Henry Richardson argues that we can determine our ends rationally. He constructs a rich and original theory of how we can reason about our final goals. Richardson defuses the counter-arguments for the limits of rational deliberation, and develops interesting ideas about how his model might be extended to interpersonal deliberation of ends, taking him to the borders of political theory. Along the way Richardson offers illuminating discussions of, inter alia, Aristotle, Aquinas, Sidgwick, and Dewey, as well as the work of (...) several contemporary philosophers. (shrink)

Taking up a single question--"What does it mean to say a proposition of law is true?"--this book advances a major new account of truth in law. Drawing upon the later philosophy of Wittgenstein, as well as more recent postmodern theory of the relationship between language, meaning, and the world, Patterson examines leading contemporary jurisprudential approaches to this question and finds them flawed in similar and previously unnoticed ways. He offers a powerful alternative account of legal justification, one in which linguistic (...) practice--the use of forms of legal argument--holds the key to legal meaning. (shrink)

This book analyzes the uses of emotive language and redefinitions from pragmatic, dialectical, epistemic and rhetorical perspectives, investigating the relationship between emotions, persuasion and meaning, and focusing on the implicit dimension of the use of a word and its dialectical effects. It offers a method for evaluating the persuasive and manipulative uses of emotive language in ordinary and political discourse. Through the analysis of political speeches and legal arguments, the book offers a systematic study of emotive language in argumentation, rhetoric, (...) communication, political science and public speaking.

This book provides a systematic analysis of many common argumentation schemes and a compendium of 96 schemes. The study of these schemes, or forms of argument that capture stereotypical patterns of human reasoning, is at the core of argumentation research. Surveying all aspects of argumentation schemes from the ground up, the book takes the reader from the elementary exposition in the first chapter to the latest state of the art in the research efforts to formalize and classify the schemes, outlined (...) in the last chapter. It provides a systematic and comprehensive account, with notation suitable for computational applications that increasingly make use of argumentation schemes. (shrink)

Robert Alexy develops his influential theory of legal reasoning exploring the nature of legal argumentation and its relation to practical reasoning. In doing so he sheds light on fundamental questions of law and rationality, which are as crucial to practising lawyers and law students as they are to scholars of legal theory.

Are propositions of law true or false? If so, what does it mean to say that propositions of law are true and false? This book takes up these questions in the context of the wider philosophical debate over realism and anti-realism. Despite surface differences, Patterson argues that the leading contemporary jurisprudential theories all embrace a flawed conception of the nature of truth in law. Instead of locating that in virtue of which propositions of law are true, Patterson argues that lawyers (...) use forms of argument to show the truth of propositions of law. Additionally, Patterson argues that the realism/anti-realism debate in jurisprudence is part of a larger argument over the role of postmodernism in jurisprudence. For this, Patterson offers an analytic account of postmodernism and charts its implications for legal theory. This book will be of interest to those in legal theory, philosophy, social and political theory, and ethics. (shrink)

In this volume, Geurts takes discourse representation theory (DRT), and turns it into a unified account of anaphora and presupposition, which he applies not only to the standard problem cases but also to the interpretation of modal expressions, attitude reports, and proper names. The resulting theory, for all its simplicity, is without doubt the most comprehensive of its kind to date. The central idea underlying Geurts' 'binding theory' of presupposition is that anaphora is just a special case of presupposition projection. (...) But this is only one of the ways in which the concept of presupposition is taken beyond its traditional limits. Geurts shows, furthermore, that presupposition projection is crucially involved in several phenomena that are not usually viewed in presuppositional terms, such as modal subordination, de re readings of attitude reports, and rigid designation. While making his case for DRT and the binding theory, Geurts also presents an incisive analysis of what is probably still the most influential account of presupposition, viz. the satisfaction theory, demonstrating that there are fundamental problems not only with this theory but with the very framework in which it is couched.

