Lucilius is hungry to learn, and Seneca wants that hunger aimed well. In one of his warmest and most personal letters, he remembers being an eager young student, first to arrive and last to leave his teacher Attalus’s classroom, and even going vegetarian for a year. He describes the different kinds of students (some come to hear, few come to learn), shows how the same line of poetry means different things to a scholar and a philosopher, and ends with a challenge to every teacher and student: study for the sake of living well, and make your words into deeds.
From Seneca to Lucilius
The subject you’re asking about is one of those where the only point of knowing is to know. Still, since it does concern us that far, you’re in a hurry. You’re not willing to wait for the books I’m arranging for you right now, which cover the whole field of moral philosophy. I’ll send you the books right away. But first I’ll write and tell you how to manage this eagerness to learn that I see burning in you, so it doesn’t get in its own way.
Take In What You Can Hold
Things shouldn’t be gathered at random, or greedily attacked all at once. You’ll come to know the whole by studying the parts. The load should match your strength; don’t take on more than you can properly handle. Absorb not everything you want, but everything you can hold. Just keep your mind healthy, and then you’ll be able to hold everything you want. For the more the mind takes in, the more it expands.
My Teacher Attalus
I remember this was the advice Attalus gave me in the days when I practically laid siege to his classroom, the first to arrive and the last to leave. Even as he walked up and down, I’d challenge him to various discussions, because he not only made himself available to his students but met them halfway. He used to say: “Teacher and student should share the same purpose: the one’s ambition to help, the other’s to improve.”
Anyone who studies with a philosopher should take away one good thing every day. He should go home each day a sounder person, or on the way to becoming one. And he will, because one of philosophy’s powers is to help not only those who study her but also those who simply spend time with her. Someone who walks in the sun gets tanned even if that isn’t why he went out. Someone who visits a perfume shop and lingers even a little while carries the scent away with him. And someone who follows a philosopher is bound to get some benefit that will help him even if he’s careless. Notice I say “careless,” not “resistant.”
Squatters, Not Students
“What then?” you say. “Don’t we know people who have sat at a philosopher’s feet for years and haven’t picked up the slightest trace of wisdom?” Of course I know them. There are persistent gentlemen who stick with it. I don’t call them students of the wise; I call them squatters.
Some come to hear, not to learn, the way we go to the theater to please our ears with a speech, a song, or a play. As you’ll see, this group makes up a large share of the audience, people who treat the philosopher’s classroom as a lounge for their leisure. They don’t set out to shed any faults there, or to pick up a rule of life to test their characters by. They just want to enjoy the pleasure of listening. Some even arrive with notebooks, not to write down the substance but only the phrases, so they can soon repeat them to others, who’ll get as little benefit from hearing them as they did.
Moved, Then Unmoved
A certain number are stirred by grand phrases and follow every emotion of the speaker with lively changes of face and feeling, like the frenzied priests of Cybele who are roused by the sound of the flute and go mad on cue. But the true listener is carried away by the beauty of the subject, not by the jingle of empty words. When a bold word is spoken in defiance of death, or a defiant jab at Fortune, we feel delighted and want to act on what we’ve heard right away. People are moved by such words and become what they’re urged to be, if only the impression stays in their minds, and if the crowd, which discourages honorable things, doesn’t immediately lie in wait to rob them of this noble impulse. Only a few manage to carry home the frame of mind they were inspired with.
It’s easy to rouse a listener to long for what is right, because Nature has laid the foundations and planted the seeds of virtue in all of us. We’re all born with these common gifts, so when a stimulus is added, the good spirit stirs as if released from chains. Haven’t you noticed how the theater rings with applause whenever someone speaks words whose truth we all recognize and agree with?
The poor lack much; the greedy lack it all.
A greedy man does good to no one; he does
the most harm to himself.
