Famous quotes containing the words surface and/or area:
“When we are in love, the sentiment is too great to be contained whole within us; it radiates out to our beloved, finds in her a surface which stops it, forces it to return to its point of departure, and it is this rebound of our own tenderness which we call the other’s affection and which charms us more than when it first went out because we do not see that it comes from us.”
—Marcel Proust (1871–1922)
“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)
