Teleological and Scientific Interpretations are Alike Necessary.
(7.) Thus religion confidently subjects the world to a teleological interpretation. And to a teleological study in this sense the strictly causal interpretations of natural science are not hostile, but indispensable. For how do things stand? Natural science endeavours by persistent labour to comprehend the whole of the facts occurring in our world, up to the existence of man, as the final outcome and result of an age-long process of evolution, attempts also to follow this process ever higher up the ladder of strictly causal and strictly law-governed sequences, and finally to connect it with the primary and simplest fundamental facts of existence, beyond which it cannot go, and which must simply be accepted as ”given.” If these results of this causally interpreted evolution reveal themselves to our inward power of valuation as full of meaning and value, indeed of the deepest and most incomparable value, the causal mode of explanation is in no way affected, but its results are all at once placed in a new light and reveal a peculiarity which was previously not discoverable, yet which is their highest import.
They become a strictly united system of _means_. And purposefulness as a potentiality is thus carried back to the very foundation and ”beginning,”
to the fundamental conditions and primary factors of the cosmos itself.
The strict nexus of conditions and causes is thus nothing more than the ”endeavour after end and aim,” the carrying through and realisation of the eternal purpose, which was implicit potentially in the fundamental nature of things. The absolute obedience to law, and the inexorableness of chains of sequence are, instead of being fatal to this position, indispensable to it. When there is a purpose in view, it is only where the system of means is perfect, unbroken, and absolute, that the purpose can be realised, and therefore that intention can be inferred. In the inexplicable datum of the fundamental factors of the world's existence, in the strict nexus of causes, in the unfailing occurrence of the results which are determined by both these, and which reveal themselves to us as of value and purpose, teleology and providence are directly realised. The only a.s.sumptions are, that it is possible to judge the results according to their value, and that both the original nature of the world and the system of its causal sequences-that is, the world as we know it-can be conceived of in accordance with the ideas of dependence and conditionedness. Both a.s.sumptions are not only possible, but necessary.
In thinking out this most general consideration, we find the real and fundamental answer to the question as to the validity and freedom of the religious conception of the world with regard to teleology in nature. And if it be held fast and a.s.sociated with the insight into the autonomy of the spiritual and its underivability from the natural, we are freed at once from all the petty strife with the naturalistic doctrines of evolution, descent, and struggle for existence. We shall nevertheless be obliged to discuss these to some extent, because it is not a matter of indifference whether the detailed study of natural evolution fits in more or less easily with the conception of purpose whose validity we have demonstrated in general. If that proves to be the case, it will be an important factor in apologetics. The conclusion which we have already arrived at on abstract grounds will then be corroborated and emphasised in the concrete.
CHAPTER IV. DARWINISM IN GENERAL.
Darwinism, which was originally a technical theory of the biological schools, has long since become a veritable tangle of the most diverse problems and opinions, and seems to press hardly upon the religious conception of the world from many different sides. In its theory of blind ”natural selection” and the fortuitous play of the factors in the struggle for existence, it appears to surrender the whole of this wonderful world of life to the rough and ready grip of a process without method or plan.
In the general theory of evolution and the doctrine of the descent of even the highest from the lowest, it seems to take away all special dignity from the human mind and spirit, all the freedom and all the n.o.bility of pure reason and free will; it seems to reduce the higher products of religion, morality, poetry, and the aesthetic sense to the level of an ign.o.ble tumult of animal impulses, desires and sensations. Purely speculative questions relative to the evolution theory, psychological and metaphysical, logical and epistemological, ethical, aesthetic, and finally even historical and politico-economical questions have been drawn into the coil, and usually receive from the Darwinians an answer at once robust and self-a.s.sured. A zoological theory seems suddenly to have thrown light and intelligibility into the most diverse provinces of knowledge.
But in point of fact it can be shown that Darwinism has not really done this and cannot do it. It leaves unaffected the problem of the mind with its peculiar and underivable laws, from the logical to the ethical.
Whether it be right or wrong in its physiological theories, its genealogical trees and fortuitous factors, preoccupation with this theory is a task of the second order. Nevertheless it is necessary to study it, because the chief objections to the religious interpretation of the world have come from it.
The Development of Darwinism.
In studying it we should like to follow a method somewhat different from that usually observed in apologetic writings. ”Darwinism,” even in its technical, biological form, never was quite, and is to-day not at all a unified and consistent system. It has been modified in so many ways and presented in such different colours, that we must either refrain altogether from attempting to get into close quarters with it, or we must make ourselves acquainted to some extent with the phases of the theory as it has gradually developed up to the present day. This is the more necessary and useful since it is precisely within the circle of technical experts that revolts from and criticisms of the Darwinian theory have in recent years arisen; and these are so incisive, so varied, and so instructive, that through them we can adjust our standpoint in relation to the theory better than in any other way. And in thus letting the biologists speak for themselves, we are spared the fatal task of entering into the discussion of questions belonging to a region outside our own particular studies.
