"You realize, of course, that it is your duty to acquaint Leader Marley with all the details of your discovery?"

"Is it? Can you imagine what this will do to our society? What about the generations of children coming into a world where no places have been vacated for them by death? What about the struggles for power? Who will decide, and on what basis, whether to confer or to withhold this gift? There'll be riots, civil wars. I know that I'm only a scientist; all I ever wanted from life was to be left alone, in a peaceful laboratory, and let other people worry about the world and its troubles. But now—don't you see that by the mere fact that I made this discovery, I've lost the right to sit by quietly and let other people make the decisions?"

"But, David, you and I aren't able to handle such a problem! We're only Research!"

"I know. We're inadequate, yet we have the responsibility. The men who created atomic power probably felt inadequate, too, but could they have made as bad a mess of handling it as others did? Suppose I did turn this over to Marley—he'd use it to become the most absolute tyrant in the history of the race."

Karl ran his fingers through his hair and smiled crookedly. "Well, you could always start a revolution, I suppose, and start by assassinating the Leader."

"With what kind of weapon? Men like you and me are not allowed to own so much as an old-fashioned pistol. Except for the Military, Marley's the only man allowed to wear a Needler. And, besides, I'm a Research, not a Military. I hate violence and I'm naturally conditioned against killing."

"Then you shouldn't have got into this mess. It would have been far better never to have discovered this SDE. I presume your notes are safely locked up, by the way?"

David grinned. "Don't worry about my notes; they're written in Coptic. You remember when I was still in Medschool and made my first important discovery, how to prevent the development of hereditary baldness by the injection of certain parahormones? Leader Marley rewarded me with a Free Choice, and I chose to learn a dead language. Not half a dozen men in the world could read my notes."

"If your notes are safe, why don't you just destroy your mice and get rid of your proof that way?"

"And the Hachovnik twins?"
