Chapter 10

The moon being inhabited then by human beings, but being very insufficiently supplied with air, it necessarily follows that these human beings must be provided in some way with the means of existing in that rare and tenuous atmosphere. Tremendous powers of inspiration and expiration would be required to make that air support the life of the human body. Although Swedenborg could have had no knowledge of the exact way in which breathing supports life (for Priestley was his junior by nearly half a century), yet he must clearly have perceived that the quantity of air inspired has much to do with the vitalising power of the indraught. No ordinary human lungs could draw in an adequate supply of air from such an atmosphere as the moon's; but by some great increase of breathing power it might be possible to live there: at least, in Swedenborg's time there was no reason for supposing otherwise. Reason, then, having convinced him that the lunar inhabitants must possess extraordinary breathing apparatus, and presumably most powerful voices, imagination presented them to him accordingly. 'Some spirits appeared overhead,' he says, 'and thence were heard voices like thunder; for their voices sounded precisely like thunder from the clouds after lightning. I supposed it was a great multitude of spirits who had the art of giving voices with such a sound. The more simple spirits who were with me derided them, which greatly surprised me. But the cause of their derision was soon discovered, which was, that the spirits who thundered were not many, but few, and were as little as children, and that on former occasions they (the thunderers) had terrified them by such sounds, and yet were unable to do them the least harm. That I might know their character, some of them descended from on high, where they thundered; and, what surprised me, one carried another on his back, and the two thus approached me. Their faces appeared not unhandsome, but longer than those of other spirits. In stature they were like children of seven years old, but the frame was more robust, so that they were like men. It was told me by the angels that they were from the moon. He who was carried by the other came to me, applying himself to my left side under the elbow, and thence spoke. He said, that when they utter their voices they thunder in this way,'--and it seems likely enough that if there are any living speaking beings in the moon, their voice, could they visit the earth, would be found to differ very markedly from the ordinary human voice. 'In the spiritual world their thunderous voices have their use. For by their thundering the spirits from the moon terrify spirits who are inclined to injure them, so that the lunar spirits go in safety where they will. To convince me the sound they make was of this kind, he (the spirit who was carried by the other) retired, but not out of sight, and thundered in like manner. They showed, moreover, that the voice was thundered by being uttered from the abdomen like an eructation. It was perceived that this arose from the circumstance that the inhabitants of the moon do not, like the inhabitants of other earths, speak from the lungs, but from the abdomen, and thus from air collected there, the reason of which is that the atmosphere with which the moon is surrounded is not like that of other earths.'

In his intercourse with spirits from Jupiter, Swedenborg heard of animals larger than those that live on the earth. It has been a favourite idea of many believers in other worlds than ours, that though in each world the same races of animals exist, they would be differently proportioned; and there has been much speculation as to the probable size of men and other animals in worlds much larger or much smaller than the earth. When as yet ideas about other worlds were crude, the idea prevailed that giants exist in the larger orbs, and pygmies in the smaller. Whether this idea had its origin in conceptions as to the eternal fitness of things or not, does not clearly appear. It seems certainly at first view natural enough to suppose that the larger beings would want more room and so inhabit the larger dwelling-places. It was a pleasing thought that, if we could visit Jupiter or Saturn, we should find the human inhabitants there

In bigness to surpass earth's giant sons;

but that if we could visit our moon or Mercury, or whatever smaller worlds there are, we should find men

Now less than smallest dwarfs, in narrow room Throng numberless, like that pygmaean race Beyond the Indian mount; or fairy elves, Whose midnight revels, by a forest side Or fountain, some belated peasant sees, Or dreams he sees.

