Marcus Aurelius Quotes
For nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquility; and I affirm that tranquility is nothing else than the good ordering of the mind.
Aurelius, Marcus. The Meditations of the Emperor Marcus Antoninus. Translated by George Long, A. L. Burt, 1890, p. 131.
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.
