The Minimum Man
Robert Sheckley
Galaxy, June 1958

Everybody has his song, thought Anton Perceveral. A pretty girl is like a melody, and a brave spaceman like a flurry of trumpets. Wise old men on the Interplanetary Council make one think of richly blended woodwinds. There are geniuses whose lives are an intricate counterpoint endlessly embellished, and scum of the planets whose existence seems nothing more than the wail of an oboe against the inexorable pounding of a bass drum.

Perceveral thought about this, loosely gripping a razor blade and contemplating the faint blue veins in his wrist.

For if everybody has his song, his could be likened to a poorly conceived and miserably executed symphony of errors.

There had been muted horns of gladness at his birth. Bravely, to the sound of muffled drums, young Perceveral had ventured into school. He had excelled and been promoted to a small workshop class of five hundred pupils, where he could receive a measure of individual attention. The future had looked promising.

But he was congenitally unlucky. There was a constant series of small accidents with overturned inkwells, lost books and misplaced papers. Things had a damnable propensity for breaking under his fingers; or sometimes his fingers broke under things. To make matters worse, he caught every possible childhood disease, including proto-Measles, Algerian Mumps, Impetigo, Foxpox, Green Fever and Orange Fever.

These things in no way reflected upon Perceveral's native ability; but one needs more than ability in a crowded and competitive world. One needs considerable luck, and Perceveral had none. He was transferred to an ordinary class of ten thousand students, where his problems were intensified and his opportunities for catching disease expanded.

He was a tall, thin, bespectacled, goodhearted, hard-working young man whom the doctors early diagnosed as accident-prone, for reasons which defied their analysis. But whatever the reasons, the facts remained. Perceveral was one of those unhappy people for whom life is difficult to the point of impossibility.

Most people slip through the jungle of human existence with the facility of prowling panthers. But, for the Perceverals, the jungle is continually beset with traps, snares and devices, sudden precipices and unfordable streams, deadly fungus and deadlier beasts. No way is safe. All roads lead to disaster.

Young Perceveral won his way through college in spite of his remarkable talent for breaking his leg on winding staircases, twisting his ankle on curbstones, fracturing his elbow in revolving doors, smashing his glasses against plate-glass windows, and all the rest of the sad, ludicrous, painful events which beset the accident-prone. Manfully he resisted the solace of hypochondria and kept trying.

Upon graduation from college, Perceveral took himself firmly in hand and tried to reassert the early clear theme of hope set by his stalwart father and gentle mother. With a ruffle of drums and a trilling of chords, Perceveral entered the island of Manhattan, to forge his destiny. He worked hard to conquer his unhappy predisposition, and to stay cheerful and optimistic in spite of everything.

But his predisposition caught up with him. The noble chords dissolved into vague mutterings, and the symphony of his life degenerated to the level of opéra bouffe. Perceveral lost job after job in a snarl of broken voxwriters and smeared contracts, forgotten file cards and misplaced data sheets; in a mounting crescendo of ribs wrenched in the subway rush, ankles sprained on gratings, glasses smashed against unseen projections, and in a bout of illnesses which included Hepatitis Type J, Martian Flu, Venusian Flu, Waking Sickness and Giggling Fever.

Perceveral still resisted the lure of hypochondria. He dreamed of space, of the iron-jawed adventurers advancing Man's frontier, of the new settlements on distant planets, of vast expanses of open land where, far from the hectic plastic jungles of Earth, a man could really find himself. He applied to the Planetary Exploration & Settlement Board, and was turned down. Reluctantly he pushed the dream aside and tried a variety of jobs. He underwent Analysis, Hypnotic Suggestion, Hypnotic Hypersuggestion and Countersuggestion Removal -- all to no avail.

Every man has his limits and every symphony has its end. Perceveral gave up hope at the age of thirty-four when he was fired, after three days, from a job he had sought for two months. That, as far as he was concerned, provided the final humorous off-key cymbal clash to something which probably shouldn't have been started in the first place.

Grimly he took his meager paycheck, accepted a last wary handshake from his former employer, and rode the elevator to the lobby. Already vague thoughts of suicide were crossing his mind in the form of truck wheels, gas pipes, tall buildings and swift rivers.

The elevator reached the great marble lobby with its uniformed riot policemen and its crowds waiting admittance to the mid-town streets. Perceveral waited in line, idly watching the Population Density Meter fluctuate below the panic line, until his turn came. Outside, he joined a compact body of people moving westward in the direction of his housing project.

Suicidal thoughts continued to flow through his mind, more slowly now, taking more definite forms. He considered methods and means until he reached home. There he disengaged himself from the crowd and slipped in through an entry port.

He struggled against a flood of children pouring through corridors, and reached his city-provided cubicle. He entered, closed and locked the door, and took a razor blade from his shaving kit. He lay down on the bed, propping his feet against the opposite wall, and contemplated the faint blue veins of his wrist.

Could he do it? Could he do it cleanly and quickly, without error and without regret? Or would he bungle this job, too, and be dragged screaming to a hospital, a ludicrous sight for the interns to snicker about?

As he was thinking, a yellow envelope was slipped under his door. It was a telegram, arriving pat on the hour of decision, with a melodramatic suddenness which Perceveral considered quite suspect. Still, he put down the razor blade and picked up the envelope.

It was from the Planetary Exploration & Settlement Board, the great organization that controlled every Earthman's movements in space. With trembling fingers, Perceveral opened the envelope and read:

Mr. Anton Perceveral Temporary Housing Project 1993 District 43825, Manhattan 212, N.Y.

Dear Mr. Perceveral:

Three years ago you applied to us for a position in any off-Earth capacity. Regretfully we had to turn you down at that time. Your records have been kept on file, however, and have recently been brought up to date. I am happy to inform you that a position is immediately available for you, one which I consider well suited to your particular talents and qualifications. I believe this job will meet with your approval, carrying, as it does, a salary of $20,000 a year, all government fringe benefits, and an unexcelled opportunity for advancement. Could you come in and discuss it with me?

Sincerely, William Haskell Asst. Placement Director

WH/ibm3dc

Perceveral folded the telegram carefully and put it back in its envelope. His first feeling of intense joy vanished, to be replaced by a sense of apprehension.

What talents and qualifications did he have for a job commanding twenty thousand a year and benefits? Could they be confusing him with a different Anton Perceveral?

It seemed unlikely. The Board just didn't do that sort of thing. And presuming that they knew him and his ill-starred past -- what could they possibly want from him? What could he do that practically any man, woman or child couldn't do better?

Perceveral put the telegram in his pocket and replaced the razor blade in his shaving kit. Suicide seemed a little premature now. First he would find out what Haskell wanted.

At the headquarters of the Planetary Exploration & Settlement Board, Perceveral was admitted at once to William Haskell's private office. The Assistant Placement Director was a large, blunt-featured, white-haired man who radiated a geniality which Perceveral found suspicious.

