Yes, that's her. She's mine.

That final "gift exchange" was the last we ever saw of the heptapods. All at once, all over the world, their looking gla.s.ses became transparent and their ships left orbit. Subsequent a.n.a.lysis of the looking gla.s.ses revealed them to be nothing more than sheets of fused silica, completely inert. The information from the final exchange session described a new cla.s.s of super-conducting materials, but it later proved to duplicate the results of research just completed in j.a.pan: nothing that humans didn't already know.

We never did learn why the heptapods left, any more than we learned what brought them here, or why they acted the way they did. My own new awareness didn't provide that type of knowledge; the heptapods' behavior was presumably explicable from a sequential point of view, but we never found that explanation.

I would have liked to experience more of the heptapods' worldview, to feel the way they feel. Then, perhaps I could immerse myself fully in the necessity of events, as they must, instead of merely wading in its surf for the rest of my life. But that will never come to pa.s.s. I will continue to practice the heptapod languages, as will the other linguists on the looking gla.s.s teams, but none of us will ever progress any further than we did when the heptapods were here.

Working with the heptapods changed my life. I met your father and learned Heptapod B, both of which make it possible for me to know you now, here on the patio in the moonlight. Eventually, many years from now, I'll be without your father, and without you. All I will have left from this moment is the heptapod language. So I pay close attention, and note every detail.

From the beginning I knew my destination, and I chose my route accordingly. But am I working toward an extreme of joy, or of pain? Will I achieve a minimum, or a maximum?

These questions are in my mind when your father asks me, "Do you want to make a baby?" And I smile and answer, "Yes," and I unwrap his arms from around me, and we hold hands as we walk inside to make love, to make you.

Seventy-Two Letters When he was a child, Robert's favorite toy was a simple one, a clay doll that could do nothing but walk forward. While his parents entertained their guests in the garden outside, discussing Victoria's ascension to the throne or the Chartist reforms, Robert would follow the doll as it marched down the corridors of the family home, turning it around corners or back where it came from. The doll didn't obey commands or exhibit any sense at all; if it met a wall, the diminutive clay figure would keep marching until it gradually mashed its arms and legs into misshapen flippers. Sometimes Robert would let it do that, strictly for his own amus.e.m.e.nt. Once the doll's limbs were thoroughly distorted, he'd pick the toy up and pull the name out, stopping its motion in midstride. Then he'd knead the body back into a smooth lump, flatten it out into a plank, and cut out a different figure: a body with one leg crooked, or longer than the other. He would stick the name back into it, and the doll would promptly topple over and push itself around in a little circle.

It wasn't the sculpting that Robert enjoyed; it was mapping out the limits of the name. He liked to see how much variation he could impart to the body before the name could no longer animate it. To save time with the sculpting, he rarely added decorative details; he refined the bodies only as was needed to test the name.

Another of his dolls walked on four legs. The body was a nice one, a finely detailed porcelain horse, but Robert was more interested in experimenting with its name. This name obeyed commands to start and stop and knew enough to avoid obstacles, and Robert tried inserting it into bodies of his own making. But this name had more exacting body requirements, and he was never able to form a clay body it could animate. He formed the legs separately and then attached them to the body, but he wasn't able to erase the seams fully; the name didn't recognize the body as a single continuous piece.

He scrutinized the names themselves, looking for some simple subst.i.tutions that might distinguish two-leggedness from four-leggedness, or make the body obey simple commands. But the names looked entirely different; on each sc.r.a.p of parchment were inscribed seventy-two tiny Hebrew letters, arranged in twelve rows of six, and so far as he could tell, the order of the letters was utterly random.

Robert Stratton and his fourth-form cla.s.smates sat quietly as Master Trevelyan paced between the rows of desks.

"Langdale, what is the doctrine of names?"

"All things are reflections of G.o.d, and, um, all-"

"Spare us your b.u.mbling. Thorburn, can you you tell us the doctrine of names?" tell us the doctrine of names?"

"As all things are reflections of G.o.d, so are all names reflections of the divine name."

"And what is an object's true name?"

"That name which reflects the divine name in the same manner as the object reflects G.o.d."

"And what is the action of a true name?"

"To endow its object with a reflection of divine power."

"Correct. Halliwell, what is the doctrine of signatures?"

