It is not without good reason said, that he who has not a good memory should never take upon him the trade of lying. – Michel de Montaigne, translated from French

Always telling the truth is no doubt better than always lying, although equally pathological. – Robert Brault, rbrault.blogspot.com

You shall not steal, nor deal falsely, nor lie to one another. Leviticus 19:11 – Bible

If falsehood, like truth, had but one face, we would be more on equal terms. For we would consider the contrary of what the liar said to be certain. But the opposite of truth has a hundred thousand faces and an infinite field. – Michel Eyquem de Montaigne
