What Immanuel Kant has to say about what others have to say.
Saying “it doesn’t matter what others think” can mean two different things structurally. One meaning that you are not dependent on approval or authority is healthy. The other meaning is more problematic, you exempt your reasoning from public test. Kant insists that moral reasoning must remain capable of being shared, justified, and understood by other rational agents. If a rule cannot be explained in a way others could in principle accept, it starts drifting back toward private preference disguised as principle.
