CHAPTER XIX. 



ILLUSTRATIONS AND CRITICISMS. 



THE discussion contained in the foregoing chapter has shown 

 to what a notable extent the phenomena of social evolution 

 may be expressed, with the strictest accuracy, by formulas 

 originally invented to describe the evoluti &amp;gt;n of life in 

 general. Let us briefly review the results ^liich we have 

 already obtained. 



First, we saw that social as well as orgajfc evolution 

 consists in the continuous adaptation of the community, or 

 organism, to the environment. Or, expressing the &quot;same thing 

 in other words, social progress is a continuous establishment 

 of inner relations in conformity to outer relations. 



Secondly, we saw that in the course of this adrptation 

 the community, like the organism, continually increases in 

 definite heterogeneity, through successive differentiations and 

 integrations. 



Thirdly, vre saw that in the community, as in the organism, 

 the increase in internal heterogeneity is determined by the 

 continuous increase of heterogeneity in the environment. 



Fourthly, we saw that the increase of heterogeneity in the 

 environment is determined by the successive integration of 

 communities into more and more complex and coherent 

 aggregates. And this law also holds of organic progress.
