"But there are elements which don't like the consequences of genuine libertarianism. And the new science of human behavior, mass and individual, is achieving rigorous formulation. It's becoming the most powerful tool man has ever had--for whoever controls the human mind will also control all that man can do. That science can be used by anyone, mind you. If you'll read between the lines you'll see what a hidden struggle is shaping up for control of it as soon as it reaches maturity and empirical useability."

  "Ah, yes," said the man. "The Psychotechnic Institute."

  Dalgetty nodded, wondering why he had jumped into such a lecture. Well, the more people who had some idea of the truth the better--though it wouldn't do for them to know the whole truth either. Not yet.

  "The Institute trains so many for governmental posts and does so much advisory work," said the man, "that sometimes it looks almost as if it were quietly taking over the whole show."

  Dalgetty shivered a little in the sunset breeze and wished he'd brought his cloak. He thought wearily, Here it is again. Here is the story they are spreading, not in blatant accusations, not all at once, but slowly and subtly, a whisper here, a hint there, a slanted news story, a supposedly dispassionate article.... Oh, yes, they know their applied semantics.

  "Too many people fear such an outcome," he declared. "It just isn't true. The Institute is a private research organization with a Federal grant. Its records are open to anyone."

  "All the records?" The man's face was vague in the gathering twilight.

  Dalgetty thought he could make out a skeptically lifted brow. He didn't reply directly but said, "There's a foggy notion in the public mind that a group equipped with a complete science of man--which the Institute hasn't got by a long shot--could 'take over' at once and, by manipulations of some unspecified but frightfully subtle sort, rule the world. The theory is that if you know just what buttons to push and so on, men will do precisely as you wish without knowing that they're being guided. The theory happens to be pure jetwash."

  "Oh, I don't know," said the man. "In general terms it sounds pretty plausible."

  Dalgetty shook his head. "Suppose I were an engineer," he said, "and suppose I saw an avalanche coming down on me. I might know exactly what to do to stop it--where to plant my dynamite, where to build my concrete wall and so on. Only the knowledge wouldn't help me. I'd have neither the time nor the strength to use it.

  "The situation is similar with regard to human dynamics, both mass and individual. It takes months or years to change a man's convictions and when you have hundreds of millions of men...." He shrugged. "Social currents are too large for all but the slightest, most gradual control. In fact perhaps the most valuable results obtained to date are not those which show what can be done but what cannot."

  "You speak with the voice of authority," said the man.

  "I'm a psychologist," said Dalgetty truthfully enough. He didn't add that he was also a subject, observer and guinea pig in one. "And I'm afraid I talk too much. Go from bad to voice."

  "Ouch," said the man. He leaned his back against the rail and his shadowy hand extended a pack. "Smoke?"

  "No, thanks, I don't."

  "You're a rarity." The brief lighter-flare etched the stranger's face against the dusk.

  "I've found other ways of relaxing."

  "Good for you. By the way I'm a professor myself. English Litt at Colorado."

  "Afraid I'm rather a roughneck in that respect," said Dalgetty. For a moment he had a sense of loss. His thought processes had become too far removed from the ordinary human for him to find much in fiction or poetry. But music, sculpture, painting--there was something else. He looked over the broad glimmering water, at the stations dark against the first stars, and savored the many symmetries and harmonies with a real pleasure. You needed senses like his before you could know what a lovely world this was.

  "I'm on vacation now," said the man. Dalgetty did not reply in kind. After a moment--"You are too, I suppose?"

  Dalgetty felt a slight shock. A personal question from a stranger--well, you didn't expect otherwise from someone like the girl Glenna but a professor should be better conditioned to privacy customs.

  "Yes," he said shortly. "Just visiting."

  "By the way, my name is Tyler, Harmon Tyler."

  "Joe Thomson." Dalgetty shook hands with him.

  "We might continue our conversation if you're going to be around for awhile," said Tyler. "You raised some interesting points."

  Dalgetty considered. It would be worthwhile staying as long as Bancroft did, in the hope of learning some more. "I may be here a couple of days yet," he said.

