Should Stoics practice voluntary discomfort?

Seneca raises the question himself. Writing in December, with Rome given over to the license of the Saturnalia, he wonders aloud whether he and his correspondent Lucilius should keep their ordinary habits or loosen them along with everyone else (Moral Letters Vol I 18.1 to 18.2). The question is not abstract for him. It is about how to live through one particular season without either joining the general excess or standing apart from it in a way that just becomes its own kind of display.

Epictetus answers a version of the same question more directly, and his answer has two parts that are easy to run together.

The first part is yes: discomfort can be practiced. Desire and aversion are pulled by strong habit toward externals, toward pleasure and away from pain, and Epictetus says a contrary habit has to be set against that pull deliberately. If you notice you are inclined to pleasure, incline the other way past the point of necessity, for the sake of practice. If you are averse to pain, rub up against that aversion on purpose, so that it loosens its hold on you (Discourses III 12). The aim named here is precise: to have desire and aversion free from restraint, meaning never disappointed and never caught by what you were trying to avoid. Voluntary hardship is training for that freedom, the same way a runner trains legs that will need to hold up under race conditions.

The second part is a caution, and it is where the popular picture of Stoic asceticism goes wrong. Epictetus is explicit that not every hard or dangerous exercise belongs in this training. Walking a tightrope is difficult and dangerous, and so is climbing a palm tree or embracing a statue in the cold, but none of that serves the goal. Exercises that are hard and dangerous but do not conduce to the actual work in front of us, he says, are not suitable for practice, and anyone who takes them up is no philosopher but a juggler performing for an audience (Discourses III 12). The point is not to be tough. It is to be free.

This is the same warning the Handbook gives in smaller form. If you have trained yourself to live on little, Epictetus says, do not congratulate yourself on it or announce it, and if you drink only water do not keep saying so. He adds a sharper instruction still: if the aim is real training in endurance, do it for yourself, not for an audience, and do not go grasping statues for effect. When you are badly thirsty, take a little water in your mouth, spit it out, and say nothing about it to anyone (Handbook 47). The comparison he offers is worth sitting with: the poor already bear hardship with more patience than most of us manage, and they do it without ceremony. That is the standard, not spectacle.

So the honest answer has two edges. Voluntary discomfort is a real Stoic practice, aimed at loosening the grip that pleasure and pain have on your desire and aversion, so that externals stop dictating what you chase and what you flee. But it fails as soon as it becomes a performance, a badge, or a stunt aimed at admiration rather than at freedom. The test Epictetus gives is simple to state and harder to apply: does this particular hardship conduce to the actual goal, living with desire and aversion unrestrained by what is not up to you, or does it just look impressive. If you want to try it, pick something small and ordinary, skip a comfort you would normally reach for automatically, and tell no one you did it.
