He was in the middle of a perfectly ordinary life when they drafted him and sent him to Mars.

The summons came in the form of a fax that appeared out of his phone, in the apartment Art Randolph had rented just the month before, after he and his wife had decided on a trial separation. The fax was brief: Dear Arthur Randolph: William Fort invites you to attend a private seminar. A plane will leave San Francisco airport at 9 A.M., February 22nd 2101.

Art stared at the paper in amazement. William Fort was the founder of Praxis, the transnational that had acquired Art’s company some years before. Fort was very old, and now his position in the transnat was said to be some kind of semiretired emeritus thing. But he still held private seminars, which were notorious although there was very little hard information about them. It was said that he invited people from all subsidiaries of the transnat; that they gathered in San Francisco, and were flown away by private jet to someplace secret. No one knew what went on there. People who attended were usually transferred afterward, and if not, they kept their mouths shut in a way that gave one pause. So it was a mystery.

Art was surprised to be invited, apprehensive but basically pleased. Before its acquisition he had been the cofounder and technical director of a small company called Dumpmines, which was in the business of digging up and processing old landfills, recovering the valuable materials that had been thrown away in a more wasteful age. It had been a surprise when Praxis had acquired them, a very pleasant surprise, as everyone in Dumpmines went from employment in a small firm to apprentice membership in one of the richest organizations in the world— paid in its shares, voting on its policy, free to use all its resources. It was like being knighted.

Art certainly had been pleased, and so had his wife, although she had been elegiac as well. She herself had been hired by Mitsubishi’s synthesis management, and the big transnationals, she said, were like separate worlds. With the two of them working for different ones they were inevitably going to drift apart, even more than they already had. Neither of them needed the other anymore to obtain longevity treatments, which transnats provided much more reliably than the government. And so they were like people on different ships, she said, sailing out of San Francisco Bay in different directions. Like ships, in fact, passing in the night.

It had seemed to Art that they might have been able to commute between ships, if his wife had not been so interested in one of the other passengers on hers, a vice-chairman of Mitsubishi in charge of East Pacific development. But Art had been quickly caught up in Praxis’s arbitration program, traveling frequently to take classes or arbitrate in disputes between various small Praxis subsidiaries involved in resource recovery, and when he was in San Francisco, Sharon was very seldom at home. Their ships were moving out of hailing distance, she had said, and he had become too demoralized to contest the point, and had moved out soon afterward, on her suggestion. Kicked out, one could have said.

Now he rubbed a swarthy unshaven jaw, rereading the fax for the fourth time. He was a big man, powerfully built but with a tendency to slouch—”uncouth,” his wife had called him, although his secretary at Dumpmines used the term “bearlike,” which he preferred. Indeed he had the somewhat clumsy and shambling appearance of a bear, also its surprising quickness and power. He had been a fullback at the University of Washington, a fullback slow of foot but decisive in direction, and very difficult to bring down. Bear Man, they had called him. Tackle him at your peril.

He had studied engineering, and afterward worked in the oil fields of Iran and Georgia, devising a number of innovations for extracting oil from extremely marginal shale. He had gotten a master’s degree from Tehran University while doing this work, and then had moved to California and joined a friend who was forming a company that made deep-sea diving equipment used in offshore oil drilling, an enterprise that was moving out into ever-deeper water as more accessible supplies were exhausted. Once again Art had invented a number of improvements in both diving gear and underwater drills, but a couple of years spent in compression chambers and on the continental shelf had been enough for him, and he had sold his shares to his partner and moved on again. In quick succession he had started a cold-environments habitat construction company, worked for a solar panel firm, and built rocket gantries. Each job had been fine, but as time passed he had found that what really interested him was not the technical problems but the human ones. He became more and more involved with project management, and then got into arbitration; he liked jumping into arguments and solving them to everyone’s satisfaction. It was engineering of a different kind, more engrossing and fulfilling than the mechanical stuff, and more difficult. Several of the companies he worked for in those years were part of transnationals, and he got embroiled in interface arbitration not only between his companies and others in the transnats, but also in more distant disputes requiring some kind of third-party arbitration. Social engineering, he called it, and found it fascinating.

So when starting Dumpmines he had taken the technical directorship, and had done some good work on their SuperRathjes, the giant robot vehicles that did the extraction and sorting at the landfills; but more than ever before he involved himself in labor disputes and the like. This trend in his career had accelerated after the acquisition by Praxis. And on the days when work like that went well, he always went home knowing that he should have been a judge, or a diplomat. Yes— at heart he was a diplomat.