The Power of a Good Line
At verses like these, your stingiest miser applauds and is delighted to hear his own vices attacked. How much truer is this when a philosopher says such things, when he works verses into his wholesome advice to make them sink more deeply into the beginner’s mind! Cleanthes used to say: “Just as our breath makes a louder sound when it passes through the long, narrow tube of a trumpet and bursts out of the flared end, so the tight rules of poetry make our meaning ring out more clearly.” The very same words are heard more carelessly and make less impression when they’re spoken in prose. But when meter is added, and regular rhythm has compressed a noble idea, the same thought comes flying at us with greater force.
We talk a lot about despising money, and we give advice on it in the longest speeches, so people will believe that true riches are in the mind and not in a bank account, and that the person who adapts to slender means and makes himself wealthy on a little is the truly rich one. But our minds are struck far harder when a verse like this is repeated:
He needs but little who desires but little.
or
He has his wish whose wish includes nothing
beyond enough.
When we hear words like these, we’re led to admit the truth.
Strike While the Iron Is Hot
Even people for whom nothing is ever enough marvel and applaud at these words, and swear eternal hatred of money. When you see them in that frame of mind, strike home. Press them, keep at them, and hold them to this duty, dropping all double meanings, syllogisms, hair-splitting, and the other sideshows of useless cleverness. Preach against greed; preach against extravagant living. And when you see you’ve made progress and impressed your listeners’ minds, press harder still. You can’t imagine how much progress a talk like that can produce, when you’re set on healing your listeners and completely devoted to their good. When the mind is young, it’s most easily won over to desire what is honorable and upright. Truth, if she can find a good advocate, will take a strong hold on those who can still be taught, who’ve only been spoiled on the surface.
Wanting to Leave Poor
At any rate, when I used to hear Attalus denouncing vice, error, and the evils of life, I often felt sorry for humanity and thought of Attalus as a noble and majestic being, above our mortal heights. He called himself a king, but I thought he was more than a king, since he had the right to pass judgment on kings.
And truly, when he started praising poverty, and showing what a useless and dangerous burden everything is that goes beyond our needs, I often wanted to leave his classroom a poor man. Whenever he criticized our pleasure-seeking lives and praised purity of life, moderation in eating, and a mind free of unnecessary pleasures, not to mention unlawful ones, I felt the urge to limit my food and drink.
Habits That Stayed
That’s why some of these habits have stayed with me, Lucilius. I had planned my whole life with great resolutions. Later, when I returned to the duties of a citizen, I did keep a few of those good resolutions. That’s why I gave up oysters and mushrooms for good: they aren’t really food, just relishes to bully a full stomach into eating more, which is what gourmets like, and people who stuff themselves beyond what they can digest: down it goes quickly, and up it comes quickly!
That’s also why I’ve avoided perfume all my life, because the best scent for a person is no scent at all. That’s why my stomach doesn’t know wine. That’s why all my life I’ve avoided the sweating baths, and believed that steaming the body thin is both useless and soft. Other resolutions have lapsed, but in such a way that where I stopped abstaining, I’ve kept a limit right next door to abstinence, which may even be a little harder, since it’s easier for the will to cut certain things off completely than to use them in moderation.
My Year Without Meat
Since I’ve started telling you how much stronger my drive toward philosophy was in my youth than it is to continue it in old age, I’m not ashamed to tell you what passion Pythagoras inspired in me. Sotion used to explain to me why Pythagoras gave up eating animals, and why, later, Sextius did too. Each had a different reason, but each reason was noble.
Sextius believed that people had enough to eat without resorting to blood, and that a habit of cruelty is formed whenever killing is practiced for pleasure. He also thought we should cut back the sources of our luxury, and argued that a varied diet was bad for health and unsuited to our bodies.
