An Enquiry Concerning the Principles of Morals

[Footnote: It is the nature and, indeed, the definition of virtue, that it is A QUALITY OF THE MIND AGREEABLE TO OR APPROVED OF BY EVERY ONE WHO CONSIDERS OR CONTEMPLATES IT. But some qualities produce pleasure, because they are useful to society, or useful or agreeable to the person himself; others produce it more immediately, which is the case with the class of virtues here considered.]

AS the mutual shocks, in SOCIETY, and the oppositions of interest and self-love have constrained mankind to establish the laws of JUSTICE, in order to preserve the advantages of mutual assistance and protection: in like manner, the eternal contrarieties, in COMPANY, of men's pride and self-conceit, have introduced the rules of Good Manners or Politeness, in order to facilitate the intercourse of minds, and an undisturbed commerce and conversation. Among well-bred people, a mutual deference is affected; contempt of others disguised; authority concealed; attention given to each in his turn; and an easy stream of conversation maintained, without vehemence, without interruption, without eagerness for victory, and without any airs of superiority.
