Chapter 2

Inside, the cabin in the sky seemed to be built almost entirely around a huge primeval looking fireplace. Despite the fierceness of the Arizona sun there was a fire in it of long and bluish flames, one of those modern inventions which reverse the processes of nature. Like the gas refrigerators of an older period, this fire worked in combination with the airconditioning system to cool the house, lending to it in the midst of summer heat the same attractions which it had in winter.

In front of the fire and framed by its rather ghostly light, there stood a man with his head bowed down, pensively staring at the flames. As Lee’s steps resounded from the ancient millstones which formed the floor, Dr. Scriven wheeled around; he approached the man from Down-Under with outstretched hands.

Rarely had Lee seen such a distinguished looking figure of a man. He looked more like a diplomat of the extinct old school than a scientist, with the immaculate expanse of his white tropical suit and the dignity of his leonine head. His width of shoulder and the smooth agility with which he moved gave the impression of great strength. Only his fingers were small, slender, almost like a woman’s.

The reluctant softness of their pressure contrasted so much with his heartiness of manner that Lee felt repulsed by their touch until he remembered that a great surgeon lived and caused others to live by his sensitivity of hand.

“Dr. Lee, I’m happy, most happy, that you have been able to come.” Scriven’s voice was soft, but he spoke with an extraordinary precision of diction which had a quality almost of command. “Over there, please, by the fire...”

From the blue flames there came the freshness and the coolness of an ocean breeze; the rawhide chairs, built for barbaric chieftains as they seemed, proved to be most comfortable; the semidarkness, the roughness of the unhewn stone, gave a sense of the phantastical and the paradox. Lee sat and waited patiently for Scriven to explain.

“In case you’re wondering a little about this setup,” Scriven made a sweeping gesture around the room, “I’ve long since reached the conclusion that in these mad times a man needs above all some padded cell, some shell in which to retire and preserve his sanity. This is my padded cell, soundproof, lightproof, telephoneproof; a wholesome reminder of the basic, the primeval things. Simple, isn’t it?”

Lee blinked at the extravagance of this statement. “Do you really call that simple?” he asked.

Scriven grinned: “You are right; it is of course a willed reversal from the complex, synthetic and perhaps a little perverse. But then, not everybody has the opportunity you had in living in the heart of nature. Frankly I envy you; your work reflects the depth of thinking which comes out of retirement from the world. That’s why I called you here; that’s why I am so sure you’ll understand.”

He paused. Lee thought that he saw what was perhaps a mannerism; the great surgeon didn’t look at his visitor. With his head turned aside, staring into the flames, stroking his chin, speaking as if to himself, he reminded Lee of some medieval alchemist.

“It’s a long story, Lee,” Scriven continued. “It starts way back with a letter I wrote to the President of the United States. In this letter I pointed to the immense dangers which I anticipated in the event of an atom war; dangers to which the military appeared to be blind. I am referring to the inadequacy of the human brain and its susceptibility to mental and psychic shock. I explained how science and technology over the past few hundred years had developed by the pooled efforts of the elite in human brains, but that the individual brain, even if outstanding, was lagging farther and farther below the dizzy peak which science and technology in their totality had reached. I further explained, by the example of the Nazi and Jap States, how the collective brains of modern masses are reverting from and are hostile to a high level of civilization because it is beyond their mental reach. You know all this, of course, Lee. I made it clear that not even the collective brains of a general staff could be relied upon for normal functioning; that no matter how carefully protected physically, they remained exposed to psychic shock with its resultant errors of judgment. How much less then could production and transportation workers be expected to function effectively in the apocalyptic horrors they would have to face...”

Lee’s eyes had narrowed in the concentration of listening; his head nodded approval. He wasn’t conscious of it, but Scriven took note of it by a quick glance. His voice quickened:

“That was the first part of my letter, Lee. I then came out squarely with the project which has since become the work of my life. I told the President that under these circumstances the most needed thing for our country’s national security would be the creation of a mechanical brain, some central ganglion bigger and better than its human counterpart, immune to shock of any kind. This ganglion to be established in the innermost fortress of America as an auxiliary augmenting and controlling the work of a general staff. I gave him a fairly detailed outline of just how the thing could be done. There was really nothing basically new involved. Personally I have held for a long time that Man never “invents”, that in fact it is constitutionally impossible for him to do so. Being a part of nature Man merely discovers what nature has “invented” in some form of its own a long time ago. Mechanical brains. Lord, we have had them in their rudiments for the past hundred thousand years, at a minimum. The calendar is one; every printed book is one; the simplest of machines incorporates one. And ever since the first mechanical clock started its ticking we have developed them by leaps and bounds!”

“And did the President react positively to this project?” Lee asked.

Scriven shook his head. “He did not.”