Pythagoras, on the other hand, held that all living things were related, and that souls passed back and forth, moving from one bodily form to another. If you believe him, no soul ever perishes or stops working, except for a tiny interval while it’s being poured from one body into another. We may wonder when, and after how many changes, a soul returns to a human being after wandering through many dwellings. But meanwhile he made people afraid of guilt and of killing a parent, since they might unknowingly be attacking a parent’s soul, wounding it with knife or teeth, if, as is possible, that related spirit was living for a while in this bit of flesh!
When Sotion had explained this doctrine and added his own proofs, he would say: “You don’t believe that souls are assigned first to one body and then to another, and that what we call death is just a change of address? You don’t believe that the soul of someone who was once human might linger in cattle, or wild animals, or creatures of the sea? You don’t believe that nothing on earth is destroyed, but only changes its home? And that animals too have their cycles of progress and, so to speak, an orbit for their souls, just like the heavenly bodies that revolve in fixed courses? Great men have believed this. So while you keep your own view, hold the whole question open in your mind. If the theory is true, abstaining from meat is purity; if it’s false, it’s thrift. And what harm does it do you to give it some credit? I’m only depriving you of food that lions and vultures live on.”
I was filled with this teaching and began to give up eating animals. By the end of a year the habit was as pleasant as it was easy. I was starting to feel my mind was sharper, though today I wouldn’t swear whether it really was. Do you want to know how I came to give it up? It was like this. My youth coincided with the early part of Tiberius’s reign. Certain foreign religious rites were being introduced at the time, and avoiding certain kinds of meat was taken as a sign of interest in the strange cult. So at the request of my father, who didn’t fear prosecution but hated philosophy, I went back to my old habits. And it wasn’t very hard to persuade me to eat more comfortably.
Eager Beginners, Poor Guides
Attalus used to recommend a pillow that didn’t give way to the body. Even now, as old as I am, I use one so firm it leaves no dent. I’ve told you all this to show you how eager beginners are in their first impulses toward the highest ideals, provided someone does his part in encouraging them and kindling their passion. Mistakes do happen, through the fault of our advisers, who teach us how to argue and not how to live, and through the fault of students, who come to their teachers to develop not their souls but their wits. So the study of wisdom has become the study of words.
Same Line, Different Readers
It makes a great deal of difference what you have in mind when you approach a subject. If someone who studies language examines Virgil and reads the noble line
Time flies away and can’t be brought back,
he doesn’t take it this way: “We have to wake up. Unless we hurry, we’ll be left behind. Time rolls swiftly on and rolls us with it. We’re swept along, ignorant of our fate. We arrange all our plans for the future, and we’re at ease on the edge of a cliff.” Instead, he points out how often Virgil, when speaking of time’s speed, uses the word “flies”:
The best days of our wretched human life
fly first; disease and bitter age come next,
and toil, until harsh death snatches all away.
But someone who reads these lines in the spirit of a philosopher takes the words in their real sense: “Virgil never says ‘time goes,’ but ‘time flies,’ because flying is the fastest kind of movement, and our best days are always the first to be snatched away. So why do we hesitate to get moving, so we can keep pace with the swiftest of all swift things?” The good flies past, and the bad takes its place.
Don’t Save the Dregs for Yourself
Just as the purest wine pours from the top of the jar and the thickest dregs settle at the bottom, so in human life what is best comes first. Shall we let others drink the best and keep the dregs for ourselves? Let this phrase cling to your soul, and let it satisfy you as if it were spoken by an oracle:
The best days of our wretched human life
fly first.
Why “best days”? Because what’s to come is uncertain. Why “best days”? Because in youth we’re able to learn; we can bend minds that are ready and still flexible toward nobler purposes. Because this is the time for work, for keeping our minds busy with study and our bodies with useful effort. What remains is slower and less spirited, nearer the end.
So let’s strive with all our courage, ignoring the distractions along the way. Let’s struggle with a single purpose, so that we don’t realize too late, once we’ve been left behind, how fast this swift-flying time moves, whose course we can’t stop. Let every day, as soon as it comes, be welcomed as the best, and made our own. We must catch what flees.
