Peace cannot be kept by force. It can only be achieved by understanding.

There is no way to peace; peace is the way.

In War: Resolution. In Defeat: Defiance. In Victory: Magnanimity. In Peace: Good Will.

I still believe that peace and plenty and happiness can be worked out some way. I am a fool.

I am not only a pacifist but a militant pacifist. I am willing to fight for peace. Nothing will end war unless the people themselves refuse to go to war.

Nothing can bring you peace but yourself.

It is impossible for me to reconcile myself to the idea of conversion after the style that goes on in India and elsewhere today. It is an error which is perhaps the greatest impediment to the world’s progress toward peace … Why should a Christian want to convert a Hindu to Christianity? Why should he not be satisfied if the Hindu is a good or godly man? January 30, 1937.

I'm a Muslim. I've been a Muslim for 20 years. . . . You know me. I'm a boxer. I've been called the greatest. People recognize me for being a boxer and a man of truth. I wouldn't be here representing Islam if it were terrorist. . . . I think all people should know the truth, come to recognize the truth. Islam is peace.

When things are investigated, then true knowledge is achieved;
When true knowledge is achieved, then the will becomes sincere;
When the will is sincere, then the heart is set right;
When the heart is set right, then the personal life is cultivated;
When the personal life is cultivated, then the family life is regulated;
When the family life is regulated, then the national life is orderly;
And when the national life is orderly, then there is peace in the world.

I regard myself as a soldier, though a soldier of peace.

Love is kind, love is patient

This is a novel somewhat in the telegraphic schizophrenic manner of tales of the planet Tralfamadore, where the flying saucers come from. Peace.

The United States, as the world knows, will never start a war. We do not want a war. We do not now expect a war. This generation of Americans has already had enough — more than enough — of war and hate and oppression. We shall be prepared if others wish it. We shall be alert to try to stop it. But we shall also do our part to build a world of peace where the weak are safe and the strong are just. We are not helpless before that task or hopeless of its success. Address at The American University, Washington D.C. (10 June 1963)

If we cannot end now our differences, at least we can make the world safe for diversity. For, in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's future. And we are all mortal. Address at The American University, Washington D.C. (10 June 1963)

What kind of peace do we seek? Not a Pax Americana enforced on the world by American weapons of war. Not the peace of the grave or the security of the slave. I am talking about genuine peace, the kind of peace that makes life on earth worth living, the kind that enables men and nations to grow and to hope and to build a better life for their children — not merely peace for Americans but peace for all men and women — not merely peace in our time but peace for all time. Address at The American University, Washington D.C. (10 June 1963)
