In this book, Marsh offers a new way of reading the theology of Dietrich Bonhoeffer, a Christian theologian who was executed for his role in the resistance against Hitler and the Nazis. Focusing on Bonhoeffer's substantial philosophical interests, Marsh examines his work in the context of the German philosophical tradition, from Kant through Hegel to Heidegger. Marsh argues that Bonhoeffer's description of human identity offers a compelling alternative to post-Kantian conceptions of selfhood. In addition, he shows that Bonhoeffer, while working within the boundaries of Barth's theology, provides both a critique and redescription of the tradition of transcendental subjectivity. This fresh look at Bonhoeffer's thought will provoke much discussion in the theological academy and the church, as well as in broader forums of intellectual life.
