"Kendrick, in one demonstration, took a young man who was very much in love with a certain young lady. A really love-sick lad. He placed him in the recording unit gave him the young lady's picture, and told him to let his mind dwell on her to the exclusion of all else." Doctor Entman smiled briefly. "This, I imagine, wasn't difficult for the lad to do. Entman then put another young man, one who was unacquainted with the girl, into a receiving unit and exposed him, after giving him the girl's picture, to the vibrations created by the lovelorn chap. Later, they saw to it that the second lad was introduced to the girl. The results were rather startling, in that the young lady suddenly had two ardent suitors in place of one." Brent Taber scratched his ear and looked dubious. "That sounds pretty sensational. But maybe the second lad just plain happened to fall in love with the girl by natural processes." "True, but the experiments tended to eliminate that possibility. Other emotions were tested. How about a man walking up to a man he'd never seen before in his life and busting him in the nose?" "Okay, okay. Then you think--" "I think a lot of things. Here, I see the possibility of a race with superior science, having moved far ahead of us in the directions Kendrick is pointing toward in his research. For instance, with more advanced knowledge and know-how, they've probably been able to charge a synthetic body with a complete set of functioning emotional responses. Grant them that and we can also concede a tailor-made ego." "I don't mind admitting I'm scared, Doctor," Brent Taber said. "I think it's a time to be scared." "But if a race of people were that advanced, if their intention is hostile, why do they pussyfoot around this way? Why don't they just come down and take us over?" "I've wondered that, too. And yet, a race on some planet out there in the universe might not evolve according to what we consider a logical pattern." "What do you mean?" "I mean that while they can create a synthetic man, their interests, and therefore their progress, may have stayed in peaceful channels. For instance, they may not have bothered with anything as elementary as the atom bomb." "It's a thought." "A wishful thought, I'll admit. But it does have some validity. Also, it has a fact of some possible value to back it up." "What fact?" "That they _haven't_ come down and taken us over." "You almost cheer me, Doctor. Almost, but not quite." "Actually," Entman said, "I've been wondering about something else." "What's that?" "When and how they came here before." "You mean, where did they get the model for the ten androids?"