Later the theory was started that the size of beings in various worlds depends on the amount of light received from the central sun. Thus Wolfius asserted that the inhabitants of Jupiter are nearly fourteen feet high, which he proved by comparing the quantity of sunlight which reaches the Jovians with that which we Terrenes receive. Recently, however, it has been noted that the larger the planet, the smaller in all probability must be the inhabitants, if any. For if there are two planets of the same density but unequal size, gravity must be greater at the surface of the larger planet, and where gravity is great large animals are cumbered by their weight. It is easy to see this by comparing the muscular strength of two men similarly proportioned, but unequal in height. Suppose one man five feet in height, the other six; then the cross section of any given muscle will be less for the former than for the latter in the proportion of twenty-five (five times five) to thirty-six (six times six). Roughly, the muscular strength of the bigger man will be half as great again as that of the smaller. But the weights of the men will be proportioned as 125 (five times five times five) to 216 (six times six times six), so that the weight of the bigger man exceeds that of the smaller nearly as seven exceeds four, or by three-fourths. The taller man exceeds the smaller, then, much more in weight than he does in strength; he is accordingly less active in proportion to his size. Within certain limits, of course, size increases a man's effective as well as his real strength. For instance, our tall man in the preceding illustration cannot lift his own weight as readily as the small man can lift his; but he can lift a weight of three hundred pounds as easily as the small man can lift a weight of two hundred pounds. When we get beyond certain limits of height, however, we get absolute weakness as the result of the increase of weight. Swift's Brobdingnags, for instance, would have been unable to stand upright; for they were six times as tall as men, and therefore each Brobdingnag would have weighed 216 times as much as a man, but would have possessed only thirty-six times the muscular power. Their weight would have been greater, then, in a sixfold greater degree than their strength, and, so far as their mere weight was concerned, their condition would have resembled that of an ordinary man under a load five times exceeding his own weight. As no man could walk or stand upright under such a load, so the Brobdingnags would have been powerless to move, despite, or rather because of, their enormous stature. Applying the general considerations here enunciated to the question of the probable size of creatures like ourselves in other planets, we see that men in Jupiter should be much smaller, men in Mercury much larger, than men on the earth. So also with other animals.

But Swedenborg's spirit visitors from these planets taught differently. 'The horses of our earth,' he says, 'when seen by the spirits of Jupiter, appeared to me smaller than usual, though rather robust; which arose from the idea those spirits had respecting them. They informed me that among them there are animals similar, though much larger; but that they are wild, and in the woods, and that when they come in sight they cause terror though they are harmless; they added that their terror of them is natural or innate.'[28] On the other hand the inhabitants of Mercury, who might be thirteen feet high yet as active as our men, appeared slenderer than Terrene men. 'I was desirous to know,' says Swedenborg, 'what kind of face and person the people in Mercury have, compared with those of the people on our earth. There therefore stood before me a female exactly resembling the women on that earth. Her face was beautiful, but it was smaller than that of a woman of our earth; she was more slender, but of equal height; she wore a linen head-dress, not artfully yet gracefully disposed. A man also was presented. He, too, was more slender than the men of our earth; he wore a garment of deep blue, closely fitted to his body without folds or flowing skirts. Such, I learn, were the personal form and costume of the humans of that earth. Afterwards there was shown me a species of the oxen and cows, which did not indeed differ much from those on our earth, except that they were smaller, and made some approach to the stag and hind species.' We have seen, too, that the lunar spirits were no larger than children seven years old.

One passage of Swedenborg's description of Jupiter is curious. 'Although on that earth,' he says, 'spirits speak with men' (_i.e._ with Jovian men) 'man in his turn does not speak with spirits, except to say, when instructed, _that he will do so no more_,'--which we should regard as a bull if it were not news from the Jovian spirit world. 'Nor is man allowed to tell anyone that a spirit has spoken to him; if he does so, he is punished. Those spirits of Jupiter when they were with me, at first supposed they were with a man of their own earth; but when in my turn I spoke with them, and thought of publishing what passed between us and so relating it to others, then, because they were not allowed to chastise me, they discovered they were with a stranger.'

