Professor Moore, of Liverpool University, as I have already pointed out while discussing the term “vital force,” invents a new phrase, “biotic energy,” to explain the same phenomena. Surely a force by any other name is no more and no less potent. Both Verworn and Moore feel the need, as we all do, of some term, or terms, by which to explain that activity in matter which we call vital. Other writers have referred to “a peculiar power of synthesis” in plants and animals, which the inanimate forms do not possess.
Ray Lankester, to whom I have already referred in discussing this subject, helps himself out by inventing, not a new force, but a new substance in which he fancies “resides the peculiar property of living matter.” He calls this hypothetical substance “plasmogen,” and thinks of it as an ultimate chemical compound hidden in protoplasm. Has this “ultimate molecule of life” any more scientific or philosophical validity than the old conception of a vital force? It looks very much like another name for the same thing–an attempt to give the mind something to take hold of in dealing with the mystery of living things. This imaginary “life-stuff” of the British scientist is entirely beyond the reach of chemical analysis; no man has ever seen it or proved its existence. In fact it is simply an invention of Ray Lankester to fill a break in the sequence of observed phenomena. Something seems to possess the power of starting or kindling that organizing activity in a living body, and it seems to me it matters little whether we call it “plasmogen,” or a “life principle,” or “biotic energy,” or what not; it surely leavens the loaf. Matter takes on new activities under its influence. Ray Lankester thinks that plasmogen came into being in early geologic ages, and that the conditions which led to its formation have probably never recurred. Whether he thinks its formation was merely a chance hit or not, he does not say.
We see matter all about us, acted upon by the mechanico-chemical forces, that never takes on any of the distinctive phenomena of living bodies. Yet Verworn is convinced that if we could bring the elements of a living body together as Nature does, in the same order and proportion, and combine them in the selfsame way, or bring about the vital conditions, a living being would result. Undoubtedly. It amounts to saying that if we had Nature’s power we could do what she does. If we could marry the elements as she does, and bless the banns as she seems to, we could build a man out of a clay-bank. But clearly physics and chemistry alone, as we know and practice them, are not equal to the task.
