III.
Assuming still that the facts collected and arranged by experimental science in favour of the hypothesis are such as to demand some kind of Evolution-philosophy; assuming that the very imperfect serial classification of living things according to their degree of organic definiteness, coherence, and heterogeneity not merely represents a variety which has always coexisted since life was possible on this earth, but rather traces out or hints at the genetic process by which this variety has been produced, let us see if there be any other governing principle directing the process, more intelligible than the persistence of that mere organic life which cannot even be thought of as distinct from those appliances and functions which it is supposed to have evolved for its own service by "natural selection."
Let us admit, what is really evident, that life is nothing distinct from the sum of those functions which minister to the preservation of life; and that therefore it is not the same thing in a man and in a mud-turtle. Man's superior faculties are not merely a more complicated machinery for producing an identical effect which the mud-turtle produces more simply and abundantly, but rather by their very play constitute an entirely different and higher kind of life. When Hume, in his Treatise on Human Nature, says: "Reason is and ought to be the slave of the passions and can never pretend to any other office than to serve and obey them," he implies that the exercise of reason is no constituent factor of human life, but something outside it, subordinate to it, whereas that life itself consists in passion, or pleasurable sensation, of which man, in virtue of his reason and other advantages, secures more than do his fellow-animals. This is just the conception of life which we have seen to be incoherent on close inspection; and if it be so, then the evolutionary process is a struggle not for bare life or existence, but for the prevalence of the higher kinds of life and existence; and intelligence and morality are not only co-operative as instruments in maintaining and extending human life, but are themselves the principal elements of that complex life. True, the mind does minister to the body and preserve it; but still more does the body minister to the mind; or rather, each ministers to that whole in which the play of the mind is the principal function and the play of the body subordinate. If, then, we hold to the verdict of our common sense, and regard our mental life not as subordinate to our sensitive and vegetal life, but as co-ordinate and even superior, we must (so to speak) view it as no less "for its own sake," as no less an "end in itself" than they are, but rather much more; we must regard evolution as making for the life of truth and the life of righteousness even more principally than for bare existence or animal vitality. It is now no longer mere life that tries to assert itself, and in the struggle shapes things to what they are; but it is the very highest kind of life, that is trying to come to the birth. Nature inherently tends to the higher through the lower forms of life, and these minister to the higher and receive in return from them the means of a yet more efficacious ministry.
In this conception, every function of the organism has two aspects, under one of which it is its own end and exists for its own sake as an element of the life of the whole; under the other it is ministerial, serving other functions above and below it, as it in return is served by them. Correspondence with the environment is, similarly, not merely a condition of life, but also that wherein vitality principally consists. "Living" is spontaneous self-adaptation to surrounding reality, taken in the very widest sense. The more diverse and multiform this adaptability, the fuller and higher is the life; and thus our ordinary common-sense classifications are justified. Each new manifestation of life means some new correspondence with surrounding reality as we piss from mere vegetation, and then add local movement, and one sense after another, till we come finally to intelligence and the life of reason and right-doing, which again, consists in self-conformation to things as they really are. In all this we are in agreement with common sense and common language, which identify the fullest life with the fullest activity; all activity being of the nature of response to stimulus, that is, correspondence to reality. As soon as consciousness supervenes on the lower forms of life it is evident that the pleasures of sight, hearing, taste, mind, and affection all depend on, and consist in, the consciousness of this successful accommodation of the subject to the object; and that all pain and disease is simply the felt failure of such adaptation. What was anciently and very wisely called the "natural appetite" of living creatures is in this view nothing else but their response to the modifying attraction exerted upon them by the objective Reality which presses upon them on every side, and tends to draw them into conformity with itself so far as they have latent capacity for such a correspondence. It is the light that makes (or rather elicits) sight; and it is sound that develops the sense of hearing: and it is the ideas embodied in Nature that call our intellect into play. Hence it follows that, desire for truth and justice, for society and for religion, which assert themselves as invariably in the soul of man at certain stages of progress, as the desire for mere life asserts itself from the first, is simply the felt result of the as yet unsuccessful endeavour of Nature to draw man into a fuller kind of correspondence with herself.