Which made it embarrassing that he had not been able to negotiate a successful outcome to his own marriage. And no doubt the breakup was well known to Fort, or whoever had invited him to this seminar. It was even possible that they had bugged his old apartment, and heard the unhappy mess of his and Sharon’s final months together, which wouldn’t have been flattering to either of them. He cringed at the thought, still rubbing his rough jaw, and drifted toward the bathroom and turned on the portable water heater. The face in the mirror looked mildly stunned. Unshaven, fifty, separated, misemployed for most of his life, just beginning at his true calling— he was not the kind of person he imagined got faxes from William Fort.

His wife or ex-wife-to-be called, and she was likewise incredulous. “It must be a mistake,” she said when Art told her about it.

She had called about one of her camera lenses, now missing; she suspected that Art had taken it when he moved out. “I’ll look for it,” Art said. He went over to the closet to look in his two suitcases, still packed. He knew the lens was not in them, but he rooted loudly through them both anyway. Sharon would know if he tried to fake it. While he searched she continued to talk over the phone, her voice echoing tinnily through the empty apartment. “It just shows how weird that Fort is. You’ll go to some Shangri-La and he’ll be using Kleenex boxes for shoes and talking Japanese, and you’ll be sorting his trash and learning to levitate and I’ll never see you again. Did you find it?”

“No. It’s not here.” When they had separated they had divided their joint possessions: Sharon had taken their apartment, the entertainment center, the desktop array, the lectern, the cameras, the plants, the bed, and all the rest of the furniture; Art had taken the Teflon frying pan. Not one of his best arbitrations. But it meant he now had very few places to search for the lens.

Sharon could make a single sigh into a comprehensive accusation. “They’ll teach you Japanese, and we’ll never see you again. What could William Fort want with you?”

“Marriage counseling?” Art said.

• • •

Many of the rumors about Fort’s seminars turned out to be true, which Art found amazing. At San Francisco International he got on a big powerful private jet with six other men and women, and after takeoff the jet’s windows, apparently double-polarized, went black, and the door to the cockpit was closed. Two of Art’s fellow passengers played at orienteering, and after the jet made several gentle banks left and right, they agreed that they were headed in some direction between southwest and north. The seven of them shared information: they were all technical managers or arbitrators from the vast network of Praxis companies. They had flown in to San Francisco from all over the world. Some seemed excited to be invited to meet the transnational’s reclusive founder; others were apprehensive.

Their flight lasted six hours, and the orienteers spent the descent plotting the outermost limit of their location, a circle that encompassed Juneau, Hawaii, Mexico City, and Detroit, although it could have been larger, as Art pointed out, if they were in one of the new air-to-space jets; perhaps half the Earth or more. When the jet landed and stopped, they were led through a miniature jetway into a big van with blackened windows, and a windowless barrier between them and the driver’s seat. Their doors were locked from the outside.

They were driven for half an hour. Then the van stopped and they were let out by their driver, an elderly man wearing shorts and a T-shirt advertising Bali.

They blinked in the sunlight. They were not in Bali. They were in a small asphalt parking lot surrounded by eucalyptus trees, at the bottom of a narrow coastal valley. An ocean or very big lake lay to the west about a mile, just a small wedge of it in sight. A creek drained the valley, and ran into a lagoon behind a beach. The valley’s side walls were covered with dry grass on the south side, cactus on the north; the ridges above were dry brown rock. “Baja?” one of the orienteers guessed. “Ecuador? Australia?”

“San Luis Obispo?” Art said.

• • •

Their driver led them on foot down a narrow road to a small compound, composed of seven two-story wooden buildings, nestled among seacoast pines at the bottom of the valley. Two buildings by the creek were residences, and after they dropped their bags in assigned rooms in these buildings, the driver led them to a dining room in another building, where half a dozen kitchen workers, all quite elderly, fed them a simple meal of salad and stew. After that they were taken back to the residences, and left on their own.

They gathered in a central chamber around a wood-burning stove. It was warm outside, and there was no fire in the stove.

“Fort is a hundred and twelve,” the orienteer named Sam said. “And the treatments haven’t worked on his brain.”

“They never do,” said Max, the other orienteer.

They discussed Fort for a while. All of them had heard things, for William Fort was one of the great success stories in the history of medicine, their century’s Pasteur: the man who beat cancer, as the tabloids inaccurately put it. The man who beat the common cold. He had founded Praxis at age twenty-four, to market several breakthrough innovations in antivirals, and he had been a multi-billionaire by the time he was twenty-seven. After that he had occupied his time by expanding Praxis into one of the world’s biggest transnationals. Eighty continuous years of metastasizing, as Sam put it. While mutating personally into a kind of ultra-Howard Hughes, or so it was said, growing more and more powerful, until like a black hole he had disappeared completely inside the event horizon of his own power. “I just hope it doesn’t get too weird,” Max said.

The others attendants— Sally, Amy, Elizabeth, and George— were more optimistic. But all of them were apprehensive at their peculiar welcome, or lack of one, and when no one came to visit them through the rest of that evening, they retired to their rooms looking concerned.

