“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.”
He paused to light a cigarette. “If you feel ill, young man, there’s drinking water in that bottle. You look ill.”
“I’m all right!”
“Well, to continue: The intelligent animal became master of his planet. Threats to his existence were overcome—unless he was a threat to himself, like we are. But now, the parasites had found a safe home. No new threats to force readaption. They sat back and sighed and became stagnant—as unchanging as horseshoe crabs or amoeba or other Earth ancients. They kept right on working in their neurological beehives, and now they became cultivated by the animal, who recognized their benefactors. They didn’t know it, but they were no longer the dominant species. They had insured their survival by leaning on their animal prop, who now took care of them with godlike charity—and selfishness. The parasites had achieved biological heaven. They kept on working, but they stopped fighting. The host was their welfare state, you might say. End of a sequence.”
He blew a long breath of smoke and leaned forward to watch Paul, with casual amusement. Paul suddenly realized that he was sitting on the edge of his chair and gaping. He forced a relaxation.
“Wild guesswork,” he breathed uncertainly.
“Some of it’s guesswork,” Seevers admitted. “But none of it’s wild. There is supporting evidence. It’s in the form of a message.”
“Message?”
