes to other accounts, such as Hale and Wright’s that aim to explain our knowledge of logic and/or mathematics in virtue of implicit definitions.
