The Positronic Man (Page 49)

He was merely having a few interface problems, that was all. But Andrew knew he was fundamentally well and that it would be only a matter of time until he had achieved complete control over his new housing. He had to think of himself as very young, still. Like a child, a newborn child.

The months passed. His coordination improved steadily. He moved swiftly toward full positronic interplay.

Yet not everything was as he would have wished it. Andrew spent hours before the mirror, evaluating himself as he went through his repertoire of facial expressions and bodily motions. And what he saw fell far short of the expectations he had had for his new body.

Not quite human! The face was stiff-too stiff-and he doubted that that was going to improve with time. He would press his finger against his cheek and the flesh would yield, but not in the way that true human flesh would yield. He could smile or scowl or frown, but they were studied, imitative smiles and scowls and frowns. He would give the smile-signal or the frown-signal or whatever, and the muscles of his face would obediently hoist the smile-expression or the frown-expression into view, pulling his features around in accordance with a carefully designed program. He was always conscious of the machinery, organic though it might be, clanking ponderously around beneath his skin to produce the desired effect. That was not how it happened with human beings, Andrew suspected.

And his motions were too deliberate. They lacked the careless free flow of the human being. He could hope that that would come after a while-he was already far beyond the first dismal days after the operation, when he had staggered awkwardly about his room like some sort of crude pre-positronic automaton-but something told him that even with this extraordinary new body he was never going to be able to move in the natural way that virtually every human being took for granted.

Still, things were not all that bad. The U. S. Robots people had kept their part of the bargain honorably and had carried out the transfer with all the formidable technical skill at their disposal. And Andrew had what he wanted. He might not fool the truly observant onlooker into thinking he was human, but he was far more human-looking than any robot ever had been, and at least he could wear clothes now without the ridiculous anomaly of an expressionless metal face rising up above them.

Eventually Andrew declared, "I will be getting back to work now."

Paul Charney laughed and said, "Then you must be well. What will you be doing? Another book?"

"No," said Andrew seriously. "I live too long for anyone career to seize me by the throat and never let me go. There was a time when I was primarily an artist, and I still dabble in that now and then. And there was a time when I was a historian and I can always write another book or two, if I feel the need for it. But I have to keep moving on. What I want to be now, Paul, is a robobiologist."

"A robopsychologist, you mean?"

"No. That would imply the study of positronic brains and at the moment I have no interest in doing that. A robobiologist, it seems to me, would be concerned with the workings of the body that is attached to that brain."

"Wouldn’t that be a roboticist?"

"In the old days, yes. But roboticists work with metallic bodies. I would be studying an organic humanoid body-of which I have the only one, as far as I know. Examining the way it functions, the way it simulates a true human body. I want to know more about artificial human bodies than the android-makers know themselves."

"You narrow your field of endeavor," said Paul thoughtfully. "As an artist, the whole range of expression was yours. Your work could stand up with the best that was being produced anywhere in the world. As a historian, you dealt chiefly with robots. As a robobiologist, your subject will be yourself."

Andrew nodded. "So it would seem."

"Do you really want to turn inward that way?"

"Understanding of self is the beginning of understanding of the entire universe," said Andrew. "Or so I believe now. A newborn child thinks he is the whole universe, but he is wrong, as he soon begins to discover. So he must study what is outside himself-must try to learn where the boundaries are between himself and the rest of the world-in order to arrive at any comprehension of who he is and how he is to conduct his life. And in many ways I am like a newborn child now, Paul. I have been something else before this, something mechanical and relatively easy to understand, but now I am a positronic brain within a body that is almost human, and I can barely begin to comprehend myself. I am alone in the world, you know. There is nothing like me. There never has been. As I move through the world of humans, no one will understand what I am, and I barely understand it myself. So I must learn. If that is what you call turning inward, Paul, so be it. But it is the thing that I must do."

Andrew had to start from the very beginning, for he knew nothing of ordinary biology, almost nothing of any branch of science other than robotics. The nature of organic life, the chemical and electrical basis of it, was a mystery to him. He had never had any particular reason to study it before. But now that he was organic himself-or his body was, at any rate-he experienced a powerful need to expand his knowledge of living things. To understand how the designers of his android body had been able to emulate the workings of the human form, he needed first to know how the genuine article functioned.

He became a familiar sight in the libraries of universities and medical schools, where he would sit at the electronic indices for hours at a time. He looked perfectly normal in clothes and his presence caused no stir whatever. Those few who knew that he was a robot made no attempt to interfere with him.
