This book really is a stunning accomplishment. Dembski is a real master at organizing a tremendous amount of material and getting straight to the point. The result can be slow going for the non-specialist like myself, but very rewarding.
Despite all the desperate attempts to silence ID, they are not going away. Chapter 41 (Peer Review) alone is worth the cover price -- it shows the lengths to which the neo-Darwinian establishment will go to belittle and marginalize any creative attempts to question them. Whatever you think of ID and the debates, this chapter will interest anyone who cares about free speech and about the growing illiberal nature of the academy.
Dembski, like several others in the ID movement (see Jonathan Wells, or some of the contributors to Mere Creation), is one of the great intellectual athletes of this generation: a Ph.D. in math from Chicago, another Ph.D. in philosophy; graduate and post doc degrees in theology (Princeton Seminary), computers, biology, etc. from places like Princeton U. and MIT, with a huge corpus of writings. He's a renaissance man who really is able to master several disciplines and show connections between them. That makes his books so fun and engaging even for people without special interest in science.
Of all his books, I found this one probably the most engaging, and most able to help me see how ID ties into a larger framework of worldview issues.
