The Exiled Stoic Who Taught Epictetus

Musonius teaching
Be prepared to laugh. Musonius could be severe and hilarious in the same breath—a combination that made him one of antiquity’s most admired teachers.

If Stoicism has a forgotten hero, it is Musonius Rufus.

Today, the names of Seneca, Epictetus, and Marcus Aurelius are familiar to millions. But in antiquity, many regarded Musonius as the greatest Stoic teacher of them all. His lectures attracted students from across the Roman world, foremost among them Epictetus.

Unlike Seneca, Musonius wrote no polished essays. His philosophy was not intended for libraries but for life. He taught in public, argued fearlessly, endured repeated exile, and demonstrated by his example that philosophy is not something merely to discuss, but something to live.

For Musonius, philosophy was not an escape from ordinary life but a preparation for it. It taught people how to eat, work, marry, raise children, endure hardship, and come to terms with death. His school, he liked to say, was not some concert hall, where people came to be amused and entertained, but a hospital, where they came, in trepidation, to be treated.

Yet there was nothing gloomy about him. Though uncompromising in his principles, he possessed a wonderfully dry wit. When a man with a long beard claimed to be a philosopher, Musonius replied that he could see the beard—but not the philosopher.

Beginnings

Gaius Musonius Rufus (c. 25–c. 100 CE) was born in Etruria into a family of Roman equestrians.

As a young man, he went about inquiring into the health of people’s souls, suggesting that his sympathies then lay more with the Cynics than with the Stoics.

He later established himself in Rome as one of the most celebrated Stoic teachers of the age.

When, in 60 CE, the paranoid Nero banished Rubellius Plautus, a Stoic and distant cousin of Nero, Musonius followed his friend to Asia Minor (modern-day Turkey) and only returned to Rome after Plautus’ death in 62.

Second and Third Exiles

When, in 65, Nero learnt of the Pisonian conspiracy, led by the senator Gaius Calpurnius Piso, to have him overthrown, he condemned nineteen people to death, including Seneca. Though not involved in the plot, Musonius was banished to the barren island of Gyaros, the Alcatraz of the Mediterranean.

Exile, however, seemed to weigh lightly upon him, even on Gyaros, and one of his surviving lectures is entitled, Why Exile Is Not an Evil.

Exile, he says, does not deprive us of water, earth, air, or the sun and stars. Nor does it deprive us of human companionship. But by removing us from luxurious living, it can cure our bodies and souls of many ills.

More significantly, exile does not prevent us from caring for our real needs and acquiring virtue. On the contrary, it provides us with more leisure in which to study and do good deeds.

Resourceful people are resourceful wherever they find themselves. Those who lack resourcefulness have vice, and not exile, to blame for their miseries. Ergo, it is vice, and not exile, that we should fear.

Musonius returned to Rome in 68, in the reign of Galba. In 70, in the reign of Vespasian, he accused and obtained the conviction of Egnatius Celer, who, despite calling himself a Stoic, had colluded with Nero in condemning the Stoic Barea Soranius and his daughter Servilia to death.

When, in 71, Vespasian banished all philosophers from Rome, his reputation rode so high that he was tolerated to remain—before being banished all the same into his third and longest exile, this time in Syria.

He returned to Rome in 79, in the reign of Titus, and died around 100 CE.

The Teacher of Philosophy

Musonius exerted an important influence on his two most famous pupils, Epictetus and the polymath Dio Chrysostom (‘Dio the Golden-Mouthed’).

To separate the wheat from the chaff, he would often turn would-be students away, explaining to the young Epictetus that ‘the more one pushes the intelligent person away from the life he was born for, the more he inclines towards it.’

His school, he insisted, was no place for clever performances. People came not to be entertained but to be cured. Because treatment can sometimes be painful, students might expect to suffer a bit. He measured the success of his lectures not by the applause that they received but by the shock and silence that they provoked.

He quoted Homer after Odysseus had related the length of his labours:

Thus he spoke, and they all stayed softly in silence,
And they were held by a magic spell in the shadowy hall.

Epictetus records Musonius saying:

Am I to sit down and tell you clever slogans and sayings so that you praise me as you leave, even though the shoulder is no better than it was, the head still hurts, and the abscess and fistula remain? Do young men leave home for these reasons and leave behind their parents, friends, kinfolk, and property so that they may yell ‘hooray’ when you utter witticisms? Did Socrates do this, or Zeno, or Cleanthes?

Musonius could be severe. By Epictetus’ own account, he once rebuked him for overlooking the omission in a syllogism (formal logical argument). Epictetus sought to excuse himself, saying, ‘It’s not like I burnt down the Capitol’—to which Musonius replied, ‘Idiot, the omission here is the Capitol.’

