In this paper, I flesh out an account of the inferential basing relation using a theory about how humans reason: the mental models theory. I critically assess some of the notions that are used by that theory to account for inferential phenomena. To the extent that the mental models theory is well confirmed, that account of basing would be motivated on empirical grounds. This work illustrates how epistemologists could offer explications of the basing relation which are more detailed and less (...) empirically risky. (shrink)

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. (shrink)
