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.
