I read "Method" in my first corse for my Ph.D. in theology at Marquette University in 1984.  It was a difficult book to get through, but well worth the time and effort. I wish I still had my copy, but it was give to a university library which badly needed some decent books for its theology secton.  I hope those who have withdrawn it for research or reading purposes have gotten as much ot of it as I did.
