james.rogerson posted in this thread (http://www.suscipedomine.com/forum/index.php?topic=14140.0) about the dissertation linked to above. A lot of folks mentioned interest. That thread is a few years old now and I wonder if anyone had the chance to read the PDF or track down and read the book it served as the basis for? (Or the Triumph compilation book?)
I'll let you know when I've read it.
I've read Bozell's "Letter to Yourselves" twice now and I think it magnificent and as applicable now as it was then.
