As the Church-Christians regard the foundation of their church as the only origin of true knowledge of God, and only out of a kind of courtesy admit that former believers may also be regarded as having formed a church; so in precisely the same manner does Positive science, according to its own statement, place its origin in Comte: and its representatives, also only out of courtesy, admit the existence of previous science, and that only as regarding certain thinkers, as, for instance, Aristotle. Both the Church and Positive science altogether exclude the ideas of all the rest of mankind, and regard all knowledge outside their own as _erroneous_. The similarity persists. Just as to the support of the first advental theological dogmas of the Trinity and of the divinity of Christ comes the old--but newly-interpreted--dogmas of man's fall and of his redemption by the death of Christ, and out of these dogmas is developed popular Church teaching: so in our time, the old dogma of Evolution comes in with new importance to help the fundamental dogma of Comte concerning the organism of mankind; and from these two elements the popular scientific doctrine has been formed. As in one teaching, so in the other: the new dogma is necessary for the support of the old one, and becomes comprehensible only in connection with it. If to a believer in the Divinity of Christ, it is not clearly comprehensible why God should come down to earth, the doctrine of atonement explains it. If it is not quite clear to a believer in the Organism of Mankind why a collection of individuals may be counted as an organism, the dogma of Evolution is charged with the explanation. This dogma is needed to reconcile the contradictions and certainties of the first: mankind is an organism, and we see that it does not contain the chief characteristic of an organism; how must we account for it? Here the dogma of evolution comes in, and explains, Mankind is an organism in a state of development. If you accept this, you may then consider mankind as such.
