Famous quotes containing the word cities:
“If I be false, or swerve a hair from truth,
When time is old and hath forgot itself,
When waterdrops have worn the stones of Troy,
And blind oblivion swallowed cities up,
And mighty states characterless are grated
To dusty nothing, yet let memory
From false to false among false maids in love
Upbraid my falsehood.”
—William Shakespeare (1564–1616)
“Whilst we want cities as the centres where the best things are found, cities degrade us by magnifying trifles.”
—Ralph Waldo Emerson (1803–1882)
“We are a most solitary people, and we live, repelled by one another, in the gray, outcast cities of Cain.”
—Edward Dahlberg (1900–1977)
