WE are at the end of our enquiry, but as often happens in the search after truth, if we have answered one question, we have raised many more; if we have followed one track home, we have had to pass by others that opened off it and led, or seemed to lead, to far other goals than the sacred grove at Nemi. Some of these paths we have followed a little way; others, if fortune should be kind, the writer and the reader may one day pursue together. For the present we have journeyed far enough together, and it is time to part. Yet before we do so, we may well ask ourselves whether there is not some more general conclusion, some lesson, if possible, of hope and encouragement, to be drawn from the melancholy record of human error and folly which has engaged our attention in this book.
If then we consider, on the one hand, the essential similarity of man's chief wants everywhere and at all times, and on the other hand, the wide difference between the means he has adopted to satisfy them in different ages, we shall perhaps be disposed to conclude that the movement of the higher thought, so far as we can trace it, has on the whole been from magic through religion to science. In magic man depends on his own strength to meet the difficulties and dangers that beset him on every side. He believes in a certain established order of nature on which he can surely count, and which he can manipulate for his own ends. When he discovers his mistake, when he recognises sadly that both the order of nature which he had assumed and the control which he had believed himself to exercise over it were purely imaginary, he ceases to rely on his own intelligence and his own unaided efforts, and throws himself humbly on the mercy of certain great invisible beings behind the veil of nature, to whom he now ascribes all those far-reaching powers which he once arrogated to himself. Thus in the acuter minds magic is gradually superseded by religion, which explains the succession of natural phenomena as regulated by the will, the passion, or the caprice of spiritual beings like man in kind, though vastly superior to him in power.
But as time goes on this explanation in its turn proves to be unsatisfactory. For it assumes that the succession of natural events is not determined by immutable laws, but is to some extent variable and irregular, and this assumption is not borne out by closer observation. On the contrary, the more we scrutinise that succession the more we are struck by the rigid uniformity, the punctual precision with which, wherever we can follow them, the operations of nature are carried on. Every great advance in knowledge has extended the sphere of order and correspondingly restricted the sphere of apparent disorder in the world, till now we are ready to anticipate that even in regions where chance and confusion appear still to reign, a fuller knowledge would everywhere reduce the seeming chaos to cosmos. Thus the keener minds, still pressing forward to a deeper solution of the mysteries of the universe, come to reject the religious theory of nature as inadequate, and to revert in a measure to the older standpoint of magic by postulating explicitly, what in magic had only been implicitly assumed, to wit, an inflexible regularity in the order of natural events, which, if carefully observed, enables us to foresee their course with certainty and to act accordingly. In short, religion, regarded as an explanation of nature, is displaced by science.
But while science has this much in common with magic that both rest on a faith in order as the underlying principle of all things, readers of this work will hardly need to be reminded that the order presupposed by magic differs widely from that which forms the basis of science. The difference flows naturally from the different modes in which the two orders have been reached.
For whereas the order on which magic reckons is merely an extension, by false analogy, of the order in which ideas present themselves to our minds, the order laid down by science is derived from patient and exact observation of the phenomena themselves. The abundance, the solidity, and the splendour of the results already achieved by science are well fitted to inspire us with a cheerful confidence in the soundness of its method. Here at last, after groping about in the dark for countless ages, man has hit upon a clue to the labyrinth, a golden key that opens many locks in the treasury of nature. It is probably not too much to say that the hope of progressmoral and intellectual as well as materialin the future is bound up with the fortunes of science, and that every obstacle placed in the way of scientific discovery is a wrong to humanity.
