"One Flew Over the Cuckoo's Nest" by Ken Kesey explores the themes of sanity, freedom, and the struggle against oppressive social systems. The character of Randle McMurphy embodies the idea that madness can be a source of strength, challenging the strict control of the mental institution and inspiring other patients to reclaim their own identities. His eccentric behavior highlights the thin line between sanity and insanity in a conformist society.

The quote suggests that extreme madness may empower an individual, allowing for a kind of resilience that can defy societal expectations. In the context of the story, McMurphy's 'craziness' not only brings him strength but also encourages those around him to confront their own fears and limitations, ultimately demonstrating the complexity of mental health and personal freedom. Kesey's narrative invites readers to reconsider their perceptions of normality and the concept of strength in vulnerability.
