THE CANNIBAL IN EVOLUTION 173 



in evolution, although, judging from the evidence it looks 

 as if changes were more socially structural than cerebral. 

 Yet even now we can say that the best officers in a good 

 modern army belong to a fine order of compact, sufficient 

 intellect. War still requires that equal balance of the 

 body and brain which characterizes them, although they 

 may want some qualities which in themselves are scarcely 

 more than prophetic of possible future race characteristics. 

 It is not necessary to go deeply into cerebral physio- 

 logy or psychology to see that war required the develop- 

 ment of all the main faculties characterizing the human 

 brain. There is no common faculty useful in life which 

 is not necessary to the soldier considered only as such. 

 War is a great intellectual and bodily game, in which the 

 incomplete man goes under. The soldier has to reason, 

 and must reason rapidly, his intuitions must outrun the 

 processes of formal thought. To say so by no means 

 implies that he should be acquainted with the syllogistic 

 skeleton of human reasoning. Men argued in natural 

 moods before scholastic logic, as they still argue without 

 having heard of it. The early warriors organized brain 

 tracts which grasped more and more factors in the en- 

 vironment ; their skill and their salvation depended on 

 new and ready response to new or old stimuli. Such 

 brain faculties are capable of being developed and organized 

 in a measure by hunting, but hunting alone, as we under- 

 stand it, could not have put the last fine edge upon the 

 brain as a weapon, nor would it have eliminated with any 

 rapidity the small-brained races which were incapable 

 of swift variation. Nothing but war would have been 

 so likely to bring out all those qualities which reward 

 skill, quickness, endurance, foresight, and the concentra- 

 tion of endeavour with the crown of victory and the
