Human nature is evil, and goodness is caused by intentional activity.

The nature of man is evil; what is good in him is artificial.

Since the nature of people is bad, to become corrected they must be taught by teachers and to be orderly they must acquire ritual and moral principles.

Sacrifice is a state of mind in which our thoughts turn with longing [toward Heaven, the Ancestors], It is the supreme expression of loyalty, love, and respect.

Human nature is such that people are born with a love of profit If they follow these inclinations, they will struggle and snatch from each other, and inclinations to defer or yield will die.

If knowledge and foresight are too penetrating and deep, unify them with ease and sincerity.

Therefore, a person should first be changed by a teacher's instructions, and guided by principles of ritual. Only then can he observe the rules of courtesy and humility, obey the conventions and rules of society, and achieve order.
