a This is an outline of a coherence theory of law. Its basic ideas are: reasonable support and weighing of reasons. All the rest is commentary.a (TM) These words at the beginning of the preface of this book perfectly indicate what On Law and Reason is about. It is a theory about the nature of the law which emphasises the role of reason in the law and which refuses to limit the role of reason to the application of deductive logic. (...) In 1989, when the first edition of On Law and Reason appeared, this book was ground breaking for several reasons. It provided a rationalistic theory of the law in the language of analytic philosophy and based on a thorough understanding of the results, including technical ones, of analytic philosophy. That was not an obvious combination at the time of the booka (TM)s first appearance and still is not. The result is an analytical rigor that is usually associated with positivist theories of the law, combined with a philosophical position that is not natural law in a strict sense, but which shares with it the emphasis on the role of reason in determining what the law is. If only for this rare combination, On Law and Reason still deserves careful study. On Law and Reason also foreshadowed and influenced a development in the field of Legal Logic that would take place in the nineties of the 20th century, namely the development of non-monotonic (a defeasiblea (TM)) logics for the analysis of legal reasoning. In the new Introduction to this second edition, this aspect is explored in some more detail. (shrink)

Con la intención de aclarar el significado de la legalidad y de sus principios, el artículo desarrolla aquellos aspectos de la concepción del derecho de Lon Fuller que demuestran que legalidad y exterminio son incompatibles. Después, cuestiona los planteamientos defendidos por los iuspositivistas en el debate sobre el derecho nazi, porque se basan en una incorrecta identificación entre derecho y orden social, lo que lleva a los iuspositivistas a valorar el derecho exclusivamente en función de su utilidad para el gobernante (...) y no en función de lo que supone para los gobernados.

This paper discusses the place of philosophical naturalism in the philosophy of law, with special reference to Scandinavian Realism. Hägerström originated a non-cognitivist analysis of certain fundamental legal concepts, but he also proposed an error theory. The two approaches are incompatible, but were not always clearly distinguished. Among his followers, Olivecrona and Ross gradually abandoned the latter, at least from the late 1940s. Many accounts of their views are unclear, because the presence of these two kinds of analysis, their incompatibility, (...) and the gradual abandonment of one, has often been overlooked. A corollary of the discussion is that there are some important corrigenda in the entry “Naturalism in legal philosophy” in the Stanford Encyclopedia of Philosophy. (shrink)

The author discusses a number of issues in the theory of legal sources. The first topic is whether sources should be conceived of as acts or texts. The alternatives are connected with two competing theories of legal interpretation (viz., the cognitive theory and the sceptical theory), which entail different concepts of legal rules and law‐making. The second topic is whether a “formal” or a “material” criterion of recognition of sources should be preferred. The third section is devoted to the analysis (...) of rules of change. Four theories of rules of change are discussed, and five kinds of such rules are distinguished. The fourth section concerns judicial law‐making, with special reference to the creation of new legal rules by constitutional courts. (shrink)
