Blake, in a word, sees man as fragmented by his technologies. But he insists that these technologies are self-amputations of our own organs. When so amputated, each organ becomes a closed system of great new intensity that hurls man into “martyrdoms and wars.” Moreover, Blake announces as his theme in Jerusalem the organs of perception: If Perceptive Organs vary, Objects of Perception seem to vary: If Perceptive Organs close, their Objects seem to close also. To behold, use or perceive any extension of ourselves in technological form is necessarily to embrace it.
