I recently listened to an audio version of Jonathan Edwards' sermon "A Divine and Supernatural Light" (courtesy of the Christian Classics Ethereal Library). Though the style is not contemporary, Edwards had a broad range of insights into human psychology, despite the popular caricature of him as a fire-and-brimstone preacher. Here's a nice page of links to his numerous works.

Though this particular sermon isn't easy going, it's gotten me thinking about what the Scriptures have to say about knowledge, especially as it pertains to learning and motivation for Christlikeness. I've started an OPML outline to record some of this thinking, though be warned it's a work in progress. If you can't handle OPML, you may prefer less-aesthetic-but-more-readable HTML version.
