The Roman Emperor Marcus Aurelius was one of the most prominent and lofty adherents of stoicism, a philosophy characterized in part by moral worth and tranquility of mind. In his most famous work, the influential and eminently quotable “Meditations,” Marcus Aurelius recorded his private thoughts on stoic wisdom, life, nature and, fundamentally, how to be a good person. For him, it was far more important to actually act in accordance with your values, rather than simply arguing what those values should be. While philosophical discussions about morality have their place, we must also try to simply be good and virtuous in our own actions.
