I want to know the answer to the following question:
What did Whitehead believe in so profusely that it was difficult to write a biography on him?
All the background I'm provided with is that "Additionally, Whitehead was known for his "almost fanatical belief in the right to privacy", and for writing very few personal letters of the kind that would help to gain insight on his life.". Is that enough to answer the question?
Answer: yes
