Thanks to Noel/Steve for this interview of Douglas Gresham, C.S. Lewis' adopted son who is writing a book about his father. Interesting view on Lewis as more than just a smart guy.Here's an excerpt:

Americans have latched on to C. S. Lewis, and yet here's a guy who was a chain smoker, who liked his pints, who told ribald jokes, and in general, wouldn't fit what we think of as the "typical evangelical." And yet we've all wrapped our arms around him. Why is that?

Gresham: One of the reasons is that through the—if you can excuse the expression—the bullshit that has come to be taken so seriously in American Christianity, through all of that, they can still see the essential truth that Jack represented. The problem with evangelical Christianity in America today, a large majority of you have sacrificed the essential for the sake of the trivial. You concentrate on the trivialities—not smoking, not drinking, not using bad language, not dressing inappropriately in church, and so on. Jesus doesn't give two hoots for that sort of bullshit. If you go out and DO Christianity, you can smoke if you want, you can drink if you want—though not to excess, in either case.

But I think that even past the trivialities, many evangelical Christians can see the ultimate truth to what Jack wrote. I think that's why he's so popular.
