I am not overlooking the case of Germany. Does the history of Germany, during the last half-century, show the blind instinctive pugnacity which is supposed to be so overpowering an element in international relationship as to outweigh all question of material interest? Does the commonly accepted history of the trickery and negotiation which preceded the 1870 conflict, the cool calculation of those who swayed Germany's policy during those years, show that subordination to the blind lust for battle which the militarist would persuade us is always to be an element in our international conflict? Does it not, on the contrary, show that German destinies were swayed by very cool and calculating motives of interest, though interest interpreted in terms of political and economic doctrines which the development of the last thirty years or so has demonstrated to be obsolete? Nor am I overlooking the "Prussian tradition," the fact of a firmly entrenched, aristocratic status, the intellectual legacy of pagan knighthood and Heaven knows what else. But even a Prussian Junker becomes less of an energumen as he becomes more of a scientist,[96] and although German science has of late spent its energies in somewhat arid specialization, the influence of more enlightened conceptions in sociology and statecraft must sooner or later emerge from any thoroughgoing study of political and economic problems. Of course, there are survivals of the old temper, but can it seriously be argued that, when the futility of physical force to accomplish those ends towards which we are all striving is fully demonstrated, we shall go on maintaining war as a sort of theatrical entertainment? Has such a thing ever happened in the past, when our impulses and "sporting" instincts came into conflict with our larger social and economic interests? All this, in other words, involves a great deal more than the mere change in the character of warfare. It involves a fundamental change in our psychological attitude thereto. Not only does it show that on every side, even the military side, conflict must become less impulsive and instinctive, more rational and sustained, less the blind strife of mutually hating men, and more and more the calculated effort to a definite end; but it will affect the very well-springs of much of the present defence of war.
