My country, 'tis of thee, sweet land of liberty, of thee I sing. Land where my fathers died, land of the pilgrim's pride, from every mountainside, let freedom ring.

Let us develop a kind of dangerous unselfishness.

Life's most persistent and urgent question is, 'What are you doing for others?'

Through our scientific and technological genius we've made of this world a neighborhood. And now through our moral and ethical commitment we must make of it a brotherhood. We must all learn to live together as brothers-or we will all perish together as fools.

Mankind's survival is dependent on man's ability to solve the problems of racial injustice, poverty, and war; the solution of these problems is in turn dependent upon man's squaring his moral progress with his scientific progress, and learning the practical art of living in harmony.

I refuse to accept the idea that the “isness” of man's present nature makes him morally incapable of reaching up for the eternal “oughtness” that forever confronts him.

We cannot walk alone.
