This paper argues against the unity of the virtues, while trying to salvage some of its attractive aspects. I focus on the
strongest argument for the unity thesis, which begins from the premise that true virtue cannot lead its possessor morally
astray. I suggest that this premise presupposes the possibility of completely insulating an agent’s set of virtues from any
liability to moral error. I then distinguish three conditions that separately foreclose this possibility, concentrating on
the proposition that there is more to morality than virtue alone—that is, not all moral considerations are ones to which some
virtue is characteristically sensitive. If the virtues are not unified, the situationist critique of virtue ethics also turns
out to be more difficult to establish than some have supposed.
