While the novelist has absolute freedom to follow his artistic instinct and intelligence, the biographer is fettered by the subject-matter with which he proposes to deal. The former may hopefully pursue an ideal, the latter must rest satisfied with a compromise between the desirable and the necessary. No doubt, it is possible to thoroughly digest all the requisite material, and then present it in a perfect, beautiful form. But this can only be done at a terrible loss, at a sacrifice of truth and trustworthiness. My guiding principle has been to place before the reader the facts collected by me as well as the conclusions at which I arrived. This will enable him to see the subject in all its bearings, with all its pros and cons, and to draw his own conclusions, should mine not obtain his approval. Unless an author proceeds in this way, the reader never knows how far he may trust him, how far the evidence justifies his judgment. For not to speak of cheats and fools the best informed are apt to make assertions unsupported or insufficiently supported by facts, and the wisest cannot help seeing things through the coloured spectacles of their individuality. The foregoing remarks are intended to explain my method, not to excuse carelessness of literary workmanship. Whatever the defects of the present volumes may be and, no doubt, they are both great and many I have laboured to the full extent of my humble abilities to group and present my material perspicuously, and to avoid diffuseness and rhapsody, those besetting sins of writers on music.
