Have no friends not equal to yourself.

Knowing what's correct and not doing it, it's the worst cowardice.

The superior man, even when he is not moving, has a feeling of reverence, and while he speaks not, he has the feeling of truthfulness.

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

The superior man is distressed by the limitations of his ability; he is not distressed by the fact that men do not recognize the ability that he has.
