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.

In support of my longstanding claim that the traditional divide between natural law and legal positivist theories of law, the present paper explores a variety of necessary connections between law and morality which are consistent with theories of law traditionally identified as positivist.

What is the relation between legal certainty and correctness? This question poses one of the perpetual problems of the theory and practice of law—and for this reason: The answer turns on the main question in legal philosophy, the question of the concept and the nature of law. Thus, in an initial step, I will briefly look at the concept and the nature of law. In a second step, I will attempt to explain what the concept and the nature of law, (...) thus understood, imply for the relation between legal certainty and correctness. Here three issues will be considered: first, the Radbruch formula as an answer to the problem of extreme injustice; second, the special case thesis, which claims that legal argumentation is a special case of general practical argumentation; and, third, the problem of the judicial development of the law.

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. (shrink)

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)

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. (shrink)

This new translation of the first Critique forms part of a fifteen-volume English-language edition of the works of Immanuel Kant under the general editorship of this volume’s editor-translators, Paul Guyer and Allen Wood. The edition, which is almost complete by now, comprises all of Kant’s published works along with extensive selections from his literary remains, his correspondence, and student transcripts of his lecture courses in metaphysics, ethics, logic, and anthropology. The Cambridge edition aims at a consistent English rendition of Kant’s (...) works, both within a given volume and across volumes. In terms of scope and detail, the Cambridge edition is unrivaled in any language, except for the authoritative Academy edition begun under the directorship of Wilhelm Dilthey in 1900, which, however, is still not completed and several volumes of which are in serious need of re-editing. In one case, that of the Opus postumum, the best edition currently available seems to be the one in the Cambridge edition. (shrink)
