Few lies carry the inventor's mark, and the most prostitute enemy to truth, may spread a thousand without being known for the author: besides, as the vilest writer has his readers, so the greatest liar has his believers: and it often happens, that if a lie be believed only for an hour, it has done its work, and there is no farther occasion for it. Falshood flies, and truth comes limping after it; so that when men come to be undeceived, it is too late; the jest is over, and the tale has had its effect: like a man, who has thought of a good repartee, when the discourse is changed, or the company parted; or like a physician, who has found out an infallible medicine, after the patient is dead.
