Humes definitions of virtue

Hume offers not one, but two definitions of virtue: a more famous one in terms of usefulness or agreeability to the self or to others, and a second in terms of eliciting approbation or disapprobation from spectators. Some scholars endorse the former definition as the more fundamental one; others endorse the latter as more fundamental. This paper argues that neither definition is more fundamental than the other. The two definitions are distinct but complementary, in that they have to rely on each other in various ways.
