Yes Indeed

“Oh, I think not,” Varys said, swirling the wine in his cup. “Power is a curious thing, my lord. Perchance you have considered the riddle I posed you that day in the inn?”
“It has crossed my mind a time or two,” Tyrion admitted. “The king, the priest, the rich man—who lives and who dies? Who will the swordsman obey? It’s a riddle without an answer, or rather, too many answers. All depends on the man with the sword.”
“And yet he is no one,” Varys said. “He has neither crown nor gold nor favor of the gods, only a piece of pointed steel.”
“That piece of steel is the power of life and death.”
“Just so… yet if it is the swordsmen who rule us in truth, why do we pretend our kings hold the power? Why should a strong man with a sword ever obey a child king like Joffrey, or a wine-sodden oaf like his father?”
“Because these child kings and drunken oafs can call other strong men, with other swords.”
“Then these other swordsmen have the true power. Or do they?” Varys smiled. “Some say knowledge is power. Some tell us that all power comes from the gods. Others say it derives from law. Yet that day on the steps of Baelor’s Sept, our godly High Septon and the lawful Queen Regent and your ever-so-knowledgeable servant were as powerless as any cobbler or cooper in the crowd. Who truly killed Eddard Stark, do you think? Joffrey, who gave the command? Ser Ilyn Payne, who swung the sword? Or… another?”
Tyrion cocked his head sideways. “Did you mean to answer your damned riddle, or only to make my head ache worse?”
Varys smiled. “Here, then. Power resides where men believe it resides. No more and no less.”
“So power is a mummer’s trick?”
“A shadow on the wall,” Varys murmured, “yet shadows can kill. And ofttimes a very small man can cast a very large shadow.”
Tyrion smiled. “Lord Varys, I am growing strangely fond of you. I may kill you yet, but I think I’d feel sad about it.”
“I will take that as high praise.”

“No man knows how bad he is till he has tried very hard to be good. A silly idea is current that good people do not know what temptation means. This is an obvious lie. Only those who try to resist temptation know how strong it is. After all, you find out the strength of the German army by fighting against it, not by giving in. You find out the strength of a wind by trying to walk against it, not by lying down. A man who gives in to temptation after five minutes simply does not know what it would have been like an hour later. That is why bad people, in one sense, know very little about badness — they have lived a sheltered life by always giving in. We never find out the strength of the evil impulse inside us until we try to fight it: and Christ, because He was the only man who never yielded to temptation, is also the only man who knows to the full what temptation means — the only complete realist.”
― C.S. Lewis

“we fat all creatures else to fat us, and we fat ourselves for maggots. Your fat king and your lean beggar is but variable service, two dishes, but to one table; that's the end.
CLAUDIUS Alas, alas.
HAMLET A man may fish with the worm that hath eat of a king, and eat of the fish that hath fed of that worm.
CLAUDIUS What dost thou mean by this?
HAMLET Nothing but to show you how a king may go a progress through the guts of a beggar.”
― William Shakespeare

“I am so clever that sometimes I don't understand a single word of what I am saying.”
