Part 17 (1/2)

Come on in, the water's fine.”

Bey looked through the forward screen, watching the trail of ionized gases that glowed from Saturn's face behind La.r.s.en's plunging s.h.i.+p. The entry was a daunting prospect. Saturn's surface gravity was almost the same as Earth's, but with an escape velocity more than three times as high, movement to and from low orbit was a difficult feat for any vessel.

”Don't worry, Mr. Wolf.” Capman had come out of his reverie and read theexpression on Bey's face. ”This has all been calculated very closely. Unless there are unknown forces at work in Saturn's lower atmosphere, the danger to John La.r.s.en is very small.”

”And you are intending to follow him down?” asked Bey.

”Perhaps. Let me answer the question behind the question. Obviously, we could have exchanged all the information between us by radio link. Why did I think it necessary to bring you all the way to Saturn in order to talk to each other? After all, in my present form it is obvious that we cannot meet in person, even if there were reason to do so.”

”That will do,” said Bey. ”I might have chosen different words,, but the meaning is the same.”

”Then since I asked your question, would you care to attempt to give my answer?”

Bey smiled. ”There is one obvious answer. You want me to join you in this experiment. To change to the Logian form and descend to the surface of Saturn.”

”And then?”

”As I said, that is the obvious answer. Unless I am losing my ability to read a little deeper, it is not the whole answer. I can't provide the rest of it.”

Capman was sitting perfectly still in his chair, big eyes unblinking, ”It is not simple,” he said. ”Like many things, it involves a choice. Tell me, in your investigation of my background, did you ever see a psychological profile?”

Bey nodded. ”An old one. When you were still in your teens.”

”That would do. Did you notice anything peculiar about it?”

”You're joking, of course. As you know very well, it was simile to mine more similar than I would have thought possible. I must say, I found it very encouraging in some ways. You showed low score on some of the same things as I did intelligence, for instance. Until your profile, mine had always worried me a little.”

”We don't fit well on the standard charts, either of us,” said with the nodding smile of the Logians. ”I doubt if I would fit them at all in this form. But we are a little different-not a lot, but enough to worry me that some people like us are failing the humanity tests. You may be interested to know that you just squeaked through. Well, that is irrelevant at the moment.

Shortage of people is not Earth's current problem. Let me get to the point. I brought you here to offer you a choice. It is one that I would not make to anyone else. I can do it in your case only because we have that curious affinity of mind. Both branches call for self-sacrifice of a sort.”

Bey began to feel again a rise of tension, a suspicion coming from the base of his brain. ”To change to the Logian form and explore Saturn ... ”

Capman nodded. ”Or else?”

”To return to Earth and continue the work on the control of changes? Laszlo Dolmetsch and the others need advice from somebody who really knows form-change theory. If I choose Saturn, you return to Earth yourself.”

”That is correct. If that is your choice, to remain here, I will a.s.sume your outward appearance and go back to Earth. One of us must be there. No one would question Behrooz Wolf's return, or knowledge of form-change.”

”It must be quite obvious to you that I would prefer to stay here. The mental advantages alone of the Logian form are enough to make me want to choose that alternative.”

”I know.” Capman sighed. ”That cannot be denied. All I can say is that the return to Earth, and all its problems, would not be permanent. When Earth's troubles lessen, or become hopeless, or you find and train your own successor, the Saturn experiment will still be here. There will be other work to do-Betha was the first of the Lungfish series, not the last. But it is your decision as to the next step. I am prepared for either role.”

”How much further can form-change be carried? Betha Mestel suggests that we are only at the beginning.”

”We are.” Capman bowed his head. ”I am beginning to suspect that the boundarythat we impose between the animate and the inanimate is an artificial one. If that is true, form-change has no real limits. We can conceive of a conscious, reasoning being as big as a planet, or as big as a star. It would have to be a mixture of organic and inorganic components, just as Betha is; but that presents no logical problems. I have a more fundamental question: At what point would the result cease to be human? If our tests for humanity are valid, any human-or alien-and machine combination that can achieve purposive form-change should be considered human. I can think of worse definitions. Tell me, have you made your decision?”

Bey was silent for several minutes, watching the clouded face of Saturn speeding by below the s.h.i.+p. ”Tell me,” he said at last. ”Do you remember the time that we were in Pleasure Dome, waiting for the decision as to whether they would let us talk to the people who were in charge of the form-change operations?”

”Very well. Why do you ask?”
