Abstract
Appeal to the idea of an epistemic virtue promises insight into our practices of epistemic evaluation through employing a distinctive view of the ways in which we formulate and respond to reasons. Traits of ‘epistemic character’ guide our reasoning and reflection, and can be responsible for various forms of irrationality. One component of such a view is that emotions, sentiments and other affective states are far more central to questions of epistemic rationality than is commonly supposed. This paper explains why this is so, and then illustrates the value of this way of looking at the matter by considering two particular examples: the role of states of doubt in regulating our deliberations and inquiries; and the character of our response to some distinctive kinds of irrationality. This will involve a brief discussion of some forms of epistemic akrasia.
