The 1956 Film Invasion Of The Body Snatchers: How True art Reveals the Invisible Effects of Electricity
A Student of Technology asks:
Mr. Thall, you've often explained that genuine art reveals what people cannot perceive in their own technological environment. What does the 1956 science fiction film Invasion of the Body Snatchers reveal about the electric age?
Nelson S. Thall replies:
The real body snatcher is electricity. Its discarnate effect transforms us into images without bodies. This invasion began around the middle of the nineteenth century with the electric telegraph, which separated human communication from the physical presence of the communicator. With the telegraph came the unnoticed emergence of what Professor Marshall McLuhan called Mass Man. The telephone extended our voices beyond our bodies. Radio brought bodiless voices from distant lands into our daily environment. Television gave those bodiless voices the appearance of bodies. Cable television, computers, the internet, and smartphones progressively intensified this process. Every extension of ourselves is simultaneously an amplification and an amputation. Electric circuitry projects our senses and nervous systems outward at the speed of light, leaving the physical body behind. McLuhan called the human being produced by this electronic environment discarnate man. We are turned into electronic images and information. Our identities are detached from our physical bodies, converted into data, and stored in electronic databanks.
The pods in the film and electronic technology work in opposite directions, yet arrive at the same place. The pods keep the body and empty it of the person. Electronic technology keeps the image and leaves the body behind. Like the film's invasion, our electric invasion is largely invisible, spreads throughout the entire community, and remains unrecognized by those already transformed. This is precisely how the technological environment operated then and continues its invasion today. Its influence extends far beyond individual users, transforming the entire human environment, including our perceptions, relationships, and identities, turning individual man into Mass Man. The body snatchers are the visible figure. Electricity is the hidden ground.
True art frequently reveals the effects of an environment before its inhabitants become conscious of it. When Invasion of the Body Snatchers appeared in 1956, the electric invasion had already been underway for more than a century. The film was therefore both an artistic revelation of an existing technological condition and a prophetic foreshadowing of its ultimate consequences. Its audiences could recognize the terrifying loss of human identity on the screen without recognizing the sensory transformation occurring in their own lives. The very extensions that amplify our powers also numb our awareness of what has been amputated. This is what I call the TechnoTrap™. (See my forthcoming book, TechnoTrap: Outsmarting the Age of AI with Marshall McLuhan's Laws of Media.) Self-amputation forbids self-recognition. Had we been schooled in the principles of Technology Ecology, we might have told the boys in the laboratory to scrap the invention. Instead, we welcomed the real body snatcher into every corner of our existence. This invasion succeeded because the numbing effects of electricity prevented us from recognizing the invasion itself.
