Fifth, I am very impressed that you would even know this about Herbert. I read a lot of books (many years ago), but unless I had read them very recently, I don't think I would recall this detail at all.
I didn't remember the detail, heh. I bought a used hardcover of Dune some months ago, planning to study its story structure. Haven't quite done that. But I did think the thoughts were simply italics without speech tags–that's what I remembered–until a month or so ago when I happened to look for those thoughts in the book again and realized my memory had been faulty.
