To begin with begging the question, and then adroitly whipping the argument about a pivotal point, as a boy would whip a top, may be amusing enough to the childish mind, but is manifestly making no more progress in logic than to substitute an ingenious paraphrase of a term for its real definition. It is a mere verbal feat at best, without the possibility of reaching any determinate judgment. It is like some of the half-circular phrases we are likely to meet with in the categories of modern materialistic science, such as the "correlated correlates of motion," the "potentiated potentialities of sky-mist," the "undifferentiated differentialities of life-stuff," called, by special condescension on the part of the materialists, "life." All of which is an easy logic, but a whimsical enough way of putting it. According to Leibnitz, everything that exists is replete with life, full of vital activity, if not an actual mass of living individualities. But this daring hypothesis has ceased to attract the attention it once received. There are states and conditions of matter in respect to which it is idle to predicate the _vis vitae_. For the great bulk of our globe is made up of the highly crystallized and non-fossiliferous rocks, which neither contain any elementary principle of life, nor exhibit the slightest trace of vital organism, even to the minutest living speck or plastid. During all those vast periods of uncomputed time, covering the world's primeval history, there was an utter absence of life until the chief upheavals of the outer strata of our globe, now constituting the principal mountain chains of its well-defined continents, occurred. In whatever atomic or molecular theories, therefore, we may indulge, in respect to the original formation of the earth, the utmost stretch of empirical science can go no further, in the solution of vital problems, than to touch the threshold of inorganic matter, where, in our backward survey of nature, vegetable life begins and animal life ends. All beyond this point must be given up to other "correlates of motion" than those to which the materialists specifically assign the beginnings of life. The theory of "panspermism," originating with the Abbé Spallanzani in modern times, and still stoutly advocated by M. Pasteur and some few others, is manifestly defective in this,--that it goes beyond the inorganic limit in assigning vital units to all matter, even to its elemental principles. It is true that they speak of "pre-existing germs"--"primordial forms of life"--that are "many million times smaller than the smallest visible insect." But their assumptions go far beyond the construction we give to the Bible genesis, which merely asserts that the germinal principle of life--that of every living thing--is in the earth, or in "the waters and the earth," which were alone commanded "to bring forth."
