Abstract
The aim of this paper is to connect the traditional epistemological issue of justification with what one might call the “new reasons paradigm” coming from the philosophy of action and metaethics. More specifically, I will show that Conee and Feldman’s mentalism, a version of internalism about justification, can profitably be spelled out in terms of subjective normative reasons. On the way to achieving this aim, I will argue that it is important to ask not just the oft-discussed ontological question about epistemic reasons—what kind of entities are they?—but also: Reasons in which sense are fundamental to justification?
