He chose ... but he made one error...._ BY FRANCIS DONOVAN Illustrated by Rogers I An embryo stirred very slightly in the warm, dark womb that held it. Chemical stimuli and minute pulses of energy that were forming the complex proteins faltered. A catalyst failed briefly in its task, then resumed, but the damage had been done. A vital circuit remained incomplete, a neural path blocked. Time passed.... * * * * * An embryo gathered in a metal womb, controlled potential building to titanic birth. A thread of wire melted under a breath of energy and a tiny, glowing light winked out. A rodentlike maintenance robot, scurrying to an unimportant repair task, saw no warning signal and crossed a control panel from behind at the moment that a relay closed automatically. Obliterated, the robot only briefly interfered with the proper functioning of the machine, but the damage had been done. For a split second at a critical moment, a mighty engine reacted out of control. Time passed.... * * * * * An embryo jerked convulsively under a frightful onslaught, strained for life in a crowded womb while the mother's convulsions threatened it with death. The convulsions passed, the mother lived, the womb emptied, but the damage had been done, a record had been cut. Time passed.... II There are logical limits for any pretense--limits beyond which the pretense becomes demonstrably absurd. Mother-love enabled the woman Helen Douglas to evade logic up to and beyond the point of absurdity, but even mother-love is not proof against the turmoil of the subconscious. A survival factor pried up a safety valve, and Helen Douglas found herself suddenly face to face with the admission that she had so desperately suppressed. She reacted with a terrible storm of weeping that shook the bed and was watched with complete disinterest by the dry-eyed imbecile beside her. Two-year-old Timothy Wainwright Douglas, congenital idiot, couldn't care less. It was nothing to him that his mother had at last faced the ugly knowledge that her only child should have been born dead. It was less than nothing to him that she could almost find it in her heart to wish him dead. * * * * *
