28 NO DIFFERENTIATION OF NERVE-CELLS. 



observed, in reply to this statement, through which 

 his high intelligence is manifested, have no known 

 prototype or rudimentary representatives in the 

 lower animals ; and as nothing can come of nothing, 

 so it is impossible to admit that the human brain 

 could ever have been evolved in the course of any 

 number of generations from that of an ape or other 

 brute, in which there is no manifestation of anything 

 like human mind even in the most rudimentary 

 degree. 



In regard to cells generally, it is important to 

 remember a fundamental principle in their biology 

 a fundamental principle overlooked by Evolutionists, 

 viz., that they are of various kinds, each kind 

 possessing its own peculiar vital endowments, and 

 its own mode of further development. One kind of 

 cells cannot give origin to another kind of different 

 endowments. There is no such thing as ( differenti- 

 ation/ in the sense in which Evolutionists employ the 

 term. As, therefore, the cells from which the optic 

 nerve, for example, is developed cannot be developed 

 into the auditory nerve, nor the cells from which the 

 auditory nerve is developed, into the optic nerve ; 

 moreover, as the optic nerve cannot perform the 

 function of the auditory nerve, nor this the function 

 of that ; so, as none of the brain-cells of an ape can 

 perform functions like those performed by the pecu- 

 liar cells of the human brain, through which man's 

 high intelligence is specially manifested, there is no 

 reason to believe that any of the brain- cells such as
