"In the Esplanade des Invalides, amidst exotic and colonial buildings, one structure of a more severe style rises in the picturesque bazaar; all these representatives of the terrestrial globe adjoin the Palace of War. A superb subject of antitheses for humanitarian rhetorics! Indeed, it does not let pass an occasion for deploring such juxtaposition and for asserting that this will kill that (_ceci tuera cela_),[12] that the union of the nations through science and labour will conquer the martial instincts. We shall not keep it from fondling the hope of the chimera of a golden age, which, if it should be realized, would soon become an age of mire. All history teaches us that blood is needed to speed and confirm the union of the nations. The natural sciences have in our time confirmed the mysterious law which was revealed to Joseph de Maistre by the inspiration of his genius and the consideration of primitive dogmas; he saw how the world redeems its hereditary falls by a sacrifice; the sciences show us how the world is perfected by struggle and by compulsory selection; this is the assertion from two sides of the same decree, written out in different expressions. The assertion is naturally not a pleasant one; but the laws of the world are not established for our pleasure,--they are established for our perfection. Let us, then, enter into this unavoidable, indispensable Palace of War; and we shall have occasion to observe in what manner the most stubborn of our instincts, without losing anything of its force, is transformed, in submitting to the different demands of historic moments." [12] Words from Victor Hugo's novel, _Notre Dame_, in regard to printing, which will kill architecture.--_Author's Note._ This idea, that the proof of the necessity of war is to be found in two expressions of Maistre and Darwin, two great thinkers according to his opinion, pleases Vogüé so much that he repeats it. "Dear Sir," he writes to the editor of the _Revue des Revues:_ "You ask for my opinion in regard to the success of the Universal Congress of Peace. I believe, with Darwin, that a violent struggle is a law of Nature, by which all beings are ruled.
