"Rethinking Islam in the Contemporary World" by Carl Ernst

I am reading Carl Ernst's book "Rethinking Islam in the Contemporary World". Here's the Preface.

For some reason, when the book was released in the UK by the Edinburgh University Press (which is the edition I am reading), the original title Following Muhammad (as seen on the book cover on he left) was dropped, leaving the subtitle as the title.

Ernst has also compiled a web page which contains updated links to Internet sources cited in the book, organized by themes.
