Essential McLuhan 156 that uniform and continuous habits are a sign of intelligence, thus eliminating the ear man and the tactile man. C.P.Snow, reviewing a book of A.L.Rowse (The New York Times Book Review, December 24, 1961) on Appeasement and the road to Munich, describes the top level of British brains and experience in the 1930s. “Their I.Q.’s were much higher than usual among political bosses. Why were they such a disaster?” The view of Rowse, Snow approves: “They would not listen to warnings because they did not wish to hear.” Being anti-Red made it impossible for them to read the message of Hitler. But their failure was as nothing compared to our present one. The American stake in literacy as a technology or uniformity applied to every level of education, government, industry, and social life is totally threatened by the electric technology. The threat of Stalin or Hitler was external. The electric technology is within the gates, and we are numb, deaf, blind, and mute about its encounter with the Gutenberg technology, on and through which the American way of life was formed. It is, however, no time to suggest strategies when the threat has not even been acknowledged to exist. I am in the position of Louis Pasteur telling doctors that their greatest enemy was quite invisible, and quite unrecognized by them. Our conventional response to all media, namely that it is how they are used that counts, is the numb stance of the technological idiot. For the “content” of a medium is like the juicy piece of meat carried by the bur- glar to distract the watchdog of the mind. The effect of the medium is made strong and intense just because it is given another medium as “content.” The content of a movie is a novel or a play or an opera. The effect of the movie form is not related to its program content. The “content” of writing or print is speech, but the reader is almost entirely unaware either of print or of speech. Arnold Toynbee is innocent of any understanding of media as they have shaped history, but he is full of examples that the student of media can use. At one moment he can seriously suggest that adult education, such as the Workers Educational Association in Britain, is a useful counterforce to the popular press. Toynbee considers that although all of the oriental societies have in our time accepted the industrial technology and its political consequences: “On the cultural plane, however, there is no uniform corresponding tendency.” (Somervell, I. 267) This is like the voice of the literate man, floundering in a milieu of ads, who boasts, “Personally, I pay no attention to ads.” The spiritual and cultural reservations that the oriental peoples may have toward our technology will avail them not at all. The effects of technology do not occur at the level of opinions or concepts, but alter sense ratios or patterns of perception steadily and without any resistance. The serious artist is the only person able to encounter technology with impunity, just because he is an expert aware of the changes in sense perception. The operation of the money medium in seventeenth-century Japan had effects not unlike the operation of typography in the West. The
