Those who make peaceful revolution impossible will make violent revolution inevitable.

Let us examine our attitude toward peace itself. Too many of us think it is impossible. Too many think it unreal. But that is a dangerous, defeatist belief. It leads to the conclusion that war is inevitable, that mankind is doomed, that we are gripped by forces we cannot control. We need not accept that view. Our problems are manmade; therefore they can be solved by man. And man can be as big as be wants. No problem of human destiny is beyond human beings.

For if Freedom and Communism were to compete for mans allegiance in a world at peace, I would look to the future with ever increasing confidence.

Sure it's a big job; but I don't know anyone who can do it better than I can.

Change is the law of life. And those who look only to the past or present are certain to miss the future.

Those [presidents] who were strongest intellectually were also strongest spiritually.

Sincerity is always subject to proof.
