Askêsis: Stoic training and voluntary discomfort
Introduction
There's a difference between knowing what you ought to do and being able to do it when the moment arrives. Everyone knows they shouldn't fire back at an irritating email, and everyone has done it. That gap between knowledge and conduct is exactly the problem the Stoics set out to solve.
Their answer was the concept of askêsis: training. The same word Greek athletes used for their preparation. For the Stoics, philosophy wasn't a subject you studied but a discipline you practiced, with repeated exercises and a very clear criterion for progress: how you behave, not how much you know.
Epictetus, who had been enslaved and had no patience for idle theory, put it bluntly: sheep don't vomit up the grass in front of the shepherd to prove how much they've eaten; they produce wool and milk. Likewise, don't display your reading: display the actions that come from having digested it.
You aren't what you know. You're what you do when the situation doesn't make it easy.
The three disciplines
Epictetus organized the training into three fields, and the structure is still usable as it stands:
The discipline of desire. Working on what we want and reject. The aim is to stop desiring what doesn't depend on us — because desiring it guarantees frustration — and to learn to want what there is. This is the territory of amor fati.
The discipline of action. Working on how we act toward others: doing what falls to us, with justice, without demanding that the outcome cooperate.
The discipline of assent. The subtlest. It consists of examining impressions before accepting them as true. Something happens, an automatic judgment appears — "this is terrible," "they're disrespecting me" — and the work is to insert a space between the impression and accepting it. Epictetus recommended saying to the impression: "wait, let me see what you are."
Voluntary discomfort
The best-known exercise, and the worst understood. Seneca recommended spending a few days eating the plainest food and wearing the coarsest clothes, then asking: "is this what I feared?" Musonius Rufus trained his students in cold, hunger and exertion.
The point isn't to suffer, and this is where the contemporary version goes astray. It isn't about demonstrating toughness or accumulating hardships like someone collecting merits. It's about two specific things:
Verifying experimentally that you can cope. Much of the fear of losing something disappears once you've lived without it for a few days and confirmed that the imagined catastrophe doesn't happen. It's a form of exposure, with the same logic clinical psychology uses today.
Recovering enjoyment of the ordinary. Continuous comfort dulls. After three days of plain food, a normal dinner tastes different. The exercise doesn't generate austerity: it generates the capacity to appreciate.
There's an important difference from real deprivation: voluntary discomfort is chosen and has an end date. Someone who is cold because they can't pay for heating isn't practicing philosophy. Confusing the two — and some popularization does — disrespects the second.
The exercises you can practice today
The evening review. Seneca reviewed each day before sleep: what you did well, what you did badly, what you'd do differently. Without self-flagellation. It's the highest-yield exercise of all and takes five minutes.
The morning preparation. Anticipate the difficulties of the day ahead: you'll meet irritating people, something will go wrong. Not to be pessimistic, but so that the setback arrives without the element of surprise.
The pause before the impression. When something upsets you, name what happened without the adjective. "I received an email pointing out a mistake" instead of "they're humiliating me." The fact and the judgment, separated.
One plain day. Once a month: basic food, no shopping, no optional comforts. One day, not a week. Afterward, note what you genuinely missed and what you didn't.
Refuse a small luxury on purpose. The second coffee, the purchase you fancy, the treat. Not always: once, deliberately, to confirm that the impulse passes on its own.
Sit with a silence. Don't respond immediately to what provokes you. It's the discipline of assent applied to modern life.
Cold showers, if they help you. They've become the emblem of internet Stoicism and deserve to be put in their place: a minor exercise, not the center of anything. They're worth the same as the others — confirming that you decide rather than comfort — not for their supposed metabolic effects.
How to know if you're progressing
Epictetus gave concrete criteria, and they're surprisingly practical:
- You complain less and blame others less.
- You talk about philosophy less and act more.
- You're less disturbed by what used to disturb you — not because you're suppressing it, but because you no longer judge it the same way.
- When you fail, you acknowledge it without drama and move on.
And one negative criterion worth keeping in mind: if the training is making you harsher toward others, something has gone wrong. Hardness toward yourself that turns into impatience with others isn't progress; it's something else.
The beginner's mistake
Starting with the spectacular. Long fasts, extreme routines, displayed deprivation. It's the Stoic version of the gym in January: lots of intensity, little continuity, and no real change of character.
The Stoics insisted on the opposite. Epictetus warned against proclaiming yourself a philosopher, and urged demonstrating it through small, sustained acts. Useful training is what you can repeat a thousand times: five minutes of review at bedtime is worth more than a heroic month followed by six of nothing.
Final thought
The gap between knowing and doing doesn't close by reading more; it closes by practicing. That's the whole argument of askêsis, and it's also what separates Stoicism from a collection of quotes: it was a discipline with exercises, not a catalogue of pleasant ideas. Start with the five-minute review before sleep and with separating fact from judgment when something upsets you. The rest — the cold, the plain food, the refused luxuries — is supplement. What actually gets trained is the response, and it's only trained by repeating it.
