Marcus Aurelius

Marcus Aurelius Antoninus was born in Rome on April 26, 121 AD, the child of a wealthy patrician family closely connected to the imperial court. His father died when he was a toddler. His grandfather raised him. As a teenager, Marcus was noticed by the reigning emperor Hadrian, who set him on a path to the throne: he was adopted by Hadrian’s chosen successor, Antoninus Pius, in 138 AD, with the understanding that he would eventually rule.

He did not want it. Marcus had been drawn to philosophy from boyhood — he studied with the best Stoic teachers of his time, wore the rough woolen cloak of a philosopher rather than imperial silk, and slept on the floor as a student until his mother made him stop. But duty was the core Stoic virtue. When his adoptive father died in 161 AD, Marcus took the throne — sharing it, unusually, with his adoptive brother Lucius Verus as co-emperor.

He ruled for nineteen years. Most of them were consumed by war. The Parthian Empire invaded in the east. Germanic tribes crossed the Danube in the north. A plague swept through the empire, killing millions, including Lucius Verus himself. Marcus spent the last decade of his life in a military camp on the Danube frontier, personally commanding the legions in campaigns against the Marcomanni, Quadi, and Sarmatians. He never returned to Rome.

It was during those campaigns that he wrote the book we now call Meditations. He never titled it. He never intended for it to be read. He called it simply “To Himself” — ta eis heauton in Greek — and wrote it in the language of the philosophers rather than the Latin of the empire. The entries are short, sometimes brutal, almost always addressed to himself in the second person: “When you rise in the morning, think of what a precious privilege it is to be alive — to breathe, to think, to enjoy, to love.”

Marcus died on March 17, 180 AD, in military quarters near the modern city of Vienna. He was 58. The historian Cassius Dio wrote that his death ended the golden age of Rome: “Our history now descends from a kingdom of gold to one of iron and rust.” Gibbon, seventeen centuries later, called the reigns of Marcus and his four predecessors the happiest period in the history of the human race.

The private journal survived. Copied, translated, copied again across centuries and languages and empires that rose and fell. It reached the modern West in 1558 with its first printed Greek edition. It has never been out of print since. Meditations sits today on the nightstands of NFL coaches, Navy SEALs, startup founders, and philosophy students the world over. Every modern stoic teacher — Ryan Holiday, Tim Ferriss, William Irvine, Donald Robertson — traces their work back to this one book written by an emperor who was trying, on hard nights in cold tents on a distant frontier, to remind himself how to be a decent human being.

Marcus’s central teaching was not grand: the obstacle in front of you is the work. What stands in the way becomes the way. You do not control events, but you do control your response to them. Duty is a privilege, not a burden. Memento mori — remember you will die — so live now, and live well.
