Nature, as was said above, is a book of God's revelation, written within and without. The outer part of this sacred volume attests the supreme power, wisdom, and goodness of the Creator in characters too clear and luminous to be unperceived or misread by the dullest or the most vitiated eye. The inner pages of this book comprise a still more glorious revelation of God--but their language is more mysterious, and much which they contain seems to have been wisely withheld, or rather withdrawn from the knowledge of mankind. It was this acquaintance with the internal secrets of Nature, derived partly from revelation, and partly from intuition, which gave the men of the primitive, and especially the ante-diluvian, world such a vast superiority over all the succeeding generations of mankind. But it was the abuse of that knowledge, also, which brought about in the primeval world a Satanic delusion, and a gigantic moral and intellectual corruption, of which we can now scarcely form the remotest idea. But this key to the inward science of Nature, which was taken away from a corrupt world, that had so grossly abused it, seems now about to be restored to man, renovated as his soul and intelligence have been by a long Christian education. The physical researches of the last fifty years, especially in Germany, lead the enquirer more and more to the knowledge of this important truth, stamped on all the pages of ancient tradition, and never effaced from the recollection of mankind, to wit, the action of spiritual intelligences on the material world. The nature of this action is briefly adverted to in the following passage (among many others to the same purport), in the Philosophy of Life. "It is especially of importance," says the author, "for the understanding of the general system of Nature, to observe how the modern chemistry mostly dissolves and decomposes all solid bodies, as well as water itself, into different forms of elements of air, and thereby has taken away from Nature the appearance of rigidity and petrifaction. There are every where living elemental powers hidden and shut up under this appearance of rigidity. The quantity of water in the air is so great that it would suffice for more than one deluge; a similar inundation of light would occur, if all the light latent in darkness were at once set free; and all things would be consumed by fire, if that element in the quantity in which it exists, were suddenly let loose. The salutary bonds, by which these elemental powers are held in due equilibrium, one bound by the other, and kept within its prescribed limits, I will not now make a matter of investigation; nor now examine the question, whether _these bonds be not perhaps of a higher kind than naturalists commonly suppose_."
