A yacht. The open sea. A semitropical island, uninhabited, on the brink of the Caribbean. And a woman, of course—chosen from among the many who would be willing to share such an escape. Peculiarly, he glanced at Willie's door. It was too bad about her. But she'd get along okay. The yacht . . . if he were only certain of Mendelhaus' intentions ...
The priest began frowning at Paul's hesitation. "Well?" "I don't want to put you to any trouble. . . ."
"Nonsense! You're still afraid of us! Very well, come with me. There's someone I want you to see." Mendelhaus turned and started down the corridor.
Paul lingered. "Who . . . what—"
"
Come on!" the priest snapped impatiently.
Reluctantly, Paul followed him to the stairway. They descended to a gloomy basement and entered a smelly laboratory through a double-door. Electric illumination startled him; then he heard the sound of a gasoline engine and knew that the power was generated locally.
"Germicidal lamps," murmured the priest, following his ceilingward gaze. "Some of them are. Don't worry about touching things. It's sterile in here."
"But it's not sterile for your convenience," growled an invisible voice. "And it won't be sterile at all if you don't stay out! Beat it, preacher!"
Paul looked for the source of the voice, and saw a small, short-necked man bending his shaggy gray head over a microscope at the other end of the lab. He had spoken without glancing up at his visitors.
"
This is Doctor Seevers, of Princeton, son," said the priest, unruffled by the scientist's ire. "Claims he's an atheist, but personally I think he's a puritan. Doctor, this is the young man I was telling you about. Will you tell him what you know about neuroderm?"
Seevers jotted something on a pad, but kept his eye to the instrument. "Why don't we just give it to him, and let him find out for himself?" the scientist grumbled sadistically.
"Don't frighten him, you heretic! I brought him here to be illuminated."
"
Illuminate him yourself. I'm busy. And stop calling me names. I'm not an atheist; I'm a biochemist."
"
Yesterday you were a biophysicist. Now, entertain my young man." Mendelhaus blocked the doorway with his body. Paul, with his jaw clenched angrily, had turned to leave.
"
That's all I can do, preacher," Seevers grunted. "Entertain him. I know nothing. Absolutely nothing. I have some observed data. I have noticed some correlations. I have seen things happen. I have traced the patterns of the happenings and found some probable common denominators. And that is all! I admit it. Why don't you preachers admit it in your racket?"
"Seevers, as you can see, is inordinately proud of his humility—if that's not a paradox," the priest said to Paul.
"
Now, Doctor, this young man—"
Seevers heaved a resigned sigh. His voice went sour-sweet. "All right, sit down, young man. I'll entertain you as soon as I get through counting free nerve-endings in this piece of skin."
Mendelhaus winked at his guest. "Seevers calls it masochism when we observe a fast-day or do penance. And there he sits, ripping off patches of his own hide to look at through his peeping glass. Masochism—heh!"
"Get out, preacher!" the scientist bellowed.
Mendelhaus laughed mockingly, nodded Paul toward a chair, and left the lab. Paul sat uneasily watching the back of Seevers' lab jacket.
"Nice bunch of people really—these black-frocked yahoos," Seevers murmured conversationally. "If they'd just stop trying to convert me."
"Doctor Seevers, maybe I'd better—"
"Quiet! You bother me. And sit still, I can't stand to have people running in and out of here. You're in; now stay in."
Paul fell silent. He was uncertain whether or not Seevers was a dermie. The small man's lab jacket bunched up to hide the back of his neck, and the sleeves covered his arms. His hands were rubber-gloved, and a knot of white cord behind his head told Paul that he was wearing a gauze mask. His ears were bright pink, but their color was meaningless; it took several months for the gray coloring to seep to all areas of the skin. But Paul guessed he was a dermie—and wearing the gloves and mask to keep his equipment sterile.