"Sit down, sit down, Mr. Perceveral," Haskell said. "Cigarette? Care for a drink? Awfully glad you could make it."

"Are you sure you have the right man?" Perceveral asked.

Haskell glanced through a dossier on his desk. "Let's see. Anton Perceveral; age thirty-four; parents, Gregory James Perceveral and Anita Swaans Perceveral, Laketown, New Jersey. Is that right?"

"Yes," Perceveral said. "And you have a job for me?"

"We have indeed."

"Paying twenty thousand a year and benefits?"

"Perfectly correct."

"Could you tell me what the job is?"

"That's what we're here for," Haskell said cheerfully. "The job I have in mind for you, Mr. Perceveral, is listed in our catalogue as Extraterrestrial Explorer."

"I beg your pardon?"

"Extraterrestrial or alien-planet explorer," Haskell said. "The explorers, you know, are the men who make the first contacts on alien planets, the primary settlers who gather our essential data. I think of them as the Drakes and Magellans of this century. It is, I think you'll agree, an excellent opportunity."

Perceveral stood up, his face a dull red. "If you're finished with the joke, I'll leave."

"Eh?"

"Me an extraterrestrial explorer?" Perceveral said with a bitter laugh. "Don't try to kid me. I read the papers. I know what the explorers are like."

"What are they like?"

"They're Earth's finest," Perceveral said. "The very best brains in the very best bodies. Men with trigger-quick reactions, able to tackle any problem, cope with any situation, adjust to any environment. Isn't that true?"

"Well," Haskell said, "it was true back in the early days of planetary exploration. And we have allowed that stereotype to remain in the public eye, to instill confidence. But that type of explorer is now obsolete. There are plenty of other jobs for men such as you describe. But not planetary exploration."

"Couldn't your supermen make the grade?" Perceveral asked with a faint sneer.

"Of course they could," Haskell said. "No paradox is involved here. The record of our early explorers is unsurpassed. Those men managed to survive on every planet where human survival was even remotely possible, against overwhelming odds, by sheer grit and tenacity. The planets called for their every resource and they rose to meet the challenge. They stand as an eternal monument to the toughness and adaptability of Homo sapiens."

"Then why did you stop using them?"

"Because our problems on Earth changed," Haskell told him. "In the early days, the exploration of space was an adventure, a scientific achievement, a defense measure, a symbol. But that passed. Earth's overpopulation trend continued -- explosively. Millions spilled into relatively empty lands like Brazil, New Guinea and Australia. But the population explosion quickly filled them. In major cities, the population panic point was reached and produced the Weekend Riots. And the population, bolstered by geriatrics and a further sharp decrease in infant mortality, continued to grow."

Haskell rubbed his forehead. "It was a mess. But the ethics of population increase aren't my business. All we at the Board knew was, we had to have new land fast. We needed planets which -- unlike Mars and Venus -- would be rapidly self-supporting. Places to which we could siphon millions, while the scientists and politicians on Earth tried to straighten things out. We had to open these planets to colonization as rapidly as possible. And that meant speeding up the initial exploratory process."

"I know all that," Perceveral said. "But I still don't see why you stopped using the optimum explorer type."

"Isn't it obvious? We were looking for places where ordinary people could settle and survive. Our optimum explorer type was not ordinary. Quite the contrary, he almost approximated a new species. And he was no judge of ordinary survival conditions. For example, there are bleak, dreary, rain-swept little planets that the average colonist finds depressing to the point of insanity; but our optimum explorer is too sound to be disturbed by climatic monotony. Germs which devastate thousands give him, at most, a bad time for a while. Dangers which can push a colony to the brink of disaster, our optimum explorer simply evades. He can't assess these things in everyday terms. They simply don't touch him."

"I'm beginning to see," Perceveral said.

"Now the best way," Haskell said, "would have been to attack these planets in stages. First an explorer, then a basic research team, then a trial colony composed largely of psychologists and sociologists, then a research group to interpret the findings of the other groups, and so forth. But there's never enough time or money for all that. We need those colonies right now, not in fifty years."

Mr. Haskell paused and looked hard at Perceveral. "So, you see, we must have immediate knowledge as to whether a group of ordinary people could live and thrive on any new planet. That's why we changed our qualifications for explorers."

Perceveral nodded. "Ordinary explorers for ordinary people. There's just one thing, however."

"Yes?"

"I don't know how well you know my background . . ."

"Quite well," Haskell assured him.

"Then you might have noticed that I have certain tendencies toward -- well, a certain accident-proneness. To tell you the honest truth, I have a hard time surviving right here on Earth."

"I know," Mr. Haskell said pleasantly.

"Then how would I make out on an alien planet? And why would you want me?"

Mr. Haskell looked slightly ill at ease. "Well, you stated our position wrongly when you said 'ordinary explorers for ordinary people.' It isn't that simple. A colony is composed of thousands, often millions of people, who vary considerably in their survival potentialities. Humanity and the law state that all of them must have a fighting chance. The people themselves must be reassured before they'll leave Earth. We must convince them -- and the law -- and ourselves -- that even the weakest will have a chance for survival."

"Go on," Perceveral said.

"Therefore," Haskell said quickly, "some years ago we stopped using the optimum-survival explorer, and began using the minimum-survival explorer."

Perceveral sat for a while digesting this information. "So you want me because any place I can live in, anyone can live in."

"That more or less sums up our thinking on the problem," Haskell said, smiling genially.

"But what would my chances be?"

"Some of our minimum-survival explorers have done very well."

"And others?"

"There are hazards, of course," Haskell admitted. "And aside from the potential dangers of the planet itself, there are other risks involved in the very nature of the experiment. I can't even tell you what they are, since that would destroy our only control element on the minimum-survival test. I simply tell you that they are present."

"Not a very good outlook," Perceveral said.

"Perhaps not. But think of the rewards if you won through! You would, in effect, be the founding father of a colony! Your value as an expert would be immeasurable. You would have a permanent place in the life of the community. And equally important, you might be able to dispel certain insidious self-doubts concerning your place in the scheme of things."

Perceveral nodded reluctantly. "Tell me one thing. Your telegram arrived today at a particularly crucial moment. It seemed almost -- "

"Yes, it was planned," Haskell said. "We've found that the people we want are most receptive when they've reached a certain psychological state. We keep close watch over the few who fit our requirements, waiting for the right moment to make our presentation."

"It might have been embarrassing if you'd been an hour later," Perceveral said.

"Or unfruitful if we'd been a day earlier." Haskell arose from behind his desk. "Would you join me for lunch, Mr. Perceveral? We can discuss final details over a bottle of wine."

"All right," Perceveral said. "But I'm not making any promises yet."

"Of course not," Haskell said, opening the door for him.

