Transcript
- Luna: So, we've talked about Marcus as a warrior, a reformer, a plague-stricken emperor. But I've heard whispers he once tried to build a city of philosophers. Is that true? Lucas: It is, and it's one of those details that makes you stop and think about who Marcus Aurelius really was. In the midst of the Marcomannic Wars, while he was camped on the Danube at Carnuntum, he apparently started sketching out a plan for a city—a colony of philosophers, inspired by Plato's Republic. Lucas: The main source is the Historia Augusta, which is always a bit suspect, but it's corroborated in scattered references elsewhere—Fronto's letters mention it with cautious enthusiasm, and Cassius Dio notes that Marcus had this 'dream of a commonwealth of sages.' He wanted to call it something like 'Philosophopolis' or 'Civitas Philosophorum.' Luna: Wait—so an actual physical city, not just a metaphor? Lucas: Yes, a real city. He envisioned it as a place where Stoic philosophers and their families would live under laws derived from Stoic ethics—no private property, shared governance by the wisest, education for all children in logic and ethics. He even started identifying a location near Carnuntum, on the Danube frontier, right in the middle of a war zone. Lucas: Now, the timing matters. This was around 171 to 172 AD. The Marcomannic Wars were at their peak, the Antonine Plague was decimating the army, and Marcus was personally leading campaigns. Yet he's thinking about building a utopia. It tells you something about his priorities. Luna: Did he ever get anywhere with it? Any foundations laid? Lucas: Not really. The project died on the drawing board. There are a few reasons. First, the practical obstacles: the war was relentless, the plague kept killing potential settlers, and the treasury was drained. Second, the other philosophers he consulted were skeptical. Fronto, his old rhetoric teacher, wrote back a long letter—we have fragments of it—arguing that 'philosophers make terrible citizens because they question every law before obeying it.' Lucas: And then there was Aelius Aristides, the great orator, who wrote a speech called 'To Plato: In Defense of the Four'—basically arguing that Plato's Republic was never meant to be built, only contemplated. He warned Marcus that trying to force ideal forms onto messy reality would end in disappointment. Luna: So even his intellectual heroes pushed back. That must have stung. Lucas: It probably did. Marcus was a man who deeply admired figures like Cato the Younger and the Cynic philosopher Demonax—men who tried to live their philosophy publicly. But he also had a pragmatic streak from years of ruling. So he compromised. Instead of a full philosopher city, he founded a smaller colony for wounded veterans and their families at a place called 'Municipium Aelium Aurelium'—not a utopia, but a gesture. Lucas: Some historians argue that the entire episode is a fiction of the Historia Augusta, but I think there's more to it. Fronto's letters, though fragmentary, clearly reference a 'philosophical settlement' plan, and Cassius Dio, who is usually reliable, mentions it in passing. Plus the idea fits perfectly with Marcus's own writings in the Meditations, where he constantly talks about living in a 'cosmic city' governed by logos. Luna: So it's less about whether the city existed, and more about what the ambition tells us about him. Lucas: Exactly. It shows that Marcus took Plato seriously—not just as a school exercise, but as a blueprint for governance. And it highlights the central tension of his reign: between the philosopher who wanted to build a just society, and the emperor who had to fight barbarians, manage a plague, and deal with a terrible son. Lucas: Now, there's another layer I find fascinating. The city of philosophers wasn't just a Roman idea—it echoes older Greek attempts. In the fourth century BC, Plato himself tried to advise the tyrant Dionysius II of Syracuse on how to create a philosopher-kingdom. It ended badly. And later, the Cynic Diogenes allegedly told Alexander the Great he should build a 'city of wise men' instead of conquering Persia. So Marcus was tapping into a long tradition. Luna: And he knew that tradition well. He'd read all those texts. Lucas: He had. In his correspondence with Fronto, he discusses Plato's Republic at length—Fronto even jokes that Marcus's plan would make him 'a Lycurgus or a Solon,' the great lawgivers of Sparta and Athens. But Marcus wasn't trying to be another Lycurgus; he wanted to create a community governed not by law alone, but by wisdom. Lucas: So why didn't it happen? I think the answer is in the Meditations. Book 2, Chapter 17: 'The art of life is more like the wrestler's than the dancer's.' Marcus knew that life resists perfect choreography. The plague, the wars, the empire's demands—they kept interrupting the dance. And he accepted that, even if he never stopped dreaming. Luna: It's almost poetic. The philosopher king who couldn't build his philosopher city. Lucas: It is. And there's a contemporary echo: in 2008, a group of modern Stoics actually tried to create a 'Stoic community' in rural Portugal called 'The Stoa.' It lasted about six years before internal disagreements and practical challenges ended it. So the dream never really dies. Lucas: If you've been stepping into history with us episode by episode—through Marcus's wars, his plague, his family struggles—you know we try to bring these stories to life without ads or sponsors. For anyone coming with us through these conversations about Mediterranean history, a couple of dollars a month is genuinely what keeps these going. It's at buy me a coffee dot com slash fexingo, if you've gotten something out of them. Luna: Yeah, it really does make a difference. Just a small amount helps cover research time and the costs of hosting. Lucas: So back to the city that never was. There's a curious detail in the Historia Augusta that Marcus allocated funds for the project—five million sesterces, which would have been a huge sum—but after his death, Commodus promptly redirected the money to build a new wing of baths for his own use. That feels symbolic. Luna: Commodus turning a philosopher's dream into a bathhouse. Very on-brand. Lucas: Indeed. But the idea itself survived. A century later, the emperor Julian the Apostate—who was also a philosopher—tried again. He planned a 'city of philosophers' in Galatia, but he died in battle before it could get off the ground. So Marcus's dream haunted later emperors too. Lucas: In the end, maybe the point is that some visions are too big to build, but they still shape how we think about what's possible. Marcus's philosopher city never broke ground, but it's a window into his soul—a man who believed, against all evidence, that reason could transform the world. Luna: And that's maybe the most Stoic thing of all. Lucas: Exactly. Thanks for listening, and we'll see you next time.
