Abstract

In Section 1, we make some preliminary remarks about the concept of epis‐ temic entitlement, understood in terms of ex ante rationality. In Section 2, we argue that a certain epistemological view – one according to which ex ante rationality is solely a func- tion of available reasons – is inadequate. In Sections 3-4 we will esh out an alternative view about ex ante rationality, one according to which forming a certain belief is rational for a subject S only when S knows how to reason in a certain way. In Section 5 we explore some consequences of our view and we describe the main challenge that we must meet in future work.
