Lesson 22-2 Knowledge and progress 知识和进步
Then knowledge began to be accumulated according to a systematic plan．The trickle became a stream; the stream has now become a torrent．|| Moreover, as soon as new knowledge is acquired, it is now turned to practical account．What is called‘ modern civilization’ is not the result of a balanced development of all man's nature, but of accumulated knowledge applied to practical life．The problem now facing humanity is: What is going to be done with all this knowledge? As is so often pointed out, knowledge is a two-edged weapon which can be used equally for good or evil．It is now being used indifferently for both．Could any spectacle, for instance, be more grimly whimsical than that of gunners using science to shatter men's bodies while, close at hand, surgeons use it to restore them? We have to ask ourselves very seriously what will happen if this twofold use of knowledge, with its ever-increasing power, continues.
