Shall I tell you what knowledge is? It is to know both what one knows and what one does not know.

To know, is to know that you know nothing. That is the meaning of true knowledge. When you say something, say what you know. When you don't know something, say you don't know. That is knowledge.

If a man be under the influence of anger his conduct will not be correct.

True goodness springs from a man's own heart. All men are born good.

A good man does not worry about not being known by others, but rather is concerned about not knowing them.

If the people be led by laws, and uniformity sought to be given them by punishments, they will try to avoid the punishment, but have no sense of shame.

Be in harmony, yet be different.
