without special formative interposition, and by the mere force of what you call natural causes, were equal to the production of such phenomena as the division of the sexes and all that follows that division. Can it with any truth he said that the so-called natural causes have produced any phenomena which can be compared, on the question of special design, to the phenomena of the sexual division, the law of sexual procreation, and the whole system of the multiplication of individuals of distinct and true species? When I can see any facts which will warrant the belief that the origin of the sexes is to be attributed to the capacity of organizable protein to form itself into new compounds, to the capacity of these new compounds to become living organisms, and to the capacity of these living organisms, without the intervention of any formative will specially designing the result, to divide themselves into related forms of male and female, to establish for themselves the law of procreation, and to limit that procreation to the same species, I shall, perhaps, begin to see some ground for the superior claims of the evolution hypothesis. I should like, by-the-by, to see a system of classification of animal organisms, based exclusively on the distinction between the bisexual and the unisexual, or the non-sexual, methods of reproduction, and without running it out into the analogies of the vegetable world. I fancy that it would be found extremely difficult to account for the bisexual division without reaching the conclusion that it required and was effected by a special interposition. At all events, I should like to see it explained how the asexual and the unisexual construction passed into the bisexual by the mere operation of what you call natural causes. KOSMICOS. You said, a while ago, that you had never learned any nursery-stories. Yet, all along, you seem to me to have been under the influence of the Mosaic account of the creation. Of course you have read it, and, although you did not learn anything about it in childhood, and now try to treat it solely as a hypothesis, without any regard to its claims as a divinely inspired narrative, it is certainly worth your while to see how completely it becomes an idle tale of the nursery when scientific tests are applied to it. Hear what Spencer says about the creation of man, as given by Moses: "The old Hebrew idea that God takes clay and molds a new creature, as a potter might mold a vessel, is probably too grossly anthropomorphic to be accepted by any modern defender of special creations."
