The majority of the city's long-term residents were unmodified, like me, or lightly modified by reversible cyborgization, but a great many of those visiting were fabers, genetically engineered for low-gee environments. The most obvious external feature of their modification was that they had an extra pair of "arms" instead of "legs," and this meant that most of the public places in Moscoviense were designed to accommodate their kind as well as "walkers"; all the corridors were railed and all the ceilings ringed.
The sight of fabers swinging around the place like gibbons, getting everywhere at five or six times the pace of walkers, was one that I found strangely fascinating, and one to which I never quite became accustomed. Fabers couldn't live, save with the utmost difficulty, in the gravity well that was Earth; they almost never descended to the planet's surface. By the same token, it was very difficult for men from Earth to work in zero-gee environments without extensive modification, surgical if not genetic. For this reason, the only "ordinary" men who went into the true faber environments weren't ordinary by any customary standard. The Moon, with its one-sixth Earth gravity, was the only place in the inner solar system where fabers and unmodified men frequently met and mingled— there was nowhere else nearer than Ganymede.
I had always known about fabers, of course, but, like so much other "common" knowledge, the information had lain unattended in some unheeded pigeonhole of memory until direct acquaintance ignited it and gave it life. It seemed to me that fabers lived their lives at a very rapid tempo, despite the fact that they were just as emortal as members of their parent species.
For one thing, faber parents normally had their children while they were still alive, and very often had several at intervals of only twenty or thirty years! An aggregate family usually had three or even four children growing up in parallel. In the infinite reaches of space, there was no population control, and no restrictive "right of replacement." A microworld's population could grow as fast as the microworld could put on extra mass. Then again, the fabers were always doing things. Even though they had four arms, they always seemed to have trouble finding a spare hand. They seemed to have no difficulty at all in doing two different things at the same time, often using only one limb for attachment— on the Moon this generally meant hanging from the ceiling like a bat— while one hand mediated between the separate tasks being carried out by the remaining two.
I quickly realized that it wasn't just the widely accepted notion that the future of mankind must take the form of a gradual diffusion through the galaxy that made the fabers think of Earth as decadent. From their viewpoint, Earth-life seemed unbearably slow and sedentary. Unmodified mankind, having long since attained control of the ecosphere of its native world, seemed to the fabers to be living a lotus-eater existence, indolently pottering about in its spacious garden.
The fabers weren't contemptuous of legs as such, but they drew a sharp distinction between those spacefaring folk who were given legs by the genetic engineers in order to descend to the surfaces of new and alien worlds, with a job to do, and those Earthbound people who simply kept the legs their ancestors had bequeathed to them in order to enjoy the fruits of the labors of past generations.

Wherever I had lived on Earth, it had always seemed to me that one could blindly throw a stone into a crowded room and stand a fifty-fifty chance of hitting a historian of some sort. In Mare Moscoviense, the population of historians could be counted on the fingers of an unmodified man— and that in a city of a quarter of a million people. Whether they were resident or passing through, the people of the Moon were far more interested in the future than the past. When I told them about my vocation, my new neighbors were likely to smile politely and shake their heads.
"It's the weight of those legs," the fabers among them were wont to say. "You think they're holding you up, but in fact they're holding you down. Give them a chance and you'll find that you've put down roots."
If anyone told them that on Earth, "having roots" wasn't considered an altogether bad thing, they'd laugh.
"Get rid of your legs and learn to swing," they'd say. "You'll understand then that human beings have no need of roots. Only reach with four hands instead of two, and you'll find the stars within your grasp! Leave the past to rot at the bottom of the deep dark well, and give the Heavens their due."
I quickly learned to fall back on the same defensive moves most of my unmodified companions employed. "You can't break all your links with solid ground," we told the fabers, over and over again. "Somebody has to deal with the larger lumps of matter which are strewn about the universe, and you can't go to meet real mass if you don't have legs. It's planets that produce biospheres and biospheres that produce such luxuries as air. If you've seen farther than other men, it's not because you can swing by your arms from the ceiling— it's because you can stand on the shoulders of giants with legs."
Such exchanges were always cheerful. It was almost impossible to get into a real argument with a faber; their talk was as intoxicated as their movements. "Leave the wells to the unwell," they were fond of quoting. "The well will climb out of the wells, if they only find the will. History is bunk, only fit for sleeping minds."
*
A man less certain of his own destiny might have been turned aside from his task by faber banter, but I was well into my second century of life by then, and I had few doubts left regarding the propriety of my particular labor. Access to data was no more difficult on the Moon than anywhere else in the civilized Ekumen, and I proceeded, steadily and methodically, with my self-allotted task.
I made good progress there, as befitted the circumstances. Perhaps that was the happiest time of my life— but it's very difficult to draw comparisons when you're as far from childhood and youth as I now am.
Memory is an untrustworthy crutch for minds that have not yet mastered eternity.