• • •

Art slept well as always, and at dawn he woke to the low hoot of an owl. The creek burbled below his window. It was a gray dawn, the air filled with the fog that nourished the sea pines. A tocking sound came from somewhere in the compound.

He dressed and went out. Everything was soaking wet. Down on narrow flat terraces below the buildings were rows of lettuce, and rows of apple trees so pruned and tied to frameworks that they were no more than fan-shaped bushes.

Colors were seeping into things when Art came to the bottom of the little farm, over the lagoon. There a lawn lay spread like a carpet under a big old oak tree. Art walked over to the tree, feeling drawn to it. He touched its rough, fissured bark. Then he heard voices; coming up a path by the lagoon were a line of people, wearing black wetsuits and carrying surfboards, or long folded birdsuits. As they passed he recognized the faces of the previous night’s kitchen crew, and also their driver. The driver waved and continued up the path. Art walked down it to the lagoon. The low sound of waves mumbled through the salty air, and birds swam in the reeds.

After a while Art went back up the trail, and in the compound’s dining room he found the elderly workers back in the kitchen, flipping pancakes. After Art and the rest of the guests had eaten, yesterday’s driver led them upstairs to a large meeting room. They sat on couches arranged in a square. Big picture windows in all four walls let in a lot of the morning’s gray light. The driver sat on a chair between two couches. “I’m William Fort,” he said. “I’m glad you’re all here.”

• • •

He was, on closer inspection, a strange-looking old man; his face was lined as if by a hundred years of anxiety, but the expression it currently displayed was serene and detached. A chimp, Art thought, with a past in lab experimentation, now studying Zen. Or simply a very old surfer or hang-glider, weathered, bald, round-faced, snub-nosed. Now taking them in one by one. Sam and Max, who had ignored him as driver and cook, were looking uncomfortable, but he didn’t seem to notice. “One index,” he said, “for measuring how full the world is of humans and their activities, is the percent appropriation of the net product of land-based photosynthesis.”

Sam and Max nodded as if this were the usual way to start a meeting.

“Can I take notes?” Art asked.

“Please,” Fort said. He gestured at the coffee table in the middle of the square of couches, which was covered with papers and lecterns. “I want to play some games later, so there’s lecterns and workpads, whatever you like.”

Most of them had brought their own lecterns, and there was a short silent scramble as they got them out and running. While they were at it Fort stood up and began walking in a circle behind their couches, making a revolution every few sentences. Difficult! Art wrote. Continued?

“We now use about eighty percent of the net primary product of land-based photosynthesis,” he said. “One hundred percent is probably impossible to reach, and our long-range carrying capacity has been estimated to be thirty percent, so we are massively overshot, as they say. We have been liquidating our natural capital as if it were disposable income, and are nearing depletion of certain capital stocks, like oil, wood, soil, metals, fresh water, fish, and animals. This makes continued economic expansion difficult.”

“We have to continue,” Fort said, with a piercing glance at Art, who unobtrusively sheltered his lectern with his arm. “Continuous expansion is a fundamental tenet of economics. Therefore one of the fundamentals of the universe itself. Because everything is economics. Physics is cosmic economics, biology is cellular economics, the humanities are social economics, psychology is mental economics, and so on.”

His listeners nodded unhappily.

“So everything is expanding. But it can’t happen in contradiction to the law of conservation of matter-energy. No matter how efficient your throughput is, you can’t get an output larger than the input.”

Art wrote on his note page, Output larger than input— everything economics— natural capital— Massively Overshot.

“In response to this situation, a group here in Praxis has been working on what we call full-world economics.”

“Shouldn’t that be overfull-world?” Art asked.

Fort didn’t appear to hear him. “Now as Daly said, man-made capital and natural capital are not substitutable. This is obvious, but since most economists still say they are substitutable, it has to be insisted on. Put simply, you can’t substitute more sawmills for fewer forests. If you’re building a house you can juggle the number of power saws and carpenters, which means they’re substitutable, but you can’t build it with half the amount of lumber, no matter how many saws or carpenters you have. Try it and you have a house of air. And that’s where we live now.”

Art shook his head and looked down at his lectern page, which he had filled again. Resources and capital nonsubstitutable— power saws/carpenters— house of air.

“Excuse me?” Sam said. “Did you say natural capital?”

Fort jerked, turned around to look at Sam. “Yes?”

“I thought capital was by definition man-made. The produced means of production, we were taught to define it.”

“Yes. But in a capitalist world, the word capital has taken on more and more uses. People talk about human capital, for instance, which is what labor accumulates through education and work experience. Human capital differs from the classic kind in that you can’t inherit it, and it can only be rented, not bought or sold.”

“Unless you count slavery,” Art said.

Fort’s forehead wrinkled. “This concept of natural capital actually resembles the traditional definition more than human capital. It can be owned and bequeathed, and divided into renewable and nonrenewable, marketed and nonmarketed.”

