Principle 30 from the Enchiridion
Epictetus teaches that every relationship carries duties, and our task is to fulfill our role with integrity.
Original Passage
Duties are universally measured by relations. Is anyone a father? If so, it is implied that the children should take care of him, submit to him in everything, patiently listen to his reproaches, his correction. But he is a bad father. Are you naturally entitled, then, to a good father? No, only to a father. Is a brother unjust? Well, keep your own situation towards him. Consider not what he does, but what you are to do to keep your own faculty of choice in a state conformable to nature. For another will not hurt you unless you please. You will then be hurt when you think you are hurt. In this manner, therefore, you will find, from the idea of a neighbor, a citizen, a general, the corresponding duties if you accustom yourself to contemplate the several relations.
Modern Interpretation
Epictetus teaches that roles carry duties. Parent, child, sibling, friend, citizen—each relation implies responsibilities for how we should act. Stoicism focuses less on controlling others and more on fulfilling our own part with integrity.
A key point is that another person's failure does not excuse yours. If someone is unfair, careless, or rude, your task is still to respond according to your values. Otherwise, you let their behavior determine your character.
This principle is practical and demanding. It asks, "What is my role here, and what action fits that role?" Not, "What did they do first?" That shift reduces reactive conflict and increases moral clarity.
You cannot choose others' conduct, but you can choose whether you remain faithful to your duties.
In Practice Today
A family member speaks harshly during a disagreement. Your impulse is to return equal harshness. A Stoic lens asks, "What is my role in this relationship?"
If your role includes respect and patience, you set a boundary without contempt. You can be firm while still fair. You do not excuse bad behavior, but you refuse to become it.
Your peace comes from acting according to your duty, not from winning every exchange.
Reflection Question
In a difficult relationship, what duty belongs to your role, regardless of how the other person behaves?
