In a comment at the end of the Religion and Science post, Brandon of Siris mentions Peter King as a source for discussions of Anselm’s ontological argument. If you’re interested, here’s a link to his encyclopedia entry on Anselm, and this paper discusses the logic of the argument in more detail.
Readers of this blog might find some other papers by King more interesting, though. He’s written pretty extensively on medieval philosophy of mind and language. Since we’ve already mentioned Anselm, you can start with his paper “Anselm’s Philosophy of Language.” After that, you should check out “Between Logic and Psychology: Jean Buridan on Mental Language,” Duns Scotus On Mental Content,” “Rethinking Representation in the Middle Ages,” “Scholastisism and the Philosophy of Mind: The Failure of Aristotelian Psychology,” and finally, Why Isn’t The Mind Body Problem Medieval?.”
I haven’t read all of them yet, but what I have read I’ve really enjoyed, despite my near complete ignorance of medieval philosophy. I might try to say something about a couple of the papers later, because some of the issues discussed are ones that I still deal with on a daily basis.
