Part 16
While the _main_ direction of the inorganic has been towards degradation of energy, it has shown another subsidiary direction towards the production of more and more complex forms of matter. If our general ideas are correct, there must have been a time when matter in our ordinary sense of the word did not exist--there can have been no atoms, only free electrons. From this state, there evolved one in which the various electron-systems that we call atoms first appeared; later still, atoms could join with atoms to produce molecules. Leaping over vast periods, we would come to the time when radiation had brought the temperature of the earth surface below 100 degrees centigrade; water then could form from steam and solution occur. Through solution, all soluble elements, which would otherwise remain locked in the inactivity of the solid state, are enabled to enter upon a new phase of mobility, of chemical life, as we may say. Only in water could colloid carbon compounds first be built up, and only from such substances could life originate.
Living substance, or at least much of it, must be formed of molecules containing thousands of atoms, each atom in its turn a system of circling electrons. Here already is a vast increase of complexity: it remains to be seen whether the same tendency is perpetuated later.
The evolutionary concept is to biology what the doctrine of the conservation of energy has been in the physico-chemical sciences--an indispensable preliminary to proper methods of attack. But while great stress has been laid on the various _methods_ by which evolution may be supposed to have taken place--natural selection, Lamarckism, orthogenesis and the rest--biology has concerned herself comparatively little with the _form_ of the process in itself. But it is here that evolution becomes of value to us in our present search; for once more we become aware of a direction. Partly from the direct evidence of palaeontology, partly from indirect evidence, but along many converging lines, we can form an idea of this direction which in broad outlines is unassailable.
During life’s existence on earth--a period to be reckoned in hundreds and probably in thousands of millions of years--there has been an increase in various of its attributes. But just as in the inorganic world electrons and atoms still exist as such side by side with molecules, so also the earlier types of living matter continue to exist side by side with the later. The increase is not therefore seen uniformly in all forms at once, but is most easily observed by studying the _maximum_ level attained. Size, for instance, is one of these attributes; and whereas to-day all variations are to be found between ultra-microscopic disease-germs and vast organisms like whales and elephants, there has been a gradual steadying increase (tending to a limit) in the size of the _largest_ organisms existing at any one period.
If we confine ourselves for the moment to the material side, we find that the directional change in organic evolution can be reduced to this--to an increase of the control exercised by living matter over the environment, and of its independence of the environment--two reciprocal aspects of a single process. When we look more closely into the means by which this has been achieved, we shall see an increase of the maximum not only in size, but in complexity, in length of life, in efficiency of particular organs, in co-ordination of parts and general harmony, in improvement of sense-organs, and, continuing even after other tendencies have reached their limits, in brain-size and consequently in complexity of mode of reaction and behaviour.
If we turn to the psychological side, we find that there has been an increase in the intensity of mental process. This is apparent in all aspects of mind, on that of emotion equally with that of knowledge, of volition equally with that of emotion. To be an amoeba or a worm is to live a life almost without windows. Perfection of sense-organs makes it possible for life to be aware of the different types of outer events, whilst memory and, later, associative memory give the possibility of understanding their history. In higher forms volition can be maintained for longer and longer intervals, can attain greater intensity, and can fix itself upon ever more and more distant objects. With depth of feeling comes also differentiation, so that finally we find in ourselves the possibility of organizing various blends of the simple emotions into the compound emotional forms such as reverence and admiration, called _sentiments_ by McDougall.
Biologically speaking, therefore, the direction observable in mental evolution is again towards increased control and increased independence; by mental and cerebral improvement there is introduced a greater accuracy and a greater range of control, as well as better adjustment between organisms and environment, than would be otherwise possible to the same bodily organs.
The direction of life may therefore be roughly summed up in the two words “more life”--more both in quantity (have not both land and air been colonized during evolution?) and also in quality. More matter has been stolen from the lifeless and embodied in the living; and the living begins to be less helpless in face of the lifeless.
The direction of living matter is thus in many ways opposed to the direction to be seen in inorganic matter; yet not only has the organic arisen from the inorganic, but its direction continues one direction already traceable before the appearance of life.[46]
Finally, we come to the psychological aspect of the universe. We have already touched on it in connection with biology, and found that in many ways at least the development of mind follows the same lines as that of living matter, and helps forward the general trend of life.
