War is never anything less than accelerated technological change. (p. 102) - Marshall McLuhan

All of man's artefacts, whether hardware or software, whether bulldozers or laws of chemistry, are alike linguistic in structure and intent. (p. 227)

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.

Every mode of technology is a reflex of our most intimate psychological experience. (p. 171)
