This monograph works at the intersection of two of the most popular and growing fields in epistemology: epistemic normativity or value and virtue epistemology. By challenging two hitherto un- or under-explored sets of assumptions?epistemological orthodoxies?operative in those fields and, by rejecting them, the book develop novel approaches in those fields.

The book argues that what is needed is an internalist (i.e. non-externalist) mode of epistemic virtue. To accomplish this, it draws on Stoic moral theory, whereby the deployment of virtue?no matter whether one has any ?external? success?suffices for completely successful action.
