Those words were written exactly one hundred and ten years ago, and the world is once more anxiously looking forward to another Jena which will deal a final blow to the Hohenzollern monarchy. When that catastrophe comes, Europe, enlightened by the awful experiences of the last hundred years, and delivered from the black magic of the political necromancers of Potsdam, will unanimously echo the prophetic judgment pronounced by Joseph de Maistre. For to-day, even more than in 1807, Prussia has become an “argument against Providence.” Even more than in 1807 the Prussia of 1917 “is built with blood and mud.” Even more than in 1807 the chastisement of Prussia is demanded by “eternal justice.” The whole civilized world will breathe more freely when the sinister and diabolical power will be broken for ever and will oppress and degrade humanity no more. CHAPTER IV THE GERMAN WAR-TRIUMVIRATE I.—NIETZSCHE. The English reader is now in possession of a complete translation of Nietzsche, in the admirable edition published by T. N. Foulis, and edited by Oscar Levy, of which the eighteenth and concluding volume has just appeared. To the uninitiated I would recommend as an introductory study: (1) Professor Lichtenberger’s volume; (2) Ludovici, “Nietzsche” (1s., Constable), with a suggestive preface by Dr. Levy; (3) the very useful summary of Mr. Mügge—an excellent number in an excellent series (Messrs. Jack’s “People’s Books”); (4) Dr. Barry’s chapter in the “Heralds of Revolt,” giving the Catholic point of view; (5) Mrs. Förster-Nietzsche, “The Young Nietzsche”; and (6) an essay by the present writer, published as far back as 1897, and which, therefore, may at least claim the distinction of having been one of the first to draw attention in Great Britain to the great German writer. But a searching estimate of Nietzsche in English still remains to be written. And there is only one man that could write it, and that man is Mr. Gilbert K. Chesterton. I confidently prophesy that a study of Nietzsche, if he has the courage to undertake it, will be Mr. Chesterton’s greatest book. He will find in the German heretic a foe worthy of his steel. I.
