Abstract
Whether the sensible knave can take pride in herself is a question not merely curious but potentially devastating for Hume's moral theory. Hume assuredly classifies knavery a vice, but given his doctrine that it belongs to virtue to produce pride, then if she can take pride in herself qua knave, the knave is positioned to claim that knavery is, and ought to be recognized as, a virtue. And if this is true, then either Hume is mistaken to have classified knavery as a vice or, if he is not mistaken, his moral theory yields incoherencies— the same quality being both a virtue and a vice.
