Question: the one who flew over the cuckoo's nest themes?
Answer: The main themes in One Flew Over the Cuckoo's Nest are insanity, power, and gender. Insanity: The novel questions the value of insanity as a label: McMurphy fakes his insanity, Harding's latent homosexuality is no longer considered a mental illness, and Billy, though suicidal, voluntarily committed himself.