Then he paused. Little beads of perspiration had appeared on his forehead; he wiped them away with a handkerchief:

“That year, Lee,” he began again, “when the decision was pending and I could do nothing but wait, knowing that there was no other defense against the Atom Bomb, knowing that our country’s fate was at stake--it made me grey, it came pretty close to shattering my nerve ... But then...” His body tightened, the small fist pounded the rail of the chair: “... But then We BUILT THE BRAIN.“

He said it almost in a triumphant cry.

Mounting tension had Lee almost frozen to his seat. Now he stirred and leaned forward.

“It actually exists? I mean it works? It is not limited to the analysis of mathematical problems but capable of cerebrations after the manner of the human brain?”

Scriven, with a startling change, sounded dry, very factual in a tired way as he answered: “I appreciate your difficulty of realization, Dr. Lee. The whole idea is new to you and I have presented it in a rather abrupt and inadequate way. In time, and if we get together, as I hope we will, you shall get visual impressions which are better than words. For the moment, just to give you a general idea and to prove that this is not a small matter, let me give you a few facts: Our first monetary appropriation for The Brain, as an unspecified part of the military budget, of course, was for one billion dollars. We have since received two more appropriations of an equal size.”

Lee’s gasp made a sound like a low whistle. With a depreciating gesture Scriven waved it away.

“While these funds could only cover the first stages in the construction of The Brain,” he calmly went on, “we have been able to build a mechanical cortex mantle composed of ninety billion electronic cells. Considering that the cortex mantle of the human brain contains over 9 billion cells, this doesn’t sound like much. Our synthetic or mechanical cells are a little better than the organic, natural cells, but not very much. So alone and by themselves their number would indicate only a ten times superiority of The Brain over its human counterpart. If that were all the result of our labors, a brain of, let’s say, twice genius capacity, we would be a miserable failure. But then we have achieved a very considerable improvement in the utilization of the The Brain’s cortex capacity. In the first place we have full control over the intake of thought impulses; and more important, we use multiple wave lengths in feeding impulses to The Brain and throughout all the impulse-processings. Even the human brain has some capacity of simultaneous thought on different levels of consciousness, but its range in this respect is extremely limited. The Brain by way of contrast operates on two thousand different wave lengths, which means that The Brain can process at least 2000 problems at one time. Finally, the absence of fatigue in The Brain makes operations possible for 20 out of the 24 hours of the day--the rest of the time we need for servicing and overhauling.”

With apparent effort Scriven turned his face away from the blue flames. His dark brown eyes probed into Lee’s as he summed up:

“All together, Lee, The Brain has now reached the approximate capacity of 25,000 first class human brains. You as a man of vision will understand what that means...”

Lee had his face upturned. The tension of thought gave to his features something of the ecstatic or the somnambulist. Slowly he said:

“The equivalent of twenty-five-thousand human brains--there is no comparison other than a God’s...”

Striven had jumped from his chair. He started pacing the flagstones in front of the fire, whirling his mighty frame around at every corner with a sort of wrath, as if about to meet some attack.

“Yes, you are right,” he almost shouted, “we hold that power; that power almost of a God’s. And how we are wasting it.”

“What do you mean?” Lee’s eye-brows shot up. “You would not waste those powers once you have them. You would turn them to the most constructive use--the advancement of science, of humanity!”

Scriven froze in his steps. A cruel smile parted his lips; there was a gnashing sound of big white teeth. He pointed a finger at his visitor.

“Idealist, eh? That’s what I thought I was ten years ago. That’s what I had in mind with The Brain right from the start. As it has turned out, however, the Army, Navy, Air Force, and half a dozen other government departments, besieged The Brain for the solution of their “problems”, some of them as destructive as warfare, others as insipid as the trend of the popular vote in some provincial primaries. Sometimes Uncle Sam even farms out the services of the Brain to aid some friendly foreign government--without that government’s knowledge as to where the solution is coming from. To cut a long story short: What these fellows utterly fail to understand is that The Brain is not a finite mechanism like any other, but a mechanism which unendingly evolves and becomes richer in its associations by the material which is being fed into its cells. In other words; the Brain learns; consequently it must be taught, it must be given the wherewithal for its own self-improvement...”

Scriven halted his impatient step by the other’s chair. His nervous fingers tapped Lee’s shoulder: “And that is where you come in.”

“Me?” Lee asked, startled. “What you just told me, Dr. Scriven, it will take me weeks to comprehend. At the moment I am at a loss to see how my work could connect...”

The surgeon’s sensitive hand patted Lee’s shoulder as if it were the neck of a shy horse. “You will comprehend--in just another moment.”

He pressed a button; in the entrance to the cabin in the sky the girl appeared, like an apparition. She approached, her hair a golden halo, her tunic transparent against the glare of the summer day. “Yes?”
