In some recent literature, ‘whataboutism’ is analysed as a sometimes-reasonable argument or claim about inconsistency on an issue of dispute, akin to the ad hominem tu quoque. We argue that this doesn’t capture the peculiarly meta-argumentative failure (or success) of ‘what-about’ appeals. Whataboutist moves are appeals to evidence about whether one has assessed the total evidence or has made the right contrasting consideration and so need not be failures of consistency on the first order. Consequently, whataboutism is best theorized as (...) a meta-argumentative fallacy. We argue, in light of this observation, whataboutism can come in two forms: the second-personal, which takes inconsistency to be an indicator of meta-argumentative issues, and the third-personal, which makes the case that there is a failure of total evidence.

The fallacy fallacy is either the misdiagnosis of fallacy or the supposition that the conclusion of a fallacy must be a falsehood. This paper explores the relevance of these and related errors of reasoning for the appraisal of arguments, especially within virtue theories of argumentation. In particular, the fallacy fallacy exemplifies the Owl of Minerva problem, whereby tools devised to understand a norm make possible new ways of violating the norm. Fallacies are such tools and so are vices. Hence a (...) similar problem arises with argumentative vices. Fortunately, both instances of the problem have a common remedy. (shrink)

The informal logic movement began as an attempt to develop – and teach – an alternative logic which can account for the real life arguing that surrounds us in our daily lives – in newspapers and the popular media, political and social commentary, advertising, and interpersonal exchange. The movement was rooted in research and discussion in Canada and especially at the University of Windsor, and has become a branch of argumentation theory which intersects with related traditions and approaches (notably formal (...) logic, rhetoric and dialectics in the form of pragma-dialectics). In this volume, some of the best known contributors to the movement discuss their views and the reasoning and argument which is informal logic’s subject matter. Many themes and issues are explored in a way that will fuel the continued evolution of the field. Federico Puppo adds an insightful essay which considers the origins and development of informal logic and whether informal logicians are properly described as a “school” of thought. In considering that proposition, Puppo introduces readers to a diverse range of essays, some of them previously published, others written specifically for this volume. (shrink)

This paper is about bias and ad hominem arguments. It will begin by rehearsing some reasons for thinking that there are both legitimate and illegitimate ad hominems, as well as reasons for thinking that biases can be both justified and unjustified. It will explain that justified biases about people with certain social identities can give rise to both legitimate and illegitimate ad hominem attacks, while unjustified biases only give rise to illegitimate ad hominems. The paper will then describe Audrey Yap’s (...) view that even when an unjustified bias is made explicit and shown to be unjustified, it can still make certain fallacious ad hominem arguments seem persuasive. Finally, it will set out the opposite sort of problem: just as unjustified biases can make fallacious ad hominems seem persuasive even when the bias is made explicit, so too can unjustified biases make legitimate ad hominem arguments seem unpersuasive, even when the bias is made explicit.

Many of us read Peter Singer ’ s work on our obligations to those in desperate need with our students. Famously, Singer argues that we have a moral obligation to give a significant portion of our assets to famine relief. If my own experience is not atypical, it is quite common for students, upon grasping the implications of Singer ’ s argument, to ask whether Singer gives to famine relief. In response it might be tempting to remind students of the (...) ad hominem fallacy of attacking the person advancing an argument rather than the argument itself. In this paper I argue that the “ ad hominem reply ” to students ’ request for information about Singer is misguided. First I show that biographical facts about the person advancing an argument can constitute indirect evidence for the soundness / unsoundness of the argument. Second, I argue that such facts are relevant because they may reveal that one can discard the argument without thereby incurring moral responsibility for failing to act on its conclusion even if the argument is sound.

In order for confrontational strategic manoeuvring, aimed at defining in a reasonable way the difference of opinion to one’s own advantage, to be sound, arguers’ attempt to arrive at a particular definition must not prevent other definitions from coming about. This paper discusses the ad hominem fallacy as an obstruction of the procedure of critical testing as a result of failure to meet this particular soundness conditions.

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.

Pragma-Dialectics (PD) is an approach to argumentation that can be described as disagreement-centric. On PD, disagreement is the condition which defines argument, it is the practical problem to be solved by it, and disagreement’s management is the ultimate source of argument’s normativity. On PD, arguing in the context of agreement is taken to be “incorrect” and arguments where agreement already reigns are “pointless.” Even the PD account of fallacies is disagreement-centered: a fallacy is something that impedes resolution of a dispute. (...) We argue here that the disagreement-focus of PD yields procedural errors of application in cases of arguments given explicitly for agreement-management, that there are explanations of fallacies better understood as agreement-focused (straw man and ad hominem in particular), and that there are unique meta-argumentative errors emergent in instances of agreement.

An agent-centered, goal-directed, resource-bound logic of human reasoning would do well to note that individual cognitive agency is typified by the comparative scantness of available cognitive resources—information, time, and computational capacity, to name just three. This motivates individual agents to set their cognitive agendas proportionately, that is, in ways that carry some prospect of success with the resources on which they are able to draw. It also puts a premium on cognitive strategies which make economical use of those resources. These (...) latter I callscant-resource adjustment strategies,and they supply the context for an analysis of abduction. The analysis is Peircian in tone, especially in the emphasis it places on abduction’signorance-preservingcharacter. My principal purpose here is to tie abduction’s scarce-resource adjustment capacity to its ignorance preservation. (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.

In this paper, we consider the way that web documents seeking to persuade readers of certain science claims provide information about the sources of the arguments. Our quantitative analysis reveals that web documents in our sample include hundreds of examples in which the reader is provided information regarding the trustworthiness of sources. The web documents also contain a large number of examples in which the reader is provided with information about how many individuals hold a particular belief. We discuss ad (...) hominem, ad verecundiam, and ad populum arguments, and the way that the examples found in our sample of documents are related to these argumentation schemes. (shrink)

In IV, xvii, 19–22 of his Essay, Locke employs Latin labels for four kinds of argument, of which one (ad hominem) was already in circulation and one (ad judicium) has never had much currency. The present proposal seeks to locate and clarify what Locke was aiming to describe, and to contrast what he says with some subsequent uses that have been made of these labels as if they named fallacies. Though three of the four kinds of argument that Locke picks (...) out are often less than decisive, he casts no aspersion on the legitimacy of their use in debate. (shrink)

The recent literature on ad hominem argument contends that the speaker’s character is sometimes relevant to evaluating what she says. This effort to redeem ad hominems requires an analysis of character that explains why and how character is relevant. I argue that virtue epistemology supplies this analysis. Three sorts of ad hominems that attack the speaker’s intellectual character are legitimate. They attack a speaker’s: (1) possession of reliabilist vices; or (2) possession of responsibilist vices; or (3) failure to perform intellectually (...) virtuous acts. Legitimate ad hominems conclude that we should not believe what a speaker says solely on her say-so. (shrink)
