Chapter III

. as a standpoint of general validity in relation to teleology and theology would still hold good. Even an entirely naïve, anthropomorphic, “supernatural” theology is ready to see, in the natural course of things, in the “_causæ secundariæ,_” the realisation of Divine purpose, teleology, and does not fail to recognise that the Divine purpose may fulfil itself not only in an extraordinary manner, through “miracles” and “unconditioned” events, but also in ordinary ways, “through means” and the universal causal nexus. Thus it is quite consistent even with a theology of this kind to regard the whole system of causes and effects, which, according to the Darwin-Weismann doctrine, have gradually brought forth the whole diversity of the world of life, with man at its head, in a purely causal way without teleological intervention, as an immense system of means marvellous in its intricacy, in the inevitable necessity of its inter-relations, and in the exactness of its work, the ultimate result of which _must_ have come about, but perhaps at the same time was _intended_ to come about. Whether I regard this ultimate result as the mere consequence of blind happenings, or as an intended purpose, does not depend, as we have seen, upon the knowledge gained by natural science, but depends above all on whether this ultimate result seems to me of sufficient _value_ to be thought of as the purpose of a world-governing intelligence, and thus depends upon my personal attitude to human nature, reason, mind, and the spiritual, religious, and moral life. If I venture to attribute worth, and absolute worth, to these things, nothing, not even the fact of the “struggle for existence” in its thousand forms, in its gradually transforming effects, in the almost endless nexus of its causes and results, germinal selection included, can take away my right (and eventually my duty) to regard the ultimate result _as an end_, and the nexus of causes as a system of means. To enable me to do this, it is only requisite that internal necessity should govern the system, and that the result should not be a chance one, so that it might even have been suppressed, have failed, or have turned out quite differently. Necessity and predetermination are characteristic of the relation between means and purpose. But this requisite is precisely that which natural science does afford us,—namely, the proof that all phenomena are strictly governed by law, and are absolutely predetermined by their antecedents. At this point the religious and the scientific consideration coincide exactly. The hairs of our head, and the hairs in the fur of a polar bear, which is varying towards white, and is therefore selected in the struggle for existence,(36) even the fluctuating variations of a determinant in the germ, are “numbered” according to both conceptions. Every variation that cropped up, every factor that “selected” the fit, and eliminated the unfit, was strictly predestined, and must of necessity have appeared as, and when, and where it did appear.(37)

The whole nexus of conditions and results, the inclined plane of evolution and the power of Being to move up it, has its sufficient reason in the nature and original state of the cosmos, in the constitution of its “matter,” its “energy,” its laws, its sequences and the grouping of its phenomena. Only from beginnings so constituted could our present world have come to be as it is, and that necessarily. Only because the primary possibility and fitness for life—vegetable, animal and human—was in it from the beginning, could all these have come to be. This primary possibility did not “come into being,” it was _à priori_ immanent in it. Whence came this? There is no logical, comprehensible, or any other necessity why there should be a world at all, or why it should be such that life and evolution must become part of it. Where then lies the reason why it is, rather than is not, and why it is as it is?

To this must be added what Weismann himself readily admits and expressly emphasises. The whole theory treats, and must treat plant, animal, and man as only ingenious machines, mere systems of physical processes. This is the ideal aimed at—to interpret all the phenomena of life, growth, and reproduction thus. Even instincts and mental endowments are so interpreted, since there must be corresponding morphological variations of the fine structure of the nervous organ, and instinctive actions are then “explained” as the functions of these. But how “mechanical happening” comes to have this marvellous inwardness, which we call sensation, feeling, perception, thought and will, which is neither mechanical nor derivable from anything mechanical; and, further, how physical and psychical can condition one another without doing violence to the law of the conservation of the sum of energy, is an absolute riddle. But this whole psychical world exists, with graduated stages perhaps as close to each other as in the physical world, but even less capable than these of being explained as having arisen out of their antecedent lower stages. And this psychical world, which is, indeed, related to and dependent upon the corporeal life, as also conversely, has its own quite peculiar laws: thought does not follow natural laws, but those of logic, which is entirely indifferent to exciting stimuli, for instance of the brain, which conform to natural laws. But this world, its riddles and mysteries, its great content and its history, beyond the reach of mechanical theories, is so absolutely the main thing (especially in regard to the question of the possibility of religion), that the question of bodily structure and evolution becomes beside it a mere accessory problem, and even the last is only a relatively unimportant roundabout way of coming at the gist of the business. How completely the evolution of the higher mental faculties transcends such narrow and meagre formulæ as the struggle for existence and the like, Weismann himself indicates in connection with man’s musical sense, and its relation to the “musical” instinct in animals. The same and much more might be alleged in regard to the whole world of mind, of the æsthetic, ethical and religious, of the kingdom of thought, of science, and of poetry.

Natural Selection.

We have for the moment provisionally admitted the theory of natural selection, in order to see whether it could be included in a religious interpretation of things. But in reality such an admission is not to be thought of, in face of what is at present so apparent—the breaking down of this hypothesis, which has been upheld with so much persistence. We shall have to occupy ourselves with this later on. In the meantime a few more remarks must be added to what has been already said.

