Famous quotes containing the word cities:
“Just as language has no longer anything in common with the thing it names, so the movements of most of the people who live in cities have lost their connexion with the earth; they hang, as it were, in the air, hover in all directions, and find no place where they can settle.”
—Rainer Maria Rilke (1875–1926)
“What care though rival cities soar
Along the stormy coast,
Penn’s town, New York, Baltimore,
If Boston knew the most!”
—Ralph Waldo Emerson (1803–1882)
“We are a most solitary people, and we live, repelled by one another, in the gray, outcast cities of Cain.”
—Edward Dahlberg (1900–1977)
