“Dreamer of Dune: The Biography of Frank Herbert” by Brian Herbert, his eldest son, who does not say the author of Dune had multiple personality

Comment: This 576-page biography (1) includes an index, which does not reference “split personality,” “multiple personality,” or “dissociative identity “disorder,” either for Frank Herbert, Frank Herbert’s novel, Dune, or even Frank Herbert’s earlier novel, The White Plague, in which the protagonist has explicit multiple personality disorder (see recent posts).

Of course, if an author did have “multiple personality trait,” my term for a nonclinical, creative version of the disorder, the author would neither be nor look mentally ill, and would not exhibit behavior that the average person would recognize as a split personality; except, possibly, in an emotional crisis, or in response to questions about memory gaps, pseudonyms, or episodes of behavior that were atypical for that person.
