This is a long, hard slog through the logical proofs for and against atheism. Only read this if you can read page after page of formal logic proofs without your eyes crossing. Otherwise you're better off sticking with Dennett, Harris, Dawkins and their equivalents.

That's a little more harsh than needed, as this really is one of the best formal defenses of atheism, and I'm glad I read it (I'll probably return to it at some point). It just won't keep the interest of most people.
