As to the sources for the history of the Germany of this period, I have endeavoured to incorporate everything available that seemed to me important for the proper understanding of the time. The three chief general histories of the Reformation, Ranke's _Geschichte Deutschlands während der Reformations-Zeit_, Janssen's _Geschichte des Deutschen Volkes_, and Egelhaaf's _Deutsche Geschichte im sechszehnten Jahrhundert_, have, it is scarcely necessary to say, been laid under contribution. The standpoint of Ranke, whose history is detailed and in certain respects exhaustive, is that of general bourgeois Philistinism. Janssen represents the Ultramontane Catholic view; but, apart from its tendency, every one must admire the brilliant and in most cases accurate scholarship that characterises it. Egelhaaf's work may be regarded as the counterblast to Janssen's. Its point of view is that of "liberal," middle-class German Protestantism; but it also contains many hints and clues which may be followed up by the industrious historian. To rewrite history in the light of the researches of the later decades of the nineteenth century will be the great task of the next two or three generations. History has to be presented afresh on the basis of primitive communism with its tribal and village groups, with its sexual relations based on the _gens_, with its totemistic religious conceptions, and from the standpoint of a continuous development from these beginnings up to the individualism of the present day founded on the complete disruption of early society. The average student of any historical period invariably reads into his interpretation the intellectual, moral and social atmosphere that lies nearest to him. He cannot strip away the intervening time-content between himself and the period in question. It is the most difficult of all exercises of the imagination, and to most men, indeed, impossible, to realise that the same words, names, customs and institutions connote totally different actualities in different stages of historic evolution. People fail to conjure up the altered perspective, and the unfamiliar background on which men lived, thought and felt in another age. Agamemnon, "King of Men," is to them Kaiser Wilhelm differently made up. Lykurgos is a cross between Pitt and Dr. Johnson. Cicero is a Sir Charles Russell who happened to live in the first century B.C. The formal continuity of names, notions or things hides from them the "true inwardness" of the rupture between the old and the new which has gradually accomplished itself. Change in human affairs is of course ceaseless; but it is only when it has reached a certain stage that it is borne in upon the consciousness of men in general, and, even then, it is only the sharp summits above the changing horizon that they recognise. The ground out of which these spring is not seen, and hence the true bearing of the summits themselves is not understood. SOCIAL MOVEMENTS OF THE GERMAN REFORMATION.
