This article defends a non-positivist theory of law, that is, a theory that accepts the necessary connection between legal validity and moral correctness by reference to the work of John Finnis. It begins with the dual nature of law as comprising both a real or factual dimension and an ideal dimension. Important examples show that at least some kinds of moral defect can deprive law of validity from the perspective of a participant in the legal system. The nature of the connection between moral defectiveness and legal defectiveness is specified in terms of three possibilities: exclusive non-positivism, in which all cases of moral defect render law invalid; inclusive non-positivism, in which moral defect renders law invalid in some cases; and super-inclusive non-positivism, in which legal validity is not affected by moral defect at all. The paper argues for inclusive non-positivism as exemplified by the Radbruch Formula, according to which extreme injustice is not law, and which strikes the right balance between the ideal and real dimensions of law, against John Finnis’s account, which can be seen as an example of super-inclusive non-positivism, although his most recent work has tended towards the inclusive version.

In the debate between positivism and non-positivism the argument from relativism plays a pivotal role. The argument from relativism, as put forward, for instance, by Hans Kelsen, says, first, that a necessary connection between law and morality presupposes the existence of absolute, objective, or necessary moral elements, and, second, that no such absolute, objective, or necessary moral elements exist. My reply to this is that absolute, objective, or necessary moral elements do exist, for human rights exist, and human rights exist because they are justifiable.

The central argument of this article turns on the dual‐nature thesis. This thesis sets out the claim that law necessarily comprises both a real or factual dimension and an ideal or critical dimension. The dual‐nature thesis is incompatible with both exclusive legal positivism and inclusive legal positivism. It is also incompatible with variants of non‐positivism according to which legal validity is lost in all cases of moral defect or demerit (exclusive legal non‐positivism) or, alternatively, is affected in no way at all by moral defects or demerits (super‐inclusive legal non‐positivism). The dual nature of law is expressed, on the one hand, by the Radbruch formula, which says that extreme injustice is not law, and, on the other, by the correctness argument, which says that law's claim to correctness necessarily includes a claim to moral correctness. Thus, what the law is depends not only on social facts, but also on what the law ought to be.

The argument of this article is that the dual-nature thesis is not only capable of solving the problem of legal positivism, but also addresses all fundamental questions of law. Examples are the relation between deliberative democracy and democracy qua decision-making procedure along the lines of the majority principle, the connection between human rights as moral rights and constitutional rights as positive rights, the relation between constitutional review qua ideal representation of the people and parliamentary legislation, the commitment of legal argumentation to both authoritative and non-authoritative reasons, and the distinction between rules as expressing a real “ought” and principles as expressing its ideal counterpart. All of this underscores the point that the dual nature of law is the single most essential feature of law.

In this paper the author criticizes the way Robert Alexy reconstructs the relationship between legal and practical reasoning. The core of Alexy's argumentation (Alexy 1978) is considered the claim that legal argumentation is a “special case” of general practical discourse. In order to question this claim, the author analyzes three different types of argument: (1) that legal reasoning is needed by general practical discourse itself, (2) that there are similarities between legal argumentation and general practical discourse, (3) that there is a correspondence between certain types of argument in general practical discourse and in legal argumentation.**

Ever since Hegel made poignant the difference between morality and ethical life (“Sittlichkeit”), philosophical discourse in the traditions that developed subsequently, up to and including the Frankfurt school, has oscillated between those poles. This paper starts out with a short exposition of autonomy as one of the few large-scale innovations in the history of philosophy and then proceeds to discuss Hegel’s concept of “Sittlichkeit” and the objections to be raised against it from a Kantian point of view. Political theory, however, has to move beyond pure normativism and consider actual social relations of power, as Marx disclosed. Mapping out this winding trajectory from Kant to Marx provides some perspective that may be illuminating for challenging present-day issues.

The main thesis of this article is that Kant’s concept of law is a non-positivistic one, notwithstanding the fact that his legal philosophy includes very strong positivistic elements. My argument takes as its point of departure the distinction of three elements, around which the debate between positivism and non-positivism turns: first, authoritative issuance, second, social efficacy, and, third, moral correctness. All positivistic theories are confined to the first two elements. As soon as a necessary connection between these first two elements and the third element, moral correctness, is established, the picture changes fundamentally. Positivism becomes non-positivism. There exist two kinds of connections between law and morality: classifying and qualifying connections. This distinction stems from different sorts of effects that moral defects give rise to. A classifying connection leads to the loss of legal validity, whereas a qualifying connection leads only to legal defectiveness. In Kant’s theory of law both connections are found. The qualifying connection is conspicuous throughout Kant’s theory of law, whereas the classifying connection, by contrast, is rare and well hidden. This will suffice to consider Kant as a representative of inclusive non-positivism.

This article offers an overview of the difficulties in Robert Alexy’s idea of law’s “claim to correctness.” The inquiry takes us deep into the nature of simple communication, back out to what it means to have a theory about the nature of law, and also in the direction of wondering about the interaction of legal theory and practical reasoning—reasoning about how we should best act. The article offers reasons to question whether law in fact makes claims, at least in any straightforward sense. Even if one brackets that matter, there are reasons to raise doubts about what is in fact implicit in the act of lawmaking. At one level, an act of lawmaking does implicitly assert the authority to act in that way. Whether it also implies that the content of the action is morally good, or at least not clearly morally bad, is, at a minimum, a harder question.
