Understanding Media

Quotes & Excerpts

If the nineteenth century was the age of the editorial chair, ours is the century of the psychiatrist’s couch. As extension of man the chair is a specialist ablation of the posterior, a sort of ablative absolute of backside, whereas the couch extends the integral being. The psychiatrist employs the couch, since it removes the temptation to express private points of view and obviates the need to rationalize events.

Jack Paar mentioned that he once had said to a young friend, “Why do you kids use ‘cool’ to mean ‘hot’?” The friend replied, “Because you folks used up the word ‘hot’ before we came along.”

A health director ...reported this week that a small mouse, which presumably had been watching television, attacked a little girl and her full-grown cat.... Both mouse and cat survived, and the incident is recorded here as a reminder that things seem to be changing.

In his splendid work Preface to Plato (Harvard University Press, 1963), Eric Havelock contrasts the oral and written cultures of the Greeks. By Plato’s time the written word had created a new environment that had begun to detribalize man. Previously the Greeks had grown up by benefit of the process of the tribal encyclopedia.They had memorized the poets. The poets provided specific operational wisdom for all the contingencies of life —Ann Landers in verse. With the advent of individual detribalized man, a new education was needed. Plato devised such a new program for literate men. It was based on the Ideas. With the phonetic alphabet, classified wisdom took over from the operational wisdom of Homer and Hesiod and the tribal encyclopedia. Education by classified data has been the Western program ever since.

The section on “media hot and cool” confused many reviewers of Understanding Media who were unable to recognize the very large structural changes in human outlook that are occurring today. Slang offers an immediate index to changing perception. Slang is based not on theories but on immediate experience. The student of media will not only value slang as a guide to changing perception, but he will also study media as bringing about new perceptual habits.

Western man acquired from the technology of literacy the power to act without reacting. The advantages of fragmenting himself in this way are seen in the case of the surgeon who would be quite helpless if he were to become humanly involved in his operation. We acquired the art of carrying out the most dangerous social operations with complete detachment. But our detachment was a posture of noninvolvement. In the electric age, when our central nervous system is technologically extended to involve us in the whole of mankind and to incorporate the whole of mankind in us, we necessarily participate, in depth, in the consequences of our every action. It is no longer possible to adopt the aloof and dissociated role of the literate Westerner.

When data move instantly, classification is too fragmentary.

The student today lives mythically and in depth. At school, however, he encounters a situation organized by means of classified information. The subjects are unrelated. They are visually conceived in terms of a blueprint. The student can find no possible means of involvement for himself, nor can he discover how the educational scene relates to the “mythic” world of electronically processed data and experience that he takes for granted.

The “content” of any medium is always another medium. The content of writing is speech, just as the written word is the content of print, and print is the content of the telegraph. If it is asked, “What is the content of speech?” it is necessary to say, “It is an actual process of thought, which is in itself nonverbal.”

The movie, by sheer speeding up the mechanical, carried us from the world of sequence and connections into the world of creative configuration and structure.

General Sarnoff went on to explain his attitude to the technology of print, saying that it was true that print caused much trash to circulate, but it had also disseminated the Bible and the thoughts of seers and philosophers. It has never occurred to General Sarnoff that any technology could do anything but add itself on to what we already are.

When IBM discovered that it was not in the business of making office equipment or business machines, but that it was in the business of processing information, then it began to navigate with clear vision.

Let us return to the electric light. Whether the light is being used for brain surgery or night baseball is a matter of indifference. It could be argued that these activities are in some way the “content” of the electric light, since they could not exist without the electric light.

MARSHALL MCLUHAN

This fact, characteristic of all media, means that the “content” of any medium is always another medium. The content of writing is speech, just as the written word is the content of print, and print is the content of the telegraph. If it is asked, “What is the content of speech?” it is necessary to say, “It is an actual process of thought, which is in itself nonverbal.”

MARSHALL MCLUHAN

Mental breakdown of varying degrees is the very common result of uprooting and inundation with new information and endless new patterns of information.

MARSHALL MCLUHAN

The effect of the medium is made strong and intense just because it is given another medium as “content.”

MARSHALL MCLUHAN

Our conventional response to all media, namely that it is how they are used that counts, is the numb stance of the technological idiot.

MARSHALL MCLUHAN

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.

If the criminal appears as a nonconformist who is unable to meet the demand of technology that we behave in uniform and continuous patterns, literate man is quite inclined to see others who cannot conform as somewhat pathetic.

[...] It is in our I.Q. testing that we have produced the greatest flood of misbegotten standards. Unaware of our typographic cultural bias, our testers assume that uniform and continuous habits are a sign of intelligence, thus eliminating the ear man and the tactile man.

In our own world as we become more aware of the effects of technology on psychic formation and manifestation, we are losing all confidence in our right to assign guilt.

C. G. Jung: Every Roman was surrounded by slaves. The slave and his psychology flooded ancient Italy, and every Roman became inwardly, and of course unwittingly, a slave. Because living constantly in the atmosphere of slaves, he became infected through the unconscious with their psychology. No one can shield himself from such an influence (Contributions to Analytical Psychology, London, 1928).

Pope Pius XII was deeply concerned that there be serious study of the media today. On February 17, 1950, he said: It is not an exaggeration to say that the future of modern society and the stability of its inner life depend in large part on the maintenance of an equilibrium between the strength of the techniques of communication and the capacity of the individual’s own reaction.

Print created individualism and nationalism in the sixteenth century.

MARSHALL MCLUHAN

He imagines that it is the response of our opinions that is relevant to the effect of media and technology in society, a “point of view” that is plainly the result of the typographic spell.

MARSHALL MCLUHAN

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.

For myth is the instant vision of a complex process that ordinarily extends over a long period.

An example of the disruptive impact of a hot technology succeeding a cool one is given by Robert Theobald in The Rich and the Poor. When Australian natives were given steel axes by the missionaries, their culture, based on the stone axe, collapsed. The stone axe had not only been scarce but had always been a basic status symbol of male importance. The missionaries provided quantities of sharp steel axes and gave them to women and children. The men had even to borrow these from the women, causing a collapse of male dignity. A tribal and feudal hierarchy of traditional kind collapses quickly when it meets any hot medium of the mechanical, uniform, and repetitive kind.

Were we to accept fully and directly every shock to our various structures of awareness, we would soon be nervous wrecks, doing double-takes and pressing panic buttons every minute.

MARSHALL MCLUHAN

Intensity or high definition engenders specialism and fragmentation in living as in entertainment, which explains why any intense experience must be “forgotten,” “censored,” and reduced to a very cool state before it can be “learned” or assimilated.

MARSHALL MCLUHAN

A hot medium is one that extends one single sense in “high definition.” High definition is the state of being well filled with data. A photograph is, visually, “high definition.” A cartoon is “low definition,” simply because very little visual information is provided. Telephone is a cool medium, or one of low definition, because the ear is given a meager amount of information. And speech is a cool medium of low definition, because so little is given and so much has to be filled in by the listener. On the other hand, hot media do not leave so much to be filled in or completed by the audience. Hot media are, therefore, low in participation, and cool media are high in participation or completion by the audience.
