The world in which we live is geographically one. The challenge that we face today is to make it one in terms of brotherhood.

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.

I was not afraid of the words of the violent, but of the silence of the honest.

We have genuflected before the god of science only to find that it has given us the atomic bomb, producing fears and anxieties that science can never mitigate.

Violence is immoral because it thrives on hatred rather than love. It destroys community and makes brotherhood impossible. It leaves society in monologue rather than dialogue. Violence ends by defeating itself. It creates bitterness in the survivors and brutality in the destroyers.

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.

I'm concerned about a better world. I'm concerned about justice; I'm concerned about brotherhood; I'm concerned about truth. And when one is concerned about that, he can never advocate violence. For through violence you may murder a murderer, but you can't murder murder. Through violence you may murder a liar, but you can't establish truth. Through violence you may murder a hater, but you can't murder hate through violence. Darkness cannot put out darkness; only light can do that.
