which might have been of great value.
It seems remarkable that among gregarious animals other than man direct conflict between major units such as can lead to the suppression of the less powerful is an inconspicuous phenomenon. They are, it may be supposed, too busily engaged in maintaining themselves against external enemies to have any opportunities for fighting within the species. Man’s complete conquest of the grosser enemies of his race has allowed him leisure for turning his restless pugnacity—a quality no longer fully occupied upon his non-human environment—against his own species. When the major units of humanity were small the results of such conflict were not perhaps very serious to the race as a whole, except in prolonging the twilight stages of civilization. It can scarcely be questioned that the organization of a people for war tends to encourage unduly a type of individual who is abnormally insensitive to doubt, to curiosity, and to the development of original thought. With the enlargement of the unit and the accompanying increase in knowledge and resources, war becomes much more seriously expensive to the race. In the present war the immense size of the units engaged and their comparative equality in power have furnished a complete reductio ad absurdum of the proposition that war in itself is a good thing even for the individual nation. It would seem, then, that in the original proposition the word “war” must be qualified to mean a war against a smaller and notably weaker adversary. The German Empire was founded on such wars. {131} The conception of the biological necessity of war may fairly be expected to demonstrate its validity in the fate of that Empire if such a demonstration is ever to be possible. Every condition for a crucial experiment was present: a brilliant inauguration in the very atmosphere of military triumph, a conscious realization of the value of the martial spirit, a determination to keep the warrior ideal conspicuously foremost with a people singularly able and willing to accept it. If this is the way in which an ultimate world-power is to be founded and maintained, no single necessary factor is
