32 SUPER-ORGANIC EVOLUTION 



A change of colour in the light suffices for the 

 modification of all under its influence according to 

 its genus of movement ; red and blue have entirely 

 different caloric or chemical effects. The experi- 

 ments of putting plants during their development 

 under the influence of different colours are well 

 known, the same species showing completely 

 different results under the different conditions. 



Matter obeys force everywhere ; every form obeys 

 some special mode of movement or systems of 

 movement so much so that one can say: "The 

 form is the result of a system of forces." 



The cell, the biological unity which can be 

 considered as the point of departure of the organic 

 world, is subject to the infinite variety of the 

 rhythmic movements, for which it has a marvellous 

 affinity, and these rhythms of an infinite poten- 

 tiality go on permeating the organic substance and 

 evolving harmonies more and more complex, until 

 it arrives at the representation of man in the actual 

 moment of evolution. 



Man is a product of natural forces, and so much 

 does he depend on them that life without them 

 would be impossible. 



Man is the result of the woof formed by the 

 different rhythms of Nature, as the figures in a 

 tapestry are the outcome of the blending of threads
