Mystery for Psychology and Literary Criticism: Fiction writers—even professors of literature or creative writing—rarely write books that explain their work.

It is a tacit assumption of most literary theories, literary critics, and psychologists that most novelists, playwrights, and poets understand their creative process and the things they write.

And maybe they do understand it. But what is the evidence? Are there books, written by authors, themselves, that prove it?

If you know of any such books, please cite them, and submit your comment.
