 the simplest orders of evolution, quantitative 

 increase is accompanied by qualitative increase. 

 The knowledge is not only greater and the in- 

 tellectual capacity greater, but the knowledge is 

 more complex, accurate, and unified, and the 

 intellectual capacity is more varied. 



The increase of the correspondence in definite-
