AND PERSONALITY 



individuals may become great successes or great failures. 

 Chance mutation perhaps came their way. 



It was not so many years ago that man lived by piracy, 

 stole his neighbor's pastures, and seized his enemies' wives. 

 We might as well criticize the hunger and thirst that sent 

 the lion forth on his depredations as criticize such a 

 struggling ancestor of long ago. The critics of our forebears 

 judge them as of today. One might as properly criticize 

 them for not having a university degree. 



Obviously morals and behavior are the creatures of the 

 times, not the creators of the times. Mathematics and phys- 

 ics and the forces of gravitation have the same "morals" 

 today as in ancient times, but not history, literature, 

 geography, and religion. These, like morals, change with 

 the times.
