Famous quotes containing the word cities:
“Whilst we want cities as the centres where the best things are found, cities degrade us by magnifying trifles.”
—Ralph Waldo Emerson (1803–1882)
“In great cities men are brought together by the desire of gain. They are not in a state of co-operation, but of isolation, as to the making of fortunes; and for all the rest they are careless of neighbours. Christianity teaches us to love our neighbour as ourself; modern society acknowledges no neighbour.”
—Benjamin Disraeli (1804–1881)
“We are a most solitary people, and we live, repelled by one another, in the gray, outcast cities of Cain.”
—Edward Dahlberg (1900–1977)
