What is metaphysics? Metaphysics: A Basic Introduction in a Christian Key gives a simplified answer to this daunting question. Born under the shadow of the Parthenon by Aristotle and his contemporaries, metaphysics eventually enjoyed its heyday in the medieval era and is finding a resurgence today in modernity. This book explores the perennial question of being and its uptake in the world of Christian theology. Donald Wallenfang leads the reader through five navigable chapters that feature the most basic themes of metaphysics: the question of being, first principles, causality, cosmology, and morality. The abstract tendencies of metaphysics are brought down to earth with reference to the gospel of Jesus and the relevance of metaphysics for daily living. Altogether, the reader will be inspired to think toward the whole by asking questions that penetrate beneath the surface of things. Beauty, truth, and goodness will be unveiled to the degree that we accompany Jesus the metaphysician along his itinerary of being given.
