“Um-m-m.” Mirabile dictu, Anglesey remained calm. He rubbed his chin with one skeletal hand. “Can you be more explicit?”

  “Only in a rough way,” replied Cornelius. “Your conscious mind sends a motor impulse along the psibeam to Joe. Simultaneously, your subconscious mind, being scared of the whole business, emits the glandular-vascular-cardiac-visceral impulses associated with fear. These react on Joe, whose tension is transmitted back along the beam. Feeling Joe’s somatic fear symptoms, your subconscious gets still more worried, thereby increasing the symptoms. Get it? It’s exactly similar to ordinary neurasthenia, with this exception, that since there is a powerful amplifier, the K tube, involved, the oscillations can build up uncontrollably within a second or two. You should be thankful the tube does burn out—otherwise your brain might do so!”

  For a moment Anglesey was quiet. Then he laughed. It was a hard, barbaric laughter. Cornelius started as it struck his eardrums.

  “Nice idea,” said the esman. “But I’m afraid it won’t fit all the data. You see, I like it down there. I like being Joe.”

  He paused for a while, then continued in a dry impersonal tone; “Don’t judge the environment from my notes. They’re just idiotic things like estimates of wind velocity, temperature variations, mineral properties—insignificant. What I can’t put in is how Jupiter looks through a Jovian’s infrared-seeing eyes.”

  “Different, I should think,” ventured Cornelius after a minute’s clumsy silence.

  “Yes and no. It’s hard to put into language. Some of it I can’t, because man hasn’t got the concepts. But…oh, I can’t describe it. Shakespeare himself couldn’t. Just remember that everything about Jupiter which is cold and poisonous and gloomy to us is right for Joe.”

  Anglesey’s tone grew remote, as if he spoke to himself. “Imagine walking under a glowing violet sky, where great flashing clouds sweep the earth with shadow and rain strides beneath them. Imagine walking on the slopes of a mountain like polished metal, with a clean red flame exploding above you and thunder laughing in the ground. Imagine a cool wild stream, and low trees with dark coppery flowers, and a waterfall—methanefall, whatever you like—leaping off a cliff, and the strong live wind shakes its mane full of rainbows! Imagine a whole forest, dark and breathing, and here and there you glimpse a pale-red wavering will-o’-the-wisp, which is the life radiation of some fleet, shy animal, and…and…”

  Anglesey croaked into silence. He stared down at his clenched fists then he closed his eyes tight and tears ran out between the lids, “Imagine being strong!”

  Suddenly he snatched up the helmet, crammed it on his head and twirled the control knobs. Joe had been sleeping, down in the night, but Joe was about to wake up and—roar under the four great moons till all the forest feared him?

  Cornelius slipped quietly out of the room.

  * * *

  In the long brazen sunset light, beneath dusky cloud banks brooding storm, he strode up the hill slope with a sense of day’s work done. Across his back, two woven baskets balanced each other, one laden with the pungent black fruit of the thorn tree and one with cable-thick creepers to be used as rope. The ax on his shoulder caught the waning sunlight and tossed it blindingly back.

  It had not been hard labor, but weariness dragged at his mind and he did not relish the household chores yet to be performed, cooking and cleaning and all the rest. Why couldn’t they hurry up and get him some helpers?

  His eyes sought the sky resentfully. Moon Five was hidden; down here, at the bottom of the air ocean, you saw nothing but the sun and the four Galilean satellites. He wasn’t even sure where Five was just now, in relation to himself. Wait a minute, it’s sunset here, but if I went out to the viewdome I’d see Jupiter in the last quarter, or would I, oh, hell, it only takes us half an Earth day to swing around the planet anyhow—

  Joe shook his head. After all this time, it was still damnably hard, now and then, to keep his thoughts straight. I, the essential I, am up in heaven, riding Jupiter Five between cold stars. Remember that. Open your eyes, if you will, and see the dead control room superimposed on a living hillside.

  He didn’t, though. Instead, he regarded the boulders strewn windblasted gray over the tough mossy vegetation of the slope. They were not much like Earth rocks, nor was the soil beneath his feet like terrestrial humus.

