ORGANIZED KNOWLEDGE AND 

 NATIONAL WELFARE! 



The future of any nation is secure if it 

 lives up to its possibilities. The nation 

 Avhich does this is bound to be a leader 

 among nations and to command world-wide 

 respect. Its national problems will be 

 solved and solved intelligently and thor- 

 oughly. The greatness of a man is in part 

 horn in him and in part the product of his 

 environment. According to eminent biolo- 

 gists, he is about two fifths horn and three 

 fifths made. Similarly, a nation is great 

 according to its resources and according to 

 its development of these resources. And 

 the development of those resources may be 

 accomplished only through organized 

 knowledge. 



I. The Function of Organized Knowl- 

 edge. — Consider for a moment two manu- 

 facturing concerns on an equal footing as 

 regards output, but of which one is con- 

 tinually making progress through improve- 

 ments in manufacturing processes, develop- 

 ing new and valuable products and in- 

 vestigating the fundamental principles 

 underlying all these processes. This firm 

 will in time outstrip the other in every 

 way ; the balance, in fact, is a very delicate 

 one, since the results are cumulative. In 

 quite a similar manner, that nation wiU 

 advance to leadership in which the increase 

 in organized knowledge and the application 

 of that knowledge are greatest. For this 

 reason, interest in research should be as 

 wide as the nation and should cover the
