"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:
