“Every man is a volume if you know how to read him.”

Error is discipline through which we advance.

If you light a lamp for somebody, it will also brighten your path.

Important principles may, and must, be inflexible.

We must be as courteous to a man as we are to a picture, which we are willing to give the advantage of a good light.

To lead people walk behind them.

The awareness of our own strength makes us modest.
