STUDY OF BRAIXS OF SIX EMINENT SCIENTISTS AND SCHOLARS. 



the classification above adopted to be one meeting all the requisites involved. The 

 simple division into representatives of science, creative arts and action is necessitated 

 by the smallness of numbers ; a proper rubrication would leave more than one im- 

 portant division represented by only one or two individuals. Aside from the failure 

 of three groups to provide for the various branches of mental activity as manifested 

 in various professions — here conventionally adopted — it were doubtful if mature

reflection would endorse such classification. The latter is far from a natural one, for it 

 does not regard the intrinsic physiological relations of the professions, arts and sciences. 

 For example, the sharp demarcation of art and science leaves music and mathematics 

 abruptly and remotely separated ; yet, whatever justifiable presumption exists as to the 

 relations of cortical fields would assign both to closely situated, nay, in almost identi- 

 cal areas, tracts, and neurones of such. Again, to place, for example, generals in one 

 group, is to throw in a chaos of unrelated units the mathematical genius, the geo- 

 graphical explorer, the expert physicist with the strategic adventurer and opportune 

 gambler of the battlefield chess-board. 



With these limitations the following table expresses the results of such classifica- 

 tions in condensed form :
