Beliefs like the Gambler's Fallacy and the Hot Hand have interested cognitive scientists, economists, and philosophers for centuries. We propose that these judgment patterns arise from the observer's mental models of the sequence-generating mechanism, moderated by the strength of belief in an a priori base rate. In six behavioral experiments, participants observed one of three mechanisms generating sequences of eight binary events: a random mechanical device, an intentional goal-directed actor, and a financial market. We systematically manipulated participants’ beliefs (...) about the base rate probabilities at which different outcomes were generated by each mechanism. Participants judged 18 sequences of outcomes produced by a mechanism with either an unknown base rate, a specified distribution of three equiprobable base rates, or a precise, fixed base rate. Six target sequences ended in streaks of between two and seven identical outcomes. The most common predictions for subsequent events were best described as pragmatic belief updating, expressed as an increasingly strong expectation that a streak of identical signals would repeat as the length of that streak increased. The exception to this pattern was for sequences generated by a random mechanical device with a fixed base rate of.50. Under this specific condition, participants exhibited a bias toward reversal of streaks, and this bias was larger when participants were asked to make a dichotomous choice versus a numerical probability rating. We review alternate accounts for the anomalous judgments of sequences and conclude with our favored interpretation that is based on Rabin's version of Tversky & Kahneman's Law of Small Numbers.

The gambler’s fallacy is the tendency to expect random processes to switch more often than they actually do—for example, to think that after a string of tails, a heads is more likely. It’s often taken to be evidence for irrationality. It isn’t. Rather, it’s to be expected from a group of Bayesians who begin with causal uncertainty, and then observe unbiased data from an (in fact) statistically independent process. Although they converge toward the truth, they do so in an (...) asymmetric way—ruling out “streaky” hypotheses more quickly than “switchy” ones. As a result, the majority (and the average) exhibit the gambler’s fallacy. If they have limited memory, this tendency persists even with arbitrarily-large amounts of data. Indeed, such Bayesians exhibit a variety of the empirical trends found in studies of the gambler’s fallacy: they expect switches after short streaks but continuations after long ones; these nonlinear expectations vary with their familiarity with the causal system; their predictions depend on the sequence they’ve just seen; they produce sequences that are too switchy; and they exhibit greater rates of gambler’s reasoning when forming binary predictions than when forming probability estimates. In short: what’s been thought to be evidence for irrationality may instead be rational responses to limited data and memory. (shrink)

Feminist critics of evolutionary psychology are often accused of committing the naturalistic fallacy, that is, of inferring certain normative conclusions from evolutionary psychology’s purely descriptive accounts. This article refutes the accusation of the naturalistic fallacy, by showing that evolutionary psychology’s accounts of human behavior are not purely descriptive, but rather grounded on biased value judgments. A paradigmatic example is Randy Thornhill and Craig Palmer’s well-known book A Natural History of Rape. I argue that at least three biased judgments (...) are at work in Thornhill and Palmer’s evolutionary psychology account of rape: (1) adaptationist approaches to evolution, (2) willful ignorance of cultural and social context, and (3) binary understanding of gender and sex. In that Thornhill and Palmer’s account cannot hold without the three biased value judgments, it is not a purely factual description of rape. Therefore, feminist concerns over its normative implications do not commit the naturalistic fallacy, as it is not the case that they infer a normative conclusion from a pure description. (shrink)

During the last decades, the psychology of reasoning has identified experimentally many fallacies committed by spontaneous reasoners. Given these experimental results, some theories have been developed about this phenomenon, mainly algorithmic theories. This paper develops instead a computational modelling of these current fallacies which appear as simplifications in the treatment of information that do not respect the formal rules of classical propositional logic. These fallacies are explained as crushes in the Klein group structure and so, in squares of opposition. These (...) crushes are an effect of not to take into account the dual of the binary operator at work in the major premise of the inference. This analysis allows predictions on fallacies not identified before, which are fallacies produced when reasoning with incompatibilities. The paper concludes with consequences of the analysis on pedagogical strategies for the teaching of logic. (shrink)