It has been a favourite idea with those who delight in the argument from design, that the moons of the remoter planets have been provided for the express purpose of making up for the small amount of sunlight which reaches those planets. Jupiter receives only about one twenty-seventh part of the light which we receive from the sun; but then, has he not four moons to make his nights glorious? Saturn is yet farther away from the sun, and receives only the ninetieth part of the light we get from the sun; but then he has eight moons and his rings, and the nocturnal glory of his skies must go far to compensate the Saturnians for the small quantity of sunlight they receive. The Saturnian spirits who visited Swedenborg were manifestly indoctrinated with these ideas. For they informed him that the nocturnal light of Saturn is so great that some Saturnians worship it, calling it the Lord. These wicked spirits are separated from the rest, and are not tolerated by them. 'The nocturnal light,' say the spirits, 'comes from the immense ring which at a distance encircles that earth, and from the moons which are called the satellites of Saturn.' And again, being questioned further 'concerning the great ring which appears from our earth to rise above the horizon of that planet, and to vary its situations, they said that it does not appear to them as a ring, but only as a snow-white substance in heaven in various directions.' Unfortunately for our faith in the veracity of these spirits, it is certain that the moons of Saturn cannot give nearly so much light as ours, while the rings are much more effective as darkeners than as illuminators. One can readily calculate the apparent size of each of the moons as seen from Saturn, and thence show that the eight discs of the moons together are larger than our moon's disc in about the proportion of forty-five to eight. So that if they were all shining as brightly as our full moon and all full at the same time, their combined light would exceed hers in that degree. But they are not illuminated as our moon is. They are illuminated by the same remote sun which illuminates Saturn, while our moon is illuminated by a sun giving her as much light as we ourselves receive. Our moon then is illuminated ninety times more brightly than the moons of Saturn, and as her disc is less than all theirs together, not as one to ninety, but as sixteen to ninety, it follows that all the Saturnian moons, if full at the same time, would reflect to Saturn one-sixteenth part of the light which we receive from the full moon.[29] As regards the rings of Saturn, nothing can be more certain than that they tend much more to deprive Saturn of light then to make up by reflection for the small amount of light which Saturn receives directly from the sun. The part of the ring which lies between the planet and the sun casts a black shadow upon Saturn, this shadow sometimes covering an extent of surface many times exceeding the entire surface of our earth. The shadow thus thrown upon the planet creeps slowly, first one way, then another, northwards and southwards over the illuminated hemisphere of the planet (as pictured in the 13th plate of my treatise on Saturn), requiring for its passage from the arctic to the antarctic regions and back again to the arctic regions of the planet, a period nearly equal to that of a generation of terrestrial men. Nearly thirty of our years the process lasts, during half of which time the northern hemisphere suffers, and during the other half the southern. The shadow band, which be it remembered stretches right athwart the planet from the extreme eastern to the extreme western side of the illuminated hemisphere, is so broad during the greater part of the time that in some regions (those corresponding to our temperate zones) the shadow takes two years in passing, during which time the sun cannot be seen at all, unless for a few moments through some chinks in the rings, which are known to be not solid bodies, but made up of closely crowded small moons. And the slow passage of this fearful shadow, which advances at the average rate of some twenty miles a day, but yet hangs for years over the regions athwart which it sweeps, occurs in the very season when the sun's small direct supply of heat would require to be most freely compensated by nocturnal light--in the winter season, namely, of the planet. Moreover, not only during the time of the shadow's passage, but during the entire winter half of the Saturnian year, the ring reflects no light during the night time, the sun being on the other or summer side of the ring's plane.[30] The only nocturnal effect which would be observable would be the obliteration of the stars covered by the ring system. It is strange that, this being so, the spirits from Saturn should have made no mention of the circumstance; and even more strange that these spirits and others should have asserted that the moons and rings of Saturn compensate for the small amount of light directly received from the sun. Most certainly a Swedenborg of our own time would find the spirits from Saturn more veracious and more communicative about these matters, though even what _he_ would hear from the spirits would doubtless appear to sceptics of the twenty-first century to be no more than he could have inferred from the known facts of the science of his day.

But Swedenborg was not content merely to receive visits from the inhabitants of other planets in the solar system. He was visited also by the spirits of earths in the starry heaven; nay, he was enabled to visit those earths himself. For man, even while living in the world, 'is a spirit as to his interiors, the body which he carries about in the world only serving him for performing functions in this natural or terrestrial sphere, which is the lowest.' And to certain men it is granted not only to converse as a spirit with angels and spirits, but to traverse in a spiritual way the vast distances which separate world from world and system from system, all the while remaining in the body. Swedenborg was one of these. 'The interiors of my spirit,' he says, 'are opened by the Lord, so that while I am in the body I can at the same time be with angels in heaven, and not only converse with them, but behold the wonderful things which are there and describe them, that henceforth it may no more be said, "Who ever came from heaven to assure us it exists and tell us what is there?" He who is unacquainted with the arcana of heaven cannot believe that man can see earths so remote, and give any account of them from sensible experience. But let him know that spaces and distances, and consequently progressions, existing in the natural world, in their origin and first causes are changes of the state of the interiors; that with angels and spirits progressions appear according to changes of state; and that by changes of state they may be apparently translated from one place to another, and from one earth to another, even to earths at the boundaries of the universe; so likewise may man as to his spirit, his body still remaining in its place. This has been the case with me.'

