FIRST LAWS OF SCIENCE OF POWER 187 



As a matter of fact, both formulae are lacking in an 

 essential element. The axiom or law of progress 

 which supplies what is missing in Darwin's con- 

 ception and which expresses the characteristic 

 meaning of integration in life so as to bring 

 that meaning into line with the principles set 

 out in Book I. of Newton's Principia must be 

 put as follows : 



II. Integration in life follows the line of maxi- 

 mum Power. 



The principle of the survival of the fittest or 

 natural selection coming to us from Darwin and 

 Spencer is, it will be observed, a less complete ex- 

 pression of this law of maximum Power. 



The feature of life is its two phases of integration 

 governed by quite different applications of the law 

 of maximum Power. First, there is the Individual 

 Integration. It was practically with the Individua 1 

 Integration alone that Darwin was concerned. His 

 conception did not in any real sense extend to the 

 higher or Social Integration. The distinctive 

 governing principle of each of these two phases of 

 evolution may be set out as follows : 



VI. In the Individual Integration evolution 

 follows the line of maximum Power through 

 the self-assertion of the individual. The 

 centre of gravity in the process is in the