He glanced idly around the large room. There were several glass cages of rats against the wall. They seemed airtight, with ducts for forced ventilation. About half the rats were afflicted with neuroderm in its various stages. A few wore shaved patches of skin where the disease had been freshly and forcibly inflicted. Paul caught the fleeting impression that several of the animals were staring at him fixedly. He shuddered and looked away.
He glanced casually at the usual maze of laboratory glassware, then turned his attention to a pair of hemispheres, suspended like a trophy on the wall. He recognized them as the twin halves of one of the meteorites, with the small jelly-pocket in the center. Beyond it hung a large picture frame containing several typewritten sheets. Another frame held four pictures of bearded scientists from another century, obviously clipped from magazine or textbook. There was nothing spectacular about the lab. It smelled of clean dust and sour things. Just a small respectable workshop.
Seevers' chair creaked suddenly. "It checks," he said to himself. "It checks again. Forty per cent increase." He threw down the stub pencil and whirled suddenly. Paul saw a pudgy round face with glittering eyes. A dark splotch of neuroderm had crept up from the chin to split his mouth and cover one cheek and an eye, giving him the appearance of a black and white bulldog with a mixed color muzzle.
"It checks," he barked at Paul, then smirked contentedly.
"What checks?"
The scientist rolled up a sleeve to display a patch of adhesive tape on a portion of his arm which had been discolored by the disease. "Here," he grunted. "Two weeks ago this area was normal. I took a centimeter of skin from right next to this one, and counted the nerve endings. Since that time, the derm's crept down over the area. I took another square centimeter today, and recounted. Forty per cent increase."
Paul frowned with disbelief. It was generally known that neuroderm had a sensitizing effect, but new nerve endings . . . No. He didn't believe it.
"Third time I've checked it," Seevers said happily. "One place ran up to sixty-five per cent. Heh! Smart little bugs, aren't they? Inventing new somesthetic receptors that way!"
Paul swallowed with difficulty. "What did you say?" he gasped.
Seevers inspected him serenely. "So you're a non-hyper, are you? Yes, indeed, I can smell that you are. Vile, really. Can't understand why sensible hypers would want to paw you. But then, I've insured myself against such foolishness."
He said it so casually that Paul blinked before he caught the full impact of it. "Y-y-you've done what?"
"
What I said. When I first caught it, I simply sat down with a velvet-tipped stylus and located the spots on my hands that gave rise to pleasurable sensations. Then I burned them out with an electric needle. There aren't many of them, really—one or two points per square centimeter." He tugged off his gloves and exhibited pick-marked palms to prove it. "I didn't want to be bothered with such silly urges. Waste of time, chasing nonhypers, for me it is. I never learned what it's like, so I've never missed it." He turned his hands over and stared at them. "Stubborn little critters keep growing new ones, and I keep burning them out."
Paul leaped to his feet. "Are you trying to tell me that the plague causes new nerve cells to grow?"
Seevers looked up coldly. "Ah, yes. You came here to be illooominated, as the padre put it. If you wish to be de-idiotized, please stop shouting. Otherwise, I'll ask you to leave."
Paul, who had felt like leaving a moment ago, now sub-sided quickly. "I'm sorry," he snapped, then softened his tone to repeat: "I'm sorry."
Seevers took a deep breath, stretched his short meaty arms in an unexpected yawn, then relaxed and grinned. "Sit down, sit down, m'boy. I'll tell you what you want to know, if you really want to know anything. Do you?"
"Of course!"
"You don't! You just want to know how you—whatever your name is—will be affected by events. You don't care about understanding for its own sake. Few people do. That's why we're in this mess. The padre now, he cares about understanding events—but not for their own sake. He cares, but for his flock's sake and for his God's sake—which is, I must admit, a better attitude than that of the common herd, whose only interest is in their own safety. But if people would just want to understand events for the understanding's sake, we wouldn't be in such a pickle."
Paul watched the professor's bright eyes and took the lecture quietly.
"
And so, before I illuminate you, I want to make an impossible request."
