The second century CE Roman emperor Marcus Aurelius was also a Stoic philosopher, and his private Meditations, written in Greek, gives readers a unique opportunity to see how an ancient person (indeed an emperor) might try to live a Stoic life, according to which only virtue is good, only vice is bad, and the things which we busy ourselves with are all indifferent. The difficulties Marcus faces putting Stoicism into practice are philosophical as well as practical, and understanding his efforts increases our philosophical appreciation of Stoicism.
