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.

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

Those whose character is mean and vicious will rouse others to animosity against them.

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.

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

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.

When people lack teachers, their tendencies are not corrected; when they do not have ritual and moral principles, then their lawlessness is not controlled.
