The scene depicts a doctor interacting with Yossarian, highlighting a moment of absurdity and humor. The doctor, a respectable figure, tests Yossarian's vision by asking how many fingers he can see. Despite the changing scenarios, Yossarian consistently responds with "two," illustrating his distorted perception of reality. This exchange serves as a metaphor for the chaotic world in which the characters live, where the truth is subjective and often elusive.
Yossarian's unwavering response, even when the doctor's hand is empty, reflects the overarching themes of Catch-22, where characters are trapped in paradoxical situations. The doctor's delight at Yossarian's repeated answer underscores the farcical nature of the story, demonstrating how sanity and insanity blur. This interaction encapsulates the novel's exploration of war, madness, and the struggle for clarity amidst confusion.
