dom for the good of the race. Among social 

 animals, such as ants and bees, there is so 

 much instinct and so little reason and freedom 

 that there is practically no conflict between 

 the individual and the race, but with the in- 

 crease of intelligence and freedom among men 

 there has developed an increasing conflict be- 

 tween the individual and society. So far as 

 social limitations are artificial, selfish, for the 

 good of a few rather than of all, this conflict of 

 the ages, this struggle to be free has been the 

 crowning glory of mankind. The struggle 

 for freedom from tyranny in thought and 

 speech, in religion, government and industry, 

 no less than for the freedom that comes by 

 the conquest of nature, is one of the greatest 

 achievements of the human race. 



But social restrictions on individual freedom 

 are not all artificial and selfish. Some of them 

 are absolutely essential not only to the welfare 

 but even to the continued existence of the race* 

 and when demands for individual freedom go 

 to the extent of fighting against these racial 

 obligations they become a serious menace to 

 mankind.
