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.

休谟对美德的定义


休谟对美德的定义不是一个，而是两个：一个是更著名的定义，是关于对自我或他人的有用性或可享性，另一个是引起旁观者的认可或不认可。一些学者赞同前一个定义是更基本的定义;其他人则认为后者更基本。本文认为，没有一个定义比另一个定义更基本。这两个定义是不同的，但又是互补的，因为它们必须以不同的方式相互依赖。
