THE planet on which we now descended after our long flight among the stars was the first of many to be visited. In some we stayed, according to the local calendar, only a few weeks, in others several years, housed together in the mind of some native. Often when the time came for our departure our host would accompany us for subsequent adventures. As we passed from world to world, as experience was piled upon experience like geological strata, it seemed that this strange tour of worlds was lasting for many lifetimes. Yet thoughts of our own home-planets were constantly with us. Indeed, in my case it was not till I found myself thus exiled that I came to realize fully the little jewel of personal union that I had left behind. I had to comprehend each world as best I could by reference to the remote world where my own life had happened, and above all by the touchstone of that common life that she and I had made together.

Before trying to describe, or rather suggest, the immense diversity of worlds which I entered, I must say a few words about the movement of the adventure itself. After the experiences which I have just recorded it was clear that the method of disembodied flight was of little use. It did indeed afford us extremely vivid perception of the visible features of our galaxy; and we often used it to orientate ourselves when we had made some fresh discovery by the method of psychological attraction. But since it gave us freedom only of space and not of time, and since, moreover, planetary systems were so very rare, the method of sheer random physical flight alone was almost infinitely unlikely to produce results. Physical attraction, however, once we had mastered it, proved very effective. This method depended on the imaginative reach of our own minds. At first, when our imaginative power was strictly limited by experience of our own worlds, we could make contact only with worlds closely akin to our own. Moreover, in this novitiate stage of our work we invariably came upon these worlds when they were passing through the same spiritual crisis as that which underlies the plight of Homo sapiens today. It appeared that, for to enter any world at all, there had to be a deep-lying likeness or identity in ourselves and our hosts.

As we passed on from world to world we greatly increased our understanding of the principles underlying our venture, and our powers of applying them. Further, in each world that we visited we sought out a new collaborator, to give us insight into his world and to extend our imaginative reach for further exploration of the galaxy. This “snowball” method by which our company was increased was of great importance, since it magnified our powers. In the final stages of the exploration we made discoveries which might well be regarded as infinitely beyond the range of any single and unaided human mind.

At the outset Bvalltu and I assumed that we were embarking on a purely private adventure; and later, as we gathered helpers, we still believed that we ourselves were the sole initiators of cosmical exploration. But after a while we came in psychical contact with another group of cosmical explorers, natives of worlds as yet unknown to us. With these adventurers, after difficult and often distressing experiments, we joined forces, entering first into intimate community, and later into that strange mental union which Bvalitu and I had already experienced together in some degree on our first voyage among the stars.

When we had encountered many more such groups, we realized that, though each little expedition had made a lonely start, all were destined sooner or later to come together. For, no matter now alien from one another at the outset, each group gradually acquired such far-reaching imaginative power that sooner or later it was sure to make contact with others.

In time it became clear that we, individual inhabitants of a host of other worlds, were playing a small part in one of the great movements by which the cosmos was seeking to know itself, and even see beyond itself.

In saying this I do not for a moment claim that, because I have shared in this vast process of cosmical self-discovery, the story which I have to tell is true in a fully literal sense. Plainly it does not deserve to be taken as part of the absolute objective truth about the cosmos. I, the human individual, can only in a most superficial and falsifying way participate in the superhuman experience of that communal “I” which was supported by the innumerable explorers. This book must needs be a ludicrously false caricature of our actual adventure. But further, though we were and are a multitude drawn from a multitude of spheres, we represent only a tiny fraction of the diversity of the whole cosmos. Thus even the supreme moment of our experience, when it seemed to us that we had penetrated to the very heart of reality, must in fact have given us no more than a few shreds of truth, and these not literal but symbolic.

My account of that part of my adventure which brought me into contact with worlds of more or less human type may be fairly accurate; but that which deals with more alien spheres must be far from the truth. The Other Earth I have probably described with little more falsehood than our historians commit in telling of the past ages of Homo sapiens. But of the less human worlds, and the many fantastic kinds of beings which we encountered up and down the galaxy and throughout the whole cosmos, and even beyond it, I shall perforce make statements which, literally regarded, must be almost wholly false. I can only hope that they have the kind of truth that we sometimes find in myths.

Since we were now free of space, we ranged with equal ease over the nearer and the remoter tracts of this galaxy. That we did not till much later make contact with minds in other galaxies was not due to any limitations imposed by space, but seemingly to our own inveterate parochialism, to a strange limitation of our own interest, which for long rendered us inhospitable to the influence of worlds lying beyond the confines of the Milky Way. I shall say more of this curious restriction when I come to describe how we did at last outgrow it.

Along with freedom of space we had freedom of time. Some of the worlds that we explored in this early phase of our adventure ceased to exist long before my native planet was formed; others were its contemporaries; others were not born till the old age of our galaxy, when the Earth had been destroyed, and a large number of the stars had already been extinguished.

As we searched up and down time and space, discovering more and more of the rare grains called planets, as we watched race after race struggle to a certain degree of lucid consciousness, only to succumb to some external accident or, more often, to some flaw in its own nature, we were increasingly oppressed by a sense of the futility, the planlessness of the cosmos. A few worlds did indeed wake to such lucidity that they passed beyond our ken. But several of the most brilliant of these occurred in the earliest epoch of the galactic story; and nothing that we could as yet discover in the later phases of the cosmos suggested that any galaxies, still less the cosmos as a whole, had at last come (or will at last come) more under the sway of the awakened spirit than they were during the epoch of those early brilliant worlds. Not till a much later stage of our inquiry were we fitted to discover the glorious but ironical and heart-rending climax for which this vast proliferation of worlds was but a prologue.