"Yes, sir."
"I ask you to be completely objective," Seevers continued, rubbing the bridge of his nose and covering his eyes with his hand. "I want you to forget you ever heard of neuroderm while you listen to me. Rid yourself of all preconceptions, especially those connected with fear. Pretend these are purely hypothetical events that I'm going to discuss." He took his hands down from his eyes and grinned sheepishly. "It always embarrasses me to ask for that kind of cooperation when I know damn well I'll never get it."
"I'll try to be objective, sir."
"
Bah!" Seevers slid down to sit on his spine, and hooked the base of his skull over the back of the chair. He blinked thoughtfully at the ceiling for a moment, then folded his hands across his small paunch and closed his eyes.
When he spoke again, he was speaking to himself: "Assume a planet, somewhat earthlike, but not quite. It has carboniferous life forms, but not human. Warm blooded, probably, and semi-intelligent. And the planet has something else—it has an overabundance of parasite forms. Actually, the various types of parasites are the dominant species. The warm blooded animals are the parasites' vegetables, so to speak. Now, during two billion years, say, of survival contests between parasite species, some parasites are quite likely to develop some curious methods of adaption. Methods of insuring the food supply—animals, who must have been taking a beating."
Seevers glanced down from the ceiling. "Tell me, youngster, what major activity did Man invent to secure his vegetable food supply?"
"Agriculture?"
"
Certainly. Man is a parasite, as far as vegetables are concerned. But he learned to eat his cake and have it, too. He learned to perpetuate the species he was devouring. A very remarkable idea, if you stop to think about it. Very!"
"I don't see—"
"Hush! Now, let's suppose that one species of micro-parasites on our hypothetical planet learned, through long evolutionary processes, to stimulate regrowth in the animal tissue they devoured. Through exuding controlled amounts of growth hormone, I think. Quite an advancement, eh?"
Paul had begun leaning forward tensely.
"But it's only the first step. It let the host live longer, although not pleasantly, I imagine. The growth control would be clumsy at first. But soon, all parasite-species either learned to do it, or died out. Then came the contest for the best kind of control. The parasites who kept their hosts in the best physical condition naturally did a better job of survival—since the parasite-ascendancy had cut down on the food supply, just as Man wastes his own resources. And since animals were contending among themselves for a place in the sun, it was to the parasite's advantage to help insure the survival of his host-species —through growth control."
Seevers winked solemnly. "Now begins the downfall of the parasites—their decadence. They concentrated all their efforts along the lines of . . . uh . . . scientific farming, you might say. They began growing various sorts of defense and attack weapons for their hosts—weird biodevices, perhaps. Horns, swords, fangs, stingers, poisonthrowers—we can only guess. But eventually, one group of parasites hit upon—what?"
Paul, who was beginning to stir uneasily, could only stammer. Where was Seevers getting all this?
"Say it!" the scientist demanded.
"The ... nervous system?"
"That's right. You don't need to whisper it. The nervous system. It was probably an unsuccessful parasite at first, because nerve tissue grows slowly. And it's a long stretch of evolution between a microspecies which could stimulate nerve growth and one which could direct and utilize that growth for the host's advantage—and for its own. But at last, after a long struggle, our little species gets there. It begins sharpening the host's senses, building up complex senses from aggregates of old style receptors, and increasing the host's intelligence within limits."
Seevers grinned mischievously. "Comes a planetary shake-up of the first magnitude. Such parasites would naturally pick the host species with the highest intelligence to begin with. With the extra boost, this brainy animal quickly beats down its own enemies, and consequently the enemies of its microbenefactor. It puts itself in much the same position that Man's in on Earth—lord it over the beasts, divine right to run the place, and all that. Now understand—it's the animal who's become intelligent, not the parasites. The parasites are operating on complex instinct patterns, like a hive of bees. They're wonderful neurological engineers—like bees are good structural engineers; blind instinct, accumulated through evolution."
