How to Think Like a Roman Emperor

Marcus Aurelius ruled the Roman Empire from 161 to 180 A.D., a time of wars on the frontiers, a devastating epidemic, and betrayals within his own court. In the middle of all that, he found time to write private notes in Greek, which centuries later came to be known as the Meditations. They were not texts for the public. They were reminders from a man trying to stay decent under pressure.

Donald Robertson uses this figure as the guiding thread of the book. He is a psychotherapist trained in cognitive behavioral therapy and a scholar of Stoicism, the philosophical school Marcus Aurelius followed. The proposal is twofold: to tell the emperor's life story and to show, step by step, how Stoic practices can be used today to deal with fear, anger, grief, and discouragement.

The premise is that Stoicism was never just theory. It was a daily training of the mind, something closer to a gymnasium for thought than to a library. Anyone who picks up the book expects to learn how to live better, not merely to quote catchy lines. That practical focus is the book's great appeal.

The book explains that the Stoics did not separate philosophy from routine. For them, philosophizing meant training judgment, desires, and actions in the face of real events. Robertson draws on the historian Pierre Hadot, who described ancient philosophy as a set of spiritual exercises, repeated until they became habit.

This changes the reading. Instead of debating abstract ideas, the Stoic asks: how do I react when the bus is late, when my boss humiliates me, when a relative falls ill? Philosophy becomes a tool for those moments. And like any tool, it only works if it is used and trained before the emergency.

In everyday American life, think of someone who decides, before walking into a tense meeting, how they intend to respond if they are criticized. Or of someone who practices breathing before calling an angry customer. The logic is that of an athlete who rehearses the move until the body reacts on its own. Here, the rehearsal is mental and emotional.

At the center of Stoic ethics is the idea that the only true good is character, expressed in four virtues. Wisdom is knowing how to distinguish what is good, bad, and indifferent. Justice is treating others with fairness and a sense of community. Courage is acting rightly despite fear. Moderation is mastering your own impulses and desires.

Robertson shows that Marcus Aurelius used these virtues as a compass. Faced with a decision, he would ask himself which action would be wisest, most just, most courageous, and most moderate. This does not eliminate the difficulty of the choice, but it offers criteria that go beyond what brings the most profit or the least discomfort.

It is a good exercise in practical ethics. In a common dilemma, such as reporting a coworker's mistake or staying silent to avoid trouble, the four questions help organize your thinking. The book does not claim the answer is easy, only that there is a path more consistent with the person you want to be.