“But if everything is capital of one sort or another,” Amy said, “you can see why people would think that one kind was substitutable for another kind. If you improve your man-made capital to use less natural capital, isn’t that a substitution?”

Fort shook his head. “That’s efficiency. Capital is a quantity of input, and efficiency is a ratio of output to input. No matter how efficient capital is, it can’t make something out of nothing.”

“New energy sources . . .” Max suggested.

“But we can’t make soil out of electricity. Fusion power and self-replicating machinery have given us enormous amounts of power, but we have to have basic stocks to apply that power to. And that’s where we run into a limit for which there are no substitutions possible.”

Fort stared at them all, still displaying that primate calm that Art had noted at the beginning. Art glanced at his lectern screen. Natural capital— human capital— traditional capital— energy vs. matter— electric soil— no substitutes please— He grimaced and clicked to a new page.

Fort said, “Unfortunately, most economists are still working within the empty-world model of economics.”

“The full-world model seems obvious,” Sally said. “It’s just common sense. Why would any economist ignore it?”

Fort shrugged, made another silent circumnavigation of the room. Art’s neck was getting tired.

“We understand the world through paradigms. The change from empty-world economics to full-world economics is a major paradigm shift. Max Planck once said that a new paradigm takes over not when it convinces its opponents, but when its opponents eventually die.”

“And now they aren’t dying,” Art said.

Fort nodded. “The treatments are keeping people around. And a lot of them have tenure.”

Sally looked disgusted. “Then they’ll have to learn to change their minds, won’t they.”

Fort stared at her. “We’ll try that right now. In theory at least. I want you to invent full-world economic strategies. It’s a game I play. If you plug your lecterns into the table, I can give you the starting data.”

They all leaned forward and plugged into the table.

• • •

The first game Fort wanted to play involved estimating maximum sustainable human populations. “Doesn’t that depend on assumptions about lifestyle?” Sam asked.

“We’ll make a whole range of assumptions.”

He wasn’t kidding. They went from scenarios in which Earth’s every acre of arable land was farmed with maximum efficiency, to scenarios involving a return to hunting and gathering; from universal conspicuous consumption, to universal subsistence diets. Their lecterns set the initial conditions and then they tapped away, looking bored or nervous or impatient or absorbed, using formulas provided by the table, or else supplying some of their own.

It occupied them until lunch, and then all afternoon. Art enjoyed games, and he and Amy always finished well ahead of the others. Their results for a maximum sustainable population ranged from a hundred million (the “immortal tiger” model, as Fort called it) to thirty billion (the “ant farm” model).

“That’s a big range,” Sam noted.

Fort nodded, and eyed them patiently.

“But if you look only at models with the most realistic conditions,” Art said, “you usually get between three and eight billion.”

“And the current population is about twelve billion,” Fort said. “So, say we’re overshot. Now what do we do about that? We’ve got companies to run, after all. Business isn’t going to stop because there’s too many people. Full-world economics isn’t the end of economics, it’s just the end of business as usual. I want Praxis to be ahead of the curve on this. So. It’s low tide, and I’m going back out. You’re welcome to join me. Tomorrow we’ll play a game called Overfull.”

With that he left the room, and they were on their own. They went back to their rooms, and then, as it was close to dinnertime, to the dining hall. Fort was not there, but several of his elderly associates from the night before were; and joining them tonight was a crowd of young men and women, all of them lean, bright-faced, healthy-looking. They looked like a track club or a swim team, and more than half were women. Sam’s and Max’s eyebrows shot up and down in a simple Morse code, spelling “Ah ha! Ah ha!” The young men and women ignored that and served them dinner, then returned to the kitchen. Art ate quickly, wondering if Sam and Max were correct in their suppositions. Then he took his plate into the kitchen and started to help at the dishwasher, and said to one of the young women, “What brings you here?”

“It’s a kind of scholarship program,” she said. Her name was Joyce. “We’re all apprentices who joined Praxis last year, and we were selected to come here for classes.”

“Were you by chance working on full-world economics today?”

“No, volleyball.”

Art went back outside, wishing he had gotten selected to their program rather than his. He wondered if there was some big hot-tub facility, down there overlooking the ocean. It did not seem impossible; the ocean here was cool, and if everything was economics, it could be seen as an investment. Maintaining the human infrastructure, so to speak.

Back in the residence, his fellow guests were talking the day over. “I hate this kind of stuff,” said Sam.

“We’re stuck with it,” Max said gloomily. “It’s join a cult or lose your job.”

The others were not so pessimistic. “Maybe he’s just lonely,” Amy suggested.

Sam and Max rolled their eyes and glanced toward the kitchen.

“Maybe he always wanted to be a teacher,” Sally said.

“Maybe he wants to keep Praxis growing ten percent per year,” George said, “full world or not.”

Sam and Max nodded at this, and Elizabeth looked annoyed. “Maybe he wants to save the world!” she said.

“Right,” Sam said, and Max and George snickered.

“Maybe he’s got this room bugged,” Art said, which cut short the conversation like a guillotine.

• • •

The days that followed were much like the first one. They sat in the conference room, and Fort circled them and talked through the mornings, sometimes coherently, sometimes not. One morning he spent three hours talking about feudalism— how it was the clearest political expression of primate dominance dynamics, how it had never really gone away, how transnational capitalism was feudalism writ large, how the aristocracy of the world had to figure out how to subsume capitalist growth within the steady-state stability of the feudal model. Another morning he talked about a caloric theory of value called eco-economics, apparently first worked out by early settlers on Mars; Sam and Max rolled their eyes at that news, while Fort droned on about Taneev and Tokareva equations, scribbling illegibly on a drawing board in the corner.

But this pattern didn’t last, because a few days after their arrival a big swell came in from the south, and Fort canceled their meetings and spent all his time surfing or skimming over the waves in a birdsuit, which was a light broad-winged bodysuit, a flexible fly-by-wire hang glider that translated the flyer’s muscle movements into the proper semi-rigid configurations for successful flight. Most of the young scholarship winners joined him in the air, swooping around like Icaruses, and then dropping in and planing swiftly over the cushions of air pushed up by every breaking wave, air surfing just like the pelicans that had invented the sport.

Art went out and thrashed around on a body board, enjoying the water, which was chill, but not so much as to absolutely require a wetsuit. He hung out near the break that Joyce surfed, and chatted with her between sets, and found out that the other ancient kitchen workers were good friends of Fort’s, veterans of the first years of Praxis’s rise to prominence. The young scholars referred to them as the Eighteen Immortals. Some of the Eighteen were based at the camp, while others dropped by for a kind of ongoing reunion, conferring about problems, advising the current Praxis leadership on policy, running seminars and classes, and playing in the waves. Those who didn’t care for the water worked in the gardens.

Art inspected the gardeners closely as he hiked back up to the compound. They worked in something resembling slow motion, talking to each other all the while. Currently the main task appeared to be harvesting the tortured apple bushes.

The south swell subsided, and Fort reconvened Art’s group. One day the topic was Full-World Business Opportunities, and Art began to see why he and his six fellows might have been chosen to attend: Amy and George worked in contraception, Sam and Max in industrial design, Sally and Elizabeth in agricultural technology, and he himself in resource recovery. They all worked in full-world businesses already, and in the afternoon’s games they proved fairly good at designing new ones.

Another day Fort proposed a game in which they solved the full-world problem by returning to an empty world. They were to suppose the release of a plague vector that would kill everyone in the world who had not had the gerontological treatment. What would the pros and cons of such an action be?

The group stared at their lecterns, nonplussed. Elizabeth declared that she wouldn’t play a game based on such a monstrous idea.

“It is a monstrous idea,” Fort agreed. “But that doesn’t make it impossible. I hear things, you see. Conversations at certain levels. Among the leadership of the big transnationals, for instance, there are discussions. Arguments. You hear all kinds of ideas put out quite seriously, including some like this one. Everyone deplores them and the subject changes. But no one claims that they are technically impossible. And some seem to think that they would solve certain problems that otherwise are unsolvable.”

The group considered this thought unhappily. Art suggested that agricultural workers would be in short supply.

Fort was looking out at the ocean. “That’s the fundamental problem with a collapse,” he said thoughtfully. “Once you start one, it’s hard to pick a point at which one can confidently say it will stop. Let’s go on.”

And they did, rather subdued. They played Population Reduction, and given the alternative they had just contemplated, went at it with a certain intensity. Each of them took a turn being Emperor of the World, as Fort put it, and outlined his or her plan in some detail.

When it was Art’s turn, he said, “I would give everyone alive a birthright which entitled them to parent three-quarters of a child.”

Everyone laughed, including Fort. But Art persevered. He explained that every pair of parents would thus have the right to bear a child and a half; after having one, they could either sell the right to the other half, or arrange to buy a half from some other couple and go on to have a second child. Prices for half children would fluctuate in classic supply/demand fashion. Social consequences would be positive; people who wanted extra children would have to sacrifice for them, and those who didn’t would have a source of income to help support the one they had. When populations dropped far enough, the World Emperor might consider changing the birthright to one child per person, which would be close to a demographic steady state; but given the longevity treatment, the three-quarters limit might have to be in effect for a long time.

When Art was done outlining the proposal he looked up from the notes on his lectern. Everyone was staring at him.