Nothing worthwhile, he insisted, is acquired without pain. But if we think that the path of virtue is too arduous, let us consider the alternatives and how much more trouble people put up with for the sake of gain or how many ills they suffer for the sake of fame, even though these things are worthless.

Practical Philosophy

Insofar as we know, Musonius did not work on anything for publication. However, two of his students wrote down his sayings and opinions. The Discourses, collected by a certain Lucius, form the basis of the 21 short lectures preserved in Stobaeus. But a second work, by one Pollio, has been lost except for fragments.

All in all, there remain 31 fragments (preserved in Stobaeus, Epictetus, and Aulus Gellius), as well as the 21 lectures, which altogether fit comfortably within 80 or so pages.

Musonius’ lectures are full of practical, everyday advice aimed at instilling virtue and include a lecture on home furnishings and even a lecture on hair. Men, he advised, ought to grow a beard on the grounds that the beard is the mark of manhood, on a par with a cock’s comb or a lion’s mane.

Besides facial hair, Musonius advocated a vegetarian diet (preferably raw and unprepared), plain clothing, and shelter of a kind that offers little more than the protection afforded by a cave.

He once gave a thousand sesterces to a man claiming to be a philosopher. When his friends protested that the fellow was a charlatan, he let him keep the not-inconsiderable sum, explaining that money was exactly what he deserved.

To do philosophy, said Musonius, is to reason correctly, and to reason correctly is to act correctly. The person who does philosophy thereby takes care of his country, family, and friends—in a word, everybody.

The person who does not do philosophy, even if he be a doctor, lawyer, or some such, is thoughtless, and thoughtlessness is very near to insanity.

Even if one rules only oneself, no one is more kingly than a philosopher or more fit to rule, because one cannot rule others unless one first rules oneself.

Musonius was not merely a teacher of Stoicism. He showed what a Stoic looked like.

The Slave Who Inspired an Emperor

Epictetus the slave and Marcus Aurelius the emperor
Epictetus inspired not one but two of Rome’s greatest emperors: Hadrian and Marcus Aurelius

By Dr Neel Burton — Psychiatrist, philosopher, and wine writer; Fellow of Green Templeton College, University of Oxford; author of over twenty books.

A biography of the Roman slave who rose into one of the leading Stoic philosophers, inspired an emperor, and shaped modern psychotherapy.

Stoic philosophy has exerted a profound influence on the history of ideas, inspiring thinkers as diverse as Descartes, Spinoza, Leibniz, Schopenhauer, Adam Smith, and J. S. Mill.

Its influence extends far beyond philosophy. In the field of mental health, Stoicism inspired what has become the most widely practised form of talking treatment, cognitive behavioural therapy (CBT). Aaron Beck (d. 2021), the father of CBT, wrote that ‘the philosophical origins of cognitive therapy can be traced back to the Stoic philosophers.’

Epictetus, together with Seneca, Marcus Aurelius, and Musonius Rufus, is one of our principal sources on Stoicism. But whereas Marcus Aurelius ruled the greatest empire on earth, and Seneca rose into the wealthiest man in that empire, Epictetus began as a slave.

Yet his teachings came to shape an emperor, influence Christian and Islamic thought, inspire the founders of modern psychotherapy, and guide millions in the face of hardship and adversity.

So, how did a mere slave achieve all this?

Life as a Slave

Epictetus (c. 50–c. 135 CE) was born into slavery at Hierapolis, in Asia Minor (modern-day Turkey). His name, in Greek, means something like ‘Acquired One’.

He spent his youth in Rome as a slave to Epaphroditus, a wealthy freedman and secretary to Nero. In 68, Epaphroditus assisted Nero in committing suicide (since Nero could not bring himself to plunge the dagger), with the deluded emperor lamenting, Qualis artifex pereo [‘What an artist dies in me!’].

In those early years, Epictetus, though a slave, discovered philosophy, and even managed to study under the charismatic Stoic Musonius Rufus. Musonius taught that philosophy is not merely something to be discussed but something to be lived—a lesson that Epictetus never forgot.

It is also around this time that he developed a disability, which may have owed to rheumatoid arthritis, although the Christian theologian Origen claims that it was his master who injured him.

One day, according to a famous anecdote, Epaphroditus lost his temper and grabbed Epictetus by the leg. He twisted it so forcefully that Epictetus warned him that it would break. When it snapped, Epictetus did not wince or cry, but calmly said, ‘Did I not tell you that it would break?’

