According to this view of Leibnitz, all living organisms have their own essence, or essential qualities and characteristics. They have been from all eternity in the "Divine Intendment," and can undergo no changes or modifications which shall make them essentially different from what they were in the beginning, or are now. This is not only true of the "germs" that are "in themselves upon the earth," but of every living thing, whether lying within or beyond the telescopic or microscopic limits. As a law of causation, as well as of consecutive thought, there must be in the order of life (all life) a continuous chain of ideas linking the past to the present, the present to the future, and the future to eternity. But that this continuous chain is dependent on mere physical changes or manifestations, is a logical induction utterly incapable of being exhibited in scientific formulæ. The higher and more satisfactory induction is that which places cause before effect, the Maker before the made, the Creator before the creature, and so on, in the analogical order, till the smallest conceivable "vital unit" is reached in the universe of organic matter. To begin, therefore, with microscopic observation, at a point in the ephemeromorphic world where that optical instrument fails to give back any intelligible answer, and synthetically follow this chain of causation upward and outward to Dr. Tyndall's "fiery cloud of mist," in which it is assumed that all the diversified possibilities and potentialities of the universe once lay latent, may answer the logical necessities of the "Evolution" theory, but will never satisfy the inductive processes of a Plato, a Leibnitz, or a Newton. Professor Tyndall, in speaking of his "fiery-cloud" theory, says: "Many who hold the hypothesis of natural evolution would probably assent to the position (his position) that at the present moment all our philosophy, all our poetry, all our science, all our art,--Plato, Shakespeare, Newton, and a Da Vinci--are potential in the fires of the sun." But, to be consistent in their inductions, they should proclaim themselves sun-worshippers at once, and ascribe to that transcendent luminary all the potentialities of a universe "Fresh-teeming from the hand of God."
