I am one of those people who tend to think of favorite writers as "friends." On rare occasion (like the time Henri Nouwen bought Mark Roberts and me pizza and beer) I get to meet these literary friends. Mostly, I don't. Many have been long dead. But the very point of having literary friends is that the impact of their thoughts and their lives linger long.
C. S. Lewis is certainly, in those terms, a friend to many. One of my "real" friends, Craig Williams, spent a summer studying Lewis while on sabbatical. He even read original manuscripts in Lewis' own hand. Today, let me encourage you to check out Craig's series on "Lewis and Post-modernism" for a delightful and thought provoking introduction to TWO of my friends, Craig and Clive.
