Jean-Luc Marion is a French philosopher and Roman Catholic theologian. Marion is a former student of Jacques Derrida whose work is informed by patristic and mystical theology, phenomenology, and modern philosophy. Much of his academic work has dealt with Descartes and phenomenologists like Martin Heidegger and Edmund Husserl, but also religion. God Without Being, for example, is concerned predominantly with an analysis of idolatry, a theme strongly linked in Marion's work with love and the gift, which is a concept also explored at length by Derrida.
