Integrity
This week you are learning about integrity, the Stoic concept the Greeks called "homonoia" in its social sense, but which the Stoics grounded more personally in what Epictetus called "prohairesis" (your power of choice and character) being fully aligned with your outward life. In plain terms, integrity means that who you are in private and who you appear to be in public are the same person, with no gap between them. It is worth learning because that gap, however small, is a constant source of anxiety, self-betrayal, and quiet shame; closing it is one of the most reliable paths to genuine self-respect.
Passage
Don't let it be possible for any one to say of you truthfully that you are not simple and good, but let him be a liar who thinks any of these things about you. And this entirely rests with you.
— Marcus Aurelius, Meditations X.32
Reflection
Marcus now turns the lens outward in a way that actually points back at you: make it so that anyone who calls you dishonest or two-faced is simply lying. This is integrity framed as a personal standard rather than a reputation to manage. Notice the last four words of the passage: 'this entirely rests with you.' That phrase is the Stoic concept of prohairesis, your power of choice, the one thing no one can take from you. Your character is not shaped by circumstance or by what others assume; it is shaped by every small decision you make about how to act. Integrity, then, is not a trait you either have or lack; it is something you choose, repeatedly, in ordinary moments.

What is one recurring situation in your life where you tend to hand your integrity over to circumstance, telling yourself 'I had no choice,' and what would it look like to make a deliberate choice there instead?
Practice
The Liar Test
Think of one person in your life who sees you regularly. Write down three things you would want them to be able to say about your character with full confidence. Then, for each one, write honestly whether your behavior over the past week has made those things easy or hard to say. No self-punishment; just clear seeing.
