There's a good series of posts just started on William M Briggs' Blog. He's working his way through Peter Kreeft's book Summa Philosophica . As his title implies, Kreeft is adopting the style of St Thomas Aquinas to deal with some philosophical question. I suppose it is surprising that no one ever thought of doing this before - after all, if it's good enough for the Angelic Doctor & theology, it's bound to be a wise choice for any number of other topics ... especially philosophy.

I'd heard of Kreeft's book before, but hadn't looked into it. After Briggs' 'taster' I felt impelled to go and order the book. And I can't wait for it to arrive!
