What Is Askesis?
The word askesis comes from the ancient Greek askein, meaning to exercise, to train, or to practise a craft with care. In its earliest use it referred to the disciplined training of an athlete or an artisan. Over time, Greek philosophers adopted it to describe something more demanding: the deliberate, sustained practice of shaping one’s own character.
If you have ever wondered why Stoic philosophy feels less like a set of ideas and more like a way of living, askesis is a large part of the answer. The ancient schools did not think virtue could be reasoned into existence. It had to be practised, repeated, and tested, much as a musician practises scales not to think about music, but to embody it.
Askesis in the Ancient Schools
The Cynics: Training Through Discomfort
The earliest philosophers to make askesis central to their lives were the Cynics, particularly Diogenes of Sinope (c. 412–323 BCE). The Cynics believed that conventional comfort softened character and obscured what was truly good. Their askesis was deliberately harsh: sleeping rough, wearing minimal clothing in winter, eating simply, and refusing social status. The aim was not suffering for its own sake, but freedom. By training themselves to need very little, they could not be manipulated or broken by the loss of it.
This sounds extreme, and it was. But the underlying logic is recognisable. If you never practise being without something, you cannot honestly claim to be free of it.
The Stoics: Disciplined Attention and Voluntary Hardship
The Stoics inherited the Cynic spirit but softened its edges. For thinkers such as Epictetus, Marcus Aurelius, and Musonius Rufus, askesis took several forms.
Prosoche, or attention to the self, was the daily practice of watching one’s own thoughts and impulses before acting on them. This is not passive self-criticism but active self-knowledge: noticing when fear, anger, or desire is steering behaviour, and choosing otherwise.
Voluntary hardship was also recommended. Musonius Rufus, whose lectures survive in fragmentary form, encouraged students to eat plainly, endure cold, and do physical labour. Marcus Aurelius, writing privately in his Meditations, repeatedly reminded himself to rise early, eat simply, and resist the pull of luxury. These were not punishments. They were rehearsals for the inevitable difficulties life brings without warning.
Negative visualisation, sometimes called premeditatio malorum, is perhaps the best-known Stoic exercise today. By spending a few moments imagining the loss of things you value, you reduce their psychological grip on you and cultivate genuine appreciation for what you have. It is a form of mental askesis: training the imagination against complacency.
If you want to explore the Stoic books that describe these practices in depth, the guides to the best Stoicism books for beginners and the best books on Stoicism are good starting points. For Marcus Aurelius in particular, see the overview of the best translations of the Meditations.
Askesis Beyond Greece
The concept is not uniquely Greek. Buddhist practice includes structured disciplines of meditation, ethical restraint, and mindful attention that serve a parallel purpose: loosening the grip of habit and conditioning so that clearer awareness can emerge. Confucian self-cultivation, with its emphasis on daily self-examination and ritual practice, carries a similar logic. Even the Taoist idea of wu wei, acting in harmony with things rather than forcing them, involves a kind of inner training, a practised letting-go rather than passive indifference.
You can read more about some of these parallel ideas in the pieces on what the Tao is and what karma means in Buddhism.

What Askesis Is Not
It is worth being clear about what this practice does not mean, because the word has gathered some misleading associations.
Askesis is not self-punishment. Deliberate hardship is a tool, not a virtue in itself. A Stoic who went hungry to feel morally superior would have missed the point entirely. The aim is always greater freedom and clearer judgement, not mortification.
It is not emotional suppression. A common misreading of Stoicism treats it as a philosophy of feeling nothing. In fact, the Stoics distinguished between passions (reactive, unconsidered emotions that cloud judgement) and eupatheiai (well-reasoned emotional responses that are entirely welcome). Askesis trains you to respond rather than merely react. The goal is richer emotional experience, not a flattened one.
It is not withdrawal from life. The Stoics in particular were emphatic that philosophy must be lived in the world, in relationships, work, and civic life, not in retreat from them.
Why Askesis Still Matters
There is something quietly radical about the idea that character is built through practice rather than inherited or simply chosen. Most of us know, intellectually, what we value. Askesis is the bridge between knowing and actually living accordingly.
The practical implications are modest and within reach. You do not need to sleep on a stone floor. But you might eat more simply for a week and notice what that reveals about your relationship with comfort. You might practise sitting with an uncomfortable feeling rather than immediately distracting yourself from it. You might spend a few minutes each morning asking which of your habits are genuinely chosen and which have simply accumulated.
These small acts of deliberate attention are, in their modest way, askesis. They are the ancient practice stripped to its essence: training the self, on purpose, so that life does not train it for you by default.
If you are working on building habits of reflection and gratitude alongside this kind of self-discipline, the piece on how to practise gratitude offers some grounded approaches that pair naturally with Stoic exercises.
A Short Summary
- Askesis means deliberate, disciplined practice aimed at forming good character.
- It was central to the Cynics, the Stoics, and many other ancient schools.
- Stoic askesis includes self-observation, voluntary hardship, and negative visualisation.
- It is not self-punishment, emotional suppression, or withdrawal from ordinary life.
- Its core insight: virtue cannot only be understood; it must be practised until it becomes second nature.
