The Enduring Wisdom of Marcus Aurelius: “Our life is what our thoughts make it”
Marcus Aurelius, the Roman Emperor who ruled from 161 to 180 CE, stands as one of history’s most compelling figures precisely because of his profound internal contradictions. Born into incomparable privilege and power, he spent his reign wrestling with doubt, anxiety, and the weight of his responsibilities. Unlike most political leaders throughout history, Marcus Aurelius documented his inner struggle in a series of personal writings never intended for public consumption. These reflections, later compiled as “Meditations,” reveal a man who sought not validation or glory but rather a path to virtue and inner peace. The quote “Our life is what our thoughts make it” encapsulates the central philosophy that animated his reign and continues to inspire millions more than eighteen centuries after his death. Understanding this statement requires us to step into Marcus Aurelius’s world—a world of constant warfare, plague, administrative chaos, and personal grief—yet also a world where one man chose to master his mind rather than his circumstances.
The context in which Marcus Aurelius developed this philosophy is essential to understanding its authenticity. He inherited the throne during a period of crisis, facing military threats on multiple frontiers, particularly from Germanic tribes pressing against the Rhine and Danube borders. Simultaneously, the Antonine Plague swept through the Roman Empire, killing millions and creating unprecedented social disruption. As emperor, Marcus Aurelius spent much of his reign in military camps away from Rome, conducting arduous campaigns against barbarian invaders while his beloved empire suffered from within. Yet even more personally devastating, he endured the loss of numerous children—a common tragedy of the era but no less agonizing for a father. Unlike an emperor who might seek refuge in excess or distraction, Marcus Aurelius turned inward, using his solitude in military camps to examine his thoughts, emotions, and the nature of virtue itself. The Meditations were written during these campaigns, not in peaceful contemplation but amid genuine suffering and uncertainty, which gives the philosophy contained within them remarkable credibility.
Marcus Aurelius was born in 121 CE into a wealthy, aristocratic family with deep political connections. His biological father held the position of praetor, and his family was part of Rome’s ruling elite. However, his father died when Marcus was quite young, and he was raised primarily by his grandfather, also named Marcus Aurelius. The young Marcus received an exceptional education, studying rhetoric, philosophy, and Greek along with Latin—the latter being unusual for a young Roman nobleman, as many still viewed Greek as a foreign language despite centuries of Roman-Greek cultural exchange. His formal philosophical training came under several Stoic philosophers, particularly Rusticus, whose influence shaped Marcus Aurelius’s worldview profoundly. What many people don’t realize is that Marcus Aurelius was not always destined for the throne. The previous emperor, Antoninus Pius, had no surviving sons, and Marcus Aurelius was essentially selected as the most worthy successor—a choice that suited neither his temperament nor his desires. Throughout his life, Marcus Aurelius repeatedly expressed reluctance about his imperial role, a humility that paradoxically made him more suited to the position than someone who craved it.
The philosophy underlying “Our life is what our thoughts make it” derives from the Stoic tradition, which held that virtue and inner peace come not from controlling external circumstances but from controlling one’s judgments about those circumstances. The Stoics taught that while we cannot control events that happen to us, we have absolute control over our responses to them. This distinction—between what is “up to us” and what is “not up to us”—formed the cornerstone of Stoic practice. When Marcus Aurelius wrote these words, he was grappling with this precise truth: that his circumstances as emperor, his losses, his fears, and his physical ailments were largely beyond his control, but his thoughts about them were entirely within his power. The Stoics didn’t advocate for emotional suppression or denial. Rather, they encouraged rational examination of thoughts and deliberate cultivation of attitudes that align with virtue. In Marcus Aurelius’s case, this meant constantly reminding himself that external things—wealth, status, reputation, even health—were ultimately indifferent to true human flourishing. What mattered was how one thought about them, how one responded to them, and whether one maintained virtue in the face of adversity.
A lesser-known aspect of Marcus Aurelius’s life is his complicated relationship with his own philosophical ideals. While he preached the Stoic virtues of acceptance and non-attachment to worldly concerns, he was a man of flesh and blood who struggled with these ideals daily. His journal-like reflections often read as a man reminding himself of truths he intellectually understood but emotionally struggled to internalize. This vulnerability is actually what makes his writing so powerful and so relevant to modern readers. He wasn’t a detached sage dispensing wisdom from an ivory tower; he was a powerful man wrestling with the same anxieties, resentments, and despairs that afflict ordinary people. Additionally, Marcus Aurelius was married to Faustina, and while Roman historians have sometimes portrayed her negatively, modern scholarship suggests she was a capable partner who gave him many children and supported his reign. Yet even in his marriage and family life, Marcus Aurelius experienced profound disappointment and loss, as so many of his children predeceased him. These personal griefs inform the poignancy of his philosophical reflections.
