These guys go a long way (inadvertantly) doing their best to disprove this by demonstrating the prescience of the Prophet Chesterton:
In considering the elements of pagan humanity, we must begin by an attempt to describe the indescribable. Many get over the difficulty of describing it by the expedient of denying it, or at least ignoring it; but the whole point of it is that it was something that was never quite eliminated even when it was ignored. They are obsessed by their evolutionary monomania that every great thing grows from a seed, or something smaller than itself. They seem to forget that every seed comes from a tree, or something larger than itself. Now there is very good ground for guessing that religion did not originally come from some detail that was forgotten, because it was too small to be traced. Much more probably it was an idea that was abandoned because it was too large to be managed. There is very good reason to suppose that many people did begin with the simple but overwhelming idea of one God who governs all; and afterwards fell away into such things as demon-worship almost as a sort of secret dissipation. Even the test of savage beliefs, of which the folk-lore students are so fond, is admittedly often found to support such a view. Some of the very rudest savages, primitive in every sense in which anthropologists use the word, the Australian aborigines for instance, are found to have a pure monotheism with a high moral tone. A missionary was preaching to a very wild tribe of polytheists, who had told him all their polytheistic tales, and telling them in return of the existence of the one good God who is a spirit and judges men by spiritual standards. And there was a sudden buzz of excitement among these stolid barbarians, as at somebody who was letting out a secret, and they cried to each other, ‘Atahocan! He is speaking of Atahocan!’ Probably it was a point of politeness and even decency among those polytheists not to speak of Atahocan. The name is not perhaps so much adapted as some of our own to direct and solemn religious exhortation but many other social forces are always covering up and confusing such simple ideas. Possibly the old god stood for an old morality found irksome in more expansive moments; possibly intercourse with demons was more fashionable among the best people, as in the modern fashion of Spiritualism. Anyhow, there are any number of similar examples. They all testify to the unmistakable psychology of a thing taken for granted, as distinct from a thing talked about. There is a striking example in a tale taken down word for word from a Red Indian in California which starts out with hearty legendary and literary relish: ‘The sun is the father and ruler of the heavens. He is the big chief. The moon is his wife and the stars are their children’; and so on through a most ingenious and complicated story, in the middle of which is a sudden parenthesis saying that the sun and moon have to do something because ‘It is ordered that way by the Great Spirit Who lives above the place of all.’ That is exactly the attitude of most paganism towards God. He is something assumed and forgotten and remembered by accident; a habit possibly not peculiar to pagans. Sometimes the higher deity is remembered in the higher moral grades and is a sort of mystery. But always, it has been truly said, the savage is talkative about his mythology and taciturn about his religion. The Australian savages, indeed, exhibit a topsyturveydom such as the ancients might have thought truly worthy of the antipodes. The savage who thinks nothing of tossing off such a trifle as a tale of the sun and moon being the halves of a baby chopped in two, or dropping into small-talk about a colossal cosmic cow milked to make the rain, merely in order to be sociable, will then retire to secret caverns sealed against women and white men, temples of terrible initiation where to the thunder of the bull-roarer and the dripping of sacrificial blood, the priest whispers the final secrets, known only to the initiate: that honesty is the best policy, that a little kindness does nobody any harm, that all men are brothers and that there is but one God, the Father Almighty, maker of all things visible and invisible. In other words, we have here the curiosity of religious history that the savage seems to be parading all the most repulsive and impossible parts of his belief and concealing all the most sensible and creditable parts. But the explanation is that they are not in that sense parts of his belief, or at least not parts of the same sort of belief. The myths are merely tall stories, though as tall as the sky, the water spout, or the tropic rain. The mysteries are true stories, and are taken secretly that they may be taken seriously. Indeed it is only too easy to forget that there is a thrill in theism. A novel in which a number of separate characters all turned out to be the same character would certainly be a sensational novel. It is so with the idea that sun and tree and river are the disguises of one god and not of many. Alas, we also find it only too easy to take Atahocan for granted. But whether he is allowed to fade into a truism or preserved as a sensation by being preserved as a secret, it is clear that he is always either an old truism or an old tradition. There is nothing to show that he is an improved product of the mere mythology and everything to show that he preceded it. He is worshipped by the simplest tribes with no trace of ghosts or grave-offerings, or any of the complications in which Herbert Spencer and Grant Allen sought the origin of the simplest of all ideas. Whatever else there was, there was never as such thing as the Evolution of the Idea of God. The idea was concealed, was avoided, was almost forgotten, was even explained away; but it was never evolved.
