At the essence of pornography is the image of flesh used as a drug, a way of numbing psychic pain. But this drug lasts only as long as the man stares at the image. . . . In pornographic perception, each gesture, each word, each image, is read first and foremost through sexuality. Love or tenderness, pity or compassion, become subsumed by, and are made subservient to, a “greater” deity, a more powerful force. . . . The addict to pornography desires to be blinded, to live in a dream. Those in the thrall of pornography try to eliminate from their consciousness the world outside pornography, and this includes everything from their family and friends or last Sunday’s sermon to the political situation in the Middle East. In engaging in such elimination the viewer reduces himself. He becomes stupid.
