Letter 83, “On Drunkenness,” opens with one of Seneca’s most enduring pieces of advice: live as if always observed, think as if someone could read your inmost thoughts. From there he describes his own daily routine — the cold plunges, the modest meals, the morning sun — before turning to the letter’s main subject. Some Stoics, including the great Zeno, argued that the wise person could safely get drunk because their virtue would protect them. Seneca disagrees, sharply. Drunkenness, he says, is “voluntary madness” — and far from displaying virtue under pressure, it strips virtue away. Wine doesn’t manufacture vices; it reveals the ones we’ve been hiding.
From Seneca to Lucilius
You’re asking me to give you an account of each day — and the whole day at that. You must think well of me if you believe there’s nothing in my days I’d want to hide. And yet that’s exactly how we should live: as if we lived in plain sight of everyone. That’s how we should think, too — as if someone could read our deepest thoughts. And someone can. What good does it do that something is hidden from other people? Nothing is hidden from God. He is present in our souls; he comes right into the middle of our thoughts — comes in, I mean, in the manner of one who can leave at any moment.
So I’ll do as you ask, and gladly tell you in writing what I’m doing, and in what order. I’ll watch myself continually, and — what’s an extremely useful habit — I’ll review each day. What ruins us most is this: we live by reflex; we never look back at our own lives. We consider what we’re about to do, and even that not always well — but what we’ve done, we don’t think about at all. And yet our plans for the future depend on the past.
A Day in My Life
Today has been complete: no one has stolen any part of it from me. The whole day was divided between rest and reading. A short slice was given to physical exercise — and for that I owe my old age some thanks. The effort isn’t great: as soon as I move, I’m tired. And tiredness is the goal of effort, even for the strong.
You want to know who my training partners are? One is enough for me: my slave Pharius, a likable boy as you know. But I’ll be changing him. I need someone younger now. He claims we’re at the same critical phase of life, because we’re both losing our teeth! But by now I can barely keep up with him when he runs — and very soon I won’t be able to at all. See what daily exercise can do? Two people moving in opposite directions can rapidly create a great distance between them: he goes up as I go down. And you know perfectly well which of these motions happens faster.
I’m wrong, though — our age isn’t going down anymore; it’s collapsing. Still, you want to know how today’s race ended? Something runners rarely manage: we tied.
After this — more exhaustion than exercise — I dipped into cold water. By “cold” I mean the temperature of any not-quite-warm bath. I, the famous cold-water bather, who used to celebrate the new year by plunging into the canal, who at the start of January used to bless the cold pools just as I’d dedicate my mind to plain reading, plain language, and plain meals — I have shifted my campaign first to the Tiber, and then to a warm tub, which on the sunniest days even now warms me up sufficiently. Not much vigor is left in me for bathing.
After that came dry bread and a breakfast without a table — the kind where you don’t even need to wash your hands afterward. Then a very brief nap.
The Habit of Self-Review
You know my habit: I steal a tiny rest from the day’s allotment. I’m content with what’s enough to refresh me, not to put me out. I sometimes know I’ve slept; sometimes I only suspect it.
And now I hear the noise of the Circus games. A sudden roar of unanimous approval beats on my ears. It doesn’t break my thoughts; it doesn’t even interrupt them. I tolerate it all very calmly. So many voices, working together, are no more bothersome to me than the sound of waves or a falling stream — although I remember a certain tribe at whose insistence the course of a river was diverted, just because the inhabitants couldn’t endure its roar.
Why I’m Writing About Zeno
I think I am more easily distracted by what concerns the soul than by sound. Sound only beats the ears. But what concerns the soul disturbs the soul itself.
I don’t want to put any small things in my letter. So I’ll write something to you about a very large matter — and on which there is much disagreement among our school. Zeno, that great man, the founder of our most reverent and most courageous philosophical school, wanted to discourage drunkenness, and he used this syllogism: “No one entrusts a secret to a drunken man. But a secret is entrusted to a good man. Therefore a good man will not get drunk.”
