There’s a famous scene in the 1977 romcom Annie Hall, in which Woody Allen’s character grows irritated by a bespectacled bore, who is loudly pontificating on the theories of Marshall McLuhan. When Allen explodes, a verbal scuffle ensues, and Allen tells the bore, “you don’t know anything about Marshall McLuhan!” The man protests his academic credentials, whereupon Allen says, “I happen to have Mr McLuhan right here.”
Out steps the Canadian philosopher, immaculate in a light beige suit, to inform the bore: “I heard what you were saying. You know nothing of my work.”
One can partly sympathise with the bore. McLuhan’s work isn’t always easy to define. To read Understanding Media: The Extensions of Man (1964) is to fear that one’s mind might explode, as it is bombarded with assertions, ideas, moments of impenetrable wackiness, and illustrative snippets from literature and history. Today, it is also to be repeatedly startled by the relevance of the author’s thinking to our own era.
McLuhan, a game and dapper participant in the media that he dissected, died in his sleep in December 1980, aged 69. His most famous sound-bite was “the medium is the message”, and he was also known for his prediction that electric technology would have the power to contract the world into “a global village”.
Now, McLuhan appears before us as a kind of seer of the digital age. He instinctively understood that a new medium is not simply a tool of man, but has the ability to reshape human thought, society and culture according to its own inherent properties.
The book’s main point is that any new medium becomes part of humanity – an extension of our consciousness. “With the arrival of electric technology,” McLuhan writes, “man extended, or set outside himself, a live model of the central nervous system itself”.
This, for McLuhan, is ground on which to attack the argument that technology is simply a form of neutral tool, which individuals can choose to use for good or ill.
