Famous quotes containing the word cities:
“Satire is born of the cities it denounces.”
—Mason Cooley (b. 1927)
“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)
“In bombers named for girls, we burned
The cities we had learned about in school—
Till our lives wore out; our bodies lay among
The people we had killed and never seen.”
—Randall Jarrell (1914–1965)
