In the history of the religion of an imperial race, it is not only the development of the ideal within the consciousness of the race itself that we have to consider, but the advance or decline in its conceptions of the religions of the peoples within the zone of its influence or dominion. For such a study the materials are only in appearance less satisfactory than for the study of the political ideal of a race. It is penetratingly observed by La Rochefoucauld that the history of the Fronde can never be accurately written, because the persons in that drama were actuated by motives so base that even in the height of performance each actor of the deeds was striving to make a record of them impossible. The reflection might be extended to other political revolutions, and to other incidents than the Fronde. Ranke's indefatigable zeal, his anxiety “in history always to see the thing as in very deed it enacted itself,” never carried him nearer his object than the impression of an impression. No State papers, no documents, the most authentic, can take us further.

But in this very strife, this zeal for the True, for ever baffled yet for ever renewed, one of the noblest attributes of the present age discovers itself. Indisputable facts are often the sepulchres of thought, and truth after all, not certainty, is the historian's goal.
