has been given to Christianity to disclose the lines of a further Evolution. And if Science also professes to offer a further Evolution, not the most sanguine evolutionist will venture to contrast it, either as regards the dignity of its methods, the magnificence of its aims, or the certainty of its hopes, with the prospects of the Spiritual Kingdom. That Science has a prospect of some sort to hold out to man, is not denied. But its limits are already marked. Mr. Herbert Spencer, after investigating its possibilities fully, tells us, "Evolution has an impassable limit."[99] It is the distinct claim of the Third Kingdom that this limit is not final. Christianity opens a way to a further development--a development apart from which the magnificent past of Nature has been in vain, and without which Organic Evolution, in spite of the elaborateness of its processes and the vastness of its achievements, is simply a stupendous _cul de sac_. Far as nature carries on the task, vast as is the distance between the atom and the man, she has to lay down her tools when the work is just begun. Man, her most rich and finished product, marvelous in his complexity, all but Divine in sensibility, is to the Third Kingdom not even a shapeless embryo. The old chain of processes must begin again on the higher plane if there is to be a further Evolution. The highest organism of the Second Kingdom--simple, immobile, dead as the inorganic crystal, toward the sphere above--must be vitalized afresh. Then from a mass of all but homogeneous "protoplasm" the organism must pass through all the stages of differentiation and integration, growing in perfectness and beauty under the unfolding of the higher Evolution, until it reaches the Infinite Complexity, the Infinite Sensibility, God. So the spiritual carries on the marvelous process to which all lower Nature ministers, and perfects it when the ministry of lower Nature fails.