In the first phase of our adventure, when, as I have said, our powers of telepathic exploration were incomplete, every world that we entered turned out to be in the throes of the same spiritual crisis as that which we knew so well on our native planets. This crisis I came to regard as having two aspects. It was at once a moment in the spirit’s struggle to become capable of true community on a world-wide scale; and it was a stage in the age-long task of achieving the right, the finally appropriate, the spiritual attitude toward the universe.

In every one of these “chrysalis” worlds thousands of millions of persons were flashing into existence, one after the other, to drift gropingly about for a few instants of cosmical time before they were extinguished. Most were capable, at least in some humble degree, of the intimate kind of community which is personal affection; but for nearly all of them a stranger was ever a thing to fear and hate. And even their intimate loving was inconstant and lacking in insight. Nearly always they were intent merely on seeking for themselves respite from fatigue or boredom, fear or hunger. Like my own race, they never fully awoke from the primeval sleep of the subman. Only a few here and there, now and then, were solaced, goaded, or tortured by moments of true wakefulness. Still fewer attained a clear and constant vision, even of some partial aspect of truth; and their half-truths they nearly always took to be absolute. Propagating their little partial truths, they bewildered and misdirected their fellow mortals as much as they helped them.

Each individual spirit, in nearly all these worlds, attained at some point in life some lowly climax of awareness and of spiritual integrity, only to sink slowly or catastrophically back into nothingness. Or so it seemed. As in my own world, so in all these others, lives were spent in pursuit of shadowy ends that remained ever just round the comer. There were vast tracts of boredom and frustration, with here and there some rare bright joy. These were ecstasies of personal triumph, of mutual intercourse and love, of intellectual insight, of aesthetic creation. There were also religious ecstasies; but these, like all else in these worlds, were obscured by false interpretations. There were crazy ecstasies of hate and cruelty, felt against individuals and against groups. Sometimes during this early phase of our adventure we were so distressed by the incredible bulk of suffering and of cruelty up and down the worlds that our courage failed, our telepathic powers were disordered, and we slipped toward madness.

Yet most of these worlds were really no worse than our own. Like us, they had reached that stage when the spirit, half awakened from brutishness and very far from maturity, can suffer most desperately and behave most cruelly. And like us, these tragic but vital worlds, visited in our early adventures, were agonized by the inability of their minds to keep pace with changing circumstance. They were always behindhand, always applying old concepts and old ideals inappropriately to novel situations. Like us, they were constantly tortured by their hunger for a degree of community which their condition demanded but their poor, cowardly, selfish spirits could by no means attain. Only in couples and in little circles of companions could they support true community, the communion of mutual insight and respect and love. But in their tribes and nations they conceived all too easily the sham community of the pack, baying in unison of fear and hate.

Particularly in one respect these races were recognizably our kin. Each had risen by a strange mixture of violence and gentleness. The apostles of violence and the apostles of gentleness swayed them this way and that. At the time of our visit many of these worlds were in the throes of a crisis of this conflict. In the recent past, loud lip-service had been paid to gentleness and tolerance and freedom; but the policy had failed, because there was no sincere purpose in it, no conviction of the spirit, no true experience of respect for individual personality. All kinds of self-seeking and vindic-tiveness had nourished, secretly at first, then openly as shameless individualism. Then at last, in rage, the peoples turned away from individualism and plunged into the cult of the herd. At the same time, in disgust with the failure of gentleness, they began openly to praise violence, and the ruthlessness of the god-sent hero and of the armed tribe. Those who thought they believed in gentleness built up armaments for their tribes against those foreign tribes whom they accused of believing in violence. The highly developed technique of violence threatened to destroy civilization; year by year gentleness lost ground. Pew could understand that their world must be saved, not by violence in the short run, but by gentleness in the long run. And still fewer could see that, to be effective, gentleness must be a religion; and that lasting peace can never come till the many have wakened to the lucidity of consciousness which, in all these worlds, only the few could as yet attain.

If I were to describe in detail every world that we explored, this book would develop into a world of libraries. I can give only a few pages to the many types of worlds encountered in this early stage of our adventure, up and down the whole breadth and length and the whole duration of our galaxy. Some of these types had apparently very few instances; other occurred in scores or hundreds.

The most numerous of all classes of intelligent worlds is that which includes the planet familiar to readers of this book. Homo sapiens has recently flattered and frightened himself by conceiving that, though perhaps he is not the sole intelligence in the cosmos, he is at least unique, and that worlds suited to intelligent life of any kind must be extremely rare. This view proves ludicrously false. In comparison with the unimaginable number of stars intelligent worlds are indeed very rare; but we discovered some thousands of worlds much like the Earth and possessed by beings of essentially human kind, though superficially they were often unlike the type that we call human. The Other Men were amongst the most obviously human. But in a later stage of our adventure, when our research was no longer restricted to worlds that had reached the familiar spiritual crisis, we stumbled on a few planets inhabited by races almost identical with Homo sapiens, or rather with the creature that Homo sapiens was in the earliest phase of his existence. These most human worlds we had not encountered earlier because, by one accident or another, they were destroyed before reaching the stage of our own mentality.

Long after we had succeeded in extending our research from our peers among the worlds to our inferiors in mental rank we remained unable to make any sort of contact with beings who had passed wholly beyond the attainment of Homo sapiens. Consequently, though we traced the history of many worlds through many epochs, and saw many reach a catastrophic end, or sink into stagnation and inevitable decline, there were a few with which, do what we would, we lost touch just at that moment when they seemed ripe for a leap forward into some more developed mentality. Not till a much later stage of our adventure, when our corporate being had itself been enriched by the influx of many superior spirits, were we able to pick up once more the threads of these most exalted world-biographies.
