Marcus Aurelius: Stoic Self-Mastery as a Path to Yourself

Marcus Aurelius (121–180 CE) was Roman emperor from 161 and, together with Seneca and Epictetus, is one of the great Stoics of the Roman imperial era. His Meditations aren't a textbook but notes to himself: the admonitions, doubts and exercises of a man who ruled an empire and still kept working on himself.

At their center is an idea that appeals to many people again today: self-mastery doesn't mean suppressing feelings but clarifying your own judgment. Between what happens and what you make of it there is a space, and that space is yours to use.

The Meditations: Notes to Himself

Marcus wrote in Greek, the language of philosophy in Rome. The title that has come down to us is “Ta eis heauton”, “To Himself”; in English the work is known as the Meditations. The twelve books were probably not meant for publication, and parts of them were written in army camps on the Danube during the wars against the Marcomanni and the Quadi. The first book is a kind of list of thanks: Marcus records what he learned from his family, teachers and friends.

That is exactly what makes the notes so accessible. Nobody is preaching from a pulpit here; this is a person reminding himself of his own resolutions, often several times and in ever new words.

What the Stoics Mean by Self-Mastery

Stoicism knows four cardinal virtues: wisdom, justice, courage and moderation (sophrosyne), under which it also counts self-control. What is meant is not harshness toward yourself but clarity about who makes the decisions inside you. Marcus speaks of the ruling part of the soul, the hegemonikon, which examines impressions before it assents to them.

His basic idea comes up again and again, roughly: if something external troubles you, it isn't the thing itself that disturbs you but your judgment about it, and that judgment you can change (Meditations VIII, 47). Elsewhere he writes that the soul takes on the color of its thoughts. So whoever examines their thoughts shapes their character.

What Is in Your Power

At the heart of Stoic practice is a distinction with which Epictetus's Handbook opens: some things are in our power, others are not. Marcus knew Epictetus's teaching; in the first book he thanks his teacher Rusticus for giving him notes of Epictetus's discourses to read. In our power are judgments, intentions and reactions; not in our power are other people's behavior, our reputation or the course of the world.

That sounds simple and is hard. If you cling to what you can't control, you wear yourself out. If you direct your strength to where you can really make a difference, you gain calm and the ability to act at the same time. Marcus puts this into an image: be like the headland against which the waves break without end; it stands firm, and around it the surf grows calm.

Observing Feelings Instead of Suppressing Them

A common misunderstanding is that the Stoics were unfeeling. But Stoicism distinguished between the first stirring, which comes involuntarily, such as flinching at bad news, and the passion that arises when we assent to a hasty judgment. The first is human. With the second, the work begins: noticing the feeling, naming it and examining which judgment lies within it.

That is close to what psychology today calls self-regulation. Marcus notes, for example, that the best way to take revenge is not to become like the one who wrongs you. If you are constantly overwhelmed by feelings, you will find food for thought in Stoicism, but no substitute for medical or psychotherapeutic advice. More on this in the article Self-Regulation and Personality.

Four Stoic Exercises for Everyday Life

1. Preparing for the Day

The second book opens with a morning exercise, roughly: tell yourself first thing in the morning that today you will meet meddling, ungrateful, arrogant and envious people. They are like this because they can't tell good from bad; they cannot harm you, and we are born to work together, like hands and feet. If you prepare yourself like this, friction surprises you less and you meet it more calmly.

2. Thinking Through Difficulties in Advance

The Stoics practiced becoming aware of possible losses and obstacles in advance; the exercise is known as praemeditatio malorum. The aim isn't fear but composure and gratitude for what is here now. Marcus reminds himself again and again of transience: Alexander the Great and his mule driver, he notes, were made equal by death.

3. Retreating into Yourself

People look for retreats in the country, by the sea or in the mountains, Marcus writes, yet you can withdraw into yourself at any time. A few quiet minutes in which you sort through your judgments are such a retreat. And instead of talking about virtue, he admonishes himself briefly elsewhere: stop talking about what a good person should be like, and be one.

4. Taking Stock in the Evening

The evening review doesn't come from Marcus; Seneca describes it in his essay on anger, following the example of the philosopher Sextius. Before going to sleep, he asked himself, roughly: which bad habit did I give up today? Which fault did I resist? In what way have I become better? If you write a few lines about it, you do as Marcus did and write not for others but for yourself. You can read more about Seneca in the article Seneca: On the Shortness of Life.

Stoicism and Personality Systems

Personality systems and Stoicism complement each other: the systems show you the terrain, and Stoic practice gives you the tools to move through it. The Enneagram describes a basic fear for each type and a typical reaction to what can't be controlled. In Human Design, the not-self themes such as frustration or bitterness count as signals that you are acting against your nature. In the Stoic sense, both are an invitation to examine your own judgment. You'll find a more detailed comparison in the article Stoicism and Self-Knowledge, and a related practice of daily self-examination from China in the teachings of Confucius.

Frequently Asked Questions about Marcus Aurelius

What are the Meditations of Marcus Aurelius?

The Roman emperor's private notes, written in Greek and divided into twelve books. They were probably not intended for the public and are regarded today as a central work of late Stoicism.

What does Stoicism teach about self-mastery?

That self-mastery isn't the suppression of feelings but clarity about your own judgment. It isn't the event that determines your reaction but the judgment you attach to it, and that is in your power.

How can I apply Stoic principles in everyday life?

Ask yourself in the morning what you can and can't influence today. When you're angry, pause briefly and examine your judgment before you respond. And in the evening, write down what went well and which reaction you want to handle differently next time.

Which edition of the Meditations is a good place to start?

In German there are inexpensive editions, for example from Reclam, and bilingual editions with the Greek text. In English, Gregory Hays's translation is considered especially accessible.

Is Stoicism only for controlled, rational types?

No. Emotional people in particular can find support in Stoic practice, because it creates distance from the first stirring without devaluing what they experience. Stoicism doesn't aim to make you unfeeling but free from passions that arise from hasty judgments.
