Why does the idea of progress loom so large in

　　the modern world? Surely because progress of particu-

　　lar kind is actually taking place around us and is more

　　and more manifesting. Although mankind has underg- __1__

　　one no general improvement in intelligence or morali-

　　ty, it has made extraordinary progress in the accumu-

　　lation of knowledge. Knowledge begins to increase as __2__

　　soon as the thoughts of one individual could be com-

　　municated to another by mean of speech. With the in- __3__

　　vention of writing, knowledge could be communicated

　　and stored. Libraries made education possible, and

　　education in turn added libraries: the growth of knowl- __4__

　　edge followed a kind of compound-interest law,

　　which was greatly enhanced by the invention of print-

　　ing. All this was comparatively slow until, with the

　　coming of science, the tempo was suddenly risen. __5__

　　then knowledge began to be accumulated according to

　　a systematic plan. However, as soon as new knowl- __6__

　　edge is acquired, it is now turned to practical ac-

　　count. What is called “modern civilization” is not the

　　result of a balanced development of all man’s nature,

　　but not of accumulated knowledge applied to practical __7__

　　life. The problem now facing humanity is: what is go-

　　ing to be done with all this knowledge? Like is often __8__

　　pointed out, knowledge is a two edged weapon which

　　could be used equally for good or evil. It is now being __9__

　　used indifferently for both. Could any spectacle, for

　　instance, be more grimly whimsical than that gunners __10__

　　using science to shatter men’s bodies while, close at

　　hand, surgeons use it to restore them.
