“They’re trying to kill me,” Yossarian told him calmly.
“No one’s trying to kill you,” Clevinger cried.
“Then why are they shooting at me?” Yossarian asked.
“They’re shooting at everyone,” Clevinger answered. “They’re trying to kill everyone.”
“And what difference does that make?”

Clevinger was already on the way, half out of his chair with emotion, his eyes moist and his lips quivering and pale. As always occurred when he quarrelled over principles in which he believed passionately, he would end up gasping furiously for air and blinking back bitter tears of conviction. There were many principles in which Clevinger believed passionately. He was crazy.

“Who’s they?” He wanted to know. “Who, specifically, do you think is trying to murder you?”
“Every one of them.” Yossarian told him.
“Every one of whom?”
“Every one of whom do you think?”
“I haven’t any idea.”
“Then how do you know they aren’t?”
“Because…” Clevinger sputtered, and turned speechless with frustration.
