“Do not do to others what you do not want done to yourself.”Confucius · Analecte · -450 · XV, 24
Your own aversion is the moral compass: what you couldn't bear, impose on no one.
This is the golden rule in its negative form: instead of prescribing what to do, it forbids what you yourself would refuse. Its mechanism is moral imagination — your own aversion serves as the gauge of what is harmful. For instance, if you wouldn't want to be badmouthed behind your back, don't badmouth others; if you hate being ignored, don't ignore someone asking for help.
The negative rule has a hidden advantage: it forces you to know yourself first. Before judging an act toward someone else, you must know what hurts you. That turns every decision into a small act of self-observation. If a colleague texts you late at night and you hate it, you already have your answer. No theories needed, just honesty about your own dislikes. And where your aversion differs from someone else's, the next question appears: how do you find out what is unbearable for someone whose tastes differ from yours?
Why it matters It works as a quick test in everyday decisions, when there's no time for elaborate ethical reasoning.
