We next imagine a more “evolved”, hence more flexible, setup; this time the camera, rather than being bolted onto its TV set, is attached to it by a “short leash”. Here, depending on the length and flexibility of the cord, it may be possible for the camera to twist around sufficiently to capture at least part of the TV screen in its viewfinder, giving rise to a truncated corridor. The biological counterpart to feedback of this level of sophistication may be the way our pet animals or even young children are slightly self-aware.
