THE ORGANIZATION OF 



KNOWLEDGE 



11 



The aim of all organized knowledge is to in- 

 crease the certainty of prediction, or as a 

 practical question the science of forecasting, 

 the urgency of which was never more apparent 

 than it is to-day. As has been said by Jevons, 

 "With the progress of any branch of science 

 the element of chance becomes much reduced," 

 for "Not only are laws discovered which en- 

 able results to be predicted . . . but the 

 systematic examination of phenomena and sub- 

 stances leads to important and novel discoveries 

 which can in no sense be said to be accidental." 

 The application of this principle to the science 

 of human relations is obvious, yet rarely recog- 

 nized with the required degree of clearness. 

 A vast amount of human activity continues 

 to be carried on, crude as it may be, in dis- 

 regard of past experience but of necessity as 

 an adventure or speculation, the evil results 

 of which are most likely to fall upon others 

 than those directly concerned. It is not only
