Politeness, founded upon such a rule, becomes the expression, in graceful manner, of social virtues. The spirit of politeness consists in a certain attention to forms and ceremonies, which are meant both to please others and ourselves, and to make others pleased with us; a still clearer definition may be given by saying that politeness is goodness of heart put into daily practice; there can be no true politeness without kindness, purity, singleness of heart, and sensibility
