SOME OBLIGATIONS AND OPPORTUNI- 

 TIES OF SCIENTISTS IN THE 

 UPBUILDING OF PEACEi 



We have been free from the ttmnoil of 

 actual warfare for something over a year and 

 it is high time we turn our faces with resolute 

 courage toward the coming years with the 

 determination that the world shall be a 

 happier, saner, and safer one for humanity. 

 The results of victory have probably not been 

 all that we expected and certainly not all that 

 many of us desired while in many respects 

 the results have been entirely unforeseen. To 

 scientists, I imagine, one of the most sur- 

 prising outcomes of the war has been the 

 sudden and I believe permanent enthrone- 

 ment of science in the activities of humanity. 

 In the carrying on and the winning of the 

 war, men of science played an unexpectedly 

 important and indispensable part. The roll 

 of honor among the sciences is large and 

 includes certainly all of them represented 

 here to-night. The men in these sciences 

 were called from every quarter of the nation; 

 and the promptness with which they answered 

 the calls and the effectiveness with which they 

 met the demands made upon them should be 

 a source of pride and profound satisfaction 

 to every one of us. 



THE S-BANDING OF SCIENCE IN THE MINDS OF THB 

 PEOPLE 



As a result of their work the value of re- 

 search and investigation to the welfare of the 

 nation, whether in peace or in war, has taken 

 hold on the minds of the people as never 

 before; and the worth and usefulness of the 

 scientist to humanity have received general 

 recognition from the public to an extent long 

 justified but hardly expected in our day and