Some time after Nero’s death, by virtue of his education or the dignity which it conferred upon him, Epictetus gained his civil freedom, having already acquired the far greater freedom of the mind.

Now a freedman, he taught philosophy in Rome.

Exile and the School at Nicopolis

When, in 94, Domitian banished all philosophers from the capital, Epictetus settled in Nicopolis, in Epirus, Greece, where he established a school and remained for the rest of his life.

Students travelled from across the Roman Empire to hear him speak. Among them was the young Arrian of Nicomedia, whose notes would preserve Epictetus’ teachings for posterity.

Like Musonius, Epictetus concentrated on ethics, arguing that physics and logic—the other two branches of ancient philosophy—ought to be in the service of practical action:

What do I care if matter is made up of atoms, indivisibles, or fire and earth? Isn’t it enough to know the nature of good and evil, the limits of desire and aversion, and of choice and refusal…?

The purpose of philosophy, he argued, is not to speculate about the stars but to learn how to live, ‘to practise how to remove from one’s life sighs and sorrow, grief and disappointment, and cries of “Alas!” and “Poor me!”’ This is largely a matter of according our will to the world, ‘so that nothing happens contrary to our wishes, and, conversely, nothing fails to happen that we want to happen.’

Hadrian, the future emperor, held Epictetus in the highest regard, and visited him, a former slave, in Nicopolis.

Epictetus’ Lamp

Epictetus did not marry or have children, despite urging these things upon others.

When he rebuked his friend and student Demonax for not marrying, Demonax sarcastically replied, ‘Very well, then, will you give me one of your daughters for a wife?’

However, in his retirement, Epictetus did, out of necessity, adopt the infant child of a friend, and raised him with the help of a woman.

His own needs remained remarkably modest. One day, the iron lamp by which he wrote was stolen. Reasoning that one can lose only what one has, he replaced it with a lamp of clay—which, after his death, was purchased at a great price by an admirer with no sense of irony.

The Discourses and Encheiridion

Epictetus wrote nothing himself. His teachings were recorded as the Discourses (or Diatribai) by his pupil Arrian of Nicomedia, also known for his account of the campaigns of Alexander the Great, written in a very different style.

In a prefatory note, Arrian writes: ‘Whatever I used to hear him say I wrote down, word for word, as best I could…’

He also claims that the Discourses ‘have somehow, without my knowledge or intention, fallen into the public’s hands.’

Such, in any case, is the public story. It is possible that Epictetus wrote the rather polished Discourses himself, with Arrian’s claimed authorship serving as a literary device to create an impression of spontaneity.

Whatever their precise origin, the Discourses remain unique in ancient philosophy. Rather than polished treatises, they preserve the atmosphere of a living classroom, with Epictetus questioning, teasing, rebuking… and constantly bringing philosophy back to the business of living.

Of the original eight books, only four have come down to us, and we also have the more portable Encheiridion, which is a digest of the Discourses—the word encheiridion [Greek, en+ kheir, literally, ‘in hand’]meaning something like ‘to have at hand’, originally with reference to a dagger or knife.

From Emperors to Modern Psychology

According to Origen, by the third century Epictetus’ renown exceeded that of Plato:

Plato is only found in the hands of those reputed to be philologists. By contrast, Epictetus is admired by ordinary people who have the desire to be benefited and who perceive improvement from his writings.

His influence spread far beyond the pagan world. In the ninth century, al-Kindi, the ‘Father of Arab Philosophy’, wrote a Device for Dispelling Sorrows which appears to have been influenced by Stoicism—for instance, in the contention that sorrow arises from thwarted desire, or that it is more a matter of convention than of nature.

In a striking analogy, which also features in the Encheiridion, al-Kindi compares life to a landfall during a much longer sea voyage back to our homeland, and warns us, as Epictetus did, not to get so caught up by the fruits and flowers as to forget about the ship.

Epictetus also left a lasting mark on modern psychology. In the first major work on rational emotive behaviour therapy (REBT), the forerunner of cognitive behavioural therapy (CBT), Albert Ellis (d. 2007) framed his project with a line from the Encheiridion: ‘Men are disturbed not by things, but by the views which they take of them.’

The US fighter pilot James Stockdale (d. 2005) credited Epictetus with helping him survive more than seven years of imprisonment and torture in Vietnam, including four years in solitary confinement in a 3′ by 9′ concrete, windowless cell.

When his A-4 Skyhawk was shot down over North Vietnam, Stockdale remembered thinking to himself as he parachuted towards the jungle: ‘I’m leaving the world of technology and entering the world of Epictetus!’
