0Written in Greek, without any intention of publication, by the only Roman emperor who was also a philosopher, the Meditations of Marcus Aurelius (AD 121-180) offer a remarkable series of challenging spiritual reflections and exercises developed as the emperor struggled to understand himself and make sense of the universe. Ranging from doubt and despair to conviction and exaltation, they cover such diverse topics as the nature of moral virtue, human rationality, divine providence, and Marcus' own emotions.