After lunch Perceveral did some hard thinking. The explorer's job appealed to him strongly in spite of the risks. It was, after all, no more dangerous than suicide, and much better paying. The rewards were great if he won; the penalty for failure was no more than the price he had been about to pay for failure on Earth.

He hadn't done well in thirty-four years on Earth. The best he had shown were flashes of ability marred by a strong affinity for illness, accident and blunder. But Earth was crowded, cluttered and confused. Perhaps his accident-proneness had been not some structural flaw in him but the product of intolerable conditions.

Exploration would give him a new environment. He would be alone, dependent only on himself, answerable only to himself. It would be tremendously dangerous -- but what could be more dangerous than a glittering razor blade held in his own hand?

This would be the supreme effort of his life, the ultimate test. He would fight as he had never fought before to conquer his fatal tendencies. And this time he would throw every ounce of strength and determination into the struggle.

He accepted the job. In the next weeks of preparation he ate and drank and slept determination, hammered it into his brain and wove it between his nerves, mumbled it to himself like a Buddhist prayer, dreamed about it, brushed his teeth and washed his hands with it, meditated upon it until the monotonous refrain buzzed in his head waking and sleeping, and began slowly to act as a check and restraint upon action.

The day arrived when he was assigned a year's tour of duty upon a promising planet in the East Star Ridge. Haskell wished him luck and promised to stay in touch by L-phase radio. Perceveral and his equipment were put aboard the picket ship Queen of Glasgow, and the adventure was begun.

During the months in space, Perceveral continued to think obsessively of his resolve. He handled himself carefully in no-weight, watched his every movement and cross-checked his every motive. This continuous inspection slowed him down considerably; but gradually it became habitual. A set of new reflexes began to form, struggling to conquer the old reflex system.

But progress was spasmodic. In spite of his efforts, Perceveral caught a minor skin irritation from the ship's purification system, broke one of his ten pairs of glasses against a bulkhead, and suffered numerous headaches, backaches, skinned knuckles and stubbed toes.

Still, he felt he had made progress, and his resolution hardened accordingly. And at last his planet came into view.

The planet was named Theta. Perceveral and his equipment were set down on a grassy, forested upland near a mountain range. The area had been preselected by air survey for its promising qualifies. Water, wood, local fruits and mineral-bearing ores were all nearby. The area could make an excellent colony site.

The ship's officers wished him luck, and departed. Perceveral watched until the ship vanished into a bank of clouds. Then he went to work.

First he activated his robot. It was a tall, gleaming, black multipurpose machine, standard equipment for explorers and settlers. It couldn't talk, sing, recite or play cards like the more expensive models. Its only response was a head-shake or a nod; dull companionship for the year ahead. But it was programed to handle verbal work commands of a considerable degree of complexity, to perform the heaviest labor, and to show a degree of foresight in problem situations.

With the robot's help, Perceveral set up his camp on the plain, keeping a careful check on the horizon for signs of trouble. The air survey had detected no signs of an alien culture, but you could never tell. And the nature of Theta's animal life was still uninvestigated.

He worked slowly and carefully, and the silent robot worked beside him. By evening, he had set up a temporary camp. He activated the radar alarm and went to bed.

He awoke just after dawn to the shrilling of the radar alarm bell. He dressed and hurried outside. There was an angry humming in the air, like the sound of a locust horde.

"Get two beamers," he told the robot, "and hurry back. Bring the binoculars, too."

The robot nodded and lurched off. Perceveral turned slowly, shivering in the gray dawn, trying to locate the direction of the sound. He scanned the damp plain, the green edge of forest, the cliffs beyond. Nothing moved. Then he saw, outlined against the sunrise, something that looked like a low dark cloud. The cloud was flying toward his camp, moving very quickly against the wind.

The robot returned with the beamers. Perceveral took one and directed the robot to hold the other, awaiting orders to fire. The robot nodded, his eye cells gleaming dully as he turned toward the sunrise.

When the cloud swept nearer, it resolved into a gigantic flock of birds. Perceveral studied them through his binoculars. They were about the size of Terran hawks, but their darting, erratic flight resembled the flight of bats. They were heavily taloned and their long beaks were edged with sharp teeth. With all that lethal armament, they had to be carnivorous.

The flock circled them, humming loudly. Then, from all directions, with wings swept back and talons spread, they began to dive. Perceveral directed the robot to begin firing.

He and the robot stood back to back, blasting into the onslaught of birds. There was a whirling confusion of blood and feathers as battalions of birds were scythed out of the sky. Perceveral and the robot were holding their own, keeping the aerial wolf pack at a distance, even beating it back. Then Perceveral's beamer failed.

The beamers were supposed to be fully charged and guaranteed for seventy-five hours at full automatic. A beamer couldn't fail! He stood for a moment, stupidly clicking the trigger. Then he flung down the weapon and hurried to the supplies tent, leaving the robot to continue the fight alone.

He located his two spares and came out. When he rejoined the battle, he saw that the robot's beamer had stopped functioning. The robot stood erect, beating off the swarm of birds with his arms. Drops of oil sprayed from his joints as he flailed at the dense flock. He swayed, dangerously close to losing his balance, and Perceveral saw that some birds had evaded his swinging arms and were perched on his shoulders, pecking at his eye cells and kinesthetic antenna.

Perceveral swung up both beamers and began to cut into the swarm. One weapon failed almost immediately. He continued chopping with the last, praying it would retain its charge.

The flock, finally alarmed by its losses, rose and wheeled away, screaming and hooting. Miraculously unhurt, Perceveral and the robot stood knee-deep in scattered feathers and charred bodies.

Perceveral looked at the four beamers, three of which had failed him entirely. Then he marched angrily to the communications tent.

He contacted Haskell and told him about the attack of the birds and the failure of three beamers out of four. Red-faced with outrage, he denounced the men who were supposed to check an explorer's equipment. Then, out of breath, he waited for Haskell's apology and explanation.

"That" Haskell said, "was one of the control elements."

"Huh?"

"I explained it to you months ago," Haskell said. "We are testing for minimum-survival conditions. Minimum , remember? We have to know what will happen to a colony composed of people of varying degrees of proficiency. Therefore, we look for the lowest denominator."

"I know all that. But the beamers -- "

"Mr. Perceveral, setting up a colony, even on an absolute minimum basis, is a fantastically expensive operation. We supply our colonists with the newest and best in guns and equipment, but we can't replace things that stop functioning or are used up. The colonists have to use irreplaceable ammunition, equipment that breaks and wears out, food stores that become exhausted or spoiled -- "

"And that's what you've given me?" Perceveral asked.

"Of course. As a control, we have equipped you with the minimum of survival equipment. That's the only way we'll be able to predict how the colonists will make out on Theta."

"But it isn't fair! Explorers always get the best equipment!"