The natural philosophy lesson continued until noon, but because it was a Sat.u.r.day, there was no instruction for the rest of the day. Master Trevelyan dismissed the cla.s.s, and the boys of Cheltenham school dispersed.

After stopping at the dormitory, Robert met his friend Lionel at the border of school grounds. "So the wait's over? Today's the day?" Robert asked.

"I said it was, didn't I?"

"Let's go, then." The pair set off to walk the mile and a half to Lionel's home.

During his first year at Cheltenham, Robert had known Lionel hardly at all; Lionel was one of the day boys, and Robert, like all the boarders, regarded them with suspicion. Then, purely by chance, Robert ran into him while on holiday, during a visit to the British Museum. Robert loved the museum: the frail mummies and immense sarcophagi; the stuffed platypus and pickled mermaid; the wall bristling with elephant tusks and moose antlers and unicorn horns. That particular day he was at the display of elemental sprites: he was reading the card explaining the salamander's absence when he suddenly recognized Lionel, standing right next to him, peering at the undine in its jar. Conversation revealed their shared interest in the sciences, and the two became fast friends.

As they walked down the road, they kicked a large pebble back and forth between them. Lionel gave the pebble a kick, and laughed as it skittered between Robert's ankles. "I couldn't wait to get out of there," he said. "I think one more doctrine would have been more than I could bear."

"Why do they even bother calling it natural philosophy?" said Robert. "Just admit it's another theology lesson and be done with it." The two of them had recently purchased A Boy's Guide to Nomenclature A Boy's Guide to Nomenclature, which informed them that nomenclators no longer spoke in terms of G.o.d or the divine name. Instead, current thinking held that there was a lexical universe as well as a physical one, and bringing an object together with a compatible name caused the latent potentialities of both to be realized. Nor was there a single "true name" for a given object: depending on its precise shape, a body might be compatible with several names, known as its "euonyms," and conversely a simple name might tolerate significant variations in body shape, as his childhood marching doll had demonstrated.

When they reached Lionel's home, they promised the cook they would be in for dinner shortly and headed to the garden out back. Lionel had converted a toolshed in his family's garden into a laboratory, which he used to conduct experiments. Normally Robert came by on a regular basis, but recently Lionel had been working on an experiment that he was keeping secret. Only now was he ready to show Robert his results. Lionel had Robert wait outside while he entered first, and then let him enter.

A long shelf ran along every wall of the shed, crowded with racks of vials, stoppered bottles of green gla.s.s, and a.s.sorted rocks and mineral specimens. A table decorated with stains and scorch marks dominated the cramped s.p.a.ce, and it supported the apparatus for Lionel's latest experiment: a cucurbit clamped in a stand so that its bottom rested in a basin full of water, which in turn sat on a tripod above a lit oil lamp. A mercury thermometer was also fixed in the basin.

"Take a look," said Lionel.

Robert leaned over to inspect the cucurbit's contents. At first it appeared to be nothing more than foam, a dollop of suds that might have dripped off a pint of stout. But as he looked closer, he realized that what he thought were bubbles were actually the interstices of a glistening latticework. The froth consisted of homunculi homunculi: tiny seminal foetuses. Their bodies were transparent individually, but collectively their bulbous heads and strandlike limbs adhered to form a pale, dense foam.

"So you w.a.n.ked off into a jar and kept the s.p.u.n.k warm?" he asked, and Lionel shoved him. Robert laughed and raised his hands in a placating gesture. "No, honestly, it's a wonder. How'd you do it?"

Mollified, Lionel said, "It's a real balancing act. You have to keep the temperature just right, of course, but if you want them to grow, you also have to keep just the right mix of nutrients. Too thin a mix, and they starve. Too rich, and they get over lively and start fighting with each other."

"You're having me on."

"It's the truth; look it up if you don't believe me. Battles amongst sperm are what cause monstrosities to be born. If an injured foetus is the one that makes it to the egg, the baby that's born is deformed."

"I thought that was because of a fright the mother had when she was carrying." Robert could just make out the minuscule squirmings of the individual foetuses. He realized that the froth was ever so slowly roiling as a result of their collective motions.

"That's only for some kinds, like ones that are all hairy or covered in blotches. Babies that don't have arms or legs, or have misshapen ones, they're the ones that got caught in a fight back when they were sperm. That's why you can't provide too rich a broth, especially if they haven't any place to go: they get in a frenzy. You can lose all of them pretty quick that way."