  For a moment Anglesey speculated on the origin of the silicates, aluminates, and other stony compounds. Theoretically, all such materials should be inaccessibly locked in the Jovian core, down where the pressure got vast enough for atoms to buckle and collapse. Above the core should lie thousands of miles of allotropic ice, and then the metallic-hydrogen layer. There should not be complex minerals this far up, but there were.

  Well, possibly Jupiter had formed according to theory, but had thereafter sucked enough cosmic dust, meteors, gases and vapors down its great throat of gravitation to form a crust several miles thick. Or more likely the theory was altogether wrong. What did they know, what could they know, the soft pale worms of Earth?

  Anglesey stuck his—Joe’s—fingers in his mouth and whistled. A baying sounded in the brush, and two midnight forms leaped toward him. He grinned and stroked their heads; training was progressing faster than he’d hoped, with these pups of the black caterpillar beasts he had taken. They would make guardians for him, herders, servants.

  On the crest of the hill, Joe was building himself a home. He had logged off an acre of ground and erected a stockade. Within the grounds there now stood a lean-to for himself and his stores, a methane well, and the beginnings of a large, comfortable cabin.

  But there was too much work for one being. Even with the half-intelligent caterpillars to help, and with cold storage for meat, most of his time would still go to hunting. The game wouldn’t last forever either; he had to start agriculture within the next year or so—Jupiter year, twelve Earth years, thought Anglesey. There was the cabin to finish and furnish; he wanted to put a waterwheel, no, methanewheel, in the river to turn any of a dozen machines he had in mind, he wanted to experiment with alloyed ice and—

  And, quite apart from his need of help, why should he remain alone, the single thinking creature on an entire planet? He was a male in this body, with male instincts—in the long run, his health was bound to suffer if he remained a hermit, and right now the whole project depended on Joe’s health.

  It wasn’t right!

  But I am not alone. There are fifty men on the satellite with me. I can talk to any of them, anytime I wish. It’s only that I seldom wish it, these days. I would rather be Joe.

  Nevertheless…I, the cripple, feel all the tiredness, anger, hurt, frustration, of that wonderful biological machine called Joe. The others don’t understand. When the ammonia gale flays open his skin. It is I who bleed.

  Joe lay down on the ground, sighing. Fangs flashed in the mouth of the black beast which humped over to lick his face. His belly growled with hunger, but he was too tired to fix a meal. Once he had the dogs trained…

  Another pseudo would be so much more rewarding to educate.

  He could almost see it, in the weary darkening of his brain. Down there, in the valley below the hill, fire and thunder as the ship came to rest. And the steel egg would crack open, the steel arms—already crumbling, puny work of worms!—lift out the shape within and lay it on the earth.

  She would stir, shrieking in her first lungful of air looking about with blank mindless eyes. And Joe would come and carry her home. And he would feed her, care for her, show her how to walk—it wouldn’t take long, an adult body would learn those things very fast. In a few weeks she would even be talking, be an individual, a soul.

  Did you ever think, Edward Anglesey, in the days when you also walked, that your wife would be a gray four-legged monster?

  Never mind that. The important thing was to get others of his kind down here female and male. The station’s niggling little plan would have him wait two more Earth years, and then send him only another dummy like himself, a contemptible human mind looking through eyes which belonged rightfully to a Jovian. It was not to be tolerated.

  If he weren’t so tired…

  Joe sat up. Sleep drained from him as the realization entered. He wasn’t tired, not to speak of. Anglesey was. Anglesey, the human side of him, who for months had slept only in cat naps, whose rest had lately been interrupted by Cornelius—it was the human body which drooped, gave up, and sent wave after soft wave of sleep down the psibeam to Joe.

  Somatic tension traveled skyward; Anglesey jerked awake.

  He swore. As he sat there beneath the helmet, the vividness of Jupiter faded with his scattering concentration, as if it grew transparent; the steel prison which was his laboratory strengthened behind it. He was losing contact. Rapidly, with the skill of experience, he brought himself back into phase with the neural currents of the other brain. He willed sleepiness on Joe, exactly as a man wills it on himself.