"No," Haskell said. "The old-style optimum-survival explorers did, of course. But we're testing for least potential, which must extend to equipment as well as to personality. I told you there would be risks."

"Yes, you did," Perceveral said. "But . . . All right. Do you have any other little secrets in store for me?"

"Not really," Haskell said, after a momentary pause. "Both you and your equipment are of minimum-survival quality. That about sums it up."

Perceveral detected something evasive in this answer, but Haskell refused to be more specific. They signed off and Perceveral returned to the chaos of his camp.

Perceveral and the robot moved their camp to the shelter of the forest for protection against further assaults by the birds. In setting up again, Perceveral noted that fully half of his ropes were badly worn, his electrical fixtures were beginning to burn out, and the canvas of his tents showed mildew. Laboriously he repaired everything, bruising his knuckles and skinning his palms. Then his generator broke down.

He sweated over it for three days, trying to figure out the trouble from the badly printed instruction book, written in German, that had been sent with the machine. Nothing seemed to be set up right in the generator and nothing worked. At last he discovered, by pure accident, that the book was meant for an entirely different model. He lost his temper at this and kicked the generator, almost breaking the little toe of his right foot.

Then he took himself firmly in hand and worked for another four days, figuring out the differences between his model and the model described, until he had the generator working again.

The birds found that they could plummet through the trees into Perceveral's camp, snatch food and be gone before the beamer could be leveled at them. Their attacks cost Perceveral a pair of glasses and a nasty wound on the neck. Laboriously he wove nets, and, with the robot's help, strung them in the branches above his camp.

The birds were baffled. Perceveral finally had time to check his food stores, and to discover that many of his dehydrated staples had been poorly processed, and others had become a host to an ugly air-borne fungus. Either way, it added up to spoilage. Unless he took measures now, he would be short of food during the Thetan winter.

He ran a series of tests on local fruits, grains, berries and vegetables. They showed several varieties to be safe and nourishing. He ate these, and broke into a spectacular allergy rash. Painstaking work with his medical kit gave him a cure for the allergy, and he set up a test to discover the guilty plant. But just as he was checking final results, the robot stamped in, upsetting test tubes and spilling irreplaceable chemicals.

Perceveral had to continue the allergy tests on himself, and to exclude one berry and two vegetables as unfit for his consumption.

But the fruits were excellent and the local grains made a fine bread. Perceveral collected seed, and, late in the Thetan spring, directed the robot to the tasks of plowing and planting.

The robot worked tirelessly in the new fields, while Perceveral did some exploring. He found pieces of smooth rock upon which characters had been scratched, and what looked like numbers, and even little stick-pictures of trees and clouds and mountains. Intelligent beings must have lived on Theta, he decided. Quite probably they still inhabited some parts of the planet. But he had no time to search for them.

When Perceveral checked his fields, he found that the robot had planted the seed inches too deep, in spite of his programed instructions. That crop was lost, and Perceveral planted the next by himself.

He built a wooden shack and replaced the rotting tents with storage sheds. Slowly he made his preparations for survival through the winter. And slowly he began to suspect that his robot was wearing out.

The great black all-purpose machine performed its tasks as before. But the robot's movements were growing increasingly jerky and his use of strength was indiscriminate. Heavy jars splintered in his grip and farming implements broke when he used them. Perceveral programed him for weeding the fields, but the robot's broad splay feet trampled the grain sprouts as his fingers plucked the weeds. When the robot went out to chop firewood, he usually succeeded in breaking the ax handle. The cabin shook when the robot entered, and the door sometimes left its hinges.

Perceveral wondered and worried about the robot's deterioration. There was no way he could repair it, for the robot was a factory-sealed unit, meant to be repaired only by factory technicians with special tools, parts and knowledge. All Perceveral could do was retire the robot from service. But that would leave him completely alone.

He programed increasingly simple tasks into the robot and took more work upon himself. Still the robot continued to deteriorate. Then one evening, when Perceveral was eating his dinner, the robot lurched against the stove and sent a pot of boiling rice flying.

With his new-found survival talents, Perceveral flung himself out of the way and the boiling mess landed on his left shoulder instead of his face.

That was too much. The robot was dangerous to have around. After dressing his burn, Perceveral decided to turn the robot off and continue the work of survival alone. In a firm voice, he gave the Dormancy Command.

The robot simply glared at him and moved restlessly around the cabin, not responding to a robot's most basic command.

Perceveral gave the order again. The robot shook his head and began to stack firewood.

Something had gone wrong. He would have to turn the robot off manually. But there was no sign of the usual cut-out switch anywhere on the machine's gleaming black surface. Nevertheless, Perceveral took out his tool kit and approached the robot.

Amazingly, the robot backed away from him, arms raised defensively.

"Stand stilll" Perceveral shouted.

The robot moved away until his back was against the wall.

Perceveral hesitated, wondering what was going wrong. Machines weren't permitted to disobey orders. And the willingness to give up life had been carefully structured into all robotic devices.

He advanced on the robot, determined to turn him off somehow. The robot waited until he was close, then swung an armored fist at him. Perceveral dodged out of the way and flung a wrench at the robot's kinesthetic antenna. The robot quickly retracted it and swung again. This time his armored fist caught Perceveral in the ribs.

Perceveral fell to the floor and the robot stood over him, his eye cells flaring red and his iron fingers opening and closing. Perceveral shut his eyes and waited for the coup de grâce. But the machine turned and left the shack, smashing the lock as he went.

In a few minutes Perceveral heard the sound of firewood being cut and stacked -- as usual.

With the aid of his medical kit, Perceveral taped up his side. The robot finished work and came back for further instructions. Shakily, Perceveral ordered him to a distant spring for water. The robot left, showing no further signs of aggression. Perceveral dragged himself to the radio shack.

"You shouldn't have tried to turn him off," Haskell said, when he heard what had happened. "He isn't designed to be turned off. Wasn't that apparent? For your own safety, don't try it again."

"But what's the reason?"

"Because -- as you've probably guessed by now -- the robot acts as our quality-control over you."

"I don't understand," Perceveral said. "Why do you need a quality-control?"

"Must I go through it all again?" Haskell asked wearily. "You were hired as a minimum-survival explorer. Not average. Not superior. Minimum. "

"Yes, but -- "

"Let me continue. Do you recall how you were during your thirty-four years on Earth? You were continually beset by accident, disease and general misfortune. That is what we wanted on Theta. But you've changed, Mr. Perceveral."

"I've certainly tried to change."

"Of course," Haskell said. "We expected it. Most of our minimum-survival explorers change. Faced with a new environment and a fresh start, they get a grip on themselves such as they've never had before. But it's not what we're testing for, so we have to compensate for the change. Colonists, you see, don't always come to a planet in a spirit of self-improvement And any colony has its careless ones, to say nothing of the aged, the infirm, the feeble-minded, the foolhardy, the inexperienced children, and so forth. Our minimum-survival standards are a guarantee that all of them will have a chance. Now are you beginning to understand?"