But finally a kink occurs, a critical point similar to that seen at the origin of living from non-living matter. There the attributes of living matter which mark it off from inorganic matter become dominant--its capacity for self-reproduction, its tendency to organization. The colloid carbon compound had been the highest known independent unit; from now on this place was taken by the organism.
In exactly the same way, in the final stages of evolution (as witnessed abundantly by fossil mammals) complexity of purely bodily organization had reached a limit, and survival, as is evidenced by increasing size of brain, came to be determined more and more by mental qualities. Finally the curve of mental development caught up with that of body, and intersected it: mind became the dominant factor in the new type of organism, and in the subsequent history of the evolutionary process. The _organism_ ceased to be the highest unit, and gave place to the _person_, or self-conscious individual with organized mind.
This new critical point was reached when man arose; many authors recognize it for what it is, the beginning of a new era, by christening the subsequent geological period the Psychozoic. That period, geologically speaking, has not yet run but a tiny span; and we are no more entitled to think that we have reached or even imagined the possibilities of its future evolution than we should have been entitled to regard the possibilities of purely biological evolution as having been exhausted after the far longer period needed to give rise to a coral polyp or a jelly-fish as highest existing types of organism. Even man as a biological species is in his infancy, not to speak of other psychozoic types that may be waiting in the womb of time.
But what are the characteristics of this new phase? In the first place, mind has become self-conscious; thus the evolutionary methods of psychozoic organisms may become conscious, and they come to direct their own evolution instead of having their destinies shaped by the blind forces of natural selection.
In most respects the same direction as before is pursued, but new methods are introduced. The rate of change, of movement in that direction, is accelerated; and the possibility is given of eliminating a vast deal of waste. A watchmaker sends out very few defective watches: why? because he makes his watches on a preconceived plan. Even when an improvement in watch construction is introduced, he can draw up his plan beforehand, and at the worst, waste only time and paper, instead of metal and far more time. Ideas do not need to be embodied before selection can act upon them; thus an increasing amount of evolutionary change will take place through the natural selection of ideas than through the older and far more wasteful process, natural selection of individuals and species.
Finally, values appear upon the scene. If we could ask a wild animal such as a fox what gave value to its life, and it could answer us, it would doubtless say food, sleep, comfort, hunting, sexual pleasure, and family companionship. But it cannot answer; nor can it know the value of what it pursues, but only appreciate the result. Strictly speaking, values do not exist for it. However, even if we allow ourselves to speak of values in the life of pre-human organisms, we see immediately that wholly new values are introduced after the critical point.
Putting it summarily, we can say that, with the rise of mind to dominance, various activities of mind come to be pursued for their own sake, to have value in themselves. Our life is worth living not only for the sake of eating and drinking, sleeping, athletics, and sexual pleasure. There is a value attached to knowledge for its own sake, apart from the possible access of control that it may bring. But this is new, a property of man alone; not even Athena’s owl will exert itself through laborious years to understand celestial mechanics or physiology. The highest anthropoids do not attempt to create works of art, which for man come to have value in themselves. Natural beauty comes to have its value too; a cow (so far as known!) does not interrupt the business of its life to admire the sunset, whereas men may and do. Behaviour also is implicated; with the entry upon the scene of that practically unlimited number of possible reactions which give us what we call free will and choice, there comes a conviction that some modes of action are higher than others; and so a scale of moral values comes into being.[47]
Nor is it merely that values, in the strict sense, are created; nor that new values come into being. But with the enlargement of mind and its more perfect organization, there arises a new method of appraising values, and so a new type of value altogether. I mean of course the so-called _absolute values_. Absolute values are never absolute in the sense of absolute completeness; they are relative to two things--to external reality and to our mental powers and organization.[48] They are abstractions; we generalize the value in our minds, and at the same time raise it to the highest pitch of intensity we can. An interesting point arises from this way of thinking. Apart from the guarantee of our own convictions, the observable direction of living nature is our guarantee of right: or one had better say that it is at once the guarantee and the touchstone of our convictions. But two things may be moving in the same direction, and, if one be moving much slower than the other, the slower may impede the faster; a pedestrian procession making eastward along Fleet Street will hold up the life of the city for a time, and cows walking along railways are treated as obstacles by trains proceeding in the same direction. So it comes about that much that was once progressive in organic evolution has become an obstacle or a drag to psychozoic evolution; it is _relatively_ retrogressive, and, from our present standpoint, bad. To take the simplest and most fundamental example: evolution by blind natural selection was the method of progress for organisms below man. Unceasing struggle and courage was the chief factor in producing the grandeur and strength of the lion, the swiftness and grace of deer, the brilliance and lightness of the birds. But if the same end can be obtained both more quickly and more bloodlessly by new methods, then the old stands condemned. Here lies the key to the problem propounded by Huxley in his Romanes Lecture--the problem of man’s relation to the rest of the cosmic process, at once sprung from it by gradual generation and separated from it by an absolute and unbridgeable chasm, at once one with it and in deadly combat with it and all its ways.
