Letter 20On Practising What You Preach

Philosophy is for doing, not talking: Seneca asks Lucilius to prove his words by his deeds, because wisdom is always wanting, and always refusing, the same things. Practise simple living now and then; it shows who your real friends are and gives your words weight.

Ten parts, following the website’s sections. Each has a short explanation and its key line. Open “Read this part in full” for the complete text. Tap a dotted word for its meaning.

  1. Part 1

    Prove your words by your deeds

    Seneca is glad that wants, at last, to be his own master, and hopes to pull him out of the flood of busy life. He asks one thing: let wisdom sink in deep. Measure your progress not by what you say or write, but by a steadier heart and fewer cravings.

    Prove your words by your deeds.

    Verba rebus proba.
    Not talk
    speeches, writings
    A stout heart
    steadier courage
    Fewer wants
    shrinking desire

    If you are in good health and if you think yourself worthy of becoming at last your own master, I am glad. For the credit will be mine, if I can drag you from the floods in which you are being buffeted without hope of emerging. This, however, my dear , I ask and beg of you, on your part, that you let wisdom sink into your soul, and test your progress, not by mere speech or writings, but by and decrease of desire. Prove your words by your deeds.

  2. Part 2

    Philosophy teaches doing, not talking

    Speech-makers chase the applause of a crowd, and clever talkers keep idle young men entertained. Philosophy is different. It asks you to live by your own rules, so that your life matches your words and your inner life matches everything you do. That match, says Seneca, is the highest duty and the surest sign of wisdom.

    Philosophy teaches us to act, not to speak.

    Facere docet philosophia, non dicere.

    Words, deeds and mind: one colour

    words deeds inner life wavering
    Say it, do it, mean it: the three should be one solid piece. When they don’t match, the whole thing wobbles.
    Read this part in full

    Far different is the purpose of those who are speech-making and trying to win the of a throng of hearers, far different that of those who allure the ears of young men and idlers by many-sided or fluent argumentation; philosophy teaches us to act, not to speak; it exacts of every man that he should live according to his own standards, that his life should not be out of harmony with his words, and that, further, his inner life should be and not out of harmony with all his activities.

    This, I say, is the highest duty and the highest proof of wisdom,—that deed and word should be in accord, that a man should be equal to himself under all conditions, and always the same.

  3. Part 3

    The same path, if not the same pace

    Can anyone really live up to this? Very few, Seneca admits, but some do. A wise man won’t always keep the same pace, but he keeps to the same path. So check yourself. Fine clothes but a shabby house? Lavish on yourself but mean to your family? Plain dinners but a grand new building? Pick one rule and shape your whole life by it.

    I do not say that the philosopher can always keep the same pace. But he can always travel the same path.

    Nec hoc dico, sapientem uno semper iturum gradu, sed una via.

    One path, whatever the pace

    short steps long strides same path
    Some days you shuffle, some days you stride. Keep the direction, and the pace can vary.
    Read this part in full

    “But,” you reply, “who can maintain this standard?” Very few, to be sure; but there are some. It is indeed a hard undertaking, and I do not say that the philosopher can always keep the same pace. But he can always travel the same path.

    Observe yourself, then, and see whether your dress and your house are inconsistent, whether you treat yourself lavishly and your family meanly, whether you eat frugal dinners and yet build luxurious houses. You should lay hold, once for all, upon a single norm to live by, and should regulate your whole life according to this norm. Some men restrict themselves at home, but strut with before the public; such is a fault, and it indicates a wavering mind which cannot yet keep its balance.

  4. Part 4

    Why we contradict ourselves

    Where does all this wobbling come from? Nobody settles what he wants. Or if he does, he doesn’t stick to it: he jumps the track, then slides back into the very habits he had sworn off.

    No man resolves upon what he wishes, and, even if he has done so, he does not persist in it, but jumps the track.

    Nemo proponit sibi quid velit, nec si proposuit perseverat in eo, sed transilit.

    We never settle what we want

    sets out jumps the track back to what he gave up
    He picks a road, leaps off it, and circles back to the habits he swore to leave.
    Read this part in full

    And I can tell you, further, whence arise this unsteadiness and disagreement of action and purpose; it is because no man resolves upon what he wishes, and, even if he has done so, he does not persist in it, but jumps the track; not only does he change, but he returns and slips back to the conduct which he has abandoned and .

  5. Part 5

    Wisdom: always wanting the same things

    Skipping the old textbook definitions, Seneca gives his own: wisdom is always wanting the same things and always refusing the same things. No need to add that what you want must be right, because only what is right keeps pleasing you for good. Most people know what they want only in the moment, so their lives drift like a game. Keep going as you’ve begun.

    What is wisdom? Always desiring the same things, and always refusing the same things.

    Quid est sapientia? Semper idem velle atque idem nolle.

    Want and refuse the same things, always

    always want always refuse
    Like a compass needle: one end always points to what you want, the other to what you refuse, whichever way the day turns.
    Read this part in full

    Therefore, to omit the ancient definitions of wisdom and to include the whole manner of human life, I can be satisfied with the following: “What is wisdom? Always desiring the same things, and always refusing the same things.” You may be excused from adding the little ,—that what you wish, should be right; since no man can always be satisfied with the same thing, unless it is right.

    For this reason men do not know what they wish, except at the actual moment of wishing; no man ever decided once and for all to desire or to refuse. Judgment varies from day to day, and changes to the opposite, making many a man pass his life in a kind of game. Press on, therefore, as you have begun; perhaps you will be led to perfection, or to a point which you alone understand is still short of perfection.

  6. Part 6

    What poverty reveals

    Lucilius worries about his big if he gives up his income. Seneca says the crowd will feed itself once he stops feeding it. Better still, poverty sorts your friends: the true ones stay, and those who only wanted something from you leave. Imagine a day when no one lies to flatter you.

    Poverty will keep for you your true and tried friends.

    Illa veros certosque amicos retinebit.

    Poverty shows who loves you

    true friends stay the rest leave
    When there’s nothing left to hand out, only the people who wanted you stay.
    Read this part in full

    “But what,” you say, “will become of my without a household income?” If you stop supporting that crowd, it will support itself; or perhaps you will learn by the of poverty what you cannot learn by your own bounty. Poverty will keep for you your true and tried friends; you will be rid of the men who were not seeking you for yourself, but for something which you have.

    Is it not true, however, that you should love poverty, if only for this single reason,—that it will show you those by whom you are loved? O when will that time come, when no one shall tell lies to compliment you!

  7. Part 7

    Be content with yourself

    So aim every thought and effort at one goal: being content with yourself and with the good things that come from within. Leave every other wish to God. Bring yourself down to a simple life that no one can throw you out of. Seneca adds that this letter’s usual small gift will help with exactly that.

    Bring yourself down to humble conditions, from which you cannot be ejected.

    Redige te ad parva ex quibus cadere non possis.
    Read this part in full

    Accordingly, let your thoughts, your efforts, your desires, help to make you content with your own self and with the goods that spring from yourself; and commit all your other prayers to God’s keeping! What happiness could come closer home to you? Bring yourself down to humble conditions, from which you cannot be ejected; and in order that you may do so with greater , the contained in this letter shall refer to that subject; I shall bestow it upon you forthwith.

  8. Part 8

    Words backed by a cot and rags

    The gift comes, once again, from : your words carry more weight if you sleep on a and wear rags, because then you prove them as well as say them. Seneca feels this with his friend , who sleeps without even a cloak or a rug. He doesn’t just teach the truth; he is a witness to it.

    He is not only a teacher of the truth, but a witness to the truth.

    Non praeceptor veri sed testis est.

    Your words weigh more from a cot

    proved, not just said a cot and rags
    A teacher who lives what he teaches doesn’t only say his words; he shows they’re true.
    Read this part in full

    Although you may look , will once again be glad to : “Believe me, your words will be more imposing if you sleep on a and wear rags. For in that case you will not be merely saying them; you will be demonstrating their truth.”

    I, at any rate, listen in a different spirit to the utterances of our friend , after I have seen him reclining without even a cloak to cover him, and, more than this, without rugs to lie upon. He is not only a teacher of the truth, but a witness to the truth.

  9. Part 9

    Rich amid riches, or poor amid them?

    Can’t a man despise wealth while it sits in his pocket? Of course. It takes a great soul to be surrounded by riches, smile, and barely feel they are his. An objector asks how such a man would cope with sudden poverty; Seneca turns it round: would Epicurus’s poor man cope with sudden wealth? Either way, judge the mind, and check that the simple life is chosen, not forced.

    He is truly great who is poor amidst riches.

    Magnus ille qui in divitiis pauper est.

    Poor in the midst of riches

    not spoiled by them
    He can live among heaps of money without being owned by it. What counts is the mind, not the money.
    Read this part in full

    “May not a man, however, despise wealth when it lies in his very pocket?” Of course; he also is , who sees riches heaped up round him and, after wondering long and deeply because they have come into his possession, smiles, and hears rather than feels that they are his. It means much not to be spoiled by intimacy with riches; and he is truly great who is poor amidst riches.

    “Yes, but I do not know,” you say, “how the man you speak of will endure poverty, if he falls into it suddenly.” Nor do I, Epicurus, know whether the poor man you speak of will despise riches, should he suddenly fall into them; accordingly, in the case of both, it is the mind that must be appraised, and we must investigate whether your man is pleased with his poverty, and whether my man is displeased with his riches. Otherwise, the cot-bed and the rags are slight proof of his good intentions, if it has not been made clear that the person concerned endures these trials not from necessity but from preference.

