Ryan Holiday and his agent Steve Hanselman on building the Stoic Virtues series

Executive overview

Ryan Holiday's four-book Virtues series — Courage, Discipline, Justice, Wisdom — grew from a single conversation with his literary agent Steve Hanselman, who proposed the concept, supplied the Latin and Greek translations, and sold the series. The books treat the four Stoic cardinal virtues not as abstract ideals but as lived practices: things you do, not things you have.

Wisdom is not a destination — it is ongoing work, and believing you possess it is the surest sign you do not.

The origin of the Daily Stoic and the Virtues series

• Steve Hanselman, who studied at Harvard Divinity School and knows Latin and Greek, approached Holiday with the idea for a page-a-day book modelled on The Daily Drucker.
• Hanselman translated the ancient texts himself, solving the copyright problem that had made Holiday hesitant.
• The four-book series was conceived on a family hike in 2019; the advance funded the purchase of Holiday's bookstore.
• Courage was always placed first in ancient lists of the virtues; the order of the remaining three was contested even among the Stoics.

The interrelatedness of the virtues

• Virtually every example of courage also involves justice — isolating one virtue from the others is a logical, not just philosophical, problem.
• Moral courage almost always requires wisdom: seeing clearly what others cannot because their judgment is clouded by prejudice or convention.
• The Stoics defined practical wisdom (phronesis) as "that which deals with appropriate acts" — a street-level intelligence, not a theoretical ideal.
• Epictetus condensed the whole philosophy to two words: persist and resist — courage (persist) and discipline (resist).
• Sub-virtues reveal the entanglement most clearly: love, for instance, touches all four but probably belongs under justice.

Phronesis: practical wisdom as defined by the Stoics

• Arius Didymus, Stoic advisor to Augustus, listed its components: soundness of judgment, circumspection, shrewdness, sensible aim, ingenuity (mechaneia — fashioning what is needed on the spot).
• Marcus Aurelius added his own reserve clause (hupexairesis): always remain willing to reconsider if the facts change.
• Epictetus: if Chrysippus were a better writer, his students would have less to brag about — the point is application, not erudition.
• Wisdom is discernment — knowing the value and truth of things more clearly than your peers and your moment in time.

Endurance, courage, and discipline

• Physical courage (Kyle Carpenter diving on a grenade) and the endurance that follows (three years of reconstruction surgery) look like the same virtue but are not.
• Day-to-day persistence under suffering crosses from courage into temperance/discipline — sustaining right action when tired, cold, hungry, or in pain.
• Philoponia (love of toil) sits under courage in Arius Didymus's taxonomy, but its practical expression belongs to self-discipline.
• Marcus: do the right thing regardless of the variables; courage provides the moment, discipline provides the duration.

Lincoln, Cleanthes, and the slow-carving mind

• Both Lincoln and Cleanthes were described by their contemporaries as minds that learned slowly but never forgot — Zeno compared Cleanthes to a wax tablet that hardens once carved.
• Lincoln maintained a cabinet of rivals and actively sought correction throughout his life, despite having every reason to stop doing so.
• Marcus Aurelius wrote privately about being wrong and changing his mind even as emperor — a man whose word was law.
• Holiday's own experience: as a writer gains credibility, unsolicited criticism dries up precisely when the stakes are highest and rigorous editing is most needed.

Using historical figures as mirrors

• Plutarch's method: present the full person — virtues and vices — so the reader sees themselves reflected, not a hero to worship or a villain to condemn.
• The Musk chapter in Wisdom Takes Work required steel-manning him first: establishing the genuine genius before tracing how hubris erodes it.
• The Stoics' timeless warning: the moment you believe you are wise, you are in the midst of losing it — "stained purple," Caesarified.
• Epictetus: education is about constantly polishing moral preconceptions as weapons you will need in your own battles, not someone else's.

Wisdom as ongoing practice

• Mussonius Rufus: while we make things in the world (artisans), we are also working on ourselves — our lives are the artifact we leave behind.
• Wisdom, like all virtues, is something you do, not something you have; there are no wise people, only people in the act of doing wisdom.
• The horizon metaphor: you never close the distance, but looking back you can see how far you have actually travelled.
• Zeno: wellbeing is realised step by step — and it is no small thing.
• The deposits you make now (reading, mentors, questions, experience) are what you draw on when you desperately need wisdom later.
