It will be found, in the great majority of cases, and especially in the case of ardent youthful minds, that this theory, when it is embraced as an article of their philosophic creed, is, to all practical purposes, tantamount to Atheism.

For not to insist on the consideration, so forcibly stated by others,[55] that the natural argument for the Immortality of Man, or for the doctrine of a Future Life, as implying distinct individuality and continued self-consciousness, must be materially weakened, if not entirely neutralized, by a theory of development which traces the human lineage up through the monkeys and fishes to albumen impregnated by electricity, or, further still, to a diffused Nebula or universal Fire-Mist,--we think that the Sensational and Materialistic speculations with which the work abounds have a tendency to weaken the evidence for a living, personal, spiritual God, as the Creator and Moral Governor of the world, and to diminish that reverence, confidence, and love, which these aspects of His character alone can inspire.

The system of Epicurus, although it contained a formal recognition of a First Cause, has always been held to be practically atheistic, simply because it removed God from the active superintendence of the affairs of the world, and excluded the doctrine of a special providence and of a moral government.

It was held, in the words of Cicero, "Epicurum verbis reliquisse Deos,--re sustulisse."[56] And so, in "The Vestiges," Natural Law is substituted for Supernatural Interposition, not only in the common course of Providence, but in the stupendous work of Creation itself.
SECTION III.
THEORY OF _SOCIAL_ OR _HISTORICAL_ DEVELOPMENT .-- AUGUSTE COMTE.
It might have been thought that the principle of Development had exhausted its powers, and achieved its highest triumphs, when it had been applied successively to account, first, for the creation of planets and astral systems, and, secondly, for the production of vegetable and animal life; and that little could remain for it to do after it had succeeded in tracing the genealogy of MAN back, in a direct line through many generations, to the nebulous matter or luminous Fire-Mist which was diffused at the beginning of time throughout the Universe.

But, on a more careful study of its last and highest product,--MAN, with his intellectual and moral nature, his religious beliefs, his social history, and his immortal hopes,--it seemed as if there were still some phenomena which remained to be accounted for, some facts of palpable reality and great magnitude which had not yet been adequately explained.
The mental faculties and their operations, the moral laws that are universally recognized and appealed to, the social institutions which have been established, the religious beliefs and feelings which have generally prevailed, and the rites of worship which have been observed in all ages and climes, were so widely different from the phenomena of mere vegetable or animal life, that they seemed to demand a distinct account of their origin; and it might not be apparent, at first sight, how they could be reduced under the same all-pervading law by which the planets were formed, so as to exclude all idea of Divine supernatural interposition.
