These works, justly important for the light they shed, and as expressions of a growing sentiment, are eclipsed in the contributions of the great teacher, Immanuel Kant, who, after his fame in philosophy was established, so that his works were discussed and expounded not only throughout Germany, but in other lands, in 1795 crave to the world a treatise entitled "On Perpetual Peace," [Footnote: Zum ewigen Frieden.] which was promptly translated into French, Danish, and Dutch. Two other works by him attest his interest in the subject, the first entitled "Idea for a General History in a Cosmopolitan View," [Footnote: Idee zu einer allgemeinen Geschichte in weltburgerlicher Absicht.] and the other, "Metaphysical Elements of Jurisprudence." [Footnote: Metaphysische Anfangsgrunde der Rechtslehre.] His grasp was complete. A treaty of peace which tacitly acknowledges the right to wage war, as all treaties now do, according to Kant is nothing more than a truce. An individual war may be ended, but not the _state of war_; so that, even after cessation of hostilities, there will be constant fear of their renewal, while the armaments known as Peace Establishments will tend to provoke them. All this should be changed, and nations should form one comprehensive Federation, which, receiving other nations within its fold, will at last embrace the civilized world; and such, in the judgment of Kant, was the irresistible tendency of nations. To a French poet we are indebted for the most suggestive term, "United States of Europe"; [Footnote: Victor Hugo, Discours d'Ouverture du Congres de la Paix a Paris, 21 1849: Treize Discours, (Paris, 1851,) p. 19.] but this is nothing but the Federation of the illustrious German philosopher. Nor was Kant alone among his great contemporaries. That other philosopher, Fichte, whose name at the time was second only to that of Kant, in his "Groundwork of the Law of Nature," [Footnote: Grundlage des Naturrechts.] published in 1796, also urges a Federation of Nations, with an established tribunal to which all should submit. Much better for civilization, had the King at Konigsberg, instead of grasping the sword, hearkened to the voice of Kant, renewed by Fichte. With these German oracles in its support, the cause cannot be put aside. Even in the midst of war, Philosophy will be heard, especially when she speaks words of concurring authority that touch a chord in every heart. Leibnitz, Kant, and Fichte, a mighty triumvirate of intelligence, unite in testimony. As Germany, beyond any other nation, has given to the idea of Organized Peace the warrant of philosophy, it only remains now that she should insist upon its practical application. There should be no delay. Long enough has mankind waited while the river of blood flowed on. UPRISING OF WORKING-MEN.