Our mode of envisaging the problem illuminates it, and shows it as inevitable and intelligible instead of insoluble and tormenting; and illuminates too many other minor problems of good and evil. But all this is a side-issue: _revenons à nos moutons_.
Unknown, or neutral, or hostile power: a movement similar in direction to the direction in which history on the whole shows we are moving, and to that which we desire with our highest aspirations, but operating blindly; an acceleration of that movement by the coming of mind to biological predominance, with certain consequent minor changes in direction by major changes in speed and in methods. Three tendencies, but all founded in one unity, and each arising out of the other--that is the picture drawn for us by the present state of science. In this sense, and in this only, can it be said that “all things work together for righteousness.”
One word on an important side-issue--the problem of evil in man, of stagnancy and degeneration in organic evolution. Degeneration often does occur--a reversal, in other words, of the main tendency. But the positive fact remains that the _maximum_ level is progressively raised, and that we find that stagnation of development and even sometimes degeneration have been factors indirectly helping on the main direction.
We must accept the positive main direction for what it is--an external sanction of faith; confess that we do not understand the detailed working of the whole, but see in the change of methods brought about by the rise of mind a hope that we shall gradually learn at least to dispense with much waste and evil and degeneration in the further course of evolution.
This main direction gives us cause for optimism. The exceptions to it temper that optimism. But the direction is there.
As we shall see later, we may either call the sum of the forces acting in the cosmos the manifestations of God, who in this case must be the Absolute God, and unknowable except through these manifestations. Or we may confine the term God to its anthropological usage, as denoting the objects of human religion, in which case we must admit that the term God as understood by man is constituted by _man’s idea of_ the forces acting in the cosmos, so that not only are these forces involved, not only a possible Absolute God behind them, but also the organizing power of human mind.
I wish you here to agree to my adopting the second alternative and giving the name of God to the sum of the forces acting in the cosmos as perceived and grasped by human mind. We can therefore now say that God is one, but that though one, has several aspects. There is one aspect of God which is neutral to us, in a way hostile, mere Power operating in the vastness of the stellar universes, apprehended only as orderly, tending in a direction which appears to be in the long run inimical. It is to this aspect of God that Mr. Wells has given the name of the Veiled Being--a somewhat primitive term for a true idea. There is another aspect, which is the one seen operating in that sphere which comprises the whole of life upon this earth--a sphere infinitesimal in relation to the whole, yet still vast in relation to ourselves. This aspect of God is our refuge and guarantee, for here we find our assurance that our human life is a part of a whole that is not antagonistic, but moves in the same general direction as do our history and our aims. There does exist, in Matthew Arnold’s words, “a power, not ourselves, that makes for righteousness.” And this second aspect is not wholly separate from the first, in spite of its difference of direction; for the first is its parent, physically and temporally, and the direction of biological progress is the continuation of a line of development marked out, within the opposed inorganic direction, even from the first.
Next, there is a more immediate and more often demanded assurance that we, as individuals or as single communities in space or time, are at one with humanity as a whole. Here it is that we look to the third aspect of God, which enshrines the directive forces operating in man. These directive forces are our instincts, our needs, our values, our ideals. When those are harmonized with each other and with the outer world by reason and experience, they form a power which we can see has been directive, normative in the past, and will continue to be so in the future. It alters with man’s development; but after a first rudimentary phase, its main outlines, its type of organization remain the same, for man’s instincts and ideals do not greatly change, and their harmonization with each other and with experience will generally proceed in the same broad way. Although in a sense this aspect is the smallest, as comprising the smallest physical field, yet in another it is the largest, since man’s ideals are in themselves unlimited, non-finite; and the values involved, to our present type of mind, appear ultimate. This third aspect of God is again historically the offspring of the second, and through the second of the first.
