There is one essential point wherein a political liar differs from others of the faculty, that he ought to have but a short memory, which is necessary according to the various occasions he meets with every hour of differing from himself and swearing to both sides of a contradiction, as he finds the persons disposed with whom he has to deal. In describing the virtues and vices of mankind, it is convenient, upon every article, to have some eminent person in our eye, from whom we copy our description. I have strictly observed this rule, and my imagination this minute represents before me a certain great man famous for this talent, to the constant practice of which he owes his twenty years' reputation of the most skilful head in England for the management of nice affairs. The superiority of his genius consists in nothing else but an inexhaustible fund of political lies, which he plentifully distributes every minute he speaks, and by an unparalleled generosity forgets, and consequently contradicts, the next half-hour. He never yet considered whether any proposition were true or false, but whether it were convenient for the present minute or company to affirm or deny it; so that, if you think fit to refine upon him by interpreting everything he says, as we do dreams, by the contrary, you are still to seek, and will find yourself equally deceived whether you believe or not: the only remedy is to suppose that you have heard some inarticulate sounds, without any meaning at all; and besides, that will take off the horror you might be apt to conceive at the oaths wherewith he perpetually tags both ends of every proposition; although, at the same time, I think he cannot with any justice be taxed with perjury when he invokes God and Christ, because he has often fairly given public notice to the world that he believes in neither. Some people may think that such an accomplishment as this can be of no great use to the owner, or his party, after it has been often practised and is become notorious; but they are widely mistaken. 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. Falsehood 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.
