“With all our differences, we're not that different. Our quests are similar. The need for peace is not created by a document. It is created by a fundamental desire innate to all human beings, regardless of whether they are rich or poor, successful or unsuccessful. It is that innate desire that has, throughout history, pushed us again and again to find peace. The want, the concept, the idea of peace did not start this year or last year or the year before.”

To the Sultan of Johore. Quoted in "Key to Japan" - Page 289 - by Willard Price - 1946.

Remember love. The only hope for any of us is peace. Violence begets violence. If you want to get peace, you can get it as soon as you like if we all pull together. You're all geniuses and you're all beautiful. You don't need anybody to tell you who you are or what you are. You are what you are. Get out there and get peace. Think peace, live peace, and breathe peace and you'll get it as soon as you like. Okay?

Letter to friend Loren Hickerson (December 13, 1941)

Nobel Address (1991)
Context: Today, peace means the ascent from simple coexistence to cooperation and common creativity among countries and nations.
Peace is movement towards globality and universality of civilization. Never before has the idea that peace is indivisible been so true as it is now.
Peace is not unity in similarity but unity in diversity, in the comparison and conciliation of differences.
And, ideally, peace means the absence of violence. It is an ethical value.

Truman Library address (2006)
Context: Both security and development ultimately depend on respect for human rights and the rule of law.
— Although increasingly interdependent, our world continues to be divided — not only by economic differences, but also by religion and culture. That is not in itself a problem. Throughout history, human life has been enriched by diversity, and different communities have learnt from each other. But, if our different communities are to live together in peace we must stress also what unites us: our common humanity, and our shared belief that human dignity and rights should be protected by law.
