The two standard interpretations of Kant’s view of the relationship between external freedom and public law make one of the terms a means for the production of the other: either public law is justified as a means to external freedom, or external freedom is justified as a means for producing a system of public law. This article defends an alternative, constitutive interpretation: public law is justified because it is partly constitutive of external freedom. The constitutive view requires conceiving of external (...) freedom in a novel, second-personal way, that is, as an irreducibly relational norm. (shrink)
