Abstract

I examine here whether reliability is a defining feature of (moral or intellectual) virtues. I argue (1) that reliability is not a defining feature of a virtue where virtues are conceived (as they often are) as “personal excellences,” but (2) that there is another (also intuitive and familiar) conception of a virtue according to which reliability is a defining feature. I also argue (3) that even on the former conception, a certain rational belief pertaining to reliability is essential and (4) that reliability itself, while not a defining feature of a virtue thus conceived, nevertheless is a concomitant of it.
