This result of science was obviously very serious-it represented the destruction of people of and it put our future at risk. I had to ask myself, “Is there some
2、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? I thought long and hard about this question, and I will try to answer it today. The first way in which science is of value is f
3、amiliar 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
4、bad-but it doe snot carry instructions on how to apply it. Such power has obvious value; however, the power is decided by what one does. Another value of science is the intellectual enjoyment it can provide us with. When we look at any problem deeply enough, we feel the excitement and mystery coming
5、 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
6、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 t
7、his experience is of great importance. When a scientist doesnt 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
8、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 uncerta
9、inty. Permit us to question, to bout, to be unsure. 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 ensure this freedom fo
