I just finished reading Bernard Lewis' I'm Right, You're Wrong, Go To Hell from the May issue of The Atlantic. Interesting, but nothing really new, if you read his stuff. Very similar to his new book Crisis in Islam which, I think, was an expansion of an Atlantic article. These guy knows how to market his stuff!
But anyway, if you don't know his stuff, this is an interesting comparison of Christianity and Islam and their views of history and their interaction over that history--particularly in regards to issues of toleration.
