"Some things are within our power, others are not."
"Within our power are opinion, impulse, desire, aversion – in short, everything that is our own doing. Not within our power are the body, reputation, authority – in short, everything that is not our own doing." — Epictetus, Enchiridion, Chapter 1
Historical Context
Epictetus did not write these words. He spoke them.
Born around 50 CE as a slave in Hierapolis, he belonged to a freedman of Emperor Nero. He owned nothing. Not even his own body – according to one account, his master deliberately broke his leg to test his composure. Epictetus is said to have replied only: "You will break it." And when it broke: "Did I not tell you that you would break it?"
This equanimity was neither coincidence nor suppression. It was the result of a precise philosophical distinction that Epictetus made the absolute foundation of his thought. His student Arrian transcribed Epictetus's lectures – this is how the Enchiridion (literally: "handbook") and the more extensive Diatribē came into being. Composed around 108 CE, they were addressed not to professors of philosophy, but to people who wanted to learn how to live.
The teaching was not new. Zeno of Citium, founder of the Stoa around 300 BCE, and later Chrysippus had already distinguished between what is one's own (ta eph' hēmin) and what is alien (ouk eph' hēmin). But Epictetus did not leave this as an academic concept – he made it a tool for survival.
The Core Meaning
What lies within our power? Epictetus is precise: our judgments, our intentions, our desires, our aversions. That is all. Not little – but not more, either.
What does not lie within our power: health, fame, wealth, the outcome of events, how other people think or act toward us. Even one's own body, strictly speaking, belongs to the external world. It can fall ill. It will die.
The decisive point: Epictetus does not say that health is unimportant or that wealth is a matter of indifference. He says that these things are unreliable. They can be taken from us. Whoever builds their well-being upon them builds on sand.
What truly belongs to us is the attitude with which we meet whatever happens. Marcus Aurelius, who as emperor embodied the precise external opposite of Epictetus's situation, wrote in his Meditations (Book 4, Chapter 3):
"People seek retreats for themselves – in the country, by the sea, in the mountains. That is an ordinary longing. But you can retreat into yourself at any moment."
This is the same insight in different words: the only impregnable refuge is one's own faculty of judgment.
Seneca puts it even more sharply in his Epistulae Morales (Letter 1):
"Vindico te tibi" – Reclaim yourself for yourself.
This is not about withdrawing from the world. It is about seeing clearly what the world can take from us – and what it cannot.
The most common misreading of this teaching is that it leads to passivity. The opposite is true. Whoever no longer wastes energy trying to control uncontrollable things suddenly has all their energy available for what actually lies within their power. The dichotomy liberates – it does not paralyze.
Contemporary Relevance
Imagine you are waiting for a response that will decide your promotion. You gave everything. The presentation went well. The conversation went well. And now – nothing. Silence. Waiting.
What lies within your power? You spoke, acted, prepared. That has already happened. The judgment of the other person does not lie within your power. Neither does their bias, their mood, or the internal politics of their organization.
The Stoic question is not: How do I force this outcome in my direction? The Stoic question is: Did I do what was within my power, with full commitment?
This sounds like resignation. It is the opposite. It is the only attitude that preserves genuine agency – because it does not invest energy in fear, rumination, and attempts at control, but rather in the next step that is actually possible.
This distinction is also so powerful because it applies to every domain of life. To relationships: you can be sincere, open, and present – but you cannot control whether the other person stays. To health: you can live wisely – but you cannot guarantee that you will not fall ill. To reputation: you can act with integrity – but you cannot govern what others think of you.
Modern people often do not suffer because they do too little. They suffer because they feel responsible for things that were never within their power. This produces a diffuse, chronic tension for which there is no solution – because the problem has been framed incorrectly.
The Dichotomy of Control is a diagnostic tool. Apply it to every thought that burdens you: Does this lie within my power? If yes: act. If no: release it – not out of indifference, but out of clarity.
Daily Impulse
Today, try to ask a single question at every moment of discomfort – anger, worry, frustration: Does what is occupying me right now lie within my power?
Write it down if you like. Two columns. Left: what I can control. Right: what I cannot control. Then direct your attention consistently toward the left column – and practice letting go of the right one, not because it is unimportant, but because it is not yours.
