Famous quotes containing the word cities:
“This is not only a war of soldiers in uniform. It is a war of the people, of all the people, and it must be fought not only on the battlefield but in the cities and the villages, in the factories and on the farms, in the home and in the heart of every man, woman and child who loves freedom.”
—Arthur Wimperis (1874–1953)
“What care though rival cities soar
Along the stormy coast,
Penn’s town, New York, Baltimore,
If Boston knew the most!”
—Ralph Waldo Emerson (1803–1882)
“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)
