Famous quotes containing the word country:
“The city sleeps and the country sleeps,
The living sleep for their time, the dead sleep for their time,
The old husband sleeps by his wife and the young husband sleeps by his wife;
And these tend inward to me, and I tend outward to them,
And such as it is to be of these more or less I am,
And of these one and all I weave the song of myself.”
—Walt Whitman (1819–1892)
“That country where a man can be so crossed;
Can be so battered, badgered and destroyed
That he’s a loveless man....”
—William Butler Yeats (1865–1939)