"How long can you keep them growing?"

"Probably not much longer," said Lionel. "It's hard to keep them alive if they haven't reached an egg. I read about one in France that was grown till it was the size of a fist, and they had the best equipment available. I just wanted to see if I could do it at all."

Robert stared at the foam, remembering the doctrine of preformation that Master Trevelyan had drilled into them: all living things had been created at the same time, long ago, and births today were merely enlargements of the previously imperceptible. Although they appeared newly created, these homunculi homunculi were countless years old; for all of human history they had lain nested within generations of their ancestors, waiting for their turn to be born. were countless years old; for all of human history they had lain nested within generations of their ancestors, waiting for their turn to be born.

In fact, it wasn't just them who had waited; he himself must have done the same thing prior to his birth. If his father were to do this experiment, the tiny figures Robert saw would be his unborn brothers and sisters. He knew they were insensible until reaching an egg, but he wondered what thoughts they'd have if they weren't. He imagined the sensation of his body, every bone and organ soft and clear as gelatin, sticking to those of myriad identical siblings. What would it be like, looking through transparent eyelids, realizing the mountain in the distance was actually a person, recognizing it as his brother? What if he knew he'd become as ma.s.sive and solid as that colossus, if only he could reach an egg? It was no wonder they fought.

Robert Stratton went on to read nomenclature at Cambridge's Trinity College. There he studied kabbalistic texts written centuries before, when nomenclators were still called ba'alei shem ba'alei shem and automata were called and automata were called golem golem, texts that laid the foundation for the science of names: the Sefer Yezirah Sefer Yezirah, Eleazar of Worms' Sodei Razayya Sodei Razayya, Abulafia's Hayyei ha-Olam ha-Ba Hayyei ha-Olam ha-Ba. Then he studied the alchemical treatises that placed the techniques of alphabetic manipulation in a broader philosophical and mathematical context: Llull's Ars Magna Ars Magna, Agrippa's De Occulta Philosophia De Occulta Philosophia, Dee's Monas Hieroglyphica Monas Hieroglyphica.

He learned that every name was a combination of several epithets, each designating a specific trait or capability. Epithets were generated by compiling all the words that described the desired trait: cognates and etymons, from languages both living and extinct. By selectively subst.i.tuting and permuting letters, one could distill from those words their common essence, which was the epithet for that trait. In certain instances, epithets could be used as the bases for triangulation, allowing one to derive epithets for traits undescribed in any language. The entire process relied on intuition as much as formulae; the ability to choose the best letter permutations was an unteachable skill.

He studied the modern techniques of nominal integration and factorization, the former being the means by which a set of epithets- pithy and evocative- were commingled into the seemingly random string of letters that made up a name, the latter by which a name was decomposed into its const.i.tuent epithets. Not every method of integration had a matching factorization technique: a powerful name might be refactored to yield a set of epithets different from those used to generate it, and those epithets were often useful for that reason. Some names resisted refactorization, and nomenclators strove to develop new techniques to penetrate their secrets.

Nomenclature was undergoing something of a revolution during this time. There had long been two cla.s.ses of names: those for animating a body, and those functioning as amulets. Health amulets were worn as protection from injury or illness, while others rendered a house resistant to fire or a ship less likely to founder at sea. Of late, however, the distinction between these categories of names was becoming blurred, with exciting results.

The nascent science of thermodynamics, which established the interconvertibility of heat and work, had recently explained how automata gained their motive power by absorbing heat from their surroundings. Using this improved understanding of heat, a Namenmeister Namenmeister in Berlin had developed a new cla.s.s of amulet that caused a body to absorb heat from one location and release it in another. Refrigeration employing such amulets was simpler and more efficient than that based on the evaporation of a volatile fluid, and had immense commercial application. Amulets were likewise facilitating the improvement of automata: an Edinburgh nomenclator's research into the amulets that prevented objects from becoming lost had led him to patent a household automaton able to return objects to their proper places. in Berlin had developed a new cla.s.s of amulet that caused a body to absorb heat from one location and release it in another.

Upon graduation, Stratton took up residence in London and secured a position as a nomenclator at Coade Manufactory, one of the leading makers of automata in England.

