Famous quotes containing the words operating and/or systems:
“... the modern drama, operating through the double channel of dramatist and interpreter, affecting as it does both mind and heart, is the strongest force in developing social discontent, swelling the powerful tide of unrest that sweeps onward and over the dam of ignorance, prejudice, and superstition.”
—Emma Goldman (1869–1940)
“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)
