up to the discovery of the central entity, the real Self, 

 one and indivisible. 



These two modes of regarding the individual remain 

 the same, under whatever mode, monist or pluralist, 

 we may regard things at large. 



The former concept has in its favour, simplicity 

 and the methodological principle of economy of causation. 



Against it there is the diversity between physio- 

 logical and psychological facts, and the insurmountable 

 difficulty of subordinating the latter to the former; and, 

 more especially, its flagrant insufficiency in explaining, 

 not merely psychic activity, but even vital activity. 



Methodical analysis of the classical concepts of 

 physiological and psychological individuality will bring 

 this out.
