CHAPTER VII. 



ANALYSIS OF THE FOUR PRINCIPLES (CONTINUED). 



I. THE METHODS OF THE ENVIRONAL MODE OF EACH PRINCIPLE, WITH THE FORMS 



OF EACH METHOD. 



Producing intensification of habitudinal 



groups: 



Environal election. 

 Endonomic election. 

 Habitudinal election. 

 Aptitudinal election. 

 Heteronomic election. 

 Natural election. 

 Artificial election. 



Producing intensification of racial 



groups: 



Environal selection. 

 Endonomic selection. 

 Habitudinal selection. 

 Aptitudinal selection. 

 Heteronomic selection. 

 Natural selection. 

 Artificial selection. 



Producing demarcation of habitudinal 



groups: 



Environal partition. 

 Endonomic partition. 



Industrial partition. 



Migrational partition. 

 Heteronomic partition. 



Transportational partition. 



Geological partition. 



Artificial partition.

Producing demarcation of racial 



groups: 



Environal isolation. 

 Endonomic isolation. 

 Industrial isolation. 

 Chronal isolation. 

 Seasonal isolation. 

 Cyclical isolation. 

 Migrational isolation. 

 Heteronomic isolation. 



Transportational isolation. 

 Geological isolation. 

 Fertilizational isolation. 

 Artificial isolation. 



Having completed our analysis of the methods and forms of the 

 reflexive mode of influence, we will now briefly survey the forms of the 

 environal mode. Under each or the four principles, when we find that 

 the relations between the group and its environment are determined 

 by conditions within the group, we call the influence endonomic selec- 

 tion, election, isolation, or partition, as the case may be; or if the 

 relations are determined chiefly by conditions lying outside of the 

 group, we then speak of the influence as heteronomic. 



1 . Environal Selection and Environal Election. 



Environal selection, as we have just seen, may be either endonomic 

 or heteronomic. 



Divergent forms of endonomic selection often arise through divergent 

 habitudes or aptitudes of the individuals starting the isolated colonies, or 

 through the accidents attending the entrance of small groups into isolated
