A friend of Lucilius has walked away from a promising public career, and the people around him are not impressed. They call him lazy, gloomy, a man who sabotaged his own future. In this short, bracing letter, Seneca tells Lucilius to back his friend all the way: success is a restless thing that torments itself, and the quiet life is the place to do the real work of shaping a character that fortune cannot touch. Then the letter turns to the one lesson Seneca thinks every Roman should be trained in, the way other peoples train their children with bow and spear: how to stop fearing death.
From Seneca to Lucilius
Let the Critics Talk
Encourage your friend to brush off, with a stout heart, the people who criticize him for stepping into the shade of a quiet life. He has given up his climb through public office, and although he could have gone further, he chose peace of mind over all of it. Let him show these critics, day after day, how wisely he has looked after his own interests. The people everyone envies will keep marching past him. Some will be shoved out of the ranks; others will simply fall. Prosperity is a turbulent thing — it torments itself. It stirs up the mind in more ways than one, driving people toward different goals: some toward power, others toward luxury. It inflates some people. Others it loosens and drains of all their strength.
“But,” someone will say, “so-and-so handles his success well.” Sure — the way he handles his wine. So don’t let people like that convince you that a man mobbed by crowds is happy. They flock to him the way crowds rush to a pool of water: they muddy it while they drain it.
“But people are calling our friend a lightweight and a slacker.” You know there are people whose words are always crooked, who use every term backwards. They used to call him happy. So what? Was he?
Harsh Wine Ages Well
It doesn’t bother me either that some people find him rough and gloomy. Aristo used to say he preferred a young man with a stern temperament to one who was a fun, easygoing crowd-pleaser. “Wine that tastes harsh and sour when it’s new,” he said, “turns into good wine. But wine that tastes pleasant at the harvest can’t stand up to age.” So let them call him severe and an enemy of his own advancement. It’s exactly that severity that will age well — as long as he keeps loving virtue and keeps soaking himself in the studies that truly form a person. I don’t mean the kind you sprinkle on yourself for appearance’s sake. I mean the kind the mind should be steeped in.
Now is the time to learn. “What? Is there ever a time when a person shouldn’t learn?” Not at all. But while it’s admirable to study at any age, it isn’t admirable to be schooled at any age. An old man learning his ABCs is a shameful and ridiculous sight. The young man must store up; the old man must use.
So you’ll be doing something very good for yourself if you help make this friend of yours as good a man as possible. Those are the favors, they say, that are worth both seeking and giving — the ones that benefit the giver as much as the receiver. And they’re beyond question the best kind.
A Debt Paid in Goodwill
Besides, he isn’t free to change his mind anymore; he’s given his word. And it’s less shameful to default on a creditor than to default on a promising future. To pay off a money debt, a merchant needs a good voyage, and a farmer needs fertile fields and kind weather. But the debt your friend owes can be paid in full by goodwill alone.
Fortune has no jurisdiction over character. Let him order his character so that, in perfect peace, he can bring to completion the spirit within him — a spirit that feels neither loss nor gain, but keeps the same bearing however things turn out. A spirit like that, if it’s piled high with worldly goods, rises above its wealth. And if chance strips away part of that wealth, or all of it, the spirit isn’t diminished in the least.
What Every Person Should Be Trained For
If your friend had been born in Parthia, he’d have started bending a bow as a child. If he’d been born in Germany, he’d have been brandishing a slender spear from the start. If he’d lived in our ancestors’ time, he’d have learned to ride a horse and strike down an enemy hand to hand. These are the skills each people’s way of life recommends to the individual — no, requires of him.
So what should this friend of yours devote himself to? I say: let him learn the one thing that works against every weapon and every kind of enemy — contempt for death. No one doubts that death has something frightening about it. It shakes even our souls, which nature has made to love their own existence. If it didn’t, there would be no need to prepare ourselves and sharpen our courage to face it; we’d move toward it by a kind of willing instinct, just as everyone instinctively moves to preserve their life.
No one trains so that, if the need arises, he can lie down calmly on a bed of roses. He hardens his courage for something else: so that he won’t surrender his pledged loyalty under torture, and so that, if it comes to it, he can stand his watch in the trenches even when wounded, without so much as leaning on his spear — because sleep tends to creep up on anyone who props himself on anything at all.
Nothing Is Lost, Only Changed
There is nothing harmful in death — because for something to be harmful, there has to be someone there for it to harm.
And yet, if you’re gripped by such a craving for a longer life, think about this: none of the things that vanish from our sight and are reabsorbed into the world — the world they came out of and will soon come out of again — is ever destroyed. They simply finish their course; they don’t perish. And death, which we fear and recoil from, interrupts life; it doesn’t steal it. The time will come again when we’re restored to the light of day — and many people would object to that, if they weren’t brought back with no memory of the past.
