If the universe as it is, with the infinite variety of beings which people it and the marvellous relations which connect these beings mutually together, could be shown to have sprung all at once from nothing, or to have emerged from chaos at a given instant, in its full harmony, the boldest mind would not venture to regard this miracle of intelligence as the product of chance. But modern science, it is said, no longer admits of this simple explanation of things: "God created the heavens and the earth." This phrase is henceforward admissible only in the catechism. We know that all has been produced by slow degrees, starting from weak and shapeless rudiments. This grand marvel of the universe was not made all of one piece. Man is of recent date; quadrupeds at a certain epoch did not exist; animals had a beginning, and plants also. The earth was once bare. Formerly, it was perhaps only a gaseous mass revolving in space. In course of time, matter was condensed; in time it was organized in living cellules; in time these cellules became shapeless animals; in time these animals were perfected. Time appears therefore to be the "universal factor"; and for the ancient formula, "the universe is the creation of God," we are able to substitute this other formula, the result, most assuredly, of modern science, "the universe is the work of time." In all this, Gentlemen, I have invented nothing. All I have done has been to put into form the theory, the elements of which I have met with in various contemporary productions.[120] They bewilder us by heaping ages upon ages, and in order to explain nature they substitute the idea of time for the ideas of power and intelligence. They seem to suppose that what is produced little by little is sufficiently explained by the slowness of its formation. These aberrations of thought have recently been manifested in a striking manner on the occasion of the publication of Mr. Darwin's book. This naturalist has given his attention to the transformation of organized types. He has discovered that types vary more than is generally supposed; and that we probably take simple varieties for distinct species. His discoveries will, I suppose, leave traces strongly marked enough in the history of science. But Mr. Darwin is not merely an observer; he is a theorist, dominated evidently by a disposition to systematize. Now minds of this character, which render, no doubt, signal services to the sciences of observation, are all like Pyrrhus, who, gazing on Andromache as he walked by her side, Still quaffed bewildering pleasure from the view.[121]
