Famous quotes containing the words surface and/or area:
“The surface of the earth is soft and impressible by the feet of men; and so with the paths which the mind travels. How worn and dusty, then, must be the highways of the world, how deep the ruts of tradition and conformity!”
—Henry David Thoreau (1817–1862)
“Prestige is the shadow of money and power. Where these are, there it is. Like the national market for soap or automobiles and the enlarged arena of federal power, the national cash-in area for prestige has grown, slowly being consolidated into a truly national system.”
—C. Wright Mills (1916–1962)
