Famous quotes containing the word cities:
“Today as in the time of Pliny and Columella, the hyacinth flourishes in Wales, the periwinkle in Illyria, the daisy on the ruins of Numantia; while around them cities have changed their masters and their names, collided and smashed, disappeared into nothingness, their peaceful generations have crossed down the ages as fresh and smiling as on the days of battle.”
—Edgar Quinet (1803–1875)
“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)
“The cities are the principal home and seat of the human group. They are the coral colony for Man, the collective being.”
—Alfred Döblin (1878–1957)
