Thanks. I just looked up Tolkien: A Celebration at Amazon.com. The book by Bradley Birzer looks interesting, as well, and was co-authored by Joseph Pearce.
The Platonist/Augustinian themes of the Lord of the Rings are obvious, as GOPcapitalist said. I'm just surprised more readers don't bring that up.
I don't really agree. If you know Tolkien's paradigm for all of Middle Earth, it is not platonic at all -- and the one ring is not really like Plato's at all. I think the connection with Augustine at the end is a little more solid, but only because both Tolkien and Augustine share a Christian worldview and theology, not because Tolkien was imitating or borrowing from Augustine
