Does man fit into the world as a moral actor? In Kant's earlier approaches, only faith catering to the needs of human practice remained to supply an answer to this question. In the "Critique of Judgment", though, Kant attempts to show that the conviction concerning the existence of a morally compatible world can indeed be independently justified - namely from aesthetics and biology. The author first provides a systematic analysis of Kant's problem: What motivates the search for such a transition between theory and practice and what can be considered a satisfactory solution? He then proposes an innovative reading of the role of biology in the transition argument: It is not to be understood as a positive contribution, but as an obvious objection to the argument pursued in the first place. This sheds new light in particular on the antinomy of teleological judgement.
