“McLuhan contends that all media - in and of themselves and regardless of the messages they communicate - exert a compelling influence on man and society. Prehistoric, or tribal, man existed in a harmonious balance of the senses, perceiving the world equally through hearing, smell, touch, sight and taste. But technological innovations are extensions of human abilities and senses that alter this sensory balance - an alteration that, in turn, inexorable reshapes the society that created the technology.”