One of the fundamental fallacies of racism is the confusion between biological accidents such as: body, colour, environment, size, shape, and melanin with metaphysical essences like; soul, mind, and intellect. Personness for instance is an essential category that does not depend on the above accidental attributes. Since time immemorial, racism has been reinforced by deeply entrenched social structures. These structures are the offspring of both overt and covert racism. Structural racism is epitomised by ideologies that have been well disguised under (...) facades of science. These ideologies include: Eugenics, Social Darwinism, Modernisation theory and Neo-liberalism. This paper critically analyses the religious, political, psychoanalytic, historical and economic construction of structural and institutional racism that reinforces honorary whiteness in the African social milieu. The paper argues that the purpose of racism is constructing Black and Brown people as entities in dire need of White Saviourism and White Paternalism. This consequently culminates into imperialism, neo-colonialism, subjugation and exploitation. The paper further contends that racism is crystalised through mental colonialism which rides on socially constructed racial binaries, dichotomies and hierarchies such as: White (righteous) and Black (evil), North (top) and South (bottom), West (Sun-rise) and (Sun-set), Aryan and Honorary Aryan, White and Honorary White.

Despite the fundamentally binary character of justification , an upsurge in recent Anglo-American scholarship offers some highly sophisticated and widely diverging conceptions of in criminal law. In the present article we identify eight distinct conceptions of partial justification. We find, however, that each of them is predicated on a different conceptual fallacy. Any sound concept of partial justification in criminal law ought to meet the dual challenge of utility and consistency: it should usefully convey a message that advances (...) the conduct-guiding function of criminal law and retain some consistency with the key attributes of complete justification, particularly its allowing function and the implications of its typically universal nature. We maintain that none of the conceptions offered to date meets this challenge. The different meanings attached to partial justification do not further the guiding function of criminal law beyond what is achieved by the scalar concept of wrongfulness; indeed, they undermine the guiding utility of criminal law by obscuring the distinction between the permissible and the impermissible, thereby also diminishing the expressivity of the criminal conviction. Furthermore, extending partial universality to the proposed notions of partial justification implausibly marks retaliating victims and intervening third parties, who react to allegedly partially justified conduct, as partly blameworthy, whereas present legal doctrine rightly affords them a full defense.

The noctes Atticae of Aulus Gellius contain almost all the ancient paradoxes. Nevertheless, in comparison with his philosophical sources, the author shows a shift in the perspective of his approach. He analyses the `master argument' of Diodorus Chronus only from an ethical point of view and, among the seven paradoxes attributed to Eubulides of Milet, he quotes the `heap' as an absurdity (absurdum), the `horned one' and the `not-someone' as a trap (captio), the `liar' as a sophism (sophisma). Following the (...) advice of Cynics, Gellius mistrusts deceptive manoeuvres, which highlight gaps in binary logic. At the same time, however, he is interested in argumentative structures, which lead one of two opponents on to victory. The extensive report of the quarrel between Protagoras and Evathlus, and many observations of Gellius on convertible forms of reasoning in literary texts fall within this rhetorical field. (shrink)

The question of whether we have free will is a longstanding philosophical debate that has led to divided fronts and interpretations. The first ambiguity arises due to a misconception about the relation between causal determinism, as formulated in classical physics, and the notion of free will, which, once clarified, undermines not only compatibilism but also naïve formulations of libertarianism. We show that either one maintains a material monistic physical causal determinism and must give up free will, or one must give (...) up determinism and embrace metaphysical ontologies. Moreover, with the advent of modern neuroscientific investigations, the questions surrounding our freedom of choice have received renewed attention but, so far, lead to several inconclusive findings. In fact, the issue is far from settled and no resolution is in sight. We contend that an exclusively third-person approach that abstracts from the deeper complexities of the human psychological nature and resists a first-person inquiry has led to a much too simplistic and superficial understanding of the problem and is affected by fallacious inferences and unwarranted conclusions. Meanwhile, an introspective approach easily reveals that our identity can't be reduced to a single personality whose choice-making is determined by a unique agency and volition. Our nature is much more complex than that. Therefore, every analysis involving propositions about free will requires more careful articulation. One cannot meaningfully answer the question of free will if it is not clear (1) what determinism is in physical sciences, (2) who is supposed to be free from what and (3) what will is. Here, we show that the question regarding free will isn't meaningful in the first place unless cleared from conceptual conflations and that it is unlikely it will ever be answered by a binary ‘yes’ or ‘no’ statement.

