In an earlier chapter we have already indicated the essential conditions which lead to the origin of religious beliefs, and there is no need again to go over that ground. What is necessary at present is to sketch as briefly as is consistent with lucidity those frames of mind to which the belief in God owes its existence.

To realize this no very recondite instrument of research is required. We need nothing more elaborate than the method by which we are hourly in the habit of estimating each other's thoughts, and of gauging one another's motives. When I see a man laugh I assume that he is pleased; when he frowns I assume that he is angry. There is here only an application of the generally accepted maxim that when we see identical results we are warranted in assuming identical causes. In this way we can either argue from causes to effects or from effects to causes. A further statement of the same principle is that when we are dealing with biological facts we may assume that identical structures imply identical functions. The structure of a dead animal will tell us what its functions were when living as certainly as though we had the living animal in front of us. We may relate function to structure or structure to function. And in this we are using nothing more uncommon than the accepted principle of universal causation.

Now, in all thinking there are two factors. There is the animal or human brain, the organ of thought, and there is the material for thought as represented by the existing knowledge of the world. If we had an exact knowledge of the kind of brain that functioned, and the exact quantity and quality of the knowledge existing, the question as to the ideas which would result would be little more than a problem in mathematics. We could make the calculation with the same assurance that an astronomer can estimate the position of a planet a century hence. In the case of primitive mankind we do not possess anything like the exact knowledge one would wish, but we do know enough to say in rather more than a general way the kind of thinking of which our earliest ancestors were capable, and what were its products. We can get at the machinery of the primitive brain, and can estimate its actions, and that without going further than we do when we assume that primitive man was hungry and thirsty, was pleased and angry, loved and feared. And, indeed, it was because he experienced fear and pleasure and love and hate that the gods came into existence.

Of the factors which determine the kind of thinking one does, we know enough to say that there were two things certain of early mankind. We know the kind of thinking of which he was capable, and we have a general notion of the material existing for thinking. Speaking of one of these early ancestors of ours, Professor Arthur Keith says, "Piltdown man saw, heard, felt, thought and dreamt much as we do," that is, there was the same kind of brain at work that is at work now. And that much we could be sure of by going no farther back than the savages of to-day. But as size of brain is not everything, we are warranted in saying that the brain was of a relatively simple type, while the knowledge of the world which existed, and which gives us the material for thinking, was of a very imperfect and elementary character. There was great ignorance, and there was great fear. From these two conditions, ignorance and fear, sprang the gods. Of that there is no doubt whatever. There is scarcely a work which deals with the life of primitive peoples to-day that does not emphasize that fact. Consciously or unconsciously it cannot avoid doing so. Long ago a Latin writer hit on this truth in the well-known saying, "Fear made the gods," and Aristotle expressed the same thing in a more comprehensive form by saying that fear first set man philosophizing. The undeveloped mind troubles little about things so long as they are going smoothly and comfortably. It is when something painful happens that concern is awakened. And all the gods of primitive life bear this primal stamp of fear. That is why religion, with its persistent harking back to the primitive, with its response to the "Call of the Wild" still dwells upon the fear of the Lord as a means of arousing a due sense of piety. The gods fatten on fear as a usurer does upon the folly of his clients, and in both cases the interest demanded far outweighs the value of the services rendered. At a later stage man faces his gods in a different spirit; he loses his fear and examines them; and gods that are not feared are but poor things. They exist mainly as indisputable records of their own deterioration.

Now to primitive man, struggling along in a world of which he was so completely ignorant, the one certain thing was that the world was alive. The wind that roared, the thunder that growled, the disease that left him so mysteriously stricken, were all so many living things. The division of these living forces into good and bad followed naturally from this first conception of their nature. And whatever be the stages of that process the main lines admit of no question, nor is there any question as to the nature of the conditions that brought the gods into existence. On any scientific theory of religion the gods represent no more than the personified ignorance and fear of primitive humanity. However much anthropologists may differ as to whether the god always originates from the ghost or not, whether animism is first and the worship of the ghost secondary or not, there is agreement on that point. Whichever theory we care to embrace, the broad fact is generally admitted that the gods are the products of ignorance and fear. Man fears the gods as children and even animals fear the unknown and the dangerous.

