This introduction to logic, which aims to reflect recent advances in the field, focuses on natural language, analyzing the structure of arguments conducted in English. The text includes problems with which students can test their skills.

Reviews the scope, nature, and applications of the philosophical discipline, focusing on methods for distinguishing between valid and fallacious arguments and inferences.

This article outlines criteria for the evaluation of the argumentum ad hominem (argument against the person, or personal attack in argument) that is traditionally a part of the curriculum in informal logic. The argument is shown to be a kind of criticism which works by shifting the burden of proof in dialogue through citing a pragmatic inconsistency in an arguer's position. Several specific cases of ad hominem argumentation which pose interesting problems in analyzing this type of criticism are studied.

Hypocrites are generally regarded as morally-corrupt, cynical egoists who consciously and deliberately deceive others in order to further their own interests. The purpose of my essay is to present a different view. I argue that hypocrisy typically involves or leads to self-deception and, therefore, that real hypocrites are hard to find. One reason for this merging of hypocrisy into self-deception is that a consistent and conscious deception of society is self-defeating from the point of view of egoistical hypocrites. The best (...) way for them to achieve their ends would be to believe in the deception, thereby not only deceiving others but also themselves. If my thesis is sound, we ought to be more cautious in ascribing hypocrisy to people, and less harsh in our attitude toward hypocrites. (shrink)

This paper is ultimately about the nature of argumentation in general and about the nature of practical argumentation in particular. (Practical argumentation is the form of argumentation which aims at answering the question: ‘What is to be done?’) The approach adopted here is an indirect one. I analyze one traditional form of argumentive fallacyargumentum ad hominem and try to show that in some argumentative situations it is an intuitively legitimate move. These intuitions can be explained if we accept that practical (...) argumentation is also governed by the general rules of practical rationality. (shrink)

Appeal to expert judgement has become a wide-spread and unavoidable element in public debates in modern society. The many and fundamental argumentative complications that they raise have not received proportional attention in argumentation studies so far. A prominent exception is a recent book by Douglas Walton, devoted entirely to arguments involving expert opinion (Walton, 1997). Confronting some examples from the field of Science and Society with Walton's earlier work, the need can be traced for a more elaborate and sophisticated treatment (...) of the many issues involved, particularly for the model of information seeking dialogue and the treatment of source reasoning. With these issues as points of reference, it is examined in what way this challenge has been taken up in the new book. A few further additions are suggested. (shrink)

Building on the strengths of the first edition, the second edition of the Irwin Nicomachean Ethics features a revised translation (with little editorial intervention), expanded notes (including a summary of the argument of each chapter), an expanded Introduction, and a revised glossary.

This volume gives a theoretical account of the problem of analyzing and evaluating argumentative discourse. After placing argumentation in a communicative perspective, and then discussing the fallacies that occur when certain rules of communication are violated, the authors offer an alternative to both the linguistically-inspired descriptive and logically-inspired normative approaches to argumentation. The authors characterize argumentation as a complex speech act in a critical discussion aimed at resolving a difference of opinion. The various stages of a critical discussion are outlined, (...) and the communicative and interactional aspects of the speech acts performed in resolving a simple or complex dispute are discussed. After dealing with crucial aspects of analysis and linking the evaluation of argumentative discourse to the analysis, the authors identify the fallacies that can occur at various stages of discussion. Their general aim is to elucidate their own pragma- dialectical perspective on the analysis and evaluation of argumentative discourse, bringing together pragmatic insight concerning speech acts and dialectical insight concerning critical discussion.

The Oxford Translation of Aristotle was originally published in 12 volumes between 1912 and 1954. It is universally recognized as the standard English version of Aristotle. This revised edition contains the substance of the original Translation, slightly emended in light of recent scholarship three of the original versions have been replaced by new translations and a new and enlarged selection of Fragments has been added. The aim of the translation remains the same: to make the surviving works of Aristotle readily (...) accessible to English speaking readers. (shrink)

What is a hypocrite? What role does hypocrisy play in our lives? Why is it thought to be such an ugly vice? Is it ever acceptable? What do we lose in our indifference to it? Hypocrisy: Ethical Investigations seeks to illuminate the concept of hypocrisy by exploring its multiple roles in our moral and political lives and struggles. The authors provide a critical examination of a wide range of perspectives on the nature, varieties, and significance of hypocrisy, arguing that it (...) is a key concept in the investigation of the field of morality in general, including its moralizing excesses.

