Epictetus’s dichotomy of control

Epictetus’s dichotomy of control divides what happens to a person from the will with which that person meets it. Epictetus’s writings present the body and possessions as vulnerable to external power, while the capacity to act, refrain, seek, and avoid belongs to a person’s own domain. The principle becomes immediate for Conrad Hensley when he discovers it in a battered, disappointing book while imprisoned: his confinement can restrict his body, but it need not dictate his judgment or consent.

The distinction between what is and is not in one’s power

The distinction appears explicitly in the heading Conrad finds in Book I, Chapter 1: “On Things in Our Power and Things Not in Our Power.” Epictetus’s account, as Conrad reads it, begins from the vulnerability of embodied life. The body and possessions are not fully one’s own in the sense of being immune to other people or circumstance. Against them, the passage sets a portion of divinity: the “power to act and not to act,” together with the will to pursue or avoid. The dividing line is not between comfort and hardship, but between what can be taken or constrained and the faculty of choice that remains one’s responsibility.

The teaching consequently redirects blame and dependence. Epictetus’s passage says that a person who attends to this distinction “will blame no man” and “will flatter none.” Its promise is not that imprisonment or loss can be prevented. It is that external pressure need not determine a person’s inner response. The body may be constrained; the will is not therefore identical with the body, nor automatically subject to the same control.

Imprisonment as the test of the principle

Epictetus’s words address prisoners directly, making the subject more than an abstract philosophical exercise. The passage imagines a captor chaining a leg or threatening beheading, then draws a sharp boundary between the vulnerable body and the will. Its compact answer—“My leg you will chain-yes, but my will-no”—turns confinement into a test of what power can and cannot reach. Epictetus does not deny the force of a chain or the reality of death; he refuses the inference that bodily coercion amounts to complete dominion over a person.

The passage also frames hardship as training. A difficulty, Epictetus says, shows what people are; Zeus has matched the person with a formidable opponent so that he may become an Olympic conqueror, a result not achieved “without sweat.” In this account, adversity is neither proof that a person has lost all agency nor an easy route to achievement. It is the demanding circumstance in which the exercise of will becomes visible.

Conrad’s encounter with Epictetus

The principle reaches Conrad in conditions that echo its subject. On the top bunk in his prison pod, beneath the lizard screen, he tries to read a book that has already disappointed him. He had expected The Stoics’ Game, a work by Lucius Tombs, but the bookstore has sent The Stoics, an edition of writings by Epictetus, Marcus Aurelius, C. Musonius Rufus, and Zeno. A deputy has also left the book in limp, unbound pages. The wrong title and damaged object offer no comfort or escape; they are the immediate circumstances in which Conrad comes upon the idea.

At first he finds the introduction tedious. What arrests him is a detail about Epictetus’s life: sold into slavery as a boy, Epictetus spent time in prison, was tortured and crippled, and later became one of Rome’s greatest philosophers. Conrad then hurries through the introduction to reach Epictetus’s own words. The account of a thinker who had endured bodily coercion gives the prison passage a force that a detached summary could not have had for him.

Conrad reads that prisoners may lose freedom over their bodies and possessions while retaining a portion of divinity expressed in the will. The thought produces an “overwhelming thirst” for the words of a person he has never heard of before. Yet Five-O, his cellmate, calls him back to another lesson: the practical ways of jailhouse life. Conrad does not want to interrupt his reading, but also does not want to risk the goodwill he has newly gained from Five-O, so he decides he had better pay attention. The scene therefore leaves the principle in contact with prison’s immediate social demands: inward attention matters to Conrad, but it does not remove the need to navigate life with others.
