It operates through some kind of interface to a user who generates and modifies that information. These are both perfectly valid answers, arising in particular domains to which the theories of computation and electronics are relevant.

If we want to understand a breakdown of the hardware or software, we operate in their terms and turn to them for predictions. But these answers do not deal with what a word processor does-with the fact that it is a medium for the creation and modification of linguistic structures that play a role in human communication.

For the downloadr of a word processor, this is the relevant domain, The word processor exists as a collection of hardware or programs only when it breaks down.. The relevant domain is not a computational one, but one that emerged long ago with the first writing instruments It brings with it concerns of visual presentationissues of layout, type fonts, and integration of text with illustrations.

Many current computer products are designed with a primary concern for this domain.

They deal at length with formats and typography, focussing on the document as the thing being produced But still with this, we have not reached a full understanding of the word processor. We cannot take the activity of writing as an independent phenomenon. Writing is an instrument-a tool we use in our interactions with other people. There is a complex social network in which these activities make sense, It includes institutions such as post offices and publishing compa nies , equipment including word processors and computer networks, but also all of the older technologies with which they coexist , practices such as downloading books and reading the daily mail , and conventions such as the legal status of written documents.

The significance of a new invention lies in how it fits into and changes this network, M any innovations are minor-they simply im prove som e aspect of the network without altering its structure. The automatic transmission made automobiles easier to use, but did not change their role.

Other inventions, such as the computer, are radical innovations that cannot be understood in terms of the previously existing network.

The printing press, the automobile, and television are all examples of radical innovations that opened up whole new domains of possibilities for the network of human interactions. Just as the automobile had impacts on our society far beyond speeding up what had been done with horses, the use of computers will lead to changes far beyond those of a fancy typewriter.

The nature of publishing, the structure of communication within organizations, and the social organization of knowledge will all be altered, as they were with the emergence of other technologies for language, such as the printing press. One might think that the questioning can stop at this point. It is clear and has been widely recognized that one cannot understand a technology without having a functional understanding of how it is used.

Furthermore, that understanding must incorporate a holistic view of the network of technologies and activities into which it fits, rather than treating the technological devices in isolation, But this is still not enough.

W can e say that the word processor must be understood by virtue of the role it plays in communication, the distribution of information, and the accumulation of knowledge. But the innovation in his language had a m ajor impact on human society, in everything from the 1. Looking at computers we find the same process at work. In order to become aware of the effects that computers have on society we must reveal the implicit understanding of human language, thought, and work that serves as a background for developments in computer technology.

In this endeavor we are doubly concerned with language. First, we are studying a technology that operates in a domain of language. The computer is a device for creating, manipulating, and transmitting symbolic hence linguistic objects. Second, in looking at the impact of the computer, we find ourselves thrown back into questions of language-how practice shapes our language and language in turn generates the space of possibilities for action.

This book, then, is permeated by a concern for language. Much of our theory is a theory of language, and our understanding of the computer centers on the role it will play in mediating and facilitating linguistic action as the essential human activity.

In asking what computers can do, we are drawn into asking what people do with them, and in the end into addressing the fundam ental question of what it m eans to be hum an. Every questioning grows out of a tradition-a pre-understanding that opens the space of possible answers. It is not a set of rules or sayings, or something we will find catalogued in an encyclopedia. Even in discussions of what computers can and cannot do, the questions that are posed reflect a particular blindness about the nature of human thought and language-a blindness that can lead to a broad m isunder standing of the role that w be played by com ill puters.

The rationalistic tradition is distinguished by its narrow focus on certain aspects of rationality, which as we will show throughout the book often leads to attitudes and activities that are not rational when viewed in a broader perspective, Our commitment is to developing a new ground for rationality-one that is as rigorous as the rationalistic tradition in its aspirations but that does not share the presuppositions behind it.

The task we have undertaken in this book is to challenge the rationalistic tradition, introducing an alternative orientation that can lead to asking new questions. In developing this new orientation, we were led to a critique of the current mythology of artificial intelligence and its related cognitive theories, drawing conclusions that contradict the naive optimism apparent in the quotations at the beginning of the chapter.

The alternative we pose is not a position in a debate about whether or not computers will be intelligent, but an attempt to create a new understanding of how to design computer tools suited to human use and human purposes. No book can embody the result of such a process, but through entering a dialog with the reader we can help make it possible.

We have attempted to do this in three steps. First we present some previous work that challenges the theoretical assumptions of the rationalistic tradition, calling into question much of what is normally taken for granted in our 1. Next we carefully examine, from the orientation developed in the fi rst part, the phenomena that have emerged in the practice of computer technology Finally, we suggest some alternative directions for the design of computer-based tools.

Part I of the book Chapters describes the rationalistic tradition and presents three distinct bodies of work, each of which stands in contrast to that tradition and each of which has deeply influenced our own understanding.

We do not attempt to provide a philosophical exposition and critique in which arguments for and against each position are enumerated and weighed. We find it more fruitful to present the central points, listening for their relevance to our own concerns. Our discourse is theoretical in that it deals with fundamental questions, but it is not directed towards postulating formal theories that can be systematically used to make predictions.

As will become clear, one of the most prominent illusions of the rationalistic tradition is the belief that knowledge consists of explicit theories of that sort. Chapter 2 describes the rationalistic tradition in some detail, showing how it serves as a basis for our culture's commonsense understanding of language, thought, and rationality.

Our goal is to reveal biases and assumptions that are concealed by their embodiment in the background of our language.. Chapter 3 deals with a tradition that includes hermeneutics the study of interpretation and phenomenology the philosophical examination of the foundations of experience and action. This tradition has emerged from humanistic studies, and is concerned with the relation of the individual to the context-especially the social context-in which he or, she lives.

It emphasizes those areas of human experience where individual interpretation and intuitive understanding as opposed to logical deduction and conscious reflection play a central role.We have attempted to do this in three steps.
