I have to say that the theory is very compelling that the 7 planets represent the themes of the books. It's amazing that no one had picked up on it before until one author had a flash of insight while simultaneously reading several of his books.

It makes you wonder whether Lewis planned this before he wrote the series or if he was just so steeped in the medieval cosmology that the structure just flowed naturally and subconsciously for him.
