Seven virtues
The "Catechism of the Catholic Church" defines virtue as "a habitual and firm disposition to do the good." Traditionally, the seven Christian virtues or heavenly virtues combine the four classical cardinal virtues of prudence, justice, temperance and courage (or fortitude) with the three theological virtues of faith, hope and charity. These were adopted by the Church Fathers as the seven virtues.
A Treatise of Human Nature
He finishes this general treatment of the natural virtues with a fourfold classification: every natural virtue is either (1) useful to others, (2) useful to the person himself, (3) immediately agreeable to others, or (4) immediately agreeable to the person himself. Of these "four sources of moral distinctions", the most important are the virtues of usefulness, which please us even when mere private interest is at stake: thus we approve of prudence and frugality, and while the vice of "indolence" is sometimes indulged (as an excuse for the unsuccessful or a veiled boast of sophistication), "dexterity in business" wins approval by sheer sympathy with the person's private interest. The two categories of useful virtues are often blended together by sympathy: what hurts me ends up paining others as they sympathize with me, and what hurts others ends up paining me as I sympathize with them. Less important are the virtues of immediate agreeableness: instead of reflecting on the positive tendencies of a mental quality, we simply find it pleasant in and of itself (e.g. wit, insouciance). And even here sympathy plays a major role: we approve of these virtues in large part because they bring pleasure to others or the person himself. Hume concludes with "a general review of the present hypothesis"—viz., that we evaluate character by sympathetically considering its impact on the person himself and others within his sphere of influence—and a brief remark on how "good or ill desert" is explained in terms of the benevolence or anger that come with evaluating (i.e. loving or hating) another person.
