I really enjoy getting new books, but I also value my library. I don't feel like I have to go out and buy every book that I think I might ever look at. So for instance in last week's "Books I've been Reading This Week" post (here), one of those I was skimming through from the library was Jaroslav Pelikan's Christianity and Classical Culture: The Metamorphosis of Natural Theology in the Christian Encounter with Hellenism (sounds like the week for long subtitles). This is Pelikan's Gifford lectures, and I think I've decided that I'd like to start intentionally collecting Gifford books. So, trolling the used book sites, I found a nice copy for the right price.
Then, very reasonably, I picked up a used copy of Etienne Gilson's Reason and Revelation in the Middle Ages (no subtitle).