The Scholar’s Notes
Now the person who reads the lines I just quoted with a scholar’s eye doesn’t reflect that our first days are best because disease is coming and old age weighs on us and hangs over our heads while we’re still thinking about our youth. He thinks instead about how Virgil usually puts disease and old age together, and he’s right about that. For old age is a disease we can’t cure. “Besides,” he says to himself, “notice the word that goes with old age: Virgil calls it bitter”:
disease and bitter age come next.
And elsewhere Virgil says:
There live pale Disease and bitter Age.
There’s no reason to be surprised that each person can draw from the same source what suits his own studies. In the same meadow the cow looks for grass, the dog for a hare, and the stork for a lizard.
Three Readers, One Book
When Cicero’s book On the State is opened by a philologist, a literary scholar, or a student of philosophy, each pursues his inquiry in his own way. The philosopher is amazed that so much could be said in it against justice. The philologist takes up the same book and comments on the text like this: there were two Roman kings, one without a father and one without a mother, since no one can say who Servius’s mother was, and Ancus, Numa’s grandson, has no father on record.
The philologist also notes that the official we call dictator, and read about under that title in our histories, was called in old times the “master of the people.” That name survives today in the augurs’ records, as shown by the fact that the dictator’s second in command was called “master of the horse.” He’ll also note that Romulus died during an eclipse, and that there was a right of appeal to the people even from the kings; this is stated in the priests’ records and is the view of others, including Fenestella.
When the literary scholar unrolls the same book, he writes down in his notebook the forms of words, noting that Cicero uses reapse for re ipsa and, just as often, sepse for se ipse. Then he turns to changes in usage. Cicero says, for example, “since we are called back from the very calx by his interruption.” The line in the racetrack that we call the creta was called the calx by the ancients.
Next he gathers some verses of Ennius, especially those about Africanus:
A man to whom no friend or foe could pay
a fit reward for all his work and deeds.
From this passage the scholar concludes that the word opem once meant not just “help” but “efforts,” since Ennius must mean that neither friend nor foe could pay Scipio a reward worthy of his efforts. Then he congratulates himself on finding the source of Virgil’s words:
above whose head the mighty gate of heaven
thunders,
noting that Ennius stole the idea from Homer, and Virgil from Ennius. For there’s a couplet by Ennius, preserved in this same book of Cicero’s, On the State:
If it is right for a mortal to climb to the regions of heaven,
then the great gate of the sky opens in glory for me.
Turn Words Into Deeds
But so that I too, while working on something else, don’t slip into the philologist’s or the scholar’s department, here’s my advice. All study of philosophy and all reading should be aimed at living the happy life. We shouldn’t hunt for old-fashioned or far-fetched words and odd metaphors and figures of speech. We should look for advice that will help us, for words of courage and spirit that can immediately be turned into action. We should learn them in such a way that words become deeds.
And I believe no one has treated humanity worse than the person who has studied philosophy as if it were a trade to sell, and who lives differently from the way he advises others to live. Those who are guilty of every fault they condemn advertise themselves as examples of useless training.
A Seasick Pilot
A teacher like that can help me no more than a seasick pilot can steer well in a storm. He has to hold the tiller while the waves toss him; he has to wrestle with the sea, so to speak; he has to take in the sails when the storm rages. What good to me is a frightened, vomiting helmsman? And how much greater, do you think, is the storm of life than any storm that tosses a ship! You have to steer, not talk.
All the words these people speak and juggle in front of a listening crowd belong to others. They were said by Plato, by Zeno, by Chrysippus or Posidonius, and by a whole host of Stoics as numerous as they are excellent. I’ll show you how people can prove their words are their own: by doing what they’ve been talking about.
Since I’ve now given you the message I wanted to pass on, I’ll satisfy your craving soon, and save for a new letter a complete answer to your question, so that you don’t come to a thorny subject, one that needs an attentive and careful ear, already tired.
