“It is no longer a choice between violence and nonviolence; it is either nonviolence or nonexistence.”

1968: The Year That Rocked the World

The Ballot or the Bullet (1964), Speech in Cleveland, Ohio (April 3, 1964)
Context: I don’t mean go out and get violent; but at the same time you should never be nonviolent unless you run into some nonviolence. I’m nonviolent with those who are nonviolent with me. But when you drop that violence on me, then you’ve made me go insane, and I’m not responsible for what I do. And that’s the way every Negro should get. Any time you know you’re within the law, within your legal rights, within your moral rights, in accord with justice, then die for what you believe in. But don’t die alone. Let your dying be reciprocal. This is what is meant by equality. What’s good for the goose is good for the gander.

1960s, Nobel Prize acceptance speech (1964)
Context: Nonviolence is the answer to the crucial political and moral questions of our time — the need for mankind to overcome oppression and violence without resorting to violence and oppression. Civilization and violence are antithetical concepts… Sooner or later all the people 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. If this is to be achieved, man must evolve for all human conflict a method which rejects revenge, aggression and retaliation. The foundation of such a method is love.

2011, Remarks on Egyptian political transition (February 2011)
Context: I know that a democratic Egypt can advance its role of responsible leadership not only in the region but around the world.
Egypt has played a pivotal role in human history for over 6,000 years.  But over the last few weeks, the wheel of history turned at a blinding pace as the Egyptian people demanded their universal rights.
We saw mothers and fathers carrying their children on their shoulders to show them what true freedom might look like.
We saw a young Egyptian say, “For the first time in my life, I really count.  My voice is heard.  Even though I’m only one person, this is the way real democracy works.”
We saw protesters chant “Selmiyya, selmiyya” — “We are peaceful” — again and again.
We saw a military that would not fire bullets at the people they were sworn to protect.
And we saw doctors and nurses rushing into the streets to care for those who were wounded, volunteers checking protesters to ensure that they were unarmed.
We saw people of faith praying together and chanting – “Muslims, Christians, We are one.”  And though we know that the strains between faiths still divide too many in this world and no single event will close that chasm immediately, these scenes remind us that we need not be defined by our differences.  We can be defined by the common humanity that we share.
And above all, we saw a new generation emerge — a generation that uses their own creativity and talent and technology to call for a government that represented their hopes and not their fears; a government that is responsive to their boundless aspirations.  One Egyptian put it simply:  Most people have discovered in the last few days…that they are worth something, and this cannot be taken away from them anymore, ever.
This is the power of human dignity, and it can never be denied. Egyptians have inspired us, and they’ve done so by putting the lie to the idea that justice is best gained through violence.  For in Egypt, it was the moral force of nonviolence — not terrorism, not mindless killing — but nonviolence, moral force that bent the arc of history toward justice once more.

1960s, Beyond Vietnam: A Time to Break Silence (1967)
Context: We still have a choice today: nonviolent coexistence or violent coannihilation. We must move past indecision to action. We must find new ways to speak for peace in Vietnam and 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.

The Paris Review interview (1958)
Context: The perfect ideal would be that a man who is essentially nonviolent would be able to defend himself against any form of violence. But this is very rare in life. But this raises one of the most important themes in Eternity, why Prewitt does not shoot back at the MPs who kill him as he tries to get back to his unit after his murder of Fatso Judson. You see, when Prewitt kills Fatso he is carrying the theory of vengeance by violence to its final logical end. But the thing is that Fatso doesn't even know why he is being killed; and when Prewitt sees that, he realizes what a fruitless thing he has done.
