To the savage, all is spirit. The meanest objects are charged with influence, the commonest actions fraught with spiritual possibilities, the operations of nature one and all are brought about by spiritual powers--but powers multifarious and conflicting. “Nature can have little unity for savages. It is a Walpurgis-nacht procession, a checkered play of light and shadow, a medley of impish and elfish, friendly and inimical powers.”[44]

But with ordered civilization and dispassionate observation a network of material cause and effect invaded this spiritual domain. The mysterious influences, for example, believed to be inherent in springs and running rivers became personified, and, anthropomorphized as nymphs or gods, were removed into a seclusion more remote from practical and everyday life than their unpersonified predecessors. Later, they retreated still farther from actuality into a half-believed mythology, and then passed away into the powerlessness of avowed fairy-story or literary symbolism, while the rivers, perceived as the resultant of natural forces, were more and more harnessed to man’s use. So with the wind and the rain, the growth of crops, the storms of the sea. So, in due time, with the thunder and the lightning, with earthquakes, eruptions, comets, eclipses, pestilences.

This process of liberating matter from arbitrary and mysterious power, of perceiving it as orderly and endowed with regularity of natural law, of bringing it more and more beneath human control, was, on the other hand, accompanied by what may be called a combined condensation and sublimation of the spiritual forces accepted by human faith. They are built up from spirit to spirits, spirits to gods, gods to God. But now it seems as if this condensation had reached its limit, and the sublimation could only go farther by resolving the one God into an empty name or the vaguest unreality.

We look back and see the Gods of early man, and are complacently prepared to believe that they were based in error, products of mental immaturity, to be relegated to limbo without regret. But what about the present? Why should we shrink from applying the same process to the God of to-day?

Is it then to be so with every God? Is God only a personified symbol of our residuum of ignorance? Is to hold the idea of God in any form to be, as Salomon Reinach believes, in an infantile stage of human development, and must we with him define religion as “a sum of beliefs impeding the free use of human faculty”?

I think not; and I shall endeavour to justify my belief to you, and to show that, albeit much alteration and a thorough revision of ideas is needed, the term _God_ has an important scientific connotation, and further that the present stagnation of religion can be remedied if, as has happened again and again in biological evolution, the old forms become extinct or subordinate, and a new dominant type is developed along quite fresh lines.

In any case the man of science must obviously, if he face the problem at all, take up a scientific attitude of mind towards it. He cannot say that there is no such thing as religion; or try to whittle it away by explaining that it is something else--a complicated fear, or a sublimated sex-instinct, or a combination of credulity and duplicity. A thing, if it is a thing at all, is never merely something else. Nor can he submit to the pretensions of those who assert that it is too sacred to be touched, or that its certainties are greater than those of science. No--he must treat it for what it is--a fact, and a very important fact at that, in human history: and he must see whether the application of scientific method to its study--in other words, its illumination by the faculty of pure intellect--will help not only our comprehension of religion in the past, but its actual development in the future.

He can study it in various ways. He can use the method of observation and comparison, collecting and collating facts until he is able to give a connected account of the manifestations of religion and of their past history; he can study it physiologically, so to speak, to see what part it plays in the body politic, and how that part may alter with circumstances; or he may seek to investigate its essence, to discover not only how it appears and what it does, but what it _is_.

Further, he must have some general principles to lean on in his search, principles both positive and negative. He must be content to leave certain possibilities out of account because as yet he cannot see how they can be connected with his organized scheme of things; in other words, he has to be content to build slowly and imperfectly in order that he may be sure of building soundly. This is the principle which we may call positive agnosticism.

This very fact has been in the past one of the great obstacles in the way of successful treatment of religion by science. One of the attributes of man is his desire for a complete explanation, or at least a complete view, of his universe, and this has been at the bottom of much doctrine and many creeds. But before Kepler and Newton, no truly scientific account could be given of celestial phenomena; before Darwin, none of Natural History; before the recent revival in psychology, none of the mind and its workings. In the second half of the nineteenth century, for instance, science could give an adequate account of most inorganic phenomena, and, in broad outline, of evolutionary geology and biology; but mind was still refractory. Accordingly, the philosophy of science was mainly materialist. But the common man felt that mind was not the empty epiphenomenon that orthodox science would have it; and he desired a scheme of things in which mind should be more adequately explained than it could be by science at its then stage of development. _Hinc illae lacrimae._

To-day it is at least possible to link up, not only physics and chemistry and geology and evolutionary biology, but also anthropology and psychology, into a whole which, though far from complete, is at least organized and coherent with itself. If the seventeenth century cleared the ground for that dwelling-place of human mind which we call the scientific view of things, if the eighteenth century laid the foundations and the nineteenth built the walls, the twentieth is already fitting up some of the rooms for actual habitation.

