In this masterful work, both an illumination of Kant's thought and an important contribution to contemporary legal and political theory, Arthur Ripstein gives a comprehensive yet accessible account of Kant's political philosophy. In addition to providing a clear and coherent statement of the most misunderstood of Kant's ideas, Ripstein also shows that Kant's views remain conceptually powerful and morally appealing today.

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. (shrink)

The most obvious way of settling disagreements peacefully is to take a vote. Yet, as Jeremy Waldron points out, the attitudes of philosophers and political theorists towards majority voting have ranged from indifference to hostility. Piled on top of all this scorn for legislation comes further scorn from social choice theorists, who insist that majority rule is useless as a means of making decisions.

In, Kant defends a position that cannot be salvaged. The essay is nonetheless important because it helps us understand his philosophy of law and, more specifically, his interpretation of the social contract. Kant considers truthfulness a strict legal duty because it is the necessary condition for the juridical state. As attested by Kants arguments against the death penalty, not even the right to life has such strict unconditional status. Within the juridical state, established by the social contract, the innate right (...) to freedom is transformed into a bundle of merely positive rights, including the right to life. Understanding the reason for the rejection of thus helps us understand the, in a sense, character of Kant’s legal philosophy. In conclusion, some suggestions are made to bring his position closer to our common moral understanding. (shrink)

This paper argues that the political adage “Be ye prudent as serpents and guileless as doves” involves three different types of relation between prudence and morality, namely: unification (Vereinigung), subordination (Unterordnung), and association (Beigesellung). I maintain that these relations are set up according to the same principle that determines the relationship between mechanical and teleological causality in the third Critique. Thus, I argue that morality and prudence are much more systematically related within the system of critical philosophy than is normally (...) assumed in the literature and that this is made possible by way of an intimate relationship between prudence and teleological judgment.

This article argues that legal positivism is best understood as a political tradition which rejects the Separation Thesis—the thesis that there is no necessary connection between law and morality. That tradition was committed for some time to eliminating the conceptual space in which the common law tradition and its style of reasoning operate. A genealogical reconstruction of the tradition shows that when positivist judges are forced to operate in that space, they have to adapt their own style of reasoning to (...) some of the constraints of that space. That most contemporary positivists will attempt to disown such judges is symptomatic of deep problems in contemporary positivism, problems which stem from the attempt to detach positivism from its political tradition. So a recent neo-Benthamite revival in legal theory is welcome. Not only does it reunite positivism with its political tradition, but it also opens the way for a productive debate between positivism and its critics. ‘As for the philosophical approach, once so lively and dominant, it seems at times today rather tired, and exhibits its unease by seeking revitalization in flirtations with the absurd. But the problems of legal theory remain as fascinating as they ever were, and, if there is any grand message in these essays, it is that the historical study of legal institutions may have more to offer to their solution than has yet been appreciated’.1.

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. (shrink)