It might be said, paradoxically, that the worst fate that could befall this hypothesis would be to be proved, for then it would be most certainly refuted. What we mean is this: If it is really “utility” that rules the world and things, there can be no certainty and objectivity of knowledge, no guarantee of truth. The “struggle for existence” is not concerned with selecting beings who see the world as it is. It selects only the interpretation and conception of the environment that is most serviceable for the existence and maintenance of the species. But there is nothing to guarantee that the “true” knowledge will also be the most useful. It might quite well be that an entirely subjective and in itself wholly false interpretation would be the most serviceable. And if, by some extraordinary chance, the selected interpretation should be also the true one, there would be no means of establishing the fact. And what is true of this interpretation is true also of all theories that are derived from it, for example of the theory of selection itself.

Furthermore, a great part, perhaps the greatest part of the confidence placed in the theory of selection is due to an involuntary, but entirely fallacious habit of crediting it with the probabilities in favour of the doctrine of descent. The main arguments in favour of evolution and descent are very often, though unwittingly, adduced in support of Darwinism in

## particular. This is a great mistake. Take, for instance, the evidence of

the “palæontological” record. It affords hundreds of proofs of evolution, but not a single proof of selection. Its “intermediate” and “connecting links” do possibly prove the affiliation of species and the validity of genealogical trees. But precisely the “intermediate links” which _selection_ requires—the myriads of forms of life which were not successfully adapted, the unfit competitors in the struggle for existence which must have accompanied the favourably adapted variants from step to step, from generation to generation—these are altogether awanting.

Another circumstance seems to us to have been entirely overlooked, and it is one which gives the theory of selection an inevitable appearance of truth, even if it is essentially false, and thus makes it very difficult to refute. Assuming that the recognition of teleological factors is valid, that there is an inward law of development, that “Moses” or whoever one will was undoubtedly right, it is self-evident that, because of the indubitable over-production of organisms, there would even then be a struggle for existence on an immense scale, and that it would have a far-reaching “selective” influence, because of the relative plasticity of many forms of life. Beyond doubt it would, in the course of æons, have applied its shears to many forms of life, and probably there would be no organisms, organs, or associations in the evolution of the ultimate form of which it had not energetically co-operated. Its influence would, perhaps, be omnipresent, yet it might be far from being the all-sufficient factor in evolution; indeed, as far as the actual impulse of evolution is concerned, it might be a mere accessory. Unless we are to think of the forms of life as wholly passive and wooden, the struggle for existence must necessarily be operative, and the magnitude of its results, and their striking and often bizarre outcome, will tend ever anew to conceal the fact that the struggle is after all only an inevitable accompaniment of evolution. And thus we understand how it is that interpretations from the point of view of an inward law of development, of orthogenesis, or of teleology, notwithstanding their inherent validity, have _à priori_ always had a relatively difficult position as compared with the Darwinian view.

It is usual to speak of the “all-sufficiency of natural selection,” yet the champion of the selection-theory admits, as he needs must, that the struggle for existence and selection can of themselves create absolutely nothing, no new character, no new or higher combination of the vital elements; they can only take what is already given; they can only select and eliminate among the wealth of what is offered.(38) And the offerer is Life itself by virtue of its mysterious capacity for boundless and inexhaustible variability, self-enrichment and increase. The “struggle for existence” only digs the bed through which life’s stream flows, draws the guiding-line, and continually stimulates it to some fresh revelation of its wealth. But this wealth was there from the beginning; it was, to use the old word, “potential” in the living, and included with it in the universal being from which life was called forth. The struggle for existence is only the steel which strikes the spark from the flint; is, with its infinite forms and components, only the incredibly complex channel through which life forces its way upwards. If we keep this clearly in mind, the alarming and ominous element in the theory shrinks to half its dimensions.

And, finally, if we can rid ourselves of the peculiar fascination which this theory exercises, we soon begin to discover what extraordinary improbability and fundamental artificiality it implies. “Utility” is maintained to be that which absolutely, almost tyrannically, determines form and development in the realm of the living. Is this an idea that finds any analogy elsewhere in nature? Those who uphold the theory most strongly are wont to compare the development of organisms to crystal-formation in order in some way to tack on the living to the not-living. Crystal-formation, with its processes of movement and form-development, is, they say, a kind of connecting link between the living and the not-living. And in truth we find here, as in the realm of life, species-formation, development into individuals, stages and systems. But all this takes place without any hint of “struggle for existence,” of laboriously “selective” processes, or of ingenious accumulation of “variations.” The “species” of crystals are formed not according to utility, but according to inherent, determining laws of development, to which the diversity of their individual appearances is due. If “Life” were only a higher potential of what is already stirring in crystallisation, as this view suggests, then we should expect to find fixed tendencies, determined from within, in accordance with which life would pass through the cycle of its forms and possibilities, and rise spontaneously through gradual stages.