In lieu of an abstract, here is a brief excerpt of the content:Limit Formations:Violence, Philosophy, RhetoricOmedi Ochieng For Megha Sharma SehdevNow days are dragon-ridden, the nightmareRides upon sleep: a drunken soldieryCan leave the mother, murdered at her door,To crawl in her own blood, and go scot-free;The night can sweat with terror as beforeWe pieced our thoughts into philosophy,And planned to bring the world under a rule,Who are but weasels fighting in a hole.—W. B. Yeats, "Nineteen Hundred and Nineteen"Violence is a (...) limit formation. It is neither reducible to a brute fact nor is it ineffably ethereal. To write about violence, then, is to confront—if only as disavowed remainder—critical limits, no less of the writer than of the writing itself. Fewer subjects have proven as confounding for philosophy and rhetoric, this journal's primary charge. In both its general particulars and its specific manifolds, violence nonpluses philosophical commonplaces, upends rhetorical tropologies.Philosophy imagines itself mediator to reality's arche, the bedrock of being. Ancient Greek philosophy sought to distinguish necessity from contingency, essence from accident, dialectic from rhetoric, logic from fallacy. Those who took up this intellectual tradition came to conceptualize violence as first and foremost a question of "nature"—more specifically, those marked out by nature to rule (propertied male citizens) and those marked [End Page 330] out by nature for subjection (the enslaved, women, nonhuman animals). In the early modern context of European philosophy, still, despite its pretensions, deeply indebted to this Mediterranean legacy, the canonical lexicon of sensemaking centered on legitimacy and its conceptual appurtenances of sovereignty, will, and rights.Strikingly, it is in the opposed registers of analytic and continental philosophy that violence's cataphilosophic figuration appears most salient. Consider, for example, one such famous symposium convened in the analytic journal Philosophy and Public Affairs, as narrated by political philosopher Michael Walzer:In an earlier issue of Philosophy & Public Affairs there appeared a symposium on the rules of war which was actually (or at least more importantly) a symposium on another topic. The actual topic was whether or not a man can ever face, or ever has to face, a moral dilemma, a situation where he must choose between two courses of action both of which it would be wrong for him to undertake. Thomas Nagel worriedly suggested that this could happen and that it did happen whenever someone was forced to choose between upholding an important moral principle and avoiding some looming disaster. R. B. Brandt argued that it could not possibly happen, for there were guidelines we might follow and calculations we might go through which would necessarily yield the conclusion that one or the other course of action was the right one to undertake in the circumstances (or that it did not matter which we undertook). R. M. Hare explained how it was that someone might wrongly suppose that he was faced with a moral dilemma: sometimes, he suggested, the precepts and principles of an ordinary man, the products of his moral education, come into conflict with injunctions developed at a higher level of moral discourse. But this conflict is, or ought to be, resolved at the higher level; there is no real dilemma.(1973, 160–61)Analytic political philosophy's resolute disavowals could not be here better splayed. Morality is construed as all-encompassing. The political is not so much effaced as it is rendered derivative to a foundational drama of will, obligation, choice. Analytic philosophy's oft-preened claim to clear, transparent, terse style proves constitutive of its desire to contain, if it cannot altogether moralize away violence. [End Page 331]Where analytic philosophy conceives of violence as an object, its limits defined by morality's handmaiden, the "well-ordered society" (Rawls 2001, 8), continental philosophy conjures a sublime violence that shatters and transfigures normative violence. Walter Benjamin posits a binary opposition between mythical and divine violence: "If mythical violence is lawmaking, divine violence is law-destroying; if the former sets boundaries, the latter boundlessly destroys them; if mythical violence brings at once guilt and retribution, divine power only expiates, if the former threatens, the latter strikes, if the former is bloody, the latter is lethal without spilling...

