Famous quotes containing the word images:
“No healthy man, in his secret heart, is content with his destiny. He is tortured by dreams and images as a child is tortured by the thought of a state of existence in which it would live in a candy store and have two stomachs.”
—H.L. (Henry Lewis)
“... I am an instrument in the shape/of a woman trying to translate pulsations/into images for the relief of the body/and the reconstruction of the mind.”
—Adrienne Rich (b. 1929)
“What images are these
That turn dull-eyed away,
Or shift Time’s filthy load,
Straighten aged knees,
Hesitate or stay?
What heads shake or nod?”
—William Butler Yeats (1865–1939)
