Growing up with TV results in stereotypes of language and attitudes representing a background of shared expressions, gestures, and values. To see in these only the negative, the low end, is easier than to acknowledge that previous backgrounds, constituted on the underlying structure of literacy, have become untenable under the new pragmatic circumstances. Due to its characteristics, television belongs to the framework of rapid change typical of the dynamics of needs and expectations within the new scale of humankind. There are many varied implications to this: it makes each of us more passive, more and more subject to manipulations (economic, political, religious), robbing (or freeing) us from the satisfaction of a more personal relation (to others, art, literature, etc.). Nobody should underestimate any of these and many other factors discussed by media ecologists and sociologists. But to stubbornly, and quite myopically, consider TV only from the perspective and expectations of literacy is presumptuous. We have to understand the structural changes that made TV and video possible. Moreover, we have to consider the changes they, in turn, brought about. Otherwise we will miss the opportunities opened by the practical experience of understanding the new choices presented to us, and even the new possibilities opened. There is so much more after TV, even on 500 channels and after video-on-demand!

Language is not an absolute democratic medium; literacy, with intrinsic elitist characteristics, even less. Although it was used to ascertain principles of democracy, literacy ended up, again and again, betraying them. Because they are closer to things and actions, and because they require a relatively smaller background of shared knowledge, images are more accessible, although less challenging. But where words and text can obscure the meaning of a message, images can be immediately related to what they refer to. There are more built-in checks in the visual than in the verbal, although the deceptive power of an image can be exploited probably much more than the power of the word. Such, and many other considerations are useful, since the transfer of social and political functions from literacy (books and newspapers, political manifestos, ceremonies and rituals based on writing and reading) to the visual, especially television, requires that we understand the consequences of this transfer. But it is not television that keeps voters away from exercising the right to elect their representatives in the civilization of illiteracy, and not the visual that makes us elect actors, lawyers, peanut farmers, or successful oilmen to the highest (and least useful) posts in the government. Conditions that require the multitude of languages that we use, the layers of mediation, the tendency to decentralization, to name a few, resulted in the increased influence of the visual, as well as in some of the choices mentioned so far.

High definition television (HDTV) helps us distinguish some characteristics of the entire development under discussion-for instance, how the function of integration is carried out. Integration through the intermediary of literacy required shared knowledge, and in particular, knowledge of writing and reading. Integration through the intermediary of modern image-producing technology, especially television and computer-aided visual communication, means access to and sharing of information. Television has made countries which are so different in their identity, history, and culture (as we know the countries of the world to be) seem sometimes so similar that one has to ask how this uniformity came about. Some will point to the influence of the market process- advertisements look much the same all over the world. Others may note the influence of technology-an electronic eye open on the world that renders uniform everything within its range. The new dynamics of human interaction, required by our striving for higher efficiency appropriate to the scale of humankind, probably explains the process better. The similarity is determined by the mechanism we use to achieve this higher efficiency, i.e., progressively deeper labor division, increased mediation, and the need for alternative mechanisms for human integration, that is reflected in TV images. This similarity makes up the substratum of TV images, as well as the substratum of fashion trends, new rituals, and new values, as transitory as all these prove to be.

Literacy and television are not reciprocally exclusive. If this were not the case, the solution to the lower levels of literacy would be at hand. Nevertheless, all those who hoped to increase the quality of literacy by using television had to accept that this was a goal for which the means are not appropriate. Language stabilizes, induces uniformity, depersonalizes; television keeps up with change, allows and invites diversity, makes possible personalized interaction among those connected through a TV chain of cameras and receivers. Literacy is a medium of tedious elaboration and inertia. TV is spontaneous and instantaneous. Moreover, it also supports forms of scientific activity for which language is not at all suited. We cannot send language to look at what our eyes do not see directly, or see only through some instruments. We cannot anticipate, in language, processes which, once made possible on a television screen, make future human experience conceivable. I know that in these last lines I started crossing the border between television and digital image processing, but this is no accident. Indeed, human experience with television, in its various forms and applications, although not at all closed, made necessary the next step towards a language of images which can take advantage of computer technology and of networking.

With the advent of HDTV, television achieves a quality that makes it appropriate for integration in many practical experiences. Design (of clothes, furniture, new products) can result from a collaborative effort of people working at different sites, and in the manufacture of their design during a live session. Modifications are almost instantaneously integrated in the sample. The product can be actually tested, and decisions leading to production made. Communication at such levels of effectiveness is actually integrated in the creative and productive effort. The language is that of the product, a visual reality in progress. The results are design and production cycles much shorter than literacy-based communication can support.

HDTV is television brought to a level of efficiency that only digital formats make possible. The reception of digital television opens the possibility to proceed from each and every image considered appropriate to storing, manipulating, and integrating it in a new context. Digital television reinstates activity, and is subject to creative programming and interactivity. The individual can make up a new universe through the effort of understanding and creative planning. It is quite possible that alternative forms of communication, much richer than those in use today, will emerge from practical experiences of human self-constitution in this new realm. That in ten years all our TV sets, if the TV set remains a distinct receiver, will be digital says much less than the endless creative ideas emerging around the reality of digital television.

Visualization

Whenever people using language try to convince their partner in dialogue, or even themselves, that they understood a description, a concept, a proof, and answer by using the colloquial "I see," they actually express the practical experience of seeing through language. They are overcoming the limitations of the abstract system of phonetic language and returning to the concreteness of seeing the image. Way of speaking equals way of doing-this sums up one of the many premises of this book. We extract information about things and actions from their images. When no image is possible-what does a thought look like, or what is the image of right, of wrong, of ideal?-language supports us in our theoretic experiences, or in the attempt to make the abstract concrete. Language is rather effective in helping us identify kinds of thoughts, in implementing social rules that encode prescriptions for distinguishing between right and wrong, for embodying the just in the institution of justice, and ideals in values. But the experience of language can also be an experience of images.

Once we reach the moment when we can embody the abstract in a concrete theory, in action, in new objects, in institutions, and in choices, and once we are able to form an image of these, share the image, make it part of the visual world we live in, and use it further for many practical or intellectual purposes, we expand the literate experience in new experiences. So it seems that we tend to visualize everything. I would go so far as to say that we not only visualize everything, but also listen to sounds of everything, experience their smell, touch, and taste, and recreate the abstract in the concreteness of our perceptions. The domination of language and the ideal of literacy, which instills this domination as a rule, was and still is seen as the domination of rationality, as though to be literate equals being rational, volens nolens. In fact, the rationality associated with language, and expressed with its help, is only a small part of the potential human rationality. The measure (ratio) we project in our objectification can as well be a measure related to our perceptive system. It is quite plausible to suspect that some of the negative effects of our literate rationality could have been avoided had we been able to simultaneously project our other dimensions in whatever we did.

The shift from a literacy-dominated civilization to the relative domination of the visual takes place under the influence of new tools, further mediations, and integration mechanisms required by self-constitutive practical experiences at the new human scale. The tools we need should allow us to continue exploring horizons at which literacy ceases to be effective, or even significant. The mediations required correspond to complexities for which new languages are structurally more adequate. The necessary integration is only partially achievable through literate means since many people active in the humanities and the sciences gave up the obsession of final explanations and accepted the model of infinite processes.
