To live in the United States today is to gain an appreciation for Dhrendorf's assertion that social change exists everywhere. Technology, the application of knowledge for practical ends, is a major source of social change.
Yet we would do well to remind ourselves that technology is a human creation; it does not exist naturally. A spear or a robot is as much a cultural as a physical object. Until humans use a spear to hunt game—or a robot to produce machine parts, neither is much more than a solid mass of matter. For a bird looking for an object on which to rest, a spear or robot serves the purpose equally well. The explosion of the Challenger space shuttle and the Russian nuclear accident at Chernobyl drive home the human quality of technology; they provide cases in which well-planned systems suddenly went haywire and there was no ready hand to set them right. Since technology is a human creation, we are responsible for what is done with it. Pessimists worry that we will use our technology eventually to blow our world and ourselves to pieces. But they have been saying this for decades, and so far we have managed to survive and even flourish. Whether we will continue to do so in the years ahead remains uncertain. Clearly, the impact of technology on our lives deserves a closer examination.
Few technological developments have had a greater impact on our lives than the computer revolution. Scientists and engineers have designed specialized machines that can do the tasks that once only people could do. There are those who assert that the switch to an information-based economy is in the same camp as other great historical milestones, particularly the Industrial Revolution. Yet when we ask why the Industrial Revolution was a revolution, we find that it was not the machines. The primary reason why it was a revolutionary is that it led to great social change. It gave rise to mass production and, through mass production, to a society in which wealth was not confined to the few.
In somewhat similar fashion, computers promise to revolutionize the structure of American life, particularly as they free the human mind and open new possibilities in knowledge and communication. The Industrial Revolution supplemented and replaced the muscles of humans and animals by mechanical methods. The computer extends this development to supplement and replace some aspects of the mind of human beings by electronic methods It is the capacity of the computer for solving problems and making decisions that represents its greatest potential and that poses the greatest difficulties in predicting the impact on society.

The examples of the Challenger and the Chernobyl are cited in the passage to show that ______.
Should doctors ever lie to benefit their patients—to speed recovery or to conceal the approach of death？ In medicine as in law, government, and other lines of work, the requirements of honesty often seem dwarfed by greater needs: the need to shelter from brutal news or to uphold a promise of secrecy; to expose corruption or to promote the public interest.
What would doctors say, for example, to a 46-year-old man coming in for a routine physical checkup just before going on vacation with his family who, though he feels in perfect health, is found to have a form. of cancer that will cause him to die within six months？ Is it best to tell him the truth？ If he asks, should the doctors deny that he is ill, or minimize the gravity of the illness？ Should they at least conceal the truth until after the family vacation？
Doctors confront such choices often and urgently. At times, they see important reasons to lie for the patient's own sake; in their eyes, such lies differ sharply from self-serving ones.
Studies show that most doctors sincerely believe that the seriously ill do not want to know the truth about their condition, and that informing them risks destroying their hope, so that they may recover more slowly, or deteriorate faster, perhaps even commit suicide, As one physician wrote: "ours is a profession which traditionally has been guided by a precept that transcends the virtue of uttering the truth for truth's sake, and that is as for as possible do harm."
Armed with such precept, a number of doctors my slip into deceptive practices that they assume will "do no harm" and may will help their patients. They may prescribe innumerable placebos, sound more encouraging than the facts warrant, and distort grave news, especially to the incurably ill and the dying.
But the illusory nature of the benefits such deception is meant to produce is now coming to be documented. Studies show that, contrary to the belief of many physicians, an overwhelming majority of patients do want to be told the truth, even about grave illness, and feel betrayed when they learn that they have been misled. We are also learning that truthful information, humanely conveyed, helps patients cope with illness: helps them tolerate pain better, need less medicine, and even recover faster after surgery.
Not only do lies not provide the "help" hoped for by advocates of benevolent deception; they invade the autonomy of patients and render them unable to make informed choices concerning their own health, including the choice of whether to be a patient in the first place. We are becoming increasingly aware of all that can befall patients in the course of their illness when information is denied or distorted.
Dying patients especially—who are easiest to mislead and most often kept in the dark—can then not make decision about the end of life: about whether or not they should enter a hospital, or have surgery; about where and with whom they should spend their remaining time; about how they should bring their affairs to close and take leave.
Lies also do harm to those who tell them: harm to their integrity and, in the long run, to their credibility. Lies hurt their colleagues as well. The suspicion of deceit undercuts the work of the many doctors who are scrupulously honest with their patients; it contributes to the spiral of lawsuits and of "defensive medicine," and thus it injure, in turn, the entire medical profession.
Sharp conflicts are now arising. Patients are learning to press for answers. Patients' bills of rights require that they be informed about their condition and about alternatives for treatment. Many doctors go to great eloquent bill of rights, believers in benevolent deception continue their age-old practices. Colleagues may disapprove but refrain from objecting. Nurses may bitterly resent having to take part, day after day, in deceiving patients, but feel powerless to ta
