The Facticity of Kant's Fact of Reason

Abstract

It is argued that the key to understanding the Doctrine of the Fact of reason lies in clarifying what Kant meant by a fact for moral practice. It is suggested that the facticity of the Fact of Reason must be understood in both a noetic and a performative aspect. Dietrich Henrich's interpretation is discussed, and it is argued that it risks reducing the Fact of Reason exclusively to its noetic function in moral ontology, and that it ignores the fact that this is a doctrine of self-discovery, not of self-constitution.
