Understanding Media: The Extensions of Man

by Marshall McLuhan

Physiologically there are abundant reasons for an extension of ourselves involving us in a state of numbness. Medical researchers like Hans Selye and Adolphe Jonas hold that all extensions of ourselves, in sickness or in health, are attempts to maintain equilibrium. Any extension of ourselves they regard as “autoamputation,” and they find that the autoamputative power or strategy is resorted to by the body when the perceptual power cannot locate or avoid the cause of irritation. Our language has many expressions that indicate this self-amputation that is imposed by various pressures. We speak of “wanting to jump out of my skin” or of “going out of my mind,” being “driven batty” or “flipping my lid.” And we often create artificial situations that rival the irritations and stresses of real life under controlled conditions of sport and play.
