is plainly the Genesis of Moses!"[37] It will be observed that this strange speculation goes far beyond the comparatively modest conjecture of La Place. It postulates _nothing_, and undertakes to account for _everything_. In flagrant opposition to the old atheistic maxim, "Ex nihilo, nihil," it boldly affirms, "Ex nihilo, omnia." It speaks, indeed, of "laws in accordance with which the world took its origin;" but these laws must be as abstract as those of Mathematics, since they existed before matter itself; nay, more abstract, or, rather, more inconceivable still, since they existed, it would seem, even before Mind! Dr. Oken attempts to explain the production of the world from nothing by comparing it to the evolution of Arithmetical and Mathematical Science, out of the fundamental conception of _zero_! But, waiving this, we shall direct our attention to the only points in this theory which, in the existing state of speculative thought, can be held to have any practical interest in connection with our great theme. That theory attempts to account for the production both of the FLORA and the FAUNA of the natural world by _the process of Development_ rather than by _the miracle of Creation_. It proceeds on the assumption, akin to that of Epicurus, that atoms or monads alone existed in the first instance; and that from these were derived, under the action of natural law and by a process of gradual development, all existing substances and beings, whether organic or inorganic, mineral, vegetable, or animal. "No organism has been created," says Dr. Oken, "of larger size than an infusorial point. No organism is, nor ever has one been created, which is not microscopic. Whatever is larger has not been created, but developed. Man has not been created, but developed." On this fundamental assumption the whole theory is based. But we must carefully distinguish between the Atomic Theory and the application which is here made of it. The recent discoveries of Chemistry, by which all material compounds have been decomposed into their constituent elements, amounting to little more than fifty substances, which are either the primary or the proximate bases of all existing bodies, and the marvellous transformations which these elementary principles undergo, in respect alike of form, of density, of solidity, and of magnitude, under the action of natural laws,--may serve to make it credible that there is no _a priori_ impossibility in the assumption on which the Atomic Theory depends. Had it been the will of God to call into being the various vegetable and animal races in the way of gradual evolution out of these primary monads, no enlightened Theist will presume to say that it was either impossible, or inconsistent with His wisdom to do so. It must be observed, however, that the natural analogies which have sometimes been appealed to in support of this hypothesis, labor under a grievous defect when they are applied to account for the origin of the existing races,
