Stoic quotes about time

The short answer

Seneca’s point about time is not that life is short but that we waste it. Marcus Aurelius keeps returning to the present as the only time we have, and Epictetus asks why the effort planned for tomorrow can’t start today. Here are their words, verified and cited, and the time quote they never wrote.

Seneca: we don’t lack time, we waste it

Seneca made the classic Stoic argument about time in a short essay, On the Shortness of Life, addressed to Paulinus, the official who ran Rome’s grain supply. The core of its case fits in two passages.

Seneca on the length of lifeVerbatim

We do not have a very short time assigned to us, but we lose a great deal of it: life is long enough to carry out the most important projects: we have an ample portion, if we do but arrange the whole of it aright: but when it all runs to waste through luxury and carelessness, when it is not devoted to any good purpose, then at the last we are forced to feel that it is all over, although we never noticed how it glided away. Thus it is: we do not receive a short life, but we make it a short one, and we are not poor in days, but wasteful of them.

SenecaOn the Shortness of Life 1Translated by Aubrey Stewart (1889)

Seneca starts from the complaint everyone makes, that life is too short, and turns it down. The amount was never the trouble; the handling is. His last sentence says it plainly: “we are not poor in days, but wasteful of them” (On the Shortness of Life 1). Notice the verb in Stewart’s English: the time “glided away.” Seneca isn’t describing a dramatic loss. He means the evening that disappeared into a phone, or the year that went to a job you meant to leave after six months. The waste is quiet, which is why it is so easy to keep doing.

Seneca on putting life offVerbatim

… postponement is the greatest waste of life: it wrings day after day from us, and takes away the present by promising something hereafter: there is no such obstacle to true living as waiting, which loses to-day while it is depending on the morrow. You dispose of that which is in the hand of Fortune, and you let go that which is in your own. Whither are you looking, whither are you stretching forward? everything future is uncertain: live now straightway.

SenecaOn the Shortness of Life 9Translated by Aubrey Stewart (1889)

The second passage names the habit that does most of the wasting. Postponement “takes away the present by promising something hereafter” (On the Shortness of Life 9). The promise always sounds reasonable: after this deadline, once the kids are older, when things calm down at work. Seneca’s objection comes in the next sentence: you dispose of what is “in the hand of Fortune” and let go of what is in your own. His closing words, “live now straightway,” are about today, not about a better-organized version of next year.

He makes the same case in the first of his Letters to Lucilius: in our paraphrase, nothing is truly ours except time, so hold on to every hour (Letter 1).

Marcus Aurelius on time and the present

Marcus Aurelius wrote the Meditations in Greek as private notes to himself, and time is one of the subjects he returns to most. His concern is mostly scale: how fast things pass, how small one life is against the whole of time, and how little of time is ever in our hands.

Time is like a river

Meditations 4.43Verbatim

Time is like a river made up of the events which happen, and a violent stream; for as soon as a thing has been seen, it is carried away, and another comes in its place, and this will be carried away too.

Marcus AureliusMeditations 4.43Translated by George Long (1862)

That is the whole entry. In Long’s wording time is like a river, and the river is “made up of the events which happen” (Meditations 4.43). So it isn’t an empty clock ticking in the background. It is the stream of things that happen to you, this morning’s meeting and tonight’s argument about the dishes included. Each one is seen, carried off and replaced. Some modern translations drop the like and say flatly that time is a river, which is the version people search for. Rivers as a picture of change go back to Heraclitus, the early Greek philosopher whose physics the Stoics took as the inspiration for their own (Stanford Encyclopedia of Philosophy (opens in a new tab)).

Meditations 5.23Verbatim

Often think of the rapidity with which things pass by and disappear, both the things which are and the things which are produced. For substance is like a river in a continual flow, and the activities of things are in constant change, and the causes work in infinite varieties; and there is hardly anything which stands still. And consider this which is near to thee, this boundless abyss of the past and of the future in which all things disappear. How then is he not a fool who is puffed up with such things or plagued about them and makes himself miserable? for they vex him only for a time, and a short time.

Marcus AureliusMeditations 5.23Translated by George Long (1862)

Here the river carries everything material, and Marcus draws the practical conclusion. Whatever you are “puffed up with” or “plagued about” is in the current with everything else, and it can vex you “only for a time, and a short time” (Meditations 5.23). The promotion you are proud of and the remark you can’t stop replaying are both already moving downstream. That is no reason to stop caring about your work. It is a reason not to let either one run your week.

A point in time

Meditations 2.17Verbatim

Of human life the time is a point, and the substance is in a flux, … And, to say all in a word, everything which belongs to the body is a stream, and what belongs to the soul is a dream and vapor, and life is a warfare and a stranger's sojourn, and after fame is oblivion. What then is that which is able to conduct a man? One thing, and only one, philosophy. … accepting all that happens, and all that is allotted, as coming from thence, wherever it is, from whence he himself came; and, finally, waiting for death with a cheerful mind, as being nothing else than a dissolution of the elements of which every living being is compounded.

