The infamous difficulty of Lacan's writing has its own, very apt synecdoche: the matheme. What makes this ‘little letter’ that structures the signifier so apposite a device is how it stymies even those sophisticated readers for whom Lacan is as close-readable as Mallarm e. The proposition offered here is that this crisis of reading is not the consequence of either some terrible mistake or egregious failing in character, but rather a typically Lacanian move by which his text stages the very (...) theory it is presumably explicating. This article suggests that by striving to read the matheme, instead of seizing upon excuses to avoid it, we can begin to understand what Lacan meant when he said that everything emerges from the structure of the signifier.

Aristotle's way of thinking has normally been understood as hostile to any liberal, pluralistic, or commercial society. In Liberal Nature, Rasmussen and Den Uyl set out to show that the Aristotelian approach to ethics supports the natural rights which form the most secure basis for liberal principles. The authors lay the foundations for their thesis by rebutting the most prominent arguments against the Aristotelian approach; they then offer a new interpretation for Aristotelian ethics as a natural-end ethics in which human (...) flourishing is the ultimate moral standard.

Vol. presents a method for critically evaluating relevance in arguments based on case studies & a new relevance theory incorporating techniques of argumentation theory, logic & artificiaI intelligence. For scholars/students in argumentation & rhetoric.

Argumentation, which can be abstractly defined as the interaction of different arguments for and against some conclusion, is an important skill to learn for everyday life, law, science, politics and business. The best way to learn it is to try it out on real instances of arguments found in everyday conversational exchanges and legal argumentation. The introductory chapter of this book gives a clear general idea of what the methods of argumentation are and how they work as tools that can (...) be used to analyze arguments. Each subsequent chapter then applies these methods to a leading problem of argumentation. Today the field of computing has embraced argumentation as a paradigm for research in artificial intelligence and multi-agent systems. Another purpose of this book is to present and refine tools and techniques from computing as components of the methods that can be handily used by scholars in other fields. (shrink)

Walton's book is a study of several fallacies in informal logic. Focusing on question-answer dialogues, and committed to a pragmatic rather than a semantic approach, he attempts to generate criteria for evaluating good and bad questions and answers. The book contains a discussion of such well-recognized fallacies as many questions, black-or-white questions, loaded questions, circular arguments, question-begging assertions and epithets, ad hominem and tu quoque arguments, ignoratio elenchi, and replying to a question with a question. In addition, Walton develops several (...) artificial dialogue games and has an excellent discussion of burden of proof in nonlegal contexts. The discussion is for the most part nontechnical and does not presuppose any training in formal logic. It is illustrated with many (sometimes overlong) examples of fallacies drawn from real life--mostly debates in the Canadian House of Commons. . . . Walton's book breaks new ground on a number of issues. Choice This first full-length study of logical fallacies, errors, faults, illicit attacks, blunders, and other critical deficiencies in interrogation and reply has been written in the tradition of informal fallacies in logic. It is especially valuable, readable, and interesting because of the 139 case studies it presents, many of these case studies come from political debates and some from interviews, legal cross-examinations, and other sources. Walton uses these challenging examples of tricky, aggressive, argumentative, or fallacious questions to develop coherent and pragmatic guidelines for criticizing questionable questions (and in some cases their replies) on logical grounds. Among the types of problematic questions analyzed are: the traditional so-called fallacy of many questions, illustrated by the famous Have you stopped beating your wife?; black and white questions; terminologically loaded questions; and questions containing personal attacks. These and other types of problematic questions as well as evasive replies and replying to a question with a question are studied. Critical errors of reasoning are identified and analyzed by developing context-based, normative models of reasonable dialogue in which a questioner must have freedom to ask informative and probing questions, and the respondent must be constrained to give reasonably direct, not overly evasive answers. In this era of negative and evasive political campaigning, with candidates employing skillful tactics of manipulating public opinion to assure election rather than taking clear stands and seriously debating issues in an informed and sincere manner, Question-Reply Argumentation is especially relevant reading for those who take democracy seriously. The methods used reflect a significant shift from earlier semantically based theories to current pragmatic, dialogue-based models, and will be of interest to logicians and linguists. The volume's conclusions should challenge some current preconceptions. Recommended reading for courses in logic, speech communications, linguistics, philosophy of language, areas of political science relating to political discourse and debate, courses on questioning in cognitive psychology, and courses on critical thinking in education.

