“Mankind must put an end to war - or war will put an end to mankind.[Address before the United Nations, September 25 1961]”

“He who wars against the arts, wars not against nations, but against all mankind.”

“Peace is a daily, a weekly, a monthly process, gradually changing opinions, slowly eroding old barriers, quietly building new structures. And however undramatic the pursuit of peace, that pursuit must go on.[Address before the United Nations, September 20 1963]”

“Mankind is focused on earth; he is mostly interested in stupid things like wars or ideological absurdities. What he has to do is to concentrate on the universe, because the universe is a cosmic novel that he must read fully, that he must understand fully and that in the end he must rewrite it!”

“To a mankind that recognizes the equality of man everywhere, every war becomes a civil war.”

“The courage to put an end to war, to see the abysmal stupidity of it, is certainly no less than that needed to start one.”