This paper advances the concept of transversality by drawing philosophical insights from Maurice Merleau-Ponty, Calvin O. Schrag, and the Martinicuan francophone Edouard Glissant. By so doing, it attempts to deconstruct the notion of universality in modern Western philosophy. It begins with a critique of the notion of Eurocentric universality which is founded on the fallacious premise that what is particular in the West is made universal, whereas whereas what is particular in the non-West remains particular forever. Eurocentric Universality has no (...) place in the globalization of the multicultural world. It simply ignores the reality of interlacing of multiple life-worlds. The concept of transversality, whose icon is the Maitreyan Middle Way, is proposed to replace universality. It not only reduced ethnocentric particularism but also fosters a hybridity that in fact dissolves the binary opposition between particularism and universalism. In short, transversality is conceived of as a radically new paradigm in philosophical conceptualization or world philosophy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Why Narcissists Are Morally ResponsibleAleksandar Fatic, PhDIn his insightful commentary of ‘Narcissism as a moral incompetence,’ Professor Pies proposes several principal objections to my line of argument. First, Pies mentions that I embrace a Platonic essentialism and a ‘binary’ view of narcissism, whilst in fact narcissistic traits present themselves in degrees, within a continuum of pathology.Let us clarify the meaning of essentialism. When applied to the phenomenology of (...) narcissism, Platonic essentialism would imply that there is an idea, or ideal, of ‘pure’ narcissism, which governs our cognition of narcissistic phenomenology. Without an ‘essentialist’ understanding of what narcissism as a more or less pure phenomenon would look like, it would make no semantic or logical sense to speak of various ‘types’ or ‘degrees’ of narcissism. In the 1940s, in The Concept of Mind, Gilbert Ryle offered the now infamous logical analysis of ‘false’ and ‘true coins’: if there were not true coins of which we had some idea, it would be logically impossible to speak of counterfeit coins (McDermid, 2004; Ryle, 1949, pp. 94–99). There are shoddily produced coins that bear only a vague resemblance to the original idea or mint of the real coin, however, for each we would ultimately have to decide whether the resemblance is sufficient for it to be considered a real coin. Shoddily produced coins represent various ‘degrees’ of resemblance of the idea, or form, of a coin, but to call them coins, and to decide whether they are true coins or not, it is a logical presupposition that we must first have an ‘idea’ of what an ‘ideal’ real coin is like. This, at its core, is essentialism.There is no escape from this type of essentialism in any rigorous argument, because Platonic essentialism is the foundation of the very meanings of the concepts we use. Plato’s ideas are paradigms, where the particular instantiations of their qualities are called ‘phenomena’ (Sedley, 2016; Taylor, 2016). Thus, the nuanced expression of ideas or forms in their various phenomena is the very substance of the essentialist theory of ideas. It appears that Professor Pies is also a Platonic essentialist, as am I.So why is it often impossible in clinical practice to ascribe necessary and sufficient conditions to narcissism? Well, let us remember Rosenhan’s experiments (1973). Rosenhan illustrates how the same individuals were diagnosed with very different disorders by different clinicians at roughly the same time, and how healthy individuals, once they had been instructed to ‘fake’ psychotic symptoms, remained under the same or more serious [End Page 177] diagnoses even when they stopped pretending and behaved completely normally. The reason for the arbitrariness of psych-diagnoses is the insufficiency of the psych-diagnostic language, including the actual diagnostic criteria, a kind of Lacanian ‘lack’ that is built into the very structure of psychodiagnostics (Ruti, 2008), and not a metaphysics behind such use of diagnostic language, whether it is essentialist or non-essentialist. Whether a particular patient actually has NPD or not in practice comes down to a consensual judgement—one that has been notoriously lacking in the history of psychiatry (Verhaeghe, 2008, pp. 71–125).Second, Pies suggests that empathy is ‘a complex, multidimensional construct comprising cognitive and affective components.’ I do not think this is a correct understanding of empathy. In fact, it is a conceptual revision of the original concept of empathy, which is one of a moral emotion (Kauppinen, 2014). What Pies calls ‘cognitive empathy,’ namely the ability to recognize and influence the emotions of others is an entirely different quality capacity that has recently been called ‘emotional intelligence’ (e.g., Conte, 2005). Many Cluster B personality disorders are characterized by an exceptionally high emotional intelligence and an almost complete lack of empathy, which allows them to use their emotional intelligence to manipulate and mistreat others. Surely such emotionally intelligent, but highly malignant strategies would not be considered ‘empathy.”Relatedly, Pies objects to Slote’s alleged view that only actions arising from factual empathy are morally justifiable. This is a ‘naturalist fallacy’ in reading Slote. The natural fallacy is a confusion between the ‘is’ and the ‘ought.’ Slote actually argues that only actions that are consistent with... (shrink)

