Paul Helm is a distinguished philosopher, with particular interests in the philosophy of religion. His work covers some of the most important aspects of the field as it has developed in the last thirty years with particular contributions to metaphysics, religious epistemology, and philosophical theology. In celebration of Helm's life's work, Reason in the Service of Faith brings together a range of his essays which reflect these central concerns of his thought. Over thirty of Helm's selected essays and four unpublished articles are gathered into five parts: Metaphilosophical Issues; Action, Change, and Personal Identity; Epistemology; God; and Creation, Providence, and Prayer. The volume is prefaced with a short editorial introduction, and ends with an extensive bibliography of Helm's published works. Demonstrating the important connection between Helm's theological and philosophical interests across his body of work, this collection is a remarkable resource for scholars of religion, philosophy, and theology.
