The Dichotomy of Control
Almost everyone who tries this exercise sorts the wrong thing. Here is what Epictetus actually wrote, the step that makes it work, and a worked example you can copy.
You are lying awake over something you cannot do anything about. You know this. Knowing it has never once helped.
The Stoic response to that specific problem is about two thousand years old, takes three minutes, and is almost always taught in a way that does not work. The usual version — draw two columns, put things you control on the left — sounds complete and fails immediately in practice, because the thing you are actually worried about does not fit in either column.
This page covers what Epictetus wrote, why the standard exercise stalls, and a four-step version that doesn't.
What Epictetus actually wrote
The Enchiridion — a handbook of Epictetus' teaching compiled by his student Arrian — opens with the division and wastes no time getting to it:
Some things are in our control and others not. Things in our control are opinion, pursuit, desire, aversion, and, in a word, whatever are our own actions. Things not in our control are body, property, reputation, command, and, in one word, whatever are not our own actions.
— Epictetus, Enchiridion 1 (trans. Elizabeth Carter, 1758)
Two things in that passage get skipped, and both matter.
The first is how short the first list is. Epictetus is not saying "you control a lot, focus on that." He is saying you control your judgements, your intentions, what you go towards and what you avoid — and essentially nothing else. Not your body. Not your reputation. Not your position. The Greek phrase is eph' hēmin, "up to us," and the set it covers is far smaller than most people expect on first reading.
The second is the phrase our own actions. Epictetus locates control in the faculty of choice itself — prohairesis — not in what the choice achieves. Your decision to speak up in the meeting is yours. Whether anyone listens is not. That seam runs through everything below.
The mistake that makes the exercise fail
Ask someone to sort "my job" into two columns and watch what happens. They stall, because a job is not one thing. It is a manager, a salary, a commute, a set of tasks, a fear about next quarter, and a story about whether they are doing well enough. Some of that is theirs. Most is not. Sorting it as a single object is impossible, so people either give up or write job in the right-hand column and feel worse than when they started.
You cannot sort a situation. You can only sort its parts.
That is the whole difference between an exercise that works and one that feels like a party trick. Everything else here is scaffolding around that one step.
The four-step sort
Run it on paper, in a notes app, or in your head once you know it. Roughly three minutes.
Step 1 — Write the worry as one sentence
In the words you would actually use, not therapeutic ones. "I'm scared they're going to let me go" beats "I am experiencing job insecurity." The vaguer the sentence, the worse the sort.
Step 2 — Break it into components
List every distinct piece of the worry as its own line. Aim for six to ten. Include the things that feel too obvious to write down, and the things that feel too embarrassing.
This is the step everyone skips, and the reason the exercise fails when they do.
Step 3 — Sort each component
Two columns: up to me and not up to me. Judge each line on its own. Three rules make this faster:
- The past is never up to you. How you answered the question in the interview last Tuesday belongs in the right-hand column, permanently. It is finished. Most people burn more energy here than anywhere else.
- Other people are never up to you. Not their opinion, not their decision, not their mood.
- What you make something mean is always up to you. This line belongs in the left column every single time, and it is the one people never think to write down. Separating the event from the meaning you added to it has its own method — see Stoic impressions.
Step 4 — Convert the left column into next actions
Every line in the "up to me" column becomes a sentence starting with a verb, doable this week. If a line can't become an action, it wasn't in the right column.
Then stop. The right-hand column does not get a plan. That is the point of having sorted it. What to do with a right-hand column you keep re-arguing with is amor fati.
If one item in the right-hand column keeps pulling at you after the sort — a specific loss you cannot stop circling — that is a different problem, and there is a different exercise for it: premeditatio malorum, the Stoic rehearsal of the thing you fear.
A worked example
Step 1. "I interviewed nine days ago, they said they'd get back to me this week, and I've checked my email about forty times today."
Step 2 and 3. Broken into components and sorted:
| Component | Where it goes |
|---|---|
| Whether they offer me the role | Not up to me |
| How I answered their questions last Tuesday | Not up to me — it's in the past |
| Whether the role is even still funded | Not up to me |
| Whether the hiring manager liked me | Not up to me |
| How often I check my inbox | Up to me |
| Whether I send a short follow-up note | Up to me |
| Whether I keep applying elsewhere while I wait | Up to me |
| What I decide the silence means | Up to me |
| How I'll respond if the answer is no | Up to me |
Step 4. The left column becomes:
- Move email to twice a day, morning and 5pm.
- Send a four-line follow-up tomorrow morning. Then no more contact.
- Send two more applications this week regardless of the outcome.
- Silence means their process is slow. It does not mean a decision has been made about me.
- If it's a no, ask for one piece of specific feedback.
Notice what happened. The original worry — will they offer me the job — is still completely unresolved and still sits in the right-hand column, where it always belonged. Nothing about the situation changed. What changed is that there are now five things to do, and the forty inbox checks have somewhere else to go.
