[76] Reason requires a State of nations. This is the ideal, and Kant’s proposal of a federation of states is a practical substitute from which we may work to higher things. Kant, like Fichte, (_Werke_, VII. 467) strongly disapproves of a universal monarchy such as that of which Dante dreamed—a modern Roman Empire. The force of necessity, he says, will bring nations at last to become members of a cosmopolitan state, “or if such a state of universal peace proves (as has often been the case with too great states) a greater danger to freedom from another point of view, in that it introduces despotism of the most terrible kind, then this same necessity must compel the nations to enter a state which indeed has the form not of a cosmopolitan commonwealth under one sovereign, but of a federation regulated by legal principles determined by a common code of international law.” (_Das mag in d. Theorie richtig sein_, _Werke_, (Rosenkranz) VII., p. 225). Cf. also _Theory of Ethics_, (Abbott), p. 341, _note_; _Perpetual Peace_, pp. 155, 156. This scheme of a perpetual peace had not escaped ridicule in the eighteenth century: the name of Kant protected it henceforth. The facts of history, even more conclusively than the voices of philosophers, soldiers and princes, show how great has been the progress of this idea in recent years. But it has not gained its present hold upon the popular mind without great and lasting opposition. Indeed we have here what must still be regarded as a controversial question. There have been, and are still, men who regard perpetual peace as a state of things as undesirable as it is unattainable. For such persons, war is a necessity of our civilisation: it is impossible that it should ever cease to exist. All that we can do, and there is no harm, nor any contradiction in the attempt, is to make wars shorter, fewer and more humane: the whole question, beyond this, is without practical significance. Others, on the other hand,—and these perhaps more thoughtful—regard war as hostile to culture, an evil of the worst kind, although a necessary evil. In peace, for them, lies the true ideal of humanity, although in any perfect form this cannot be realised in the near future. The extreme forms of these views are to be sought in what has been called in Germany “the philosophy of the barracks” which comes forward with a glorification of war for its own sake, and in the attitude of modern Peace Societies which denounce all war wholesale, without respect of causes or conditions. _Hegel, Schiller and Moltke._
