The question of how politics and ethics connect, if at all, in our societies is crucial, especially given today’s socio-economic and geopolitical challenges. Commentators have sought answers in Kant’s texts: the relation between the Categorical Imperative (CI) as the fundamental principle of ethics, and the Universal Principle of Right (UPR) as the fundamental principle of politico-legal norms, has been variously interpreted as one of simple dependence, simple independence, or complex dependence. Recent interpretations increasingly agree that Kant was not a simple independentist. However, questions persist about the philosophical significance of Kant’s account, specifically whether certain aspects of his thought inconsistently commit him to simple independentism. One aim of this chapter is to illustrate this critical strategy starting from a specific interpretation of the UPR. It is argued that, although robust, this interpretation is not the most accurate. While this strategy opens new avenues for further objections to Kant, the chapter concludes that the complex dependentist reading is philosophically the most convincing to date.
