Abstract

In his 1960 paper “The concept of moral insight and the Kantian doctrine of the Fact of Reason” (introduced and translated in french by Laura Tavernier), Dieter Henrich argues that Kant’s doctrine of the Fact of Reason—according to which pure reason can not theoretically anticipate or ground the possibility of its practical use—does not betray a lack of systematicity, as post-Kantians reproached it to Kant. After the repeated failures of his own attempts to deduce moral insight from theoretical reason in the “silent decade”, Kant eventually acknowledges that the moral law and our awareness of it cannot be logically derived from a higher principle. The Kantian doctrine of the Fact of Reason thus remains faithful to the phenomenon of moral insight, the paradoxical knowledge of the good, and offers a methodologically adequate answer to the problem that D. Henrich considers to be at the foundation of metaphysics: Kant thinks of a unity of the theoretical and the practical reason that does not imply any derivation of one from the other, nor any subsumption of the two under a unifying principle.
