Marcus Aurelius Quotes
Outward objects cannot take hold of the soul, nor force their passage into her, nor set any of her wheels going. No, the impression comes from herself, and it is her own motions which affect her. As for the contingencies of fortune, they are either great or little, according to the opinion she has of her own strength.
Aurelius, Marcus. The Emperor Marcus Antoninus His Conversation with Himself. Translated by Jeremy Collier, Richard Sare, 1701, bk. 5, sec. 19.
Marcus Aurelius Antoninus was Roman emperor from 161 to 180 and a Stoic philosopher. He was the last of the rulers known as the Five Good Emperors (a term coined some 13 centuries later by Niccolò Machiavelli), and the last emperor of the Pax Romana (27 BC to 180 AD), an age of relative peace and stability for the Roman Empire. He served as Roman consul in 140, 145, and 161.
