IN TEEN AT ION AL COOPERATION IN 

 RESEARCH ' 



The intellectual activity of the world, 

 scientific, literary or emotional, passes 

 alternately through fertile and through 

 barren periods. Each fertile period has 

 its characteristic peculiarities and though 

 any one generation may not be competent 

 to form a just estimate of its powers and 

 effects, it is able to compare the fruits of 

 its own labors with the harvest of its pred- 

 ecessors. You will probably agree with me 

 that our age is distinguished by having 

 disclosed a vast array of facts which take 

 us nearer to the infinitesimal structure of 

 matter and which reach further into the 

 infinite design of the universe, than the 

 boldest fiight of imagination could have 

 foreseen half a century ago. But we do 

 not flatter ourselves that the intellect of 

 our time, judged by the power of individ- 

 uals, is exceptionally great. No doubt, 

 men of commanding genius are still with 

 us, but they are not more numerous or 

 more original than in former times. What 

 then is the peculiarity that has produced 

 such great results? In my opinion what 

 has been accomplished is due in great part 

 to the spread of higher education, which 

 has evolved an army of competent investi- 

 gators possessing enthusiasm for research 

 which now, for the first time, is led into 

 useful paths by the few great minds, whose 

 powers thus receive a wider range and be- 

 come more productive. It is in this that 

 our great strength lies.
