The traveler was shocked at the words. He hadn't intended them to come out that way. Somehow Mersey had voiced the underlying thoughts of his people. The traveler sought the doctor's reaction, but Mersey wouldn't look at him. The man's gaze was fixed on the ceiling above the couch.

"Of course," the doctor said. His words were false, the visitor realized; he was humoring the madman.

"We had so much, but now there is no future," Mersey said. The visitor tried to stop him. He would not be stopped. "We can't stay much longer. We'll die. We must find a new world. Maybe you can help us."

Dr. Cloyd spoke and there was no hint of surprise in his voice.

"I'll help you all I can. Would you care to tell me more about your world?"

Desperately, the visitor fought to control the flow of Mersey's words.

He had opened the gate to the other world--how, he did not know--and all of his knowledge and memories now were Mersey's. But the traveler could not communicate with the disordered mind. He could only communicate through it, and then involuntarily. If he could escape the mind ... but he could not escape. Mersey's eyes were fixed on the ceiling. He would not look at the doctor.

"A dying world," Mersey said. "It will live on after us, but we will die because we have finished. There's nothing more to do. The Change is upon us, and we must flee it or die. I have been sent here as a last hope, as an emissary to learn if this world is the answer. I have traveled among you and I have found good things. Your world is much like ours, physically, but it has not grown as fast or as far as ours, and we would be happy here, among you, if we could control."

The words from Mersey's throat had come falteringly at first, but now they were strong, although the tone was flat and expressionless. The words went on:

"But we can't control. I've tried and failed. At best we can co-exist, as observers and vicarious partic.i.p.ants, but we must surrender choice.

Is that to be our destiny--to live on, but to be denied all except contemplation--to live on as guests among you, accepting your ways and sharing them, but with no power to change them?"

The traveler shouted at Mersey's mind in soundless fury: "Shut up!

Shut up!"

Mersey stopped talking.

"Go on," said the doctor softly. "This is very interesting."

"Shut up!" said the traveler voicelessly, yet with frantic urgency.

The madman was silent. His body was perfectly still, except for his calm breathing. The visitor gazed through his eyes in the only possible direction--up at the ceiling. He tried another command. "Look at the doctor."

With that glance, the visitor told himself, he would flee the crazed mind and enter the doctor's. There he would learn what the psychiatrist thought of his patient's strange soliloquy--whether he believed it, or any part of it.

He prayed that the doctor was evaluating it as the intricate raving of delusion.

Slowly, Mersey turned his head. Through his eyes, the visitor saw the faded green carpet, the doctor's dull-black shoes, his socks, the legs of his trousers. Mersey's glance hovered there, around the doctor's knees. The visitor forced it higher, past the belt around a tidy waist, along the b.u.t.tons of the opened vest to the white collar, and finally to the kindly eyes behind gold-rimmed gla.s.ses.

Again he had commanded this human being and had been obeyed. The traveler braced himself for the leap from the tortured mind to the sane one.

But his gaze continued to be that of Mersey.

The gray eyes of the doctor were on his patient. Intelligence and kindness were in those eyes, but the visitor could read nothing else.

He was caught, a prisoner in a demented mind. He felt panic. This must be the mind-screen he'd been warned about.

"Look down," the visitor commanded Mersey. "Shut your eyes. Don't let him see me."

But Mersey continued to be held by the doctor's eyes. The visitor cowered back into the crazed mental tangle.

Gradually, then, his fear ebbed. There was more likelihood that Cloyd did not believe Mersey's words than that he did. The doctor treated hundreds of patients and surely many of them had delusions as fanciful as this one might seem.

The traveler's alarm simmered down until he was capable of appreciating the irony of the situation.

But at the same time, he thought with pain, "Is it our fate that of all the millions of creatures on this world, we can establish communication only through the insane? And even then to have only imperfect control of the mind and, worse, to have it become a transmitter for our most secret thoughts?"

It was heartbreaking.

