Epictetus opens the Enchiridion by defining the fundamental distinction between what is and is not within our own power.

Epictetus opens by establishing reason as humanity's divine gift and uses dramatic examples—like the condemned Lateranus calmly accepting execution—to show what true Stoic courage looks like. Through debates with a grieving father, a tyrant, and a theater-going governor, he demonstrates that external circumstances, even death and tyranny, cannot touch a person's inner freedom. He attacks the philosophy of Epicurus for undermining both family duty and belief in divine providence, arguing that such ideas lead people away from virtue. Moving through his school lectures, Epictetus builds the case that dependence on wealth or imperial favor is simply another form of enslavement, debating a Roman senator who believes rank confers freedom. He holds up Diogenes and the exiled Agrippinus as living proof that true freedom comes from releasing all attachment to externals. The Enchiridion then distills these teachings into a practical opening distinction: only what lies within our own will is truly ours.

Epictetus closes the Enchiridion by recommending sayings from Euripides and Plato for readers to repeat in any difficult situation.

Epictetus confronts the Skeptics and develops his case for divine providence, arguing that God's simultaneous creation of colors and vision proves ongoing divine care for humanity. He addresses intimate philosophical challenges—suicide, personal guardian deities, the nature of misguided emotion as illustrated by Medea—and takes on moral hypocrites, including an adulterous scholar who attends his lecture. In exchanges with a visitor named Naso and a student seeking leave due to illness, Epictetus insists that philosophy's sole purpose is the elimination of frustrated desire, not academic credential. He warns against the dangerous habit of clinging to unexamined decisions, dismisses the Master Argument as a distraction from daily moral conduct, and argues that genuine love requires wisdom. He then probes the extreme demands of Cynicism and, in a rare moment of self-disclosure, admits to a senator that even he has not achieved full freedom. The Enchiridion closes with recommended philosophical sayings to carry through every difficult moment in life.

Epictetus urges readers to begin making philosophical progress immediately and to aspire to live as if striving to become Socrates.

Epictetus establishes the bedrock of his philosophy by asserting that reason makes humans morally accountable while releasing them from blame for external circumstances, and insists that education's highest goal is aligning human judgment with nature. He then reveals that the will itself is inviolable—not even a death threat can truly compel it—and argues that character, not circumstance, determines whether one lives well or poorly. Through practical classroom exercises, daily moral training, and a sharp critique of merely rhetorical philosophy, he shows that Stoicism is a lifelong discipline requiring constant and deliberate effort. Moving into Book Four and the Fragments, he defines freedom as the absence of compulsion, warns about the political dangers of careless speech under imperial rule, and names lack of persistence and self-control as philosophy's two greatest enemies. In the Enchiridion, he reframes grief by teaching readers to see everything—even beloved people—as temporarily on loan from God. The collection ends with an urgent call to begin the work of philosophical progress immediately, always aspiring toward the example of Socrates.
