This paper argues that the best way to think about intellectual norms, or an ethics of belief, is by reflecting on the virtues and vices of inquiry. A theory of intellectual virtue provides a promising framework for evaluating different practices of inquiry in relation to the generic aim of truth. However, intellectual virtues are too often conflated with measures of reliability in mainstream epistemology, resulting in an overly narrow conception of epistemic value. Prominent reliabilists such as Alvin Goldman state that (...) a practice of inquiry is virtuous just in case it maximizes true belief. I argue that this reliabilist interpretation of virtue lacks the resources to explain evaluative distinctions between ways of maximizing true belief, such as the difference between maximizing accuracy and maximizing precision. With the aid of examples, I show that praiseworthy attributions of reliability are parasitic on attributions of topic-specific aims and skills that constitute their own characteristic standards of success, suggesting that bare truth-maximization is not the fundamental criterion of epistemic value. To accommodate the full range of intellectual norms that shape our practices, I conclude that we need a concept of virtue thicker than mere reliability. (shrink)

My dissertation presents the outlines of a theory about knowledge and virtue. The core idea is that the nature of knowledge is best understood by reflecting on its role in intellectual practice. What distinguishes knowledge from true opinion is not primarily its causal history or its internal structure, as standard theories argue, but rather the way in which knowledge is embedded or rooted in our styles of explanation, modes of communication and methods of teaching. Knowledge becomes rooted in our practices (...) through the cultivation and exercise of intellectual virtue, or the dispositions and skills needed to master varieties of theoretical and practical reasoning. The link to virtuous intellectual activity is what makes knowledge more valuable than true opinion. This suggests that the virtues of intellectual practice are central to our understanding of the nature of knowledge. I devote the first half of the dissertation to showing why we need a theory of virtue in epistemology and how in general that theory ought to be formulated. In the second half, I address skeptical objections and other problems that arise during my formulation of the theory. ;The starting point is a puzzle from Plato's Meno about the value of knowledge. As Socrates observed, true belief has the same practical value as knowledge. So why should we prefer the one to the other or even distinguish between the two? Most philosophers agree that true belief is not enough for knowledge, but there is little agreement about what it lacks and why the distinction matters. Standard attempts to fill this gap either conceive knowledge as true belief with the right kind of causal history or as responsibly formed belief with the right kind of rational structure. But neither strategy is satisfactory because neither adequately reflects the role that knowledge plays in intellectual practice. This suggests that there is something wrong with the standard belief-theoretic analysis of knowledge. I develop a new account of the nature and value of knowledge that better explains the connection between the norms of virtuous inquiry and the goal of understanding. (shrink)
