Full Idea
Lovers of beauty find pleasure in things that are pleasant by nature, and virtuous actions are of this kind, so that they are pleasant not only to a particular type of person but also in themselves.
Gist of Idea
Many pleasures are relative to a person, but some love what is pleasant by nature, and virtue is like that

A Reaction
An optimistic but crucial claim that virtue is dictated by nature, and so can't just be relative to individuals. The claim that some things are 'pleasant by nature', rather than just being liked by some individuals, is controversial but appealing.
