If Poetry must not theorise, much less should the historian theorise, whose obligations to be true to fact are even greater than the poet's. If the drama is grandest when the action is least explicable by laws, because then it best resembles life, then history will be grandest also under the same conditions. 'Macbeth,' were it literally true, would be perfect history; and so far as the historian can approach to that kind of model, so far as he can let his story tell itself in the deeds and words of those who act it out, so far is he most successful. His work is no longer the vapour of his own brain, which a breath will scatter; it is the thing itself, which will have interest for all time. A thousand theories may be formed about it--spiritual theories, Pantheistic theories, cause and effect theories; but each age will have its own philosophy of history, and all these in turn will fail and die. Hegel falls out of date, Schlegel falls out of date, and Comte in good time will fall out of date; the thought about the thing must change as we change; but the thing itself can never change; and a history is durable or perishable as it contains more or least of the writer's own speculations. The splendid intellect of Gibbon for the most part kept him true to the right course in this; yet the philosophical chapters for which he has been most admired or censured may hereafter be thought the least interesting in his work. The time has been when they would not have been comprehended: the time may come when they will seem commonplace. It may be said, that in requiring history to be written like a drama, we require an impossibility. For history to be written with the complete form of a drama, doubtless is impossible; but there are periods, and these the periods, for the most part, of greatest interest to mankind, the history of which may be so written that the actors shall reveal their characters in their own words; where mind can be seen matched against mind, and the great passions of the epoch not simply be described as existing, but be exhibited at their white heat in the souls and hearts possessed by them. There are all the elements of drama--drama of the highest order--where the huge forces of the times are as the Grecian destiny, and the power of the man is seen either stemming the stream till it overwhelms him, or ruling while he seems to yield to it. It is Nature's drama--not Shakespeare's--but a drama none the less.
