WARFARE IN THE HUMAN

CHAPTER I 

 Method in Science 



THE general method of investigation, suggestion, 

 and proof used in this volume was originally 

 adopted as a means of studying social disorders and dis- 

 eases, for if society is an organism at all, on whatever 

 plane of development, it must be liable to disease, and 

 possess a physiology not remote from that seen at work 

 in other organisms of a lowly type. As the work progressed 

 many side-issues presented themselves, and it was seen that 

 if the notion of developmental diseases in man and other 

 animals had their analogues in society, by which we could 

 learn the nature of, and possible remedies for, social 

 disorders, these should present real analogies with bodily 

 morbid states. Such analogies certainly seemed highly 

 suggestive in the physiology of both kinds of organisms. 

 If, for instance, even the casual study of cerebral physio- 

 logy and neurology threw a light, however dim and un- 

 certain, upon the nature of politics and the methods by 

 which a national organism is directed during normal or 

 abnormal circumstances ; if the nature of the tropisms or 

 instincts of an animal, even of a high type, showed real
