The Human Edge
* * *
When he woke, it was night, and he could not quite remember where he was or why. His thoughts seemed numb and unimportant. But he was cold, so he blundered about until he found the standing half-trunk of a lightning-blasted tree and crept into the burned hollow of its interior, raking frill-edged, alien leaves about him out of some half-forgotten instinct, until his own body warmth in the leaves formed a cocoon of comfort about him; and he slept.
From then on began a period in which nothing was very clear. It was as if his mind had huddled itself away somehow like a wounded animal and refused to think. There was no past or future, only the endless now. If now was warm, it had always been warm; if dark—it had always been dark. He learned to smell water from a distance and go to it when he was thirsty. He put small things in his mouth to taste them. If they tasted good he ate them. If he got sick afterward, he did not eat them again.
Gradually, blindly, the world about him began to take on a certain order. He came to know where there were plants with portions he could eat, where there were small creatures he could catch and pull apart and eat, and where there was water.
He did not know how lucky he was in the sheer chance of finding flora and fauna on an alien world that were edible—let alone nourishing. He did not realize that he had come down on a plateau in the tropical highlands, with little variation in day and night temperature and no large native predators which might have attacked him.
None of this he knew. Nor would it have made any difference to him if he had, for the intellectual center of his brain had gone on vacation, so to speak, and refused to be called back. He was, in fact, a victim of severe psychological shock. The shock of someone who had come to feel himself absolute master of a universe and who then, in a few short seconds, had been cast down from that high estate by something or someone inconceivably greater, into the state of a beast of the field.
But still, he could not be a true beast of the field, in spite of the fact his intellectual processes had momentarily abdicated. His perceptive abilities still worked. His eyes could not help noting, even if incuriously, the progressive drying of the vegetation, the day-by-day shifting in the points of setting and rising of the sun. Slowly, instinctively, the eternal moment that held him stretched and lengthened until he began to perceive divisions within it—a difference between now and was, between now and will be.

The day came at last when he saw himself.
A hundred times he had crouched by the water to drink and, lowering his lips to its surface, seen color and shape rising to meet him. The hundredth and something time, he checked, a few inches above the liquid plane, staring at what he saw.
For several long seconds it made no sense to him. Then, at first slowly, then with a rush like pain flooding back on someone rousing from the anesthesia of unconsciousness, he recognized what he saw.
Those were eyes at which he stared, sunken and dark-circled under a dirty tangle of hair. That was a nose jutting between gaunt and sunken cheeks above a mouth, and there was a chin naked only because once an ultrafine laser had burned out the thousand and one roots of the beard that grew on it. That was a man he saw—himself.
He jerked back like someone who has come face-to-face with the devil. But he returned eventually, because he was thirsty, to drink and see himself again. And so, gradually, he got used to the sight of himself.
So it was that memory started to return to him. But it did not come back quickly or all at once. It returned instead by jerks and sudden, partial revelations—until finally the whole memory of what had happened was back in his conscious mind again.
But he was really not a man again.
He was still essentially what the operator of the pyramid had broken him down into. He was still an animal. Only the memory and imaginings of a man had returned to live like a prisoner in a body that went on reacting and surviving in the bestial way it had come to regard as natural.
But his animal peace was broken. For his imprisoned mind worked now. With the control-suit broken up—he had returned to the spot of its destruction many times, to gaze beastlike at the rusting parts—his mind knew he was a prisoner, alone on this alien world until he died. To know that was not so bad, but remembering this much meant remembering also the existence of the someone or something that had made him a prisoner here.
The whoever it was who was in the pyramid.
That the pyramid might have been an automated, mechanical device never entered his mind for a moment. There had been a personal, directed, living viciousness behind the announcement that had condemned him to live as a beast. No, in that blank-walled, metallic structure, whose treaded mechanical servants still prospected through the woods, there was something alive—something that could treat the awesome power of a solar tap as a human treated the attack of a mosquito—but something living. Some being. Some Other, who lived in the pyramid, moving, breathing, eating, and gloating—or worse yet, entirely forgetful of what he had done to Harry Brennan.
And now that he knew that the Other was there, Harry began to dream of him nightly. At first, in his dreams, Harry whimpered with fear each time the dark shape he pursued seemed about to turn and show its face. But slowly, hatred came to grow inside and then outside his fear. Unbearable that Harry should never know the face of his destroyer. Lying curled in the nest of leaves under the moonless, star-brilliant sky, he snarled, thinking of his deprivation.
Then hate came to strengthen him in the daylight also. From the beginning he had avoided the pyramid, as a wild coyote avoids the farmyard where he was once shot by the farmer. But now, day after day, Harry circled closer to the alien shape. From the beginning he had run and hidden from the treaded prospecting machines. But now, slowly, he grew bolder, standing close enough at last to touch them as they passed. And he found that they paid no attention to him. No attention at all.