  "Good," said Tyler. He looked up at the sky. It was beginning to fill with stars. The deck was still empty. It ran around the dim upthrusting bulk of a weather-observation tower which was turned over to its automatics for the night and there was no one else to be seen. A few fluoros cast wan puddles of luminance on the plastic flooring.

  Glancing at his watch, Tyler said casually, "It's about nineteen-thirty hours now. If you don't mind waiting till twenty hundred I can show you something interesting."

  "What's that?"

  "Ah, you'll be surprised." Tyler chuckled. "Not many people know about it. Now, getting back to that point you raised earlier...."

  The half hour passed swiftly. Dalgetty did most of the talking.

  "--and mass action. Look, to a rather crude first approximation a state of semantic equilibrium on a world-wide scale, which of course has never existed, would be represented by an equation of the form--"

  "Excuse me." Tyler consulted the shining dial again. "If you don't mind stopping for a few minutes I'll show you that odd sight I was talking about."

  "Eh? Oh-oh, sure."

  Tyler threw away his cigarette. It was a tiny meteor in the gloom. He took Dalgetty's arm. They walked slowly around the weather tower.

  The men came from the opposite side and met them halfway. Dalgetty had hardly seen them before he felt the sting in his chest.

  A needle gun!

  The world roared about him. He took a step forward, trying to scream, but his throat locked. The deck lifted up and hit him and his mind whirled toward darkness.

  From somewhere will rose within him, trained reflexes worked, he summoned all that was left of his draining strength and fought the anesthetic. His wrestling with it was a groping in fog. Again and again he spiraled into unconsciousness and rose strangling. Dimly, through nightmare, he was aware of being carried. Once someone stopped the group in a corridor and asked what was wrong. The answer seemed to come from immensely far away. "I dunno. He passed out--just like that. We're taking him to a doctor."

  There was a century spent going down some elevator. The boat-house walls trembled liquidly around him. He was carried aboard a large vessel, it was not visible through the gray mist. Some dulled portion of himself thought that this was obviously a private boat-house, since no one was trying to stop--trying to stop--trying to stop....

  Then the night came.

  III

  He woke slowly, with a dry retch, and blinked his eyes open. Noise of air, he was flying, it must have been a triphibian they took him onto. He tried to force recovery but his mind was still too paralyzed.

  "Here. Drink this."

  Dalgetty took the glass and gulped thirstily. It was coolness and steadiness spreading through him. The vibratto within him faded, and the headache dulled enough to be endurable. Slowly he looked around, and felt the first crawl of panic.

  No! He suppressed the emotion with an almost physical thrust. Now was the time for calm and quick wit and--

  A big man near him nodded and stuck his head out the door. "He's okay now, I guess," he called. "Want to talk to him?"

  Dalgetty's eyes roved the compartment. It was a rear cabin in a large airboat, luxuriously furnished with reclining seats and an inlaid table. A broad window looked out on the stairs.

  Caught! It was pure bitterness, an impotent rage at himself. Walked right into their arms!

  Tyler came into the room, followed by a pair of burly stone-faced men. He smiled. "Sorry," he murmured, "but you're playing out of your league, you know."

  "Yeah." Dalgetty shook his head. Wryness twisted his mouth. "I don't league it much either."

  Tyler grinned. It was a sympathetic expression. "You punsters are incurable," he said. "I'm glad you're taking it so well. We don't intend any harm to you."

  Skepticism was dark in Dalgetty but he managed to relax. "How'd you get onto me?" he asked.

  "Oh, various ways. You were pretty clumsy, I'm afraid." Tyler sat down across the table. The guards remained standing. "We were sure the Institute would attempt a counterblow and we've studied it and its personnel thoroughly. You were recognized, Dalgetty--and you're known to be very close to Tighe. So you walked after us without even a face-mask....

