A day will come when markets, open to trade, and minds, open to ideas, will become the sole battlefield.

I'm not in the world to guard my own life, but to guard souls

One cannot resist an idea whose time has come.

A wretched woman is more unfortunate than a wretched man.

We must never fear robbers or murderers. They are dangers from outside, small dangers. It is ourselves we have to fear. Prejudice is the real robber, vice the real murderer. Why should we be troubled by a threat to our person or our pocket? What we have to beware of is the threat to our souls'.

The cruel of heart have their own black happiness.

If nobody loved, the sun would go out.
