Please answer this: I know that the answer to the question "Why are there not more biographies on Whitehead?" is in "The two volume biography of Whitehead by Victor Lowe is the most definitive presentation of the life of Whitehead. However, many details of Whitehead's life remain obscure because he left no Nachlass; his family carried out his instructions that all of his papers be destroyed after his death. 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. This led to Lowe himself remarking on the first page of Whitehead's biography, "No professional biographer in his right mind would touch him."". Can you tell me what it is?

input question: I know that the answer to the question "If I were to follow this train of thought, what should I be cognizant of?" is in "The "Neo-Eriksonian" identity status paradigm emerged in later years[when?], driven largely by the work of James Marcia. This paradigm focuses upon the twin concepts of exploration and commitment. The central idea is that any individual's sense of identity is determined in large part by the explorations and commitments that he or she makes regarding certain personal and social traits. It follows that the core of the research in this paradigm investigates the degrees to which a person has made certain explorations, and the degree to which he or she displays a commitment to those explorations.".
