On the Unities of Law, Practical Reason, and Right: Foundations of the Unity of Reason beyond the Plurality of Knowledge and of Normative Orders

The problem addressed in this article is the relationship between law and morality. It is asked (1) to what extent law and morality are connected and separated and (2) since when has it been so. To the extent that law and morality are distinct normative orders, it is asked (3) whether they rule exactly the same behaviors or whether each order rules dierent kinds of behaviors. If they rule at least some of the same behaviors, it is asked (4) whether there can be antinomies (contradictions) between them. If there are an- tinomies, it is asked (5) whether the antinomies are only apparent (prima facie) and are therefore mistakes of human reason, or are definite and real. If the antinomies are apparent or real, it is asked (6) whether law or morality prevails (or should prevail) in the case of an antinomy. If one of these prevails, it is asked (7) whether this is always so, or whether law sometimes prevails (and should prevail) over morality and vice versa. In the case of existing coherence or at least solvable antinomies between law and morality, it is asked (8) whether the consequent achieved unity of practical reason is a specifically moral unity and whether it is a matter of cognition, of institutionalization, of individual or collective construction, or of consensus.
