66 UNIVERSAL EVOLUTION 



SOCIAL UNITS. The facts above stated in regard 

 to the advantages to the immigrant, offered by the 

 United States, constitute a variation in forms of 

 society, that is a good illustration of the principle of 

 natural selection, in states and nations. These are 

 social units, and are governed by the same laws of 

 evolution that animal organisms are. Those social 

 units that happen to be organized with a variation, 

 favorable to their struggle for existence, are the ones 

 to survive, and thrive, at the expense of those states,

 constitution is based on the principle that all political 

 power is derived from the people, and there is no state 

 church. Religion is perfectly free, its climate and soil 

 are superior; its agriculture is great. In the struggle