Watch how cleverly this argument is opposed by setting up something parallel — out of many possible refutations let me show you just one: “No one entrusts a secret to a man asleep. But a secret is entrusted to a good man. Therefore a good man does not sleep.” Posidonius defends Zeno’s argument as best he can — but I don’t think it can be defended, even by him. He says the term “drunken man” has two meanings: one, the man who is currently overpowered by wine; the other, the man who is in the habit of getting drunk. Zeno, he says, meant the habitual drunkard, not the man who is momentarily drunk. He says no one would entrust a secret even to a habitual drunkard, because of the danger that he would betray it while drunk.
That’s false. The first syllogism does mean any man who is at the moment drunk — not the habitual drunkard. You’ll certainly admit there’s a great difference between a drunken man and a habitual drunkard. Someone who is drunk for the first time may also not be in the habit of drunkenness. The habitual drunkard, on the other hand, may sometimes not be drunk. So I take the term in the ordinary sense — especially since this is written by a man who professes precision, and who weighs every word with care. Add to this: if Zeno meant it the way Posidonius interprets it, and wanted us to understand “habitual drunkard,” he was setting a verbal trap, an ambush in plain language — and that’s something we should never tolerate when truth is our subject.
But even if Zeno did mean it that way, the conclusion is false. Secrets are entrusted to habitual drunkards too — for example, to messengers and soldiers. And note this: this same argument, valid against drunkenness, also applies against many other things. For example: “No one entrusts a secret to a fool. A secret is entrusted to a good man. Therefore a good man is not a fool.” Or: “No one entrusts a secret to a madman. A secret is entrusted to a good man. Therefore a good man is not a mad.”
The more universally an argument applies, the weaker it is. You arrive at a worn-out conclusion. So I would prefer that Zeno had urged us to renounce drunkenness with great spirit rather than with this kind of logic. Indeed, it’s easier to say what a drunken man cannot do than what he can do. I’ll set forth against the drunkard myself, very shortly — without these syllogisms.
The Wise Man, Wine, and Honest Disagreement
The famous Posidonius even tries to argue, in this same matter, that the wise man’s drinking will not actually be drunkenness. If you take this seriously, you might also say a wise man can swallow poison and not die, or fall asleep and not be asleep, or be cured of hellebore and rid of every disease without losing what’s in his stomach. But really, Posidonius — even if the wise man’s faculties stagger, his tongue trips, and he says foolish things — it’s still drunkenness.
How about this: don’t you think the Stoic Tillius Cimber drank the same kind of wine as Cassius? Cassius drank water; Tillius drained the wine cups. He himself used to say: “How could I possibly bear a master, when I cannot bear my wine?”
I’d like you to picture this for me: there are wise men who, when wine has flooded them, hold their drink — but they’re still drunk. Just as a wise man holding hellebore in his stomach is still being purged by it, even if it doesn’t quite reach the bottom.
“But,” you say, “we don’t say the wise man falls into the same state as a drunken stranger.” Then I’d just like to know what the difference is between a man drunk on wine and a drunken philosopher. Both of them, when wine has gotten the better of them, say and do things they wouldn’t say or do sober.
What Drunkenness Actually Is
Let’s set Zeno aside. Let’s say what we can, in our own person, against this thing — drunkenness — that we should hate. Show me how disgraceful it is to pour more liquor into yourself than your body can hold, and not even know the capacity of your own stomach. Show how often the drunkard does things that make him blush when he’s sober. Establish that drunkenness is nothing but voluntary madness.
Extend the drunkard’s condition to several days. Can you have any doubt about his madness? Even now, it’s no less madness — it just lasts a shorter time. Think of Alexander of Macedon, who in the middle of a banquet ran his closest, most loyal friend Clitus through with a spear. And when Alexander realized what he had done, he wanted to die. Quite right, too.
