Full Idea
That we have some intuitive belief in the unity of the virtues is shown by our reaction to stories of a person who has shown an exceptional virtue, but also done something morally repellent.
Gist of Idea
We are puzzled by a person who can show an exceptional virtue and also behave very badly

A Reaction
A nice observation, but not enough to establish the unity of virtue. People tend to love all virtue, but it is not obviously impossible to love selected virtues and despise others (e.g. love courage, and despise charity).
