“The challenge to which these two groups responded was the interdependence of human kind, North and South, Rich and Pool, Industrialised and Rural, in the aftermath of the Second World War. To the United World College group it called for the establishment of a new kind of school where young people of all nations and backgrounds could live and learn together at the most formative period of their adolescence and so form those ties of friendship and understanding that would last them through their lives”

“Human kindness can be found in all groups, even those which as a whole it would be easy to condemn.”

“The tragedy in the lives of most of us is that we go through life walking down a high-walled land with people of our own kind, the same economic situation, the same national background and education and religious outlook. And beyond those walls, all humanity lies, unknown and unseen, and untouched by our restricted and impoverished lives.”

“There are two kinds of people in this world: those who know where their high school yearbook is and those who do not.”

“The Earth should not be cut up into hundreds of different sections, each inhabited by a self-defined segment of humanity that considers its own welfare and its own "national security" to be paramount above all other consideration.I am all for cultural diversity and would be willing to see each recognizable group value its cultural heritage. I am a New York patriot, for instance, and if I lived in Los Angeles, I would love to get together with other New York expatriates and sing "Give My Regards to Broadway."This sort of thing, however, should remain cultural and benign. I'm against it if it means that each group despises others and lusts to wipe them out. I'm against arming each little self-defined group with weapons with which to enforce its own prides and prejudices.The Earth faces environmental problems right now that threaten the imminent destruction of civilization and the end of the planet as a livable world. Humanity cannot afford to waste its financial and emotional resources on endless, meaningless quarrels between each group and all others. there must be a sense of globalism in which the world unites to solve the real problems that face all groups alike.Can that be done? The question is equivalent to: Can humanity survive?I am not a Zionist, then, because I don't believe in nations, and because Zionism merely sets up one more nation to trouble the world. It sets up one more nation to have "rights" and "demands" and "national security" and to feel it must guard itself against its neighbors.There are no nations! There is only humanity. And if we don't come to understand that right soon, there will be no nations, because there will be no humanity. ”
