Meditations (Medieval Greek: Τὰ εἰς ἑαυτόν Ta eis heauton, literally "things to one's self") is a series of personal writings by Marcus Aurelius, Roman Emperor from 161 to 180 AD, recording his private notes to himself and ideas on Stoic philosophy.
Marcus Aurelius wrote the 12 books of the Meditations in 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 first book was written when he was campaigning against the Quadi on the river Granova (modern-day Hron) and the second book was written at Carnuntum.
"When you wake up in the morning, tell yourself: The people I deal with today will be meddling, ungrateful, arrogant, dishonest, jealous, and surly. They are like this because they do not know how to tell good from evil. But I... have recognized that the wrongdoer has a nature related to my own." This and other useful affirmations from the second century Stoic philosopher and Roman emperor Marcus Aurelius have been retranslated for the first time in 35 years by Hays, classics professor at the University of Virginia. He includes an introduction that sketches the life of Aurelius and also summarizes the principles of Stoicism.
