Staring at the informer's face, Barrent remembered. In an overpowering flood of memory he saw himself, a little boy, entering the closed classroom. He heard again the soothing hum of machinery, watched the pretty lights blink and flash, heard the insinuating machine voice whisper in his ear. At first, the voice filled him with horror; what it suggested was unthinkable. Then, slowly, he became accustomed to it, and accustomed to all the strange things that happened in the closed classroom.
He learned. The machines taught on deep, unconscious levels. The machines intertwined their lessons with the basic drives, weaving a pattern of learned behavior with the life instinct. They taught, then blocked off conscious knowledge of the lessons, sealed it—and fused it.
What had he been taught? For the social good, you must be your own policeman and witness. You must assume responsibility for any crime which might conceivably be yours.
The face of the informer stared impassively at him. It was Barrent's own face, reflected back from a mirror on the wall.
He had informed on himself. Standing with the gun in his hand that day, looking down at the murdered man, learned unconscious processes had taken over. The presumption of guilt had been too great for him to resist, the similarity to guilt had turned into guilt itself. He had walked to the robot-confessor's booth, and there he had given complete and damning evidence against himself, had indicted himself on the basis of probability.
The robot-confessor had passed the obligatory sentence and Barrent had left the booth. Well-trained in the lessons of the classroom, he had taken himself into custody, had gone to the nearest thought-control center in Trenton. Already a partial amnesia had taken place, keyed to and triggered by the lessons of the closed classroom.
The skilled android technicians in the thought-control center had labored hard to complete this amnesia, to obliterate any remnants of memory. As a standard safeguard against any possible recovering of his memory, they had implanted a logical construct of his crime beneath the conscious level. As the regulations required, this construct contained an implication of the far-reaching power of Earth.
When the job was completed, an automatized Barrent had marched out of the center, taken a special expressway to the prison ship depot, boarded the prison ship, entered his cell, and closed the door and left Earth behind him. Then he had slept until the checkpoint had been passed, after which the newly arrived guards awakened the prisoners for disembarkation on Omega....
Now, staring at his own face in the mirror, the last of the conscious lessons of the classroom became conscious:
The lessons of the closed classroom must never be consciously known by the individual. If they become conscious the human organism must perform an immediate act of self-destruction.
