Use your eyes as if tomorrow you would become blind.

We cannot freely and wisely choose the right way for ourselves unless we know both good and evil.

I have walked with people whose eyes are full of light but who see nothing in sea or sky, nothing in city streets, nothing in books. It were far better to sail forever in the night of blindness with sense, and feeling, and mind, than to be content with the mere act of seeing. The only lightless dark is the night of darkness in ignorance and insensibility.

When we do the best we can, we never know what miracles await.

I do not want the peace which passeth understanding, I want the understanding which bringeth peace.

What can rulers, nobility and all the lords of the earth say to justify the horrible killing and maiming of twenty or thirty million valuable men who a short while ago ploughed, dug, wove, built, guided the traffic of the world, took their pleasure, loved their fellows, cherished their families, and feared naught?

The chief handicap of the blind is not blindness, but the attitude of seeing people towards them.
