Ludwig Wittgenstein is perhaps the greatest philosopher of the twentieth century, and certainly one of the most original in the entire Western tradition. Given the inaccessibility of his work, it is remarkable that he has inspired poems, paintings, films, musical compositions, titles of books -- and even novels. In his splendid biography, Ray Monk has made this very compelling human being come alive in a way that perfectly explains the fascination he has evoked. Wittgenstein's life was one of great moral (...) and spiritual depth. Although his work addresses problems of logic, language, mind, and knowledge, he often described it as having an ethical point, and once said that he "could not help seeing every problem from a religious point of view." In successfully bridging the gap assumed by many to exist between Wittgenstein's life and his work, Monk's biography helps to explain the interest in Wittgenstein's later philosophy on the part of Buddhist scholars.

Change in View offers an entirely original approach to the philosophical study of reasoning by identifying principles of reasoning with principles for revising one's beliefs and intentions and not with principles of logic. This crucial observation leads to a number of important and interesting consequences that impinge on psychology and artificial intelligence as well as on various branches of philosophy, from epistemology to ethics and action theory. Gilbert Harman is Professor of Philosophy at Princeton University. A Bradford Book.

The fundamental question of the ethics of belief is "What ought one to believe?" According to the traditional view of evidentialism, the strength of one's beliefs should be proportionate to the evidence. Conventional ways of defending and challenging evidentialism rely on the idea that what one ought to believe is a matter of what it is rational, prudent, ethical, or personally fulfilling to believe. Common to all these approaches is that they look outside of belief itself to determine what one (...) ought to believe. In this book Jonathan Adler offers a strengthened version of evidentialism, arguing that the ethics of belief should be rooted in the concept of belief—that evidentialism is belief's own ethics. A key observation is that it is not merely that one ought not, but that one cannot, believe, for example, that the number of stars is even. The "cannot" represents a conceptual barrier, not just an inability. Therefore belief in defiance of one's evidence (or evidentialism) is impossible. Adler addresses such questions as irrational beliefs, reasonableness, control over beliefs, and whether justifying beliefs requires a foundation. Although he treats the ethics of belief as a central topic in epistemology, his ideas also bear on rationality, argument and pragmatics, philosophy of religion, ethics, and social cognitive psychology.

Looking back on it, it seems almost incredible that so many equally educated, equally sincere compatriots and contemporaries, all drawing from the same limited stock of evidence, should have reached so many totally different conclusions---and always with complete certainty.

This is a welcome reprint of a book that continues to grow in importance.

This is an introductory guidebook to the basic principles of how to construct good arguments and how to criticeze bad ones. It is non-technical in its approach and is based on 150 key examples, each discussed and evaluated in clear, illustrative detail. Professor Walton, a leading authority in the field of informal logic, explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound strategies for reasoned persuasion and critical (...) responses. Among the many subjects covered are: forms of valid argument, relevance, appeals to emotion, personal attack, uses and abuses of expert opinion, problems in deploying statistics, loading terms, equivocation, arguments from analogy, and techniques of posing, replying to, and criticizing questions. The book will be ideally suited to courses in informal logic and in the introduction to philosophy. It will also prove valuable to studetns of pragmatics, rhetoric, and speech communication.

The thesis that scientific inquiry must operate within moral constraints is familiar and unobjectionable in cases involving immoral treatment of experimental subjects, as in the infamous Tuskegee experiments. However, in Science, Truth, and Democracy1 and related work,2 Philip Kitcher envisions a more controversial set of constraints. Specifically, he argues that inquiry ought not to be pursued in cases where the consequences of its pursuit are likely to affect negatively the lives of individuals who comprise a socially underprivileged group. This constraint (...) is controversial because it imposes moral obligations upon scientific inquirers that they do not have as moral agents generally.3 That is, whereas the familiar prohibitions against the violation of the rights of experimental subjects amount to the enforcement of fundamental moral obligations in the laboratory and the denial that such obligations can be overridden for the sake of scientific discovery, Kitcher argues that scientists incur in virtue of their role as scientists a set of distinctive moral obligations with regard to individuals belonging to underprivileged groups. In this way, Kitcher is proposing an autonomous ethics of inquiry rather than arguing for the extension of familiar moral obligations to scientific inquiry. (shrink)

