With their knowledge, and the popular delusion of their almost supernatural powers, it was easy enough for ambitious men to misuse the Scientists. In some cases, the gamma-men themselves usurped authority, but this noble experiment slipped through their fingers, and they lost control from sheer unworldliness. In truth, from the working of natural law, the juice had run out of them and they no longer understood the basics of normal human relations. In a final paroxysm of public panic, they were disarmed, their toys taken away, and every last gamma-man imprisoned in carefully guarded and isolated colonies. Like the ancient Indians, they were placed in reservations and kept there by force. After this culminating outrage, the gamma-men lost heart for practical activity. Locked into their libraries, they turned to abstractions and dabbled in dead-end philosophies. Most of them were querulous oldsters, hidebound by tradition, their sciences now become a ritual religion, their books exalted as "The Word," and their fading knowledge still held secret for reasons long forgotten. Not quite all gamma-men accepted this half-life allotted to them. There were sports, avatars, occasional throwbacks who rebelled and went "off reservation." None of these actually ran amuck, but so great was the fear-conditioning on one side, and so difficult the adaptation to ordinary living on the other that there were painful accidents and incidents. Nothing genuinely monstrous occurred, but enough friction developed to keep alive and add to the public dread of gamma-men. The term became a byword for nursery terror. And in their turn, the infant generations of gamma-men learned to pity and despise the ignorant and corrupt multitudes of normal humanity. They lost contact with their human heritage. In recent years, few gamma-men had broken out to mingle with the expanding races now peopling and colonizing the frontiers of the solar system. Those few were hunted down like outlaws, and killed with brutal ingenuity. But a new generation had come among gamma-men, with an urge so passionate and devout they themselves did not understand it. Either some latent folk-memory, or some emotional mutation, urged them to go forth and civilize mankind. In the old books, they tracked down knowledge and made grandiose plans for engineering the renaissance. Realizing their common origin, and longing for more nearly normal lives, they grouped together and made a pact to see some changes made. Studying history and the other technologies of man, they soon discovered that social, economic and psychological sciences had lagged far behind the other developments. These were the blind spots of mankind, and these led to all the other serious and tragic misdirections of effort. Always, the sons of Adam had struggled to achieve workable systems, and always these systems had broken down or failed at critical moments. If some means could be found--
