For according to socialist doctrine the great events of the world are determined by economic factors. The idealists may speak of national honor and national duty, of the inviolability of treaties and the sacred rights of small nations, but the cause of all wars is really to be traced to the clash of economic motives. If we are to establish peace, we must found it on the customary reactions of selfish men, who want things and are willing to fight for them. Peace must be a peace between men as they are. It will not come by preaching, nor by nations surrendering their ambitions. It will not come through non-resistance, through the submission of the meek to the overbearing. It will not come through the nations joyously disarming as the light of reason breaks through the clouds. Reason is not so simple nor so unrelated a thing, for the material things that each nation wants, and the means by which the nation gets them, seem to the nation preeminently just and reasonable. However pompous the superstructure of ethics and ideals, the solid foundation of war, as of other social developments, is economic. So long as nations, or at all events their ruling groups, have conflicting economic interests, war is inevitable. According to the Socialist, therefore, war and capitalism were inseparable. War must continue so long as the wage-system continued. The argument was simple. The great owners of capital, earning more than they could consume or profitably invest in home industries, were compelled to send their surplus to colonies and dependencies, where a new profit could be made. With the rapid increase of capital, however, the competition between the industrial nations for the possession of these agricultural dependencies became keener. Such competition meant war. As capitalism approached its climax wars were bound to become more frequent, destructive, and violent. [Sidenote: But now competitive imperialism makes way for imperialism by combination.]