Thus conceived, the course of evolution is comparable, not as before, to the gradual unveiling of a blank canvas, revealing simply a greater extent of the same appearance, but to the gradual unveiling of a picture whose full unity of meaning is held in suspense till the disclosure is completed. We do not now interpret the higher by the lower, but the lower by the higher; the beginning by the end. This may seem perilously near to finalism, yet it is no more necessarily so, than the process of photography; we only need a self-adaptive tendency in life-matter responsive to the stimulating-tendency of the environment. Not, of course, that this bundle of words really explains anything, but that like other formulae of the kind, it prescinds from the question of ends and origins, by making a statement of what happens serve as a cause of what happens, and calling it a Law or a Tendency, or a Latent Potentiality—thus filling the gap which mere agnosticism creates in our thought.
With this conception of Evolution our ordinary estimates of "higher" and "lower" are saved; also the value of our mental processes upon which rests whatever proof the theory may admit of; while the "argument from adaptability" is provided with a firm basis independent of finality. All our "natural," as opposed to our personal and self-determined appetites or cravings,—those which are, so to say, constitutional and inseparable from our nature in certain conditions, are evidence of the influence of some reality outside us seeking to draw us into more perfect correspondence with itself, and whose nature can be more or less dimly conjectured from the nature of those cravings. What are called "natural religions" represent man's self-devised attempts to explain the reality answering to his religious and moral cravings. Revelation is but a divine interpretation of the same; as though one with dim vision were to supplement his defect by the testimony of another more clear-sighted.
It may be practically admitted that no philosophy allows of strict demonstration, since, being a conception of the totality of things, it modifies our understanding of every principle by which one might attempt to prove or disprove it. Eventually it is its harmony with the totality of things as we perceive them that determines us to accept it, and no two of us perceive just the same totality, however substantial an agreement there may be in our experience; yet I think it can hardly be denied that this conception of evolution is far more in agreement with the world as most of us know it, and commonly think and speak of it, than the former; that it not merely satisfies our intellect, but offers some satisfaction to our whole spiritual nature. "Is it certain," asks Mr. Bradley, in a fairly similar connection, "that the mere intellect can be self-satisfied if the other elements of our nature remain uncontented?" And, again: "A result, if it fails to satisfy our whole nature, comes short of perfection: and I could not rest tranquilly in a truth if I were compelled to regard it as hateful…. I should insist that the inquiry was not yet closed and that the result was but partial. And if metaphysics" [for which we may substitute: any philosophy, such a& that of Evolution] "is to stand, it must, I think, take account of all sides of our being. I do not mean that every one of our desires must be met by a promise of particular satisfaction; for that would be absurd and utterly impossible. But if the main tendencies of our nature do not reach consummation in the Absolute, we cannot believe that we have attained to perfection and truth."[7] From this point of view there can be no doubt as to which of these conceptions of Evolution is the more rational and satisfactory; that which would explain it by a simple tendency in living matter to persist and spread, and would see in all organic variety only the selected means to that somewhat colourless end; or that conception which would explain it by a tendency in living matter to come into ever fuller correspondence with its environment, seeing in such spontaneous correspondence the very essence of life, and not merely a condition of life.
We need only add a few criticisms on this second conception.
1. It is true that every creature struggles more intensely and vigorously for the lower kind of life, or for "mere life," as we might say, than for any of those things which alone would seem to make life worth the having. But this only means that to live at all is the most fundamental condition of living well and fully and enjoyably. The higher life cannot stand without the lower, which it includes, but the lower is not therefore the better, nor is it the end for whose sake the higher is desirable; but conversely. Not until men have got bread enough to eat will they have leisure or energy to spare for the animal grades of vitality. When the means of bodily subsistence grow scarce, then the faculties that were previously set free to seek the bread of a higher and fuller life are diverted to the struggle for bare animal existence, and progress is thrown back; but when there is abundance for all, secured by the labour of a few from whom the remainder can buy, then fuller life becomes once more possible for that remainder. The struggle for bodily food gives an advantage to, and "selects" naturally, those mental and other powers which facilitate its attainment; but just as man does not only eat and labour in order to live, but also (however it may shock conventional ethics) lives in order to eat and labour; so the new energies called forth by competition do not merely secure that grade of life in whose interests they are evoked and perfected, but extend the sphere of vitality, in so much as their own play adds a new element to life and gives it a new form.
The part played by struggle and competition in this process of Evolution is naturally exaggerated by those who deny any latent tendency other than that of mere persistence in being; who repudiate an internal expansiveness towards fuller kinds of existence, drawn out or checked by the environment.
