Marshall McLuhan’s theories of technology as an extension of the body  

        It seems to me that Marshall McLuhan loved wordplay. The title The Medium is the Massage is no exception. Maybe he was making a statement about the way that the media massage or beat us, or perhaps he was making a pun on the new "mass-age" - the era of message to masses. McLuhan made this wordplay the subtitle of Understanding Media, his best known, best-selling book. It is easy to overlook how far-reaching McLuhan’s thesis is, partly due to our habit of accepting metaphors as metaphors. However McLuhan believed that metaphors, similes, puns, and other literary tricks have the power to reveal the true nature of things, rather than just accelerate the writer’s task of getting points and information across.  

        Therefore, McLuhan's investigations in his Understanding Media: The Extensions of Man (New York: McGraw-Hill, 1964) deal with the media and its effects. To McLuhan, any medium is an extension (actually, a virtual extension, or "prosthesis") of our bodies, minds, or beings (just as a prosthetic arm is a physical extension of the body, clothes are an extension of the skin; the bicycle, and the car extend the human foot; also, the computer can be thought of as extending our central nervous system, and  even more “Man becomes…the sex organs of the machine world, as the bee of the plant world, enabling it to fecundate and to evolve ever new forms.” (Understanding Media p. 56)  

McLuhan was primarily concerned with changes in cultures and societies under the influence of the media. He distinguished three Ages of Man:

        In the first place - The Preliterate, or Tribal, era of very non-hierarchical, democratic societies, relying on the ear, as opposed to the eye, to keep us "sensitive, hyperaesthetic, and all-inclusive"; the dependence on the ear held us closer to "the seamless web of tribal kinship and interdependence in which all members of the group lived in harmony" (Playboy interview, 1969   ).

        Secondly -The Gutenberg Age where “The Gutenberg Revolution" intensified the effects of the older (writing) technology. According to McLuhan, Gutenberg's invention (which was the idea of splitting up of the text into individual components such as lower and upper case letters, punctuation marks, ligatures and abbreviations, based upon the tradition of medieval scribes), immensely extended the impact of the phonetic alphabet, inevitably forcing "man to comprehend in a linear, uniform, connected, continuous fashion." Of course it was a revolution when Gutenberg invented the technique to have books printed instead of the old handwriting. It meant that the free word suddenly was widely spread. After Gutenberg the ideas of life and of freedom was not any longer a privilege for monks in the monasteries The phonetic alphabet  as an extension of both our bodies and minds, set off a whole chain reaction of changes in human societies. The phonetic alphabet distressed out tribal sensorium, fragmenting us and turning us into psychically indigent "individuals", or "units." It thus led to hierarchy in societies, and also to linear thought, centralization, and everything from logic to nationalism. In other words, everything that happened to the world happened because of the new communication form –the print. Gutenberg´s importance for the democratic development of our societies cannot be overestimated. Today, however, we are all taking part in a second revolution, the digital revolution, which McLuhan outlined as The Electronic Age which we will have at least the same impact, perhaps even bigger than the Gutenberg innovation some hundred years ago.

        And finally, in The Electronic Age of Retribalized Man (involving full sensory involvement) that "instant communication" online will bring people together again:  by being able to speak to practically anyone in the world at any time, people will "retribalize." The relationship of man’s senses to media isn’t just a matter of importance but of mental response resulting in social consequences in which any changes in the hierarchy of man’s senses changes man himself. Industrial or visual man, who is divided into rational parts by way of economics, is the ultimate individualist because of the partitions he has learned from the alphabet ...
