There remained, then, the problem of providing a substitute for his own personal survival. Here, the prospect seemed hopeless. The requirements were a continuance of understanding, together with both the will and the ability to act as necessary. Theoretically, he could have forcefully taken possession of the body and mind of any suitable subject, but the mere thought of such a violation was impossibly abhorrent. Respect for the right of the individual to self-will was so deeply ingrained as to make the deliberate unseating of another's reason virtually impossible. On the other hand, free-willed cooeperation and understanding were equally out of reach; to enter the conscious mind of these beings was agony for both parties. They could neither project nor receive thoughts. Ebbing vitality and the increased urgency of the problem drove him to a desperate resource. A pregnant female came within the extreme range of his perception. An embryo mind might serve! The mind, as yet unsullied, sleeping, a blank page untouched by the world, was open to him. If the appropriate knowledge was seeded in its memory banks it might--it _must_--remain sane despite the world, and a sane mind would not dispute what must be done. He made a quick evaluation of the subject mind and discovered the flaw. The intelligence potential was too low. The embryo would not be capable of understanding the planted memories as they came to the conscious level, nor be capable of acting on them if they were understood. Time was ebbing fast, and vitality with it. Very well, then, the most desperate, the most questionable resource of all remained. The unused, unrecognized prime center, true seat of the intellect, must be activated the way nature presumably had intended that it should be, had not something gone wrong in the dawn years of the planet. There could be no moral objection to this measure if successful, since it amounted to giving sight to a blind man. The element of grave doubt lay in the relative chances of success or failure. The strange, interlocking structure of the unconscious mind of the embryo was not something that could be unraveled and examined in a hurry. Honesty compelled him to evaluate himself as young and inexperienced, not especially noted among his own kind for brilliantly incisive judgment. It was not the sort of thing that he should even attempt without long study. It was too risky, too indecisive, too-- Time made the decision. There was no time left. The chill of death told its own story. In an agony of haste he summoned all that remained of vitality and fought off Death while he entered the embryo mind. The fast-shriveling body in the spaceship retained life long enough to recognize the blunder, but not long enough to correct it. The wrong was done, and could not be undone. * * * * *
