When a man's knowledge is sufficient to attain, and his virtue is not sufficient to enable him to hold, whatever he may have gained, he will lose again.

What you do not want done to yourself, do not do to others.

When we see men of worth, we should think of equaling them; when we see men of a contrary character, we should turn inwards and examine ourselves.

What the superior man seeks is in himself; What the mean man seeks is in others.