The seventh volume of Mortimer Gray's History of Death, entitled The Last Judgment, was published on 21 June 3053. It dealt with the multiple crises that had developed in the late twentieth and twenty-first centuries, each of which and all of which had faced the human race with the prospect of extinction.
Gray described in minute detail the various nuclear exchanges which led up to Brazil's nuclear attack on Argentina in 2079 and the Plague Wars waged throughout that century. He discussed the various factors— the greenhouse crisis, soil erosion, pollution, and deforestation— that had come close to inflicting irreparable damage on the ecosphere. His map of the patterns of death in this period considered in detail the fate of the "lost billions" of peasant and subsistence farmers who were disinherited and displaced by the emergent ecological and economic order. Gray scrupulously pointed out that in less than two centuries more people had died than in the previous ten millennia. He made the ironic observation that the near-conquest of death achieved by twenty-first century medicine had created such an abundance of life as to precipitate a Malthusian crisis of awful proportions. He proposed that the new medicine and the new pestilences might be seen as different faces of the same coin, and that new technologies of food production— from the twentieth-century Green Revolution to twenty-second century tissue-culture farm factories— were as much progenitors of famine as of satiation.
Gray advanced the opinion that this was the most critical of all the stages of man's war with death. The weapons of the imagination were discarded in favor of more effective ones, but, in the short term, those more effective weapons, by multiplying life so effectively, had also multiplied death. In earlier times, the growth of human population had been restricted by lack of resources, and the war with death had been, in essence, a war of mental adaptation whose goal was reconciliation. When the "natural" checks on population growth were removed because that reconciliation was abandoned, the waste products of human society threatened to poison it. Humankind, in developing the weapons by which the long war with death might be won, had also developed— in a more crudely literal sense— the weapons by which it
might be lost. Nuclear arsenals and stockpiled AIDS viruses were scattered all over the globe: twin pistols held in the skeletal hands of death, leveled at the entire human race. The wounds they inflicted could so easily have been mortal— but the dangerous corner had, after all, been turned. The sciences of life, having passed through a particularly desperate stage of their evolution, kept one vital step ahead of the problems that they had helped to generate. Food technology finally achieved a merciful divorce from the bounty of nature, moving out of the fields and into the factories to achieve a complete liberation of man from the vagaries of the ecosphere, and paving the way for Garden Earth.
Gray argued that this was a remarkable triumph of human sanity which produced a political apparatus enabling human beings to take collective control of themselves, allowing the entire world to be managed and governed as a whole. He judged that the solution was far from Utopian, and that the political apparatus in question was at best a ramshackle and ill-designed affair, but admitted that it did the job. He emphasized that in the final analysis it was not scientific progress per se which had won the war against death, but the ability of human beings to work together, to compromise, to build communities. That human beings possessed this ability was, he argued, as much the legacy of thousands of years of superstition and religion as of hundreds of years of science.
The Last Judgment attracted little critical attention, as it was widely held to be dealing with matters that everyone understood very well. Given that the period had left an abundant legacy of archival material of all kinds, Gray's insistence on using only mute text accompanied by still photographs seemed to many commentators to be pedestrian and frankly perverse, unbecoming a true historian.

In twenty years of living beneath a star-filled sky, I was strongly affected by the magnetic pull that those stars seemed to exert upon my spirit. I seriously considered applying for modification for low-gee and shipping out from Mare Moscoviense along with the emigrants to some new microworld, or perhaps going out to one of the satellites of Saturn or Uranus, to a world where the sun's bountiful radiance was of little consequence and men lived entirely by the fruits of their own efforts and their own wisdom.
But the years drifted by, and I didn't go.
Sometimes I thought of this failure as a result of cowardice, or evidence of the decadence that the fabers and other subspecies attributed to the humans of Earth. I sometimes imagined myself as an insect born at the bottom of a deep cave, who had— thanks to the toil of many preceding generations of insects— been brought to the rim from which I could look out at the great world, but who dared not take the one final step that would carry me out and away. More and more, however, I found my thoughts turning back to the Earth. My memories of its many environments became gradually fonder the longer my absence lasted. Nor could I despise this as a weakness. Earth was, after all, my home. It was not only my world, but the home world of all humankind. No matter what the fabers and their kin might say, the Earth was and would always remain an exceedingly precious thing, which should never be abandoned.
It seemed to me then— and still seems now— that it would be a terrible thing were men to spread themselves across the entire galaxy, taking a multitude of forms in order to occupy a multitude of alien worlds, and in the end forget entirely the world from which their ancestors had sprung.

