Section 18
1When a raven croaks inauspicfously, let not the external impression carry you away, but straightway draw a distinction in your own mind, and say, "None of these portents are for me, but either for my paltry body, or my paltry estate, or my paltry opinion, or my children, or my wife. But for me every portent is favourable, if I so wish; for whatever be the outcome, it is within any power to derive benefit from it."
