justified in their own minds. Placed in a similar position, Ackerman knew that he would lie, cheat, and steal to save his own earth from destruction. But things were clearer. Ackerman held no illusions now. He pegged Barry Ford right. Ford, of course, was smart; he knew that by this time there could be little chance for blind leading. His sensible course was to admit the conflict and ask Ackerman to view both sides before acting. Also, grinned Ackerman, Barry Ford was smart enough to realize that after having two women hurled at him, Les would be inclined to view any other such acts as sheer folly. The adage said: Once burned, twice shy. After twice scorched, how skittish for the third time? He had completed the circle of thought; he was back to Barry Ford. The third party in this wild game was, unlike the others, set up for laboratory investigation; Les admitted once that he did not know about Tansie Lee and the Blaines. Maybe they were also set up. He hadn't been around that long. Les Ackerman was beginning to understand the basis for the famed General Semantics. It was fine to know what was "truth", or feasible, or "good". It was even better to know what was not "truth", or "good", or feasible; that implied a greater recognition of knowledge. Thomas Edison was reported to have known several thousand things about his nickel storage battery that would not work. The trouble with Ackerman, he himself realized, was that he knew nothing at all. It was an insane program; he was here, aided and working for men who were able to get here because Les had been successful in his work. And then they blithely stated, coldly and calmly, that so soon as he proved himself unable to succeed, they would all disappear! He shook his head, and then grinned. Fervently he prayed that this was not a wild dream; it was such a fearful mess that any waking would be a sorry anticlimax. He recalled Doctor Forbes, the eminent psychiatrist, who once said that there was absolutely no way to prove to one's own satisfaction that he was either dreaming or awake. He remembered that especially because he'd had a dream shortly afterwards in which he dreamed that he had just awakened from a dream. Doctor Forbes had nodded when told, had mentioned that his subconscious had used that method to try to prove to his dreaming mind that the dream was real. He stopped thinking along those lines. That way madness lay. It was reminiscent of the childlike reasoning that asks: "But Daddy, who brings the baby