Drunkenness kindles and exposes every kind of vice. It removes the sense of shame that veils our evil impulses. For more people abstain from doing what is forbidden because they’re ashamed to sin than because their nature is good. When the strength of wine becomes too much and gains control of the mind, every lurking evil comes out of its hiding place.
Drunkenness doesn’t manufacture vices — it brings them out. The lustful man doesn’t even wait for a dark room to indulge himself once he’s drunk; he openly admits to his desires. The greedy man, when drunk, betrays himself: he shouts out the secret of the money he’s hidden. The arrogant man can’t hold his tongue or his hand. The insolent man’s tongue grows sharper. The cruel man’s cruelty grows; the malicious man’s malice grows.
Every vice gets free rein and surfaces. Add to this: the drunkard doesn’t even know who he is. Words come out slurred and broken. The eyes wander. Steps falter. The head swims so that the very roof seems to be moving. The stomach lurches when all the wine in it begins to ferment with great gusts of gas. While it’s happening, you can put up with it. But what about the next day, when you have to think about the wine again?
The Aftermath of a Wasted Night
And just think of the wretched, miserable condition itself — when the wine still surges and breeds calamity, recognized only after the fact. Where is the soul, the soul that meanwhile drowned in pleasures? Is this freedom? No — it’s perfect slavery.
Consider how, in any state — public, private, or anywhere people gather — drunkenness has caused disasters. It betrayed the most savage and warlike tribes to their enemies. It opened up cities defended by long-standing warfare. It crushed nations whose unconquered fierceness in battle had withstood every assault. Drunkenness has ruined as many nations as the sword.
Should we then put down as a virtue what has stripped great commanders of victory and handed them over to their enemies? Should we praise something that has overcome those whom war could not overcome? The honored and great names of our own people have been overthrown by wine. Why even mention it, if Mark Antony, a great man — a man of genius — wasn’t his nature corrupted and brought to the cruel customs of foreign vices by anything other than drunkenness? And no less by love of Cleopatra than of wine? This is what made him an enemy of the state; this is what made him no match even for his rivals.
This is what made him cruel — sending the heads of the greatest men, when he was at dinner, to be displayed; admiring at the most extravagant banquets the faces and the hands of the proscribed; thirsty even while loaded with wine, and — what is more shocking — drunk at the very moment when he poured human blood.
It was intolerable that he was getting drunk while doing these things — but how much more intolerable was it that he was doing these things while drunk! Cruelty almost always accompanies wine, since intoxication corrupts and exposes a healthy mind.
Madness in Other Forms
Just as long-term illness makes people irritable and tiresome — angering them at the slightest contradiction — so continual drunkenness makes the soul savage. For when one is often beside oneself, the habit of madness becomes lasting, and the vices conceived in wine remain even without the wine.
So tell me — why a wise person should not get drunk. Show by deeds, not just words, how foul drunkenness is, how repulsive. Show how easy it is to prove this very obvious fact: that what people call pleasures, once they’re carried past the bounds of moderation, become punishments.
If you try to prove that the wise person is not made drunk by lots of wine, and remains himself even when his footing slips and he raves — feel free to deduce also that he won’t die after taking poison, won’t fall asleep when given a sleeping draught, won’t vomit when given hellebore. But when his footing wavers and his tongue stumbles — on what basis will you say that he is half-drunk and half-sober?
Farewell.
Breaking It Down: A Modern Take on Letter 83
Letter 83 is two letters in one. The first half is Seneca’s daily-life journal — a charming, almost conversational glimpse into his routine. The second half is a fierce critique of drunkenness and the Stoic philosophers who tried to defend it. Here’s what stands out for a modern reader:
1. Live as if Always Observed
Seneca’s opening line is one of the great pieces of practical wisdom in all of philosophy: live as if everyone could see you; think as if someone could read your thoughts. It’s not a call to performative virtue — it’s a reminder that integrity means being the same person in private as you are in public. In our age of edited social-media selves, this is especially urgent.
