Now, finally, Morrison rose, feeling a trifle unsteady on his feet - whether from the vodka, from the general tension of the day, or from this last revelation he did not know or care. He stamped his feet a little, as though to firm them, then deliberately walked the length of the small room and back.

He faced Boranova and said in a harsh voice, "You can miniaturize a rabbit and nothing seems to happen to it. Did it occur to you that the human brain is the most complex bit of matter we know and that, whatever else might survive, the human brain might not?"

"It did," said Boranova stolidly, "but all our investigations have shown us that miniaturization does not in the least affect the interrelationships within the object being miniaturized. In theory, even the human brain would not be affected by miniaturization."

"In theory!" said Morrison with contempt. "How is it possible that, based on theory alone, you would experiment with Shapirov, whose brain you seem to value so highly? And having failed with him, to your enormous loss, how can you be so mad as to propose experimenting with me to recover that loss? You'll simply fail with me, too, and I cannot accept that."

Dezhnev said, "Don't speak nonsense. We are not mad. Nothing we did was lightly undertaken. The fault was Shapirov's."

Boranova said, "In a way, it was. Shapirov had his eccentric ways. 'Crazy Peter' I believe you call him in English and that is perhaps not so far off. He was intent on having the miniaturization experience. He was getting old, he said, and he would not, like Moses, reach the Promised Land without entering it."

"He might have been forbidden to do so."

"By me? I would forbid Shapirov? You can't be serious."

"Not you. Your government. If the miniaturization process is so precious to the Soviet Union -"

"Shapirov threatened to abandon the project altogether if he did not have his way and that could not be risked. Nor is our government quite so high-handed as it once was in its pressures on troublesome scientists. It must take world opinion into greater account now, as your government must. It is the price of global cooperation. Whether that is for the better or for the worse, I cannot say. In any case, Shapirov was eventually miniaturized."

Morrison muttered, "Absolutely mad."

"No," said Boranova, "for we did not move without precautions. Despite the fact that every exercise in miniaturization is costly and sends shivers through the Central Coordinating Committee, we insisted on a careful approach. Twice we miniaturized chimpanzees and twice we brought them back and could detect no changes in them - either as a result of minute studies of their behavior or by magnetic resonance imaging of the brain."

"A chimpanzee is not a human being," said Morrison.

"Something we were aware of," said Boranova gravely. "Therefore, we miniaturized a human being next. A volunteer. Yuri Konev, to be precise."

Konev said, "It had to be me. It was I who felt most strongly that the human brain would not be affected. I am the neurophysicist of the project and it was I who made the necessary calculations. I would not ask another human being to risk his sanity on my calculations and my certainty. Life is one thing - we all lose it sooner or later. Sanity is quite another."

"So brave," whispered Kaliinin, looking at her fingertips, "the deed of a true Soviet hero." Her lip trembled, as though on the brink of a sneer.

Looking firmly at Morrison, Konev said, "I am a loyal Soviet citizen, but I did not do it for nationalist motives. They would be, in this case, irrelevant. I did it as a matter of decency and of scientific ethics. I had confidence in my analysis and of what worth was my confidence if I would not risk myself on it? And it is a matter of something else, too. When the history of miniaturization is recorded, I will be listed as the first human being ever to have been subjected to the process. That will eclipse the deeds of a great-grand-uncle of mine who was a general fighting the German Nazis in the Great Patriotic War. And I would be pleased with that, not out of vainglory but out of a belief that the conquests of peace should always be held superior to victories in war."

Boranova said, "Well, putting ideals to one side and passing on to the facts. Yuri was miniaturized twice. First, he was taken down to about half his height and was restored in perfect order. Then he was miniaturized to the size of a mouse and again was restored in perfect order."

Morrison said, "And then Shapirov?"

"And then Shapirov. He was by no means easy to control even this far. He argued vociferously for the chance to be the first person miniaturized. After Konev's first venture into the small, it was all we could do to persuade him to wait for a second and more drastic attempt. After that we could control him no more. Not only were we forced to miniaturize him, but he swore that he would abandon the project and somehow make his way out of the country to begin a miniaturization project elsewhere if we did not miniaturize him to a greater extent than we had Konev. We had no choice. If 'Crazy Peter,' as you call him, were mad enough to speak of emigrating, that would go beyond what the government would be willing to allow even in these days. We didn't want him in prison, so we miniaturized him to the size of a cell."

"And that passed the limits of safety, did it?"

"No. We have every reason to think he was in perfect order, even miniaturized so far. He was being brought back and then at one point in the deminiaturization there was a misadventure. Deminiaturization took place a trifle too quickly and the temperature rose slightly in Shapirov's body. It had the effect of a high fever - not enough to kill him, but enough to damage his brain permanently. It might have been reversed if we could have attended to him at once, but deminiaturization had to be completed and that took time. It was an appalling catastrophe and all that we can hope for is the chance to salvage what we need from what is left of his brain."

"There may be another misadventure, as you call it, if I were to be miniaturized. Isn't that so?"

"Yes," said Boranova, "that is so. I don't deny it. There have been failures and misadventures throughout the history of science. Surely you need no reminder that there were deaths of cosmonauts in space both on the American and Soviet sides. That did not prevent our present settlement of the moon - and of space itself - as a new home for humanity."

"That may be so, but all advances in space were made by volunteers. No one was launched into space against his will. And I am not volunteering."

Boranova said, "You need not be so frightened of it. We have done our best to make it as safe as possible and, by the way, you will not go alone. Konev and Shapirov did go alone and as bare as the rabbit, for they, like the rabbit, were in a miniaturization field that was encased in air. You, on the other hand, will be in a ship, a kind of modified submarine. It, too, has been miniaturized and deminiaturized without harm. It is a little less expensive to carry through the process with an inanimate object because it can stand a rise in temperature more easily. In fact, such a rise serves to test for the ruggedness and stability of all its components."

"I am not going, Natalya, either alone or with the Red Army."

Boranova ignored the remark. "With you on the ship," she said, "will be we four. Myself, Sophia, Yuri, and Arkady. That is why I have introduced each of them to you. We are all partners in this greatest of all exploring trips. We will not be crossing an ocean or penetrating the vacuum of space. We will instead enter a microscopic ocean and penetrate the human brain. Can you be a scientist - a neurophysicist - and resist that?"
