Impossible God introduces Derrida's theology for a new generation interested in Derrida's writings and in the future of theology, and clarifies Derrida's theology for those already familiar with his writings. Derrida's theological concerns are now widely recognised but Impossible God shows how Derrida's theology takes its shape from his earliest writings on Edmund Husserl and from explorations into Husserl's unpublished manuscripts on time and theology. Rayment-Pickard argues that Derrida goes beyond both the nihilism of the 'death of God' and the denials of negative theology to affirm a theology of God's 'impossibility'. Derrida's 'impossible God' is not another God of the philosophers but a powerful deity capable of wakening us into faith, ethical responsibility and love. Showing how central theology has been to Derrida's philosophy since the beginning of his career, Impossible God presents an accessible study of a neglected area of Derrida's writing which students of philosophy and theology will find invaluable.
