We know it because democracy alone has constructed an unlimited civilization capable of infinite progress in the improvement of human life.

Favor comes because for a brief moment in the great space of human change and progress some general human purpose finds in him a satisfactory embodiment.

If we make ourselves worthy of America's ideals, if we do not forget that our nation was founded on the premise that all men are creatures of God's making, the world will come to know that it is free men who carry forward the true promise of human progress and dignity.

Arms alone can give the world no permanent peace, no confident security. Arms are solely for defense - to protect from violent assault what we already have. They are only a costly insurance. They cannot add to human progress.

Throughout America's adventure in free government, our basic purposes have been to keep the peace; to foster progress in human achievement, and to enhance liberty, dignity, and integrity among people and among nations.

The human race cannot make progress without idealism.
