That, then, was the secret. The principle. But it contained within itself its own difficulty. By "wanting" to activate the Brain he could perhaps actually control some of his actions. But the instant he did something counter to the Cyberene, that control would be taken away from him, and replaced by throbbing pain. He _had_ touched Nadine's hand though. It had been a gesture so unconscious that the Cyberene had been unaware of it until it happened. It was the right direction. * * * * * The possibility of what he wanted to do filled him with a sense of defeat. It would be impossible to falsify the lab report on the nerve fluid. One false word on the card, and the Cyberene would erase it and fill the card out correctly. He fought back the feeling of futility. He reached out, identifying himself with every sensation from his body. He was walking. He _wanted_ to walk. He was talking. He _wanted_ to say what he heard himself say. It would go along well, and then his body would do something he didn't expect, and he would be filled with the realization that he had no control. It would be a mental stumble while his body didn't falter. During each brief period of identifying his desires with his actions, he found his awareness of sensations expand until it was almost complete identification--complete _meshing_. Meshing until the gears were almost strong enough to grip--for a brief second. Perhaps in time they would grip for more than a second before alarm bells rang for the Cyberene. He was alone in his lab. He was placing the fine tubes of test substances in their respective instrument cabinets. Ordinarily he did this almost automatically. Now he watched his every move, building up interest in it, _desiring_ to do everything he did, anticipating what he would do next and wanting to do it, pretending it was he who issued the commands to his muscles. The crucial moment was just ahead. He had stepped to the instrument case that held the key fluid. He started to write down the readings from the instruments. His fingers shook, and it was _his_ nervousness that shook them. A "mistake" in the readings here and there would do it. Speed of ion travel: The meter said two thousand plus feet per second. His fingers wrote the two and a zero. Before he could write the second zero he tried to write the plus sign. Triumphantly he saw his fingers obey his will. Abruptly they paused--and he was aware that a power outside his will had made them pause. Throbbing pain surged up to full intensity, enveloping him, sickening him so that his soul was a writhing thing, unable to think or feel anything other than pain. Slowly it lessened--or was he growing better able to suffer it? Thoughts filtered in to him through gray mists clouding his mind. He saw his hands fill out the rest of the card correctly. He was dimly aware of rushing excitedly from the lab, down the hall, shouting that he had found it.
