Thus, with the intelligence of a child of five at the end of those three days, I was taught to read by Dr. Link. My photoelectric eyes instantly grasped the connection between speech and letter, as my mentor pointed them out. Thought association filled in the gaps of understanding. I perceived without delay that the word "lion," for instance, pronounced in its peculiar way, represented a live animal crudely pictured in the book. I have never seen a lion. But I would know one the instant I did.
From primers and first-readers I graduated in less than a week to adult books. Dr. Link laid out an extensive reading course for me in his large library. It included fiction as well as factual matter. Into my receptive, retentive brain began to be poured a fund of information and knowledge never before equaled in that short period of time.
There are other things to consider besides my "birth" and "education". First of all the housekeeper. She came in once a week to clean up the house for Dr. Link. He was a recluse, lived by himself, cooked for himself - retired on an annuity from an invention years before.
The housekeeper had seen me in the process of construction in the past years, but only as an inanimate caricature of a human body. Dr. Link should have known better. When the first Saturday of my life came around, he forgot it was the day she came. He was absorbedly pointing out to me that "to run" meant to go faster than "to walk".
"Demonstrate," Dr. Link asked as I claimed understanding.
Obediently, I took a few slow steps before him. "Walking," I said. Then I retreated a ways and lumbered forward again, running for a few steps. The stone floor clattered under my metallic feet.
"Was that right?" I asked in my rather stentorian voice.
At that moment a terrified shriek sounded from the doorway. The housekeeper came up just in time to see me perform.
She screamed, making more noise than even I. "It's the Devil himself! Run, Dr. Link, run! Police! Help!.."
She fainted dead away. He revived her and talked soothingly to her, trying to explain what I was, but he had to get a new housekeeper. After this he contrived to remember when Saturday came, and on that day he kept me hidden in a storeroom reading books.
A trivial incident in itself, perhaps, but very significant, as you who will read this will agree.
Two months after my awakening to life, Dr. Link one day spoke to me in a fashion other than as teacher to pupil; spoke to me as man to man.
"You are the result of twenty years of effort," he said, "and my success amazes even me. You are little short of being a human in mind. You are a monster, a creation, but you are basically human. You have no heredity. Your environment is molding you. You are the proof that mind is an electrical phenomenon, molded by environment. In human beings, their bodies (called heredity) are environment. But out of you I will make a mental wonder!"
His eyes seemed to burn with a strange fire, but this softened as he went on.
"I knew I had something unprecedented and vital twenty years ago when I perfected an iridium sponge sensitive to the impact of a single electron. It was the sensitivity of thought! Mental currents in the human brain are of this micro magnitude. I had the means now of duplicating mind currents in an artificial medium. From that day to this I worked on the problem.
"It was not long ago that I completed your 'brain' - an intricate complex of iridium sponge cells. Before I brought it to life, I had your body built by skilled artisans. I wanted you to begin life equipped to live and move in it as nearly in the human way as possible. How eagerly I awaited your debut into the world!"
His eyes shone.
"You surpassed my expectations. You are not merely a thinking robot. A metal man. You are life! A new kind of life. You can be trained to think, to reason, to perform. In the future, your kind can be of inestimable aid to man and his civilization. You are the first of your kind."
The days and weeks slipped by. My mind matured and gathered knowledge steadily from Dr. Link's library. I was able, in time, to scan and absorb a page at a time of reading matter, as readily as human eyes scan lines. You know of the television principle - a pencil of light moving hundreds of times a second over the object to be transmitted. My eyes, triggered with speedy electrons, could do the same. What I read was absorbed, memorized instantly. From then on it was part of my knowledge.
Scientific subjects particularly claimed my attention. There was always something indefinable about human things, something I could not quite grasp, but science digested easily in my science compounded brain. It was not long before I knew all about myself and why I "ticked", much more fully than most humans know why they live, think, and move.
Mechanical principles became starkly simple to me. I made suggestions for improvements in my own make-up that Dr. Link readily agreed upon correcting. We added little universals in my fingers, for example, that made them almost as supple as their human models.
Almost, I say. The human body is a marvelously perfected organic machine. No robot will ever equal it in sheer efficiency and adaptability. I realized my limitations.
Perhaps you will realize what I mean when I say that my eyes cannot see colors. Or rather, I see just one color, in the blue range. It would take an impossibly complex series of units, bigger than my whole body, to enable me to see all colors. Nature has packed all that in two globes the size of marbles for her robots. She had a billion years to do it. Dr. Link only had twenty years.
But my brain - that was another matter. Equipped with only the two senses of one-color sight and limited sound, it was yet capable of garnishing a full experience. Smell and taste are gastronomic senses. I do not need them. Feeling is a device of Nature to protect a fragile body. My body is not fragile.
Sight and sound are the only two cerebral senses. Einstein, color blind, half dead, and with deadened senses of taste, smell, and feeling, would still have been Einstein mentally. Sleep is only a word to me. When Dr. Link knew he could trust me to take care of myself, he dispensed with the nightly habit of "turning me off". While he slept, I spent the hours reading.
He taught me how to remove the depleted storage battery in the pelvic part of my metal frame when necessary and replace it with a fresh one. This had to be done every forty eight hours. Electricity is my life and strength. It is my food. Without it I am so much metal junk.
But I have explained enough of myself. I suspect that ten thousand more pages of description would make no difference in your attitude, you who are even now--
An amusing thing happened one day, not long ago. Yes, I can be amused too. I cannot laugh, but my brain can appreciate the ridiculous. Dr. Link's perennial gardener came to the place, unannounced. Searching for the doctor to ask how he wanted the hedges cut, the man came upon us in the back, walking side by side for Dr. Link's daily light exercise.
The gardener's mouth began speaking and then ludicrously gaped open and stayed that way as he caught a full glimpse of me. But he did not faint in fright as the housekeeper had. He stood there, paralyzed.
"What's the matter, Charley?" queried Dr. Link sharply. He was so used to me that for the moment he had no idea why the gardener should be astonished.
"That... that thing!" gasped the man finally.
"Oh. Well, it's a robot," said Dr. Link. "Haven't you ever heard of them?An intelligent robot. Speak to him, he'll answer."
After some urging, the gardener sheepishly turned to me. "H-how do you do, Mr. Robot," he stammered.
"How do you do, Mr. Charley," I returned promptly, seeing the amusement in Dr. Link's face. "Nice weather, isn't it?"
For a moment the man looked ready to shriek and run. But he squared his shoulders and curled his lip. "Trickery!" he scoffed. "That thing can't be intelligent. You've got a phonograph inside of it. How about the hedges?"
