Tolerance is a virtue that depends upon peace and strength.

If we cannot end now our differences, at least we can help make the world safe for diversity.

[Commencement Address at American University, June 10 1963]

Tolerance is the virtue of the man without convictions.

Human diversity makes tolerance more than a virtue; it makes it a requirement for survival. Celebrations of Life, 1981

People are very open-minded about new things--as long as they're exactly like the old ones.

As no roads are so rough as those that have just been mended, so no sinners are so intolerant as those that have just turned saints.
