Kundera is one of my faves -- have you read any others? I think _Unbearable..._ is the best, but The Book of Laughter and Forgetting is up there, too.
The Problem of Pain is fabulous, much like everything else Lewis has written. I'm sure you'll enjoy it!
Just as a side note, how are you all getting the italics? Do I need to not use the Rapid Response Box? Just wondering...
