pictures, as we learn to read letters, is worth consideration. The extreme bias and distortion of our sense-lives by our technology would seem to be a fact that we prefer to ignore in our daily lives. Evidence that natives do not perceive in perspective or sense the third dimension seems to threaten the Western ego-image and structure, as many have found after a trip through the Ames Perception Laboratory at Ohio State University. This lab is arranged to reveal the various illusions we create for ourselves in what we consider to be "normal" visual perception. That we have accepted such bias and obliquity in a subliminal way through most of human history is clear enough. Just why we are no longer content to leave our experience in this subliminal state, and why many people have begun to get very conscious about the unconscious, is a question well worth investigation. People are nowadays much concerned to set their houses in order, a process of self-consciousness that has received large impetus from photography. William Henry Fox Talbot, delighting in Swiss scenery, began to reflect on the camera obscura and wrote that "it was during these thoughts that the idea occurred to me . . . how charming it would be if it were possible to cause these natural images to imprint themselves durably, and remain fixed on paper!" The printing press had, in the Renaissance, inspired a similar desire to give permanence to daily feelings and experience. The method Talbot devised was that of printing positives chemically from negatives, to yield an exactly repeatable image. Thus the roadblock that had impeded the Greek botanists and had defeated their successors was removed. Most of the sciences had been, from their origins, utterly handicapped by the lack of adequate nonverbal means of transmitting information. Today, even subatomic physics would be unable to develop without the photograph. The Sunday New York Times for June IS, 1958 reported:
