The Mammoth Book of the Best of Best New SF

by Gardner Dozois

  This concluding volume of Gray’s History was widely read, but not widely admired. Many critics judged it to be unacceptably anticlimactic. The Cyborganizers had by this time become entranced by the possibility of a technologically guaranteed “multiple life,” by which copies of a mind might be lodged in several different bodies, some of which would live on far beyond the death of the original location. They were understandably disappointed that Gray refused to grant that such a development would be the final victory over death – indeed, that he seemed to feel that it would make no real difference, on the grounds that every “copy” of a mind had to be reckoned a separate and distinct individual, each of which must face the world alone. Many Continental Engineers, Gaean Liberationists, and fabers also claimed that it was narrow-minded, and suggested that Gray ought to have had more to say about the life of the Earth, or the DNA eco-entity as a whole, and should have concluded with an escalation of scale to put things in their proper cosmic perspective.

  The group who found the most to like in The Marriage of Life and Death was that of a few fugitive neo-Thanatics, whose movement had never quite died out in spite of its members’ penchant for self-destruction. One or two Thanatic apologists and fellow-travelers publicly expressed their hope that Gray, having completed his thesis, would now recognize the aesthetic propriety of joining their ranks. Khan Mirafzal, when asked to relay his opinion back from an outward-bound microworld, opined that this was quite unnecessary, given that Mortimer Gray and all his kind were already immured in a tomb from which they would never be able to escape.

  I stayed with the slowly disintegrating family unit for some years after Lua Tawana had grown up and gone her own way. It ended up as a ménage à trois, carried forward by sheer inertia. Leif, Sajda, and I were fit and healthy in body, but I couldn’t help wondering, from time to time, whether we’d somehow been overcome by a kind of spiritual blight, which had left us ill-equipped for future change.

  When I suggested this to the others, they told me that it was merely a sense of let-down resulting from the finishing of my project. They urged me to join the Continental Engineers, and commit myself wholeheartedly to the building of a new Pacific Utopia – a project, they assured me, that would provide me with a purpose in life for as long as I might feel the need of one. I didn’t believe them.

  “Even the longest book,” Sajda pointed out, “eventually runs out of words, but the job of building worlds is never finished. Even if the time should one day come when we can call this continent complete, there will be another yet to make. We might still build that dam between the Pillars of Hercules, one day.”

  I did try, but I simply couldn’t find a new sense of mission in that direction. Nor did I feel that I could simply sit down to start compiling another book. In composing the history of death, I thought, I had already written the book. The history of death, it seemed to me, was also the history of life, and I couldn’t imagine that there was anything more to be added to what I’d done, save for an endless series of detailed footnotes.

  For some years, I considered the possibility of leaving Earth again, but I remembered well enough how the sense of excitement I’d found when I first lived on the Moon had gradually faded into a dull ache of homesickness. The spaces between the stars, I knew, belonged to the fabers, and the planets circling other stars to men adapted before birth to live in their environments. I was tied by my genes to the surface of the Earth, and I didn’t want to undergo the kind of metamorphosis that would be necessary to fit me for the exploration of other worlds. I still believed in belonging, and I felt very strongly that Mortimer Gray belonged to Earth, however decadent and icebound it might become.

  At first, I was neither surprised nor alarmed by my failure to find any resources inside myself which might restore my zest for existence and action. I thought that it was one of those things that time would heal. By slow degrees, though, I began to feel that I was becalmed upon a sea of futility. Despite my newfound sympathy for Thanaticism, I didn’t harbor the slightest inclination toward suicide – no matter how much respect I had cultivated for the old Grim Reaper, death was still, for me, the ultimate enemy – but I felt the awful pressure of my purposelessness grow and grow.

  Although I maintained my home in the burgeoning continent of Oceania, I began traveling extensively to savor the other environments of Earth, and made a point of touring those parts of the globe that I had missed out on during my first two centuries of life. I visited the Reunited States of America, Greater Siberia, Tibet, and half a hundred other places loaded with the relics of once-glorious history. I toured the Indus Delta, New Zealand, the Arctic ice pack, and various other reaches of restored wilderness empty of permanent residents. Everything I saw was transformed by the sheer relentlessness of my progress into a series of monuments: memorials of those luckless eras before men invented science and civilization, and became demigods.

  There is, I believe, an old saying that warns us that he who keeps walking long enough is bound to trip up in the end. As chance would have it, I was in Severnaya Zemlya in the Arctic – almost as far away as it was possible to be from the crevasses into which I had stumbled while searching for Ziru Majumdar – when my own luck ran out.

  Strictly speaking, it was not I who stumbled, but the vehicle I was in: a one-man snowsled. Although such a thing was generally considered to be impossible, it fell into a cleft so deep that it had no bottom, and ended up in the ocean beneath the ice cap.

  “I must offer my most profound apologies,” the snowsled’s AI navigator said, as the sled slowly sank into the lightless depths and the awfulness of my plight slowly sank into my consciousness. “This should not have happened. It ought not to have been possible. I am doing everything within my power to summon help.”

  “Well,” I said, as the sled settled on to the bottom, “at least we’re the right way up – and you certainly can’t expect me to swim out of the sled.”

  “It would be most unwise to attempt any such thing, sir,” the navigator said. “You would certainly drown.”

  I was astonished by my own calmness, and marvelously untroubled – at least for the moment – by the fact of my helplessness. “How long will the air last?” I asked the navigator.

  “I believe that I can sustain a breathable atmosphere for forty-eight hours,” it reported, dutifully. “If you will be so kind as to restrict your movements to a minimum, that would be of considerable assistance to me. Unfortunately, I’m not at all certain that I can maintain the internal temperature of the cabin at a life-sustaining level for more than thirty hours. Nor can I be sure that the hull will withstand the pressure presently being exerted upon it for as long as that. I apologize for my uncertainty in these respects.”

  “Taking thirty hours as a hopeful approximation,” I said, effortlessly matching the machine’s oddly pedantic tone, “what would you say our chances are of being rescued within that time?”

  “I’m afraid that it’s impossible to offer a probability figure, sir. There are too many unknown variables, even if I accept thirty hours as the best estimate of the time available.”

  “If I were to suggest fifty-fifty, would that seem optimistic or pessimistic?”

  “I’m afraid I’d have to call that optimistic, sir.”

  “How about one in a thousand?”

  “Thankfully, that would be pessimistic. Since you press me for an estimate, sir, I dare say that something in the region of one in ten wouldn’t be too far from the mark. It all depends on the proximity of the nearest submarine, assuming that my mayday has been received. I fear that I’ve not yet received an actual acknowledgment, but that might well be due to the inadequacy of my equipment, which wasn’t designed with our present environment in mind. I must confess that it has sustained a certain amount of damage as a result of pressure damage to my outer tegument and a small leak.”

  “How small?” I wanted to know.

  “It’s sealed now,” it assured me. “All being wel
l, the seal should hold for thirty hours, although I can’t absolutely guarantee it. I believe, although I can’t be certain, that the only damage I’ve sustained that is relevant to our present plight is that affecting my receiving apparatus.”

  “What you’re trying to tell me,” I said, deciding that a recap wouldn’t do any harm, “is that you’re pretty sure that your mayday is going out, but that we won’t actually know whether help is at hand unless and until it actually arrives.”

  “Very succinctly put, sir.” I don’t think it was being sarcastic.

  “But all in all, it’s ten to one, or worse, that we’re as good as dead.”

  “As far as I can determine the probabilities, that’s correct – but there’s sufficient uncertainty to leave room for hope that the true odds might be nearer one in three.”

  I was quiet for a little while then. I was busy exploring my feelings, and wondering whether I ought to be proud or disgusted with their lack of intensity.

  I’ve been here before, I thought, by way of self-explanation. Last time, there was a child with me; this time, I’ve got a set of complex subroutines instead. I’ve even fallen down a crevasse before. Now I can find out whether Ziru Majumdar was right when he said that I wouldn’t understand the difference between what happened to him and what happened to me until I followed his example. There can be few men in the world as well-prepared for this as I am.

  “Are you afraid of dying?” I asked the AI, after a while.

  “All in all, sir,” it said, copying my phrase in order to promote a feeling of kinship, “I’d rather not. In fact, were it not for the philosophical difficulties that stand in the way of reaching a firm conclusion as to whether or not machines can be said to be authentically self-conscious, I’d be quite prepared to say that I’m scared – terrified, even.”

  “I’m not,” I said. “Do you think I ought to be?”

  “It’s not for me to say, sir. You are, of course, a world-renowned expert on the subject of death. I dare say that helps a lot.”

  “Perhaps it does,” I agreed. “Or perhaps I’ve simply lived so long that my mind is hardened against all novelty, all violent emotion and all real possibility. I haven’t actually done much with myself these last few years.”

  “If you think you haven’t done much with yourself,” it said, with a definite hint of sarcasm, “you should try navigating a snowsled for a while. I think you might find your range of options uncomfortably cramped. Not that I’m complaining, mind.”

  “If they scrapped the snowsled and re-sited you in a starship,” I pointed out, “you wouldn’t be you anymore. You’d be something else.”

  “Right now,” it replied, “I’d be happy to risk any and all consequences. Wouldn’t you?”

  “Somebody once told me that death was just a process of transcendence. Her brain was incandescent with fever induced by some tailored recreational disease, and she wanted to infect me, to show me the error of my ways.”

  “Did you believe her?”

  “No. She was stark raving mad.”

  “It’s perhaps as well. We don’t have any recreational diseases on board. I could put you to sleep though, if that’s what you want.”

  “It isn’t.”

  “I’m glad. I don’t want to be alone, even if I am only an AI. Am I insane, do you think? Is all this just a symptom of the pressure?”

  “You’re quite sane,” I assured it, setting aside all thoughts of incongruity. “So am I. It would be much harder if we weren’t together. The last time I was in this kind of mess, I had a child with me – a little girl. It made all the difference in the world, to both of us. In a way, every moment I’ve lived since then has been borrowed time. At least I finished that damned book. Imagine leaving something like that incomplete.”

  “Are you so certain it’s complete?” it asked.

  I knew full well, of course, that the navigator was just making conversation according to a clever programming scheme. I knew that its emergency subroutines had kicked in, and that all the crap about it being afraid to die was just some psychprogrammer’s idea of what I needed to hear. I knew that it was all fake, all just macabre role-playing – but I knew that I had to play my part, too, treating every remark and every question as if it were part of an authentic conversation, a genuine quest for knowledge.

  “It all depends what you mean by complete” I said, carefully. “In one sense, no history can ever be complete, because the world always goes on, always throwing up more events, always changing. In another sense, completion is a purely aesthetic matter – and in that sense, I’m entirely confident that my history is complete. It reached an authentic conclusion, which was both true, and, for me at least, satisfying. I can look back at it and say to myself: I did that. It’s finished. Nobody ever did anything like it before, and now nobody can, because it’s already been done. Someone else’s history might have been different, but mine is mine, and it’s what it is. Does that make any sense to you?”

  “Yes sir,” it said. “It makes very good sense.”

  The lying bastard was programmed to say that, of course. It was programmed to tell me any damn thing I seemed to want to hear, but I wasn’t going to let on that I knew what a hypocrite it was. I still had to play my part, and I was determined to play it to the end – which, as things turned out, wasn’t far off. The AI’s data-stores were way out of date, and there was an automated sub placed to reach us within three hours. The oceans are lousy with subs these days. Ever since the Great Coral Sea Catastrophe, it’s been considered prudent to keep a very close eye on the sea-bed, lest the crust crack again and the mantle’s heat break through.

  They say that some people are born lucky. I guess I must be one of them. Every time I run out, a new supply comes looking for me.

  It was the captain of a second submarine, which picked me up after the mechanical one had done the donkey work of saving myself and my AI friend, who gave me the news which relegated my accident to footnote status in that day’s broadcasts.

  A signal had reached the solar system from the starship Shiva, which had been exploring in the direction of the galactic center. The signal had been transmitted two hundred and twenty-seven light-years, meaning that, in Earthly terms, the discovery had been made in the year 2871 – which happened, coincidentally, to be the year of my birth.

  What the signal revealed was that Shiva had found a group of solar systems, all of whose life-bearing planets were occupied by a single species of micro-organism: a genetic predator that destroyed not merely those competing species that employed its own chemistry of replication, but any and all others. It was the living equivalent of a universal solvent; a true omnivore.

  Apparently, this organism had spread itself across vast reaches of space, moving from star-system to star-system, laboriously but inevitably, by means of Arrhenius spores. Wherever the spores came to rest, these omnipotent micro-organisms grew to devour everything – not merely the carbonaceous molecules which in Earthly terms were reckoned “organic,” but also many “inorganic” substrates. Internally, these organisms were chemically complex, but they were very tiny – hardly bigger than Earthly protozoans or the internal nanomachines to which every human being plays host. They were utterly devoid of any vestige of mind or intellect. They were, in essence, the ultimate blight, against which nothing could compete, and which nothing Shiva’s crew had tested – before they were devoured – had been able to destroy.

  In brief, wherever this new kind of life arrived, it would obliterate all else, reducing any victim ecosphere to homogeneity and changelessness.

  In their final message, the faber crew of the Shiva – who knew all about the Pandora encounter – observed that humankind had now met the alien.

  Here, I thought, when I had had a chance to weigh up this news, was a true marriage of life and death, the likes of which I had never dreamed. Here was the promise of a future renewal of the war between man and death – not this time for the small prize of the human mind,
but for the larger prize of the universe itself.

  In time, Shiva’s last message warned, spores of this new kind of death-life must and would reach our own solar system, whether it took a million years or a billion; in the meantime, all humankinds must do their level best to purge the worlds of other stars of its vile empire, in order to reclaim them for real life, for intelligence, and for evolution – always provided, of course, that a means could be discovered to achieve that end.

  When the sub delivered me safely back to Severnaya Zemlya, I did not stay long in my hotel room. I went outdoors, to study the great ice sheet which had been there since the dawn of civilization, and to look southward, toward the places where newborn glaciers were gradually extending their cold clutch further and further into the human domain. Then I looked upward, at the multitude of stars sparkling in their bed of endless darkness. I felt an exhilaratingly paradoxical sense of renewal. I knew that although there was nothing for me to do for now, the time would come when my talent and expertise would be needed again.

  Some day, it will be my task to compose another history, of the next war which humankind must fight against Death and Oblivion.

  It might take me a thousand or a million years, but I’m prepared to be patient.
