Thesis Statement / Essay Topic #1: The Author as Novelist and Participant-Observer

One Flew Over the Cuckoo’s Nest is a novel, and author Ken Kesey informed the book with his experiences as an employee in a mental institution; such direct observation creates a sense of authenticity that might not otherwise be achieved. Ken Kesey went one step further however, by subjecting himself to the same treatments that the patients in the mental institution experienced, receiving electroshock therapy and taking psychotropic medication. Although going as far as he did as a participant-observer-novelist is controversial, it makes One Flew Over the Cuckoo’s Nest engaging and credible. As a result, the author is able to compel the reader to feel empathy for the characters.

Thesis Statement / Essay Topic #2: The Theme of Authority in One Flew Over the Cuckoo's Nest

Although the setting of One Flew Over the Cuckoo's Nest is limited to the interior of the ward of a mental institution, the reader does not meet any significant authority figures other than Nurse Ratched. Nurse Ratched is a severe, overbearing individual who strives to maintain a rigid hierarchical structure that was typical of mental institutions at the time when Ken Kesey wrote One Flew Over the Cuckoo’s Nest. While the reader never really catches a glimpse of Nurse Ratched outside of her buttoned-up authority role, one might analyze her character and her behavior, interpreting both as a defense mechanism. Despite the guise of absolute control, Nurse Ratched actually feels out of control inside, threatened by the patients because they confront her with the possibility that she may not be so well herself.

Thesis Statement / Essay Topic #3: Character Density in One Flew Over the Cuckoo's Nest

One of the most fascinating aspects of Ken Kesey’s One Flew Over the Cuckoo’s Nest is the fact that the novel is populated with an unusually large number of characters for the genre. There are more than 30 characters, major and minor, each of whom adds to the plot and makes the subject more meaningful. Although it may be challenging to keep up with this large cast of characters, each seems essential to the novel. The function of each character is to highlight a certain aspect of society that Kesey found problematic at the time. While the treatment of the mentally ill was obviously one aspect of society Kesey found problematic, there were many others, including racism, sexism, and homophobia.

Thesis Statement / Essay Topic #4: Concepts of Care

There are three nurses who play significant roles in One Flew Over the Cuckoo’s Nest: the despotic Nurse Ratched, the religious and self-involved Nurse Pilbow, and a compassionate, effective nurse who the reader only comes to know as the Japanese Nurse. Each of these three nurses offers a very different type of care to the patients in the mental institution. In light of what is now known about the effective and humane treatment of people with mental illnesses, it is the Japanese Nurse who offers the most compassionate care. The fact that the Japanese nurse remains a marginal figure compared to the other two and the fact that she remains anonymous, without a real name, reinforces Kesey’s criticism of the mental health system at the time during which he was writing the novel.

Thesis Statement/Essay Topic #5: The Topic of Race in One Flew Over the Cuckoo’s Nest

Although the reader is entering a world that is clearly not normal, located as it is in a mental institution, there are varying degrees of dysfunction and disorder in One Flew Over the Cuckoo’s Nest. Characters who are not Caucasian, whether patients or “normals,” are portrayed as particularly depraved and even sub-human. Kesey did not seem to believe that this was, in fact, the case. Rather, he is exaggerating the characteristics that were attributed to minorities during the time to point out how pervasive, ridiculous, and damaging racism could be.

“…a little Jap nurse came to take us into the Nurses' Station….The nurse…undid our cuffs and gave McMurphy a cigarette and gave me a stick of gum. She said she remembered that I chewed gum…She picked up one of his hands in both of hers and turned it over and salved his knuckles” (233).
