Virtue is not left to stand alone. He who practices it will have neighbors.

Things that are done, it is needless to speak about…things that are past, it is needless to blame.

When you know a thing, to hold that you know it; and when you do not know a thing, to allow that you do not know it – this is knowledge.

I have not seen a person who loved virtue, or one who hated what was not virtuous. He who loved virtue would esteem nothing above it.

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.

The superior man…does not set his mind either for anything, or against anything; what is right he will follow.

The cautious seldom err.

Learning without thought is labor lost; thought without learning is perilous.