2. Review Your Day
“Reviewing the day” is a classic Stoic practice, and Seneca puts it perfectly: “What ruins us most is this: we live by reflex; we never look back at our own lives.” A few minutes of honest reflection each evening — what did I do well, what did I do poorly, what will I do differently tomorrow — is one of the simplest and most powerful habits a person can adopt.
3. The Self-Deprecating Old Man
The middle section, where Seneca describes losing a race to his young slave Pharius, is genuinely funny. He’s an old man who can barely keep up, but he reports it cheerfully and with self-deprecating wit. Stoicism isn’t a doctrine of grim seriousness — it’s compatible with humor, lightness, and ordinary human warmth.
4. Don’t Be Bothered by Noise
Seneca writes a letter while a Roman crowd roars at the Circus games next door. He doesn’t flinch. “So many voices, working together, are no more bothersome to me than the sound of waves or a falling stream.” The mind that has done its work isn’t disturbed by the world’s noise. It’s a wonderful image for anyone trying to focus in a distracting age.
5. Beware of Clever Logic in Place of Real Argument
Just as in Letter 82, Seneca turns on his own school. Zeno’s syllogism against drunkenness is clever but useless: it could be twisted to “prove” almost anything (a good man doesn’t sleep, a good man isn’t a fool, etc.). Real moral arguments don’t depend on word tricks. They depend on looking at the thing itself, honestly, and seeing what it does to people.
6. Drunkenness Is Voluntary Madness
This is the line that has echoed for two thousand years: “Drunkenness is nothing but voluntary madness.” When you take a substance that takes away your judgment, your speech, your steadiness, your awareness of who you are — what else is that but choosing temporary insanity? Extend that condition for days, Seneca says, and no one would doubt it’s madness.
7. Wine Reveals, It Doesn’t Create
One of the most psychologically incisive observations in the letter: “Drunkenness doesn’t manufacture vices — it brings them out.” The cruel man becomes more cruel. The lustful, more lustful. The greedy, more greedy. Most people abstain from wrongdoing not because they’re naturally good but because they’re ashamed — and wine strips that shame away. If you want to know who someone really is, watch what comes out when their inhibitions are gone.
8. The Aftermath
Seneca’s portrait of the morning-after is brutal and honest: the swimming head, the unsteady steps, the lurching stomach, and worst of all — the questions about what you said and did the night before. “Where is the soul, the soul that meanwhile drowned in pleasures?” This isn’t moralistic finger-wagging. It’s a clear-eyed look at what we’re actually trading away.
9. Why Public Figures Should Especially Beware
Seneca’s invocation of Mark Antony is devastating. A great man, a man of real genius, undone by wine and infatuation — leading to cruelty, to the public display of severed heads at banquets, to the loss of every advantage he’d built up. The higher you climb, the more devastating your falls. And drunkenness has destroyed more good people than the sword.
10. The Habit Becomes the Character
The most haunting line in the letter: “When one is often beside oneself, the habit of madness becomes lasting, and the vices conceived in wine remain even without the wine.” What you do repeatedly, you become. The drunkard’s cruelty doesn’t disappear when sober — it’s now baked in. Character is built by repetition, for better or worse.
Key Takeaways from Letter 83
- Live as if always observed. Integrity means being the same person in public and in private.
- Review your day. A few minutes of honest reflection each evening transforms how you live.
- Stoicism isn’t grim. Seneca is warm, funny, and self-deprecating about his own old age.
- Train your mind to ignore noise. A well-ordered mind isn’t disturbed by the world’s clamor.
- Beware clever logic that replaces honest argument. Look at the thing itself.
- Drunkenness is voluntary madness. If you wouldn’t accept the state for days, why accept it for hours?
- Wine reveals character; it doesn’t create it. What comes out when shame is gone is who you really are.
- Public figures especially must beware. The higher you climb, the further you fall.
- Habits become character. What you do repeatedly, you become — for better or worse.
