Fallacies and Argument Appraisal presents an introduction to the nature, identification, and causes of fallacious reasoning, along with key questions for evaluation. Drawing from the latest work on fallacies as well as some of the standard ideas that have remained relevant since Aristotle, Christopher Tindale investigates central cases of major fallacies in order to understand what has gone wrong and how this has occurred. Dispensing with the approach that simply assigns labels and brief descriptions of fallacies, Tindale provides fuller treatments (...) that recognize the dialectical and rhetorical contexts in which fallacies arise. This volume analyzes major fallacies through accessible, everyday examples. Critical questions are developed for each fallacy to help the student identify them and provide considered evaluations.

In this article I explore two accounts of the Fallacy of Many Questions made famous by the question "Have you stopped beating your wife?" The accounts are from the works of Lennart Aqvist and Noel Belnap, and the two authors differ in their accounts of the fallacy. Then I give my own account based on understanding a facet of erotetic logic, i. e., the logic of questions.

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)

A major purpose of this book is to make the post-Hamblin work on fallacies available to a wider audience in a single, convenient volume.

Several of the so-called “fallacies” in Aristotle are not in fact mistaken inference-types, but mistakes or breaches of rules in the questioning games which were practiced in the Academy and in the Lyceum. Hence the entire Aristotelian theory of “fallacies” ought to be studied by reference to the author's interrogative model of inquiry, based on his theory of questions and answers, rather than as a part of the theory of inference. Most of the “fallacies” mentioned by Aristotle can in fact (...) be diagnosed by means of the interrogative model, including petitio principii, multiple questions, “babbling’, etc., and so can Aristotle's alleged anticipation of the fallacy of argumentum ad hominem. The entire Aristotelian conception of inquiry is an interrogative one. Deductive conclusions caught Aristotle's attention in the form of answers that every rational interlocutor must give, assuming only his own earlier answers. Several features of Aristotle's methodology can be understood by means of the interrogative model, including the role of endoxa in it. Theoretically, there is also considerable leeway as to whether “fallacies” are conceived of as mistakes in questioning or as breaches of the rules that govern questioning games. (shrink)

This section aims to summarize and conclude Part I in the form of a taxonomy of legitimate and illegitimate corporate moral responsibility attributions. I believe we can categorise four types of corporate moral responsibility attributions two of which are legitimate and two which are illegitimate with regard to our concept of moral agency and our moral intuition of fairness.

This chapter focuses on one of the common fallacies in Western philosophy: the moralistic fallacy. The moralistic fallacy occurs when one concludes that something is a particular way because it should or ought to be that way. Alternatively, this fallacy occurs when one concludes that something cannot be a particular way because it should not or ought not be that way. The moralistic fallacy is often described as the reverse of the is/ought fallacy, wherein one (...) reasons fallaciously that because things are a particular way, they ought to be that way. Variations of the moralistic fallacy occur whenever any normative claim is used to justify a factual claim about the world, and so the pattern of fallacious reason central to the moralistic fallacy can also be found in legal reasoning, prudential reasoning, or reasoning regarding proper etiquette, aesthetics, humor, or appropriate emotional responses. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called 'naturalistic fallacy'. The naturalistic fallacy follows from one's metaphysical (metaethical) commitments rather than simply a general defect of reasoning. Unlike many fallacies – formal or informal – it is not likely that one will find the naturalistic fallacy in standard logic textbooks. The natural properties (e.g., pleasure) are logically and/or metaphysically distinct from normative or moral properties (e.g., goodness) and, thus, any identification of a (...) natural property with a normative property would be defective. G.E. Moore's metaphysics of values (metaethics) disallows any movement from natural to non‐natural properties. He thinks of normative properties/objects as logically and metaphysically distinct from non‐natural properties/objects. Yet if one rejects the wider non‐naturalistic moral realism central to Moore's naturalistic fallacy, it seems possible to accept a movement from the natural to normative. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy, 'intentional fallacy (IF)'. The IF is an odd kind of fallacy. Rather than being a fallacy focused on logic and argumentation, it is a fallacy that focuses on art, relating to how we judge art and engage in literary criticism. The IF focuses on the fact that we often think that there is one right interpretation of a work of art. According to David Fenner, (...) the IF “states that we do not need to know, nor can we on most occasions, what was in the mind of the artist in order to interpret the art work”. So, it seems unreasonable to use the artist's intention as the most important way to understand a work of art as the artist's intention is often unavailable. The IF is an error in art interpretation that causes us to realize important things about art. (shrink)

