Technology extends and also amputates (McLUHAN)

“Technology can be described as an amplifier or an extension of the human body. The hammer is an extension of the fist, the knife is an extension of our teeth, TVs are exaggerated eyes and ears. Marshall McLuhan claimed that every extension results in an auto-amputation of another part.

“Every extension of mankind, especially technological extensions, has the effect of amputating or modifying some other extension[…] The extension of a technology like the automobile ‘amputates’ the need for a highly developed walking culture, which in turn causes cities and countries to develop in different ways. The telephone extends the voice, but also amputates the art of penmanship gained through regular correspondence. These are a few examples, and almost everything we can think of is subject to similar observations…We have become people who regularly praise all extensions, and minimize all amputations.””
