Famous quotes containing the words monitor and/or probing:
“It is indeed typical that you Earth people refuse to believe in the superiority of any world but your own. Children looking into a magnifying glass, imagining the image you see is the image of your true size.”
—Franklin Coen. Joseph Newman. The Monitor (Douglas Spencer)
“Industrial societies turn their citizens into image-junkies; it is the most irresistible form of mental pollution. Poignant longings for beauty, for an end to probing below the surface, for a redemption and celebration of the body of the world. Ultimately, having an experience becomes identical with taking a photograph of it.”
—Susan Sontag (b. 1933)
