Even if you haven't been reading along with Trevin and I, I still commend this series of posts on Chesterton's book to you. The latest is over at his blog, where you can also see the list of previous posts as well.
Trevin has a keen eye for what matters, and the conversation that this book has provoked has been....shall we say timely?
I commend it to you, then, and look forward to dialoguing more in the comments there.
And do let me know if you have interest in more of this sort of thing. I've recently been reading and rereading Augustine's City of God and have thought about a book-by-book conversation about it through the fall--if, that is, the interest was there.