Dr. Cloyd broke the long silence. Pulling at his ear, he spoke calmly and matter-of-factly:

"Let me see if I understand your problem, Mersey. You believe yourself to be from another world, from which you have traveled, although not physically. Your world is not a material one, as far as its people are concerned. Your civilization is a mental one, which has been placed in danger. You must resettle your people, but this cannot be done here, on Earth, except in the minds of the mentally ill--and that would not be a satisfactory solution. Have I stated the case correctly?"

"Yes," Mersey's voice said over the traveler's mental protests.

"Except that it is not a 'case,' as you call it. I am not Mersey. He is merely a vehicle for my thoughts. I am not here to be treated or cured, as the human being Mersey is. I'm here with a life-or-death problem affecting an entire race, and I would not be talking to you except that, at the moment, I'm trapped and confused."

The madman was doing it again, the traveler thought helplessly--spilling out his knowledge, betraying him and his kind.

Was there no way to m.u.f.fle him?

"I must admit that I'm confused myself," Dr. Cloyd said. "Humor me for a moment while I think out loud. Let me consider this in my own framework, first, and then in yours, without labeling either one absolutely true or false.

"You see," the doctor went on, "this is a world of vitality. My world--Earth. Its people are strong. Their bodies are developed as well as their minds. There are some who are not so strong, and some whose minds have been injured. But for the most part, both the mind and the body are in balance. Each has its function, and they work together as a coordinated whole. My understanding of your world, on the other hand, is that it's in a state of imbalance, where the physical has deteriorated almost to extinction and the mind has been nurtured in a hothouse atmosphere. Where, you might say, the mind has fed on the decay of the body."

"No," said Mersey, voicing the traveler's conviction. "You paint a highly distorted picture of our world."

"I theorize, of course," Dr. Cloyd agreed. "But it's a valid theory, based on intimate knowledge of my own world and what you've told me of yours."

"You make a basic error, I think," Mersey said, speaking for the unwilling visitor. "You a.s.sume that I have been able to make contact only with this deranged mind. That is wrong. I have shared the experiences of many of you--a man, a boy, a woman about to bear a child. Even a cat. And with each of these, my mind has been perfectly attuned. I was able to share and enjoy their experiences, their pleasures, to love with them and to fear, although they had no knowledge of my presence.

[Ill.u.s.tration]

"Only since I came to this poor mind have I failed to achieve true empathy. I have been shocked by his madness and I've tried to resist it, to help him overcome it. But I've failed and it apparently has imprisoned me. Whereas I was able to leave the minds of the others almost at will, with poor Mersey I'm trapped. I can't transfer to you, for instance, as I could normally from another. If there's a way out, I haven't found it. Have you a theory for this?"

In spite of his distress at these revelations, the traveler was intrigued, now that they had been voiced for him, and he was eager to hear Dr. Cloyd's interpretation of them.

The psychiatrist took a pipe out of his pocket, filled it, lighted it and puffed slowly on it until it was drawing well.

"Continuing to accept your postulate that you're not Mersey, but an alien inhabiting his mind," the doctor said finally, "I can enlarge on my theory without changing it in any basic way.

"Your world is not superior to ours, much as it may please you to believe that it is. Nature consists of a balance, and that balance must hold true whether in Sioux City, or Mars, or in the fourth dimension, or in your world, wherever that may be. Your world is out of balance. Evidently it has been going out of balance for some time.

"Your salvation lies not in further evolution in your world--since your way of evolving proved wrong, and may prove fatal--but in a change in course, back along the evolutionary path to a society which developed naturally, with the mind and the body in balance. That society is the one you have found here, in our world. You found it pleasant and attractive, you say, but that doesn't mean you're suited to it.

"Nature's harsh rules may have operated to let you observe a way of life here that you enjoy, but to exclude you otherwise--except from a mind that is not well. In nature's balance, it could be that the refuge on this world most closely resembling your needs is in the mind of the psychotic. One conclusion could be that your race is mentally ill--by our standards, if not by yours--and that the type of person here most closely approximating your way of life is one with a disordered mind."
