Famous quotes containing the word stroke:
“So was produced this tragedy
In a far tower of ivory
Where, O young men, late in the night
All you who drink light and stroke the air
Come back, seeking the night, and cry
To strict Rapunzel to let down her hair.”
—Allen Tate (1899–1979)
“I believe that Harmon would be the easiest to defeat, though he might gain much strength from the Republicans. Clark would surely lose New York. I am beginning to feel that by some stroke of genius they may name Woodrow Wilson, and that seems a pretty hard tussle.”
—William Howard Taft (1857–1930)
“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)
