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 <i>An Elementary Christian Metaphysics</i> 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.