The aim of the paper is to present a typology of argument schemes. In first place, we found it helpful to define what an argument scheme is. Since many argument schemes found in contemporary theories stem from the ancient tradition, we took in consideration classical and medieval dialectical studies and their relation with argumentation theory. This overview on the main works on topics and schemes provides a summary of the main principles of classification. In the second section, Walton’s theory is (...) briefly explained to introduce the schemes classification and its different levels. At least, the final part shows the main application of the schemes in computing and AI. -/- . (shrink)

A useful contribution to theories of argumentation and public address criticism, this book uses a pragmatic approach to understanding conversation as a way of elucidating the use of appeals to pity and sympathy.

Behavioral paternalism raises deep concerns that do not arise in traditional welfare economics. These concerns stem from behavioral paternalism’s acceptance of the defining axioms of neoclassical rationality for normative purposes, despite having rejected them as positive descriptions of reality. We argue that behavioral paternalists have indeed accepted neoclassical rationality axioms as a welfare standard; that economists historically adopted these axioms not for their normative plausibility, but for their usefulness in formal and theoretical modeling; that broadly rational individuals might fail to (...) satisfy the axioms for various reasons, making them unpersuasive as normative criteria; and that even if their violation did constitute irrationality, that would not justify paternalists’ choosing among inconsistent preferences to define an individual’s “true” preferences.

In response to the growing recognition of informal logic as a discipline in its own right, this collection of essays from leading contributors in the field provides the formative knowledge and historical context required to understand the development of a so far little studied subject area.

Patient autonomy, as exercised in the informed consent process, is a central concern in bioethics. The typical bioethicist's analysis of autonomy centers on decisional capacity—finding the line between autonomy and its absence. This approach leaves unexplored the structure of reasoning behind patient treatment decisions. To counter that approach, we present a microeconomic theory of patient decision-making regarding the acceptable level of medical treatment from the patient's perspective. We show that a rational patient's desired treatment level typically departs from the level (...) yielding an absence of symptoms, the level we call ideal. This microeconomic theory demonstrates why patients have good reason not to pursue treatment to the point of absence of physical symptoms. We defend our view against possible objections that it is unrealistic and that it fails to adequately consider harm a patient may suffer by curtailing treatment. Our analysis is fruitful in various ways. It shows why decisions often considered unreasonable might be fully reasonable. It offers a theoretical account of how physician misinformation may adversely affect a patient's decision. It shows how billing costs influence patient decision-making. It indicates that health care professionals' beliefs about the ‘unreasonable’ attitudes of patients might often be wrong. It provides a better understanding of patient rationality that should help to ensure fuller information as well as increased respect for patient decision-making. (shrink)

In this paper, the traditional view that argumentum ad ignorantiam is a logical fallacy is challenged, and lessons are drawn on how to model inferences drawn from knowledge in combination with ones drawn from lack of knowledge. Five defeasible rules for evaluating knowledge-based arguments that apply to inferences drawn under conditions of lack of knowledge are formulated. They are the veridicality rule, the consistency of knowledge rule, the closure of knowledge rule, the rule of refutation and the rule for argument (...) from ignorance. The basic thesis of the paper is that knowledge-based arguments, including the argument from ignorance, need to be evaluated by criteria for epistemic closure and other evidential rules that are pragmatic in nature, that need to be formulated and applied differently at different stages of an investigation or discussion. The paper helps us to understand practical criteria that should be used to evaluate all arguments based on knowledge and/or ignorance. (shrink)

