Famous quotes containing the words large and/or systems:
“The newspapers, especially those in the East, are amazingly superficial and ... a large number of news gatherers are either cynics at heart or are following the orders and the policies of the owners of their papers.”
—Franklin D. Roosevelt (1882–1945)
“The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.”
—Jean Baudrillard (b. 1929)
