I'm currently reading Phillip K Dick's A Clockwork World and he drops an Eriugena quote at the begging of most chapters. They are all pretty profound and it's really making me want to read some of hist stuff.

Also, for anyone who hasn't read it, really interesting book, and one of PKD's more theological ones. Time is working in reverse and the dead are literally rising from the grave, living out their lives from old to youth, and eventually having to find unbirth mothers to return to zygotes and blink back out of existence. Good, relatively quick (~200 page) read for anyone looking for an interesting mix of sci-fi and theology.
