But the Darwinian systematizers object that science must limit itself to a coordination of the known relations of things in the universe, or deal only with phenomenal facts, not dogmatisms; forgetting that they dogmatize quite as extensively, in constructing their chain of generation, as the theologians do in adhering to the Bible genesis. No theologian objects to a rational synthesis of phenomena, limited to sensible experience; but, in climbing from law to law, he reasonably enough insists, that, when concrete facts rise into abstract conceptions, the highest round in the ladder shall not be knocked out for the accommodation of Robert G. Ingersoll or any other boasted descendant of a gorilla. And he also insists that when _a priori_ speculation is lost in abstract conceptions, the highest must necessarily press alone upon the intuitions of consciousness, where all generalizations cease, and all synthesis is undeniably at an end. Here, in this mysterious chamber of the soul, we stand silent and alone, with only dim and shadowy phantoms about us, as if in the august presence of Deity itself. But how does scientific speculation propose to stifle these intuitions of consciousness--reduce them to the least of all potential factors in the universe? We will take the very latest of these speculations. In supplementing both the Darwinian theory and the grander speculation of Laplace, the scientists, so called, tell us that the process of aggregation, or the turning out of new worlds in the universe, is still going on; but that the time is coming when all the primeval potency or energy, originally inhering in diffused matter, will have exhausted itself in actual energy, and that then all light, life and motion in the universe, will cease and be at an end. This dissipation of potential energy is to result, they say, in a played-out universe, as it has already resulted, they claim, in a played-out moon, if not countless other heavenly bodies.[38] All the exterior planets, or a majority of them at least, are to be placed in this category of dismantled worlds, or those in which all life has hopelessly ceased and become extinct. All has utterly disappeared, or, to paraphrase one of Pope's couplets, "Beast, bird, fish, insect--what no eye can scan, Nor glass can reach--from zoophyte to man." All these dismantled planets, and satellites to planets, are only so many immense cinders--mere refuse slag--of no conceivable interest to science, except to predicate the ultimate conclusion--"a played-out universe, resulting from a played-out potency within the universe." The magnificent clockwork of the heavens will then have run down, with no Darwinian whirligig to wind it up again, and the terrible reality of Byron's dream, which it would seem was not all a dream, be realized in the bright sun extinguished, the stars darkling the eternal space, rayless and pathless, and the icy earth swung blind and blackening in the moonless air.
