Intellectual virtues are qualities that make us excellent thinkers. There are different analyses of exactly which qualities count as intellectual virtues: virtue responsibilists have emphasized praiseworthy character traits, such as open-mindedness and intellectual humility, while virtue reliabilists have emphasized reliable skills and faculties, such as vision, memory, and skills of logic. Importantly, all agree that intellectual virtues are (i) excellences, as opposed to defects; and (ii) distinctively intellectual and not, or not simply, moral. In other words, intellectual virtues are qualities that make us excellent (and not defective) as thinkers, not (or not simply) as people in general. This bibliography provides an overview of philosophical work on the intellectual virtues. It includes articles and books addressing responsibilist and reliabilist analyses of the structure of intellectual virtue; analyses of individual intellectual virtues; the application of intellectual virtue to education and other professional fields; the role of intellectual virtues in epistemology; and, finally, the structure of intellectual vice. It also includes some historical sources on intellectual virtue, though its focus is contemporary. Analyses of intellectual virtue (and of individual intellectual virtues) have developed in tandem with the epistemological subfield of virtue epistemology, which employs the notion of intellectual virtue in an account of knowledge. These analyses also frequently draw on virtue ethics, especially in the Aristotelian tradition. Some of the sources cited touch upon connections between intellectual virtue and these fields, though a fuller treatment of these topics can be found in the corresponding bibliographies on Virtue Epistemology and Virtue Ethics.
