One result of successful argumentation – able arguers presenting cogent arguments to competent audiences – is a transfer of credibility from premises to conclusions. From a purely logical perspective, neither dubious premises nor fallacious inference should lower the credibility of the target conclusion. Nevertheless, some arguments do backfire this way. Dialectical and rhetorical considerations come into play. Three inter-related conclusions emerge from a catalogue of hapless arguers and backfiring arguments. First, there are advantages to paying attention to arguers and their (...) contexts, rather than focusing narrowly on their arguments, in order to understand what can go wrong in argumentation. Traditional fallacy identification, with its exclusive attention to faulty inferences, is inadequate to explain the full range of argumentative failures. Second, the notion of an Ideal Arguer can be defined by contrast with her less than ideal peers to serve as a useful tool in argument evaluation. And third, not all of the ways that arguers raise doubts about their conclusions are pathological. On the contrary, some ways that doubts are raised concerning our intended conclusions are an integral part of ideal argumentative practice. (shrink)

Beginning with a discussion of the Informal Logic Movement and the renewed interest in critical thinking in education, this book critically assesses the work of Robert Ennis, Richard Paul and John McPeck.

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.

Assuming that critical thinking dispositions are at least as important as critical thinking abilities, Ennis examines the concept of critical thinking disposition and suggests some criteria for judging sets of them. He considers a leading approach to their analysis and offers as an alternative a simpler set, including the disposition to seek alternatives and be open to them. After examining some gender-bias and subject-specificity challenges to promoting critical thinking dispositions, he notes some difficulties involved in assessing critical thinking dispositions, and (...) suggests an exploratory attempt to assess them.

Virtue theories have become influential in ethics and epistemology. This paper argues for a similar approach to argumentation. Several potential obstacles to virtue theories in general, and to this new application in particular, are considered and rejected. A first attempt is made at a survey of argumentational virtues, and finally it is argued that the dialectical nature of argumentation makes it particularly suited for virtue theoretic analysis.

Philoctetes was a good man and a good soldier. When he was on his way to Troy to fight alongside the Greeks, he had a terrible misfortune. By sheer accident he trespassed in a sacred precinct on the island of Lemnos. As punishment he was bitten on the foot by the serpent who guarded the shrine. His foot began to ooze with foul-smelling pus, and the pain made him cry out curses that spoiled the other soldiers' religious observances. They therefore (...) left him alone on the island, a lame man with no resources but his bow and arrows, no friends but the animals who were also his food. Ten years later, according to Sophocles' version of the story, they come to bring him back: for they have learned that they cannot win the war without him. The leaders of the expedition think of Philoctetes as a tool of their purposes; they plan to trick him into returning, with no empathy for his plight. The Chorus of soldiers, however, has a different response. Even before they see the man, they imagine vividly what it is like to be him– and they enter a protest against the callousness of the commanders: For my part, I pity him– thinking of how, with no living soul to care for him, seeing no friendly face, wretched, always alone, he suffers with a fierce affliction, and has no resources to meet his daily needs. How in the world does the poor man survive? (shrink)

In this paper, the authors argue for two main claims: first, that the epistemic results of group deliberation can be superior to those of individual inquiry; and, second, that successful deliberative groups depend on individuals exhibiting deliberative virtues. The development of these group-deliberative virtues, the authors argue, is important not only for epistemic purposes but political purposes, as democracies require the virtuous deliberation of their citizens. Deliberative virtues contribute to the deliberative synergy of the group, not only in terms of (...) improving the quality of the group's present decisions, but also improving the background conditions for continued group deliberation. The authors sketch a preliminary schedule of these group-deliberative virtues modelled on Aristotle's conception of virtue as the mean between two extreme vices. The virtues discussed in this article include deliberative wit, friendliness, empathy, charity, temperance, courage, sincerity, and humility. (shrink)

Francis Bacon, lawyer, statesman, and philosopher, remains one of the most effectual thinkers in European intellectual history. We can trace his influence from Kant in the 1700s to Darwin a century later. The Advancement of Learning , first published in 1605, contains an unprecedented and thorough systematization of the whole range of human knowledge. Bacon’s argument that the sciences should move away from divine philosophy and embrace empirical observation would forever change the way philosophers and natural scientists interpret their world.