Stratton's most recent automaton, cast from plaster of Paris, followed a few paces behind him as he entered the factory building. It was an immense brick structure with skylights for its roof; half of the building was devoted to casting metal, the other half to ceramics. In either section, a meandering path connected the various rooms, each one housing the next step in transforming raw materials into finished automata. Stratton and his automaton entered the ceramics portion.

They walked past a row of low vats in which the clay was mixed. Different vats contained different grades of clay, ranging from common red clay to fine white kaolin, resembling enormous mugs abrim with liquid chocolate or heavy cream; only the strong mineral smell broke the illusion. The paddles stirring the clay were connected by gears to a drive shaft, mounted just beneath the skylights, that ran the length of the room. At the end of the room stood an automatous engine: a cast-iron giant that cranked the drive wheel tirelessly. Walking past, Stratton could detect a faint coolness in the air as the engine drew heat from its surroundings.

The next room held the molds for casting. Chalky white sh.e.l.ls bearing the inverted contours of various automata were stacked along the walls. In the central portion of the room, ap.r.o.n-clad journeymen sculptors worked singly and in pairs, tending the coc.o.o.ns from which automata were hatched.

The sculptor nearest him was a.s.sembling the mold for a putter, a broad-headed quadruped employed in the mines for pushing trolleys of ore. The young man looked up from his work. "Were you looking for someone, sir?" he asked.

"I'm to meet Master Willoughby here," replied Stratton.

"Pardon, I didn't realize. I'm sure he'll be here shortly." The journeyman returned to his task. Harold Willoughby was a Master Sculptor First-Degree; Stratton was consulting him on the design of a reusable mold for casting his automaton. While he waited, Stratton strolled idly amongst the molds. His automaton stood motionless, ready for its next command.

Willoughby entered from the door to the metalworks, his face flushed from the heat of the foundry. "My apologies for being late, Mr. Stratton," he said. "We've been working toward a large bronze for some weeks now, and today was the pour. You don't want to leave the lads alone at a time like that."

"I understand completely," replied Stratton.

Wasting no time, Willoughby strode over to the new automaton. "Is this what you've had Moore doing all these months?" Moore was the journeyman a.s.sisting Stratton on his project.

Stratton nodded. "The boy does good work." Following Stratton's requests, Moore had fashioned countless bodies, all variations on a single basic theme, by applying modeling clay to an armature, and then used them to create plaster casts on which Stratton could test his names.

Willoughby inspected the body. "Some nice detail; looks straightforward enough- hold on now." He pointed to the automaton's hands: rather than the traditional paddle or mitten design, with fingers suggested by grooves in the surface, these were fully formed, each one having a thumb and four distinct and separate fingers. "You don't mean to tell me those are functional?"

"That's correct."

Willoughby's skepticism was plain. "Show me."

Stratton addressed the automaton. "Flex your fingers." The automaton extended both hands, flexed and straightened each pair of fingers in turn, and then returned its arms to its sides.

"I congratulate you, Mr. Stratton," said the sculptor. He squatted to examine the automaton's fingers more closely. "The fingers need to be bent at each joint for the name to take?"

"That's right. Can you design a piece mold for such a form?"

Willoughby clicked his tongue several times. "That'll be a tricky bit of business," he said. "We might have to use a waste mold for each casting. Even with a piece mold, these'd be very expensive for ceramic."

"I think they will be worth the expense. Permit me to demonstrate." Stratton addressed the automaton. "Cast a body; use that mold over there."

The automaton trudged over to a nearby wall and picked up the pieces of the mold Stratton had indicated: it was the mold for a small porcelain messenger. Several journeymen stopped what they were doing to watch the automaton carry the pieces over to a work area. There it fitted the various sections together and bound them tightly with twine. The sculptors' wonderment was apparent as they watched the automaton's fingers work, looping and threading the loose ends of the twine into a knot. Then the automaton stood the a.s.sembled mold upright and headed off to get a pitcher of clay slip.

"That's enough," said Willoughby. The automaton stopped its work and resumed its original standing posture. Examining the mold, Willoughby asked, "Did you train it yourself?"

"I did. I hope to have Moore train it in metal casting."

"Do you have names that can learn other tasks?"

"Not as yet. However, there's every reason to believe that an entire cla.s.s of similar names exists, one for every sort of skill needing manual dexterity."

