"In a state of constant self-suppression, for the one thing their master could not bear was for anyone to disagree with him, to have an opinion apart from his own. What he seemed to seek in his surrounding was a chorus of approval from persons who had sunk their own personalities, submerged them for the the time, while they themselves played the role of listeners. At first I rather despised this complacent courtier-like attitude, yet insensibly I too fell into it, found myself searching for points of agreement with ......., rather than risk displeasing him by any form of polite argument. "
From George, Nicholas and Wilhelm: Three Royal Cousins. The subject was the German ruler Wilhelm II. He does sound a lot like "he who shall not be named." Wilhelm had the attention span off a gnat, hated to read anything of substance, insisted on constant approval, had trouble finishing what he started and so on. The quote was from Anne Topham, an English governess to the German royal family. English governesses were very popular in more than one of the European royal courts.
