Marshall McLuhan Distant Early Warning Card Deck
Six years before Brian Eno and Peter Schmidt designed their first pack of Oblique Strategies cards—a set of random aphorisms meant to clear creative blocks—communication theorist and philosopher Marshall McLuhan had designed a very similar deck in 1969, this one with a more direct nod to the classic playing card deck.
The name of the card deck, Distant Early Warning, was a reference to the 3,000 mile long DEW Line, a system of 63 radar stations that acted as an early detection invasion buffer during the Cold War. And in his 1964 book Understand Media, McLuhan explained,
“I think of art, at its most significant, as a DEW line, a Distant Early Warning system that can always be relied on to tell the old culture what is beginning to happen to it.”
And so with help from advertising and publishing guru Eugene Schwartz, The Marshall McLuhan DEW-Line Newsletter and its spinoff deck of cards was born. Schwartz saw the newsletter much like we see blogs today: a very immediate way of disseminating information, deeper than television and faster than books. The newsletter lasted only two years, came in several forms (one issue was a set of slides, another a record), and represents the height of “McLuhan Mania” in American culture. Business and thought leaders were its target audience.
Much like Oblique Strategies (you can still find vintage versions online), the instructions for Distant Early Warning (also available online here) suggest that the user think of a personal or business problem, shuffle the deck, choose a card and interpret its meaning. Although divinatory cards have long been a part of western culture, the idea of indeterminacy and consulting the I Ching was very much in vogue through artists like John Cage.