"I think so," Perceveral said.

"That's why we need a quality-control over you -- to keep you from acquiring the average or superior survival qualities which we are not testing for."

"Therefore the robot," Perceveral said bleakly.

"Correct. The robot has been programed to act as a check, a final control over your survival tendencies. He reacts to you, Perceveral. As long as you stay within a preselected range of general incompetence, the robot operates at par. But when you improve, become more skillful at survival, less accident-prone, the robot's behavior deteriorates. He begins to break the things that you should be breaking, to form the wrong decisions you should be forming -- "

"That isn't fair!"

"Perceveral, you seem to feel that we're running some kind of sanitorium or self-aid program for your benefit. Well, we're not. We're interested only in getting the job that we bought and paid for. The job, let me add, which you chose as an alternative to suicide."

"All right!" Perceveral shouted. "I'm doing the job. But is there any rule that says I can't dismantle that damned robot?"

"No rule at all," Haskell said in a quieter voice, "if you can do it. But I earnestly advise you not to try. It's too dangerous. The robot will not allow himself to be deactivated."

"That's for me to decide, not him," Perceveral said, and signed off.

Spring passed on Theta, and Perceveral learned how to live with his robot. He ordered him to scout a distant mountain range, but the robot refused to leave him. He tried giving him no orders, but the black monster wouldn't stay idle. If no work was assigned, the robot assigned work to himself, suddenly bursting into action and creating havoc in Perceveral's field and sheds.

In self-defense, Perceveral gave him the most harmless task he could think of. He ordered the robot to dig a well, hoping he would bury himself in it. But, grimy and triumphant, the robot emerged every evening and entered the cabin, showering dirt into Perceveral's food, transmitting allergies, and breaking dishes and windows.

Grimly, Perceveral accepted the status quo. The robot now seemed the embodiment of that other, darker side of himself, the inept and accident-prone Perceveral. Watching the robot on his destructive rounds, he felt as though he were watching a misshapen portion of himself, a sickness cast into solid, living form.

He tried to shake free of this fantasy. But more and more the robot came to represent his own destructive urges cut loose from the life impulse and allowed to run rampant.

Perceveral worked, and his neurosis stalked behind him, eternally destructive, yet -- in the manner of neuroses -- protective of itself. His self-perpetuating malady lived with him, watched him while he ate and stayed close while he slept.

Perceveral did his work and became increasingly competent at it. He took what enjoyment he could from the days, regretted the setting of the sun, and lived through the horror of the nights when the robot stood beside his bed and seemed to wonder if now were the time for a summing-up. And in the morning, still alive, Perceveral tried to think of ways of disposing of his staggering, lurching, destructive neurosis.

But the deadlock remained until a new factor appeared to complicate matters.

It had rained heavily for several days. When the weather cleared, Perceveral walked out to his fields. The robot lumbered behind him, carrying the farming tools.

Suddenly a crack appeared in the moist ground under his feet. It widened, and the whole section he was standing on collapsed. Perceveral leaped for firm ground. He made it to the slope, and the robot pulled him up the rest of the way, almost yanking his arm from his socket.

When he examined the collapsed section of field, he saw that a tunnel had run under it. Digging marks were still visible. One side was blocked by the fall. On the other side the tunnel continued deep into the ground.

Perceveral went back for his beamer and his flashlight. He climbed down one side of the hole and flashed his light into the tunnel. He saw a great furry shape retreat hastily around a bend. It looked like a giant mole.

At last he had met another species of life on Theta.

For the next few days he cautiously probed the tunnels. Several times he glimpsed gray molelike shapes, but they fled from him into a labyrinth of passageways.

He changed his tactics. He went only a few hundred feet into the main tunnel and left a gift of fruit. When he returned the next day, the fruit was gone. In its place were two lumps of lead.

The exchange of gifts continued for a week. Then, one day when Perceveral was bringing more fruit and berries, a giant mole appeared, approaching slowly and with evident nervousness. He motioned at Perceveral's flashlight, and Perceveral covered the lens so that it wouldn't hurt the mole's eyes.

He waited. The mole advanced slowly on two legs, his nose wrinkling, his small wrinkled hands clasped to his chest. He stopped and looked at Perceveral with bulging eyes. Then he bent down and scratched a symbol in the dirt of the passageway.

Perceveral had no idea what the symbol meant. But the act itself implied language, intelligence and a grasp of abstractions. He scratched a symbol beside the mole's, to imply the same things.

An act of communication between alien races had begun. The robot stood behind Perceveral, his eye cells glowing, watching while the man and the mole searched for something in common.

Contact meant more labor for Perceveral. The fields and gardens still had to be tended, the repairs on equipment made and the robot watched; in his spare time, Perceveral worked hard to learn the moles' language. And the moles worked equally hard to teach him.

Perceveral and the moles slowly grew to understand each other, to enjoy each other's company, to become friends. Perceveral learned about their daily lives, their abhorrence of the light, their journeys through the underground caverns, their quest for knowledge and enlightenment. And he taught them what he could about Man.

"But what is the metal thing?" the moles wanted to know.

"A servant of Man," Perceveral told them.

"But it stands behind you and glares. It hates you, the metal thing. Do all metal things hate men?"

"Certainly not," Perceveral said. "This is a special case.

"It frightens us. Do all metal things frighten?"

"Some do. Not all."

"And it is hard to think when the metal thing stares at us, hard to understand you. Is it always like that with metal things?"

"Sometimes they do interfere," Perceveral admitted. "But don't worry, the robot won't hurt you."

The mole people weren't so sure. Perceveral made what excuses he could for the heavy, lurching, boorish machine, spoke of machinery's service to Man and the graciousness of life that it made possible. But the mole people weren't convinced and shrank from the robot's dismaying presence.

Nevertheless, after lengthy negotiations, Perceveral made a treaty with the mole people. In return for supplies of fresh fruits and berries, which the moles coveted but could rarely obtain, they agreed to locate metals for future colonists and find sources of water and oil. Furthermore, the colonists were granted possession of all the surface land of Theta and the moles were confirmed in their lordship of the underground.

This seemed an equitable distribution to both parties, and Perceveral and the mole chief signed the stone document with as much of a flourish as an incising tool would allow.

To seal the treaty, Perceveral gave a feast. He and the robot brought a great gift of assorted fruits and berries to the mole people. The gray-furred, soft-eyed moles clustered around, squeaking eagerly to each other.

The robot set down his baskets of fruit and stepped back. He slipped on a patch of smooth rock, flailed for balance, and came crashing down across one of the moles. Immediately he regained his balance and tried, with his clumsy iron hands, to help the mole up. But he had broken the creature's back.

The rest of the moles fled, carrying their dead companion with them. And Perceveral and the robot were left alone in the tunnel, surrounded by great piles of fruit.

