CHAPTER XCVII 



POSSIBILITIES 



WHAT, then, are the possibilities? Having ac- 

 quired the required knowledge during the coming 

 half century, possible it is to make such applica- 

 tion of this knowledge during the succeeding half 

 century as to conquer the last invisible foe. Pos- 

 sible it is that in one century from to-day every 

 contagious and infectious disease will be swept 

 from the earth. 



Knowledge will do it. Knowledge does every- 

 thing that is good for the world. Every step in 

 the world's progress is taken by knowledge. Every 

 discovery, every invention is the gift of knowledge. 



Knowledge gave us the alphabet, the multiplica- 

 tion table. Knowledge gave the world the print- 

 ing press, gunpowder, the cotton gin. Knowledge 

 gave the world the locomotive, the telegraph, the 

 telephone. 



To knowledge the world is indebted for all the 

 machinery used in all the industries of modern 

 life. 



First, the knowledge ; then what knowledge does. 

 Such is the Order, and such the Order only, from 

 the brain of the Ape to the brain of Newton.
