2. This Atheistic theory rests entirely on a supposed discovery of M. Comte,--the discovery of _a law of human development_, which serves at once to account for the origin and prevalence of Theological beliefs in the past, and to insure their utter disappearance in the future; a law which, like the magician's wand, can raise the apparition, and then lay it again! Now, of this law we affirm and undertake to prove that it is _utterly groundless_; that it has no solid basis of evidence on which it can be established; that it is contradicted by the history of the world, and opposed to our own experience at the present day. It can scarcely be imagined that a man accustomed, as M. Comte has been, to the severe pursuits of Science, could give publicity to a law of this kind, and claim the credit of a great original discovery, without having some plausible reasons to plead for it; and he does assign certain reasons for his belief, which are, it may be safely affirmed, as frivolous and inconclusive as any that have ever been offered in support of the most baseless revery. They may be reduced to THREE; the _first_, derived from our cerebral organization; the _second_, from the history of a certain portion of our species; the _third_, from the analogy of our individual experience.[71] He founds, in the first instance, on our _cerebral organization_. He is an ardent admirer of Drs. Gall and Spurzheim, and has no scruple in avowing himself a decided Materialist. It is unnecessary here to enter on a discussion of Materialism, or even of Phrenology,--that will be done hereafter; in the mean time it is enough merely to indicate the fact that the theory proceeds on that ground, and then to inquire _how the fundamental law of Development is deduced from it_. How does the theory of Materialism, or even of Phrenology, were it assumed on the one side and admitted on the other, contribute to the establishment or verification of that law? Suppose it to be conceded that every mental faculty or propensity has a distinct cerebral organ, or, more generally, that the brain may be divided into three parts, representing, respectively, the animal propensities, the more elevated sentiments, and the intellectual faculties; could it be rationally inferred from this concession that human nature must necessarily develop itself after a certain order or method, and especially in the precise way that is indicated in M. Comte's law? Would it prove that Man must needs pass, in the process of his mental and social development, through _three_ distinct and successive stages,--the preparatory Theological state, the transitory Metaphysical state, and the final Positive state? Would it prove that Religion must first exist as Fetishism, then as Polytheism, then as Monotheism, and thereafter disappear from the earth altogether on the advent of M. Comte? He seems to think that there is a real connection between the cerebral theory and his great fundamental law;