That night, Perceveral thought long and hard. He was able to see the damnable logic of the event. Minimum-survival contacts with aliens should have an element of uncertainty, distrust, misunderstanding, and even a few deaths. His dealings with the mole people had gone altogether too smoothly for minimum requirements.

The robot had simply corrected the situation and had performed the errors which Perceveral should have made on his own.

But although he understood the logic of the event, he couldn't accept it. The mole people were his friends and he had betrayed them. There could be no more trust between them, no hope of co-operation for future colonists. Not while the robot clumped and stumbled down the tunnels.

Perceveral decided that the robot must be destroyed. Once and for all, he determined to test his painfully acquired skill against the destructive neurosis that walked continually beside him. And if it cost his life -- well, Perceveral reminded himself, he had been willing to lose it less than a year ago, for much poorer reasons.

He re-established contact with the moles and discussed the problem with them. They agreed to help him, for even these gentle people had the concept of vengeance. They supplied some ideas which were surprisingly human, since the moles also possessed a form of warfare. They explained it to Perceveral and he agreed to try their way.

In a week, the moles were ready. Perceveral loaded the robot with baskets of fruit and led him into the tunnels, as though he were attempting another treaty.

The mole people weren't to be found. Perceveral and the robot journeyed deeper into the passageways, their flashlights probing ahead into the darkness. The robot's eye cells glowed red and he towered close behind Perceveral, almost at his back.

They came to an underground cavern. There was a faint whistle and Perceveral sprinted out of the way.

The robot sensed danger and tried to follow. But he stumbled, thwarted by his own programed ineptness, and fmit scattered across the cavern floor. Then ropes dropped from the blackness of the cavern's roof and settled around the robot's head and shoulders.

He ripped at the tough fiber. More ropes settled around him, hissing in swift flight down from the roof. The robot's eye cells flared as he ripped the cords from his arms.

Mole people emerged from the passageways by the dozens. More lines snaked around the robot, whose joints spurted oil as he strained to break the strands. For minutes, the only sounds in the cavern were the hiss of flying ropes, the creak of the robot's joints, and the dry crack of breaking line.

Perceveral ran back to join the fight. They bound the robot closer and closer until his limbs had no room to gain a purchase. And still the ropes hissed through the air until the robot toppled over, bound in a great cocoon of rope with only his head and feet showing.

Then the mole people squeaked in triumph and tried to gouge out the robot's eyes with their blunt digging claws. But steel shutters slid over the robot's eyes. So they poured sand into his joints until Perceveral pushed them aside and attempted to melt the robot with his last beamer.

The beamer failed before the metal even grew hot. They fastened ropes to the robot's feet and dragged him down a passageway that ended in a deep chasm. They levered him over the side and listened while he bounced off the granite sides of the precipice, and cheered when he struck bottom.

The mole people held a celebration. But Perceveral felt sick. He returned to his shack and lay in bed for two days, telling himself over and over that he had not killed a man, or even a thinking being. He had simply destroyed a dangerous machine.

But he couldn't help remembering the silent companion who had stood with him against the birds, and had weeded his fields and gathered wood for him. Even though the robot had been clumsy and destructive, he had been clumsy and destructive in Perceveral's own personal way -- a way that he, above all people, could understand and sympathize with.

For a while, he felt as though a part of himself had died. But the mole people came to him in the evenings and consoled him, and there was work to be done in the fields and sheds.

It was autumn, time for harvesting and storing his crops. Perceveral went to work. With the robot's removal, his own chronic propensity for accident returned briefly. He fought it back with fresh confidence. By the first snows, his work of storage and food preservation was done. And his year on Theta was coming to an end.

He radioed a full report to Haskell on the planet's risks, promises and potentialities, reported his treaty with the mole people, and recommended the planet for colonization. In two weeks, Haskell radioed back.

"Good work," he told Perceveral. "The Board decided that Theta definitely fits our minimum-survival requirements. We're sending out a colony ship at once."

"Then the test is over?" Perceveral asked.

"Right. The ship should be there in about three months. I'll probably take this batch out. My congratulations, Mr. Perceveral. you're going to be the founding father of a brand-new colony!"

Perceveral said, "Mr. Haskell, I don't know how to thank you -- "

"Nothing to thank me for," Haskell said. "Quite the contrary. By the way, how did you make out with the robot?"

"I destroyed him," Perceveral said. He described the killing of the mole and the subsequent events.

"Hmm," Haskell said.

"You told me there was no rule against it."

"There isn't. The robot was part of your equipment, just like the beamers and tents and food supplies. Like them, he was also part of your survival problems. You had a right to do anything you could about him."

"Then what's wrong?'

"Well, I just hope you really destroyed him. Those quality-control models are built to last, you know. They've got self-repair units and a strong sense of self-preservation. It's damned hard to really knock one out."

"I think I succeeded," Perceveral said.

"I hope so. It would be embarrassing if the robot survived."

"Why? Would it come back for revenge?"

"Certainly not. A robot has no emotions."

"Well?"

"The trouble is this. The robot's purpose was to cancel out any gains you made in survival-quality. It did, in various destructive ways."

"Sure. So, if it comes back, I'll have to go through the whole business again."

"More. You've been separated from the robot for a few months now. If it's still functioning, it's been accumulating a backlog of accidents for you. All the destructive duties that it should have performed during those months -- they'll all have to be discharged before the robot can return to normal duties. See what I mean?"

Perceveral cleared his throat nervously. "And of course he would discharge them as quickly as possible in order to get back to regular operation."

"Of course. Now look, the ship will be there in about three months. That's the quickest we can make it. I suggest you make sure that robot is immobilized. We wouldn't want to lose you now."

"No, we wouldn't," Perceveral said. 'I'll take care of it at once."

He equipped himself and hurried to the tunnels. The mole people guided him to the chasm after he explained the problem. Armed with blowtorch, hacksaw, sledge hammer and cold chisel, Perceveral began a slow descent down the side of the precipice.

At the bottom, he quickly located the spot where the robot had landed. There, wedged between two boulders, was a complete robotic arm, wrenched loose from the shoulder. Further on, he found fragments of a shattered eye cell. And he came across an empty cocoon of ripped and shredded rope.

But the robot wasn't there.

Perceveral climbed back up the precipice, warned the moles and began to make what preparations he could.

Nothing happened for twelve days. Then news was brought to him in the evening by a frightened mole. The robot had appeared again in the tunnels, stalking the dark passageways with a single eye cell glowing, expertly threading the maze into the main branch.

The moles had prepared for his coming with ropes. But the robot had learned. He had avoided the silent dropping nooses and charged into the mole forces. He had killed six moles and sent the rest into flight.

