If you lose hope, somehow you lose the vitality that keeps moving, you lose that courage to be, that quality that helps you go on in spite of it all. And so today I still have a dream.

We must work passionately and indefatigably to bridge the gulf between our scientific progress and our moral progress. One of the great problems of mankind is that we suffer from a poverty of the spirit which stands in glaring contrast to our scientific and technological abundance. The richer we have become materially, the poorer we have become morally and spiritually.

Sooner or later, all the peoples of the world will have to discover a way to live together in peace, and thereby transform this pending cosmic elegy into a creative psalm of brotherhood.

To have peace in the world, men & nations must embrace the nonviolent assertion that ends and means must cohere.

Nonviolence means avoiding not only external physical violence but also internal violence of spirit. You not only refuse to shoot a man, but you refuse to hate him.

The trailblazers in human, academic, scientific and religious freedom have always been nonconformists.

Curtailment of free speech is rationalized on grounds that a more compelling American tradition forbids criticism of the government when the nation is at war... Nothing can be more destructive of our fundamental democratic traditions than the vicious effort to silence dissenters.
