"Everybody believes in psychiatry; it's supposed to be for our own good. Let psychiatry prove that anybody has an illness, and I'd concede, but there is no physical proof"

This quote by Kate Millett speaks to the lack of physical proof for mental illness. She is recommending that while everybody believes in psychiatry, there is no physical proof that anybody has a disease. This indicates that mental disorder is not a tangible, physical condition, however rather a subjective experience. Millett is challenging the concept that mental disorder is a genuine, diagnosable condition, and rather recommends that it is a social construct. She is recommending that mental illness is not something that can be shown, and that it is instead a subjective experience that is shaped by our culture and society. This quote talks to the need for more research into mental disorder, and the need to better understand the subjective experience of mental illness.
