Liar Quotes - page 11
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.
Jonathan Swift
An untruth must be spoken, where need requires. For whether men lie, or say true, it is with one and the same object. Men lie, because they think to gain by deceiving others; and speak the truth, because they expect to get something by their true speaking, and to be trusted afterwards in more important matters. Thus, though their conduct is so opposite, the end of both is alike. If there were no gain to be got, your true-speaking man would tell untruths as much as your liar, and your liar would tell the truth as much as your true-speaking man.
