 for mutual advantage, and the Hague Conference is a 

 concrete manifestation of a continuing process of social 

 evolution that finds its beginnings and its interpretation 

 far below human history in lower organic nature. 



But perhaps the most important result of this whole 

 discussion is the lesson of social service that it teaches.

 total life seems far removed from anything going on in 

 an ant-colony, and our daily tasks vary greatly in 

 specific character and degree when compared with those