Competition plays a prominent part when there is question of the lower grades of life, in so far as these depend on a pabulum that is limited in quantity. In such cases competition, within certain limits, will secure the bringing-out of latent powers by which the lower level of life is maintained and a higher level entered upon; the lower being secured by the superimposition of the higher.
But how does it do so? Not by creating anything, but by giving the victory to those individuals who already were ahead of their fellows in virtue of a fuller development of their nature from within; in clearing the ground for them and letting them increase and multiply.
2. Again, we should notice that development in one direction may be at the cost of development in another. The struggle for any lower form of existence than that already attained, is inevitably at the cost of the higher. The degrading effects of destitution are proverbial. Craft, cruelty, selfishness, and all the vices needed for success in a gladiatorial contest are often the fruits of such competition. Also, commercial progress seems on the whole to be at the expense of progress in art and the higher tastes, sacrificing everything to the production of the greatest possible quantity of material comforts. If it sharpens the wits and sensibilities in some directions, it blunts them in others.
Now, the first sense suggested to us in these days by the word "progress," is material progress—all that came in with steam; and this narrow conception vitiates much of our reasoning. It is in this realm undoubtedly that competition is such a factor of rapid advance; but we forget that the food of what the best men have ever considered the best life, is not limited or divisible; but like the light and air is undiminished how many soever share it. Whatever advance there has been in the life of the mind and of the higher tastes and sensibilities, cannot directly be explained by competition, but simply by the quiet upward working of Nature's inherent forces. We look with scorn at the unprogressive East, satisfied that there can be no progress, no life worth living, where there is no rush for dollars. But I think we have yet to learn the meaning of ex Oriente lux.
Much of our immorality and our social evil comes from the fact that those who have developed the faculties of a higher grade of life, seek the lower as an end in itself, and not simply so far as it is a condition of the higher and no further. The Gospel precept, as usual, enunciates only the law of reason and nature, when it bids us to "Seek first the Kingdom of God and its justice," that is, to put our best life in the front, and to make it the measure and limit of any other quest. The neglect of this principle gives us high living and plain thinking, instead of "high thinking and plain living;" and takes the bread out of the mouths of the poor. The competition for pleasures and luxuries and amusements, may indeed develop certain industries and cause progress in certain narrow lines, but it is at the cost of the only progress worth the name.
The conflict between this "struggle-theory" and ethics has been freely acknowledged by Professor Huxley and others; every attempt to educe unselfishness from selfishness has failed. The moral man even in our day has rather a bad time of it; what chance would he have had of surviving to propagate his species in the supposed pre-moral states of human society? Who can possibly conceive mere rottenness being cured by progress in rottenness; or a man drinking himself into temperance? On the other hand, it is at least conceivable that in the wildest savage there is some little seed of a moral sense—weak, compared with the lowest springs of action, just because it is the highest and therefore only struggling into being; and that in the slow lapse of time events may here and there prove that honesty is the best policy; and that honesty once tasted may be found not only useful for other things, but agreeable for itself, and may be cherished and strengthened by social and religious sanctions.
There is, however, a reaction on foot which tends to reconcile the breach between ethics and evolution, by reducing the part played by competition within reasonable bounds, and making it subservient to the survival, not of the most selfish, but of the most social individuals. Definite variations from within, modified between narrow limits by accidental variation from without, is coming to be acknowledged as the chief factor of progress. But we should not forget that to allow an internal principle of orderly development is, not merely to modify the popular evolution theory by a slight concession to its adversaries; it is rather to make it no longer the supreme explanation of development, but at most a slight modification of the more mysterious theory which it was its boast and merit to have supplanted. According to Geddes and Foster and others of their school, it is the species-subserving qualities that Nature selects; and these, in the higher grades of life, are equivalent to the altruistic, social, and ethical qualities. It is in virtue of the parental and maternal instincts of self-sacrifice, self-diffusion, self-forgetfulness in the interests of the offspring, that species are preserved and prevail. Selfish egoism leads eventually (as we see in some modern countries where laizzez-faire liberalism prevails) to social disruption, decadence, and chaos; and this is the universal law of life in every grade. At first indeed the unit struggles to live, for life is the condition of propagation; but the root of this instinct is altruistic; it is the whole asserting itself in the part; and all "self-regarding" instincts are to be likewise explained as subordinate to the "other-regarding" instincts. As soon as this sub-ordination is ignored in practice, regress takes the place of progress. The transit, we are told, from the unicellular to the multicellular organism cannot be explained by individualism, but implies a diminution of the competitive, an increase of the social and subordinative tendency. The argument from economics to biology and back again, is said to be nearing exposure; the "progress of the species through the internecine struggle of its individuals at the margin of subsistence," is the outgoing idea. Yes, and with it goes out all that made Evolution a simple and therefore popular explanation of the world; and there comes in that "organic" conception of the process which clamours for theism and finalism as its only coherent complement.
