“The Hobbit is merely the adaptation to children of part of a huge private mythology of a most serious kind: the whole cosmic struggle as he sees it but mediated through an imaginary world. The Hobbit’s successor [The Lord of the Rings], which will soon be finished, will reveal this more clearly. Private worlds have hitherto been mainly the work of decadents or, at least, mere aesthetes. This is the private world of a Christian. He is a very great man. His published works (both imaginative & scholarly) ought to fill a shelf by now: but he’s one of those people who is never satisfied with a [manuscript]. The mere suggestion of publication provokes the reply ‘Yes, I’ll just look through it and give it a few finishing touches’ – wh. means that he really begins the whole thing over again.”
C.S. Lewis, in a letter to Charles A. Brady, October 29 1944.
