Famous quotes containing the words large and/or systems:
“Sensuality reconciles us with the human race. The misanthropy of the old is due in large part to the fading of the magic glow of desire.”
—Eric Hoffer (1902–1983)
“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)