“Three quarters of a child,” Fort repeated with a grin, and everyone laughed again. “I like that.” The laughter stopped. “It would finally establish a monetary value for a human life, on the open market. So far the work done in that area has been sloppy at best. Lifetime incomes and expenditures and the like.” He sighed and shook his head. “The truth is, economists cook most of the numbers in the back room. Value isn’t really an economic calculation. No, I like this. Let’s see if we can estimate how much the price of a half child would be. I’m sure there would be speculation, middlemen, a whole market apparatus.”

So they played the three-quarters game for the rest of the afternoon, getting right down to the commodities market and the plots for soap operas. When they finished, Fort invited them to a barbecue on the beach.

• • •

They went back to their rooms and put on windbreakers, and hiked down the valley path into the glare of the sunset. On the beach under a dune was a big bonfire, being tended by some of the young scholars. As they approached and sat on blankets around the fire, a dozen or so of the Eighteen Immortals landed out of the air, running across the sand and bringing their wings slowly down, then unzipping from their suits, and pulling wet hair out of their eyes, and talking among themselves about the wind. They helped each other out of the long wings, and stood in their bathing suits goose-pimpled and shivering: centenarian flyers with wiry arms outstretched to the fire, the women just as muscular as the men, their faces just as lined by a million years of squinting into the sun and laughing around the fire. Art watched the way Fort joked with his old friends, the easy way they toweled each other down. Secret lives of the rich and famous! They ate hot dogs and drank beer. The flyers went behind a dune and returned dressed in pants and sweatshirts, happy to stand by the fire a bit longer, combing out each other’s wet hair. It was a dusky twilight, and the evening onshore breeze was salty and cold. The big mass of orange flame danced in the wind, and light and shadow flickered over Fort’s simian visage. As Sam had said earlier, he didn’t look a day over eighty.

Now he sat among his seven guests, who were sticking together, and stared into the coals and started talking again. The people on the other side of the fire continued in their conversations, but Fort’s guests leaned closer to hear him over the wind and waves and crackling wood, looking a bit lost without their lecterns in their laps.

“You can’t make people do things,” Fort said. “It’s a matter of changing ourselves. Then people can see, and choose. In ecology they have what they call the founder principle. An island population is started by a small number of settlers, so it has only a small fraction of the genes of the parent population. That’s the first step toward speciation. Now I think we need a new species, economically speaking of course. And Praxis itself is the island. The way we structure it is a kind of engineering of the genes we came to it with. We have no obligation to abide by the rules as they stand now. We can make a new species. Not feudal. We’ve got the collective ownership and decision-making, the policy of constructive action. We’re working toward a corporate state similar to the civic state they’ve made in Bologna. That’s a kind of democratic communist island, outperforming the capitalism around it, and constructing a better way to live. Do you think that kind of democracy is possible? We’ll have to try playing at that one of these afternoons.”

“Whatever you say,” Sam remarked, which got him a sharp glance from Fort.

• • •

The following morning it was sunny and warm, and Fort decided the weather was too good to stay indoors. So they returned to the beach and set up under a big awning near the firepit, among coolers and hammocks strung between the awning poles. The ocean was a deep bright blue, the waves small but crisp, and often occupied by wetsuited surfers. Fort sat in one of the hammocks and lectured on selfishness and altruism, taking his examples from economics, sociobiology, and bioethics. He concluded that strictly speaking, there was no such thing as altruism. It was only selfishness taking the long view, acknowledging the real costs of behavior and making sure to pay them in order not to run up any long-term debts. A very sound economic practice, in fact, if properly directed and applied. As he tried to prove by means of the selfish-altruism games they then played, like Prisoner’s Dilemma, or Tragedy of the Commons.

The next day they met in the surf camp again, and after a meandering talk on voluntary simplicity, they played a game Fort called Marcus Aurelius. Art enjoyed this game as he did all the others, and he played it well. But each day his lectern notes were getting shorter; for this day they read, in their entirety, Consumption— appetite— artificial needs— real needs— real costs— straw beds! Env. Impact = population x appetite x efficiency— in tropics refrigerators not a luxury— community refrigerators— cold houses— Sir Thomas More.

That evening the conferees ate alone, and their discussion over dinner was tired. “I suppose this place is a kind of voluntary simplicity,” Art remarked.

“Would that include the young scholars?” Max asked.

“I don’t see the Immortals doing very much with them.”

“They just like to look,” Sam said. “When you’re that old . . .”

“I wonder how long he plans to keep us here,” Max said. “We’ve only been here a week and it’s already boring.”

“I kind of like it,” Elizabeth said. “It’s relaxing.”

