Abstract
An intellectual virtue is a quality bound to help maximize one’s surplus of truth over error; or so let us assume for now, though a more just conception may include as desiderata also generality, coherence, and explanatory power, unless the value of these is itself explained as derivative from the character of their contribution precisely to one’s surplus of truth over error. This last is an issue I mention in order to lay it aside. Here we assume only a teleological conception of intellectual virtue, the relevant end being a proper relation to the truth, exact requirements of such propriety not here fully specified.