Marcus AureliusMeditations 2.17Translated by George Long (1862)

“Of human life the time is a point” (Meditations 2.17). Marcus opens with the smallest measure he can find, and the list that follows is bleak on purpose: the body a stream, the soul a dream and vapor, fame followed by oblivion. Then the turn. What can steer a life that brief? “One thing, and only one, philosophy,” and the lines after it are practical: do nothing without a purpose, accept what is allotted. The bleak list clears the ground. Once you stop expecting time or reputation to last, the question left is how to spend the stretch you have.

Meditations 4.50Verbatim

It is a vulgar, but still a useful help towards contempt of death, to pass in review those who have tenaciously stuck to life. … Altogether the interval is small [between birth and death]; … For look to the immensity of time behind thee, and to the time which is before thee, another boundless space. In this infinity then what is the difference between him who lives three days and him who lives three generations?

Marcus AureliusMeditations 4.50Translated by George Long (1862)

Marcus admits the first exercise here is “vulgar,” meaning common rather than refined: think of people who clung hard to life, and notice that they are dead too. Then he widens the frame. Against the boundless time before and after, what separates “him who lives three days and him who lives three generations” (Meditations 4.50)? In a sentence this excerpt leaves out, he goes further and tells himself not to count life as a thing of value at all. You don’t have to follow him that far to use the arithmetic. If length can’t be what makes a life good, then what you do with the days matters more than how many there are, which is Seneca’s point reached from the other side.

Only the present is yours

Meditations 6.32Verbatim

I consist of a little body and a soul. Now to this little body all things are indifferent, for it is not able to perceive differences. But to the understanding those things only are indifferent which are not the works of its own activity. But whatever things are the works of its own activity, all these are in its power. And of these however only those which are done with reference to the present; for as to the future and the past activities of the mind, even these are for the present indifferent.

Marcus AureliusMeditations 6.32Translated by George Long (1862)

This is Marcus at his most technical, and the last sentence is the one to keep. He narrows the field twice. Of everything about him, only the mind’s own acts are in its power; and of those, only the ones “done with reference to the present” (Meditations 6.32). Last year’s decision to take the job is now a settled fact, no more yours to change than the date on the contract. What is yours is the judgment you make about it this afternoon, and what you do next.

Meditations 7.29Verbatim

Wipe out the imagination. Stop the pulling of the strings. Confine thyself to the present.

Marcus AureliusMeditations 7.29Translated by George Long (1862)

Three short orders that belong together. Marcus explains the first himself in 8.29: you wipe out an imagination by reminding yourself that it is in your power to keep agitation out of your mind and to see each thing for what it is. The strings are an image he uses several times for desires that jerk a person about like a puppet (2.2, 3.16, 6.16). The third order says where attention goes once the first two are done: “Confine thyself to the present” (Meditations 7.29). It draws a line around what is actually happening and keeps your attention inside it, the same move as “circumscribest” in 8.36 below.

Meditations 8.36Verbatim

Do not disturb thyself by thinking of the whole of thy life. Let not thy thoughts at once embrace all the various troubles which thou mayest expect to befall thee: but on every occasion ask thyself, What is there in this which is intolerable and past bearing? for thou wilt be ashamed to confess. In the next place remember that neither the future nor the past pains thee, but only the present. But this is reduced to a very little, if thou only circumscribest it, and chidest thy mind if it is unable to hold out against even this.

Marcus AureliusMeditations 8.36Translated by George Long (1862)

Here the present is a relief rather than a demand. Marcus tells himself not to take on “the whole of thy life” at once (Meditations 8.36). Neither past nor future can hurt him, only the present, and the present shrinks to very little once its edges are marked. Think of the first month of a new job, or the long middle of a degree. Seen whole, it looks impossible. Seen as this morning’s work, it usually isn’t. For 8.36 as a way to handle worry, see Stoicism and worry.

Epictetus: why not today?

Epictetus says less than Marcus about time in the large and more about the day in front of you. His short discourse “On Attention” is about what it costs to let your attention lapse and promise to pick it up later.

Epictetus on attentionVerbatim

When you have remitted your attention for a short time, do not imagine this, that you will recover it when you choose; but let this thought be present to you, that in consequence of the fault committed today your affairs must be in a worse condition for all that follows. … is it possible to be free from faults (if you do all this)? It is not possible; but this is possible, to direct your efforts incessantly to being faultless. For we must be content if by never remitting this attention we shall escape at least a few errors. … If it is good to use attention tomorrow, how much better is it to do so today?

