gene combination might produce a human being more content to leave decisions to you, more willing to believe in your resolve to make men happy, more eager to be happy. I cannot find the proper combination, but you might, and with guided genetic engineering . . .” "I see what you mean. It is ... good. I will devote some time to it.” *** Bakst found it difficult to hitch into Noreen's private wave length. Three times the connection broke away. He was not surprised. In the last two months, there had been an increasing tendency for technology to slip in minor ways-never for long, never seriously-and he greeted each occasion with a somber pleasure. This time it held. Noreen's face showed, holographically three-dimensional. It flickered a moment, but it held. "I'm returning your call," said Bakst, dully impersonal. "For a while it seemed impossible to get you,"- said Noreen. "Where have you been?" "Not hiding. I'm here, in Denver." "Why in Denver?" "The world is my oyster, Noreen, I may go where I please." Her face twitched a little. "And perhaps find it empty everywhere. We are going to try you, Ron." "Now?" "Now!" "And here?" "And here!" Volumes of space flickered into different glitters on either side of Noreen, and further away, and behind. Bakst looked from side to side, counting. There were 14, six men, eight women. He knew every one of them. They had been good friends once, not so long ago. To either side and beyond the simulacra was the wild background of Colorado on a pleasant summer day that was heading toward its end. There had been a city here once named Denver. The site still bore the name though it had been cleared, as most of the city sites had been. He could count 10 robots in sight, doing whatever it was robots did. They were maintaining the ecology, he supposed. He knew no details, but Multivac did, and it kept 50 million robots all over the Earth in efficient order. Behind Bakst was one of the converging grids of Multivac, almost like a small fortress of self-defense. "Why now?" he asked. "And why here?" Automatically, he turned to Eldred. She was the oldest of them and the one with authority - if a human being could be said to have authority. Eldred's dark-brown face looked a little weary. The years showed, all six score of them, but her voice was firm and incisive. "Because we have the final fact now. Let Noreen tell you. She knows you best." Bakst's eyes shifted to Noreen. "Of what crime am I accused?" "Let us play no games, Ron. There are no crimes under Multivac except to strike for freedom and it is a human crime that you have committed, no crime under Multivac. For that we will judge whether any human being alive wants your company any longer, wants to hear your voice, be aware of your presence, or respond to you in any way." "Why am I threatened with isolation then?" "You have betrayed all men." "How?" "Do you deny that you seek to breed mankind into subservience to Multivac." "Ah!" Bakst folded his arms across his chest. "You found out quickly, but then you had only to ask Multivac." Noreen asked, "Do you deny that you asked for help in the genetic engineering of a strain of humanity designed to accept slavery under Multivac without question?" "I suggested -the breeding of a more contented humanity. ls this a betrayal?" Eldred intervened. She said, "We don't want your sophistry, Ron. We know it by heart. Don't tell us once again that Multivac cannot be withstood, that there is no use in struggling, that we have gained security. What you call security, the rest of us call slavery." Bakst said, "Do you proceed now to judgment, or am I allowed a defense?" "You heard Eldred," said Noreen. "We know your defense." "We all heard Eldred," said Bakst, "but no one has heard me. What she says is my defense is not my defense.” There was a silence as the images glanced right and left at each. other. Eldred said, "Speak!" Bakst said, "I asked Multivac to help me solve a problem in the field of mathematical games. To gain its interest, I pointed out that the problem was modeled on gene combinations and that a solution might help in designing a gene combination that would leave man no worse off than he is now in any respect and yet breed into him a cheerful acceptance of Multivac's direction and acquiescence in its decisions." "So we have said," said Eldred. "It was only on those terms that Multivac would have accepted the task. Such a new breed is clearly desirable for mankind by Multivac's standards, and by Multivac's standards it must labor toward that. And the desirability of the end will lure it on to examine greater and greater complications of a problem whose endlessness is beyond what even it can handle. You all witness that." Noreen said, "Witness what?" "Haven't you had trouble reaching me? In the last two months, hasn't each of you noticed small troubles in what has always gone smoothly. You are silent. May I accept that as an affirmative?" "If so, what then?" Bakst said, "Multivac has been placing all its spare circuits on the problem. It
