“The most common sort of lie is that by which a man deceives himself: the deception of others is a relatively rare offense.”
― Friedrich Nietzsche, The Anti-Christ

“Now, to be sure, Mrs Varden thought, here is a perfect character. Here is a meek, righteous, thoroughgoing Christian, who, having mastered all these qualities, so difficult of attainment; who, having dropped a pinch of salt on the tails of all the cardinal virtues, and caught them everyone; makes light of their possession, and pants for more morality. For the good woman never doubted (as many good men and women never do), that this slighting kind of profession, this setting so little store by great matters, this seeming to say, ‘I am not proud, I am what you hear, but I consider myself no better than other people; let us change the subject, pray’—was perfectly genuine and true. He so contrived it, and said it in that way that it appeared to have been forced from him, and its effect was marvellous.

Aware of the impression he had made—few men were quicker than he at such discoveries—Mr Chester followed up the blow by propounding certain virtuous maxims, somewhat vague and general in their nature, doubtless, and occasionally partaking of the character of truisms, worn a little out at elbow, but delivered in so charming a voice and with such uncommon serenity and peace of mind, that they answered as well as the best. Nor is this to be wondered at; for as hollow vessels produce a far more musical sound in falling than those which are substantial, so it will oftentimes be found that sentiments which have nothing in them make the loudest ringing in the world, and are the most relished.”
― Charles Dickens, Barnaby Rudge

“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 hath had its effect: like a man, who hath thought of a good repartee when the discourse is changed, or the company parted; or like a physician, who hath found out an infallible medicine, after the patient is dead.”
― Jonathan Swift

“Thou of thyself thy sweet self dost deceive.”
