A superior person wields discretionary power over people, chattel and property in a particular range with determination to become a final cause. A mediocre person has some expertise ordered by the chain of command, so that a mediocre person becomes an efficient or formal cause under the social contract. An inferior person adopts a slave mentality under expansive dogmas to become a material cause.

Still, where dogma fails to comfort people, superiors are justified in the use of brutality and violence that serve to provide a good example. Like the concept of moral slavery the social contract only serves to rationalization the dehumanization of people with a mob mentality therefore is destructive to human dignity. I submit the “rule of law” binds all people equally in the context of propositional attitudes that mean, “my liberty ends where the freedom of others begins". Only in this context can all people be considered equal under the law.

When a slave becomes a king, does that mean that anyone who thinks people fall into classes of "superior" and "inferior" must in fact be an idiot?

Morality is based on empathy. A healthy dose of positive thinking probably helps.
