“You see, proteins, as I probably needn't tell you, are immensely complicated groupings of amino acids and certain other specialized compounds, arranged in intricate three-dimensional patterns that are as unstable as sunbeams on a cloudy day. It is this instability that is life, since it is forever changing its position in an effort to maintain its identity--in the manner of a long rod balanced on an acrobat's nose.”

“It is the obvious which is so difficult to see most of the time. People say 'It's as plain as the nose on your face.' But how much of the nose on your face can you see, unless someone holds a mirror up to you?”

“I tell you it's deadly when you start thinking your wife might be right.”

“Don't you see? It's Galaxy-wide. It's a worship of the past. It's a deterioration - a stagnation!”

“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. ”

“A wall is happy when it is well designed, when it rests firmly on its foundation, when its symmetry balances its part and produces no unpleasant stresses. Good design can be worked out on the mathematical principles of mechanics.”

“I can't bear to hear a human being spoken of with contempt just because of his group identification...It's these respectable people here who create those hooligans out there.”