Perceveral nodded briefly at the news, dismissed the mole and continued working. He had set up his defenses in the tunnels. Now he had his four dead beamers disassembled on the table in front of him. Working without a manual, he was trying to interchange parts to produce one usable weapon.

He worked late into the night, testing each component carefully before fitting it back into the casing. The tiny parts seemed to float before his eyes and his fingers felt like sausages. Very carefully, working with tweezers and a magnifying glass, he began reassembling the weapon.

The radio suddenly blared into life.

"Anton?" Haskell asked. "What about the robot?"

"He's coming," said Perceveral.

"I was afraid so. Now listen, I rushed through a priority call to the robot's manufacturers. I had a hell of a fight with them, but I got their permission for you to deactivate the robot, and full instructions on how to do it."

"Thanks," Perceveral said. "Hurry up, how's it done?"

"You'll need the following equipment. A power source of two hundred volts delivered at twenty-five amps. Can your generator handle that?"

"Yes. Go on."

"You'll need a bar of copper, some silver wire and a probe made of some non-conductor such as wood. You set the stuff up in the following -- "

"I'll never have time," Perceveral said, "but tell me quickly."

His radio hummed loudly.

"Haskell!" Perceveral cried.

His radio went dead. Perceveral heard the sounds of breakage coming from the radio shack. Then the robot appeared in the doorway.

The robot's left arm and right eye cell were missing, but his self-repair units had sealed the damaged spots. He was colored a dull black now, with rust-streaks down his chest and flanks.

Perceveral glanced down at the almost-completed beamer. He began fitting the final pieces into place.

The robot walked toward him.

"Go cut firewood," Perceveral said, in as normal a tone as he could manage.

The robot stopped, turned, picked up the ax, hesitated, and started out the door.

Perceveral fitted in the final component, slid the cover into place and began screwing it down.

The robot dropped the ax and turned again, struggling with contradictory commands. Perceveral hoped he might fuse some circuits in the conflict. But the robot made his decision and launched himself at Perceveral.

Perceveral raised the beamer and pressed the trigger. The blast stopped the robot in mid-stride. His metallic skin began to glow a faint red.

Then the beamer failed again.

Perceveral cursed, hefted the heavy weapon and threw it at the robot's remaining eye cell. It just missed, bouncing off his forehead.

Dazed, the robot groped for him. Perceveral dodged his arm and fled from the cabin, toward the black mouth of the tunnel. As he entered, he looked back and saw the robot following.

He walked several hundred yards down the tunnel. Then he turned on a flashlight and waited for the robot.

He had thought the problem out carefully when he'd discovered that the robot had not been destroyed.

His first idea naturally was flight. But the robot, traveling night and day, would easily overtake him. Nor could he dodge aimlessly in and out of the maze of tunnels. He would have to stop and eat, drink and sleep. The robot wouldn't have to stop for anything.

Therefore he had arranged a series of traps in the tunnels and had staked everything on them. One of them was bound to work. He was sure of it.

But even as he told himself this, Perceveral shivered, thinking of the accumulation of accidents that the robot had for him -- the months of broken arms and fractured ribs, wrenched ankles, slashes, cuts, bites, infections and diseases. All of which the robot would hound him into as rapidly as possible, in order to get back to normal routine.

He would never survive the robot's backlog. His traps had to work!

Soon he heard the robot's thundering footsteps. Then the robot appeared, saw him, and lumbered forward.

Perceveral sprinted down a tunnel, then turned into a smaller tunnel. The robot followed, gaining slightly.

When Perceveral reached a distinctive outcropping of rock, he looked back to gauge the robot's position. Then he tugged a cord he had concealed behind the rock.

The roof of the tunnel collapsed, releasing tons of dirt and rock over the robot.

If the robot had continued for another step, he would have been buried. But appraising the situation instantly, he whirled and leaped back. Dirt showered him, and small rocks bounced off his head and shoulders. But the main fall missed him.

When the last pebble had fallen, the robot climbed over the mound of debris and continued the pursuit.

Perceveral was growing short of wind. He was disappointed at the failure of the trap. But, he reminded himself, he had a better one ahead. The next would surely finish off the implacable machine.

They ran down a winding tunnel lit only by occasional flashes from Perceveral's flashlight. The robot began gaining again. Perceveral reached a straight stretch and put on a burst of speed.

He crossed a patch of ground that looked exactly like any other patch. But as the robot thundered over it, the ground gave way. Perceveral had calculated it carefully. The trap, which held under his weight, yielded at once under the robot's bulk.

The robot thrashed for a handhold. Dirt trickled through his fingers and he slid into the trap that Perceveral had dug -- a pit with sloping sides that came together like a great funnel, designed to keep the robot immovably wedged at the bottom.

The robot, however, flung both his legs wide, almost at right angles to his body. His joints creaked as his heels bit into the sloping sides; they sagged under his weight, but held. He was able to stop himself before reaching the bottom, with both legs stiffly outspread and pressed into the soft dirt.

The robot's hand gouged deep handholds in the dirt. One leg retracted and found a foothold; then the other. Slowly the robot extricated himself, and Perceveral started running again.

His breath came short and hard now and he was getting a stitch in his side. The robot gained more easily, and Perceveral had to strain to stay ahead.

He had counted on those two traps. Now there was just one more left. A very good one, but risky to use.

Perceveral forced himself to concentrate in spite of a growing dizziness. The last trap had to be calculated carefully. He passed a stone marked in white and switched off his flashlight. He began counting strides, slowing until the robot was directly behind him, his fingers inches from his neck.

Eighteen-nineteen-twenty!

On the twentieth step, Perceveral flung himself headfirst into the darkness. For seconds, he seemed to be floating in the air. Then he struck water in a flat, shallow dive, surfaced and waited.

The robot had been too close behind to stop. There was a tremendous splash as he hit the surface of the underground lake; a sound of furious splashing; and, finally, the sound of bubbles as the heavy robot sank beneath the surface.

When he heard that, Perceveral struck out for the opposite shore. He made it and pulled himself out of the icy water. For minutes, he lay shuddering on the slimy rocks. Then he forced himself to climb further ashore on hands and knees, to a cache where he had stored firewood, matches, whisky, blankets and clothes.

During the next hours Perceveral dried himself, changed clothes and built a small fire. He ate and drank and watched the still surface of the underground lake. Days ago, he had tested with a hundred-foot line and had found no bottom. Perhaps the lake was bottomless. More likely it fed into a swift-flowing underwater river that would pull the robot along for weeks and months. Perhaps . . .

He heard a faint sound in the water and trained his flashlight in its direction. The robot's head appeared, and then his shoulders and torso emerged.

The lake was very evidently not bottomless. The robot must have walked across the bottom and climbed the steep slope on the opposite side.

The robot began to climb the slimy rocks near shore. Perceveral wearily pulled himself to his feet and broke into a run.

