But, above all things, the historian must get out of his own age into the time in which he is writing. Imagination is as much needed for the historian as the poet. You may combine bits of books with other bits of books, and so make some new combinations, and this may be done accurately, and, in general, much of the subordinate preparation for history may be accomplished without any great effort of imagination. But to write history in any large sense of the words, you must be able to comprehend other times. You must know that there is a right and wrong which is not your right and wrong, but yet stands upon the right and wrong of all ages and all hearts. You must also appreciate the outward life and colours of the period you write about. Try to think how the men you are telling of would have spent a day, what were their leading ideas, what they cared about. Grasp the body of the time, and give it to us. If not, and these men could look at your history, they would say, “This is all very well; we daresay some of these things did happen; but we were not thinking of these things all day long. It does not represent us.”
After enlarging upon this great requisite, imagination, it seems somewhat prosaic to come down to saying that history requires accuracy. But I think I hear the sighs, and sounds more harsh than sighing, of those who have ever investigated anything, and found by dire experience the deplorable inaccuracy which prevails in the world. And, therefore, I would say to the historian almost as the first suggestion, “Be accurate; do not make false references, do not mis-state: and men, if they get no light from you, will not execrate you. You will not stand in the way, and have to be explained and got rid of.”
Another most important matter in writing history, and that indeed in which the art lies, is the method of narrating. This is a thing almost beyond rules, like the actual execution in music or painting. A man might have fairness, accuracy, an insight into other times, great knowledge of facts, some power even of arranging them, and yet make a narrative out of it all, so protracted here, so huddled together there, the purpose so buried or confused, that men would agree to acknowledge the merit of the book and leave it unread. There must be a natural line of associations for the narrative to run along. The separate threads of the narrative must be treated separately, and yet the subject not be dealt with sectionally, for that is not the way in which the things occurred. The historian must, therefore, beware that those divisions of the subject which he makes for our ease and convenience, do not induce him to treat his subject in a flimsy manner. He must not make his story easy where it is not so.