Farewell.
Breaking It Down: A Modern Take on Letter 108
Letter 108 is a love letter to learning, and a warning about learning badly. Seneca remembers his own youthful enthusiasm with affection and a bit of humor, including his year as a vegetarian. He sorts students into types, shows how three people can read the same book and come away with completely different things, and insists that the only reading that matters is reading that changes how we live. For anyone who teaches, studies, or mentors, it’s one of the most useful letters in the collection.
1. Learn at a sustainable pace
“Absorb not everything you want, but everything you can hold.” Cramming and binge-learning feel productive but rarely stick. Steady, digestible learning builds a mind that can hold more over time.
2. The mind grows as you feed it
“The more the mind takes in, the more it expands.” Capacity isn’t fixed. Every real lesson makes room for the next one.
3. Great teachers meet students halfway
Attalus walked among his students and welcomed their challenges. His motto: “Teacher and student should share the same purpose: the one’s ambition to help, the other’s to improve.” That shared purpose is the heart of good mentoring.
4. Take one good thing home every day
“Anyone who studies with a philosopher should take away one good thing every day.” Ask yourself at the end of each day: what did I learn that will make me better? Like walking in the sun, good company rubs off on us even when we’re not trying.
5. Don’t be a squatter
Some people sit through years of teaching without changing at all. Seneca calls them squatters, not students. Coming to hear isn’t the same as coming to learn.
6. Collect substance, not quotes
Some students take notes only on the clever phrases so they can repeat them. It’s a familiar trap: sharing wisdom online without living any of it.
7. The seeds of virtue are in all of us
“Nature has laid the foundations and planted the seeds of virtue in all of us.” That’s why a good line can move even a miser to applause. People are more ready for goodness than we think; they just need encouragement.
8. Inspiration fades unless we act on it
Seneca notes that “only a few manage to carry home the frame of mind they were inspired with.” The crowd quickly talks us out of good impulses. The fix is to act on inspiration before it cools.
9. Teach to heal
Seneca urges teachers to speak plainly against greed and excess, “when you’re set on healing your listeners and completely devoted to their good.” Teaching, like medicine, is about the other person’s well-being, not your performance.
10. Enthusiasm can last a lifetime
Seneca’s youthful resolutions, no oysters, no perfume, no wine, a hard pillow, stayed with him for life. “The best scent for a person is no scent at all.” The habits we form when we’re first inspired can shape our whole lives.
11. Cruelty can become a habit
Sextius gave up meat because “a habit of cruelty is formed whenever killing is practiced for pleasure.” Whatever you eat, the insight is worth pondering: the small cruelties we practice casually can shape our character.
12. A wise wager
Sotion’s argument is clever: “If the theory is true, abstaining from meat is purity; if it’s false, it’s thrift.” When a choice is good under either possibility, it’s an easy one to make.
13. Teach people to live, not just to argue
Mistakes come from advisers “who teach us how to argue and not how to live,” and from students who want sharper wits rather than better souls. “So the study of wisdom has become the study of words.”
14. Our best days come first
“What is best comes first.” Seneca’s reading of Virgil is a call to action: don’t drink the dregs while letting the best of life pour away. “Let every day, as soon as it comes, be welcomed as the best, and made our own.”
15. We find what we’re looking for
“In the same meadow the cow looks for grass, the dog for a hare, and the stork for a lizard.” Three readers can open Cicero and find justice, ancient kings, or word forms. Ask yourself what you’re hunting for when you read.
16. Words should become deeds
“We should learn them in such a way that words become deeds.” This is the thesis of the whole letter, and of this site. Reading Seneca is worthwhile only if it changes how we act.
17. Steer, don’t talk
A teacher who doesn’t live his teaching is like a seasick pilot in a storm. “You have to steer, not talk.” We prove our words are our own “by doing what they’ve been talking about.”
