Horse-play, romping, frequent and loud fits of laughter, jokes, and indiscriminate familiarity, will sink both merit and knowledge into a degree of contempt. They compose at most a merry fellow; and a merry fellow was never yet a respectable man.
Lord ChesterfieldIn order to judge of the inside of others, study your own; for men in general are very much alike; and though one has one prevailing passion, and another has another, yet their operations are much the same; and whatever engages or disgusts, pleases or offends you, in others, will, mutatis mutandis, engage, disgust, please, or offend others, in you.
Lord ChesterfieldPleasure is a necessary reciprocal. No one feels, who does not at the same time give it. To be pleased, one must please. What pleases you in others, will in general please them in you.
Lord ChesterfieldLet your enemies be disarmed by the gentleness of your manner, but let them feel at the same time the steadiness of your just resentment for there is a great difference between bearing malice, which is always ungenerous, and a resolute self-defense which is ever prudent and justifiable.
Lord Chesterfield
