To which there is a twofold reply. In the first place, to go outside what we call Nature is not to go outside Environment. Nature, the natural Environment, is only a part of Environment. There is another large part which, though some profess to have no correspondence with it, is not on that account unreal, or even unnatural. The mental and moral world is unknown to the plant. But it is real. It cannot be affirmed either that it is unnatural to the plant; although it might be said that from the point of view of the Vegetable Kingdom it was _supernatural_. Things are natural or supernatural simply according to where one stands. Man is supernatural to the mineral; God is supernatural to the man. When a mineral is seized upon by the living plant and elevated to the organic kingdom, no tresspass against Nature is committed. It merely enters a larger Environment, which before was supernatural to it, but which now is entirely natural. When the heart of a man, again, is seized upon by the quickening Spirit of God, no further violence is done to natural law. It is another case of the inorganic, so to speak, passing into the organic.
But, in the second place, it is complained as if it were an enormity in itself that the spiritual correspondence should be furnished from the spiritual world. And to this the answer lies in the same direction. Correspondence in any case is the gift of Environment. The natural Environment gives men their natural faculties; the spiritual affords them their spiritual faculties. It is natural for the spiritual Environment to supply the spiritual faculties; it would be quite unnatural for the natural Environment to do it. The natural law of Biogenesis forbids it; the moral fact that the finite cannot comprehend the Infinite is against it; the spiritual principle that flesh and blood cannot inherit the kingdom of God renders it absurd. Not, however, that the spiritual faculties are, as it were, manufactured in the spiritual world and supplied ready-made to the spiritual organism--forced upon it as an external equipment. This certainly is not involved in saying that the spiritual faculties are furnished by the spiritual world. Organisms are not added to by accretion, as in the case of minerals, but by growth. And the spiritual faculties are organized in the spiritual protoplasm of the soul, just as other faculties are organized in the protoplasm of the body. The plant is made of materials which have once been inorganic. An organizing principle not belonging to their kingdom lays hold of them and elaborates them until they have correspondences with the kingdom to which the organizing principle belonged. Their original organizing principle, if it can be called by this name, was Crystallization; so that we have now a distinctly foreign power organizing in totally new and higher directions. In the spiritual world, similarly, we find an organizing principle at work among the materials of the organic kingdom, per forming a further miracle, but not a different kind of miracle, producing organizations of a novel kind, but not by a novel method. The second process, in fact, is simply what an enlightened evolutionist would have expected from the first. It marks the natural and legitimate progress of the development. And this in the line of the true Evolution--not the _linear_ Evolution, which would look for the development of the natural man through powers already inherent, as if one were to look to Crystallization to accomplish the development of the mineral into the plant,--but that larger form of Evolution which includes among its factors the double Law of Biogenesis and the immense further truth that this involves.
What is further included in this complex correspondence we shall have opportunity to illustrate afterwards. [1] Meantime let it be noted on what the Christian argument for Immortality really rests. It stands upon the pedestal on which the theologian rests the whole of historical Christianity--the Resurrection of Jesus Christ.
