It is here that we find the value of the maxim "Nature unaided fails." The more we consider this maxim and the principle of Unity and Continuity, the clearer it will become, that Limitation is no part of the Law itself, but results only from our own limited comprehension of it; and that St. James uses no meaningless phrase, but is stating a logical and scientific truth, when he speaks of "The perfect Law of Liberty" (Jas. i, 25). What we have to do is, to follow this up, not by petulant self-assertion, but by quietly considering the why and wherefore of the whole thing. In doing so we can fortify ourselves with another maxim, that "Principle is not limited by Precedent." When we spread the wings of thought and speculate as to future possibilities, our conventionally-minded friends may say we are talking bosh; but if you ask them why they say so, they can only reply that the past experience of the whole human race is against you. They do not speak like this in the matter of flying-machines or carriages that go without horses; they say these are scientific discoveries. But when it comes to the possibilities of our own souls, they at once set a limit to the expansion of ideas, and do not see that the scientific principle of discovery is not confined to laboratory experiments. Therefore, we must not let ourselves be discouraged by such arguments. If our friends doubt our sanity, let them doubt it. The sanity of such men as Galileo and George Stephenson was doubted by their contemporaries, so we are in good company. At the same time we must not neglect to look after our own sanity. We must know some intelligible reason for our conclusions, and realize that however unexpected, they are the logical carrying out of principles which we can recognize in the Creation around us. If we do this we need not fear to spread the wings of fancy, even though some may not be able to accompany us; only we must remember that we are using wings. Fancy, in the ordinary acceptation of the word, has really no wings; it is like a balloon that just floats wherever any passing current of air may drive it. The possession of wings implies power to direct our flight, and fancy must be converted into trained Imagination, just as the helpless balloon has been superseded by navigable air-craft. It must be "the scientific imagination"; and the "scientific imagination" carried into the world of spiritual causation becomes the Word of Power, and its Power is derived from the fact that it is always working according to Law. Then we may go on confidently, because we are following the same universal principles by which all creation has been evolved, only now we are specializing its action from the standpoint of our own individuality, according to the ancient teaching that Man, the Microcosm, repeats in himself all the laws of the Macrocosm, or great world, around him.
