Those participants who were lonelier and more depressed at the start of the two-year study, as determined by a standard questionnaire administered to all subjects, were not more likely to use the Internet. Instead, Internet use itself appeared to cause a decline in psychological well being, the researchers said.

6 Ibid. It seems that lack of physical presence can lead to a kind of moral isolation too. When Larry Froistad confessed to his e-mail support group that he had murdered his daughter, the members of the group offered him sympathy; only one, Ms. De Carlo, felt they should turn him over to the police. See, âOn-Line Thoughts on Off-Line Killingâ by Amy Harmon, The New York Times, April 30, 1998. âIt seemed to Ms. De Carlo that the nature of on-line communication â which creates a psychological as well as physical distance between participants â was causing her friends to forget their off-line responsibilities to bring a confessed murderer to justice.â

ONE THE HYPE ABOUT HYPERLINKS

4 There has been some interesting litigation of late trying to stop this âfree-linkingâ of anything to anything, in which parties have sued others who made links to the plaintiffâs Web page. Of course, this is a fraction of a fraction of a per cent, and is unlikely to have any significant effect on the way the Web is run which has been called a âloose ad-hocracyâ. It no doubt just reflects the dying gasp of the old guard who would like to place at least some limits on the eventual linking of everything to everything.
5 The Dewey decimal system was organized in this way. It did not even allow the same item to be filed under two different categories, but now librarians have more leeway and file the same information under several different headings. For example, Philosophy of Religion would presumably be filed under Philosophy and Religion. Still, however, there is an agreed-upon hierarchical taxonomy.
6 What people now refer to as the modern subject came into being in the early seventeenth century as â thanks to Luther, the printing press, and the new science â people began to think of themselves as self-sufficient individuals. Descartes introduced the idea of the subject as what underlay changing mental states, and Kant argued that, as the objectifier of everything, the subject must be free and autonomous. As we shall see in Chapter 4, SĂžren Kierkegaard concluded that each one of us is a subject called upon to take on a fixed identity that defines who one is and what is meaningful in oneâs world.

17 Indeed, in spite of repeated failures, there is always some new promise on the horizon. The latest company to promise intelligent Web search is Powerset. The current hope is that syntactic natural language processing could at least allow the userâs requests to be made in everyday language and, ideally, also enable the computer to understand the meaning of what is written on each Website. But the problems of capturing embodied common sense knowledge that stalled Lenat for over 20 years have not been solved. They have simply been ignored.

8 Patricia Benner has described this phenomenon in From Novice to Expert: Excellence and Power in Clinical Nursing Practice, Menlo Park, CA, Addison-Wesley, 1984, p. 164. Furthermore, failure to take risks leads to rigidity rather than the flexibility we associate with expertise. When a risk-averse person makes an inappropriate decision and consequently finds himself in trouble, he tries to characterize his mistake by describing a certain class of dangerous situation and then makes a rule to avoid that type of situation in the future. To take an extreme example, if a driver, hastily pulling out of a parking space, is side-swiped by an oncoming car he mistakenly took to be approaching too slowly to be a danger, he may resolve to follow the rule, never pull out if there is a car approaching. Such a rigid response will make for safe driving in a certain class of cases, but it will block further skill refinement. In this case, it will prevent acquiring the skill of flexibly pulling out of parking places. In general, if one follows general rules one will not get beyond competence. Progress is only possible if, responding quite differently, the driver accepts the deeply-felt consequences of his action without detachedly asking himself what went wrong and why. If he does this, he is less likely to pull out too quickly in the future, but...
