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

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

If the quickness of the mind and the fluency of the tongue are too punctilious and sharp, moderate them in your activity and rest.

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.

When a man sees something desirable, he must reflect on the fact that with time it could come to involve what is detestable. When he sees something that is beneficial, he should reflect that sooner or later it, too, could come to involve harm.

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