One of the professors at school referred us students to an address given at Harvard a while back (1978). Solzhenitsyn was a Russian who lived during the Communist times, lived at a labour camp for years, and was finally exiled because of his views. I believe that he became a Christian. He died just last year.
Here's a very short version of his speech and here's the whole shebang. It's a fascinating critique of Western society, written from a Christian perspective and also from one who grew up as a Russian communist.
Thanks for the link, Brian! (In case you're reading this.)
