Before Seneca and Marcus Aurelius could emerge—figures the world still admires today—as well as early Christianity, there had to exist a brilliant mind capable of turning life’s shipwreck into a beautiful transformation. That mind belonged to Zeno of Citium
Some ancient philosophies leap through centuries and millennia with ease, landing in our present as if the time between were just a pause. Naturally, there’s something in our current reality that makes us receptive to ancient wisdom.
If modern life weren’t so difficult and unpredictable, would ancient ideas that help ease such burdens resonate as strongly? Stoicism is the ultimate idea for bearing any burden.
In our era of permanent technological revolution, it is the stress of constant change that so often knocks us off balance. Nearly all ancient philosophers, from East to West, taught that change is unstoppable and constant. That’s true—but in their time, change had a rhythm and was somewhat predictable. Seasons changed and returned, people lived and died, but followed a more foreseeable trajectory.
Today, we face extreme unpredictability. Alongside the fundamental uncertainties—fate’s daily surprises, for better or worse—we now have many new ones. We don’t know if our jobs are permanent, and by extension, our identity.
Moreover, the value systems we supposedly live by are in a constant, accelerating whirlpool of change—either we adapt or let frustration consume us. Yes, there are securities we take for granted compared to ancient times. We don’t fear for basic necessities as they did. Food is plentiful—if we can afford it. Yet with each security comes modern insecurity: is our food healthy? Is our home truly safe, or could a financial mistake cost us everything?
It’s no wonder, then, that some old philosophies are experiencing a strong comeback and even a renaissance. Stoicism, in particular, has been so widely promoted in recent years that it’s at risk of becoming a buzzword, much like “mindfulness”—a cognitive practice rooted in Buddhist teachings.
In fact, stoicism is so (re)popularized today that you’ve likely already heard wise sayings from the “superheroes” of stoicism like Seneca, Epictetus, and Emperor Marcus Aurelius. Their wisdom is profound—but how did stoicism begin? How was this philosophy, which they and others refined to perfection, originally formed?
Stoicism is a deeply important life approach that teaches us that the weight of our problems lies not in the problems themselves but in how we respond to them. All humans imagine catastrophic scenarios and exaggerate difficulties. “You suffer more in imagination than in reality,” Seneca once said. That single line could demystify so much human suffering that, in a better world, it would be required learning.
Roman Emperor Marcus Aurelius elevated stoicism to even greater practical heights in his book Meditations (his personal journal), showing how we can view even the worst moments from a higher, bird’s-eye perspective—and see how much of our pain is confined within the limits of our own minds.
But for the great stoics to build upon any foundation, the first stoic idea had to emerge. That brilliant notion—that a person can become indestructible by not giving adversity more importance than necessary, that suffering exists only if we perceive it as such—had to be born in someone’s mind.
So let’s return to the beginning. It’s time to meet the first stoic, the one who created a philosophy that has never faded. His name was Zeno of Citium, and as his name suggests, he came from the ancient city of Citium on the island of Cyprus. He lived between 336 and 264 BCE. His life was as inspiring as the philosophy he created—and as we’ll soon see, it was created almost by accident.
Unlike many other famous philosophers, Zeno came from a very different background. He wasn’t destined for philosophy—he was born into a wealthy merchant family from Cyprus. Historians still debate whether his family were Greeks or Phoenicians (or both), as both groups lived in Cyprus.
Young Zeno inherited his father’s trade business and was deeply involved in it. He often traveled by ship with his father on trade missions, learning about commerce and navigation, and encountering diverse people and cultures—all of which sharpened his mind.
While traveling the Mediterranean, he certainly encountered various philosophical ideas, but didn’t pursue them deeply. He had little time—being a successful merchant required focus. They traded olive oil and wine from Greece, grain from Egypt, copper and silver from Cyprus, textiles from Phoenicia…
In his late twenties or early thirties, something happened that changed his life forever. Zeno had sailed the Mediterranean many times. He knew the job was risky. If he lost his ship and its valuable cargo, his entire livelihood would be in jeopardy.
And then it happened: a violent storm wrecked his ship and it sank, along with all the goods. Zeno barely survived and eventually reached Athens (we don’t know the exact location of the wreck, but it must’ve been near Athens).
He arrived with nothing but torn clothes—once a promising young merchant, now penniless. How could he start over without his inherited ship? It seemed fate had cruelly sabotaged him just as he was reaching success.
Wandering in search of comfort, he ended up in a library, where he randomly picked up a book about Socrates. He already knew of Socrates, but now it struck a deeper chord—perhaps due to his own dire situation. Curious, he asked the bookseller where to find men like Socrates. The seller pointed to a man walking out: “That’s Crates of Thebes, a famous Cynic philosopher.” Zeno ran after him—and fate took over.
This shipwrecked young man, thinking his life had sunk along with his cargo, had just found his teacher. That moment would echo through history.
