Famous quotes containing the words angle of, angle, repose and/or materials:
“So much symmetry!
Like the pale angle of time
And eternity.
The great shape labored and fell.”
—N. Scott Momaday (b. 1934)
“From whichever angle one looks at it, the application of racial theories remains a striking proof of the lowered demands of public opinion upon the purity of critical judgment.”
—Johan Huizinga (1872–1945)
“I grow savager and savager every day, as if fed on raw meat, and my tameness is only the repose of untamableness. I dream of looking abroad summer and winter, with free gaze, from some mountain-side,... to be nature looking into nature with such easy sympathy as the blue-eyed grass in the meadow looks in the face of the sky. From some such recess I would put forth sublime thoughts daily, as the plant puts forth leaves.”
—Henry David Thoreau (1817–1862)
“He was no specialist except in the relation of things.... He took most of his materials at second hand.... But no matter who mined the gold, the image and superscription are his.”
—Woodrow Wilson (1856–1924)
