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

If there is no dull and determined effort, there will be no brilliant achievement.

If the impulse to daring and bravery is too fierce and violent, stay it with guidance and instruction.

If the blood humor is too strong and robust, calm it with balance and harmony.

The petty man is eager to make boasts, yet desires that others should believe in him. He enthusiastically engages in deception, yet wants others to have affection for him. He conducts himself like an animal, yet wants others to think well of him.

If what the heart approves conforms to proper patterns, then even if one’s desires are many, what harm would they be to good order?

I once tried standing up on my toes to see far out in the distance, but I found that I could see much farther by climbing to a high place.

The rigid cause themselves to be broken; the pliable cause themselves to be bound.

There are successful scholars, public-spirited scholars, upright scholars, cautious scholars, and those who are merely petty men.

Tell me and I forget. Teach me and I remember. Involve me and I learn.

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.

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.

Man’s nature is evil; goodness is the result of conscious activity.

Human nature refers to what is in people but which they cannot study or work at achieving.

The drum is surely the lord of music, is it not?

The person attempting to travel two roads at once will get nowhere.

Goodness is not the absence of disease. It is an intentional process for health.
