"Doth some one say that there be gods above? There are not; no, there are not. Let no fool, Led by the old false fable, thus deceive you. Look at the facts themselves, yielding my words, No undue credence: for I say that kings kill, rob, break oaths, lay cities waste by fraud, And doing thus are happier than those, Who live calm pious lives day after day. All divinity is built-up from our good and evil luck."