Art found that he agreed with her. He was getting up early; one of the scholars marked every dawn by striking a wooden block with a big wooden mallet, in a descending interval that drew Art out of sleep every time: tock . . . . . . tock . . . . . . tock . . . . . . tock . . . tock . . tock, tock tock toc-toc- toc-toc-to-to-to-t-t-ttttttt. After that Art went out into gray wet mornings, full of birdcalls. The sound of the waves was always there, as if invisible shells were held to his ears. When he walked the trail through the farm he always found some of the Eighteen Immortals around, chatting as they worked with hoes or pruning shears, or sat under the big oak tree looking out at the ocean. Fort was often among them. Art could hike through the hour before breakfast with the knowledge that he would spend the rest of the day in a warm room or on a warm beach, talking and playing games. Was that simple? He wasn’t sure. It was definitely relaxing; he had never spent time like it.

But of course there was more to it than that. It was, as Sam and Max kept reminding them, a kind of test. They were being judged. The old man was watching them, and maybe the Eighteen Immortals as well, and the young scholars too, the “apprentices” who began to look to Art like serious powers, young hotshots who ran a lot of the day-to-day operations of the compound, and perhaps of Praxis too, even at its highest levels— in consultation with the Eighteen, or perhaps not. After listening to Fort ramble, he could see how one might be inclined to bypass him when it came to practical matters. And the conversations around the dishwasher sometimes had the tone of siblings squabbling over how to deal with incapacitated parents. . . .

Anyway, a test: one night Art went over to the kitchen to get a glass of milk before bed, and passed a small room off the dining hall, where a number of people, old and young, were watching a videotape of the morning’s session with Fort. Art went back to his room, deep in thought.

The next morning in the conference room Fort circled the room in his usual way. “The new opportunities for growth are no longer in growth.”

Sam and Max glanced at each other ever so briefly.

“That’s what all this full-world thinking comes down to. So we’ve got to identify the new nongrowth growth markets, and get into them. Now recall that natural capital can be divided into marketable and nonmarketable. Nonmarketable natural capital is the substrate from which all marketable capital arises. Given its scarcity and the benefits that it provides, it would make sense according to standard supply/demand theory to set its price as infinite. I’m interested in anything that has a theoretically infinite price. It’s an obvious investment. Essentially it’s infrastructure investment, but at the most basic biophysical level. Infra-infrastructure, so to speak, or bioinfrastructure. And that’s what I want Praxis to start doing. We obtain and rebuild whatever bioinfrastructure has been depleted by liquidation. It’s long-term investment, but the yields will be fantastic.”

“Isn’t most bioinfrastructure publicly owned?” Art asked.

“Yes. Which means close cooperation with the governments involved. Praxis’s gross annual product is much larger than most countries’. What we need to do is find countries with small GNPs and bad CFIs.”

“CFI?” Art said.

“Country Future Index. It’s an alternative to the GNP measurement, taking into account debt, political stability, environmental health and the like. A useful cross-check on the GNP, and it helps tag countries that could use our help. We identify those, go to them and offer them a massive capital investment, plus political advice, security, whatever they need. In return we take custody of their bioinfrastructure. We also have access to their labor. It’s an obvious partnership. I think it will be the coming thing.”

“How do we fit in?” Sam asked, gesturing at the group.Diplomatic work! Art wrote in his lectern.

Fort looked at them one by one. “I’m going to give each of you a different assignment. I’ll want you to keep them confidential. You’ll be leaving here separately in any case, and going different places. You’ll all be doing diplomatic work as a Praxis liaison, as well as specific jobs involved with bioinfrastructure investment. I’ll give you the details in private. Now let’s take an early lunch, and afterward I’ll meet with you one at a time.”

He spent the afternoon wandering around the gardens, looking at the espaliered apple bushes. Apparently he was not early in the list of personal appointments with Fort. He shrugged at that. It was a cloudy day, and the flowers in the garden were wet and vibrant. It would be tough to move back to his studio under the freeway in San Jose. He wondered what Sharon was doing, whether she ever thought of him. Sailing with her vice-chairman, no doubt.

It was nearly sunset, and he was about to go back to his room and get ready for dinner when Fort appeared on the central path. “Ah, there you are,” he said. “Let’s go down to the oak.”

They sat by the big tree’s trunk. The sun was cutting under the low clouds, and everything was turning the color of the roses. “You live in a beautiful place,” Art said.

Fort didn’t appear to hear him. He was looking up at the underlit clouds billowing overhead.

After a few minutes of this contemplation he said, “We want you to acquire Mars.”

“Acquire Mars,” Art repeated.

“Yes. In the sense that I spoke about this morning. These national-transnational partnerships are the coming thing, there’s no doubt about it. The old flag-of-convenience relationships were suggestive, but they need to be taken further, so that we have more control over our investment. We did that with Sri Lanka, and we’ve had so much success in our deal there that the other big transnats are all imitating us, actively recruiting countries in trouble.”

“But Mars isn’t a country.”

“No. But it is in trouble. When the first elevator crashed, its economy was shattered. Now the new elevator is in place, and things are ready to happen. I want Praxis to be ahead of the curve. Of course the other big investors are all still there too, jockeying for position, and that will only intensify now that the new elevator is up.”