Notice also the two lines doing the most work: what I decide the silence means, and how often I check my inbox. Neither is the thing you were worried about. Both are entirely yours. The exercise is not a way of solving the problem; it is a way of finding the parts of it that will actually move.
"But I have some control"
This is the standard objection, and it is a fair one. You have some influence over whether you get the job — you prepared, you showed up, you answered well. Calling that "not up to me" feels like a dodge.
In 2008 William B. Irvine proposed a trichotomy of control in A Guide to the Good Life: things we fully control, things we don't control at all, and a third category of things we partly influence. For partial-influence items, he suggests internalising the goal — aiming at preparing thoroughly rather than at getting the offer.
Classical Stoicism reaches the same behaviour by a different route, and it is worth knowing because it is cleaner. The Stoics did not split the difference. They kept two categories and added a reserve clause — acting fully while holding the result loosely. Seneca describes the sage undertaking things with the qualification if nothing interferes. You commit completely to the preparation, which is entirely yours, and you make no claim on the outcome, which is entirely not.
The practical difference is small. The philosophical difference is that a third category invites you to keep negotiating with reality about how much of the outcome you own, which is precisely the argument that keeps you awake. Two piles, and a full commitment to the one that is yours.
Four ways this goes wrong
Sorting the situation instead of its parts. Covered above, and by far the most common. If your columns have three lines in them, go back to step two.
Using it to suppress a feeling. If you finish the sort feeling worse and slightly fraudulent, check whether you were sorting or arguing. The Stoics did not claim you can decide not to feel things. They claimed judgements are revisable, which is a much narrower and more defensible claim. The sort redirects attention; it does not delete grief, fear or anger, and treating it as a mood-fixing device will make you distrust it.
Reading "not up to me" as "doesn't matter." These are unrelated. Whether someone you love recovers is not up to you and matters enormously. The right-hand column is a statement about where your effort can land, not about what deserves your care. The largest items that live there permanently — illness, time, mortality — have their own practice in memento mori.
Running it once. This is a daily practice with a small effect each time, not a one-off insight. The value is cumulative and comes from noticing, over weeks, how consistently the same worry keeps landing in the right-hand column — which is an argument for keeping the sorts somewhere you can read back, and the reason Stoic journaling and this exercise belong together.
When the dichotomy is the wrong tool
It is worth being straight about the limits, because the internet's version of Stoicism rarely is.
The dichotomy is not an argument for passivity, and it is not a reason to accept mistreatment. Epictetus was born into slavery and taught in Rome after being freed; a man in that position was not counselling acquiescence to whatever happens. The distinction is between your response, which is always yours, and the outcome, which is not. Injustice you can act against goes squarely in the left-hand column, as action.
It is also not a way to reduce how much you depend on the things in the right-hand column. Sorting tells you a comfort is outside your control; it does nothing about how badly you would take losing it. That is voluntary discomfort.
It is also not a scale corrector. If something is genuinely yours to act on but has grown far past its real size in your head, sorting it again will not help — that is what the view from above is for.
It is also not a treatment. If a worry is running your sleep for weeks, or the sort keeps producing an empty left column no matter how carefully you break the problem down, that is information — and it points towards a doctor or a therapist rather than a longer session with a notebook. Philosophy is good at aiming attention. It is not a substitute for care.
Where to start
Pick the thing you were already thinking about before you opened this page. Write it as one sentence. Break it into eight parts. Sort them, and turn the left column into verbs.
If you get six components and four of them are past events, that alone is worth the three minutes.
Common questions
What is the dichotomy of control in simple terms?
It is Epictetus' division of everything you encounter into two piles: what your own judgement and choice control, and everything else. Your effort, your response and what you decide something means are in the first pile. Outcomes, other people's behaviour, your reputation, your body and the past are all in the second. The practice is to spend your attention on the first pile only.
Did Epictetus actually say this?
Yes. It opens the Enchiridion, the handbook of his teaching compiled by his student Arrian: 'Some things are in our control and others not.' He lists opinion, pursuit, desire and aversion as ours, and body, property, reputation and command as not ours.
What is the difference between the dichotomy and the trichotomy of control?
The trichotomy is a modern addition proposed by William B. Irvine in 2008, adding a third category for things we partly influence but do not determine, such as the result of a job interview. Classical Stoicism handles the same problem differently: the effort is fully yours, the outcome is not yours at all, and you commit to the effort while holding the result loosely. Both aim at the same behaviour; the two-pile version is closer to the original text.
How long does the exercise take?
Three to five minutes once you know the four steps. The first time takes longer because breaking a worry into components is unfamiliar. It is designed to be short enough to run daily, which matters more than running it thoroughly once.
Isn't this just telling yourself not to care?
No, and that misreading is the most common way the exercise fails. Sorting something into the 'not up to me' column is a decision about where to aim your effort, not a claim that it does not matter or that you should feel nothing about it. Epictetus was born into slavery and was not preaching acceptance of everything that happens.