  "At any rate, you were noticed hanging around the colony. We checked back on your movements. One of the rec girls had some interesting things to tell of you. We decided you'd better be questioned. I sounded you out as much as a casual acquaintance could and then took you to the rendezvous." Tyler spread his hands. "That's all."

  Dalgetty sighed and his shoulders slumped under a sudden enormous burden of discouragement. Yes, they were right. He was out of his orbit. "Well," he said, "what now?"

  "Now we have you and Tighe," said the other. He took out a cigarette. "I hope you're somewhat more willing to talk than he is."

  "Suppose I'm not?"

  "Understand this." Tyler frowned. "There are reasons for going slow with Tighe. He has hostage value, for one thing. But you're nobody. And while we aren't monsters I for one have little sympathy to spare for your kind of fanatic."

  "Now there," said Dalgetty with a lift of sardonicism, "is an interesting example of semantic evolution. This being, on the whole, an easy-going tolerant period, the word 'fanatic' has come to be simply an epithet--a fellow on the other side."

  "That will do," snapped Tyler. "You won't be allowed to stall. There are questions we want answered." He ticked the points off on his fingers. "What are the Institute's ultimate aims? How is it going about attaining them? How far has it gotten? Precisely what has it learned, in a scientific way, that it hasn't published? How much does it know about us?" He smiled thinly. "You've always been close to Tighe. He raised you, didn't he? You should know just as much as he."

  Yes, thought Dalgetty, Tighe raised me. He was all the father I ever had, really. I was an orphan and he took me in and he was good.

  Sharp in his mind rose the image of the old house. It had lain on broad wooded grounds in the fair hills of Maine, with a little river running down to a bay winged with sailboats. There had been neighbors--quiet-spoken folk with something more real about them than most of today's rootless world knew. And there had been many visitors--men and women with minds like flickering sword-blades.

  He had grown up among intellects aimed at the future. He and Tighe had traveled a lot. They had often been in the huge pylon of the main Institute building. They had gone over to Tighe's native England once a year at least. But always the old house had been dear to them.

  It stood on a ridge, long and low and weathered gray like a part of the earth. By day it had rested in a green sun-dazzle of trees or a glistering purity of snow. By night you heard the boards creaking and the lonesome sound of wind talking down the chimney. Yes, it had been good.

  And there had been the wonder of it. He loved his training. The horizonless world within himself was a glorious thing to explore. And that had oriented him outward to the real world--he had felt wind and rain and sunlight, the pride of high buildings and the surge of a galloping horse, thresh of waves and laughter of women and smooth mysterious purr of great machines, with a fullness that made him pity those deaf and dumb and blind around him.

  Oh yes, he loved those things. He was in love with the whole turning planet and the big skies overhead. It was a world of light and strength and swift winds and it would be bitter to leave it. But Tighe was locked in darkness.

  He said slowly, "All we ever were was a research and educational center, a sort of informal university specializing in the scientific study of man. We're not any kind of political organization. You'd be surprised how much we differ in our individual opinions."

  "What of it?" shrugged Tyler. "This is something larger than politics. Your work, if fully developed, would change our whole society, perhaps the whole nature of man. We know you've learned more things than you've made public. Therefore you're reserving that information for uses of your own."

  "And you want it for your purposes?"

  "Yes," said Tyler. After a moment, "I despise melodrama but if you don't cooperate you're going to get the works. And we've got Tighe too, never forget that. One of you ought to break down if he watches the other being questioned."

  We're going to the same place! We're going to Tighe!

  The effort to hold face and voice steady was monstrous. "Just where are we bound?"

  "An island. We should be there soon. I'll be going back again myself but Mr. Bancroft is coming shortly. That should convince you just how important this is to us."

  Dalgetty nodded. "Can I think it over for awhile? It isn't an easy decision for me."

  "Sure. I hope you decide right."

  Tyler got up and left with his guards. The big man who had handed him the drink earlier sat where he had been all the time. Slowly the psychologist began to tighten himself. The faint drone of turbines and whistle of jets and sundered air began to enlarge.

  "Where are we going?" he asked.

