Who said “The city is not a concrete jungle. It is a human zoo.”?

“Cities, like cats, will reveal themselves at night.”

“We do not look in great cities for our best morality.”

“No city should be too large for a man to walk out of in a morning.”

“The Metropolis should have been aborted long before it became New York, London or Tokyo.”

“To look at the cross-section of any plan of a big city is to look at something like the section of a fibrous tumor.”

“We never stop investigating. We are never satisfied that we know enough to get by. Every question we answer leads on to another question. This has become the greatest survival trick of our species.”

“We are, to put it mildly, in a mess, and there is a strong chance that we shall have exterminated ourselves by the end of the century. Our only consolation will have to be that, as a species, we have had an exciting term of office.”