There are certain other domains of reality which have not yet been properly investigated by science. Telepathy, for instance, and the whole mass of phenomena included broadly under the term spiritualism, are in about the some position with regard to organized scientific thought to-day as was astronomy before astrology’s collapse, as was the study of electricity in the eighteenth century, or that of hypnotism in the middle of the nineteenth. What is more, the average man demands that phenomena of this order shall be included in his scheme of things. Science cannot yet do this for him; and accordingly the dwelling-place that we are building must still be incomplete; it is for those who come after to build the upper stories.

This cannot be helped. What we build, we must build firmly; on what is yet to be built, science cannot pronounce, except to say that she knows that it will be congruous with what has gone before.

What general principles, then, do we assume? We assume that the universe is composed throughout of the same matter, whose essential unity, in spite of the diversity of its so-called elements, the recent researches of physicists are revealing to us; we assume that matter behaves in the same way wherever it is found, showing the same mode of sequence of change, of cause and effect. We assume, on fairly good although indirect evidence, that there has been an evolution of the forms assumed by matter; that, in this solar system of ours, for instance, matter was once all in electronic form, that it then attained to the atomic and the molecular; that later, colloidal organic matter of a special type made its appearance, and later still, living matter arose. That the forms of life, simple at first, attained progressively to greater complexity; that mind, negligible in the lower forms, became of greater and greater importance, until it reached its present level in man.[45]

Unity, uniformity, and development are the three great principles that emerge. We know of no instance where the properties of matter change, though many where a new state of matter develops. The full properties of a molecular compound such as water, for instance, cannot be deduced at present from what we know about the properties of its constituent atoms of hydrogen and oxygen. The properties of the human mind cannot be deduced from our present knowledge of the minds of animals. New combinations and properties thus arise in time. Bergson miscalls such evolution “creative.” We had better, with Lloyd Morgan, call it “emergent.”

With mind, we find a gradual evolution from a state in which it is impossible to distinguish mental response from physiological reaction, up to the intensity and complexity of our own emotions and intellect. Since all material developments in evolution can be traced back step by step and shown to be specializations of one or more of the primitive properties of living matter, it is not only an economy of hypothesis, but also, in the absence of any evidence to the contrary, the proper conclusion, that mental properties also are to be traced back to the simplest and most original forms of life. What exact significance is to be attached to the term “mental properties” in such organisms, it is hard to say; we mean, however, that something of the same general nature as mind in ourselves is inherent in all life, something standing in the same relation to living matter in general as do our minds to the particular living matter of our brains.

But there can be no reasonable doubt that living matter, in due process of time, originated from non-living; and if that be so, we must push our conclusion farther, and believe that not only living matter, but all matter, is associated with something of the same general description as mind in higher animals. We come, that is, to a monistic conclusion, in that we believe that there is only one fundamental substance, and that this possesses not only material properties, but also properties for which the word _mental_ is the nearest approach. We want a new word to denote this _X_, this world-stuff; _matter_ will not do, for that is a word which the physicists and chemists have moulded to suit themselves, and since they have not yet learned to detect or measure mental phenomena, they restrict the word “material” to mean “non-mental,” and “matter” to mean that which has such “material” properties.

You will remember William of Occam’s razor; “Entia non multiplicanda praeter necessitatem”; when we are monists in the sense I have just outlined, we are using that weapon to shave away a very unrestrained growth of hair which has long obscured the features of reality.

Holding to these principles, we must, until evidence to the contrary is produced, reject any explanation which proceeds by cataclysms, or by miracles; a miracle becomes (when not an illusion) simply an event which is on the one hand uncommon, and for which, on the other, there has been found no explanation. Revelation too goes by the board--save a revelation which is simply a name for the progressive increase of knowledge and insight.

Last, but not least, we do not pretend to know the Absolute. We know phenomena, and our systems, in so far as scientific, are interpretations of phenomena.

