Quote 1
"No, my friend. We are lunatics from the hospital up the highway, psycho-ceramics, the cracked pots of mankind. Would you like me to decipher a Rorschach for you? No? You must burry on? Ah, he's gone. Pity." He turned to McMurphy. "Never before did I realize that mental illness could have the aspect of power, power. Think of it: perhaps the more insane a man is, the more powerful he could become. Hitler an example. Fair makes the old brain reel, doesn't it? Food for thought there." (3.2.102)
Harding realizes that mental illness has the power to invoke fear and, thus, to manipulate people.

"You have more to lose than I do," Harding says again. "I'm voluntary. I'm not committed."
McMurphy doesn't say a word. He's got that same puzzled look on his face like there's something isn't right, something he can't put his finger on. He just sits there looking at Harding, and Harding's rearing smile fades and he goes to fidgeting around from McMurphy staring at him so funny. He swallows and says, "As a matter of fact, there are only a few men on the ward who are committed. Only Scanlon and—well, I guess some of the Chronics. And you. Not many commitments in the whole hospital. No, not many at all."
Then he stops, his voice dribbling away under McMurphy's eyes. After a bit of silence McMurphy says softly, "Are you bullshitting me?" Harding shakes his head. He looks frightened. McMurphy stands up in the hall and says, "Are you guys bullshitting me!" Nobody'll say anything. McMurphy walks up and down in front of that bench, running his hand around in that thick hair. He walks all the way to the back of the line, then all the way to the front, to the X-ray machine. It hisses and spits at him. "You, Billy—you must be committed, for Christsakes!"

"Sefelt, what about you? There's nothing wrong with you but you have fits. Hell, I had an uncle who threw conniptions twice as bad as yours and saw visions from the Devil to boot, but he didn't lock himself in the nuthouse. You could get along outside if you had the guts—"
"Sure!" It's Billy, turned from the screen, his face boiling tears. "Sure!" he screams again. "If we had the g-guts! I could go outside to-today, if I had the guts. My m-m-mother is a good friend of M-Miss Ratched, and I could get an AMA signed this afternoon, if I had the guts!" (2.7.54-65)
McMurphy suddenly realizes that most of the men are in the asylum voluntarily; the most sane person there is also the one kept against his will, while the craziest men are there of their own volition. It’s because they’re too scared to be anywhere else.
