Famous quotes containing the word cities:
“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)
“Again and again I am brought up against it, and again and again I resist it: I don’t want to believe it, even though it is almost palpable: the vast majority lack an intellectual conscience; indeed, it often seems to me that to demand such a thing is to be in the most populous cities as solitary as in the desert.”
—Friedrich Nietzsche (1844–1900)
“We are in danger ... of making our cities places where business goes on but where life, in its real sense, is lost.”
—Hubert H. Humphrey (1911–1978)
