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 marvelously 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.[71] 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?
But these are questions of quality; and the moment we pass from quantity to quality we leave Science behind. In the vocabulary of Science, Eternity is only the fraction of a word. It means mere everlastingness. To Religion, on the other hand, Eternity has little to do with time. To correspond with the God of Science, the Eternal Unknowable, would be everlasting existence; to correspond with "the true God and Jesus Christ," is Eternal Life. The quality of the Eternal Life alone makes the heaven; mere everlastingness might be no boon. Even the brief span of the temporal life is too long for those who spend its years in sorrow. Time itself, let alone Eternity, is all but excruciating to Doubt. And many besides Schopenhauer have secretly regarded consciousness as the hideous mistake and malady of Nature. Therefore we must not only have quantity of years, to speak in the language of the present, but quality of correspondence. When we leave Science behind, this correspondence also receives a higher name. It becomes communion. Other names there are for it, religious and theological. It may be included in a general expression, Faith; or we may call it by a personal and specific term, Love. For the knowing of a Whole so great involves the co-operation of many parts.
Communion with God--can it be demonstrated in terms of Science that this is a correspondence which will never break? We do not appeal to Science for such a testimony. We have asked for its conception of an Eternal Life; and we have received for answer that Eternal Life would consist in a correspondence which should never cease, with an Environment which should never pass away. And yet what would Science demand of a perfect correspondence that is not met by this, _the knowing of God_? There is no other correspondence which could satisfy one at least of the conditions. Not one could be named which would not bear on the face of it the mark and pledge of its mortality. But this, to know God, stands alone. To know God, to be linked with God, to be linked with Eternity--if this is not the "eternal existence" of biology, what can more nearly approach it? And yet we are still a great way off--to establish a communication with the Eternal is not to secure Eternal Life. It must be assumed that the communication could be sustained. And to assume this would be to beg the question. So that we have still to prove Eternal Life. But let it be again repeated, we are not here seeking proofs. We are seeking light. We are merely reconnoitring from the furthest promontory of Science if so be that through the haze we may discern the outline of a distant coast and come to some conclusion as to the possibility of landing.