Crates was a key figure in the Cynic school of philosophy, founded by Diogenes (who had been his teacher). The Cynics believed in radical simplicity—”own little, and reduce even that.” They promoted a life of scarcity in harmony with nature.
Given Zeno’s sudden loss of everything, the idea that meaning could be found in his “new poverty” made a deep impression.
Zeno became a devoted student of Crates, but he didn’t stop there. Crates was his introduction to philosophy. He later studied other schools, including Plato’s followers. Yet none fully aligned with his evolving thoughts. Over time, he began to synthesize his own philosophy.
Around 300 BCE, at about 36 years old, Zeno began teaching his own ideas at a place called the Stoa Poikile—the “Painted Porch”—in Athens.
As you might guess, this gave the Stoic school its name.
The Stoa Poikile was a covered walkway or colonnade, common in Greek cities. “Poikile” means “painted,” referring to the elaborate frescoes on the walls depicting Greek myths and historical scenes like the Battle of Marathon.
Here, Zeno began teaching. He and his followers gathered in the Stoa Poikile to discuss philosophy, and from these meetings, Zeno’s school—originally unnamed—came to be known as Stoicism.
Zeno’s teachings emphasized living in harmony with nature—an idea inherited from his mentors—while also adding self-control and the pursuit of virtue as the highest good. His philosophy was practical, aimed at helping people live better lives by understanding the natural order and their role within it.
Zeno lived by the principles he taught. Known for his modesty, he led a simple life, embodying stoic virtues like self-discipline, rationality, and frugality. Unlike other philosophers who may have sought wealth or power, Zeno was content with little and admired for his integrity and wisdom. He was so respected that, upon his death, the citizens of Athens honored him with a golden wreath on his tomb—an exceptional tribute for a philosopher.
Instead of despairing over misfortune, Zeno saw his shipwreck as a chance to begin anew. He later famously said that his shipwreck was the best thing that ever happened to him—because it led him to philosophy. This perfectly reflects the stoic idea that challenges are opportunities for growth and self-improvement.
Because later thinkers like Seneca and Marcus Aurelius so refined stoic ideas, Zeno’s name has faded somewhat from memory—which is a shame.
Zeno of Citium’s impact on Stoicism was foundational. Without his teachings, it’s unlikely Seneca or Marcus Aurelius could have developed their philosophies as they did. Zeno laid out the core principles: virtue, rationality, and living in accordance with nature. These became the backbone of Stoic thought, later expanded by others. Yet we must give credit to the one who first realized that we must fully accept what we cannot change—and instead focus on what we can.
Zeno was the first to fully grasp this—and it’s as relevant now as it was then.
What can we change, really? Only what lies within our control. And what is that? Very little. We cannot change other people (much as we’d like to). We cannot control whether today is sunny or rainy. No matter how hard we try, we can’t even fully control what happens to our own bodies. We can aim to live healthily, but to think we can prevent every illness is unrealistic. The only true control we have is over our thoughts—how we interpret what happens.
If that’s true, why not use it fully? Even the greatest catastrophe is a matter of perception. To the Stoics, no situation exists that cannot be viewed from a different perspective.
Things could have turned out differently. Zeno might have narrowly avoided the storm. Had that happened, he would’ve looked at the wild sea from afar, relieved. He would never have guessed that the storm was meant to be his greatest teacher—his deep transformation—from a successful merchant into a man capable of altering human history.
That’s no exaggeration, especially when we consider how much Stoicism influenced early Christianity.
Yes—Stoicism significantly shaped early Christian ethics and ideas about God, virtue, and the soul.
The Stoics believed in the Logos, a rational principle that governs the universe. They saw it as divine reason, a unifying force present in all people. Early Christian theologians adopted this idea, interpreting Logos as the “Word of God.” In the Gospel of John, Jesus is described as the Logos—the divine reason through which the world was created. This concept became central to Christian theology.
The Stoics also emphasized living in harmony with nature and reason, and cultivating virtues such as wisdom, courage, justice, and self-control. For them, virtue was the highest good, and external circumstances like wealth or status were indifferent to a “good life.” Christian ethics absorbed these ideas, prioritizing inner moral integrity over outer success. The Stoic notion of living in accordance with nature was reinterpreted in Christianity as living in accordance with God’s will. Even Christian teachings on humility, patience, and self-denial reflect Stoic values of self-mastery and indifference to externals.
Stoics taught that suffering and adversity are opportunities to practice virtue and develop inner strength. They believed true happiness comes from maintaining inner peace despite outer turmoil. This Stoic understanding of suffering influenced Christian teachings on the redemptive nature of suffering. Early Christians were encouraged to endure persecution and hardship with patience and faith, viewing such trials as a path toward closeness with God and spiritual maturity.
All these similarities are no surprise when you consider just how influential Stoicism was in its time…
