Through our scientific and technological genius, we have made of this world a neighborhood and yet we have not had the ethical commitment to make of it a brotherhood. But somehow, and in some way, we have got to do this. We must all learn to live together as brothers or we will all perish together as fools. We are tied together in the single garment of destiny, caught in an inescapable network of mutuality. And whatever affects one directly affects all indirectly. For some strange reason I can never be what I ought to be until you are what you ought to be. And you can never be what you ought to be until I am what I ought to be. This is the way God’s universe is made; this is the way it is structured.
John Donne caught it years ago and placed it in graphic terms: "No man is an island entire of itself. Every man is a piece of the continent, a part of the main." And he goes on toward the end to say, "Any man’s death diminishes me because I am involved in mankind; therefore never send to know for whom the bell tolls; it tolls for thee." We must see this, believe this, and live by it if we are to remain awake through a great revolution.

More recently I have come to see the need for the method of nonviolence in international relations. Although I was not yet convinced of its efficacy in conflicts between nations, I felt that while war could never be a positive good, it could serve as a negative good by preventing the spread and growth of an evil force. War, horrible as it is, might be preferable to surrender to a totalitarian system. But now I believe that the potential destructiveness of modern weapons totally rules out the possibility of war ever again achieving a negative good. If we assume that mankind has a right to survive then we must find an alternative to war and destruction. "Don't ever let anyone pull you so low as to hate them. We must use the weapon of love. We must have the compassion and understanding for those who hate us. We must realize so many people are taught to hate us that they are not totally responsible for their hate. But we stand in life at midnight; we are always on the threshold of a new dawn."
--Martin Luther King, Jr., "Pilgrimage to Nonviolence" in Strength to Love (1958)
We must move past indecision to action. We must find new ways to speak for peace in Vietnam [or now, Iraq and the Middle East] and for justice throughout the developing world, a world that borders on our doors. If we do not act, we shall surely be dragged down the long, dark, and shameful corridors of time reserved for those who possess power without compassion, might without morality, and strength without sight.
--Martin Luther King, Jr., "CONSCIENCE AND THE VIETNAM WAR" in The Trumpet of Conscience (1968)
