5 min readThe Stoic Art of Knowing Yourself: Wisdom From 2,400 Years Ago
When Socrates walked through the Athenian marketplace, he wasn't collecting followers or dispensing tidy maxims. He was, in the words of modern Stoic scholar Donald Robertson, "constantly discussing the nature of wisdom" — treating philosophy not as an academic exercise but as a daily practice of self-examination. The ancient Greeks understood something we've largely forgotten: that the unexamined life isn't just philosophically suspect; it's the root of unnecessary suffering.
What "Know Thyself" Actually Meant
The famous inscription at the Temple of Delphi — gnothi seauton — was one of 147 sayings carved into the stone, most of them just two words long. Plutarch, who served as a priest at Delphi, noted that while these sayings were concise, "books many volumes long have been written about their meaning." Different philosophers interpreted the maxim differently. Xenophon's Socrates believed it meant understanding your strengths and weaknesses, like appraising a horse before buying it. But Seneca and Plutarch offered a deeper reading: because you're entering the presence of the god Apollo, to know yourself is to understand that you are mortal and to come to terms with it.

Show Notes
Donald Robertson is a cognitive behavioral psychotherapist, author of over nine books, and one of the founding voices in the modern Stoicism movement. He has spent over 30 years studying how ancient Greek and Roman philosophy intersects with contemporary psychology, and in this conversation we start where it all begins: the maxim carved into the temple of Apollo at Delphi. Know thyself. We explore what it actually meant, who said it, and why it still matters more than most self-help advice written in the last century.
What We Dive Into:
1. The Stoics drew a sharp line between what actually happens and the value judgments we add on top of it. To say something "is awful" treats our emotional reaction as a fact about the world.
2. Of all the emotions that derail a life, anger gets the least attention in therapy, self-help, and honest self-reflection.
3. In the ancient world, wisdom was not something you consumed or memorized. It was something you practiced daily. Collecting insights without changing your behavior is closer to what the Sophists sold than to what Socrates taught.
Know Thyself, but not by yourself. A guided space to return home to yourself.