* * *
He came to ignore them in turn, and day by day he ventured closer to the pyramid. Until the morning came when he lay, silently snarling, behind a bush, looking out across the tread-trampled space that separated him from the nearest copper-colored face of the pyramid.
The space was roughly circular, thirty yards across, broken only by a small stream which had been diverted to loop inward toward the pyramid before returning to its original channel. In the bight of the loop a machine like a stork straddled the artificial four-foot-wide channel, dipping a pair of long necks with tentacle-clustered heads into the water at intervals. Sometimes Harry could see nothing in the tentacles when they came up. Occasionally they carried some small water creature which they deposited in a tank.
Making a perfect circle about the tramped area, so that the storklike machine was guarded within them, was an open fence of slender wands set upright in the earth, far enough apart for any of the machines that came and went to the forest to pass between any two of them. There seemed to be nothing connecting the wands, and nothing happened to the prospecting machines as they passed through—but the very purposelessness of the wands filled Harry with uneasiness.
It was not until after several days of watching that he had a chance to see a small native animal, frightened by something in the woods behind it, attempt to bolt across a corner of the clearing.
As it passed between two of the wands there was a waveriness in the air between them. The small animal leaped high, came down, and lay still. It did not move after that, and later in the day, Harry saw the indifferent treads of one of the prospecting machines bury it in the trampled earth in passing.
That evening, Harry brought several captive, small animals bound with grass up to the wand line and thrust them through, one by one at different spots. All died.
The next night he tried pushing a captive through a small trench scooped out so that the creature passed the killing line below ground level. But this one died also. For several days he was baffled. Then he tried running behind a slow-moving machine as it returned and tying a small animal to it with grass.
/>
For a moment as the front of the machine passed through, he thought the little animal would live. But then, as the back of the machine passed the line, it, too, died.
Snarling, Harry paced around outside the circle in the brush until the sun set and stars filled the moonless sky.
* * *
In the days that followed, he probed every gap in the wand-fence, but found no safe way through it. Finally, he came to concentrate on the two points at which the diverted stream entered and left the circle to flow beneath the storklike machine.
He studied this without really knowing what he was seeking. He did not even put his studying into words. Vaguely, he knew that the water went in and the water came out again unchanged; and he also wished to enter and come out safely. Then, one day, studying the stream and the machine, he noticed that a small creature plucked from the water by the storklike neck's mass of tentacles was still wriggling.
That evening, at twilight, while there was still light to see, he waded up the two-foot depth of the stream to the point where the killing line cut across its watery surface and pushed some more of his little animals toward the line underwater.
Two of the three surfaced immediately, twitched, and floated on limply, to be plucked from the water and cast aside on the ground by the storklike machine. But the third swam on several strokes before surfacing and came up living to scramble ashore, race for the forest, and be killed by wands further around the circle.
Harry investigated the channel below the killing line. There was water there up to his midthigh, plenty to cover him completely. He crouched down in the water and took a deep breath.
Ducking below the surface, he pulled himself along with his fingertips, holding himself close to the bottom. He moved in as far as the tentacled ends. These grabbed at him, but could not reach far enough back to touch him. He saw that they came within a few inches of the gravel bottom.
He began to need air. He backed carefully out and rose above the water, gasping. After a while his hard breathing stopped, and he sat staring at the water for a long while. When it was dark, he left.
The next day he came and crept underwater to the grabbing area of the storklike machine again. He scooped out several handfuls of the gravel from under the place where the arms grabbed, before he felt a desperate need for air and had to withdraw. But that day began his labors.
IV
Four days later the bottom under the grasping tentacles was scooped out to an additional two feet of depth. And the fifth twilight after that, he pulled himself, dripping and triumphant, up out of the bend of the diverted stream inside the circle of the killing wands.
He rested and then went to the pyramid, approaching it cautiously and sidelong like a suspicious animal. There was a door in the side he approached through which he had seen the prospecting machines trundle in and out. In the dimness he could not see it; and when he touched the metallic side of the structure, his fingers, grimed and toughened from scrabbling in the dirt, told him little. But his nose, beast-sensitive now, located and traced the outline of the almost invisible crack around the door panel by its reek of earth and lubricant.
He settled down to wait. An hour later, one of the machines came back. He jumped up, ready to follow it in; but the door opened just before it and closed the minute it was inside—nor was there any room to squeeze in beside it. He hunkered down, disappointed, snarling a little to himself.
He stayed until dawn and watched several more machines enter and leave. But there was no room to squeeze inside, even with the smallest of them.
During the next week or so he watched the machines enter and leave nightly. He tied one of his small animals to an entering machine and saw it pass through the entrance alive and scamper out again with the next machine that left. And every flight his rage increased. Then, wordlessly, one daytime after he had seen a machine deep in the woods lurch and tilt as its tread passed over a rock, inspiration took him.
