"I tried to tell him of many others who claimed to have discovered a 'master-mind' that treated humans as we treat goldfish and guinea pigs. I tried to ask him why, if these master minds are so omnipotent that they can spend fifty thousand years watching an experiment in humanity, they were not smart enough to do away with the one man in that time that might cause them trouble. That's the link that stumbles most Prophets of Doom." * * * * * He paused. "But James Forrest Carroll is completely self-justified. His explanation was simple enough to sound right. He merely claimed that, since his mind was sufficiently strong to best their 'hypnosis beams', they kept him alive to study him. You see? He is so mighty that they do not dare. True paranoia. "Now, point three. Carroll is a brilliant man with a vast imagination. Yet his training as a physicist kept him from trying many wild schemes or things that might be against the teachings of modern physics. Therefore he attributes the many superscientific marvels to the techniques of the 'aliens'. In truth no Terran physicist would believe them possible. The conscious mind rejects the idea of the teleport for instance. "But there was terrible compulsion. He must avert the destruction of Sol. This he can do, he believes, by learning much of the alien science and turning their own trick against them. Things that no sensible physicist would even consider must be given a try in this period of emergency. Therefore he went into hallucination in order to invent this 'science'--because his conscious mind tells him that it is impossible." "Aren't you missing the motivation?" asked Majors. "Not at all, I just stated it. His subconscious mind knew that the only way to stop this catastrophe was to try the products of an untrammelled imagination." "Rather complex, don't you think?" "Not to the mind. It is all self-justification. Remember the attack on Rita? Her ribs constricted by a heavy leather strap? A normal man with the impulse to kill doesn't go to such bizarre lengths. A shot, a stab, a bit of poison. "Also," added the psychologist, "it is commentary on the mind of the paranoid that cruel and unusual forms of torture and death are uppermost. Since in Carroll's deluded mind this attack was to be used as proof of the alien culture, the crime must be made to look alien and unearthly. "Well," said Pollard with a deep sigh, "We have smoked him out at last. We have uncovered the hidden truth in Carroll's mind. Rita, we need you again." "I know," she said quietly. "You forgive him?" "Of course," she said. "And if I did not I should cover it. After all, this is no longer a matter of men and women and minor hates. This is Man against the Universe. And if I must sacrifice myself to see that Sol remains I shall, and gladly." "How about your brother?" "He hates Carroll. Terribly." Majors grunted. "We'll take care of him. Maybe he's the real madman in this scramble."