"Indeed?" Willoughby noticed the other sculptors watching, and called out, "If you've nothing to do, there's plenty I can a.s.sign to you." The journeymen promptly resumed their work, and Willoughby turned back to Stratton. "Let us go to your office to speak about this further."

"Very well." Stratton had the automaton follow the two of them back to the frontmost of the complex of connected buildings that was Coade Manufactory. They first entered Stratton's studio, which was situated behind his office proper. Once inside, Stratton addressed the sculptor. "Do you have an objection to my automaton?"

Willoughby looked over a pair of clay hands mounted on a worktable. On the wall behind the table were pinned a series of schematic drawings showing hands in a variety of positions. "You've done an admirable job of emulating the human hand. I am concerned, however, that the first skill in which you trained your new automaton is sculpture."

"If you're worried that I am trying to replace sculptors, you needn't be. That is absolutely not my goal."

"I'm relieved to hear it," said Willoughby. "Why did you choose sculpture, then?"

"It is the first step of a rather indirect path. My ultimate goal is to allow automatous engines to be manufactured inexpensively enough so that most families could purchase one."

Willoughby's confusion was apparent. "How, pray tell, would a family make use of an engine?"

"To drive a powered loom, for example."

"What are you going on about?"

"Have you ever seen children who are employed at a textile mill? They are worked to exhaustion; their lungs are clogged with cotton dust; they are so sickly that you can hardly conceive of their reaching adulthood. Cheap cloth is bought at the price of our workers' health; weavers were far better off when textile production was a cottage industry."

"Powered looms were what took weavers out of cottages. How could they put them back in?"

Stratton had not spoken of this before, and welcomed the opportunity to explain. "The cost of automatous engines has always been high, and so we have mills in which scores of looms are driven by an immense coal-heated Goliath. But an automaton like mine could cast engines very cheaply. If a small automatous engine, suitable for driving a few machines, becomes affordable to a weaver and his family, then they can produce cloth from their home as they did once before. People could earn a decent income without being subjected to the conditions of the factory."

"You forget the cost of the loom itself," said Willoughby gently, as if humoring him. "Powered looms are considerably more expensive than the hand looms of old."

"My automata could also a.s.sist in the production of cast-iron parts, which would reduce the price of powered looms and other machines. This is no panacea, I know, but I am nonetheless convinced that inexpensive engines offer the chance of a better life for the individual craftsman."

"Your desire for reform does you credit. Let me suggest, however, that there are simpler cures for the social ills you cite: a reduction in working hours, or the improvement of conditions. You do not need to disrupt our entire system of manufacturing."

"I think what I propose is more accurately described as a restoration than a disruption."

Now Willoughby became exasperated. "This talk of returning to a family economy is all well and good, but what would happen to sculptors? Your intentions notwithstanding, these automata of yours would put sculptors out of work. These are men who have undergone years of apprenticeship and training. How would they feed their families?"

Stratton was unprepared for the sharpness in his tone. "You overestimate my skills as a nomenclator," he said, trying to make light. The sculptor remained dour. He continued. "The learning capabilities of these automata are extremely limited. They can manipulate molds, but they could never design them; the real craft of sculpture can be performed only by sculptors. Before our meeting, you had just finished directing several journeymen in the pouring of a large bronze; automata could never work together in such a coordinated fashion. They will perform only rote tasks."

"What kind of sculptors would we produce if they spend their apprenticeship watching automata do their jobs for them? I will not have a venerable profession reduced to a performance by marionettes."

"That is not what would happen," said Stratton, becoming exasperated himself now. "But examine what you yourself are saying: the status that you wish your profession to retain is precisely that which weavers have been made to forfeit. I believe these automata can help restore dignity to other professions, and without great cost to yours."

Willoughby seemed not to hear him. "The very notion that automata would make automata! Not only is the suggestion insulting, it seems ripe for calamity. What of that ballad, the one where the broomsticks carry water buckets and run amuck?"

"You mean 'Der Zauberlehrling'?" said Stratton. "The comparison is absurd. These automata are so far removed from being in a position to reproduce themselves without human partic.i.p.ation that I scarcely know where to begin listing the objections. A dancing bear would sooner perform in the London Ballet."

"If you'd care to develop an automaton that can dance the ballet, I would fully support such an enterprise. However, you cannot continue with these dexterous automata."

"Pardon me, sir, but I am not bound by your decisions."
