The whole controversy, as at present conducted by the materialists and vitalists, resolves itself into this one question:--Whether life springs from what Dr. Harvey calls a "primordium,"--a pre-existing vital germ or unit--or whether it originates _de novo_, as the materialists assert, from infusions contained in their experimental flasks, or from plastide particles contained in protoplasmic matter, or from the still more daring hypothesis of "molecular machinery" as worked by molecular force? It is certain that the materialistic theory is quite as inexplicable, on the basis of analogical reasoning and microscopical investigation, as that indicated in the Bible Genesis; while the vitalistic theory would seem to be more in harmony with vital phenomena, and hence the more rational hypothesis of the two. Besides, the Bible Genesis answers to the logical necessity of predicating a determinate cause for each and every vital effect, or each living organism apparently springing from plasmic conditions or mere structureless matter. Whenever the seeds of plants or trees are actually planted or sown in the earth, this logical necessity rests on an induction impregnably laid in cause and effect; while the materialistic dogma, _nihil ex nihilo_, would necessitate a like induction wherever seed is not sown. In either case the change that ensues is manifestly due to vital properties, whether the same be inhering in the seed, or in necessary environing conditions. And the vital processes are the same, with the single difference as to actual environment. The germ in the seed is capable of assimilating, by well-determined and thoroughly specialized processes, the nutrient matter contained in its environment, precisely as the "primordial germ" develops under its environing conditions. From the moment they strike their rootlets into the ground, the processes of development and growth are the same. The only point, however, necessary to make in this connection, is, that when we go back to the first living organism of a species--its primordially developed form--we necessarily reach environing conditions within which there is no such thing as a germ-cell with an exterior environment corresponding to the testa of seeds, or to any conceivable notion we may have of seeds themselves.
