The quote from Ken Kesey's "One Flew Over the Cuckoo's Nest" reflects a strong sense of defiance and confidence in the face of adversity. It suggests that the speaker possesses knowledge or strength that others underestimate, leading them to feel overly assured. This insight speaks to the dynamics of power and perception within the story, particularly concerning the characters' struggles against oppressive authority.

This statement encapsulates the theme of rebellion against societal norms and the courage required to assert one's individuality. It highlights the notion that those in power often fail to recognize the resilience and potential of those they seek to control, hinting at an underlying tension that drives the narrative forward. The tension between confidence and arrogance is a central component of the character's journey throughout the novel.
