Famous quotes containing the words large and/or systems:
“In Europe art has to a large degree taken the place of religion. In America it seems rather to be science.”
—Johan Huizinga (1872–1945)
“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)
