Who knows the four realms of life?

There are four realms in life: natural realm, utilitarian realm, moral realm and heaven and earth realm.

Natural state: If people only follow instinct or custom, they have no understanding or little understanding. What he did meant nothing to him.

Utilitarianism: People are conscious and do all kinds of things for themselves. This does not mean that he must be immoral. He can do one thing, the consequences are beneficial to others, and his motivation is self-interest. So all kinds of things he has done are of utilitarian significance to him.

Moral realm: man knows the existence of society and he is a member of it. This society is a whole, and he is a part of it. With this understanding, he does all kinds of things for the benefit of society, or, as Confucianism says, he does things for the sake of "righteousness without profit." He is really a moral person, and what he does is a moral behavior that conforms to strict moral significance. Everything he does has moral significance. Moral realm has moral value.

The realm of heaven and earth (philosophical realm): people realize that there is a bigger whole outside the whole society, and that is the universe. He is not only a member of society but also a member of the universe. He is a citizen of social organizations, and at the same time, he is what Mencius called "Heaven and Man". With this understanding, he did all kinds of things for the benefit of the universe. He understands the significance of what he has done and realizes that he is doing what he has done. The realm of heaven and earth has super moral value.
