Here is an interesting article on spirituality and scholarship from an very interesting volume. I don't say whether I agree or disagree but it is definitely food for thought. See especially pages 159-160.
[By the way - the author of the article was in my brother's high school class. I remember reading in their yearbook that he was so smart that he could play chess against six people simultaneously while blindfolded and win [or something to that effect]. That is smart:-)].
