The further definition, moreover, of this correspondence as _knowing_ is in the highest degree significant. Is not this the precise quality in an Eternal correspondence which the analogies of Science would prepare us to look for? Longevity is associated with complexity. And complexity in organisms is manifested by the successive addition of correspondences, each richer and larger than those which have gone before. The differentiation, therefore, of the spiritual organism ought to be signalized by the addition of the highest possible correspondence. It is not essential to the idea that the correspondence should be altogether novel; it is necessary rather that it should not. An altogether new correspondence appearing suddenly without shadow or prophecy would be a violation of continuity. What we should expect would be something new, and yet something that we were already prepared for. We should look for a further development in harmony with current developments; the extension of the last and highest correspondence in a new and higher direction. And this is exactly what we have. In the world with which biology deals, Evolution culminates in Knowledge. At whatever point in the zoological scale this correspondence, or set of correspondences, begins, it is certain there is nothing higher. In its stunted infancy merely, when we meet with its rudest beginnings in animal intelligence, it is a thing so wonderful, as to strike every thoughtful and reverent observer with awe. Even among the invertebrates so marvellously are these or kindred powers displayed, that naturalists do not hesitate now, on the ground of intelligence at least, to classify some of the humblest creatures next to man himself. [1] Nothing in nature, indeed, is so unlike the rest of nature, so prophetic of what is beyond it, so supernatural. And as manifested in Man who crowns creation with his all-embracing consciousness, there is but one word to describe his knowledge; it is Divine. If then from this point there is to be any further Evolution, this surely must be the correspondence in which it shall take place? This correspondence is great enough to demand development; and yet it is little enough to need it. The magnificence of what it has achieved relatively, is the pledge of the possibility of more; the insignificance of its conquest absolutely involves the probability of still richer triumphs. If anything, in short, in humanity is to go on it must be this. Other correspondences may continue likewise; others, again, we can well afford to leave behind. But this cannot cease. This correspondence--or this set of correspondences, for it is very complex--is it not that to which men with one consent would attach Eternal Life? Is there anything else to which they would attach it? Is anything better conceivable, anything worthier, fuller, nobler, anything which would represent a higher form of Evolution or offer a more perfect ideal for an Eternal Life?
