Men of all social stations live together: they are equal in their desires, yet vary in their methods; they are equal in their passions, yet different in their intelligence; that is their nature-given vitality.
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.
Now it is human nature to want to eat to ones fill when hungry, to want to warm up when cold, to want to rest when tired. These all are a part of people’s emotional nature.
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.
