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)
“To walk through the ruined cities of Germany is to feel an actual doubt about the continuity of civilization.”
—George Orwell (1903–1950)
“I keep having the same experience and keep resisting it every time. I do not want to believe it although it is palpable: the great majority of people lacks an intellectual conscience. Indeed, it has often seemed to me as if anyone calling for an intellectual conscience were as lonely in the most densely populated cities as if he were in a desert.”
—Friedrich Nietzsche (1844–1900)
