Meditations by Marcus Aurelius
Meditations is the writings of Marcus Aurelius on Stoic philosophy. His stoic ideas often involve avoiding indulgence in sensory affections, a skill which, he says, will free a man from the pains and pleasures of the material world. He claims that the only way a man can be harmed by others is to allow his reaction to overpower him. An order or logos permeates existence. Rationality and clear-mindedness allow one to live in harmony with the logos. This allows one to rise above faulty perceptions of "good" and "bad."
