Lesson 22? Knowledge and progress 知识和进步 Why does the idea of progress loom so large in the modern world? Surely because progress of a particular kind is actually taking place around us and is becoming more and more manifest．Although mankind has undergone no general improvement in intelligence or morality, it has made extraordinary progress in the accumulation of knowledge．|| Knowledge began to increase as soon as the thoughts of one individual could be communicated to another by means of speech．With the invention of writing, a great advance was made,for knowledge could then be not only communicated but also stored．Libraries made education possible, and education in its turn added to libraries: the growth of knowledge followed a kind of compound-interest law,which was greatly enhanced by the invention of printing．All this was comparatively slow until, with the coming of science, the tempo was suddenly raised．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 mans 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 mens 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.|| 为什么进步这个概念在现代世界显得如此突出？无疑是因为有一种特殊的进步实际上正在我们周围发生，而且变得越来越明显。虽然人类在智力和道德上没有得到普遍提高，但在知识积累方面却取得了巨大的进步。人一旦能用语言同别人交流思想，知识的积累便开始了。随着书写的发明，又迈进了一大步，因为这样一来，知识不仅能交流，而且能储存了。藏书使
