Abstract

Taking as a starting point the assertion of an ambiguity in the Lutheran tradition's assessment of reason, the essay argues that the Kantian unreserved confidence in reason is criticised in Bonhoeffer. Based upon a Christological understanding of reason, Bonhoeffer endorses a view of reason which is specifically Christian and yet maintains a universality. With a focus on Bonhoeffer's Ethik as the hermeneutical key to his theology, Bonhoeffer's notion is also discussed in light of contemporary Christian ethics. In this part it is particularly the role of reason within a public discourse which is treated in the essay. Here it is argued that Bonhoeffer may be appropriated in attempting to outline a Christological ontology of reason holding essential implications for the sources and conditions of public discourse.
