But, fortunately, we are spared all discussion on this worn subject, for two cogent reasons. For one thing, we do not demand of Nature directly to prove Religion. That was never its function. Its function is to interpret. And this, after all, is possibly the most fruitful proof. The best proof of a thing is that we _see_ it; if we do not see it, perhaps proof will not convince us of it. It is the want of the discerning faculty, the clairvoyant power of seeing the eternal in the temporal, rather than the failure of the reason, that begets the sceptic. But secondly, and more particularly, a significant circumstance has to be taken into account, which, though it will appear more clearly afterward, may be stated here at once. The position we have been led to take up is not that the Spiritual Laws are analogous to the Natural Laws, but that _they are the same Laws_. It is not a question of analogy but of _Identity_. The Natural Laws are not the shadows or images of the Spiritual in the same sense as autumn is emblematical of Decay, or the falling leaf of Death. The Natural Laws, as the Law of Continuity might well warn us, do not stop with the visible and then give place to a new set of Laws bearing a strong similitude to them. The Laws of the invisible are the same Laws, projections of the natural not supernatural. Analogous Phenomena are not the fruit of parallel Laws, but of the same Laws--Laws which at one end, as it were, may be dealing with Matter, at the other end with Spirit. As there will be some inconvenience, however, in dispensing with the word analogy, we shall continue occasionally to employ it. Those who apprehend the real relation will mentally substitute the larger term. Let us now look for a moment at the present state of the question. Can it be said that the Laws of the Spiritual World are in any sense considered even to have analogies with the Natural World? Here and there certainly one finds an attempt, and a successful attempt, to exhibit on a rational basis one or two of the great Moral Principles of the Spiritual World. But the Physical World has not been appealed to. Its magnificent system of Laws remains outside, and its contribution meanwhile is either silently ignored or purposely set aside. The Physical, it is said, is too remote from the Spiritual. The Moral World may afford a basis for religious truth, but even this is often the baldest concession; while the appeal to the Physical universe is everywhere dismissed as, on the face of it, irrelevant and unfruitful. From the scientific side, again, nothing has been done to court a closer fellowship. Science has taken theology at its own estimate. It is a thing apart. The Spiritual World is not only a different world, but a different kind of world, a world arranged on a totally different principle, under a different governmental scheme.
