Since experiential space and time are housed in our language, we can account for only a three-dimensional space and a homogeneous time that has only one direction-from past to future. Nevertheless, we can conceive of multidimensional spaces and of non-homogeneous time. To describe the same in language, especially through literate expression, is not only inadequate, but also raises obstacles. With the advent of digital technology, a language of two letters-zero and one-and the grammar of Boolean logic, we have stepped into a new age of language, no longer the exclusive domain of the human being. Such a language introduces new levels of mediation, which allow for the use of machines by means of sentences, i.e., sequences of encoded commands triggered by a text written in a language other than natural language. Physical contact is substituted by language, inserted in processes of complexity impossible to control directly or even to relate to in forms characteristic of previous scientific and technological praxis.
Indeed, there are instances when the speed of a process and the requirement of sequencing make direct human control not only impossible, but also undesirable. This mediation is then continued by sequences automatically generated by machines, i.e., mediation generating new mediation. Although the structure of all these new languages (which describe phenomena, support programming, or control processes) is inspired by the structure of natural language, they project experiences which are not possible in the universe of standard language. New forms of interaction, higher speeds, and higher precision become available when such powerful cognitive tools are designed as custom-made instruments for advancing our understanding of phenomena that evade analytic or even small-scale synthetic frameworks.
The discussion of mediation brought up other sign systems that assume the mediating function characteristic of literacy. Not only artificial languages-instruments of knowledge and action, new pragmatic dimensions, in fact-but also natural languages are increasingly used in a mediating capacity. I would submit to the reader the observation that the visual, primarily, and other sensory information are recuperated and used in ways that change human experience. Where words no longer suffice, visualized images of the unseen constitute a mediating language, allowing us to understand phenomena otherwise inaccessible-the micro- or remote universe, for instance. Touch, smell, and sound can be articulated and introduced as statements in a series of events for which written and spoken language are no longer adequate. Virtual reality is synthesized as a valid simulation of real reality. Virtual realities can be experienced if we simply put on body-sensitive gloves, headgear (goggles and earphones), special footwear, or a whole suit. Powerful computer graphics, with a refresh rate high enough to maintain the illusion of space and motion, make a virtual space available. Within this space, one's own image can become a partner of dialogue or confrontation. Journeys outside one's body and inside one's imagination are experienced not only in advanced laboratories, but also in the new entertainment centers that appeal to children as well as adults. Such projections of oneself into something else represent one of the most intriguing forms of interaction in the networked world. The experience of self-constitution as an avatar on the Internet is no longer one of a unique self, but of multiples.
Language guards the entrance to the experience, but once the human subject is inside, it has only limited power or significance. Mediations other than through language dominate here, invoking all our senses and deep levels of our existence, for which literacy produced only psychoanalytic rhetoric. In other words, we notice that while language constituted a projection of the human being in the conventions of abstract systems of expression, representation, and communication, it also exercised an impoverishing function in that it excluded the wealth of senses-possibly including common sense-and the signs addressing them. Language made of us one monolithic entity. In the meantime, we have come to realize that the transitions between our many inner states can be a source of new experiences.
The answer to the question regarding alternatives to literacy is that part of the mediating function of language has extended to specialized languages, and to sign systems other than verbal language, when those systems are better adapted to the complexities of heretofore unencountered challenges. Virtual reality is not a linear reality but an integrating, interacting reality of non-linear relations between what we do and what results. Among these newly acquired, different mediating entities, relations and interdependencies are continuously established and changed at an ever faster pace. It appears that once human activity moves from the predominantly object level to the meta condition (one of self-awareness and self-interpretation), we have several languages and several contingent literacies instead of a dominant language and dominant literacy. When writing is replaced by multimedia along the communication channels of the networked world, we seem to enjoy rediscovering ourselves as much richer entities than we knew or were told about through literate mediation.
The entire transition is the result of pragmatic needs resulting from the fundamental change in continuous human self-constitution and the scale in which it is exercised. Mediations break activities into segments that are more intensive and shorter than the cycle from which they were extracted. Therefore, mediation results in the perception of the reality of faster rhythms and of time contraction. Massive distribution of tasks, finer levels of parallelism, and more sophisticated integrating and coordinating mechanisms, result in new pragmatic possibilities, for which literacy is not suitable, and even counter-productive. This entire transition comprises another vector of change: from individual to communal survival, from direct work to highly mediated praxes, from local to global to universal, from the visible to the invisible of macro and micro-universe, from the real to the virtual. Mediation, in its newest digital forms of enmeshed nature and evolving culture, causes boundaries to disappear between the elements involved in practical experiences of our self-constitution.
Literacy, Language and Market
Markets are mediating machines. In our time, the notion of a machine is very different from that of the industrial Machine Age associated with the pragmatics of the civilization of literacy. Today, the term machine is evocative of software rather than hardware. Machine comprises input and output, process, control mechanisms, and the expectation of predictable functioning. Here is where our difficulties start. At best, markets appear as erratic to us. Market prediction seems to be an oxymoron. Every time experts come up with a formula, the market acts in a totally new manner.
An amazing number of transactions, ranging from bargaining at a garage sale to multi-prong deals in derivatives, continuously subject the outcome of practical experiences of human self-constitution to the test of market efficiency. There is nothing that can escape this test: ideas, products, individuals, art, sports, entertainment. Like a tadpole, the market seems to consume itself in transactions. At times, they appear so esoteric to us that we cannot even fathom what the input of this machine is and what the output. But we all expect the charming prince to emerge from the ugly frog!
What can be said, without giving away the end of the story too early, is that the functioning of this growing mechanism of human self-evaluation could never take place at its current dynamics and size in the pragmatic framework of literacy. All over the world, market processes associated with previous pragmatic frameworks-barter is one of them-are relived in bazaars and shopping malls. But if anyone wants to see practical experiences of the civilization of illiteracy unfolding in their quasi-pure manner, one has only to look at the stock market and commodities exchanges and auctions conducted over the Internet. Moreover, one must try to envision those invisible, distributed, networked transactions in which it is impossible to define who initiated a transaction, continued another one, or brought a deal to an end, and based on what criteria. They, too, seem to have a life of their own.