  And, like any other insomniac, he failed. The Joe body was too hungry. It got up and walked across the compound toward its shack.

  The K tube went wild and blew itself out.

  * * *

  The night before the ships left, Viken and Cornelius sat up late. It was not truly a night, of course. In twelve hours the tiny moon was hurled clear around Jupiter, from darkness back to darkness, and there might well be a pallid little sun over its crags when the clocks said witches were abroad in Greenwich. But most of the personnel were asleep at this hour.

  Viken scowled. “I don’t like it,” he said. “Too sudden a change of plans. Too big a gamble.”

  “You are only risking—how many?—three male and a dozen female pseudos,” Cornelius replied.

  “And fifteen J ships. All we have. If Anglesey’s notion doesn’t work, it will be months, a year or more, till we can have others built and resume aerial survey.”

  “But if it does work,” said Cornelius, “you won’t need any J ships, except to carry down more pseudos. You will be too busy evaluating data from the surface to piddle around in the upper atmosphere.”

  “Of course. But we never expected it so soon. We were going to bring more esmen out here, to operate some more pseudos—”

  “But they aren’t needed,” said Cornelius. He struck a cigar to life and took a long pull on it, while his mind sought carefully for words. “Not for a while, anyhow. Joe has reached a point where, given help, he can leap several thousand years of history—he may even have a radio of sorts operating in the fairly near future, which would eliminate the necessity of much of your esping. But without help, he’ll just have to mark time. And it’s stupid to make a highly trained human esman perform manual labor, which is all that the other pseudos are needed for at this moment. Once the Jovian settlement is well established, certainly, then you can send down more puppets.”

  “The question is, though,” persisted Viken, “can Anglesey himself educate all those pseudos at once? They’ll be helpless as infants for days. It will be weeks before they really start thinking and acting for themselves. Can Joe take care of them meanwhile?”

  “He has food and fuel stored for months ahead,” said Cornelius. “As for what Joe’s capabilities are—well, hm-m-m, we just have to take Anglesey’s judgment. He has the only inside information.”

  “And once those Jovians do become personalities,” worried Viken, “are they necessarily going to string along with Joe? Don’t forget, the pseudos are not carbon copies of each other. The uncertainty principle assures each one a unique set of genes. If there is only one human mind on Jupiter, among all those aliens—”

  “One human mind?” It was barely audible. Viken opened his mouth inquiringly. The other man hurried on.

  “Oh, I’m sure Anglesey can continue to dominate them,” said Cornelius. “His own personality is rather—tremendous.”

  Viken looked startled. “You really think so?”

  The psionicist nodded. “Yes. I’ve seen more of him in the past weeks than anyone else. And my profession naturally orients me more toward a man’s psychology than his body or his habits. You see a waspish cripple. I see a mind which has reacted to its physical handicaps by developing such a hellish energy, such an inhuman power of concentration, that it almost frightens me. Give that mind a sound body for its use and nothing is impossible to it.”

  “You may be right, at that,” murmured Viken after a pause. “Not that it matters. The decision is taken, the rockets go down tomorrow. I hope it all works out.”

  He waited for another while. The whirring of ventilators in his little room seemed unnaturally loud, the colors of a girlie picture on the wall shockingly garish. Then he said slowly, “You’ve been rather close-mouthed yourself, Jan. When do you expect to finish your own esprojector and start making the tests?”

  Cornelius looked around. The door stood open to an empty hallway, but he reached out and closed it before he answered with a slight grin, “It’s been ready for the past few days. But don’t tell anyone.”

  “How’s that?” Viken started. The movement, in low gee, took him out of his chair and halfway across the table between the men. He shoved himself back and waited.

  “I have been making meaningless, tinkering motions,” said Cornelius, “but what I waited for was a highly emotional moment, a time when I can be sure Anglesey’s entire attention will be focused on Joe. This business tomorrow is exactly what I need.”

  “Why?”

