Kant's Critique of Pure Reason denies »knowledge« in order to make »room for faith«. But how is this room to be shaped? According to Kant, by a »rational belief« which states the truth of some theoretical propositions only from a »practical point of view«, while for the theoretical use of reason these propositions have to remain undecided. Burkhard Nonnenmacher subjects Kant's determination of the relationship of faith and reason to a thorough analysis by explicating its relationship to the »Architectonic of Pure Reason«. In this context, Kant's central conclusions on fundamental theology are developed alongside his main decisions on dogmatics, with the latter paying special regard to Kant's Religion within the Boundaries of Mere Reason. The study calls into question whether Kant's determination of the relationship between sin, grace and justification as well as his positions concerning Christology, Ecclesiology and Eschatology have to be regarded as being without any alternative. Furthermore, it seeks methodological problems in Kant's approach and searches for the significance of these for systematic theology today.
