[To the Editor of Playboy] Nudity is not realism. Compared to the clad figure, nudity is sculptural. Clothing is an anti-environment, a kind of weaponry, providing an enclosed space that is pictorial rather than sculptural. Sculpture is a tactile form that is both abstract and mathematical. When photographed, every feature and effect of the sculptural human body is slanted toward the visual rather than the tactile. In fact, high-definition photograph [sic] is so intense and specialized as to paralyze ordinary perception, and, hence, is accepted as a welcome tranquilizer. Of course, basic human sex attraction is olfactory, not photo-factory, hence the playful harmlessness and neutral innocence of your pictures….The apparent suddenness of the acceptance of nudity in public media today has nothing to do with any change of mind. What is changed is our sensory life as a result of living in a new information environment of electric tactility and involvement. It is this new environment reshaping the perceptual life of the Western world that relates Twiggy and Bucky and mini-skirts and LSD.
