To my mind, David Lyle Jeffrey is one of the finest Christian intellectuals around.  He currently teaches at Baylor University.  His scholarship is first-rate, and he is true Christian gentleman.  I have been reading him since I first started to wrestle with questions of the nature of language, and how Christians might think rightly about the nature of language.  I highly recommend his books, including People of the Book and Houses of the Interpreter.  I was listening today to a lecture he gave a few years ago on the current state of the discipline of English literature, and how English as a discipline will continue to flounder as long as it continues to drift from its historical moorings, where it was anchored to the Christian faith.  To any and all persons interested in the confusion in the contemporary academy, and to anyone simply interested in such issues, I would recommend this talk highly.  Here is a link to Jeffrey's talk on i-tunes.  It should be talk #37 on this list.
