Zeno of Citium was a merchant from Cyprus who lost everything in a shipwreck. He ended up in Athens, wandered into a bookshop, and became fascinated by accounts of Socrates. He began studying under the Cynics and other philosophers, and eventually started teaching his own ideas at the Stoa Poikile — a public covered walkway decorated with painted murals depicting famous battles. It was essentially an open-air classroom, and anyone could listen. That accessibility was part of the ethos from the beginning: this was philosophy for living, not just for academics.

​

Zeno's core teaching was that virtue — meaning wisdom, courage, justice, and self-discipline — is the only true good, and that external things like wealth, reputation, and even health are "preferred" but ultimately not necessary for a good life. What matters is how you respond to what happens to you, not what happens to you. That idea became the spine of everything that followed.

​

After Zeno, the school passed through several leaders, but the three names that dominate your document — Epictetus, Seneca, and Marcus Aurelius — all came centuries later during the Roman period, which is often called the "Late Stoa." What's remarkable about those three is how different their circumstances were. Epictetus was a former slave. Seneca was one of the wealthiest men in Rome and an advisor to Emperor Nero. Marcus Aurelius was the Emperor himself. Yet all three arrived at essentially the same conclusions about discipline, self-examination, present-moment awareness, and emotional mastery — which is a powerful testament to the universality of the ideas.

​

A few threads that connect directly to your Gentlemen of Greatness framework:

​

The dichotomy of control — Epictetus taught that the only things truly in your power are your own judgments, desires, and actions. Everything else is external. Your document echoes this constantly: "Rule your mind or it will rule you," "Train your mind to be stronger than your feelings," "Know that you are in charge of your own happiness."

​

The daily review — Seneca practiced a nightly review of his day, examining what he did well and where he fell short. Your document includes this almost verbatim in both the Motivation section and the Daily Meditations.

​

Memento mori — the reminder of death. Marcus Aurelius wrote extensively about mortality not to be morbid but to sharpen focus and urgency. His quote in your document — "Death smiles at us all, but all a man can do is smile back" — is the essence of this. Life is finite, so waste nothing.

​

Amor fati — love of fate. The idea that you don't just endure what happens to you, you embrace it as necessary for your growth. Seneca's passage in your document about the fighter who has "seen his own blood" and "rises again with greater defiance" is a perfect expression of this.

​

So when we draw on these thinkers, we are drawing on a tradition that was forged by a shipwrecked merchant, refined by a slave, practiced by a statesman, and perfected by an emperor — all anchored in the belief that a man's character is the only thing fully within his control. That lineage is worth knowing, because it gives our Masterclass a foundation that goes back over two thousand years.
