A Kantian Solution to the Problem of the Conceptual Origins of the Normativity of Law

I propose an interpretation of the concept of legal validity as a Kantian category so that the question about the ultimate foundation for the validity of a legal order does not arise, since it makes sense to ask about the reasons for the validity of specific legal norms, but it is illegitimate to apply this concept to the totality of norms of a legal system. Thus, the basic norm is not to be conceived as the final grounding of legal validity but as the ultimate transcendental condition for the cognition of it. I also reformulate the Kelsenian concept of effectiveness in terms of the apriori condition that guarantees the existence of legal systems as the objects of study of the science of law.
