An egoist can be won over by being respected, a crazy person can be won over by allowing him to behave in an insane manner and a wise person can be won over by truth.

He shall despise none, but hear the opinions of all. A wise man shall make use of even a child's sensible utterance.

A wise man should not divulge the formula of a medicine which he has well prepared; an act of charity which he has performed; domestic conflicts; private affairs with his wife; poorly prepared food he may have been offered; or slang he may have heard.

The wise man should restrain his senses like the crane and accomplish his purpose with due knowledge of his place, time and ability.

A fool despises good counsel, but a wise man takes it to heart.

The man who is truly wise knows that he knows very little.