  10. Part 10

    Rehearse it because it’s easy, not because it’s nobler

    Don’t rush into poverty as if it were the better life. Practise for it, because it is easy to bear, and after long rehearsal even pleasant, since it frees you from worry. So set aside a few days of pretend poverty to prepare for the real thing. We are soaked in luxury, and the soul needs waking up: nature asks for very little. No one is born rich.

    No man is born rich. Every man, when he first sees light, is commanded to be content with milk and rags.

    Nemo nascitur dives.

    No one is born rich

    rags milk all we start with
    We arrive with milk and a few rags. Later, whole kingdoms feel too small.
    Read this part in full

    It is the mark, however, of a noble spirit not to into such things on the ground that they are better, but to practise for them on the ground that they are thus easy to endure. And they are easy to endure, Lucilius; when, however, you come to them after long rehearsal, they are even pleasant; for they contain a sense of freedom from care,—and without this nothing is pleasant.

    I hold it essential, therefore, to do as I have told you in a letter that great men have often done: to reserve a few days in which we may prepare ourselves for real poverty by means of . There is all the more reason for doing this, because we have been steeped in luxury and regard all duties as hard and . Rather let the soul be roused from its sleep and be prodded, and let it be reminded that nature has prescribed very little for us.

    No man is born rich. Every man, when he first sees light, is commanded to be content with milk and rags. Such is our beginning, and yet for us! Farewell.

The modern take

The website breaks Letter 20 into 12 lessons for today. I’ve grouped them into four themes; each lesson is summarised in plain words.

Live what you say

Lessons 1–3
  1. 1

    Prove your words with your deeds

    Judge your progress by courage and fewer cravings, not by how well you talk or write.

  2. 2

    Philosophy is for doing, not talking

    An idea only counts once it shows up in the way you actually live.

  3. 3

    Be all one colour

    Be the same person in public, at home and in your own head, with no hidden compartments.

One road, any pace

Lessons 4–5
  1. 4

    The same path, if not the same pace

    You will speed up and slow down. What matters is that you keep heading the same way.

  2. 5

    Find the contradictions in your own life

    Look where your spending, your image and your values pull apart. That’s where the work is.

A settled will

Lessons 6–8
  1. 6

    Why we keep contradicting ourselves

    The root problem is a will that never settles: we keep swapping our goals, not just missing them.

  2. 7

    Wisdom is wanting the same things, always

    A wise mind holds to a steady set of good values instead of the mood of the day.

  3. 8

    Most people live by chance

    Without settled aims, passing feelings push you around and your life turns random.

The test of poverty

Lessons 9–12
  1. 9

    Poverty shows who loves you

    Once you have less to give, the friends who only wanted your things drift off, and the real ones show.

  2. 10

    A teacher and a witness to the truth

    We believe teachers whose own lives already prove what they say.

  3. 11

    Rich amid riches, or poor amid them

    The goal is a mind that wealth can’t spoil, not necessarily giving the wealth away.

  4. 12

    No one is born rich

    We start out needing almost nothing. Remembering that puts a brake on endless wanting.

stoutness of heart
Courage; a firm, steady spirit.
approbation
Approval; here, the applause of an audience.
of one hue

Solemnly renounced; sworn off.
proviso
A condition or exception added to a statement.
household
A rich Roman household was a crowd of slaves, freedmen and hangers-on, all fed by the master.
bounty

alacrity
Eagerness; brisk readiness.
contribution
Seneca’s running joke: his early letters each end with a small “payment” for Lucilius, usually a saying of Epicurus.
Epicurus
Greek philosopher (341–270 BC), founder of a rival school. Seneca borrows his sayings anyway.

kingdoms are all too small
An echo of the saying about Alexander the Great, for whom even a whole kingdom was not enough.
A few fun factsOptional, six short ones
  • Seneca’s definition of wisdom borrows a line the historian Sallust used for friendship: wanting and not wanting the same things (idem velle atque idem nolle) is what makes a friendship firm.
  • The earlier letter about practising poverty is Letter 18, set during the Saturnalia festival: a few days of the plainest food and roughest clothes.
  • The man recommending the cot and rags was one of the richest men in Rome, a point his enemies made at the time.
  • Seneca writes elsewhere that the emperor Caligula once offered Demetrius 200,000 sesterces. Demetrius laughed and turned it down.
  • “Kingdoms are all too small” echoes Philip of Macedon telling young Alexander to find a kingdom of his own, since Macedonia was too small for him.
  • The Latin word for the cot, grabattus, is the bed in “take up thy bed, and walk” in the Latin Gospels.
