Since the human body is chemical and electrical, increased knowledge of its powers and limitations will enable us to work with Nature in her sublime but infinitely slow processes of human evolution. We need not wait another fifty thousand years to be godlike creatures. Perhaps even now we may be standing at the beginning of the splendid bridge that will take us to that state of perfected evolution when we shall be Creatures who have reached the Light. Northwood looked questioningly at the professor. "Queer, fantastic thing, isn't it?" * * * * * Professor Michael smoothed his thin, gray hair with his dried-out hand. "Fantastic?" His intellectual eyes behind the thick glasses sought the ceiling. "Who can say? Haven't you ever wondered why all parents expect their children to be nearer perfection than themselves, and why is it a natural impulse for them to be willing to sacrifice themselves to better their offspring?" He paused and moistened his pale, wrinkled lips. "Instinct, Northwood. We Creatures of the Light know that our race shall reach that point in evolution when, as perfect creatures, we shall rule all matter and live forever." He punctuated the last words with blows on the table. Northwood laughed dryly. "How many thousands of years are you looking forward, Professor?" The professor made an obscure noise that sounded like a smothered sniff. "You and I shall never agree on the point that mental advancement may wipe out physical limitations in the human race, perhaps in a few hundred years. It seems as though your profound admiration for Dr. Mundson would win you over to this pet theory." "But what sane man can believe that even perfectly developed beings, through mental control, could overcome Nature's fixed laws?" "We don't know! We don't know!" The professor slapped the magazine with an emphatic hand. "Emil Mundson hasn't written this article for nothing. He's paving the way for some announcement that will startle the scientific world. I know him. In the same manner he gave out veiled hints of his various brilliant discoveries and inventions long before he offered them to the world." "But Dr. Mundson is an electrical wizard. He would not be delving seriously into the mysteries of evolution, would he?" "Why not?" The professor's wizened face screwed up wisely. "A year ago, when he was back from one of those mysterious long excursions he takes in that weirdly different aircraft of his, about which he is so secretive, he told me that he was conducting experiments to prove his belief that the human brain generates electric current, and that the electrical impulses in the brain set up radioactive waves that some day, among other miracles, will make thought communication possible. Perfect man, he says, will perform mental feats which will give him complete mental domination over the physical." * * * * *
