Happily, this does not mean that former work has been lost. I have not been trying the patience of my readers by a repetition of well-known views without some cogent reasons. The subject is far too wide and important to admit of a brilliantly unexpected solution by one mind or even one generation of workers. A superficial observer may be so much struck by the variations and contradictions, that he will fail to realise the intimate dependence of every new investigator on his predecessors. 'The subjective side of history,' as the Germans would say, has been noticed before now and the taunt has been administered with great force: 'Was Ihr den Geist der Zeiten heisst, das ist im Grund der Herren eigener Geist, in dem die Zeiten sich bespiegeln.' Those who do not care to fall a prey to Faust's scepticism, will easily perceive that individual peculiarities and political or national pretensions will not account for the whole of the process. Their action is powerful indeed: the wish to put one's own stamp on a theory and the reaction of present life on the past are mighty incitements to work. But new schools do not rise in order to pull down everything that has been raised by former schools, new theories always absorb old notions both in treatment of details and in the construction of the whole. We may try, as conclusion of our review of historical literature, to notice the permanent gains of consecutive generations in the forward movement of our studies. The progress will strike us, not only if we compare the state of learning at both ends of the development, but even if we take up the links of the chain one by one. The greatest scholars of the time before the French Revolution failed in two important respects: they were not sufficiently aware of the differences between epochs; they were too ready with explanations drawn from conscious plans and arrangements. The shock of Revolution and Reaction taught people to look deeper for the laws of the social and political organism. The material for study was not exactly enlarged, but instead of being thrown together without discrimination, it was sifted and tried. Preliminary criticism came in as an improvement in method and led at once to important results. Speaking broadly, the field of conscious change was narrowed, the field of organic development and unconscious tradition widened. On this basis Savigny's school demonstrated the influence of Roman civilisation in the Middle Ages, started the inquiry as to national characteristics, and shifted the attention of historians from the play of events on the surface to the great moral and intellectual currents which direct the stream. Palgrave's book bears the mark of all these ideas, and it may be noticed especially that his chief effort was to give a proper background to English history by throwing light on the abiding institutions of the law.