There are not a few indications of this change in other places It is implied, for instance, in the fact that even polytheism seems often the combination of several monotheisms. A god will gain only a minor seat on Mount Olympus, when he had owned earth and heaven and all the stars while he lived in his own little valley. Like many a small nation melting in a great empire, he gives up local universality only to come under universal limitation. The very name of Pan suggests that he became a god of the wood when he had been a god of the world. The very name of Jupiter is almost a pagan translation of the words ‘Our Father which art in heaven.’ As with the Great Father symbolised by the sky, so with the Great Mother whom we still call Mother Earth. Demeter and Ceres and Cybele often seem to be almost capable of taking over the whole business of godhood, so that men should need no other gods. It seems reasonably probable that a good many men did have no other gods but one of these, worshipped as the author of all.
In short, there is a feeling that there is something higher than the gods; but because it is higher it is also further away. Not yet could even Virgil have read the riddle and the paradox of that other divinity, who is both higher and nearer. For them what was truly divine was very distant, so distant that they dismissed it more and more from their minds. It had less and less to do with the mere mythology of which I shall write later. Yet even in this there was a sort of tacit admission of its intangible purity, when we consider what most of the mythologies like. As the Jews would not degrade it by images, so the Greeks did not degrade it even by imaginations. When the gods were more and more remembered only by pranks and profligacies, it was relatively a movement of reverence. It was an act of piety to forget God. In other words, there is something in the whole tone of the time suggesting that men had accepted a lower level, and still were half conscious that it was a lower level. It is hard to find words for these things; yet the one really just word stands ready. These men were conscious of the Fall if they were conscious of nothing else; and the same is true of an heathen humanity. Those who have fallen may remember the fall, even when they forget the height. Some such tantalising blank or break in memory is at the back of all pagan sentiment. There is such a thing as the momentary power to remember that we forget. And the most ignorant of humanity know by the very look of earth that they have forgotten heaven. But it remains true that even for these men there were moments, like the memories of childhood, when they heard themselves talking with a simpler language; there were moments when the Roman, like Virgil in the line already quoted, cut his way with a sword-stroke of song out of the tangle of the mythologies, the motley mob of gods and goddesses sank suddenly out of sight and the Sky- Father was alone in the sky.
This latter example is very relevant to the next step in the process. A white light as of a lost morning still lingers on the figure of Jupiter, of Pan or of the elder Apollo; and it may well be, as already noted, that each was once a divinity as solitary as Jehovah or Allah. They lost this lonely universality by a process it is here very necessary to note; a process of amalgamation very like what was afterwards called syncretism. The whole pagan world set itself to build a Pantheon. They admitted more and more gods, gods not only of the Greeks but of the barbarians; gods not only of Europe but of Asia and Africa. The more the merrier, though some of the Asian and African ones were not very merry. They admitted them to equal thrones with their own, sometimes they identified them with their own. They may have regarded it as an enrichment of their religious life; but it meant the final loss of all that we now call religion. It meant that ancient light of simplicity, that had a single source like the sun, finally fades away in a dazzle of conflicting Lights and colours. God is really sacrificed to the Gods; in a very literal sense of the flippant phrase, they have been too many for him.
Polytheism, therefore, was really a sort of pool; in the sense of the pagans having consented to the pooling of their pagan religions. And this point is very important in many controversies ancient and modern. It is regarded as a liberal and enlightened thing to say that the god of the stranger may be as good as our own; and doubtless the pagans thought themselves very liberal and enlightened when they agreed to add to the gods of the city or the hearth some wild and fantastic Dionysus coming down from the mountains or some shaggy and rustic Pan creeping out of the woods. But exactly what it lost by these larger ideas is the largest idea of all. It is the idea of the fatherhood that makes the whole world one. And the converse is also true. Doubtless those more antiquated men of antiquity who clung to their solitary statues and their single sacred names were regarded as superstitious savages benighted and left behind. But these superstitious savages were preserving something that is much more like the cosmic power as conceived by philosophy, or even as conceived by science. This paradox by which the rude reactionary was a sort of prophetic progressive has one consequence very much to the point. In a purely historical sense, and apart from any other controversies in the same connection, it throws a light, a single and a steady light, that shines from the beginning on a little and lonely people. In this paradox, as in some riddle of religion of which the answer was sealed up for centuries, lies the mission and the meaning of the Jews.
Question Authority. Subvert the Dominant Paradigm. Suppose, just for a moment, that monotheism came first and was eventually drowned in polytheism by people who thought like, oh, the cosmopolitan and multicultural compromisers who emit things like “Against Monotheism” and that the process happened everywhere but in one small people. Interesting idea.
