With Kant’s conception of organisms as “natural ends” nature and freedom are represented as harmoniously cohering with each other thereby giving us a special reassurance of reason’s causal efficacy in nature. For Kant, in order to make organic formations intelligible, we must represent the rule of their organization as reciprocal causality. I contend that this rule of reciprocal causality serves as a schema-analogue of reason’s Idea of absolute freedom. Moreover, I proceed to show that the antinomial conflict of teleological judgment is a conflict between two perspectives on nature: theoretical (scientific) in the thesis and practical in the antithesis. Therefore, the solution to the antinomy does not merely offer a justification for the explanatory compatibility of mechanical and teleological explanation in our representation of a single organic formation but also leads to a view of the world according to which the theoretical and the practical representations of nature “must cohere.”
