Dikaiosyne — Justice
This week's concept is dikaiosyne, the Greek word for justice, which the Stoics understood as far more than fairness in a courtroom. For them, dikaiosyne means actively giving to others what they are owed: your honesty, your effort, your care, your right action in every relationship you inhabit. It is one of the four cardinal virtues, sitting alongside wisdom, courage, and self-discipline, and the Stoics considered it the most outward-facing of the four. This week you will learn what justice actually demands of you, why it is inseparable from living well, and how to practice it in the ordinary moments of your day.
Passage
Our duties are in general measured by our social relationships. He is a father. One is called upon to take care of him, to give way to him in all things, to submit when he reviles or strikes you. “But he is a bad father.” Did nature, then, bring you into relationship with a good father? No, but simply with a father. “My brother does me wrong.” Very well, then, maintain the relation that you have toward him; and do not consider what he is doing, but what you will have to do, if your moral purpose is to be in harmony with nature. For no one will harm you without your consent; you will have been harmed only when you think you are harmed. In this way, therefore, you will discover what duty to expect of your neighbour, your citizen, your commanding officer, if you acquire the habit of looking at your social relations with them.
— Epictetus, Handbook 30
Reflection
Epictetus grounds the whole week's teaching in specific, named relationships: father, brother, citizen, officer. His point is direct: your duty in any relationship is defined by the nature of that relationship, not by whether the other person is behaving well. A bad father is still a father; a wrongful brother is still your brother. This is dikaiosyne tested under pressure, because it is easy to be just toward people who are just toward you. Epictetus insists your moral purpose, what the Stoics called prohairesis (your capacity to choose and reason), must stay in harmony with nature regardless of what the other person does. Your justice is yours to maintain or abandon; it does not depend on theirs. This is not passivity; it is a refusal to let someone else's bad behaviour define your character.

Which relationship in your life right now is the hardest one in which to maintain your own just conduct, and what specifically makes it hard: is it anger, fear, exhaustion, or something else?
Practice
Name the Relationship, Name the Duty
Choose one difficult relationship, with a person who has treated you badly or whom you find hard to deal with. Write the heading: 'What this relationship is.' Then write one sentence describing what that relationship requires of you, independent of how the other person behaves. Keep it short and honest. Carry that sentence with you today.
