Descartes s concern with the proper method of belief formation is evident in the titles of his works e.g., "The Search after Truth," "The Rules for the Direction of the Mind" and "The Discourse on Method of rightly conducting one s reason and seeking the truth in the sciences." It is most apparent, however, in his famous discussions, both in the "Meditations" and in the "Principles," of one particularly noteworthy source of our doxastic errors namely, the misuse of one s will. What is not widely recognized, let alone appreciated and understood, is the relationship between his concern with belief formation and his concern with virtue. In fact, few seem to realize that Descartes regards doxastic errors as "moral" errors and as "sins" both because such errors are intrinsically vicious and because they entail notably deleterious social consequences.

"Reforming the Art of Living" seeks to rectify this rather common oversight in two ways. First, it aims to elucidate the nature of Descartes s account of virtuous belief formation. Second, it aims both (i) to illuminate the social significance of Descartes s philosophical program as it relates to the understanding and practice not of science, but of religion and (ii) to develop a kind of Leibnizian critique of this aspect of his program. More specifically, it aims to show that Descartes s project is dangerous, insofar as it is subversive not only of traditional Christianity but also of other traditional forms of religion, both in theory and in practice."

Recent work at the intersection of moral philosophy and the philosophy of psychology has dealt mostly with Aristotelian virtue ethics. The dearth of scholarship that engages with Hume's moral philosophy, however, is both noticeable and peculiar. Hume's Moral Philosophy and Contemporary Psychology demonstrates how Hume's moral philosophy comports with recent work from the empirical sciences and moral psychology. It shows how contemporary work in virtue ethics has much stronger similarities to the metaphysically thin conception of human nature that Hume developed, rather than the metaphysically thick conception of human nature that Aristotle espoused. It also reveals how contemporary work in moral motivation and moral epistemology has strong affinities with themes in Hume's sympathetic sentimentalism.

How do people form beliefs, and how should they do so? This book presents seventeen new essays on these questions, drawing together perspectives from philosophy and psychology. The first section explores the ethics of belief from an individualistic framework. It begins by examining the question of doxastic voluntarism-i.e., the extent to which people have control over their beliefs. It then shifts to focusing on the kinds of character that epistemic agents should cultivate, what their epistemic ends ought to be, and the way in which these issues are related to other traditional questions in epistemology. The section concludes by examining questions of epistemic value, of whether knowledge is in some sense primary, and of whether the ethics of belief falls within the domain of epistemology or ethics. The second section extends this traditional debate to issues concerning the social dimensions of belief formation. It begins with essays by social psychologists discussing the past three decades of research in 'lay epistemics'. It continues by examining Humean, Kantian, and feminist insights into the social aspects of belief formation, as well as questions concerning the ethics of assertion. The section concludes with a series of essays examining a topic that is currently of great interest to epistemologists: namely, the significance of peer disagreement.
