Jean-Luc Marion is one of the leading Catholic thinkers of our time: a formidable authority on Descartes and a major scholar in the philosophy of religion. This book presents a concise, accessible, and engaging introduction to the theology of Jean-Luc Marion. Described as one of the leading thinkers of his generation, Marion's take on the postmodern is richly enhanced by his expertise in patristic and mystical theology, phenomenology, and modern philosophy. In this first introduction to Marion's thought, Robyn Horner provides the essential background to Marion's work, as well as analysing the most significant themes for contemporary theology. This book serves as an ideal starting point for students of theology and philosophy, as well as for those seeking to further their knowledge of cutting-edge thinking in contemporary theology.
