For ourselves, if it were not the quest of the higher level and the extended horizon, international history would be imposed by the exclusive and insular reason that parliamentary reporting is younger than parliaments. The foreigner has no mystic fabric in his government, and no _arcanum imperii_. For him, the foundations have been laid bare; every motive and function of the mechanism is accounted for as distinctly as the works of a watch. But with our indigenous constitution, not made with hands or written upon paper, but claiming to develope by a law of organic growth; with our disbelief in the virtue of definitions and general principles and our reliance on relative truths, we can have nothing equivalent to the vivid and prolonged debates in which other communities have displayed the inmost secrets of political science to every man who can read. And the discussions of constituent assemblies, at Philadelphia, Versailles and Paris, at Cadiz and Brussels, at Geneva, Frankfort and Berlin, above nearly all, those of the most enlightened States in the American Union, when they have recast their institutions, are paramount in the literature of politics, and proffer treasures which at home we have never enjoyed. [Sidenote: RESOURCES OF MODERN HISTORY] [Sidenote: BEGINNING OF THE DOCUMENTARY AGE] To historians the later part of their enormous subject is precious because it is inexhaustible. It is the best to know because it is the best known and the most explicit. Earlier scenes stand out from a background of obscurity. We soon reach the sphere of hopeless ignorance and unprofitable doubt. But hundreds and even thousands of the moderns have borne testimony against themselves, and may be studied in their private correspondence and sentenced on their own confession. Their deeds are done in the daylight. Every country opens its archives and invites us to penetrate the mysteries of State. When Hallam wrote his chapter on James II., France was the only Power whose reports were available. Rome followed, and the Hague; and then came the stores of the Italian States, and at last the Prussian and the Austrian papers, and partly those of Spain. Where Hallam and Lingard were dependent on Barillon, their successors consult the diplomacy of ten governments. The topics indeed are few on which the resources have been so employed that we can be content with the work done for us, and never wish it to be done over again. Part of the lives of Luther and Frederic, a little of the Thirty Years' War, much of the American Revolution and the French Restoration, the early years of Richelieu and Mazarin, and a few volumes of Mr. Gardiner, show here and there like Pacific islands in the ocean. I should not even venture to claim for Ranke, the real originator of the heroic study of records, and the most prompt and fortunate of European pathfinders, that there is one of his seventy volumes that has not been overtaken and in part surpassed.
