The Art of Worldly Wisdom(118)

Acquire the Reputation for Courtesy. This is enough to make you liked. Politeness is the main ingredient of culture,—a kind of witchery that wins the regard of all as surely as discourtesy gains their disfavor and opposition. If this latter springs from pride it is abominable; if from bad breeding it is despicable. Better too much courtesy than too little, provided it is not the same for all, which degenerates into injustice. Between opponents it is especially due as a proof of valor. It costs little and helps much: everyone is honored who gives honor. Politeness and honor have this advantage, that they remain with him who displays them to others.
