Marcus Aurelius source guide · Duties Between People
Stoic Boundaries · A Duty Between People
Open this as a leaf in the Emperor’s Notebook, not as a detached definition. Treat a boundary as your chosen conduct and access decision, not a command over another person. The purpose is to notice the judgment being made, consult the named record, and decide what conduct can still be commanded.
On this page you will get a clear explanation, a way to examine the idea, exact evidence from public-domain Stoic texts, and links for continuing the study.
The matter: a duty tested between persons
Stoic Boundaries belongs here because it changes how a person names the event before acting. Begin with the bare occurrence, then write the prediction, demand, fear, or appetite laid over it.
This is a correction addressed to oneself. It does not require passivity, emotional numbness, or certainty about the outcome; it asks for an exact account of the choice still available.
Convene the ancient record
The evidence attached to this leaf comes from Cicero. Its working locators are Cicero, On Ends 3.18, Cicero, On Duties 1.8, and Cicero, On Ends 1.10. The voices remain attributed so that Marcus never silently absorbs another author.
Read the preserved wording before the interpretation. Ask what distinction the passage actually makes, what it leaves unresolved, and whether your first impression has claimed more than the source warrants.
Sources: Cicero, On Ends 3.18; Cicero, On Duties 1.8; Cicero, On Ends 1.10
Enter what remains under command
Enter The Law You Serve when the distinction must become conduct: Compare what you desire with the qualities you admire.
Write the next action narrowly enough to perform: what you will say, refuse, prepare, repair, or leave alone. Fortune includes another person’s reply, reputation, delay, and the final result.
Sources: Cicero, On Ends 3.18
Return without awarding a verdict
After the event, compare the vow with the action. Record what was learned about stoic boundaries without converting one outcome into a score for character.
A clean return names what happened, what belonged to choice, what did not, and the one rehearsal worth carrying into the next day.
What the primary texts say
These excerpts keep their work and exact locator so you can check the claim in context rather than accepting a detached quotation.
“He therefore, when he acts, judges that that is his duty; and because he is never deceived in forming his judgment, duty must be classed among neutral things;”
“Absolute duty we may, I presume, call right, for the Greeks call it kato/rqwma, while the ordinary duty they call kaqh=kon. And the meaning of those terms they fix thus: whatever is right they define as absolute duty, but mean duty, they say, is duty for the performance of which an adequate reason may be rendered.”
“For no one either despises, or hates, or avoids pleasure itself merely because it is pleasure, but because great pains overtake those men who do not understand how to pursue pleasure in a reasonable manner.”
Frequently asked questions
How should I use this notebook leaf on Stoic Boundaries?

Does this present Cicero as Marcus Aurelius?
No. Marcus is the permanent centre of the product, while every other ancient author remains explicitly named as a source in the wider Stoic record.
