Our virtues and vices are not the only causes of love and hatred. Wealth and property, family and social relations, bodily qualities and attributes may also generate love or hate (T 2.1.2.5; 2.1.7.1–5/279, 294f; DP 2.14–33). It is, nevertheless, our virtues and vices, understood as pleasurable or painful qualities of mind, that are “the most obvious causes of these passions” (T 2.1.7.2/295; cp. 3.1.2.5/473; and also 3.3.1.3/574–5). In this way, by means of the general mechanism of the indirect passions, virtue and vice give rise to that “faint and imperceptible” form of love and hatred which constitutes the moral sentiments. This is essential to all our ascriptions of moral responsibility.