That night he carried through the water with him several cantaloupe-sized stones. When the first machine came back to the pyramid, in the moment in which the door opened before it, he pushed one of the rocks before the right-hand tread. The machine, unable to stop, mounted the rock with its right tread, tilted to the left, and struck against that side of the entrance.
It checked, backed off, and put out an arm with the grasping end to remove the rock. Then it entered the opening. But Harry was already before it, having slipped through while the door was still up and the machine busy pulling the stone aside.
He plunged into a corridor of darkness, full of clankings and smells. A little light from the opening behind him showed him a further, larger chamber where other machines stood parked. He ran toward them.
Long before he reached them, the door closed behind him, and he was in pitch darkness. But the clanking of the incoming machine was close behind him, and the adrenalinized memory of a wild beast did not fail him. He ran, hands outstretched, directly into the side of the parked machine at which he had aimed and clambered up on it. The machine entering behind him clanked harmlessly past him and stopped moving.
He climbed cautiously down in the impenetrable darkness. He could see nothing; but the new, animal sensitivity of his nose offered a substitute for vision. He moved like a hunting dog around the chamber, sniffing and touching; and slowly a clear picture of it and its treaded occupants built up in his mind.
He was still at this when suddenly a door he had not seen opened almost in his face. He had just time to leap backward as a smaller machine with a boxlike body and a number of upward-thrusting arms entered, trundled to the machine that had just come back, and began to relieve the prospecting machine of its sample box, replacing it with the one it carried itself.
This much, in the dim light from the open door, Harry was able to see. But then, the small machine turned back toward the doorway; and Harry, waking to his opportunity, ducked through ahead of it.
* * *
He found himself in a corridor dimly lit by a luminescent strip down the center of the ceiling. The corridor was wide enough for the box-collecting machine to pass him; and, in fact, it rolled out around him as he shrank back against one metal wall. It went on down the corridor, and he followed it into a larger room with a number of machines, some mobile, some not, under a ceiling lit as the corridor had been with a crossing of luminescent strip.
In this area all the machines avoided each other—and him. They were busy with each other and at other incomprehensible duties. Hunched and tense, hair erect on the back of his neck and nostrils spread wide, Harry moved through them to explore other rooms and corridors that opened off this one. It took him some little time; but he discovered that they were all on a level, and there was nothing but machines in any of them. He found two more doors with shallow steps leading up to them, but these would not open for him; and though he watched by one for some time, no machine went up the steps and through it.
He began to be conscious of thirst and hunger. He made his way back to the door leading to the chamber where the prospecting machines were parked. To his surprise, it opened as he approached it. He slipped through into darkness.
Immediately, the door closed behind him; and sudden panic grabbed him, when he found he could not open it from this side. Then, self-possession returned to him.
By touch, smell, and memory, he made his way among the parked machines and down the corridor to the outside door. To his gratification, this also opened when he came close. He slipped through into cool, fresh outer air and a sky already graying with dawn. A few moments later, wet but free, he was back in the woods again.
From then on, each night he returned. He found it was not necessary to do more than put any sizable object before the returning machine. It would stop to clear the path, and he could enter ahead of it. Then, shortly after he was inside, a box-collecting machine would open the inner door.
Gradually, his fear of the machines faded. He came to hold them in a certain contempt. They always did
the same thing in the same situation, and it was easy to trick or outmaneuver them.
But the two inner doors of the machine area with the steps would not open to him; and he knew the upper parts of the pyramid were still unexplored by him. He sniffed at the cracks of these doors, and a scent came through—not of lubricating medium and metal alone, but of a different, musky odor that raised the hairs on the back of his neck again. He snarled at the doors.
* * *
He went back to exploring minutely the machine level. The sample boxes from the prospecting machines, he found, were put on conveyor-beltlike strips that floated up on thin air through openings in the ceiling—but the openings were too small for him to pass through. But he discovered something else. One day he came upon one of the machines taking a grille off the face of one of the immobile devices. It carried the grille away, and he explored the opening that had been revealed. It was the entrance to a tunnel or duct leading upward; and it was large enough to let him enter it. Air blew silently from it; and the air was heavy with the musky odor he had smelled around the doors that did not open.
The duct tempted him, but fear held him back. The machine came back and replaced the grille; and he noticed that it fitted into place with a little pressure from the outside, top and bottom. After the machine had left he pressed, and the grille fell out into his hands.
After a long wait, he ventured timorously into the tube—but a sudden sound like heavy breathing mixed with a wave of a strong, musky odor came at him. He backed out in panic, fled the pyramid, and did not come back for two days.
When he came back, the grille was again neatly in place. He removed it and sat a long time getting his courage up. Finally, he put the grille up high out of reach of the machine which had originally removed it and crawled into the duct.