  "CAN'T TELL YOU THAT. SHUDDUP, WILL YOU?"

  "But surely...."

  The guard didn't answer. But he was thinking. Ree-villa-ghee-gay-doe--never would p'rnounce that damn Spig name ... cripes, what a God-forsaken hole!... Mebbe I can work a trip over to Mexico.... That little gal in Guada....

  Dalgetty concentrated. Revilla--he had it now. Islas de Revillagigedo a small group some 350 or 400 miles off the Mexican coast, little visited with very few inhabitants. His eidetic memory went to work, conjuring an image of a large-scale map he had once studied. Closing his eyes he laid off the exact distance, latitude and longitude, individual islands.

  Wait, there was one a little further west, a speck on the map, not properly belonging to the group. And--he riffled through all the facts he had ever learned pertaining to Bancroft. Wait now, Bertrand Meade, who seemed to be the kingpin of the whole movement--yes, Meade owned that tiny island.

  So that's where we're going! He sank back, letting weariness overrun him. It would be awhile yet before they arrived.

  Dalgetty sighed and looked out at the stars. Why had men arranged such clumsy constellations when the total pattern of the sky was a big and lovely harmony? He knew his personal danger would be enormous once he was on the ground. Torture, mutilation, even death.

  Dalgetty closed his eyes again. Almost at once he was asleep.

  IV

  They landed on a small field while it was still dark. Hustled out into a glare of lights Dalgetty did not have much chance to study his surroundings. There were men standing on guard with magnum rifles, tough-looking professional goons in loose gray uniforms. Dalgetty followed obediently across the concrete, along a walk and through a garden to the looming curved bulk of a house.

  He paused just a second as the door opened for them and stood looking out into darkness. The sea rolled and hissed there on a wide beach. He caught the clean salt smell of it and filled his lungs. It might be the last time he ever breathed such air.

  "Get along with you." An arm jerked him into motion again.

  Down a bare coldly-lit hallway, down an escalator, into the guts of the island. Another door, a room beyond it, an ungentle shove. The door clashed to behind him.

  Dalgetty looked around. The cell was small, bleakly furnished with bunk, toilet and washstand, had a ventilator grille in one wall. Nothing else. He tried listening with maximum sensitivity but there were only remote confused murmurs.

  Dad! he thought. You're here somewhere too.

  He flopped on the bunk and spent a moment analyzing the aesthetics of the layout. It had a certain pleasing severity, the unconscious balance of complete functionalism. Soon Dalgetty went back to sleep.

  A guard with a breakfast tray woke him. Dalgetty tried to read the man's thoughts but there weren't any to speak of. He ate ravenously under a gun muzzle, gave the tray back and returned to sleep. It was the same at lunch time.

  His time-sense told him that it was 1435 hours when he was roused again. There were three men this time, husky specimens. "Come on," said one of them. "Never saw such a guy for pounding his ear."

  Dalgetty stood up, running a hand through his hair. The red bristles were scratchy on his palm. It was a cover-up, a substitute symbol to bring his nervous system back under full control. The process felt as if he were being tumbled through a huge gulf.

  "Just how many of your fellows are there here?" he asked.

  "Enough. Now get going!"

  He caught the whisper of thought--fifty of us guards, is it? Yeah, fifty, I guess.

  Fifty! Dalgetty felt taut as he walked out between two of them. Fifty goons. And they were trained, he knew that. The Institute had learned that Bertrand Meade's private army was well-drilled. Nothing obtrusive about it--officially they were only servants and bodyguards--but they knew how to shoot.

  And he was alone in mid-ocean with them. He was alone and no one knew where he was and anything could be done to him. He felt cold, walking down the corridor.

  There was a room beyond with benches and a desk. One of the guards gestured to a chair at one end. "Sit," he grunted.

  Dalgetty submitted. The straps went around his wrists and ankles, holding him to the arms and legs of the heavy chair. Another buckled about his waist. He looked down and saw that the chair was bolted to the floor. One of the guards crossed to the desk and started up a tape recorder.
