As intercommunication tends constantly to widen the field of action of altruism, a point is reached when the individual becomes capable of some kind of sympathy, however attenuated, with beings outside the limits of the biological unit within which the primitive function of altruism lies. This extension is perhaps possible only in man. In a creature like the bee the rigidly limited mental capacity of the individual and the closely organized society of the hive combine to make the boundary of the hive correspond closely with the uttermost limit of the field over which altruism is active. The bee, capable of great sympathy and understanding in regard to her fellow-members of the hive, is utterly callous and without understanding in regard to any creature of external origin and existence. Man, however, with his infinitely greater capacity for assimilating {125} experience, has not been able to maintain the rigid limitation of sympathy to the unit, the boundaries of which tend to acquire a certain indefiniteness not seen in any of the lower gregarious types. Hence tends to appear a sense of international justice, a vague feeling of being responsibly concerned in all human affairs and by a natural consequence the ideas and impulses denoted under the term “pacifism.” One of the most natural and obvious consequences of war is a hardening of the boundaries of the social unit and a retraction of the vague feelings towards international sympathy which are a characteristic product of peace and intercommunication. Thus it comes about that pacifism and internationalism are in great disgrace at the present time; they are regarded as the vapourings of cranky windbags who have inevitably been punctured at the first touch of the sword; they are, our political philosophers tell us, but products of the miasm of sentimental fallacy which tends to be bred in the relaxing atmosphere of peace. Perhaps no general expressions have been more common since the beginning of the war, in the mouths of those who have undertaken our instruction in the meaning of events, than the propositions that pacifism is now finally exploded and shown always to have been nonsense, that war is and always will be an inevitable necessity in human affairs as man is what is called a fighting animal, and that not only is the abolition of war an impossibility, but should the abolition of it unhappily prove to be possible after all and be accomplished, the result could only be degeneration and disaster.
