Famous quotes containing the word cities:
“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 a most solitary people, and we live, repelled by one another, in the gray, outcast cities of Cain.”
—Edward Dahlberg (1900–1977)
“Such poverty as we have today in all our great cities degrades the poor, and infects with its degradation the whole neighborhood in which they live. And whatever can degrade a neighborhood can degrade a country and a continent and finally the whole civilized world, which is only a large neighborhood.”
—George Bernard Shaw (1856–1950)
