Famous quotes containing the word cities:
“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)
“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)
“The cities are the principal home and seat of the human group. They are the coral colony for Man, the collective being.”
—Alfred Döblin (1878–1957)
