"A region is an area safely larger than the last one to whose problems we found no solution."

“Credentialing, not education, has become the primary business of North American universities.”

“It may be that we have become so feckless as a people that we no longer care how things do work, but only what kind of quick, easy outer impression they give. If so, there is little hope for our cities or probably for much else in our society. But I do not think this is so.”

“To science, not even the bark of a tree or a drop of pond water is dull or a handful of dirt banal. They all arouse awe and wonder.”

“As for really new ideas of any kind—no matter how ultimately profitable or otherwise successful some of them might prove to be—there is no leeway for such chancy trial, error and experimentation in the high-overhead economy of new construction. Old ideas can sometimes use new buildings. New ideas must use old buildings.”

“The other threat to the security of our tradition, I believe, lies at home. It is the current fear of radical ideas and of people who propound them. I do not agree with the extremists of either the left or the right, but I think they should be allowed to speak and to publish, both because they themselves have, and ought to have, rights, and once their rights are gone, the rights of the rest of us are hardly safe. Extremists typically want to squash not only those who disagree with them diametrically, but those who disagree with them at all. It seems to me that in every country where extremists of the left have gotten sufficiently in the saddle to squash the extremists of the right, they have ridden on to squash the center or terrorize it also. And the same goes for extremists of the right. I do not want that to happen in our country.”
