Confess you were wrong yesterday; it will show you are wise today. – Proverb

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

It is always the best policy to tell the truth, unless, of course, you are an exceptionally good liar. – Jerome K. Jerome
