The Meditations of Marcus Aurelius

Meditations ("thoughts/writings addressed to himself") is a series of personal writings by Marcus Aurelius, Roman Emperor 161-180 CE, setting forth his ideas on Stoic philosophy.

Marcus Aurelius wrote the 12 books of the Meditations in "highly-educated" Koine Greek as a source for his own guidance and self-improvement. It is possible that large portions of the work were written at Sirmium, where he spent much time planning military campaigns from 170 to 180. Some of it was written while he was positioned at Aquincum on campaign in Pannonia, because internal notes tell us that the second book was written when he was campaigning against the Quadi on the river Granova (modern-day Hron) and the third book was written at Carnuntum. It is not clear that he ever intended the writings to be published, so the title Meditations is but one of several commonly assigned to the collection. These writings take the form of quotations varying in length from one sentence to long paragraphs.

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."