While many film theorists declare Agamben as, in equal part, a Deleuzian film theorist, I pose that, through this Benjaminian lens, we can parse distinctive cinematic questions that Agamben exclusively pursues - in particular, cinema's potential as a repurposive counter-dispositif to combat dominant forms via critique. This is not to suggest that parallels do not exist between Agamben and Deleuze’s approaches: as Meillassoux has noted, Deleuze's logic of representation (also known as "correlationism") develops an "image of thought that attempts to (...) overcome the binary separation” between matter and spirit, mind and body. Furthermore, Agamben is unequivocally astricted to the Bergson-bound Deleuzian tradition of "untimeliness," whereby cinema extricates "the fallacious psychological distinction between image as psychic reality and movement as physical reality." Furthermore, both Agamben and Deleuze are committed to a notion of "cinema-thought," as Jean-Luc Nancy terms it, or haecceities of Oneness—a commitment to cinema-as-immanence, or indexing thought, rather than mediating it via hermetic historicism. However, Agamben's concept of gesture, as a prelinguistic mode of communication, suspends the symbolic, replacing taxonomy and, therefore, offers a sublime breach: "Gesture is the communication of a potential to be communicated." In other words, Agamben’s gesture is something of an “enigmatic signifier,” insofar as it is impregnated with a primitive and unconscious meaning. (shrink)

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.

We want to know what gender is. But metaphysical approaches to this question solely have focused on the binary gender kinds men and women. By overlooking those who identify outside of the binary–the group I call ‘genderqueer’–we are left without tools for understanding these new and quickly growing gender identifications. This metaphysical gap in turn creates a conceptual lacuna that contributes to systematic misunderstanding of genderqueer persons. In this paper, I argue that to better understand genderqueer identities, we (...) must recognize a new type of gender kind: critical gender kinds, or kinds whose members collectively destabilize one or more pieces of dominant gender ideology. After developing a model of critical gender kinds, I suggest that genderqueer is best modeled as a critical gender kind that destabilizes the ‘binary axis’, or the piece of dominant gender ideology that says that the only possible genders are the binary, discrete, exclusive, and exhaustive kinds men and women.

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)

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)

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)

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)

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)

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 author suggests, however tentatively, that in the challenge of heterogeneity, fractality, perspective/-alism, and multiplicities lies the power of the forking pathway: the moment a relation is created through divergence. If we are invited—in the same breath—to consider forms of comparison and forms of relativism (dropping difference and similarity), we are also offered two (...) paths, one based on a world of singularities and multiplicities, and the other on a world of not-quite repetitions. The article asks if the binary is not essential to the epistemic work that Western (Euro-American) scholars might want to do, since we forever reinvent the divide between the modern and the post-/pre-modern. Strathern assumes the anthropologist's license to talk about concepts through persons, and begins by asking how Papua New Guineans who come together in a city compare themselves, and in contrast to ethnic comparisons elsewhere (e.g., contra Sarah Green's Balkan interactions). In talking about persons through concepts, it is worth asking what is entailed in relativizing one scholar's work through that of another. The author says that her “hunch” is that in both cases the analyst might wish to have the liberty of discerning—in the same breath—the multiplicities of what John Law and Annemarie Mol call perspectivalism (their very general alternative to comparison) and Eduardo Viveiros de Castro's radically divergent perspectivism (a self-contained, recursive and above all socially specific relativism).

I will situate the fallacies approach to reasoning with the aim of making it more relevant to contemporary life and thus intellectually significant and valuable as a method for teaching reasoning. This entails a revision that will relegate some of the traditional fallacies to the realm of history and introduce more recently recognized problems in reasoning. Some newly recognized problems that demand attention are revealed by contemporary science studies, which reveal at least two tenacious problems in reasoning that I will (...) explore in this paper. One of these problems is androcentrism, a ubiquitous problem with reasoning that feminists exposed in the twentieth century but that continues to pervade people’s reasoning. The other is biological reductionism in at least two specific forms: genetic determinism and adaptationism. (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.

This paper presents a way of formalising definite descriptions with a binary quantifier ι, where ιx[F, G] is read as ‘The F is G’. Introduction and elimination rules for ι in a system of intuitionist negative free logic are formulated. Procedures for removing maximal formulas of the form ιx[F, G] are given, and it is shown that deductions in the system can be brought into normal form.

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)

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.

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)

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 Yijing/Binary System Episode involved Leibniz' discovery of a de facto representation of the binary number system in the sixty-four-hexagram Fu Xi "Yijing." Scholars have left the match unexplained, since they have found no evidence of a forgotten binary number system in ancient China. The interesting similarities and differences are discussed between the thought of Leibniz and that of Shao Yong, both of whom, it is argued, understood and recognized the importance of the double geometric progression in (...) the diagram.

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)

Philosophical and ethical discussions of warfare are often tied to emerging technologies and techniques. Today we are presented with what many believe is a radical shift in the nature of war-the realization of conflict in the cyber-realm, the so-called.

Black-white, male-female — these and other markers, applied maliciously or not, enable the social dominance of one group.