Walton gives a clear method for analyzing and evaluating cases of ad hominem arguments found in everyday argumentation.

A new pragmatic approach, based on the latest developments in argumentation theory, analyzing appeal to expert opinion as a form of argument. Reliance on authority has always been a common recourse in argumentation, perhaps never more so than today in our highly technological society when knowledge has become so specialized—as manifested, for instance, in the frequent appearance of "expert witnesses" in courtrooms. When is an appeal to the opinion of an expert a reasonable type of argument to make, and when (...) does it become a fallacy? This book provides a method for the evaluation of these appeals in everyday argumentation. Specialized domains of knowledge such as science, medicine, law, and government policy have gradually taken over as the basis on which many of our rational decisions are made daily. Consequently, appeal to expert opinion in these areas has become a powerful type of argument. Challenging an argument based on expert scientific opinion, for example, has become as difficult as it once was to question religious authority. Walton stresses that even in cases where expert opinion is divided, the effect of it can still be so powerful that it overwhelms an individual's ability to make a decision based on personal deliberation of what is right or wrong in a given situation. The book identifies the requirements that make an appeal to expert opinion a reasonable or unreasonable argument. Walton's new pragmatic approach analyzes that appeal as a distinctive form of argument, with an accompanying set of appropriate critical questions matching the form. Throughout the book, a historical survey of the key developments in the evolution of the argument from authority, dating from the time of the ancients, is given, and new light is shed on current problems of "junk science" and battles between experts in legal argumentation.

Appeals to emotion—pity, fear, popular sentiment, and _ad hominem_ attacks—are commonly used in argumentation. Instead of dismissing these appeals as fallacious wherever they occur, as many do, Walton urges that each use be judged on its merits. He distinguished three main categories of evaluation. First, is it reasonable, even if not conclusive, as an argument? Second, is it weak and therefore open to critical questioning for argument? And third, is it fallacious? The third category is a strong charge that incurs (...) a critical burden to back it up by citing evidence from the given text and context of dialogue. Walton uses fifty-six case studies to demonstrate that the problem of emotional fallacies is much subtler than has been previously believed. Ranging over commercial advertisements, political debates, union-management negotiations, and ethical disputes, the case studies reveal that these four types of appeals, while based on presumptive reasoning that are tentative and subject to default, are not always or necessarily fallacious types of argumentation.

Following an approach that is empirical but not psychological, and dialectical but not dialogical, in this book Maurice Finocchiaro defines concepts such as reasoning, argument, argument analysis, critical reasoning, methodological reflection, judgment, critical thinking, and informal logic. Including extended critiques of the views of many contemporary scholars, he also integrates into the discussion Arnauld's Port-Royal Logic, Gramsci's theory of intellectuals, and case studies from the history of science, particularly the work of Galileo, Newton, Huygens, and Lavoisier.

This is an introductory guide to the basic principles of constructing good arguments and criticizing bad ones. It is nontechnical in its approach, and is based on 150 key examples, each discussed and evaluated in clear, illustrative detail. The author explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound argument strategies for reasoned persuasion and critical questions for responding. Among the many subjects covered are: techniques of posing, (...) replying to, and criticizing questions, forms of valid argument, relevance, appeals to emotion, personal attack, uses and abuses of expert opinion, problems in deploying statistics, loaded terms, equivocation, and arguments from analogy.

The word 'hypocrisy' has its root in the classical Greek verb 'hupokrinesthai', 'to answer'. In Attic Greek, the verb could mean 'to speak in dialogue' and hence 'to play a part on the stage'. From here it was a short route to the 'hypokrisia' with which the Pharisees are charge in the Gospel of St. Matthew. Accusations of hypocrisy are surprisingly common in our culture, both at the personal and the political level. Judith Shklar goes so far as to characterise (...) our age as that in which 'hypocrisy...alone is...inexcusable'. But, perhaps equally surprisingly, the nature of hypocrisy is hard to grasp. In this paper, we shall suggest that recent discussion of hypocrisy has foundered through a failure to recognise distinct forms of hypocrisy. We shall outline these different forms, and then consider various views on what they have in common. (shrink)
