Famous quotes containing the word stroke:
“He will not idly dance at his work who has wood to cut and cord before nightfall in the short days of winter; but every stroke will be husbanded, and ring soberly through the wood; and so will the strokes of that scholar’s pen, which at evening record the story of the day, ring soberly, yet cheerily, on the ear of the reader, long after the echoes of his axe have died away.”
—Henry David Thoreau (1817–1862)
“At stroke of midnight soul cannot endure
A bodily or mental furniture.
What can she take until her Master give!
Where can she look until He make the show!
What can she know until He bid her know!
How can she live till in her blood He live!”
—William Butler Yeats (1865–1939)
“Now what sort of man or woman or monster would stroke a centipede I have ever seen? “And here is my good big centipede!” If such a man exists, I say kill him without more ado. He is a traitor to the human race.”
—William Burroughs (b. 1914)