And as the gods are born of conditions such as those outlined, as man reads his own feelings and passions and desires into nature, so we find that the early gods are frankly, obtrusively, man-like. The gods are copies of their worshippers, faithful reflections of those who fear them. This, indeed, remains true to the end. When the stage is reached that the idea of God as a physical counterpart of man becomes repulsive, it is still unable to shake off this anthropomorphic element. To the modern worshipper God must not possess a body, but he must have love, and intelligence—as though the mental qualities of man are less human than the bodily ones! They are as human as arms or legs. And every reason that will justify the rejection of the conception of the universe being ruled over by a being who is like man in his physical aspects is equally conclusive against believing the universe to be ruled over by a being who resembles man in his mental characteristics. The one belief is a survival of the other; and the one would not now be accepted had not the other been believed in beforehand.

I have deliberately refrained from discussing the various arguments put forward to justify the belief in God in order that attention should not be diverted from the main point, which is that the belief in deity owes its existence to the ignorant interpretation of natural happenings by early or uncivilized mankind. Everything here turns logically on the question of origin. If the belief in God began in the way I have outlined, the question of veracity may be dismissed. The question is one of origin only. It is not a question of man first seeing a thing but dimly and then getting a clearer vision as his knowledge becomes more thorough. It is a question of a radical misunderstanding of certain experiences, the vogue of an altogether wrong interpretation, and its displacement by an interpretation of a quite different nature. The god of the savage was in the nature of an inference drawn from the world of the savage. There was the admitted premiss and there was the obvious conclusion. But with us the premiss no longer exists. We deliberately reject it as being altogether unwarrantable. And we cannot reject the premiss while retaining the conclusion. Logically, the god of the savage goes with the world of the savage; it should have no place in the mind of the really civilized human being.

It is for this reason that I am leaving on one side all those semi-metaphysical and pseudo-philosophical arguments that are put forward to justify the belief in God. As I have already said, they are merely excuses for continuing a belief that has no real warranty in fact. No living man or woman believes in God because of any such argument. We have the belief in God with us to-day for the same reason that we have in our bodies a number of rudimentary structures. As the one is reminiscent of an earlier stage of existence so is the other. To use the expressive phrase of Winwood Reade's, we have tailed minds as well as tailed bodies. The belief in God meets each newcomer to the social sphere. It is forced upon them before they are old enough to offer effective resistance in the shape of acquired knowledge that would render its lodgement in the mind impossible. Afterwards, the dice of social power and prestige are loaded in its favour, while the mental inertia of some, and the self-interest of others, give force to the arguments which I have called mere mental subterfuges for perpetuating the belief in God.

Only one other remark need be made. In the beginning the gods exist as the apotheosis of ignorance. The reason the savage had for believing in God was that he did not know the real causes of the phenomena around him. And that remains the reason why people believe in deity to-day. Under whatever guise the belief is presented, analysis brings it ultimately to that. The whole history of the human mind, in relation to the idea of God, shows that so soon as man discovers the natural causes of any phenomenon or group of phenomena the idea of God dies out in connection therewith. God is only conceived as a cause or as an explanation so long as no other cause or explanation is forthcoming. In common speech and in ordinary thought we only bring in the name of God where uncertainty exists, never where knowledge is obtainable. We pray to God to cure a fever, but never to put on again a severed limb. We associate God with the production of a good harvest, but not with a better coal output. We use "God only knows" as the equivalent of our own ignorance, and call on God for help only where our own helplessness is manifest. The idea remains true to itself throughout. Born in ignorance and cradled in fear, it makes its appeal to the same elements to the end. And if it apes the language of philosophy, it does so only as do those who purchase a ready-made pedigree in order to hide the obscurity of their origin.