EpictetusDiscourses 4.12Translated by George Long (1877)

The opening warning is the sharpest part. A lapse of attention looks like a pause you can end at will, and Epictetus says it isn’t: you won’t simply “recover it when you choose” (Discourses 4.12), and your affairs are worse for everything that follows. The middle of the excerpt sets a bar you can reach. Perfection is off the table; steady aim at it is not, and escaping “at least a few errors” counts. The last line is the one for a Sunday night: “how much better is it to do so today?” The modern case is the phone at dinner, or the plan to be more patient with your kids once the busy season ends, a season with a way of renewing itself.

For Epictetus on putting off, day after day, the point at which you start living as someone making progress (Enchiridion 51), see Stoicism and procrastination.

Time quotes to check before you share them

“Time is what we want most, but what we use worst”

This line is widely shared as Marcus Aurelius. It is not in the Meditations. It comes from William Penn, the English Quaker who founded Pennsylvania, writing some fifteen centuries after Marcus in the preface to his book of maxims Some Fruits of Solitude. Penn’s sentence is a little longer than the meme, “Time is what we want most, but what, alas! we use worst,” and it goes on to say that God will strictly reckon with us for how we used it. In Penn’s English, want could mean lack as well as desire.

It is easy to see why the line drifted to the Stoics. It says in one sentence what Seneca argues in On the Shortness of Life 1. If you want the Stoic version, quote Seneca’s, above.

Genuine, but in someone else’s words

Several real Stoic lines about time circulate in modern translations, which is why they don’t match the wording on this page:

  • Not a short time, but much of it wasted. Genuine Seneca, On the Shortness of Life 1, in a modern translation. Stewart’s wording of the same sentence opens the passage at the top of this page.
  • Life is long if you know how to use it. Genuine Seneca, chapter 2, and close to his Latin. Stewart’s translation adds one word, saying life is long enough; our guide to On the Shortness of Life shows the passage.
  • Time as a river. Genuine Marcus, Meditations 4.43, shown above in Long’s wording.
  • Time as the only thing that is truly ours. Genuine Seneca, Letters to Lucilius 1. The usual English translations of the Letters are still under copyright in many countries, so we describe the letter above rather than quote it.

Spend this week on purpose

Seneca’s own exercise, an audit of where a life’s years actually went, is in chapter 3 of On the Shortness of Life, and our guide to the essay turns it and two other ideas from Seneca into practices for an ordinary week. The passages from Marcus and Epictetus suggest three more.

  • Pick one place to pay attention. Epictetus describes attention as a habit, built or lost a day at a time. Choose one moment that recurs this week, such as dinner, the first ten minutes at your desk or the drive home, and give it your whole attention each day, starting today rather than Monday.
  • See the week at its real size. Marcus sets one life against all of time in 2.17 and 4.50. The memento mori calendar draws a life as a grid of weeks, so this week shows up as what it is, one small square among a few thousand.
  • Close each day. The Evening Examination is a short nightly review: what went well, what to do better and what outside your control disturbed you. Today’s teaching opens the next morning with a passage and a practice.

Questions

Did Marcus Aurelius say 'Time is what we want most, but what we use worst'?
No. The line is William Penn’s, from the preface to his book of maxims Some Fruits of Solitude, where it reads ‘Time is what we want most, but what, alas! we use worst.’ Penn was the English Quaker who founded Pennsylvania, and he wrote some fifteen centuries after Marcus. The thought is close to Seneca’s in On the Shortness of Life 1, which may be part of why it gets credited to the Stoics.
What does 'time is like a river' mean in Marcus Aurelius?
In Meditations 4.43 Marcus says time is like a river made up of the events that happen: as soon as a thing has been seen it is carried away, and another takes its place. He draws the lesson himself when the image returns in 5.23: since everything is carried off, it is foolish to be puffed up by things or plagued about them, because they can trouble you only for a short time. Some modern translations drop Long’s ‘like’ and say simply that time is a river.
What is the Stoic view of the present moment?
That it is the one stretch of time in which you can actually do anything. Marcus says that of the mind’s own activities, only those concerned with the present are in its power (Meditations 6.32), and he tells himself to confine himself to the present (7.29). The Stoics still planned and reflected, but the planning and the reflecting both happen now, and only what you do now is up to you.
What did Marcus Aurelius say about time?
Several things, scattered through the Meditations. Time is like a river of events (4.43); a human life is a point (2.17); against the boundless time before and after us, three days and three generations come to much the same (4.50); and of the mind’s own acts, only those that concern the present are in its power (6.32). He also says that each of us loses only the present, because it is the only life we have (2.14), a passage shown on Stoic quotes about death.
What is the best-known Stoic quote about wasting time?
Seneca’s, from On the Shortness of Life 1. In Aubrey Stewart’s 1889 translation it ends: ‘we are not poor in days, but wasteful of them.’ The famous modern line about not having a short time to live but wasting much of it is a different translation of the same chapter. Seneca’s whole argument is in our guide to On the Shortness of Life.
