Good-breeding is the art of showing men, by external signs, the internal regard we have for them. It arises from good sense, improved by conversing with good company.
Cato the YoungerIt is remarkable that men, when they differ in what they think considerable, will be apt to differ in almost everything else; their difference begets contradiction; contradiction begets heat; heat quickly rises into resentment, rage, and ill-will; thus they differ in affections, as they differ in judgment.
Cato the Younger
