Choose the better handle
Principle 43 from the Enchiridion
Choose the view that helps you respond without denying the problem. A difficult situation can be held in a way that makes good action harder or more possible.
Original Passage
Everything has two handles, the one by which it may be carried, the other by which it cannot. If your brother acts unjustly, don't lay hold on the action by the handle of his injustice, for by that it cannot be carried; but by the opposite, that he is your brother, that he was brought up with you; and thus you will lay hold on it, as it is to be carried.
Modern Interpretation
Epictetus says a difficult situation has more than one "handle." One way of holding it makes it heavier. Another may make it possible to deal with.
If we hold only the interpretation that makes us angriest, it becomes harder to act well.
That does not mean denying wrongdoing. We can acknowledge the unfairness while also remembering the relationship, its history, and any responsibilities that still exist. A wider view may make a better response possible.
In Practice
Here is one everyday case. A sibling behaves unfairly during a family argument. If the only thing you hold is the unfairness, the fight is likely to grow.
If you also remember that this person is your sibling, you may still be firm without deliberately destroying every chance of repairing the relationship.
Reflection Question
In your current conflict, which handle are you gripping? Is there another view that would help you act better without denying the problem?
