Laudator Temporis Acti

Jonathan Swift (1667-1745), The Examiner, No. 15 (November 9, 1710; an "Essay upon the Art of Political Lying"):

I have been sometimes thinking, if a man had the art of the second sight for seeing lies, as they have in Scotland for seeing spirits, how admirably he might entertain himself in this town, by observing the different shapes, sizes, and colours of those swarms of lies which buzz about the heads of some people, like flies about a horse's ears in summer; or those legions hovering every afternoon in Exchange-alley, enough to darken the air; or over a club of discontented grandees, and thence sent down in cargoes to be scattered at elections.

Id. (on Thomas Wharton):

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.

Id.:

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 further 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.

Considering that natural disposition in many men to lie, and in multitudes to believe, I have been perplexed what to do with that maxim so frequent in everybody's mouth, that truth will at last prevail. Here has this island of ours, for the greatest part of twenty years, lain under the influence of such counsels and persons, whose principle and interest it was to corrupt our manners, blind our understanding, drain our wealth, and in time destroy our constitution both in church and state, and we at last were brought to the very brink of ruin; yet by the means of perpetual misrepresentations, have never been able to distinguish between our enemies and friends.
