May I be permitted to enlarge somewhat on this topic? There is, as you are aware, a demand just now for philosophies of History. The general spread of Inductive Science has awakened this appetite; the admirable contemporary French historians have quickened it by feeding it; till, the more order and sequence we find in the facts of the past, the more we wish to find. So it should be (or why was man created a rational being?) and so it is; and the requirements of the more educated are becoming so peremptory, that many thinking men would be ready to say (I should be sorry to endorse their opinion), that if History is not studied according to exact scientific method, it need not be studied at all. A very able anonymous writer has lately expressed this general tendency of modern thought in language so clear and forcible that I must beg leave to quote it:-- 'Step by step,' he says, 'the notion of evolution by law is transforming the whole field of our knowledge and opinion. It is not one order of conception which comes under its influence: but it is the whole sphere of our ideas, and with them the whole system of our action and conduct. Not the physical world alone is now the domain of inductive science, but the moral, the intellectual, and the spiritual are being added to its empire. Two co-ordinate ideas pervade the vision of every thinker, physicist or moralist, philosopher or priest. In the physical and the moral world, in the natural and the human, are ever seen two forces--invariable rule, and continual advance; law and action; order and progress; these two powers working harmoniously together, and the result, inevitable sequence, orderly movement, irresistible growth. In the physical world indeed, order is most prominent to our eyes; in the moral world it is progress, but both exist as truly in the one as in the other. In the scale of nature, as we rise from the inorganic to the organic, the idea of change becomes even more distinct; just as when we rise through the gradations of the moral world, the idea of order becomes more difficult to grasp. It was the last task of the astronomer to show eternal change even in the grand order of our Solar System. It is the crown of philosophy to see immutable law even in the complex action of human life. In the latter, indeed, it is but the first germs which are clear. No rational thinker hopes to discover more than some few primary actions of law, and some approximative theory of growth. Much is dark and contradictory. Numerous theories differing in method and degree are offered; nor do we decide between them. We insist now only upon this, that the principle of development in the moral, as in the physical, has been definitely admitted; and something like a conception of one grand analogy through the whole sphere of knowledge, has almost become a part of popular opinion. Most men shrink from any broad statement of the principle, though all in some special instances adopt it.