This paper reviews the history of AI & Law research from the perspective of argument schemes. It starts with the observation that logic, although very well applicable to legal reasoning when there is uncertainty, vagueness and disagreement, is too abstract to give a fully satisfactory classification of legal argument types. It therefore needs to be supplemented with an argument-scheme approach, which classifies arguments not according to their logical form but according to their content, in particular, according to the roles that (...) the various elements of an argument can play. This approach is then applied to legal reasoning, to identify some of the main legal argument schemes. It is also argued that much AI & Law research in fact employs the argument-scheme approach, although it usually is not presented as such. Finally, it is argued that the argument-scheme approach and the way it has been employed in AI & Law respects some of the main lessons to be learnt from Toulmin’s The Uses of Argument. (shrink)

This article reacts against the undesirable ideological separation between dialectical and rhetorical approaches to argumentative discourse. It argues that a sound evaluation of argumentation requires an analysis that reveals all aspects of the discourse pertinent to critical testing. To explain the rationale of the various moves made in the discourse and the strategic patterns behind them, not only the interlocutors' dialectical goals must be taken into account, but also their rhetorical goals. After explaining how rhetorical insight can be instrumental in (...) deepening and justifying a dialectical analysis, an integrated analysis is made of the rhetorical strategies that are brought to bear in an advertorial published by the oil company Shell.

According to Thomas Nagel we have a natural impulse to transcend our personal point of view. However, it appears to be difficult to give this notion of transcendence any real content while maintaining a connection with everyday speech and behaviour. In this essay I show that the description of what happens in a discussion when a speaker convinces a listener suggests an interesting interpretation of transcendence. The notion of 'truth' linked to the listener who is being convinced introduces a normative (...) dimension in argumentation. This inescapable normative stance of the listener saddles her with the obligation to answer all credible objections against all arguments she has accepted. The evaluation of the arguments is not reserved for the participants of a discussion. Nothing more is required. For instance, the notion of a universal consensus has no place in the analysis of argumentation. If there is a universal dimension in argumentation and discussion, it is because there is no way of telling where convincing objections may come from. (shrink)

We argue that there are three norms of critical discussion in stark relief in Republic I. The first we see in the exchange with Cephalus---that we interpret each other and contribute to discussions in a maximally argumentative fashion. The second we seein the exchange with Polemarchus---that in order to cooperate in dialectic, interlocutors must maintain a distance between themselves and the theses they espouse. This way they can subject the views to serious scrutiny without the risk of personal loss. Third, (...) and finally, from Socrates’ exchange with Thrasymachus, it is clear that uncooperative discussants must be handled in a fashion that reinforces the goals of dialectic. So Thrasymachus is refuted and silenced not just for the sake of correcting his definition of justice, but also for the sake of those listening. (shrink)

Evidentialism is the view that subjects should believe neither more than nor contrary to what their current evidence supports. I will critically present two arguments for the view. A common source of resistance to evidentialism is that there are intuitive cases where subjects should believe contrary to their evidence. I will present modest evidentialism as the view that subjects should believe in accord with what their evidence supports, but that this norm may be overridden under certain conditions. As such, a (...) modest evidentialismaccommodates the intuitions behind a good deal of traditional anti-evidentialism. (shrink)

This book concentrates on argumentation as it emerges in ordinary discourse, whether the discourse is institutionalized or strictly informal. Crucial concepts from the theory of argumentation are systematically discussed and explained with the help of examples from real-life discourse and texts. The basic principles are explained that are instrumental in the analysis and evaluation of argumentative discourse. Methodical instruments are offered for identifying differences of opinion, analyzing and evaluating argumentation and presenting arguments in oral and written discourse. In addition, the (...) book provides a great variety of exercises and assignments to improve the students' skill in presenting argumentation. The authors begin their treatment of argumentation theory at the same juncture where argumentation also starts in practice: The difference of opinion that occasions the evolvement of the argumentation. Each chapter begins with a short summary of the essentials and ends with a number of exercises that students can use to master the material. _Argumentation_ is the first introductory textbook of this kind. It is intended as a general introduction for students who are interested in a proper conduct of argumentative discourse. Suggestions for further reading are made for each topic and several extra assignments are added to the exercises. Special features: * A concise and complete treatment of both the theoretical backgrounds and the practice of argumentation analysis and evaluation. * Crucial concepts from pragmatics presented in a non-technical way; introducing the theory of verbal communication. * Unique coverage of both oral and written presentation of arguments. * Exercises and assignments based on real-life texts from a variety of contexts.
