At the cost of some unavoidable tedium, the argument as regards these and similar instances may be summarised. It appears, in the (possibly doubtful) light of the history of democratic institutions and of modern technology hitherto, as also from the logical character of this technology and its underlying material sciences, that consistent addiction to the peculiar habits of thought involved in its carrying on will presently induce a decay of those preconceptions in which dynastic government and national ambitions have their ground. Continued addiction to this modern scheme of industrial life should in time eventuate in a decay of militant nationalism, with a consequent lapse of warlike enterprise. At the same time, popular proficiency in the modern industrial arts, with all that that implies in the way of intelligence and information, is indispensable as a means to any successful warlike enterprise on the modern plan. The menace of warlike aggression from such dynastic States, e.g., as Imperial Germany and Imperial Japan is due to their having acquired a competent use of this modern technology, while they have not yet had time to lose that spirit of dynastic loyalty which they have carried over from an archaic order of things, out of which they have emerged at a very appreciably later period (last half of the nineteenth century) than those democratic peoples whose peace they now menace. As has been said, they have taken over this modern state of the industrial arts without having yet come in for the defects of its qualities. This modern technology, with its underlying material sciences, is a novel factor in the history of human culture, in that addiction to its use conduces to the decay of militant patriotism, at the same time that its employment so greatly enhances the warlike efficiency of even a pacific people, at need, that they can not be seriously molested by any other peoples, however valorous and numerous, who have not a competent use of this technology. A peace at large among the civilised nations, by loss of the militant temper through addiction to this manner of arts of peace, therefore, carries no risk of interruption by an inroad of warlike barbarians,--always provided that those existing archaic peoples who might pass muster as barbarians are brought into line with the pacific nations on a footing of peace and equality. The disparity in point of outlook as between the resulting peace at large by neglect of bootless animosities, on the one hand, and those historic instances of a peaceable civilisation that have been overwhelmed by warlike barbarian invasions, on the other hand, should be evident. * * * * *
