"Postulate that the Masters, in many thousands of cycles of study, made advances in science that were not reduced to practice; that the Omans either possessed this knowledge or had access to it; and that Omans and humans cooperated fully in sharing and in working with all the knowledges thus available. From these three postulates the conclusion can be drawn that there has come into existence a new race. One combining the best qualities of both humans and Omans, but with the weaknesses of neither."

"An unpleasant thought, truly," Ynos thought. "But you can now, I suppose, design the generators and projectors of a force superior to that screen."

"Data insufficient. I can equal it, since both generation and projection are implicit in the formula. But the data so adduced are in themselves vastly ahead of anything previously in my banks."

"Are there any other races in this Galaxy more powerful than the postulated one now living on Fuel World?"
