Famous quotes containing the words detached and/or objects:
“People in America, of course, live in all sorts of fashions, because they are foreigners, or unlucky, or depraved, or without ambition; people live like that, but Americans live in white detached houses with green shutters. Rigidly, blindly, the dream takes precedence.”
—Margaret Mead (1901–1978)
“The objects of a financier are, then, to secure an ample revenue; to impose it with judgment and equality; to employ it economically; and, when necessity obliges him to make use of credit, to secure its foundations in that instance, and for ever, by the clearness and candour of his proceedings, the exactness of his calculations, and the solidity of his funds.”
—Edmund Burke (1729–1797)
