主题类文拓展阅读 Unit 1 Science and scientists (选自译林版必修第三册 Unit 4) The Value of Science When I was younger，I thought science would make good things for everybody.It was obviously useful；it was good.But then during the war I worked on the atomic bomb.This result of science was obviously very serious—it represented the destruction of people and it put our future at risk.I had to ask myself，“Is there some evil involved in science？” Put another way，what is the value of the science I had long devoted myself to—the thing I had loved—when I saw what terrible things it could do？It was a question I had to answer.I thought long and hard about this question，and I will try to answer it in this talk. The first way in which science is of value is familiar to everyone：scientific knowledge enables us to do and make all kinds of things.Of course，if we make good things，it is not only to the credit of science；it is also to the credit of the moral choice which led us to good work.Scientific knowledge is an enabling power to do either good or bad—but it does not carry instructions on how to apply it.Such power has obvious value—even though the power may be negated by what one does with it. Another value of science is the intellectual enjoyment it can provide us with.When we look at any question deeply enough，we feel the excitement and mystery coming to us again and again.With more knowledge comes a deeper，more wonderful mystery，inspiring one to look deeper still.Never concerned that the answer may let us down，with pleasure and confidence we turn over each new stone to find unimagined strangeness leading on to more wonderful questions and mysteries.Thanks to the scientific effort，we have been led to imagine all sorts of things more fantastic than poets and dreamers of the past ever could. I would now like to turn to a third value that science has.The scientist has a lot of experience with ignorance and doubt and uncertainty，and this experience is of very great importance.When a scientist doesn’t know the answer to a problem，he is ignorant.When he has an idea as to what the result is，he is uncertain.And when he is pretty sure of what the result is going to be，he is still in some doubt. Now，we scientists take it for granted that it is perfectly possible to live and not know.But our freedom to doubt was born out of a deep and strong struggle against authority in the early days of science.In order to progress，we must not forget the importance of this struggle； we must recognize our ignorance and leave room for doubt.Permit us to question—to doubt—to not be sure. It is our responsibility as scientists，knowing the great progress that is the fruit of freedom of thought，to declare the value of this freedom；to teach how doubt is not to be feared but to be welcomed and discussed；and to demand this freedom as our duty to all coming generations.