In this study John Bowlin argues that Aquinas's moral theology receives much of its character and content from an assumption about our common lot: the good we desire is difficult to know and to will, in particular because of contingencies of various kinds - within ourselves, in the ends and objects we pursue, and in the circumstances of choice. Since contingencies are fortune's effects, Aquinas insists that it is fortune that makes good choice difficult. Bowlin then explicates Aquinas's treatment of (...) a number of topics in light of this difficulty: the moral and theological virtues, the first precepts of the natural law, the voluntariness of virtuous action, and the happiness available to us in this life. By noting that Aquinas proceeds with an eye on fortune's threats to virtue, agency, and happiness, Bowlin places him more precisely in the history of ethics, among Aristotle, Augustine, and the Stoics.

Develops a logical analysis of dialogue in which two or more parties attempt to advance their own interests. It includes a classification of the major types of dialogues and a discussion of several important informal fallacies.

The Pleadings Game is a major contribution to artificial intelligence and legal theory. The book draws on jurisprudence and moral philosophy to develop a formal model of argumentation called the pleadings game. From a technical perspective, the work can be viewed as an extension of recent argumentation-based approaches to non-monotonic logic: (1) the game is dialogical rather than mono-logical; (2) the validity and priority of defeasible rules is subject to debate; and (3) resource limitations are acknowledged by rules for fairly (...) dividing the burdens of representation and proof among the players. Gordon's work evaluates important jurisprudential theories of argumentation and reasoning in the context of the U.S. commercial law on secured transactions. Audience: It is not necessary to have a formal background in law to appreciate The Pleadings Game. It will be of equal interest to both the artificial intelligence community and legal theorists.

What are our duties or rights? How should we act? What are we responsible for? Joseph Raz examines the philosophical issues underlying these everyday questions. He explores the nature of normativity--the reasoning behind certain beliefs and emotions about how we should behave--and offers a novel account of responsibility.

Deliberative democracy puts communication and talk at the centre of democracy. Foundations and Frontiers of Deliberative Governance takes a fresh look at the foundations of the field, and develops new applications in areas ranging from citizen participation to the democratization of authoritarian states to the global system.

Temkin's book is a very original and deeply unsettling work of skeptical philosophy that mounts an important new challenge to contemporary ethics.

By far the most detailed surviving examination by any ancient Greek sceptic of epistemology and logic, this work critically reviews the pretensions of non-sceptical philosophers, to have discovered methods for determining the truth, either through direct observation or by inference from the observed to the unobserved. A fine example of the Pyrrhonist sceptical method at work, it also provides extensive information about the ideas of other Greek thinkers, which in many instances, are poorly preserved in other sources.

Presenting the most comprehensive and lucid account of the topic currently available, Robert Audi's "Practical Reasoning and Ethical Decision" is essential reading for anyone interested in the role of reason in ethics or the nature of human action. The first part of the book is a detailed critical overview of the influential theories of practical reasoning found in Aristotle, Hume and Kant, whilst the second part examines practical reasoning in the light of important topics in moral psychology - weakness of (...) will, self-deception, rationalization and others. In the third part, Audi describes the role of moral principles in practical reasoning and clarifies the way practical reasoning underlies ethical decisions. He formulates a comprehensive set of concrete ethical principles, explains how they apply to reasoning about what to do, and shows how practical reasoning guides moral conduct. (shrink)

The thesis that propositions of law are intrinsically arguable is opposed by the antithesis that the Rule of Law is valued for the sake of legal certainty. The synthesis considers the insights of theories of rhetoric and proceduralist theories of practical reason, then locates the problem of indeterminacy of law in the context of the challengeable character of governmental action under free governments. This is not incompatible with, but required by the Rule of Law, which is misstated as securing legal (...) certainty. Defeasible certainty is the most that is desirable or achievable. (shrink)

IT is strange that the informal fallacies should strike us as such obvious breaches of thinking and advocacy, yet should have met with such little success in finding a respectable home within mature logical theory. It might seem that respectable and mature logical theory is most mature and most respectable in the theory of propositions, and that its maturity and respectability in the other logical domains rapidly diminish in inverse proportion to the susceptibility of those domains to be reduced to (...) the logic of propositions. But we are not anxious to promote so severe a view of theoretical accomplishment, and we shall suppose that, at the very least, the informal fallacies have a degree of systematicity that will at once advance our understanding of them nicely beyond the level of intuitive impressions, and also place into retirement the hopelessly inadequate accounts that litter too many otherwise admirable textbooks.

