Under Mr. Darwin’s system “community of descent” and not “some unknown plan of creation” is “the hidden bond” which unites together all living existences of our globe. “Looking to some unknown plan of creation” (in his own words) has prevented the truly scientific classification and history of the forms of life in our world. The Bible has stood in the way of the growth of science.――――Under his system the changes by natural descent from any given parent to its offspring, taken individually, have been exceedingly small. Hence the theory requires an indefinitely long time from the point of the original creation of the four or five primordial forms to the present status of living things, vegetable and animal, in our world.――――The above remarks will suffice for a very general introduction to Mr. Darwin’s system. Wishing to bring this discussion within the narrowest possible limits and yet do justice to Darwin, to Genesis, and to the truth, I propose to state briefly his main arguments; then comprehensively my rejoinder to them severally in their order, and then subjoin some general considerations bearing upon his entire theory. 1. Darwin holds that by natural law the offspring vary, though slightly, from the parent, and hence, that, given an indefinitely long time, he has any desired amount of variation. 2. When animals multiply beyond the means of subsistence, there ensues a struggle for life in which the strongest and most favored in circumstances are the victors and survive. This law which he calls “Natural Selection” (or “the survival of the fittest”) works a gradual improvement in the race. A twin argument with this comes from “sexual selection,” the amount of which is that in the case of some at least of the animal races, there arises a struggle among the males for the possession of the females, in which struggle the most attractive in beauty or in song, or the champions in fight, being the victors, perpetuate the race and thus improve it. This law of the animal races (“sexual selection”) works precisely in the same line with the law called “natural selection.” It may serve therefore to provide a little more of the same thing, but no new or different product whatever. Hence it does not seem to call for a distinct refutation. 3. Homologous anatomical structure is found to obtain very extensively among widely diverse races, _e. g._ in the arm of man, the fore-leg of the monkey and indeed of all quadrupeds, in the wing of the bird and the fin of the fish. This indicates a common parentage. 4. Some animals which, fully grown, differ from each other widely, are scarcely distinguishable in the embryo. Hence he infers their common origin. 5. The fact of rudimentary organs is assumed to be _historic_, proving that some ancient progenitor used them, and that they have gradually passed out of use. This is held to prove that great changes of structure come of genealogical descent. BRIEF REPLIES.
