Letter 93, “On the Quality, as Contrasted with the Length, of Life,” is Seneca’s beautiful follow-up to the closing argument of Letter 92. His friend Lucilius is grieving the philosopher Metronax, who died “too soon” — and Seneca uses the moment to deliver one of the clearest statements of the Stoic view of time and life. We should not strive to live long, but to live rightly. An idle eighty-year-old has not lived; he was simply a long time dying. A good man who dies young is not incomplete; his years may be incomplete, but his life is complete. Along the way: jewels measured by weight not width, the gladiator on the last day of the games, the Annals of Tanusius, and a wise man equally brave whether the soul is immortal or simply ends. It is one of the most quietly comforting letters in the collection.
From Seneca to Lucilius
I was reading your letter — the one where you grieve over the death of the philosopher Metronax as if he could have, and indeed should have, lived longer — and I noticed something. That spirit of fairness that runs through everything you write about people and circumstances goes missing the moment you turn to this one subject. And in that, you are exactly like the rest of us. There are many people who deal fairly with their fellow humans; almost no one deals fairly with the gods. Every day we rail at Fate: “Why was A. carried off in the middle of his career? Why was it not B. instead? Why should he prolong an old age that is a burden to himself and everyone around him?”
But tell me — do you really think it is fairer that you should obey Nature, or that Nature should obey you? And what difference does it make how soon you depart from a place you have to depart from sooner or later? We should not strive to live long, but to live rightly. To live long, you need only Fate. To live rightly, you need the soul. A life is truly long if it is a full life — and fullness isn’t reached until the soul has given itself its proper good, which is to say, until it has taken command of itself.
Existing vs Living
What benefit does this older man derive from the eighty years he has spent in idleness? A person like that has not lived; he has merely lingered here. He hasn’t died late in life; he was simply a long time dying. He has lived eighty years, has he? That depends on the date you start counting his death from. Your other friend, on the other hand — the one you say died too soon — left in the prime of his manhood. But he had fulfilled all his duties: as a citizen, as a friend, as a son. He had fallen short in nothing. His years may have been incomplete, but his life was complete. The old man has lived eighty years, has he? No — he has existed for eighty years. Unless by “lived” you mean what we mean when we say a tree is alive.
So let us make sure of this, my dear Lucilius: that our lives, like jewels of great price, are noteworthy not for their width but for their weight. Let us measure them by what they do, not by how long they last. Do you want to know the difference between the hardy man who, scornful of Fortune, has served through every campaign of life and reached its supreme good, and that other person over whose head many years have simply passed? The first goes on existing after his death. The second died before he was dead.
Praise the Life That Was Lived Well
We should praise, then, and number among the blessed, anyone who has invested well even a small allotment of time. Such a person has seen the true light. He has not been one of the common herd. He has not just existed — he has flourished. Sometimes he enjoyed fair skies; sometimes, as is the way of things, the radiance of that mighty star reached him only through clouds. Why do you ask, “How long did he live?” He still lives. In a single bound he has crossed into posterity and entrusted himself to the keeping of memory.
Every Day as the Last
I am not going to refuse a few extra years if they come. But if my life is cut short, I won’t say I lacked anything essential to a happy life. I haven’t planned my life to fit the very last day my greedy hopes have promised me — I have looked at every day as if it were my last. Why ask the date of my birth, or whether I am still listed among the young men? What I have is my own.
Just as a man of small stature can be a complete man, a life of small compass can be a complete life. Age belongs to the external things. How long I exist is not in my control. How long I go on existing in my present way — that is in my control. The only thing you have the right to demand of me is this: that I stop measuring out an inglorious age, as it were in the dark, and devote myself to living instead of being carried along past life.
The Fullest Span Is Wisdom
And what, you ask, is the fullest span of life? It is living until you possess wisdom. Whoever has reached wisdom has reached not the farthest goal but the most important one. Such a person may exult boldly and give thanks to the gods — and to himself, too — and may count himself nature’s creditor for having lived. He has the right: he has paid her back a better life than the one he received. He has set up the pattern of a good man; he has shown what quality and what greatness a good man has. Had another year been added, it would only have been more of the past.
And yet, how long are we meant to keep living? We have had the joy of learning the truth about the universe. We know from what beginnings nature arises; how she orders the course of the heavens; by what successive changes she calls back the year; how she has brought to a close every thing that has ever been, and has established herself as the only end of her own being. We know that the stars move by their own motion, and that nothing but the earth stands still while all the other bodies run on with their uninterrupted swiftness. We know how the moon outstrips the sun; why the slower outpaces the swifter; in what way she receives her light or loses it; what brings on night, what brings back the day. To go and see all of this from closer up — that is where you have to go.
Whether or Not There Is Anything After
“And yet,” says the wise man, “I am not braver about my departure because of this hope — because I judge the path to my own gods to be clear before me. I have earned admission to their presence; I have already been in their company; I have sent my soul to them as they had sent theirs to me. But suppose I am utterly annihilated, and after death nothing mortal remains. I am no less courageous, even if, when I depart, my course leads nowhere.”
“But,” you keep saying, “he hasn’t lived as many years as he could have lived.” There are books with very few lines that are admirable and useful in spite of their size. And there are also the Annals of Tanusius — you know how bulky that book is, and what people say of it. A long life can be the Annals of Tanusius.