We cannot, however, give more than a short sketch. But even such a sketch may do more towards giving us a general knowledge of the question and showing us a way out of the difficulties it raises than any of the current ”refutations.” To supplement this sketch, and facilitate a thorough understanding of the problem, we shall give somewhat fuller references than are usual to the relevant literature. And the same method will be pursued in the following chapter, which deals with the mechanical theory of life. This method throws more upon the reader, but it is probably the most satisfactory one for the serious student.
The reactions from the Darwinism of the schools which we have just referred to, and to which the second half of this chapter is devoted, are, of course, of a purely scientific kind. And while we are devoting our attention to them, we must not be unfaithful to the canon laid down in the previous chapter, namely that with reference to the question of teleology in the religious sense no real answer can be looked for from scientific study, not even if it be anti-Darwinian. In this case, too, it is impossible to read the convictions and intuitions of the religious conception of the world out of a scientific study of nature: they precede it. But here, too, we may find some accessory support and indirect corroboration more or less strong and secure. This may be ill.u.s.trated by a single example. It will be shown that, on closer study, it is not impossible to subordinate even the apparently confused tangle of naturalistic factors of evolution which are summed up in the phrase ”struggle for existence” to interpretation from the religious point of view. But matters will be in quite a different position if the whole theory collapses, and instead of evolution and its paths being given over to confusion and chance, it appears that from the very beginning and at every point there is a predetermination of fixed and inevitable lines along and up which it must advance. In many other connections considerations of a like nature will reveal themselves to us in the course of our study.
Darwinism, as popularly understood, is the theory that ”men are descended from monkeys,” and in general that the higher forms of life are descended from the lower, and it is regarded as Darwin's epoch-making work and his chief merit-or fault according to the point of view-that he established the Theory of Descent. This is only half correct, and it leaves out the real point of Darwinism altogether. The Theory of Descent had its way prepared by the evolutionist ideas and the speculative nature-philosophy of Goethe, Sch.e.l.ling, Hegel and Oken; by the suggestions and glimmerings of the nature-mysticism of the romanticists; by the results of comparative anatomy and physiology; was already hinted at, at least as far as derivation of species was concerned, in the works of Linne himself; was worked out in the ”zoological philosophies,” by the elder Darwin, by Lamarck, Etienne Geoffrey St. Hilaire and Buffon; was in the field long before Charles Darwin's time; was already in active conflict with the antagonistic theory of the ”constancy of species,” and had its more or less decided adherents. Yet undoubtedly it was through and after Darwin that the theory grew so much more powerful and gained general acceptance.
Darwinism and Teleology.
But the essential and most characteristic importance of Darwin and his work, the reason for which he was called the Newton of biology, and which makes Darwinism at once interesting and dangerous to the religious conception of the world, is something quite special and new. It is its radical opposition to teleology. Du Bois-Reymond, in his witty lecture ”Darwin versus Galiani,”(4) explains the gist of the matter. ”Les des de la nature sont pipes” (nature's dice are loaded). Nature is almost always throwing aces. She brings forth not what is meaningless and purposeless, but in great preponderance what is full of meaning and purpose. What ”loaded” her dice like this? Even if the theory of descent be true, in what way does it directly help the purely scientific interpretation of the world? Would not this evolution from the lowest to the highest simply be a series of the most astonis.h.i.+ng lucky throws of the dice by which in perplexing ”endeavour after an aim,” the increasingly perfect, and ultimately the most perfect is produced? And, on the other hand, every individual organism, from the Amba up to the most complex vertebrate, is, in its structure, its form, its functions, a stupendous marvel of adaptation to its end and of co-ordination of the parts to the whole, and of the whole and its parts to the functions of the organism, the functions of nutrition, self-maintenance, reproduction, maintenance of the species, and so on. How account for the adaptiveness, both general and special, without _causae finales_, without intention and purposes, without guidance towards a conscious aim? How can it be explained as the necessary result solely of _causae efficientes_, of blindly working causes without a definite aim? Darwinism attempts to answer this question. And its answer is: ”What appears to us 'purposeful' and 'perfect' is in truth only the manifold adaptation of the forms of life to the conditions of their existence. And this adaptation is brought about solely by means of these conditions themselves. Without choice, without aim, without conscious purpose nature offers a wealth of possibilities. The conditions of existence act as a sieve. What chances to correspond to them maintains itself, gliding through the meshes of the sieve, what does not perishes.”
It is an old idea of the naturalistic philosophies, dating from Empedocles, which Darwin worked up into the theory of ”natural selection”
through ”the survival of the fittest” ”in the struggle for existence.” Of course the a.s.sumption necessary to his idea is that the forms of life are capable of variation, and of continually offering in ceaseless flux new properties and characters to the sieve of selection, and of being raised thereby from the originally h.o.m.ogeneous to the heterogeneous, from the simple to the complex, from the lower to the higher. This is the theory of descent, and it is, of course, an essential part and the very foundation of Darwin's theory. But it is _the doctrine of descent based upon natural selection_ that is Darwinism itself.
The Characteristic Features of Darwinism.
We do not propose to expound the Darwinian theory for the hundredth time; a knowledge of it must be taken for granted. We need only briefly call to mind the characteristic features and catchwords of the theory as Darwin founded it, which have also been the starting points of subsequent modifications and controversies.