Matter, life, mind--this is the simplest classification of phenomena. By means of processes analogous to obtaining a resultant by the parallelogram of forces, we can obtain a resultant of material operations in general, vital operations in general, and mental operations in general, numerous and varied in direction though they be. Life is the link between the other two. Living matter is so definitely one with non-living matter, not at all obviously one with mind; yet the direction of living matter is obviously similar to that of mind, not at all obviously one with that of non-living matter.

It is a simple fact that the conception which man has of the universe and its relation to himself exercises important effects upon his life. A name therefore is needed for this anthropological phenomenon. _God_ is the usual name applied, and we shall retain it in default of another, premissing that the word, like many similar general terms--“love,” or “life,” or “beauty,” say--can be defined and applied in many ways, and that we apply it here in a particular and perhaps somewhat novel sense.
God in this sense is the universe, not as such, but so far as grasped as a whole by a mind, embodied in an idea,[49] and in consequence capable of influencing that mind, and through it the whole course of events. It is not grasped as a mere sum of details, but, however vaguely and imperfectly, as a single idea, unitary in spite of its complexity. Nor is it the universe in itself, but only so far as it has been thus grasped by mind. There exists no other meaning of the term which, on analysis, is found to convey anything, or at least anything scientific or comprehensible, to us. We may reason that there is an Absolute God behind the universe and our idea of it. But we have no proof of this statement, and such an Absolute God is, as Spencer pointed out, an Unknowable, and accordingly no concern of ours. That part and these aspects of the universe which have been grasped by us may prove to contain the key to many of our difficulties; meanwhile we can only be humble and admit that our idea of God, even in this restricted sense, is still extremely incomplete: and in this sense there is a God far greater than our present idea and knowledge of God, only waiting to be discovered.
That which it is essential to establish is our way of looking at the problem. The universe does come into relation with our minds, and there, owing to the way it and our minds are organized, generates an idea which exerts an influence upon us.
The external basis of the idea of God is thus constituted by the forces operating in the universe. The universe is a unitary whole, greater and more powerful than ourselves, and its operations have resultants in certain main directions--these are phenomena which we constatate like any other phenomena. They, and that other phenomenon of our contact with the Universe and our exposure to the play of its forces, give us our objective knowledge of God. The rest of our idea of God, the inner component, depends upon the mode of action of our minds.
So far, then, we have shown that recent advance in science, particularly in our understanding of evolution, has enabled us to give a more objective account than ever before of what is involved in the concept _God_, and so to pave the way for a consensus of thought on the question.
It will be observed that there is no idea of personality implicit in this conception of God--God may or may not possess personality. It will be for us later to investigate that particular aspect of the problem.
It now remains to deal with the inner reality. Man has a wholly new type of mind. He is social and capable of speech. He generalizes, and he has a very highly developed power of association. This combination gives him a great many possibilities hitherto denied to life. In the first place, he is able to order his experiences in a totally new way, differing from the old very much as a classified card-index differs from a rough diary-record of events. The organization of his mind is elastic, capable of indefinite expansion and of specialization in any direction.
That being so, there will be always parts of his mind wholly or at least partially undeveloped; and in any case the capacities which he must employ in his everyday life, the region of his mind illuminated by the attention needed in the struggle for existence, constitute but a fraction of his mental self and its potentialities.
This brings us on to one of the most important achievements of modern psychology--the discovery and analysis of the subconscious. Impossible here to go into detail; we must content ourselves with a few broad statements. When we speak of the subconscious mind, we mean that in man there exist processes which appear for many reasons to be of the same nature as those of the normal mind (in that they are associated with the same parts of the nervous system, fulfil the same general biological functions, and probably operate through similar mechanisms), with the single exception that we are not conscious of them as such.[50]
The conscious mind, that which we think of as the basis of our mental individuality, as our personal being, is the result of a long process of organization. We come into the world with a set of instinctive and emotional reactions only waiting their proper stimuli to be fired off, with a capacity for learning, for amassing experience, and a capacity for modifying our instincts and our behaviour according to our experience. We incorporate experience in ourselves, and in so doing we alter the original basis of our reactions; a strongly emotional experience colours all that is closely associated with it; and so after birth we are continually making our mental microcosm not only larger but qualitatively more complex, in exactly the same way as before birth our body grew not only in size, but also in complexity of organization.