Religion has been defined in a hundred different ways. It has been defined intellectually--as a creed; as myth; as a view of the universe; it has been defined emotionally as consisting in awe; in fear; in love; in mystical exaltation or communion. It has been defined from the standpoint of action--as worship; as ritual; as sacrifice; as morality. Matthew Arnold called it “morality tinged with emotion”; Salomon Reinach “a sum of scruples impeding the free use of human faculties.” Jevons makes the experiencing of God the central feature; and so on and so forth. Is it possible to find any common measure for all these statements? Would it not be better to unite with those who cut the Gordian knot by writing down all religion simply as illusion? No. For their point of view is meaningless. Even illusions are, in themselves, facts to be investigated; and even illusions have a basis.

But it is not necessary to believe that it is an illusion; the knot may be untied. Ritual, Creed, Morality, Mystical Experience--all these are manifestations of religion, but not religion itself. Religion itself is the reaction between man as a personality on the one side, and, on the other, all of the universe with which he comes in contact. It is not only ritual, for you may have obviously non-religious ritual, as in a court ceremonial or a legal function: it is not merely morality, for men may practise morality, the most austere or the most _terre à terre_, uninspired by anything that could remotely be called religious: it is not belief, for we may have beliefs of all kinds, even to the most complex scientific beliefs concerning the universe, which have yet no connection with religion: it is neither communion in itself, nor ecstasy in itself, as many lovers and poets could tell you.

But because it is a reaction of the whole personality, it must involve intellectual _and_ practical _and_ emotional processes: and because man has the powers of abstraction and association, or rather because his mind in most cases cannot help making associations and abstractions, it follows that it will inevitably concern itself, consciously or subconsciously, with all the phenomena that it encounters, will try to bring them all into its scheme, and will try to unify them and frame concepts to deal with them as a whole.

Some men will be more concerned on the emotional, others on the intellectual, others again on the moral side: but it is impossible to separate any one of the three aspects entirely from the others.

We will begin with and treat mainly of the intellectual aspect of the problem, the credal side. For one thing, science has more direct concern with it than with the others; for another, more continuous and startling alterations have had to be made in it; and finally, the actual problem is there felt most acutely at the present moment.

What, then, is the problem? In the terms of our definition of religion, it is in its most general terms as follows: Man has to live his life in a world in which he is confronted with forces and powers other than his own. He is a mere animalcule in comparison with the totality of these forces, his life a second in comparison with their centuries. By his mental constitution, he of necessity attempts to formulate some intelligible account of the constitution of the world and its relation to himself--or should we rather say in so far as it is in relation to himself?--and so we have a myth, a doctrine, or a creed.

At the present moment, as we have already seen, there appears to be an irreconcilable conflict between orthodox Christianity and orthodox Natural Science. The one asserts the existence of an omnipotent, omniscient, personal God--creator, ruler, and refuge. The other, by reducing ever more and more of natural phenomena to what we please to call natural laws--in other words, to orderly processes proceeding inevitably from the known constitution and properties of matter--has robbed such a God of ever more and more of his realm and possible power; until finally, with the rise of evolutionary biology and psychology, there seems to be no place any more for a God in the universe.

Stated thus, the opposition is complete. But let us return on our footsteps, and trace for one thing some of the history of religious beliefs, for another re-investigate, from a slightly unusual standpoint, the actual knowledge of the Universe which science has given us.

Man has developed: in early stages, his physical and mental capacities developed; in later stages development has been mainly restricted to his traditions, ideas, and achievements. As part of his development, his religious ideas have altered too.

At the beginning, he appears to have no ideas of a God of Gods at all--merely of influences and powers, obviously (he would say) inherent in the forces of Nature, magically inherent in certain objects and actions--fetishes and incantations. He seems scarcely to have been conscious of himself as an individual, or of the full distinction between self and the external world.

Later, perhaps as the idea of his own personality grew, he began to ascribe a more personal existence to the forces with which he came into contact, and so to turn them more and more into beings that can properly be called Gods: polydaemonism arose and in its turn gave place to polytheism.