The Gladiator Analogy
Do you really regard the gladiator killed on the last day of the games as more fortunate than the one killed in the middle of the festivities? Do you believe anyone is so foolishly greedy for life that he would rather have his throat cut in the dressing-room than in the arena? The interval between us is no longer than that. Death visits each and all; the slayer soon follows the slain. It is an insignificant trifle, after all, that people fuss over with so much concern. And in any case — what does it matter how long you avoid what you cannot escape?
Farewell.
Breaking It Down: A Modern Take on Letter 93
Letter 93 is Seneca’s tender but unflinching response to a friend grieving someone who died young. He doesn’t deny the sorrow. He reframes it. By the time the letter ends, the question “how long did he live?” has been replaced with the better question: “did he live?” — and the difference between those two questions turns out to be everything. This is one of the most useful letters in the whole collection for anyone who has lost someone “too soon” or worried that their own time might be shorter than they planned.
1. We Don’t Deal Fairly With Fate
Seneca opens by gently busting his friend Lucilius for a blind spot we all share. Lucilius is famous for fairness — except when it comes to the gods, where he rails like everyone else. Many people deal fairly with their fellow humans; almost no one deals fairly with the gods. The first move is to notice the unfairness of expecting Nature to bend to our preferences about timing.
2. Live Rightly, Not Long
This is the thesis of the whole letter, and one of the most quoted lines in Seneca: we should not strive to live long, but to live rightly. Length only requires Fate to cooperate. Right living requires the soul. The two have almost nothing to do with each other.
3. The Eighty-Year-Old Who Never Lived
Seneca’s example is brutal and clarifying. An idle eighty-year-old has not lived — he was simply a long time dying. Mere duration produces no life. The metric we keep using — years — is the wrong metric entirely. Calling such a life “lived” is the same as calling a tree alive.
4. Width vs Weight
The image is beautiful. Lives, like jewels of great price, are noteworthy not for their width but for their weight. Measure by what they do, not by how long they last. This is how you tell a brief but full life from a long but empty one.
5. Some Live After Death; Some Die Before Dying
The line of the letter, and one of Seneca’s most chilling formulations: the hardy man goes on existing after his death; the idler died before he was dead. Death isn’t the same event for everyone. For some it is a long-postponed formality; for others it is no more than a punctuation mark in a life that keeps going.
6. Treat Every Day as the Last
The practical move from theory to practice. Seneca isn’t planning his life around the last day his greedy hopes have promised him. He looks at every day as if it were his last. This is the only thing that turns a life of any length into a complete life.
7. Age Is an External
This is huge for anyone steeped in Stoic vocabulary. Age belongs to the same category as wealth, reputation, and weather: things outside our control. How long I exist is not mine to decide. How long I go on existing in my present way is in my control. Make peace with the first; take full responsibility for the second.
8. The Fullest Span Is Wisdom
If you must ask “what is the fullest life?”, here is Seneca’s answer: living until you possess wisdom. Whoever has reached wisdom has reached the most important goal, not the farthest one. Wisdom completes the life. Anything that comes after is just more of the same.
9. Nature’s Creditor
One of the warmest moments in the letter. The wise person is allowed to feel proud, to give thanks, to count himself nature’s creditor — because he has paid back a better life than the one he received. Imagine looking back on your life and saying that.
10. Two Doors, Equal Courage
Seneca makes a striking move in section 10: whether the soul rejoins the gods or simply ends in annihilation, the wise man is equally brave. “I am no less courageous, even if, when I depart, my course leads nowhere.” Stoic equanimity doesn’t depend on settling the metaphysical question.
11. The Annals of Tanusius
The funniest line in the letter. Tanusius wrote a famously bulky and boring history that even Catullus mocked. A long life can be the Annals of Tanusius. Many pages, no value. Better a short book that is admirable and useful than a thick one nobody wants to finish.
12. The Gladiator on the Last Day
The closing analogy is perfect Seneca. Is the gladiator killed on the last day of the games more fortunate than the one killed in the middle? Of course not. The interval between us is no longer than that. Death visits everyone. The slayer soon follows the slain. The whole worry about timing is a trifle we make far too much of.
Key Takeaways from Letter 93
- Live rightly, not long. Length needs Fate; rightness needs the soul.
- Treat Fate fairly. You deal fairly with people — extend the same to Nature.
- Duration is not the measure. Eighty years of idleness is not a life.
- Width vs weight. Measure your life by what it does, not how long it lasts.
- Some die before dying; some live after death. The day of physical death is not always the day life ended — or began ending.
- Live every day as the last. The only way to make a life of any length complete.
- Age is an external. Outside your control. Stop measuring yourself by it.
- The fullest span is wisdom. Wisdom completes a life; more years just repeat it.
- Be nature’s creditor. Pay her back a better life than the one you received.
- Either way, the wise man is equally brave. Whether the soul continues or ends.
- A long life can be the Annals of Tanusius. Bulky doesn’t mean valuable.
- You can’t escape the appointment. Only delay it. That delay is not worth the worry it gets.
“We should not strive to live long, but to live rightly.”