what is now the mainstream view as to the best way forward in the dream of engineering reliable software systems out of autonomous agents. The way of using formal logics to specify, implement and verify distributed systems of interacting units using a guiding analogy of beliefs, desires and intentions. The implicit message behind the book is this: Distributed Artificial Intelligence (DAI) can be a respectable engineering science. It says: we use sound formal systems; can cite established philosophical foundations; and will (...) be able to build reliable and flexible software systems. (shrink)

The author argues that philosophers' attempts to use philosophy of language to solve problems of jurisprudence have often failed- the most dramatic failure being that of Jeremy Bentham. H.L.A.Hart made some related mistakes in his creative use of philosophy of language, yet his focus on language still yields some very significant insights for jurisprudence: the context principle (that the correct application of linguistic expressions typically depends on context in ways that are important for jurisprudence), the diversity principle (that grounds of (...) correct application of legal language may be diverse), and the importance of vagueness.

This paper presents a formalization of informal logic using the Carneades Argumentation System, a formal, computational model of argument that consists of a formal model of argument graphs and audiences. Conflicts between pro and con arguments are resolved using proof standards, such as preponderance of the evidence. Carneades also formalizes argumentation schemes. Schemes can be used to check whether a given argument instantiates the types of argument deemed normatively appropriate for the type of dialogue.

Using tools like argument diagrams and profiles of dialogue, this paper studies a number of examples of everyday conversational argumentation where determination of relevance and irrelevance can be assisted by means of adopting a new dialectical approach. According to the new dialectical theory, dialogue types are normative frameworks with specific goals and rules that can be applied to conversational argumentation. In this paper is shown how such dialectical models of reasonable argumentation can be applied to a determination of whether an (...) argument in a specific case is relevant are not in these examples. The approach is based on a linguistic account of dialogue and text from congruity theory, and on the notion of a dialectical shift. Such a shift occurs where an argument starts out as fitting into one type of dialogue, but then it only continues to makes sense as a coherent argument if it is taken to be a part of a different type of dialogue.

Argumentation is a dialogical attempt to bring about a desired change in the beliefs of another agent – that is, to trigger a specific belief revision process in the mind of such agent. However, so far formal models of belief revision widely neglected any systematic comparison with argumentation theories, to the point that even the simplest argumentation structures cannot be captured within such models. In this essay, we endeavour to bring together argumentation and belief revision in the same formal framework, (...) and to highlight the important role played by Toulmin’s layout of argument in fostering such integration.

In Rhetoric 1360b05-1365b21, Aristotle naturally assumes the debatable, exceptionable and multidimensional character of the kind of allegations, adduced as reasons for the proposals which act as conclusions of the practical arguments typical of political debate. This is a problem which has been currently addressed in terms of the prima facie incommensurability caused by the multi-dimensionality of value-based argumentation, an approach that seems to lead us to an evaluative and dialectical dead-end. But in the Aristotelian text, we find a different tactic. (...) Aristotle analyses in very explicit and revealing terms how the “continuum between argument and argument criticism” and the meta-argumentative scaling takes place in deliberative discourse. Starting with a rather simple practical means-ends scheme, just effective in very exceptional situations, the text of the Rhetoric advances progressively towards the examination of additional arguments defending the suitability of different ends, in case there is no agreement about them, and then towards the even more clearly meta-argumentative means of weighing and ordering different suitable ends. Aristotle shows us, thus, how we manage when facing prima facie incommensurability: we keep arguing and meta-arguing. (shrink)

The current literature on presupposition focuses almost exclusively on the projection problem: the question of how and why the presuppositions of atomic clauses are projected to complex sentences which embed them. Very little attention has been paid to the question of how and why these presuppositions arise at all. As Kay (1992, p.335) observes, “treatments of the presupposition inheritance problem almost never deal with the reasons that individual words and constructions give rise, in the first place, to the particular presuppositions (...) that they do.”1 This is the question on which this paper will focus.
