Now, we see what we are shown. We have gotten used to being shown no matter what, within or beyond the limited range of human sight. This habituation to the monopoly of visualization-on-command strongly suggests that only those things that can in some way be visualized, recorded, and replayed at will are part of reality...The result is a strange mistrusts of our own eyes, a disposition to take as real only that which is mechanically displayed in a photograph, a statistical curve, or a table. Eyewitness testimony must be "substantiated" by records that have been acquired, and can be stored and then shown.