In the pragma-dialectical approach, fallacies are considered incorrect moves in a discussion for which the goal is successful resolution of a dispute. Ten rules are given for effective conduct at the various stages of such a critical discussion (confrontation, opening, argumentation, concluding). Fallacies are discussed as violations of these rules, taking into account all speech acts which are traditionally recognized as fallacies. Special attention is paid to the role played by implicitness in fallacies in everyday language use. It is stressed (...) that identifying and acknowledging fallacies in ordinary discussions always has a conditional character. Differences between the pragma-dialectical perspective, the Standard Treatment, and the formal logic approach to fallacy analysis are discussed. (shrink)

Fallacies are things people commit, and when they commit them they do something wrong. What kind of activities are people engaged in when they commit fallacies, and in what way are they doing something wrong? Many different things are called fallacies. The diversity of the use of the concept of a fallacy suggests that we are dealing with a family of cases not related by a common essence. However, we suggest a simple account of the nature of fallacies which (...) encompasses them all, viz., the term “fallacy” is our most general term for criticizing any general procedure used for the fixation of beliefs that has an unacceptably high tendency to generate false or unfounded beliefs, relative to that method of fixing beliefs. Very different sorts of things called fallacies are examined in the light of this account, e.g., denying the antecedent, circular arguments, so-called informal fallacies, and propositions said to be fallacies. We do not provide a theory of fallacies. Still, on our account pretty much all of those things that have been called fallacies are fallacies, and they have been called fallacies for pretty much the same reasons. (shrink)

Fallacies are the ‘ideal types of improper inference’, named only because they represent a common or seductive error. Naming them facilitates identification (reducing ‘false negatives’ in argument evaluation), but increases the risk of false positives; it is essentially a cost-effectiveness issue whether to introduce a new name. Statistical fallacies include errors of elementary experimental design, but also conceptual confusions, e.g. of cause with correlation, of association with guilt, where an illicit substitution is made. The focus here is on recent nationwide (...) efforts to replace criteria of merit with correlates of success, in the evaluation of teaching. This involves a number of mistakes, including ‘precipitate decision’, confusing the normative with the descriptive, and using minimax when optimizing or maximin is appropriate, as well as various legal and ethical blunders.

The basic question of this monograph is: how should we go about judging arguments to be reasonable or unreasonable? Our concern will be with argument in a broad sense, with realistic arguments in natural language. The basic object will be to engage in a normative study of determining what factors, standards, or procedures should be adopted or appealed to in evaluating an argument as "good," "not-so-good," "open to criticism," "fallacious," and so forth. Hence our primary concern will be with the (...) problems of how to criticize an argument, and when a criticism is reasonably justified. (shrink)

We are happy to present to the reader the first book of our Applied Logic Series. Walton's book on the fallacies of ambiguity is firmly at the heart of practical reasoning, an important part of applied logic. There is an increasing interest in artifIcial intelligence, philosophy, psychol ogy, software engineering and linguistics, in the analysis and possible mechanisation of human practical reasoning. Continuing the ancient quest that began with Aristotle, computer scientists, logicians, philosophers and linguists are vigorously seeking to deepen (...) our understanding of human reasoning and argumentation. Significant communities of researchers are actively engaged in developing new approaches to logic and argumentation, which are better suited to the urgent needs of today's applications. The author of this book has, over many years, made significant contributions to the detailed analysis of practical reasoning case studies, thus providing solid foundations for new and more applicable formal logical systems. We welcome Doug Walton's new book to our series. (shrink)

This paper offers a solution to the problem of understanding how a fallacious argument can be deceptive by “seeming to be valid”, or (better) appearing to be a better argument of its kind than it really is. The explanation of how fallacies are deceptive is based on heuristics and paraschemes. Heuristics are fast and frugal shortcuts to a solution to a problem that sometimes jump to a conclusion that is not justified. In fallacious instances, according to the theory proposed, this (...) jump overlooks prerequisites of the defeasible argumentation scheme for the type of argument in question. Three informal fallacies, argumentum ad verecundiam , argumentum ad ignorantiam and fear appeal argument, are used to illustrate and explain the theory. (shrink)

Robert Kimball, in “What’s Wrong with Argumentum Ad Baculum?” (Argumentation, 2006) argues that dialogue-based models of rational argumentation do not satisfactorily account for what is objectionable about more malicious uses of threats encountered in some ad baculum arguments. We review the dialogue-based approach to argumentum ad baculum, and show how it can offer more than Kimball thinks for analyzing such threat arguments and ad baculum fallacies.

The claim that we have a moral obligation, where a choice can be made, to bring to birth the 'best' child possible, has been highly controversial for a number of decades. More recently Savulescu has labelled this claim the Principle of Procreative Beneficence. It has been argued that this Principle is problematic in both its reasoning and its implications, most notably in that it places lower moral value on the disabled. Relentless criticism of this proposed moral obligation, however, has been (...) unable, thus far, to discredit this Principle convincingly and as a result its influence shows no sign of abating. I will argue that while criticisms of the implications and detail of the reasoning behind it are well founded, they are unlikely to produce an argument that will ultimately discredit the obligation that the Principle of Procreative Beneficence represents. I believe that what is needed finally and convincingly to reveal the fallacy of this Principle is a critique of its ultimate theoretical foundation, the notion of impersonal harm. In this paper I argue that while the notion of impersonal harm is intuitively very appealing, its plausibility is based entirely on this intuitive appeal and not on sound moral reasoning. I show that there is another plausible explanation for our intuitive response and I believe that this, in conjunction with the other theoretical criticisms that I and others have levelled at this Principle, shows that the Principle of Procreative Beneficence should be rejected.

The paper argues that the two best known formal logical fallacies, namely denying the antecedent (DA) and affirming the consequent (AC) are not just basic and simple errors, which prove human irrationality, but rather informational shortcuts, which may provide a quick and dirty way of extracting useful information from the environment. DA and AC are shown to be degraded versions of Bayes’ theorem, once this is stripped of some of its probabilities. The less the probabilities count, the closer these fallacies (...) become to a reasoning that is not only informationally useful but also logically valid. (shrink)

Fallacies A fallacy is a kind of error in reasoning. The list of fallacies below contains 230 names of the most common fallacies, and it provides brief explanations and examples of each of them. Fallacious arguments should not be persuasive, but they too often are. Fallacies may be created unintentionally, or they may be created … Continue reading fallacies →.

Connecting research and production, art research represents a breaking of the barrier between creation and academia. However, there is also a contradiction contained in this kind of research deriving from its methods, since the process of art-based practice must, by its very nature, involve the subjectivity of the artist. I use my own studies as the research object to discuss this issue, and this article presents the problems I encountered during my artistic practice and research of ambiguous roles. This paper (...) has two main points of focus. First, I explore how the fallacy of self-referentiality is presented in paintings and films, and, second, I draw on my short film practice during my master’s study period to explain how the shots present a continuum in relation to the “absent one” and produce interface effects. However, the second point is not necessarily the result of the first one. This kind of connection and contradiction between practice and cognition in the process of art research is that I will analyse and discuss here. (shrink)

Why are some arguments fallacious? Since argumentation is an intellectual activity that can be performed better or worse, do we evaluate arguments simply in terms of their content, or does it also make sense to evaluate the arguer in light of the content put forward? From a ‘virtue’ approach, I propose understanding fallacies as having some link with intellectual vice. Drawing from recent work by Paul Grice, Linda Zagzebski, Andrew Aberdein, and Douglas Walton, this essay argues that if there is (...) some sense of argumentation where an argument is truth-propagating and not put forward in order to ‘win’, fallacies may be the vicious element in arguments that undermines, most often because the arguer’s goal is only. From this perspective, fallacies may not only be improper ‘moves’ in an argument, but may also reveal something lacking in the arguer’s intellectual character. (shrink)

The paper examines Walton‘s concept of fallacy as it develops throughthree stages of his work: from the early series of papers co-authored withJohn Woods; through a second phase of involvement with thepragma-dialectical perspective; and on to the final phase in which heoffers a distinct pragmatic theory that reaches beyond the perceived limitsof the pragma-dialectical account while still exhibiting a debt to thatperspective and the early investigations with Woods. It is observed how Walton‘s model of fallacy is established in (...) distinction to its competitors,and its various problems and successes are discussed. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called 'genetic fallacy' (GnF). One commits the GnF when advocating for a conclusion based solely on origin. This is a fallacy of relevance—irrelevance, really—because the origin of a claim may be irrelevant to its truth‐value. That is to say, providing an account of the genesis of a claim, its history or origin, may be informative and helpful; however, it need not determine the truth‐value of the claim. (...) Therefore, when one draws a conclusion regarding the truth‐value of a claim based solely on the origin of the claim, then one may have committed the GnF. In the ethical language of “means and ends” reasoning, GnF helps to highlight the problematic nature of the utilitarian‐style disconnect between the justice of actions and the goodness of their consequences.

Van Eemeren and Houtlosser view fallacies as “derailments of strategic maneuvering” that go against a norm for critical reasonableness. What is to happen if such a derailment is perceived to have taken place? Krabbe (2003) and Jacobs (2000) have discussed the possibilities for continuing the argumentative exchange in a constructive way. Starting from their proposals, van Eemeren and Houtlosser argue that the party who observes that something has gone wrong should maneuver in such a way that at the same time (...) the derailment is recognized and a “re-railment” takes place that brings the discussion back on track. This means that then a meta-dialogue or sub-discussion develops in which the alleged fallacy is responded to and readjusted appropriately. Although this solution has something in common with both Krabbe’s proposal and Jacobs’ proposal, it differs from Krabbe’s proposal because it does not result in just retracting or maintaining the alleged fallacy and it differs from Jacobs’ proposal because it does not allow for making a move that has the appearance of a counter-fallacy.

The paper critically investigates the pragma-dialectics of van Eemeren and Grootendorst, particularly the treatment of fallacies. While the pragma-dialectieians claim that dialectics combines the logical and rhetorical approaches to argumentation, it is argued here that the perspective relies heavily on rhetorical features that have been suppressed in the account and that overlooking these features leads to significant problems in the pragma-dialectical perspective. In light of these problems, the author advocates turning attention to a rhetorical account which subsumes the logical and (...) dialectical. (shrink)

The public must make assessments of a range of health-related issues. However, these assessments require scientific know-ledge which is often lacking or ineffectively utilized by the public. Lay people must use whatever cognitive resources are at their disposal to come to judgement on these issues. It will be contended that a group of arguments—so-called informal fallacies—are a valuable cognitive resource in this regard. These arguments serve as cognitive heuristics which facilitate reasoning when knowledge is limited or beyond the grasp of (...) reasoners. The results of an investigation into the use of these arguments by the public are reported. (shrink)

The view that we live in the Anthropocene is increasingly gaining currency across scientific disciplines. Especially in sociology this is said to require a paradigm shift in analysis and theory formation. This article argues that such a conclusion is premature. Owing to a scholastic fallacy – the uncritical transposition of the concept from the natural to the social sciences – Anthropocene lacks analytic clarity and explanatory power evidenced by: a normative overreach that erroneously imagines an idealised world citizenry with (...) collective action capacities; an obfuscation of the unequal distribution of ecological pathologies caused by capitalism; a normative indeterminacy concerning modes of redress; and an abstract ecological universalism offered as moral panacea. The article suggests that sociology needs to address the Anthropocene’s heterogeneity marked by contradictory regional interests and inequalities that neither appeals to social justice or ‘one humanity’ nor an escape into a dissolution of ontological differences between actors and artefacts can redeem. To that end, sociologists are asked to undertake a critical reconstruction of the concept. (shrink)

The so-called New Theory of Reference (Marcus, Kripke etc.) is inspired by the insight that in modal and intensional contexts quantifiers presuppose nondescriptive unanalyzable identity criteria which do not reduce to any descriptive conditions. From this valid insight the New Theorists fallaciously move to the idea that free singular terms can exhibit a built-in direct reference and that there is even a special class of singular terms (proper names) necessarily exhibiting direct reference. This fallacious move has been encouraged by a (...) mistaken belief in the substitutional interpretation of quantifiers, by the myth of thede re reference, and a mistaken assimilation of direct reference to ostensive (perspectival) identification. Thede dicto vs.de re contrast does not involve direct reference, being merely a matter of rule-ordering (scope).The New Theorists' thesis of the necessity of identities of directly referred-to individuals is a consequence of an unmotivated and arbitrary restriction they tacitly impose on the identification of individuals.

Presuppositions are at the same time a crucial and almost neglected dimension of arguments and fallacies. Arguments involve different types of presuppositions, which can be used for manipulative purposes in distinct ways. However, what are presuppositions? What is their dialectical function? Why and how can they be dangerous? This paper intends to address these questions by developing the pragmatic approaches to presupposition from a dialectical perspective. The use of presuppositions will be analyzed in terms of presumptive conclusions concerning the interlocutor’s (...) acceptance of a proposition, which can be assessed as reasonable or unacceptable. Their dialectical function is described in terms of dark side commitments attributed to a collective "voice" representing what is commonly shared. For this reason, they count as attempts to include the presupposed contents into the hearer’s commitment store, which in some circumstances can reverse the burden of proof. The different manipulative strategies grounded on controversial presuppositions will be examined by showing the distinct roles that the latter play and the relationship between the degrees of presuppositional implicitness and the speaker’s burden of retraction.

This chapter focuses on one of the common fallacies in Western philosophy: definist fallacy. The definist fallacy consists of (1) defining one concept in terms of another concept with which it is not clearly synonymous, (2) as the persuasive definition fallacy, defining a concept in terms of another concept in an infelicitous way that is favorable to one's position, or (3) the insistence that a term be defined before it can be used in discussion. The simplest way (...) to not commit any version of this fallacy is to define one's terms credibly! He/she needs to avoid using definitions that are laden with emotion or those that are idiosyncratic. That is, he/she may use more neutral and accepted definitions. If those definitions seem inadequate for his/her purposes, then he/she may argue for his/her definition. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy, etymological fallacy (EF). To understand the EF fully, it is important to break down the word etymology, which is a practice that in itself informs the conversation surrounding the fallacy. EF is a willful use of a former definition of a word that has changed meaning and/or developed new connotations because the change does not benefit the one committing the fallacy. To avoid committing the EF, (...) individuals should approach language as they would a scientific process: they may hypothesize the word means X, but after further research and consideration, realize that indeed a word now means Y. Either way, the changing nature of language must be considered and individuals should be learned enough and flexible enough to communicate within the time and culture they inhabit. Clinging to etymons while ignoring the evolution and everyday use of language is neither logical nor truthful. (shrink)

The ad baculum is not a fallacy in an argument, but is offered instead of an argument to put an end to further argument. This claim is the basis for criticizing Michael Wreen's "neo-traditionalism," which yields misreadings of supposed cases of the ad baculum because of its rejection of any consideration of what the person using the ad baculum, or someone who refers to that use as an "argument," is doing. The paper concludes with reflections on the values that (...) should inform talk of a fallacy in an argument such as the one that Wreen is giving. (shrink)

To demonstrate that a fallacy is committed, Block needs to convince us of two things: first, that the concept of phenomenal consciousness is distinct from that of access consciousness, and second, that it picks out a different property from that of access consciousness. I raise doubt about both of these claims, suggesting that the concept of a phenomenal property is the concept of a property to which we have a special sort of access.

Milton Friedman's article, The Social Responsibility of Business Is To Increase Its Profits, owes its appeal to the rhetorical devices of simplicity, authority, and finality. More careful consideration reveals oversimplification and ambiguity that conceals empirical errors and logical fallacies. It is false that business does, or would, operate exclusively in economic terms, that managers concentrate obsessively on profitability, and that ethics can be marginalized. These errors reflect basic contradictions: an apolitical political base, altruistic agents of selfishness, and good deriving from (...) greed. (shrink)

We analyze the “Logical fallacies and reasonable debates in invasion biology: a response to Guiaşu and Tindale” article by Frank et al., and also discuss this work in the context of recent intense debates in invasion biology, and reactions by leading invasion biologists to critics of aspects of their field. While we acknowledge the attempt by Frank et al., at least in the second half of their paper, to take into account more diverse points of view about non-native species and (...) their complex roles in ecosystems, we also find the accusations of misrepresenting invasion biology, for instance by “cherry-picking” and “constructing ‘straw people’”, directed at the Guiaşu and Tindale study to be unwarranted. Despite the sometimes harsh responses by leading invasion biologists to critics of their field, we believe that persistent and fundamental problems remain in invasion biology, and we discuss some of these problems in this article. Failing to recognize these problems, and simply dismissing or minimizing legitimate criticisms, will not advance the cause, or enhance the general appeal, of invasion biology and will prevent meaningful progress in understanding the multiple contributions non-native species can bring to various ecosystems worldwide. We recommend taking a more open-minded and pragmatic approach towards non-native species and the novel ecosystems they are an integral part of. (shrink)

In this paper I will attempt a unified analysis of the various examples of the fallacy of accident given by Aristotle in the Sophistical Refutations. In many cases the examples underdetermine the fallacy and it is not trivial to identify the fallacy committed. To make this identification we have to find some error common to all the examples and to show that this error would still be committed even if those other fallacies that the examples exemplify were (...) not. Aristotle says that there is only one solution “against the argument” as opposed to “against the man”, and it is this solution the paper attempts to find. It is a characteristic mark of my analysis that some arguments that we might normally be inclined to say are fallacious turn out to be valid and that some arguments that we would normally be inclined to say are valid turn out to be fallacious. This is (in part) because what we call validity in modern logic is not the same as the apodicticity that Aristotelian syllogisms require in order to be used in science. The fallacies of accident, uniquely among the fallacies, are failures of apodicticity rather than failures of, in particular, semantic entailment. This makes sense in a tensed and token-based logic such as Aristotle’s. I conclude that the closest analogue to the fallacy of accident that we can point to is a fallacy in modal logic, viz., the fallacy of necessity. (shrink)

Begging the question — roughly, positing in the premises what is to be proved in the conclusion — is a perplexing fallacy.1 Are not question-begging arguments valid? Yes, we may find ourselves saying, but they are fallacious despite their validity, owing to their inability to establish the truth of a conclusion which is not already known. But are not question-begging arguments sometimes effective in bringing an audience to an awareness of the truth of the conclusion? How can a dialectical (...) maneuver which is capable of effecting epistemic progress be a fallacy, an illegitimate maneuver? In such cases of success, we can reply, the audience was simply in need of some logical coaching — a question-begging argument is of its very nature ill-suited for producing new knowledge in someone who is being fully rational. But then are not all valid arguments question-begging, since the conclusions are at least implicitly contained in the premises in such a way that a fully rational individual can never augment his knowledge through such arguments? No, we may answer, only those valid arguments in which the proposition constituting the conclusion appears, whether distinguised or not, as a distinct premise are question-begging; if several premises go together to imply a conclusion, the argument does not beg the question, But why is it legitimate to posit premises which more-or-less implicitly contain the conclusion, while it is illegitimate to posit premises which more-or-less explicitly contain the conclusion? Because, we are tempted to say, a question-begging argument is one in which what is to be proved in the conclusion is posited in the premises, and this positing must be more-or-less explicit in order for a fallacy to be committed!

In this article, we address fallacious analogical reasoning and the Metaphoric Fallacy to a Deductive Inference (MFDI), recently discussed by B. Lightbody and M. Berman (2010). We claim that the authors’ proposal to introduce a new fallacy is only partly justified. We also argue that, in some relevant cases, fallacious analogical reasoning involving metaphors is only affected by the use of quaternio terminorum.
