Famous quotes containing the word stroke:
“Every new stroke of civilization has cost the lives of countless brave men, who have fallen defeated by the “dragon,” in their efforts to win the apples of the Hesperides, or the fleece of gold. Fallen in their efforts to overcome the old, half sordid savagery of the lower stages of creation, and win the next stage.”
—D.H. (David Herbert)
“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)
“The five kings count the dead but do not soften
The crusted wound nor stroke the brow;
A hand rules pity as a hand rules heaven;
Hands have no tears to flow.”
—Dylan Thomas (1914–1953)