3. But though Evolution so conceived makes the "argument from adaptability," as well as the arguments for theism, stronger rather than weaker; we must not shut our eyes to the difficulty created by the fact (too little insisted upon by Evolutionists) that there is no solid reason for thinking that progress is all-pervading. We have already said that progress in commerce may be regress in art or in religion or in morality. Also, progress in benevolence may co-exist with regress in fortitude and purity; progress in one point of morality with regress in another; progress in ethical judgment with regress in ethical practice. And in every realm, growth and decay, life and death, seem so to intertwine and oscillate that it is very gratuitous to designate the total process as being one or the other. Spencer confesses that the entire universe oscillates between extremes of integration and disintegration. Why we should consider the universe at present to be rising rather than falling, waxing rather than waning, one cannot say. The easier presumption is that it is equally one and the other, and always has been. Even were we rash enough to pronounce progress to be on the whole prevalent within the narrow field of our own experience, surely it were nothing but the inevitable "provincialism" of the human mind to pass per saltum from that, to a generalization for all possible experience. Our optimism, our faith that right, truth, and order will eventually prevail, can find only a delusive basis in actual experience, and must draw its life from some deeper source.
Why then should we so presume that our moral and religious ideas are really progressive and not regressive, as to regard their interpretation as approximating to the truth? The answer is simply that our argument from adaptability does not require the assumption in question, but only that we should be able to distinguish higher from lower tendencies, progressive from regressive movements, without holding the optimistic view that on the whole the forward tendency is at present prevailing. It is not because we live in the nineteenth century that we consider our moral perceptions truer than those of the ancient Hebrews, but because we at once comprehend and transcend their ideas (in some respects), as the greater does the less. In many points surely the relation is inverted and we feel ourselves transcended (or may at least suspect it), by those who lived or live in ruder conditions than our own. David has perhaps taught us more than we could have taught him; and there are other vices than those proper to semi-barbarism. It is not by reference to date or country, or grade of material progress, that we assess the value of moral judgments, but by that subjective standard with which our own moral attainments supply us in regard to all that is equal or less, similar or dissimilar. To deny this discernment is to throw the doors open to unqualified scepticism; to admit it, is all that we need for the validity of our inference.
4. If Evolution is really of this oscillatory character; if at all times much the same processes have been going on in different parts of this universe as now—one system decaying as another is coming into being; is it not more reasonable to imagine (for it is only a question of imagining) that the primordial datum was not uniform nebula, but matter in all stages of elaboration from the highest to the lowest—the same sort of result as we should get from a cross-section at any subsequent moment in the process? What reason is there for assuming primordial homogeneity, since every backward step would show us, together with the unravelling of what is now in process of weaving, a counter-balancing weaving of what is now in process of disintegration? Were this earth all, we might dream of universal advance by shutting our eyes to a great many incompatible facts; but when our telescopes show us the co-existence of integration and disintegration everywhere, what can we conclude but that in the past as in the future, no alteration is to be looked for beyond the shifting of the waves' crest from side to side of the sea of matter—the total ratio of depressions to elevations remaining exactly constant.