But while rigid custom was at first the only morality, and each external power and each human activity was regarded separately, later the rise of civilization led to a modification of custom, to a reference of action and belief to the standards of pure reason, and to an attempt at unification. Once this occurred, and equally so whether the attempt at unification had an intellectual or a moral basis, polytheism was doomed. Its downfall has been often described; the reasons for it are suggestively put by Jevons in his little book, “The Idea of God.” It passes through a stage where one among the gods is pre-eminent: but finally even that does not suffice, and in its place arises a monotheistic creed.

Monotheism may start as a purely local or tribal affair--my one God against yours. It may not only start, but long continue so. Readers of Mr. Bang’s collection of startling German war-sayings will remember the superbly national prayer of the Prussian pastor who addressed his God (I quote from memory) as “Du, der hoch über Cherubinen, Seraphinen, und Zeppelinen ewig trönst.” (J. P. Bang, _Hurrah and Hallelujah_. London, 1916.) But this idea, too, is self-contradictory, and merges into that of one God for all men. The primitive anthropomorphism which had invested the first vague and mysterious spirits with human parts and passions, human speech and thought, also fell into gradual desuetude. It was kept up as a symbol, or because of the difficulty of describing a God except in terms human individuality, but its literal truth was deliberately denied. God became different from and more than man--omnipotent, omniscient, with no parts, with no limitations: but he retained personality--in other words, a mental or spiritual organization of the same general kind as man’s, however superior in degree. With time, the divine personality became compounded more and more of man’s ideals instead of his everyday thoughts and attributes. And thus and that God remains. He has created everything; he is in some sense immanent in the world, in some sense apart from it as its ruler--you take your choice according to your philosophic preferences. Beyond that, organized religious thought has not gone; and now it finds itself fronting science in an impasse.

That, very briefly and roughly, is how man’s idea of God has developed. But how have man’s knowledge and ideas of the natural universe developed? What has Science to say to the impasse?

Man has to deal with three great categories of phenomena--the inorganic, the organic, and the psychic. In the inorganic, chemistry first and then physics have given us a picture whose broad outlines are now familiar. There is but one type and store of energy in Nature, whether it drives a train, animates a man, radiates in heat or light, inheres in a falling stone. There is but one substance. All bodies of trees, of men, rivers and rocks, the clouds in the air and the air itself, precious stones and common clay--all can be resolved into a limited number of elements. And these elements in their turn can be resolved into combinations, differing, it appears, only quantitatively from each other, of electrical charges; so that at the last all matter is one, and becomes perhaps indistinguishable, or at least inseparable, from energy. There is no personal operator for particular happenings; the lightning and the volcano are the inevitable outcome of the material constitution of things, equally with the form and colour of a pebble and with the fact that it will drop to the ground if it is let fall. All is impersonal order and unity.

There is, however, one other great fact about the system of inorganic matter. The energy contained in it tends to be degraded, as the physicists say--in other words to become less readily available. There is available energy in moving matter. There is potential energy in all matter, dependent upon whether it can be set in motion. But if the sea were to cover the whole surface of the globe, it would be impossible to extract energy from running water as we do now, because no water would be running. So too heat is energy; but it is only available when it can flow, when there are hotter and colder bodies. The law under which transformations of energy operate has now been investigated, and it has been established that in every energy-transaction a certain modicum goes to waste as unavailable heat, so that, unless some at present unforeseen change occurs, the last state of the universe, considered as a purely physico-chemical mechanism, will be one of death, of inactivity, with all matter at a uniform low temperature and the whole stock of energy locked up and unavailable in this sea of tranquillity. True for one thing that an almost inconceivable number of millions of years must elapse before this “death of matter” is realized; and for another that we are unable to understand how such a progressive degradation could have been in operation from all eternity. We must not expect complete knowledge within a few years or a few centuries; but even if the beginning is veiled--for there is no more evidence for a “creation” than for (say) a rhythmic reversal of the direction of energy-availability--and if it is always possible that some unforeseen change in the process should occur before the whole runs down, yet it is a fact (and we are resolved to be agnostic save about facts) that, here and now, a direction is to be observed in the evolution of inorganic matter, by which natural operations are tending to become less active, and the amount of available energy is diminishing. If it continues indefinitely, first life, and later on all activity and change whatsoever will cease. There is a tendency towards death and towards unchanging inactivity.

The next great category is that of the organic, of living matter. We have to consider its origin and later history. So far as constitution goes, living matter is merely a special and highly complicated form of ordinary matter; and there can be no reasonable doubt that it has originated naturally from non-living matter.
