"Now, further suppose that this system, this field of knowledge is, right now, in constant use by millions of human beings, even though most of them are unaware of the implications of the entire field. Could Snook.u.ms work with such a body of knowledge?"
"Sure," said Leda. "Why not?"
"What if there was absolutely no way for Snook.u.ms to experiment with this knowledge? What if he simply did not have the equipment necessary?"
"You mean," she asked, "something like astrophysics?"
"No. That"s exactly what I don"t mean. I"m perfectly well aware that it isn"t possible to test astrophysical theories directly. n.o.body has been able to build a star in the lab so far.
"But it _is_ possible to test the theories of astrophysics a.n.a.logically by extrapolating on data that _can_ be tested in a physics lab.
"What I"m talking about is a system that Snook.u.ms, simply because he is what he is, cannot test or experiment upon, in any way whatsoever. A system that has, in short, no connection with the physical world whatsoever."
Leda Crannon thought it over. "Well, a.s.suming all that, I imagine that it would eventually ruin Snook.u.ms. He"s built to experiment, and if he"s kept from experimenting for too long, he"ll exceed the optimum randomity of his circuits." She swallowed. "If he hasn"t already."
"I thought so. And so did someone else," said Mike thoughtfully.
"Well, for Heaven"s sake! What is this system?" Leda asked in sudden exasperation.
"You"re close," said Mike the Angel.
"What are you talking about?"
"Theology," said Mike. "He was pumped full of Christian theology, that"s all. Good, solid, Catholic theology. Bishop Costin"s mathematical symbolization of it is simply a result of the verbal logic that had been smoothed out during the previous two thousand years. Snook.u.ms could reduce it to math symbols and equations, anyway, even if we didn"t have Bishop Costin"s work."
He showed her the book from Mellon"s room.
"It doesn"t even require the a.s.sumption of a soul to make it foul up a robot"s works. He doesn"t have any emotions, either. And he can"t handle something that he can"t experiment with. It would have driven him insane, all right. But he _isn"t_ insane."
Leda looked puzzled. "But--"
"Do you know why?" Mike interrupted.
"No."
"Because he found something that he could experiment with. He found a material basis for theological experimentation."
She looked still more puzzled. "What could that be?"
"Me," said Mike the Angel. "Me. Michael Raphael Gabriel. I"m an angel--an archangel. As a matter of fact, I"m _three_ archangels. For all I know, Snook.u.ms has equated me with the Trinity."
"But--how did he get that idea?"
"Mostly from the Book of Tobit," said Mike. "That"s where an archangel takes the form of a human being and travels around with Tobit the Younger, remember? And, too, he probably got more information from the first part of Luke"s Gospel, where Gabriel tells the Blessed Virgin that she"s about to become a mother."
"But would he have figured that out for himself?"
"Possibly," said Mike, "but I doubt it. He was told that I was an angel--literally."
"Let me see that book," she said, taking _The Christian Religion and Symbolic Logic_ from Mike"s hand. She opened it to the center. "I didn"t know anyone had done this sort of work," she said.
"Oh, there was a great fuss over the book when it came out. There were those who said that the millennium had arrived because the truth of the Christian faith had been proved mathematically, and therefore all rational people would have to accept it."
She leafed through the book. "I"ll bet there are still some who still believe that, just like there are some people who still think Euclidian geometry must necessarily be true because it can be "proved"
mathematically."
Mike nodded. "All Bishop Costin did--all he was _trying_ to do--was to prove that the axioms of the Christian faith are logically self-consistent. That"s all he ever claimed to have done, and he did a brilliant job of it."
"But--how do you know this is what Snook.u.ms was given?"
"Look at the pages. Snook.u.ms" waldo fingers wrinkled the pages that way.
Those aren"t the marks of human fingers. Only two of Mellon"s other books were wrinkled that way."
She jerked her head up from the book, startled. "_What?_ This is Lew Mellon"s book?"
"That"s right. So are the other two. A Bible and a theological dictionary. They"re wrinkled the same way."
Her eyes were wide, bright sapphires. "But _why_? Why would he do such a thing, for goodness" sake?"
"I don"t know why it was done," Mike said slowly, "but I doubt if it was for goodness" sake. We haven"t gotten to the bottom of this hanky-panky yet, I don"t think.
"Leda, if I"m right--if this _is_ what has been causing Snook.u.ms" odd behavior--can you cure him?"
She looked at the book again and nodded. "I think so. But it will take a lot of work. I"ll have to talk to Fitz about it. We"ll have to keep this book--and the other two."
Mike shook his head. "No can do. Can you photocopy them?"
"Certainly. But it"ll take--oh, two or three hours per book."
"Then you"d better get busy. We"re landing in the morning."
She nodded. "I know. Captain Quill has already told us."
"Fine, then." He stood up. "What will you do? Simply tell Snook.u.ms to forget all this stuff?"
"Good Heavens no! It"s too thoroughly integrated with every other bit of data he has! You might be able to take one single bit of data out that way, but to jerk out a whole body of knowledge like this would completely randomize his circuits. You can pull out a tooth by yanking with a pair of forceps, but if you try to take out a man"s appendix that way, you"ll lose a patient."
"I catch," Mike said with a grin. "Okay. I"ll get the other two books and you can get to work copying them. Take care."
"Thanks, Mike."
As he walked down the companionway, he cursed himself for being a fool.
If he"d let things go on the way they were, Leda might have weaned herself away from Snook.u.ms. Now she was interested again. But there could have been no other way, of course.
