The Evolution of Mind. 215 



" Psychology is a totally unique science, independent 

 of and antithetically opposed to all other sciences 

 whatever. The thoughts and feelings which consti- 

 tute a consciousness, and are absolutely unanswerable 

 to any but the possessor of that consciousness, form 

 an existence that has no place among the existences 

 with which the rest of the sciences deal. Though 

 accumulated observations and experiments have led 

 us by a very indirect series of inferences to the belief 

 that mind and nervous action are the subjective and 

 objective faces of the same things, we remain utterly 

 incapable of seeing and even imagining how the two 

 are related. Mind still continues to us a something 

 without any kinship to other things ; and from the 

 science which discloses by introspection the laws of 

 this something, there is no passage by transitional 

 steps to the sciences which discover the laws of these 

 other things." * 



Evolutionism has, at this point, reached a demarca- 

 tion so clear and deep that it would appear hopeless 

 to attempt to combine in one the two classes of facts. 

 But if they cannot be brought into one coherent 

 organic whole, the unification of knowledge is still 

 incomplete; the principle of continuity is violated

 realms ; dynamic principles do not rule all experience ; 

 the totality of concrete existences cannot be made to