Once, I was visited in Mare Moscoviense by Khan Mirafzal, the faber with whom I had long ago debated on TV, and talked with again before my emigration. His home, for the moment, was a microworld in the asteroid belt that was in the process of being fitted with a drive that would take it out of the system and into the infinite. He was a kind and even-tempered man who would not dream of trying to convince me of the error of my ways, but he was also a man with a sublime vision who could not restrain his enthusiasm for his own chosen destiny.
"I have no roots on Earth, Mortimer, even in a metaphorical sense. In my being, the chains of adaptation have been decisively broken. Every man of my kind is born anew, designed and synthesized; we are self-made men, who belong everywhere and nowhere. The wilderness of empty space which fills the universe is our realm, our heritage. Nothing is strange to us, nothing foreign, nothing alien. Blastular engineering has incorporated freedom into our blood and our bones, and I intend to take full advantage of that freedom. To do otherwise would be a betrayal of my nature."
"My own blastular engineering served only to complete the adaptation to life on Earth which natural selection had left incomplete," I reminded him. "I'm no new man, free from the ties which bind me to the Earth."
"Not so," he replied. "Natural selection would never have devised emortality, for natural selection can only generate change by death and replacement. When genetic engineers found the means of setting aside the curse of aging, they put an end to natural selection forever. The first and greatest freedom is time, my friend, and you have all the time in the world. You can become whatever you want to be. What do you want to be, Mortimer?"
"An historian," I told him. "It's what I am because it's what I want to be."
"All well and good— but history isn't inexhaustible, as you well know. It ends with the present day, the present moment. The future, on the other hand…"
"Is given to your kind. I know that, Mira. I don't dispute it. But what exactly is your kind, given that you rejoice in such freedom to be anything you want to be? When the starship Pandora effected the first meeting between humans and a ship that set out from another star system, the crews of the two ships, each consisting entirely of individuals bioengineered for life in zero-gee, resembled one another far more than they resembled unmodified members of their parent species. The fundamental chemistries controlling their design were different, but this only led to the faber crews trading their respective molecules of life, so that their genetic engineers could henceforth make and use chromosomes of both kinds. What kind of freedom is it that makes all the travelers of space into mirror images of one another?"
"You're exaggerating," Mirafzal insisted. "The news reports played up the similarity, but it really wasn't as close as all that. Yes, the Pandora encounter can't really be regarded as a first contact between humans and aliens, because the distinction between human and alien had ceased to carry any real meaning long before it happened. But it's not the case that our kind of freedom breeds universal mediocrity because adaptation to zero-gee is an existential straitjacket. We've hardly scratched the surface of constructive cyborgization, which will open up a whole new dimension of freedom."
"That's not for me," I told him. "Maybe it is just my legs weighting me down, but I'm well and truly addicted to gravity. I can't cast off the past like a worn-out surskin. I know you think I ought to envy you, but I don't. I daresay you think that I'm clinging like a terrified infant to Mother Earth while you're achieving true maturity, but I really do think it's important to have somewhere to belong."
"So do I," the faber said, quietly. "I just don't think that Earth is or ought to be that place. It's not where you start from that's important, Mortimer, it's where you're going."
"Not for an historian."
"For everybody. History ends, Mortimer, life doesn't— not anymore."
*
I was at least half-convinced that Khan Mirafzal was right, although I didn't follow his advice. I still am. Maybe I was and am trapped in a kind of infancy, or a kind of lotus-eater decadence— but if so, I could see no way out of the trap then, and I still can't.
Perhaps things would have turned out differently if I'd had one of my close encounters with death while I was on the Moon, but I didn't. The dome in which I lived was only breached once, and the crack was sealed before there was any significant air-loss. It was a scare, but it wasn't a threat. Perhaps, in the end, the Moon was too much like Antarctica— but without the crevasses. Fortune seems to have decreed that all my significant formative experiences have to do with water, whether it be very hot or very, very cold.
Eve
ntually, I gave in to my homesickness for Garden Earth and returned there, having resolved not to leave it again until my history of death was complete. I never did.

The eighth volume of Mortimer Gray's History of Death, entitled The Fountains of Youth, was published on 1 December 3064. It dealt with the development of elementary technologies of longevity and elementary technologies of cyborgization in the twenty-fourth and twenty-fifth centuries. It tracked the progress of the new "politics of immortality," whose main focus was the new Charter of Human Rights, which sought to establish a basic right to longevity for all. It also described the development of the Zaman transformations by which human blastulas could be engineered for longevity, which finally opened the way for the wholesale metamorphosis of the human race.
According to Gray, the Manifesto of the New Chartists was the vital treaty which ushered in a new phase in man's continuing war with death, because it defined the whole human community as a single army, united in all its interests. He quoted with approval and reverence the opening words of the document: "Man is born free, but is everywhere enchained by the fetters of death. In all times past, men have been truly equal in one respect and one only: they have all borne the burden of age and decay. The day must soon dawn when this burden can be set aside; there will be a new freedom, and with this freedom must come a new equality. No man has the right to escape the prison of death while his fellows remain shackled within."
Gray carefully chronicled the long battle fought by the Chartists across the stage of world politics, describing it with a partisan fervor that had been largely absent from his work since the fourth volume. There was nothing clinical about his description of the "persecution" of Ali Zaman and the resistance offered by the community of nations to his proposal to make future generations truly emortal. Gray admitted that he had the benefits of hindsight, and that as a Zaman-transformed individual himself, he was bound to have an attitude very different from Zaman's confused and cautious contemporaries, but he saw no reason to be entirely evenhanded. From his viewpoint, those who initially opposed Zaman were traitors in the war against death, and he could find few excuses for them. In trying to preserve "human nature" against biotechnological intervention— or, at least, to confine such interventions by a mythos of medical "repair" —those men and women had, in his stern view, been willfully blind and negligent of the welfare of their own children.
