A man of the best parts and greatest learning, if he does not know the world by his own experience and observation, will be very absurd, and consequently very unwelcome in company. He may say very good things; but they will be probably so ill-timed, misplaced, or improperly addressed, that he had much better hold his tongue.
Lord ChesterfieldExperience only can teach men not to prefer what strikes them for the present moment, to what will have much greater weight with the them hereafter.
Lord ChesterfieldNever seem wiser, nor more learned, than the people you are with. Wear your learning, like your watch, in a private pocket: and do not merely pull it out and strike it; merely to show that you have one.
Lord Chesterfield
