Interview on The David Frost Show (14 June 1969)
Context: We're trying to sell peace, like a product, you know, and sell it like people sell soap or soft drinks. And it's the only way to get people aware that peace is possible, and it isn't just inevitable to have violence. Not just war — all forms of violence. People just accept it and think 'Oh, they did it, or Harold Wilson did it, or Nixon did it,' they're always scapegoating people. And it isn't Nixon's fault. We're all responsible for everything that goes on, you know, we're all responsible for Biafra and Hitler and everything. So we're just saying "SELL PEACE" — anybody interested in peace just stick it in the window. It's simple but it lets somebody else know that you want peace too, because you feel alone if you're the only one thinking 'wouldn't it be nice if there was peace and nobody was getting killed.' So advertise yourself that you're for peace if you believe in it.

On how he wants to be perceived as a writer in “Édouard Louis: 'I want to be a writer of violence. The more you talk about it, the more you can undo it'” https://www.theguardian.com/books/2018/jun/09/edouard-louis-i-want-to-be-a-writer-of-violence-the-more-you-talk-about-it-the-more-you-can-undo-it in The Guardian (2018 Jun 9)

Statement to the press in July 1969 after the release of the Plastic Ono Band's single "Give Peace a Chance", as quoted in The Beatles: An Oral History by David Pritchard and Alan Lysaght (1998) New York: Hyperion. ISBN: 0786864362. OCLC: 39093547. p. 285.
Context: It was just a gradual development over the years. Last year was "All You Need Is Love." This year it's "Give Peace a Chance." 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?

Context: When every young man refuses to go to war, you will have peace. As long as you fight for gain and greed, there will be no peace. As long as one person commits acts of violence for the sake of peace, you will have war. Unfortunately it is difficult to imagine that all the young men in all of the countries will refuse to go to war at the same time. And so you must work out what violence has wrought. Within the next hundred years, that time may come. Remember, you do not defend any idea with violence. There is no man who hates but that hatred is reflected outward and made physical. And there is no man who loves but that love is reflected outward and made physical.

Context: I know what you want. You want a story that won't surprise you. That will confirm what you already know. That won't make you see higher or further or differently. You want a flat story. An immobile story. You want dry, yeastless factuality.