I’ll show you more carefully later that everything that seems to perish only changes. Since you’re destined to return, you ought to leave with a calm mind. Look at how the great cycle of the universe repeats its course. You’ll see that no star in our sky is ever put out; they all set and rise in turn. Summer has gone, but another year will bring it back. Winter lies low, but its own months will restore it. Night has buried the sun, but day will soon drive night away again. The wandering planets retrace their old paths. One part of the sky is always rising, and another is always sinking.
One more word and I’ll stop. Infants, children, and people who have lost their minds have no fear of death. It would be the height of shame if reason can’t give us the peace that their foolishness has given them.
Farewell.
Breaking It Down: A Modern Take on Letter 36
Letter 36 is really two short letters stitched together. The first half defends a man who has stepped off the career ladder and is getting grief for it; the second half answers the question that naturally follows — if you’re not spending your life climbing, what should you spend it training for? Seneca’s answer is the same one that runs through so many of these letters: learn to stop fearing death, because that one skill protects you against everything else.
1. Stepping back isn’t failing
Lucilius’s friend has chosen a quieter life over a more prestigious one, and his peers read that as weakness. Seneca reads it as good judgment. The people still marching up the ranks aren’t safe — they get pushed out or they fall. “Let him show these critics, day after day, how wisely he has looked after his own interests.” The best rebuttal to people who doubt your choice isn’t an argument; it’s the life you build with it.
2. Success has its own restlessness
We tend to imagine prosperity as a resting place. Seneca sees it as agitation: it drives some people toward power, some toward indulgence, inflates some and softens others. “Prosperity is a turbulent thing — it torments itself.” Anyone who has watched a promotion bring more anxiety than satisfaction knows what he means.
3. Crowds muddy what they drink from
The man everyone swarms around looks enviable, but Seneca’s image is unforgettable: the crowds that rush to a pool “muddy it while they drain it.” Popularity and access aren’t the same as happiness — often they’re the very things that wear a person down.
4. The labels were wrong before, too
People now call the friend a slacker. They used to call him happy. Seneca’s point is that public labels were never reliable in the first place. “They used to call him happy. So what? Was he?” If you didn’t trust the crowd’s praise, you don’t need to trust its criticism either.
5. Stern young people age well
Quoting the Stoic Aristo, Seneca compares character to wine: the harsh vintage matures, the sweet one spoils. A seriousness that looks unappealing now can become depth later — “It’s exactly that severity that will age well.” — so long as it’s paired with real learning, not decorative learning you “sprinkle on yourself for appearance’s sake.”
6. There’s a season for gathering and a season for using
Seneca draws a sharp line between studying (fine at any age) and being taught the basics (embarrassing in old age). “The young man must store up; the old man must use.” The time to build your foundation is now, while there’s still time to stand on it.
7. The best favors help both people
Seneca tells Lucilius that helping his friend become a better man is a gift to himself as well. Mentoring, encouraging, and steadying someone else sharpens your own commitments. Kindnesses that “benefit the giver as much as the receiver” are, in his words, “beyond question the best kind.”
8. Some debts don’t depend on luck
Merchants need fair winds and farmers need good weather to pay what they owe. But the friend’s obligation — to live up to his promise — can be settled entirely from within. “Fortune has no jurisdiction over character.” That’s the heart of the whole letter: the one thing worth building is the one thing chance can’t seize.
9. Every culture trains for something — train for this
Parthians grow up with the bow, Germans with the spear, old Romans on horseback. Seneca asks what his own age should train people for, and answers with the skill that works “against every weapon and every kind of enemy — contempt for death.” Fear of death is the lever behind most other fears; remove it and much of life’s intimidation falls away.
10. Training is for hardship, not comfort
Nobody practices in order to relax on a bed of roses. We train so we can hold firm when it counts — keeping faith under pressure, standing watch while wounded. Seneca’s detail about not even leaning on a spear is telling: “sleep tends to creep up on anyone who props himself on anything at all.” Real steadiness can’t depend on external props.
11. The cycle of nature as consolation
Borrowing an argument made famous by Epicurus — that death can’t harm someone who no longer exists — Seneca then adds a Stoic picture of an endlessly recycling universe: stars set and rise, seasons depart and return. Death “interrupts life; it doesn’t steal it.” Whatever one makes of the metaphysics, the emotional point is clear: nothing in nature’s order is simply thrown away.
12. Reason should do at least as well as innocence
Seneca closes with a jab: small children and people who have lost their reason don’t fear death. “It would be the height of shame if reason can’t give us the peace that their foolishness has given them.” Philosophy, in other words, should get us to calm by understanding, not leave us more anxious than those who don’t understand at all.
