Broadly, two methods are adopted. In the one case we are presented with the order of the world, or the course of evolution, as indicative of a beneficent scheme. This claims to freely adopt all that science has to say concerning the development of life and to prove that this is in harmony with the legitimate demands of the moral sense. The second is the more orthodox way, and taking the world as it is, claims that pain and suffering play a disciplinary and educational part in the life of the individual. We will take these in the order named.

When dealing with the argument from design little was said concerning the evolutionary explanation of the special adaptations that meet us in the animal world. It was thought better to fix attention on the purely logical value of the argument presented. It is now necessary to look a little closer at the ethical implications of the evolutionary process.

It has been pointed out that all life involves a special degree of adaptation between an organism and its environment. Destroy that adjustment and life ceases to exist. How is that adjustment secured? The answer of the pre-Darwinian was that it represented a deliberate design on the part of God. Against this Darwinism propounds a theory of automatic or mechanical adjustment which makes the calling in of deity altogether gratuitous. And it remains gratuitous, no matter how far the scope of the theory of natural selection may be modified. But given the continuous variations which we know to exist with all kinds of life, given any sort of competition between animals as to which shall live, given even a degree of adaptation below which an animal cannot fall and live, and it is at once plain that the better adaptations will live and the poorer adapted will be eliminated. This process is analogous to that by which man has managed to breed so many varieties of domesticated animals and plants, some of the varieties presenting so marked a difference from the original type that if found in a state of nature they would often be classed as a distinct species. Man selects the variation that pleases him, eliminates or segregates the type that does not, and by following up the process eventually produces a distinct and fixed variation. It was because of the likeness of what goes on in the case of the breeder to what we see actually going on in nature that Darwin used the phrase "Natural Selection" as descriptive of the process. It was not an exact phrase, and it was not meant to be exact. For one thing—a very important thing, while a breeder selects, nature eliminates. Man's action, in relation to the type preserved, is positive. Nature's attitude in relation to the type preserved is negative. This is a very important distinction; and it is one that is fatal to the claims of theism. For if it points to a plan in nature it points to one that aims at killing off all that can be killed, and only sparing those who are able to protect themselves against its attack. And one is left wondering at the type of mind which can see goodness and wisdom in a plan that goes, on generation, after generation manufacturing an inferior or defective type in enormous numbers in order that a few superior specimens may be found, these in their turn to become inferior by the arrival of some other specimens a little more fortunate in their endowment. One hardly knows at which to marvel the most—at the clumsiness of the plan, or at the brutality of the design.

It was soon realised that the old argument from design was no longer possible. But if one can only get far enough away from the possibility of proof or disproof there is always a chance for the Goddite. So it was argued that inasmuch as natural selection meant the emergence of a "higher" type, and as there was no room for design within the process, might not the process itself be an expression of design? There might still be room for what Huxley, with one of those foolish concessions to established opinion which is the bane of English thought, called the "wider teleology." This was a teleology which placed a designing mind at the back of the evolutionary process, and arranging it with a view to a preconceived end. The process then becomes, to use Spencer's phrase, a "beneficent" one, since it eliminates the poorer specimens and leaves the better ones to perpetuate the species. We are thus asked to imagine a divine wisdom selecting the better and destroying the inferior much as an omniscient Eugenist might destroy at birth all human beings of an undesirable type.

The weakness of the thesis lies primarily in the fact that in the case of the breeder he has to take the animal as he finds it, subject to the play of forces, the characteristics of which are determined for him. He has to make the best of the situation. In the case of the deity he creates the animals with which he is assumed to be experimenting, he creates the forces with all their qualities, and thus determines the nature of the situation. Quite certainly no breeder would waste his time in breeding over a number of generations if he could secure the desired type at once. The whole of the argument of the advocate of the wider teleology is that God wanted the higher type. But if that is so why did he not produce it at once? What useful purpose could be served by producing at the end of a lengthy and murderous process what might just as well have been secured at the beginning? It is not wisdom but unadulterated stupidity to take thousands of years securing what might have been as well done in the twinkling of an eye.

There is, in short, no justification in the creation of a process so long as the end at which the process is aiming can be reached by a less tortuous method. As Mr. F. C. S. Schiller says:—

So long as we are dealing with finite factors, the function of pain and the nature of evil can be more or less understood, but as soon as it is supposed to display the working of an infinite power everything becomes wholly unintelligible. We can no longer console ourselves with the hope that "good becomes the final goal of ill," we can no longer fancy that imperfection serves any secondary purpose in the economy of the universe. A process by which evil becomes good is unintelligible as the action of a truly infinite power which can attain its end without a process; it is absurd to ascribe imperfection as a secondary result to a power which can attain all its aims without evil. Hence the world process, and the intelligent purpose we fancy we detect in it must be illusory.... God can have no purpose, and the world cannot be in process.... If the world is the product of an infinite power it is utterly unknowable, because its process and its nature would be alike unnecessary and unaccountable. (Riddles of the Sphinx; pp. 318-19).

Besides, as I have already pointed out, in the process as it meets us in nature there is not a selection for preservation, but a selection for killing. With the breeder preservation is primary. It is of no value to him to kill, it is the preservation of a desired type that is all important. In nature, so far as we can see, the whole aim is to destroy. It is not the fittest that are preserved so much as it is the unfittest that are killed. The fittest are left alive for no other apparent reason than that nature is unable to kill them. The truth of this is seen in the fact that where there is no death there is no evolution of a "higher" type. In the case of diseases that kill there is a gradual development of an immune type—which introduces the paradox that the healthiest diseases from which a race may suffer are those that are most deadly. Where a disease does not kill there is no development against it. It is the winnowing fan of death that makes for the development of animal life. And the correct picture of nature—if we must picture an intelligence behind it—would be that of an intelligence aiming at killing all, and only failing in its purpose because the natural endowment of some placed them beyond its power.

And, without examining the question begging word "higher," it may be said that natural selection does not make for the uniform covering of the earth with representatives of higher types. If in some parts of the world the higher have replaced the lower types, elsewhere the lower have replaced the higher. Natural selection, in fact, works without reference to whether the form which survives is "higher" or "lower." All that matters is adaptation. The germ of malaria renders whole tracts of the earth uninhabitable to those whom we consider representative of the higher culture. In other parts an alteration of the rainfall may crush out a civilisation, and leave a handful of nomadic tribes as the sole denizens of lands where once a lofty civilisation flourished. Throughout the whole of nature there is never the slightest indication that forces operate with the slightest reference to what we are accustomed to consider the higher interests of the race.

Moreover, from the standpoint of an apologetic theism, we are entitled to ask precisely what is meant by this justification of the evolutionary process in terms of the production of a higher type. The justification of a painful or a costly experience by an individual is two-fold. First, it is the only way, perhaps, in which certain things may be learned or accomplished, and, second, it is the individual who passes through the experience who benefits thereby. But suppose a person entered on a course of training with the absolute certainty that he would never survive it. Should we be justified in forcing the course on him? Clearly not. The whole would be regarded as a wasted effort and as an exhibition of gratuitous cruelty.
