Norman Kretzmann expounds and criticizes St. Thomas Aquinas's natural theology of creation, which is `natural' (or philosophical) in virtue of Aquinas's having developed it without depending on the data of Scripture. The Metaphysics of Creation is a continuation of the project Kretzmann began in The Metaphysics of Theism , moving the focus from the first to the second book of Aquinas's Summa contra gentiles .
It's a fine piece of scholarship, but it's a bit too analytical for my taste. I would have prefered more of a historical presentation, but a lot of the times the author is evaluating Aquinas by modern philosophical standards. Again, not bad, but not excellent.