His last trap had failed him and his neurosis was closing in for the kill. Perceveral headed toward a tunnel exit. He wanted the end to come in sunlight.

At a jolting dogtrot, Perceveral led the robot out of the tunnels toward a steep mountain slope. His breath felt like fire in his throat and his stomach muscles were knotted painfully. He ran with his eyes half closed, dizzy from fatigue.

His traps had failed. Why hadn't he realized the certainty of their failure earlier? The robot was part of himself, his own neurosis moving to destroy him. And how can a man trick the trickiest part of himself? The right hand always finds out what the left hand is doing, the cleverest of devices never fools the supreme fooler for long.

He had gone about the thing in the wrong way, Perceveral thought, as he began to climb the mountain slope. The way to freedom is not through deception. It is . . .

The robot clutched at his heel, reminding Perceveral of the difference between theoretical and practical knowledge. Re pulled himself out of the way and bombarded the robot with stones. The robot brushed them aside and continued climbing.

Perceveral cut diagonally across the steep rock face. The way to freedom, he told himself, is not through deception. That was bound to fail. The way out is through change ! The way out is through conquest, not of the robot, but of what the robot represented.

Himself!

He was feeling lightheaded and his thoughts poured on unchecked. If, he insisted to himself, he could conquer his sense of kinship with the robot -- then obviously the robot would no longer be his neurosis! It would simply be a neurosis, with no power over him.

All he had to do was lose his neurosis -- even for ten minutes -- and the robot couldn't harm him!

All sense of fatigue left him and he was flooded with a supreme and intoxicating confidence. Boldly, he ran across a mass of jumbled rocks, a perfect place for a twisted ankle or a broken leg. A year ago, even a month ago, he would infallibly have had an accident. But the changed Perceveral, striding like a demigod, traversed the rocks without error.

The robot, one-armed and one-eyed, doggedly took the accident upon himself. He tripped and sprawled at full length across the sharp rocks. When he picked himself up and resumed the chase, he was limping.

Completely intoxicated but minutely watchful, Perceveral came to a granite wall, and leaped for a fingerhold that was no more than a gray shadow above him. For a heart-stopping second, he dangled in the air. Then, as his fingers began to slip, his foot found a hold. Without hesitation, he pulled himself up.

The robot followed, his dry joints creaking loudly. He bent a finger out of commission making the climb that Perceveral should have failed.

Perceveral leaped from boulder to boulder. The robot came after him, slipping and straining, drawing near. Perceveral didn't care. The thought struck him that all his years of accident-proneness had gone into the making of this moment. The tide had turned now. He was at last what nature had intended him to be all along -- an accident- proof man!

The robot crawled after him up a dazzling surface of white rock. Perceveral, drunk with supreme confidence, pushed boulders into motion and shouted to create an avalanche.

The rocks began to slide, and above him he heard a deep rumble. He dodged around a boulder, evaded the robot's outflung arm and came to a dead end.

He was in a small, shallow cave. The robot loomed in front of him, blocking the entrance, his iron fist pulled back.

Perceveral burst into laughter at the sight of the poor. clumsy, accident-prone robot. Then the robot's fist, driven by the full force of his body, shot out.

Perceveral ducked, but it wasn't necessary. The clumsy robot missed him anyhow, by at least half an inch. It was just the sort of mistake Perceveral had expected of the ridiculous accident-prone creature.

The force of the swing carried the robot outward. He fought hard to regain his balance, poised on the lip of the cliff. Any normal man or robot would have regained it. But not the accident-prone robot. He fell on his face, smashing his last eye cell, and began to roll.

Perceveral leaned out to accelerate the roll, then quickly crouched back inside the shallow cave. The avalanche completed the job for him, rolling a diminishing black dot down the dusty white mountainside and burying it under tons of stone.

Perceveral watched it all, chuckling to himself. Then he began to ask himself what, exactly, he had been doing.

And that was when he started to shake.

Months later, Perceveral stood by the gangplank of the colony ship Cuchulain, watching the colonists step down into Theta's midwinter sunshine. There were all types and kinds.

They had all come to Theta for a chance at a new life. Each of them was vitally important at least to himself, and each deserved a fighting chance at survival, no matter what his potentialities.

And he, Anton Perceveral, had scouted the minimum-survival requirements on Theta for these people; and had, in some measure, given hope and promise to the least capable among them -- the incompetents who also wanted to live.

He turned away from the stream of pioneers and entered the ship by a rear ladder. He walked down a corridor and entered Haskell's cabin.

"Well, Anton," Haskell said, "how do they look to you?"

"They seem like a nice group," Perceveral said.

"They are. Those people consider you their founding father, Anton. They want you here. Will you stay?"

Perceveral said, "I consider Theta my home."

"Then it's settled. I'll just -- "

"Wait," Perceveral said. "I'm not finished. I consider Theta my home. I want to settle here, marry, raise kids. But not yet."

"Eh?"

"I've grown pretty fond of exploring," Perceveral said. "I'd like to do some more of it. Maybe one or two more planets. Then I'll settle down on Theta."

"I was afraid you might want that," Haskell said unhappily.

"What's wrong with it?"

"Nothing. But I'm afraid we can't use you again as an explorer, Anton."

"Why not?"

"You know what we need. Minimum-survival personalities for staking out future colonies. You cannot by any stretch of the imagination be considered a minimum-survival personality any longer."

"But I'm the same man I always was!" Perceveral said. "Oh, sure, I improved on the planet. But you expected that and had the robot to compensate for it. And at the end -- "

"Yes, what about that?"

"Well, at the end I just got carried away. I think I was drunk or something. I can't imagine how I acted that way."

"Still, that's how you did act."

"Yes. But look! Even with that, I barely survived the experience -- the total experience on Theta! Barely! Doesn't that prove I'm still a minimum-survival personality?"

Haskell pursed his lips and looked thoughtful. "Anton, you almost convince me. But I'm afraid you're indulging in a bit of word juggling. In all honesty, I can't view you as minimum any longer. I'm afraid you'll just have to put up with your lot on Theta."

Perceveral's shoulders slumped. He nodded wearily, shook hands with Haskell and turned to go.

As he turned, the edge of his sleeve caught Haskell's inkstand, brushing it off the table. Perceveral lunged to catch it and banged his hand against the desk. Ink splattered over him. He fumbled again, tripped over a chair, fell.

"Anton," Haskell asked, "was that an act?"

"No," Perceveral said. "It wasn't, damn it."

"Hmm. Interesting. Now, Anton, don't raise your hopes too high, but maybe -- I say just maybe -- "

Haskell stared hard at Perceveral's flushed face, then burst into laughter.

"What a devil you are, Anton! You almost had me fooled. Now will you kindly get the hell out of here and join the colonists? They're dedicating a statue to you and I think they'd like to have you present."

Shamefaced, but grinning in spite of it, Anton Perceveral walked out to meet his new destiny.
