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.

One of the greatest casualties of the war in Vietnam is the Great Society... shot down on the battlefield of Vietnam.

One of the great liabilities of history is that all too many people fail to remain awake through great periods of social change.

This business of burning human beings with napalm, of filling our nation's homes with orphans and widows, of injecting poisonous drugs of hate into veins of peoples normally humane, of sending men home from dark and bloody battlefields physically handicapped and psychologically deranged, cannot be reconciled with wisdom, justice and love.

Now let me say that the next thing we must be concerned about if we are to have peace on earth and good will toward men is the nonviolent affirmation of the sacredness of all human life. Every man is somebody because he is a child of God.
