Abstract
This paper takes the dichotomy between “exclusive” and “inclusive” positivism and applies it by analogy to natural-law theories. With John Finnis, and with Beyleved and Brownsword, we have examples of “exclusive natural-law theory,” on which approach the law is valid only if its content satisfies a normative monological moral theory. The discourse theories of Alexy and Habermas are seen instead as “inclusive natural-law theories,” in which the positive law is a constitutive moment in that it identifies moral rules and specifies their meaning. The article argues that inclusive theories of natural law are better suited to expressing an authentic “republican” attitude.*In the seed of the city of the just, a malignant seed is hidden, in its turn: the certainty and pride of being in the right.