“Who runs the elevator?”

“A consortium led by Subarashii.”

“Isn’t that a problem?”

“Well, it gives them an edge. But they don’t understand Mars. They think it’s just a new source of metals. They don’t see the possibilities.”

“The possibilities for . . .”

“For development! Mars isn’t just an empty world, Randolph— in economic terms, it’s nearly a nonexistent world. Its bioinfrastructure has to be constructed, you see. I mean one could just extract the metals and move on, which is what Subarashii and the others seem to have in mind. But that’s treating it like nothing more than a big asteroid. Which is stupid, because its value as a base of operations, as a planet so to speak, far surpasses the value of its metals. All its metals together total about twenty trillion dollars, but the value of a terraformed Mars is more in the neighborhood of two hundred trillion dollars. That’s about one third of the current Gross World Value, and even that doesn’t make proper assessment of its scarcity value, if you ask me. No, Mars is bioinfrastructure investment, just like I was talking about. Exactly the kind of thing Praxis is looking for.”

“But acquisition . . .” Art said. “I mean, what are we talking about?”

“Not what. Who.”

“Who?”

“The underground.”

“The underground!”

Fort gave him time to think it over. Television, the tabloids, and the nets were full of tales of the survivors of 2061, living in underground shelters in the wild southern hemisphere, led by John Boone and Hiroko Ai, tunneling everywhere, in contact with aliens, and dead celebrities, and current world leaders. . . . Art stared at Fort, a bona fide current world leader, shocked by the sudden notion that these Pellucidarian fantasies might have some truth to them. “Does it really exist?”

Fort nodded. “It does. I’m not in full contact with it, you understand, and I don’t know how extensive it is. But I’m sure that some of the First Hundred are still alive. You know the Taneev-Tokareva theories I talked about when you first arrived? Well, those two, and Ursula Kohl, and that whole biomedical team, they all lived in the Acheron Fin, north of Olympus Mons. During the war the facility was destroyed. But there were no bodies at the site. So about six years ago I had a Praxis team go in and rebuild the facility. When it was done we named it the Acheron Institute, and we left it empty. Everything is on-line and ready to go, but nothing is happening there, except for a small annual conference on their eco-economics. And last year, when the conference was over, one of the cleanup crew found a few pages in a fax tray. Comments on one of the papers presented. No signature, no source. But there was some work there that I’m positive was written by Taneev or Tokareva, or someone very familiar with their work. And I think it was a little hello.”

A very little hello, Art thought. But Fort seemed to read his mind: “I’ve just gotten an even bigger hello. I don’t know who it is. They’re being very cautious. But they’re out there.”

Art swallowed. It was big news, if true. “And so you want me to . . .”

“I want you to go to Mars. We have a project there that will be your cover story, salvaging a section of the fallen elevator cable. But while you’re doing that, I’ll be making arrangements to get you together with this person who has contacted me. You won’t have to initiate anything. They’ll make the move, and take you in. But look. In the beginning, I don’t want you to let them know exactly what you’re trying to do. I want you to go to work on them. Find out who they are, and how extensive their operation is, and what they want. And how we might deal with them.”

“So I’ll be a kind of—”

“A kind of diplomat.”

“A kind of spy, I was going to say.”

Fort shrugged. “It depends on who you’re with. This project has to remain a secret. I deal with a lot of the other transnat leaders, and they’re scared people. Perceived threats to the current order often get attacked quite brutally. And some of them already think Praxis is a threat. So for the time being there is a hidden arm to Praxis, and this Mars investigation has to be part of that. So if you join, you join the hidden Praxis. Think you can do it?”

“I don’t know.”

Fort laughed. “That’s why I chose you for this mission, Randolph. You seem simple.”

I am simple, Art almost said, and bit his tongue. Instead he said, “Why me?”

Fort regarded him. “When we acquire a new company, we review its personnel. I read your record. I thought you might have the makings of a diplomat.”

“Or a spy.”

“They are often different aspects of the same job.”

Art frowned. “Did you bug my apartment? My old apartment?”

“No.” Fort laughed again. “We don’t do that. People’s records are enough.”

Art recalled the late-night viewing of one of their sessions.

“That and a session down here,” Fort added. “To get to know you.”

Art considered it. None of the Eighteen wanted this job. Nor the scholars, perhaps. Of course it was off to Mars, and then into some invisible world no one knew anything about, maybe for good. Some people might not find it attractive. But for someone at loose ends, maybe looking for new employment, maybe with a potential for diplomacy. . . .

So all this had indeed proved to be a kind of interview process. For a job he hadn’t even known existed. Mars Acquirer. Mars Acquisition Chief. Mars Mole. A Spy in the House of Ares. Ambassador to the Mars Underground. Ambassador to Mars. My oh my, he thought.

“So what do you say?”

“I’ll do it,” Art said.
