"Logic and law have a long history in common, but the influence has been mostly one-sided, except perhaps in the 5th and 6th centuries B.C., where disputes at the market place or in tribunals in Greece seem to have stimulated a lot of reflection among sophistic philosophers on such topics as language and truth. Most of the time it was logic that influenced legal thinking, but in the last 50 years logicians began to be interested in normative concepts and hence in law"--

Book Description
These 13 papers collected from several meetings of the Society for Exact Philosophy from 1993-96 take a variety of approaches to the task of integrating normative and defeasible reasoning. While most of the papers propose some version of defeasible deontic logic, a few consider alternatives approaches to solving some of the puzzles of normative reasoning that deontic reasoning has failed to resolve. The authors also describe standard deontic logic. Name index only. Annotation copyrighted by Book News, Inc., Portland, OR

Book Description
This book describes extensions of deontic logic. Deontic logic is a branch of philosophical logic involving reasoning with norms, obligations, prohibitions and permissions. The extensions concern the logical structure of legal rules and legal reasoning. Their function is to improve the representation of legal knowledge and enhance deontic logic through increased expressibility. The resulting formulas acquire new meanings, not expressible in standard deontic logic, which are subject to fresh interpretations. The author offers an extensive analysis of the representation of actors, to whom the norms are directed, and authorities who enact the norms. Moreover, a distinction is made between enactment and applicability. A modality of enactment can be used to express inconsistent enacted norms in a consistent way. An authority-hierarchy is introduced to filter out the applicable norms from the set of enacted norms. Some related philosophical questions will be discussed regarding the applications of formalisms that are intrinsic to practical science with respect to `consistency' and `universality'. The formalisms and applications considered here are relevant for law, philosophy and computer science, with a special focus on the improvement of legal expert systems and intelligent support for legal professionals.

Book Description
The Handbook of Deontic Logic and Normative Systems presents a detailed overview of the main lines of research on contemporary deontic logic and related topics. Although building on decades of previous work in the field, it is the first collection to take into account the significant changes in the landscape of deontic logic that have occurred in the past twenty years. These changes have resulted largely, though not entirely, from the interaction of deontic logic with a variety of other fields, including computer science, legal theory, organizational theory, economics, and linguistics. This first volume of the Handbook is divided into three parts, containing nine chapters in all, each written by leading experts in the field. The first part concentrates on historical foundations. The second examines topics of central interest in contemporary deontic logic. The third presents some new logical frameworks that have now become part of the mainstream literature. A second volume of the Handbook is currently in preparation, and there may be a third after that.

Book Description
This book intends to unite studies in different fields related to the development of the relations between logic, law and legal reasoning. Combining historical and philosophical studies on legal reasoning in Civil and Common Law, and on the often neglected Arabic and Talmudic traditions of jurisprudence, this project unites these areas with recent technical developments in computer science. This combination has resulted in renewed interest in deontic logic and logic of norms that stems from the interaction between artificial intelligence and law and their applications to these areas of logic. The book also aims to motivate and launch a more intense interaction between the historical and philosophical work of Arabic, Talmudic and European jurisprudence. The publication discusses new insights in the interaction between logic and law, and more precisely the study of different answers to the question: what role does logic play in legal reasoning? Varying perspectives include that of foundational studies (such as logical principles and frameworks) to applications, and historical perspectives.

Book Description
In consequence of an increased interest in problems relating to human action, normative concepts have been much discussed by philosophers and logicians in the past twenty years. Deontic logic, which deals with the normative use of language and such normative concepts as obligation, prohibition and permission, has become one of the most intensively cultivated areas of formal logic. Important investigations have been carried out which have shed considerable light on various aspects of the normative phenomenon and a great number of different systems of deontic logic have been developed. This progressive proliferation of deontic logics not only shows the great interest of logicians in normative discourse, but also reflects a basic perplexity: the lack of suitable criteria of adequacy for the interpretation of deontic calculi and hence difficulty in decid ing which of the systems provides the best reconstruction of the underlying normative concepts and can therefore be applied with the most fruitful results. This difficulty is so great that some authors have even expressed doubts about the practical usefulness of deontic logic. One of the sources of this perplexity lies in the absence of a well established pre-analytical basis for formal studies. It is sometimes even uncertain what the intuitive notions are that deontic logicians intend to reconstruct. In talking about obligations, prohibitions and permissions, they usually have in mind moral norms. But the choice of moral norm as an explicandum for the construction of a logic of norms has several disadvantages.

Book Description
The present study which I have subtitled A Study in Law and Logic was prompted by the question of whether an investigation into law and legal systems could lead to the discovery of unrevealed fundamental patterns common to all such systems. This question was further stimulated by two interrelated problems. Firstly, could an inquiry be rooted in specifically legal matters, as distinct from the more usual writings on deontic logic? Secondly, could such inquiry yield a theory which would nevertheless embrace a strict and simple logical structure, permitting substantive conclusions in legal matters to be deduced from simple rules governing some basic concepts? Before the development of deontic logic, W. N. Hohfeld devoted his efforts to this question at the beginning of this century. However, with this exception, few jurists have studied the interrelation between law and logic projected in this way. Nevertheless, two great names are to be found, Gottfried Wilhelm Leibniz and Jeremy Bentham-both philo sophers with legal as weIl as logical training. Bentham's investigations of logical patterns in law have only recently attracted attention; and as for Leibniz, his achievements are still almost totally unexplored (his most important writings on law and logic have not even been translated from Latin). My initial interest in the question was evoked by Professor Stig Kanger. Although primarily a logician and philosopher, Stig Kanger has been interested also in the fundamentals of legal theory.

Book Description
The study presented in this book was entered upon by me from a legal point of view. 'Legal logic' has been known for a long time, concerning itself with the methodology of legal and in particular judicial reasoning. In modern days, however, this 'legal logic' is sometimes also connected with modern formal logic, as it has been developed in the works of G. Boole, A. de Morgan, G. Frege, C.S. Peirce, E. Schroder, G. Peano, A.N. Whitehead, B. Russell and others. For me this gave rise to the as yet not very specific question about the meaning of modern symbolic logic for law. Already in an early stage it appeared that, although traditional legal logic and modern symbolic logic both concern logic, this may not create the misapprehension that a similar matter is at issue. Both concern themselves (among other things) with reasonings and reasoning. Traditional legal logic is, however, as it was said by the German legal theoretician K. Engisch: "a material logic that wants us to reflect on what we have to do if we -within the limits of actual possibility- wish to reach true, or at least correct judgements" (Engisch, 1964, p.5). Modern symbolic logic on the other hand is not concerned with the truth or correctness of the result of an argument, but with its validity, i.e. the question when or under which conditions the truth (correctness) of the conclusion is guaranteed by the truth (correctness) of the premisses.
