Show me a community or a country where all the minor vices are discouraged and I will show you one bereft of major virtues.

If virtue cannot shine bright, but by the conflict of contrary appetites, shall we then say that she cannot subsist without the assistance of vice, and that it is from her that she derives her reputation and honor?
