As a romantic teenager, I believed that my future life as a scientist would be justified if I could discover a single new fact and add a brick to the bright temple of human knowledge. The conviction was noble enough; the metaphor was simply silly. Yet that metaphor still governs the attitude of many scientists toward their subject.
72.In the conventional model of scientific "progress ", we begin in superstitious ignorance and move toward final truth by the successive accumulation of facts. In this smug perspective, the history of science contains little more than anecdotal interest--for it can only chronicle past errors and credit the bricklayers for discerning glimpses of final truth. It is as transparent a.s an old-fashioned melodrama: truth (as we perceive it today) is the only arbiter and the world of past scientists is divided into good guys who were right and bad guys who were wrong.
Historians of science have utterly discredited this model during the past decade. Science is not a heartless pursuit of objective information. It is a creative activity, its geniuses acting more as artists than as information processors. Changes in theory are not simply the derivative results of new discoveries but the work of creative imagination influenced by contemporary social and political forces. We should not judge the past through anachronistic spectacles of our own convictions--designating as heroes the scientists whom we judge to be right by criteria that had nothing to do with their own concerns. We are simply foolish if we call Anaximander (sixth century B. C.) an evolutionist because, in advocating a primary role for water among the four elements, he held that life first inhabited the sea; yet most textbooks so credit him.(71)

Edith Smith of New York was concerned about her 18-month-old daughter, Amanda The daughter did not respond when her parents spoke to her, and never react to noises. "She doesn't seem to know what is happening around her," she told the doctor. Without examining Amanda, the doctor assured Edith that her little girl was fine.
But when Amanda was not talking by the time she was two, Edith and her husband became more and more anxious.【1】Finally, Edith took Amanda to an ear, nose and throat specialist, who did an auditory brain-stem response test in which clicking sounds sent through earphones are measured in the brain. This examination showed that Amanda was severely hearing-impaired in both ears. The tragedy was that late detection had delayed her language development and threatened, long-term, to hinder her growth socially.
Hearing impairment is one of the most common birth defects in Asia today.【2】Dr. Andrew Smith, medical officer with the World Health organization's Activities for Prevention of Deafness and Heating Impairment Team in Geneva, Switzerland, estimates that 5.5 million children in Asian-Pacific region are deaf or hearing-impaired. He says that the lack of awareness among parents and some physicians about hearing impairment is a major reason for late detection in children.
Choy Kwee Yuen of Singapore initially did not suspect there was anything wrong with his child. At six month, Choy Jing Xian cooed and gurgled like any other baby. But when Jing Xian was eight months old, Choy became concerned. The infant would sleep through loud noises, including slaps of thunder. His doctor referred the boy to a specialist, who found that Jing Xian had a severe hearing impairment.【3】"All babies up to six months old make vocal noises--it's a natural reflex," says the specialist, "It's hard to distinguish between a three-month-old hearing baby and a three-month-old deaf baby."
He also stresses that even children with moderately severe hearing loss may hear loud sounds or react to hand movements.【4】If a doctor tests a young deaf child's hearing by ringing a bell next to his ear, he may react to the movement of hand rather than the sound. Because hearing problems are often not detected, many children muddle along until hearing screenings are given at school. They don't know they have a problem, and their symptoms may be misinterpreted.
【5】Mounting evidence shows that the longer the delay in diagnosing the problem, the more trouble the child has in developing language and social skills.

Like the population explosion, the scientific and technological revolution began to pick up speed slowly during the eighteenth century. And this ongoing revolution has also suddenly accelerated exponentially. For example, it is now an axiom in n/any fields of science that more new and important discoveries have taken place in the last ten years than in the entire previous history of science. While no single discovery has had the kind of effect on our relationship to the earth that nuclear weapons have had on our relationship to warfare, it is nevertheless tree that taken together, they have completely transformed our cumulative ability to exploit the earth for sustenance——making the consequences of unrestrained exploitation every bit as unthinkable as the consequences of unrestrained nuclear war.
