Physiological psychology adds nothing to 

 mental philosophy. It explains the relation of the 

 nervous system to objective consciousness and Limitations of 

 demonstrates the dependence of the latter upon 

 the former. As a basis of brain building, educa- 

 tion and character forming it is of incalculable 

 value. When applied to its legitimate sphere, too 

 much cannot be said in its favor. But when a 

 physiological psychologist presumes to say that all 

 mental phenomena and psychic power are the 

 product of cerebration, his teachings become not 

 only dangerous, but non-scientific. Prof. James 

 aptly says : "It is obvious that our knowledge of Prof * J ames ' 

 our mental states infinitely exceeds our knowledge 

 of their concomitant cerebral conditions. Our 

 assumption that mind states are absolutely 

 dependent upon brain conditions, must still be 

 understood as a mere postulate. We may have a 

 general faith that it must be true, but any exact 

 insight as to how it is true, lags wo fully behind."
