"You think to escape," he said, in the deadly, expressionless monotone of his kind--the only possible result of orally expressing reason uninfluenced by sentiment. "You will not escape. You are merely the embodiment of two imperfect things--an imperfect brain and an imperfect body. The two cannot exist together in perfection. There you see a perfect body." He pointed toward the rykor. "It has no brain. Here," and he raised one of his chelae to his head, "is the perfect brain. It needs no body to function perfectly and properly as a brain. You would pit your feeble intellect against mine! Even now you are planning to slay me. If you are thwarted in that you expect to slay yourself. You will learn the power of mind over matter. I am the mind. You are the matter. What brain you have is too weak and ill-developed to deserve the name of brain. You have permitted it to be weakened by impulsive acts dictated by sentiment. It has no value. It has practically no control over your existence. You will not kill me. You will not kill yourself. When I am through with you you shall be killed if it seems the logical thing to do. You have no conception of the possibilities for power which lie in a perfectly developed brain. Look at that rykor. He has no brain. He can move but slightly of his own volition. An inherent mechanical instinct that we have permitted to remain in him allows him to carry food to his mouth; but he could not find food for himself. We have to place it within his reach and always in the same place. Should we put food at his feet and leave him alone he would starve to death. But now watch what a real brain may accomplish." He turned his eyes upon the rykor and squatted there glaring at the insensate thing. Presently, to the girl's horror, the headless body moved. It rose slowly to its feet and crossed the room to Luud; it stooped and took the hideous head in its hands; it raised the head and set it on its shoulders. "What chance have you against such power?" asked Luud. "As I did with the rykor so can I do with you." Tara of Helium made no reply. Evidently no vocal reply was necessary. "You doubt my ability!" stated Luud, which was precisely the fact, though the girl had only thought it--she had not said it.
