Joseph Owens presents an introduction to metaphysics designed to develop in the reader a habitus of thinking. Using original Thomistic texts and Etienne Gilson's interpretation of St. Thomas Aquinas, Owens examines the application of metaphysical principles to the issues that arise in a specifically Christian environment. From a starting point of external, sensible, non-human beings, An Elementary Christian Metaphysics focuses in the questions of existence and the nature of revealed truths. Following his historical introduction to metaphysics, Owens provides a general investigation of the first principles and causes of being, and a study of knowledge and of the divine nature and attributes in light of natural reason.
