"You must believe," she said, "because it is true. I am completely human in a physical way, with warm human blood in my veins, and a heart that beats steadily; and I can be stirred to passion like any young girl by the caresses of a lover. Even my mind is human, although there may be certain differences. If you could see my brain it would not startle you. No medical student would be puzzled or disturbed by it. It is no larger or in any way different from the brain of a quite ordinary woman."
She paused and moistened her lips, still looking at him steadily. "I have warm blood in my veins and I can be as yielding and generous as any man could desire. But I'm unlike any other woman. I was never born."
He started to speak, but she silenced him with a gesture. "Don't look so startled. Have I not prepared your mind for such a revelation? Does it not follow the pattern of your thoughts a moment ago, when our thoughts merged? I was never born. I was laboratory-created. But I was not created by human science. Human science has soared miraculously and a tiny, furry creature with bulging eyes has descended from the trees and become a big-brained biped who has exploded the energies at the core of matter, explored the universe through a great, stationary eye for millions of light years and may yet succeed in disrupting a sun, and hurling a blinding incandescence through space as a symbol of what Man alone can accomplish."
She nodded, her eyes beginning to shine. "Yes, human science can accomplish miracles, but it has not yet succeeded in reproducing the human form in all of its complexity—brain, heart, arteries, bone structure, the pulse of life itself—within a transparent incubator bright with nutrient fluids, weaving filaments of flame, stabbing needles of nuclear energy...."
She stopped, her breath quickening, and lowered her eyes. "I have told you too much," she went on with a slight tremor in her voice, as if she were forcing herself to remain calm, but knew that she was treading on dangerous ground. "There are some things I can't tell you. They would destroy me instantly if I told you more than a small part of what I know. I am in danger because you discovered the disk which controls my breathing, my pulse rate, and my ability to move about at will. But you are in much greater danger. You are in danger because you were able to resist me. They may feel that their plans are in jeopardy."
"Their plans—"
"Let me talk. Let me say what has to be said now, before I think about it too much and fear make a coward of me. If you who are a fool for love—I am only repeating what you told me and what they believe about you—if even you could resist me, more hard-headed, practical men who think of love only as a diversion, and often hate themselves when they succumb to it, men who sit in high places and rule the Earth with a humorless kind of harshness, may not succumb at all."
She had raised her eyes and was looking at him steadily again, with an unexpected warmth and sympathy in her gaze. "It is not a mistake to think of love as the most important thing in life. I agree with you. It is. There is a greatness in living that only love can make complete and glorious. Even though I am not completely human I know that without desire, without the need to give and receive love, my brain and heart would shrivel. But not all women feel that way. And not all men. There are some men who so despise love that they think of it as shameful, the physical act of love as a degradation."
"I know," Loring said. "And they are tragically crippled men."
"You are not crippled," she said. "That is why you were chosen. They had to make a test first, a carefully controlled exploratory—" She hesitated, an evanescent smile hovering for the barest instant on her lips and then vanishing, leaving her eyes even more deeply troubled.—"The technical term for it, in human laboratory experiments is, I believe, 'test run.' They had to make a test run with just one man and one woman before my great beauty could be transformed into a weapon for the conquest of Earth."
