"The definition of insanity as well as the power to define insanity are questioned"
This quote is from page 406 of "Censored Books", and unfortunately the Google book preview does not include the page that shows which of the editors/authors wrote this section on Ken Kesey's "One Flew Over the Cuckoo's Nest". I need to know which author to credit as I need to use this quote for my coursework, and referring to all three every time would not be practical nor professional of my coursework.
Anyone who possibly has this book, or access to the knowledge to find which author wrote this quote, would be greatly appreciated.
EDIT: Here is the exact book from the Google preview.
