"Indeed," Baron Haer said, his nostrils high in that attitude once perfected by grandees of medieval Spain, landed gentry of England, Prussian Junkers. "I find that my sister, in her capacity as medical scientist, seems to go to extreme in her research. What aspect of the lower classes is she studying in your case, major?"

Joe flushed. "Baron Haer," he said, "we seem to have got off on the wrong foot when we participated in that fracas against Continental Hovercraft under your father, the late Baron. I would appreciate an opportunity to start over again."

"Would you indeed?" Balt Haer said loftily. He turned his eye to Philip Holland, whose mouth bore the slightest suggestions of suppressed humor. "Unless I am mistaken, the conversation at the time of my entry seemed to have a distinctly subversive element. Shouldn't this be somewhat surprising in the secretary of the administration's foreign minister?"

Philip Holland said crisply, "You must have intruded, um-m-m, that is, entered, at the end of a sentence, Baron Haer. We were merely discussing the various methods, down through the ages, that ruling classes have utilized to perpetuate themselves in power."

Haer obviously disbelieved him. He said, "For example?"

"There are many examples," Holland said, reseating himself. "For instance, the medieval feudalistic class who dominated the ignorant and highly superstitious serfdom soon found it expedient to add to their titles by grace of God, as though it was God's wish that they be count or baron, prince or king. What serf would dare attempt the overthrow of his lord, in the face of God's wishes?"

"I see," Balt Haer said. "And other examples?"

Holland shrugged. "The Chinese Mandarins utilized possibly the most unique method of a governing class perpetuating itself ever known, certainly one of the most gentle."

Haer was scowling at him, obviously out of his depth, as was Joe Mauser for that matter.

Holland said crisply, "The mandarins devised a written language so complicated that it took at least ten years to master reading and writing, thus assuring that only the very well-to-do could afford to educate their sons. When invaded, as so often China has been invaded, only the mandarins were in the position to serve the conquerors by carrying on the paperwork so vital to any advanced society. So, still in control of the machinery of government, they continued to perpetuate themselves, and shortly—as history is reckoned—we found the conquerors assimilated and the mandarins still in power."
