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.
When people lack teachers, their tendencies are not corrected when they do not have ritual and moral principles, then their lawlessness is not controlled.
Quarreling over food and drink, having neither scruples nor shame, not knowing right from wrong, not trying to avoid death or injury, not fearful of greater strength or of greater numbers, greedily aware only of food and drink – such is the bravery of the dog and boar.
Thus, anybody who follows this nature and gives way its states will be led into quarrels and conflicts, and go against the conventions and rules of society, and will end up a criminal.
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.
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.