Before describing his visits to earths in the starry heavens, Swedenborg is careful to indicate the probability that such earths exist. 'It is well known to the learned world,' he says, 'that every star is a sun in its place, remaining fixed like the sun of our earth.' The proper motions of the stars had, alas! not been discovered in Swedenborg's day, nor does he seem to have been aware what a wild chase he was really entering upon in his spiritual progressions. Conceive the pursuit of Sirius or Vega as either sun rushed through space with a velocity of thirty or forty miles in every second of time! To resume, however, the account which Swedenborg gives of the ideas of the learned world of his day. 'It is the distance which makes a star appear in a small form; consequently' (the logical necessity is not manifest, however) 'each star, like the sun of our system, has around it planets which are earths; and the reason these are not visible to us is because of their immense distance and their having no light but from their own star, which light cannot be reflected so far as to reach us.' 'To what other end,' proceeds this most convincing reasoning, 'can be so immense a heaven with such a multitude of stars? For man is the end for which the universe was created. It has been ascertained by calculation that supposing there were in the universe a million earths, and on every earth three hundred millions of men and two hundred generations within six thousand years, and that to every man or spirit was allotted a space of three cubic ells, the collective number of men or spirits could not occupy a space equal to a thousandth part of this earth, thus not more than that occupied by one of the satellites of Jupiter or Saturn; a space on the universe almost undiscernible, for a satellite is hardly visible to the naked eye. What would this be for the Creator of the universe, to whom the whole universe filled with earths could not be enough' (for what?), 'seeing that he is infinite.' However, it is not on this reasoning alone that Swedenborg relies. He tells us, honestly beyond all doubt, that he knows the truth of what he relates. 'The information I am about to give,' he says, 'respecting the earths in the starry heaven is from experimental testimony; from which it will likewise appear how I was translated thither as to my spirit, the body remaining in its place.'

His progress in his first star-hunt was to the right, and continued for about two hours. He found the boundary of our solar system marked first by a white but thick cloud, next by a fiery smoke ascending from a great chasm. Here some guards appeared, who stopped some of the company, because these had not, like Swedenborg and the rest, received permission to pass. They not only stopped those unfortunates, but tortured them, conduct for which terrestrial analogues might possibly be discovered.

Having reached another system, he asked the spirits of one of the earths there how large their sun was and how it appeared. They said it was less than the sun of our earth, and has a flaming appearance. Our sun, in fact, is larger than other suns in space, for from that earth starry heavens are seen, and a star larger than the rest appears, which, say those spirits, 'was declared from heaven' to be the sun of Swedenborg's earthly home.

What Swedenborg saw upon that earth has no special interest. The men there, though haughty, are loved by their respective wives because they, the men, are good. But their goodness does not appear very manifest from anything in the narrative. The only man seen by Swedenborg took from his wife 'the garment which she wore, and threw it over his own shoulders; loosening the lower part, which flowed down to his feet like a robe (much as a man of our earth might be expected to loosen the tie-back of the period, if he borrowed it in like manner) he thus walked about clad.'

He next visited an earth circling round a star, which he learned was one of the smaller sort, not far from the equator. Its greater distance was plain from the circumstance that Swedenborg was two days in reaching it. In this earth he very nearly fell into a quarrel with the spirits. For hearing that they possess remarkable keenness of vision, he 'compared them with eagles which fly aloft, and enjoy a clear and extensive view of objects beneath.' At this they were indignant, supposing, poor spirits, 'that he compared them to eagles as to their rapacity, and consequently thought them wicked.' He hastened to explain, however, that he 'did not liken them to eagles as to their rapacity, but as to sharpsightedness.'

Swedenborg's account of a third earth in the star-depths contains a very pretty idea for temples and churches. The temples in that earth 'are constructed,' he says, of trees, not cut down, but growing in the place where they were first planted. On that earth, it seems, there are trees of an extraordinary size and height; these they set in rows when young, and arrange in such an order that they may serve when they grow up to form porticoes and colonnades. In the meanwhile, by cutting and pruning, they fit and prepare the tender shoots to entwine one with another, and join together so as to form the groundwork and floor of the temple to be constructed, and to rise at the sides as walls, and above to bend into arches to form the roof. In this manner they construct the temple with admirable art, elevating it high above the ground. They prepare also an ascent into it, by continuous branches of the trees, extended from the trunk and firmly connected together. Moreover, they adorn the temple without and within in various ways, by disposing the foliage into particular forms; thus they build entire groves. But it was not permitted me to see the nature of these temples, only I was informed that the light of their sun is let in by apertures amongst the branches, and is everywhere transmitted through crystals; whereby the light falling on the walls is refracted in colours like those of the rainbow, particularly blue and orange, of which they are fondest. Such is their architecture, which they prefer to the most magnificent palaces of our earth.'
