Eugenio Bulygin is a distinguished representative of legal science and legal philosophy as they are known on the European continent - no accident, given the role of the civil law tradition in his home country, Argentina. Over the past half-century, Bulygin has engaged virtually all major legal philosophers in the English-speaking countries, including H.L.A. Hart, Ronald Dworkin, and Joseph Raz. Bulygin''s essays, several written together with his eminent colleagueand close friend Carlos E. Alchourrón, reflect the genre familiar from Alf Ross''s On Law and Justice, Hans Kelsen''s Pure Theory of Law, and Georg Henrik von Wright''s Norm and Action. Bulygin''s wide-ranging interests include most of the topics found under the rubric of analytical jurisprudence -interpretation and judicial reasoning, validity and efficacy of law, legal positivism and the problem of normativity, completeness and consistency of the legal system, the nature of legal norms, and the role of deontic logic in the law. The reader will take delight in the often agreeably unorthodox character of Bulygin''s views and in his hard-hitting arguments in defence of them. He challenges the received opinion on gaps in the law, on legal efficacy, on permissory norms, and on the criteriafor legal validity. Bulygin''s essays have been wellnigh inaccessible in the past, appearing in specialized journals, often in Spanish or German. They are now available for the first time in an English-language collection.

A considerable number of books and papers have analyzed normative concepts using new techniques developed by logicians; however, few have bridged the gap between the English legal culture and the Continental (i.e. European and Latin American) tradition in legal philosophy. This book addresses this issue by offering an introductory study on the many possibilities that logical analysis offers the study of legal systems. The volume is divided into two sections: the first covers the basic aspects of classical and deontic logic and its connections, advancing an explanation of the most important topics of the discipline by comparing different systems of deontic logic and exploring some of the most important paradoxes in its domain. The second section deals with the role of logic in the analysis of legal systems by discussing in what sense deontic logic and the logic of norm-propositions are useful tools for a proper understanding of the systematic structure of law.

Los trabajos de Eugenio Bulygin (1931-2021) han ejercido una influencia extraordinaria en la filosofía del derecho contemporánea. Durante más de cincuenta años, sus contribuciones han enriquecido los aspectos más importantes de la teoría analítica del derecho: el razonamiento jurídico, la reconstrucción de los conceptos jurídicos y la explicación de la naturaleza sistemática del derecho.Para conmemorar esa impresionante trayectoria de un filósofo excepcional y un maestro entrañable, se publican, en dos volúmenes, 47 trabajos originales de teóricos y filósofos del derecho de Argentina, Chile, Brasil, México, Colombia, Estados Unidos, España, Italia, Portugal, Alemania, Francia y Rusia. Todos estos artículos giran en torno a problemas y desafíos que Bulygin ha enfrentado a lo largo de casi seis décadas: la forma y naturaleza de los argumentos jurídicos, la posibilidad de una lógica de normas, la distinción entre normas y proposiciones normativas, los límites del derecho, la ontología de las normas y la plausibilidad del positivismo jurídico.

Este libro reúne las voces más lúcidas de la filosofía analítica del derecho contemporáneo –desde Alemania hasta Latinoamérica– en un diálogo transatlántico sin concesiones. En un escenario jurídico cada vez más dominado por consignas superficiales y discursos prefabricados, que oscila entre el moralismo ambiguo y el decisionismo arbitrario, esta obra despliega las herramientas lógicas para someter el fenómeno jurídico a análisis conceptual implacable.El trabajo que se propone acá es riguroso: desde los fundamentos lingüísticos y normativos del derecho (con Hart, Dworkin y Wittgenstein como faros críticos) hasta los dilemas éticos de Núremberg que desafiaron los límites entre derecho y moral. Los capítulos, van más allá del análisis teórico: son como conversaciones profundas con los grandes pensadores del derecho –el iusmoralismo, el positivismo, la lógica de los sistemas jurídicos, etc.– que interrogan la propia legitimidad del derecho en tiempos de crisis institucional.Lo que emerge es un manifiesto metodológico: solo el rigor analítico, aplicado sin dogmatismos, puede devolver al derecho su precisión conceptual perdida. Esta obra no es solo un tratado; es un llamado a rearmar la técnica jurídica con las herramientas de la filosofía más exigente. Un libro para juristas que no temen pensar.José L. Cusi-Alanoca