Virtue argumentation theory has been charged of being incomplete, given its alleged inability to account for argument cogency in virtue-theoretical terms. Instead of defending VAT against that challenge, I suggest it is misplaced, since it is based on a premise VAT does not endorse, and raises an issue that most versions of VAT need not consider problematic. This in turn allows distinguishing several varieties of VAT, and clarifying what really matters for them.

If good argument is virtuous, then fallacies are vicious. Yet fallacies cannot just be identified with vices, since vices are dispositional properties of agents whereas fallacies are types of argument. Rather, if the normativity of good argumentation is explicable in terms of virtues, we should expect the wrongness of fallacies to be explicable in terms of vices. This approach is defended through case studies of several fallacies, with particular emphasis on the ad hominem.

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.

In his influential work on critical argumentation, Douglas Walton explains how to judge whether an argumentum ad verecundiam is fallacious or legitimate. He provides six critical questions and a number of ancillary sub-questions to guide the identification of reasonable appeals to authority. While it is common for informal logicians to acknowledge the role of bias in sampling procedures and hypothesis confirmation , there is a conspicuous lack of discourse on the effect of identity prejudice on judgments of authority, even though (...) this is a well-documented factor in attributing credibility, expertise, trustworthiness, and professional competence to oppressed groups. This could result in faulty judgments of ad verecundiam fallacy. Focusing on gender bias, I review recent works in feminist epistemology—particularly those of Miranda Fricker and Helen Longino —to develop three gender-based critical questions to supplement Walton’s original list of six. This addition will help us to identify erroneous dismissals of appeals to authority based on epistemic injustice and epistemic irresponsibility on the part of the speaker or knowledge community. This project promotes the overlapping aims of feminist epistemology and informal logic. (shrink)

The notion that concern for the feelings of animals is as such sentimental is rather a common one. I shall suggest that, in general, the charge of sentimentality can never be made to stick in this way merely because concern is directed towards one class of sentient beings rather than another. It rests on the motives and reasons for being concerned, not on the objects to which concern is directed. About animals, however, a special point arises which I must deal (...) with first. Objectors may say that it is sentimental to attribute feelings to them at all, or at least to attribute specific feelings, to suppose ourselves well enough informed about their states of consciousness for concern to be appropriate. The charge of sentimentality here is close to that of anthropomorphism. (shrink)

A dialogue-based analysis of informal fallacies does not provide a fully adequate explanation of our intuitions about what is wrong with ad baculum and of when it is admissible and when it is not. The dialogue-based analysis explains well why mild, benign threats can be legitimate in some situations, such as cooperative bargaining and negotiation, but does not satisfactorily account for what is objectionable about more malicious uses of threats to coerce and to intimidate. I propose an alternative deriving partly (...) from virtue theory in ethics and epistemology and partly from Kantian principles of respect for persons as ends-in-themselves. I examine some specific kinds of social relations, e.g., parent-child and partner relationships, and ask what kinds of threats are permissible in these relationships and especially what is wrong with the objectionable threats. My explanation is framed in terms of the good character and contributing virtues of the ideal parent or partner on the one hand, and the bad character and contributing vices of the abusive parent or violent partner on the other. This analysis puts the discussion of theats in the context of virtue theory, of human flourishing, and of the kind of social relations it is best to have. In general, what's wrong with argumentum ad baculum should be explained in terms of the intentions, purposes, and character of threateners, and the differences in intentions and purposes for which threats are made. The characters of those who make the threats will provide the criteria for distinguishing benign and malicious threats. (shrink)

Several authors have recently begun to apply virtue theory to argumentation. Critics of this programme have suggested that no such theory can avoid committing an ad hominem fallacy. This criticism is shown to trade unsuccessfully on an ambiguity in the definition of ad hominem. The ambiguity is resolved and a virtue-theoretic account of ad hominem reasoning is defended.

This is a critical appreciation of Govier’s 2006 ISSA keynote address on the fallacy of composition, and of economists’ writings on this fallacy in economics. I argue that the “fallacy of composition” is a problematical concept, because it does not denote a distinctive kind of argument but rather a plurality, and does not constitute a distinctive kind of error, but rather reduces to oversimplification in arguing from micro to macro. Finally, I propose further testing of this claim based on examples (...) involving public vs. private debt in economics; oligarchic tendencies in politics, and the emergence of societal wholes in sociology.
