In the Preface to his recent study, The Trespass of the Sign, Kevin Hart writes of his “abiding interest in bringing deconstruction into conversation with Christian theology” (p.x). At the heart of his account of how the strategy of deconstruction can illuminate theology is the distinction between the reality of God and the concept of God. In this note I wish to draw attention to the importance of the distinction Hart has made for all future considerations of the relationship between negative and positive theology.
