Famous quotes containing the word cities:
“Do you know what Agelisas said, when he was asked why the great city of Lacedomonie was not girded with walls? Because, pointing out the inhabitants and citizens of the city, so expert in military discipline and so strong and well armed: “Here,” he said, “are the walls of the city,” meaning that there is no wall but of bones, and that towns and cities can have no more secure nor stronger wall than the virtue of their citizens and inhabitants.”
—François Rabelais (1494–1553)
“An architect should live as little in cities as a painter. Send him to our hills, and let him study there what nature understands by a buttress, and what by a dome.”
—John Ruskin (1819–1900)
“Books may be burned and cities sacked, but truth like the yearning for freedom, lives in the hearts of humble men and women. The ultimate victory, the ultimate victory of tomorrow is with democracy; and true democracy with education, for no people in all the world can be kept eternally ignorant or eternally enslaved.”
—Franklin D. Roosevelt (1882–1945)
