Things themselves cannot touch the soul, not in the least degree, nor have they admission to the soul nor can they turn or move the soul: it turns and moves itself alone and whatever judgment it may think proper to make, such it makes by remaking for itself the things that present themselves to it
Marcus AureliusWhich is recorded of Socrates, that he was able both to abstain from, and to enjoy, those things which many are too weak to abstain from, and cannot enjoy without excess. But to be strong enough both to bear the one and to be sober in the other is the mark of a man who has a perfect and invincible soul.
Marcus AureliusFrom Apollonius I learned freedom of will and undeviating steadiness of purpose; and to look to nothing else, not even for a moment, except to reason.
Marcus AureliusWhen men are inhuman, take care not to feel towards them as they do towards other humans.
