50 SUPER-ORGANIC EVOLUTION 



the cerebral instrument, in the same way as an 

 artist draws from his instrument the notes of the 

 melodious creation of his genius. Nature and 

 the artist make the marvellous rhythms of the 

 universal harmony vibrate in the brain or the 

 instrument. 



The relation of the intelligence with Nature is so 

 intimate and close that we say that the one is the 

 property of the other, seeing that the intelligence 

 is a function of Nature, and there exists the same 

 unity between them as between organ and function. 

 Strictly speaking, property does not exist, given 

 that man and Nature are the same thing. Now 

 that science has shown the perfect harmony and 

 dependence of all forces, man, the result of those 

 same energies, cannot live outside the natural laws 

 as he does in the actual social organisation, but he 

 has to follow the function of Nature within evolu- 

 tion, and he thus follows the development to w^hich 

 it points. 



Let us stop a moment here to recapitulate and 

 deduce, from all that has been said and set forth in 

 the study of the illustrations, what is the mechanism 

 by means of which the configuration of the neurona 

 develops itself and facilitates its evolution up to 

 the human brain itself. 



As we gather from the monistic theory, embry-
