 almost entirely an equipment which comes to the 

 former through the cumulative social inheritance 

 that he receives from civilization. This inheritance

 grasped the immense import of the fact that 

 since man became a serial creature the winning 

 variations upon which Power has rested in his evolu- 

 tion have been to an ever-increasing degree neither 

 variations in the structure of his body nor in the size 

 of his brain, but variations in the type of social culture 

 to which he is being submitted. 



The importance of the principle here emphasized,
