Famous quotes containing the word cities:
“This is not only a war of soldiers in uniform. It is a war of the people, of all the people, and it must be fought not only on the battlefield but in the cities and the villages, in the factories and on the farms, in the home and in the heart of every man, woman and child who loves freedom.”
—Arthur Wimperis (1874–1953)
“No doubt I shall go on writing, stumbling across tundras of unmeaning, planting words like bloody flags in my wake. Loose ends, things unrelated, shifts, nightmare journeys, cities arrived at and left, meetings, desertions, betrayals, all manner of unions, adulteries, triumphs, defeats ... these are the facts.”
—Alexander Trocchi (1925–1983)
“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)
