"He knows more about his field than anybody else does." "He _seems_ to, you mean. And therefore, anything he says about it carries more weight than what anybody else says. Other workers follow his lead. He developes ideas, formulates theories--and then _defends them for all he's worth_." "But why shouldn't he?" "Because a man can't fight for his life and reputation and still keep his objectivity," said Lessing. "And what if he just happens to be wrong? Once he's an Authority the question of what's right and what's wrong gets lost in the shuffle. It's _what he says_ that counts." "But we _know_ you're right," Dorffman protested. "Do we?" "Of course we do! Look at our work! Look at what we've seen on the Farm." "Yes, I know." Lessing's voice was weary. "But first I think we'd better look at Tommy Gilman, and the quicker we look, the better--" A nurse greeted them as they stepped off the elevator. "We called you at the Farm, but you'd already left. The boy--" She broke off helplessly. "He's sick, Doctor. He's sicker than we ever imagined." "What happened?" "Nothing exactly--happened. I don't quite know how to describe it." She hurried them down the corridor and opened a door into a large children's playroom. "See what you think." The boy sat stolidly in the corner of the room.

"Go away, go away--" When Lessing persisted the boy bent over swiftly and bit him hard on the hand. Lessing sat down on the table. "Tommy, listen to me." His voice was gentle. "I won't try to take it again. I promise." "Go away." "Do you know who I am?" Tommy's eyes shifted haltingly to Lessing's face. He nodded. "Go away." "Why are you afraid, Tommy?" "I hurt. My head hurts. I hurt all over. Go away." "Why do you hurt?" "I--can't get it--off," the boy said. _The monitor_, Lessing thought suddenly. Something had suddenly gone horribly wrong--could the boy really be sensing the source of the trouble? Lessing felt a cold knot gather in the pit of his stomach. He knew what happened when adult psi-contact struck a psi-high youngster's mind. He had seen it a hundred times at the Farm. But even more--he had felt it in his own mind, bursting from the child. Like a violent physical blow, the hate and fear and suspicion and cruelty buried and repressed in the adult mind, crushing suddenly into the raw receptors of the child's mind like a smothering fog--it was a fearful thing. A healthy youngster could survive it, even though the scar remained. But this youngster was sick--
