88 The Evolution Hypothesis. 



In an exact use of terms there must be a clear re- 

 coo-nition of this distinction. There is no more

fruitful source of error in philosophizing than the 

 confounding of metaphor and fact. It is unworthy 

 of scientific thinking to group under one term, as the 

 same, things that are only metaphorically alike. 



Does the persisting force include Spirit? There 

 is an underlying something manifested in conscious 

 thought, does the persistence of force guarantee the 

 persistence of that unknown existence ? If force per- 

 sists, then the force manifested in mind persists. But 

 it is hard to comprehend how, on evolution principles, 

 this can be ; for there was a time when all manifested 

 force was included in matter and motion. Mind sub- 

 sequenty arose. The cosmos is represented at two 

 points in time by the following equation : 



Matter + motion = matter + motion +'mind. 



Mind is either a mode of matter and motion or it is 

 not. If it be taken as a mode of matter and motion, 

 we are landed in materialism, which Mr. Spencer re- 

 pudiates. If we choose the other alternative, we are 

 compelled to maintain that a new manifestation of 

 force, not included in the primal manifestations, has 

 emerged, in which case fixedness of the relation be- 

 tween the knowable and the unknowable is rejected. 

 But if one new manifestation has emerged, there is no 

 limit to the modification of the knowable, and the 

 whole fabric of evolution is overturned. Besides, the 

 persistence of force is itself proved to be false, for one
