But this kind of reduction to simpler terms only becomes “explanation” when these simpler terms are themselves clear and intelligible and not merely simple; that is to say, when we can immediately see why the simpler process occurs, and by what means it is brought about, when the question as to the “why” is no longer necessary, because, on becoming aware of the process, we immediately and directly perceive that it is a matter of course, indisputable, and requiring no proof. If this is not the case, the reduction to simpler terms has been misleading. We have only replaced one unintelligibility by another, one description by another, and so simply pushed back the whole problem. Naturalism supposes that by this gradual pushing back the task will at least become more and more simple, until at last a point is reached where the riddle will solve [pg 048] itself, because description becomes equivalent to explanation. This final stage is supposed to be found in the forces of attraction and repulsion, with which the smallest similar particles of matter are equipped. Out of the endlessly varied correlations of these there arise all higher forms of energy and all the combinations which make up more complex phenomena.

But in reality this does not help us at all. For now we are definitely brought face to face with the quite unanswerable question, How, from all this homogeneity and unity of the ultimate particles and forces, can we account for the beginnings of the diversity which is so marked a characteristic of this world? Whence came the causes of the syntheses to higher unities, the reasons for the combination into higher resultants of energy?

But even apart from that, it is quite obvious that we have not yet reached the ultimate point. For can “attraction,” influence at a distance, vis a fronte, be considered as a fact which is in itself clear? Is it not rather the most puzzling fundamental riddle we can be called upon to explain? Assuredly. And therefore the attempt is made to penetrate still deeper to the ultimate point, the last possible reduction to simpler terms, by referring all actual “forces” and reducing all movement, and therewith all “action,” to terms of attraction and repulsion, which are free from anything mysterious, whose mode of working can be unambiguously and plainly set forth in the law of the parallelogram of forces. Law? Set forth? Therefore still [pg 049] only description? Certainly only description, not explanation in the least. Even assuming that it is true, instead of a mere Utopia, that all the secrets and riddles of nature can be traced back to matter moved by attraction and repulsion according to the simplest laws of these, they would still only be summed up into a great general riddle, which is only the more colossal because it is able to embrace all others within itself. For attraction and repulsion, the transference of motion, and the combination of motion according to the law of the parallelogram of forces—all this is merely description of processes whose inner causes we do not understand, which appear simple, and are so, but are nevertheless not self-evident or to be taken as a matter of course; they are not in themselves intelligible, but form an absolute “world-riddle.” From the very root of things there gazes at us the same Sphinx which we had apparently driven from the foreground.

But furthermore, this reduction to simpler terms is an impossible and never-ending task. There is fresh confusion at every step. In reducing to simpler terms, it is often forgotten that the principle of combination is not inherent in the more simple, and cannot be “reduced.” Or else there is an ignoring of the fact that a transition has been made, not from resultants to components, but to quite a different kind of phenomena. Innumerable as are the possible reductions to simpler terms, and mistaken as it would be to remain prematurely at the level of description, it cannot be denied [pg 050] that the fundamental facts of the world are pure facts which must simply be accepted where they occur, indisputable, inexplicable, impenetrable, the “whence” and the “how” of their existence quite uncomprehended. And this is especially true of every new and peculiar expression of what we call energy and energies. Gravitation cannot be reduced to terms of attraction and repulsion, nor action at a distance to action at close quarters; it might, indeed, be shown that repulsion in its turn presupposes attraction before it can become possible; the “energies” of ponderable matter cannot be reduced to the “ether” and its processes of motion, nor the complex play of the chemical affinities to the attraction of masses in general or to gravity. And thus the series ascends throughout the spheres of nature up to the mysterious directive energies in the crystal, and to the underivable phenomena of movement in the living substance, perhaps even to the functions of will-power. All these can be discovered, but not really understood. They can be described, but not explained. And we are absolutely ignorant as to why they should have emerged from the depth of nature, what that depth really is, or what still remains hidden in her mysterious lap. Neither what nature reveals to us nor what it conceals from us is in any true sense “comprehended,” and we flatter ourselves that we understand her secrets when we have only become accustomed to them. If we try to break the power of this accustomedness and to [pg 051] consider the actual relations of things there dawns in us a feeling already awakened by direct impressions and experience; the feeling of the mysterious and enigmatical, of the abyssmal depths beneath, and of what lies far above our comprehension, alike in regard to our own existence and every other. The world is at no point self-explanatory, but at all points marvellous. Its laws are only formulated riddles.

Evolution and New Beginnings.

All this throws an important light upon two subjects which are relevant in this connection, but which cannot here be exhaustively dealt with,—evolution and new beginnings. Let us consider, for instance, the marvellous range and diversity of the characteristic chemical properties and interrelations of substances. Each one of them, contrasted with the preceding lower forms and stages of “energy,” contrasted with mere attraction, repulsion, gravitation, is something absolutely new, a new interpolation (of course not in regard to time but to grade), a phenomenon which cannot be “explained” by what has gone before. It simply occurs, and we find it in its own time and place. We may call this new emergence “evolution,” and we may use this term in connection with every new stage higher than those preceding it. But it is not evolution in a crude and quantitative sense, according to which the “more highly evolved” is nothing more than an [pg 052] addition and combination of what was already there; it is evolution in the old sense of the word, according to which the more developed is a higher analogue of the less developed, but is in its own way as independent, as much a new beginning as each of the antecedent stages, and therefore in the strict sense neither derivable from them nor reducible to them.

It must be noted that in this sense evolution and new beginnings are already present at a very early stage in nature and are part of its essence. We must bear this in mind if we are rightly to understand the subtler processes in nature which we find emerging at a higher level. It is illusory to suppose that it is a “natural” assumption to “derive” the living from lower processes in nature. The non-living and the inorganic are also underivable as to their individual stages, and the leap from the inorganic to the organic is simply much greater than that from attraction in general to chemical affinity. As a matter of fact, the first occurrence—undoubtedly controlled and conditioned by internal necessity—of crystallisation, or of life, or of sensation has just the same marvellousness as everything individual and everything new in any ascending series in nature. In short, every new beginning has the same marvel.

Perhaps this consideration goes still deeper, throwing light upon or suggesting the proper basis for a study of the domain of mind and of history. It is immediately obvious that there, at any rate, we enter into a [pg 053] region of phenomena which cannot be derived from anything antecedent, or reduced to anything lower. It must be one of the chief tasks of naturalism to explain away these facts, and to maintain the sway of “evolution,” not in our sense but in its own, that is “to explain” everything new and individual from that which precedes it. But the assertion that this can be done is here doubly false. For, in the first place, it cannot be proved that methods of study which are relatively valid for natural phenomena are applicable also to those of the mind. And in the second place we must admit that even in nature—apart from mind—we have to do with new beginnings which are underivable from their antecedents.

All being is inscrutable mystery as a whole, and from its very foundations upwards through each successively higher stage of its evolution, in an increasing degree, until it reaches a climax in the incomprehensibility of individuality. It is a mystery that does not force itself into nature as supernatural or miraculous, but is fundamentally implicit in it, a mystery that in its unfolding assuredly follows the strictest law, the most inviolable rules, whether in the chemical affinities a higher grade of energies reveals itself, or whether—unquestionably also in obedience to everlasting law—the physical and chemical conditions admit of the occurrence of life, or whether in his own time and place a genius arises.[1]