  “You see, I have pretty well convinced myself that the trouble in the machine is psychological, not physical. I think that for some reason, buried in his subconscious, Anglesey doesn’t want to experience Jupiter. A conflict of that type might well set a psionic-amplifier circuit oscillating.”

  “Hm-m-m.” Viken rubbed his chin. “Could be. Lately Ed has been changing more and more. When he first came here, he was peppery enough, and he would at least play an occasional game of poker. Now he’s pulled so far into his shell you can’t even see him. I never thought of it before, but…yes, by God, Jupiter must be having some effect on him.”

  “Hm-m-m.” Cornelius nodded. He did not elaborate—did not, for instance, mention that one altogether uncharacteristic episode when Anglesey had tried to describe what it was like to be a Jovian.

  “Of course,” said Viken thoughtfully, “the previous men were not affected especially. Nor was Ed at first, while he was still controlling lower-type pseudos. It’s only since Joe went down to the surface that he’s become so different.”

  “Yes, yes,” said Cornelius hastily. “I’ve learned that much. But enough shop talk—”

  “No. Wait a minute.” Viken spoke in a low, hurried tone, looking past him. “For the first time, I’m starting to think clearly about this. Never really stopped to analyze it before, just accepted a bad situation. There is something peculiar about Joe. It can’t very well involve his physical structure, or the environment, because lower forms didn’t give this trouble. Could it be the fact that Joe is the first puppet in all history with a potentially human intelligence?”

  We speculate in a vacuum,” said Cornelius. “Tomorrow, maybe I can tell you. Now I know nothing.”

  Viken sat up straight. His pale eyes focused on the other man and stayed there, unblinking. “One minute,” he said.

  “Yes?” Cornelius shifted, half rising. “Quickly, please. It is past my bedtime.”

  “You know a good deal more than you’ve admitted,” said Viken. “Don’t you?”

  “What makes you think that?”

  “You aren’t the most gifted liar in the universe. And then, you argued very strongly for Anglesey’s scheme, this sending down the other pseudos. More strongly than a newcomer should.”

  “I told you, I want his attention focused elsewhere when—”

  “Do you want it that badly?” snapped Viken.

  Cornelius was still for a minute. Then he sighed and leaned back.

  “All right,” he said. “I shall have to trust your discretion. I wasn’t sure, you see, how any of you old-time station personnel would react. So I didn’t want to blabber out my speculations, which may be wrong. The confirmed facts, yes, I will tell them; but I don’t wish to attack a man’s religion with a mere theory.”

  Viken scowled. “What the devil do you mean?”

  Cornelius puffed hard on his cigar; its tip waxed and waned like a miniature red demon star. “This Jupiter Five is more than a research station,” he said gently. “It is a way of life, is it not? No one would come here for even one hitch unless the work was important to him. Those who re-enlist, they must find something in the work, something which Earth with all her riches cannot offer them. No?”

  “Yes,” answered Viken. It was almost a whisper. “I didn’t think you would understand so well. But what of it?”

  “Well, I don’t want to tell you, unless I can prove it, that maybe this has all gone for nothing. Maybe you have wasted your lives and a lot of money, and will have to pack up and go home.”

  Viken’s long face did not flicker a muscle. It seemed to have congealed. But he said calmly enough, “Why?”

  “Consider Joe,” said Cornelius. “His brain has as much capacity as any adult human’s. It has been recording every sense datum that came to it, from the moment of ‘birth’—making a record in itself, in its own cells, not merely in Anglesey’s physical memory bank up here. Also, you know, a thought is a sense datum, too. And thoughts are not separated into neat little railway tracks; they form a continuous field. Every time Anglesey is in rapport with Joe, and thinks, the thought goes through Joe’s synapses as well as his own—and every thought carries its own associations, and every associated memory is recorded. Like if Joe is building a hut, the shape of the logs might remind Anglesey of some geometric figure, which in turn would remind him of the Pythagorean theorem—”

  “I get the idea,” said Viken in a cautious way. “Given time, Joe’s brain will have stored everything that ever was in Ed’s.”
