Their important exegetical and philosophical disagreements notwithstanding, Pauline Kleingeld and Marcus Willaschek, on the one hand, and Alyssa Bernstein, on the other, seem to agree that Kant’s Categorical Imperative transcends the contemporary dichotomy between moral realism and ethical constructivism. My contribution is an attempt to further elaborate on the third, unique, conceptual option that they have identified. I employ the notion of an “enabling condition,” introduced in epistemology and action theory by Jonathan Dancy, in order to show that the Categorical (...) Imperative enables action and is enabled by action. The Categorical Imperative (as distinct from specific categorical imperatives and moral laws) is discussed as a structural, but still normative, coherence and consistence norm of practical reasoning. As such it is two things at the same time, namely, first, the most fundamental normative background condition of practical deliberation, choice, and action. Second, however, the mutual enabler-enablee-relationship between action and Categorical Imperative points in the other – “not-so-Kantian” – direction as well: individual practical deliberation, understood as the mundane phenomenon that penetrates the lives of agents, is the (existence) condition that enables the Categorical Imperative in normatively-structured action.