Were the other view of an original universal homogeneity correct, how conies it that we have still co-existent every stage of advance from the lowest to the highest, and that there is not a greater equality?—a difficulty which does not exist if we suppose things to have been on the whole, as they are now, from the very first. But whichever view we take; whether we suppose all things collectively to oscillate between recurring extremes of "sameness" and "otherness;" or every stage of the wave of progress from crest to trough, to be simultaneously manifested in the universe at all times, the old difficulty of "the beginning" will force itself upon us. A process ab aeterno is at least as unimaginable as the process of creation ex nihilo; if it be not altogether inconceivable to boot. And the alternative is, either a primordial state of homogeneous matter which contains the present cosmos in germ, and from which it is evolved without the aid of any environment—such a germ claiming a designer as much as any ready-made perfect world; or else, a primordial state of things like that which we should get at any cross-section of the secular process, in which every stage of life and death, growth and decay, evolution and involution, is represented as now. This would include fossils and remains of past civilizations which (in the hypothesis) would never have existed; and would be in all respects as difficult as the crudest conception of the creation-hypothesis. And if this absurdity drives us back to primordial homogeneity, as before, we must remember that here, too, though not so evidently, we should have all the signs of an antecedent process that was non-existent. Life and death, corruption and integration, are parts of one undulatory process. Cut the wave where you will its curve claims to be finished in both directions and suggests a before as well as an after. If, in the very nature of things, the pendulum sways between confusion and order, chaos and cosmos, each extreme intrinsically demands the other, not only as its consequent, but as its antecedent; and the first chaos, no less than any succeeding one, will seem the ruin of a previous cosmos. Therefore we are driven back upon a process ab aeterno with every stage of evolution always simultaneously represented in one part or other of the whole. Whatever mitigation such a conception may offer, surely we may be excused for still adhering to that simpler explanation which involves a mystery indeed, but nothing so positively unthinkable as a process without a beginning.
5. This same conception of a process without beginning, favours the notion that since life was possible on our globe all species may well have co-existed in varying proportions. From the sudden spread of population through almost accidental conditions, we can imagine how certain species might have been so scarce as to leave no trace in geological strata, whereas those which enormously preponderated at the same time would have done so. A change of conditions might easily cause the former to preponderate, and their sudden appearance in the strata would look as though they had then first come into being. In a word, we can have good evidence for the extinction of species, but scarcely any for their origination.
This supposition is not adverse to the derivation of species from a common stock, but rather favours the notion that as in the case of the individual the period of plasticity is short compared with that of morphological stability, so if there was such an arboreal branching out of species from a common root, it took place rapidly in conditions as different from ours as those of uterine from extra-uterine life; and that the stage of inflexibility may have been reached before any time of which we have record.
But in truth when we see in the world of chemical substances an altogether similar sedation of species where there can be no question of common descent as its cause, we may well suspend our judgment till the established facts have excluded the many hypotheses other than Evolution by which they may be explained.
As long as Evolution claims to be no more than a working scientific hypothesis, like ether or electric fluid—a sort of frame or subjective category into which observed facts are more conveniently fitted, it cannot justly be pressed for a solution of ultimate problems; but when it claims to be a complete philosophy and as such to extrude other philosophies previously in possession, it must show that it can rest the mind where they leave it restless; or that it has proved their proffered solutions spurious. This, so far, it has absolutely failed to do. At most it may determine more accurately the way in which God works out His Idea in Creation. It can stand as long as it is content to prescind from the question of ends and origins; but then it is no longer a complete philosophy. As soon as it attempts to solve those problems it becomes incoherent and unthinkable. Its true complement is theism and finality, which flow from it as naturally, if not quite so immediately as the "argument from adaptability." Deus creavit is so far the only moderately intelligible, or at least not demonstrably unintelligible, answer given to the problem of In principio.
We have then in this second and soberer form of the philosophy of Evolution, an attempt to explain the order of the universe without explicit recourse to the hypothesis of an intelligent authorship and government of the world: that is to say, independently of theism and finality; and so far as this explanation admits all the effects and consequences of an intelligent government, without ascribing them to that cause, it admits among their number the value of the "argument from adaptability," and allows us to infer that the postulates of man's higher moral needs correspond approximately to reality, of which they are in some sense the product; and that the "wish to believe" is less likely to be a source of delusion in proportion as the belief in question is higher in the moral scale.
But it is also clear how unsuccessful this attempted philosophy is in many ways; and with what difficulties and mysteries it is burdened. At best it can prescind from finalism by a confession of incompleteness and philosophical bankruptcy; by resolutely refusing to face the problem of the whole—of the ultimate whence and whither. If it would positively exclude theism or finalism it must ascribe all seeming order and adaptation to the persistence of some blind force, subduing all things to itself, to "existence," or to "life" striving to assert and extend itself. It is this conception that seems best to bring the mystery of the universe within the comprehension of the popular mind, and is more in keeping with those "aggregation theories" of our day which regard dust as the one eternal reality whose combination and disguises delude us into believing in soul and intelligence and divinity. But on closer examination the words "life" and "existence" answer to no simple reality or force which can be regarded as governing nature, and from this radical fallacy of language a whole brood of further absurdities spring up which make the popular form of Evolution-philosophy utterly incoherent.