The period leading up to the Revolutions of 1848 was a seminal moment in the history of political thought, demarcating the ideological currents and defining the problems of freedom and social cohesion which are among the key issues of modern politics. This 2006 anthology offers research on Hegel's followers in the 1830s and 1840s. With essays by philosophers, political scientists, and historians from Europe and North America, it pays special attention to questions of state power, the economy, poverty, and labour, (...) as well as to ideas on freedom. The book examines the political and social thought of Eduard Gans, Ludwig Feuerbach, Max Stirner, Bruno and Edgar Bauer, the young Engels, and Marx. It places them in the context of Hegel's philosophy, the Enlightenment, Kant, the French Revolution, industrialization, and urban poverty. It also views Marx and Engels in relation to their contemporaries and interlocutors in the Hegelian school. (shrink)

Political philosophers often formulate the problem of distributive justice as the problem of how the government ought to distribute different types of goods—for example, income or health care—to its citizens. They therefore presuppose that the government is a unitary agent that governs its citizens directly. However, although a number of governments are unitary in this way, many are federations, exhibiting a division of sovereignty between two or more levels of government having independent grounds of authority. In contrast to unitary states, (...) therefore, within a federation, two or more levels of government directly govern their citizens and are directly accountable to them. Because of the way in which different levels of government in a federation can separately affect the distribution of goods in society, federations face resource allocation problems that are far more complex than those of unitary states. In addition to determining what a just distribution of goods is, federations must also determine (1) whether distributive justice is a shared responsibility amongst different levels of government, and, if so, (2) how this shared responsibility should be allocated between them.

Glenberg's account falls short in several respects. Besides requiring clearer explication of basic concepts, his account fails to recognize the autonomous nature of perception. His account of what is remembered, and its description, is too static. His strictures against connectionist modeling might be overcome by combining the notions of psychological space and principled learning in an embodied and situated network.

Shepard's notion of “internalisation” is better interpreted as a simile than a metaphor. A fractal encoding model of visual perception is sketched, in which image elements are transformed in such a way as to maximise symmetry with the current input. This view, in which the transforming system embodies what has been internalised, resolves some problems raised by the metaphoric interpretation. [Hecht; Shepard].

This chapter puts Sellars' project of unifying his two images in conversation with that of understanding how the two truth, the conventional and ultimate truth, are related in Buddhism, and in Madhyamaka in particular.

It is surely not difficult to see that our time is a time of birth and transition to a new period. The spirit has broken with what was hitherto the world of its existence and imagination and is about to submerge all this in the past; it is at work giving itself a new form. To be sure, the spirit is never at rest but always engaged in ever progressing motion.... the spirit that educates itself matures slowly and quietly toward (...) the new form, dissolving one particle of the edifice of its previous world after the other,.... This gradual crumbling... is interrupted by the break of day that, like lightning, all at once reveals the edifice of the new world. Hegel, The Phenomenology of Spirit, 1807.. (shrink)

Why is beauty consoling? Ancient and Medieval Western philosophy was primarily concerned with beauty in relation to truth and goodness. The theistic religions assume a link between beauty, goodness and truth, all of which are viewed as Divine attributes. This is one reason for the iconoclasm that all three Abrahamic religions share to a greater or lesser degree. Yet, creative fictions of great artistic beauty aspire to a certain truthfulness. A work of the imagination may deepen or purify our emotions (...) such that we gain a clearer understanding of reality. Beauty is consoling because it resolves the contradictions of experience; art can be a conduit to a supreme transcendent unity. The Iconic Imagination is both a reflection on the redemptive potential of art, and an investigation of the traditions of occidental Christianity, Judaism, Hinduism and Islam in their confrontations with the particular power of art to represent the transcendent. Throughout, Hedley argues that the malaise of much contemporary reflection upon beauty is a consequence of the marginalisation of beauty's religious dimension. (shrink)
