COSMIC PHILOSOPHY 



most ferocious tribes are often the most likely 

 to become dominant and assist social integration 

 by subduing other tribes. The earliest annals 

 of the highest of human races, the Aryan, cer- 

 tainly bear witness to extreme ferocity, checked 

 and determined in its direction by a moral sense 

 further developed than that of savages. While 

 recognizing, therefore, the value of Mr. Dar- 

 win's suggestion, so far as it goes, I believe that 

 the true explanation lies much further beneath 

 the surface. 



It will be remembered that, in treating of the 

 parallel evolution of the mind and the nervous 

 system,^ it was shown that the increase of intel- 

 ligence in complexity and speciality involves a 

 lengthening of the period during which the 

 nervous connections involved in ordinary ad- 

 justments are becoming organized. Even if the 

 physical interpretation there given should turn 

 out to be inadequate, the fact remains undeni- 

 able, that while the nervous connections ac- 

 companying a simple intelligence are already 

 organized at birth, the nervous connections ac- 

 companying a complex intelligence are chiefly 

 organized after birth. Thus there arise the 

 phenomena of infancy, which are non-existent 

 among those animals whose psychical actions 

 are purely reflex and instinctive. Infancy, psy- 

 chologically considered, is the period during
