118 SUPER-ORGANIC EVOLUTION 



From what I have said on adaptation, I think I 

 have sufficiently proved that the future of humanity 

 is not subject to the caprice of anyone, but that 

 there exists an irrefragable law which has made 

 man out of a conglomeration of matter, and this 

 same law, sooner or later, will have to be followed, 

 in order that man himself may attain the state of 

 happiness that is his legitimate aspiration. Psychic 

 adaptation would be the best possible corre- 

 spondence between Nature and intelligence. This 

 adaptation would again place man in the right path 

 for the accomplishment of the law of evolution. 



Having explained what has preceded, I can now 

 sum up the facts of psychic life as follows : 



In the lowest beings already appear physical and 

 psychic life, although very slightly differentiated ; 

 but both become capable of differentiation as we 

 ascend the animal scale, until attaining their highest 

 degree of differentiation in man. On his appearance 

 upon the earth, the intelligence, the result of 

 successive psychic adaptations, continues to create 

 fresh series, to amplify those existing, and to 

 associate some with others, in order to give rise to 

 more complex and distinct intellectual complica- 

 tions. The brain has progressed, increasing the 

 number of its neuronas, and, just as the neuronas 

 become distinguished by new powers of perfect- 

 ing themselves which complete a new progress,
