Famous quotes containing the words deep and/or thought:
“And then a tall fat man with stringy hair
And a manner that was innocent of sin,
His galluses greasy, his eyes coldly gray,
Appeared, and with a gravely learned air
Spoke from the deep coherence of hell....”
—Allen Tate (1899–1979)
“I am less affected by their heroism who stood up for half an hour in the front line at Buena Vista, than by the steady and cheerful valor of the men who inhabit the snow-plow for their winter quarters; who have not merely the three-o’-clock-in-the-morning courage, which Bonaparte thought was the rarest, but whose courage does not go to rest so early, who go to sleep only when the storm sleeps or the sinews of their iron steed are frozen.”
—Henry David Thoreau (1817–1862)
