In a broad sense, it refers to the psychological attributes that people generally have, including that part of the psychological attributes shared by people and other animals. Whether it is the essential psychological attributes of human beings or the attributes shared by human beings and animals, since they are all common psychological attributes of human beings, such attributes cannot be acquired results, but only human nature, which belongs to unconditional reflection and is the free expression of truth on human beings.

The sages worked out the rules of "good" behavior, and the wiser men, the strong men, did not follow the sages' advice, but let the ignorant people follow it. (The ignorant people were all ordinary people, from the literate and thoughtless men of letters, the wise men, to the good people.)Humanity is the unity of purpose and wisdom, and the process of using one's own wisdom to achieve one's own purpose.
