The Dichotomy of Control (Prohairesis)
This week you are learning the Dichotomy of Control, the idea at the heart of Stoic practice. The Greek word is prohairesis (say it: pro-HY-uh-ree-sis), which means your power of choice, your capacity to decide how you respond to anything that happens. The Stoics taught that everything in life falls into one of two categories: what is genuinely up to you (your judgements, desires, attitudes, and intentions) and what is not (your body, other people, outcomes, reputation, the weather, everything external). Once you see that line clearly, you can stop exhausting yourself fighting what you cannot control and start putting real energy into the one thing you actually own.
Passage
Under our control are moral purpose and all the acts of moral purpose; but not under our control are the body, the parts of the body, possessions, parents, brothers, children, country—in a word, all that with which we associate.
— Epictetus, Discourses 1.22.10
Reflection
Today Epictetus spells out the full map. Your moral purpose, meaning the way you use your prohairesis, is yours. Everything else, your body, your possessions, your family, your country, belongs to the 'not mine' column. This sounds harsh at first, because you love those people and care about those things. But Epictetus is not telling you to stop caring. He is telling you to see clearly where your power starts and stops, so that you do not build your inner life on ground that can be taken from you at any moment.

Practice
Category Check
For ten minutes today, pay attention to each thing that pulls at your attention, a notification, a worry, a hope, a task. For each one, ask a single quiet question: 'Is this asking me to govern something inside me or something outside me?' You do not need to fix anything; just notice which category each pull belongs to.
