Previous commentators on Plato’s Republic have relied on mistaken assumptions about the requirements for Plato’s theory of justice: that Plato establishes a bi-conditional between proper psychic rule and the performance of conventionally just acts. They believe that if Plato does not establish this bi-conditional, then his theory of justice as a virtue will succumb to the fallacy of irrelevance. I claim Plato need not meet that requirement. A novel interpretation of the arguments of Book IV concerning justice in the (...) soul suffices to dispense with one aspect of the bi-conditional – that conventional justice must imply justice as psychic harmony. Then, situating the theory of justice as psychic harmony in the context of the divided line, and in the dialectical ascent in the education of the philosopher-rulers, I show that the other conditional requirement – that justice in the soul must imply the performance of conventionally just actions – is also mistaken.

The fallacies approach to argument evaluation can exacerbate problems it aims to address when it comes to social bias, perpetuating social injustice. A diagnosis that an argument commits a fallacy may flag the irrelevance of stereotypical characterizations to the line of reasoning without directly challenging the stereotypes. This becomes most apparent when personal bias is part of the subject matter under discussion, in ethotic argument, including ad hominem and ad verecundiam, which may be recognized as fallacious without addressing (...) whether the ethotic presumptions are true. Yap (2013; 2015) makes this case for ad hominem and the pragma-dialectical understanding of fallacies, expanded here to show related patterns in some other fallacies, and employing the argument schemes understanding of fallacies. Adding critical questions increases the ways reasoners can dismiss arguments as fallacious, and could include directly addressing bias, but if an argument fails on a different critical question, that may yet allow the bias to pass. The fallacies approach is a form of meta-debate and techniques of meta-debate need to address the ubiquity of social bias, not convey them as specialized problems. The view that the fallacies approach to argument evaluation can provide neutrality is dangerously false. Arguers thus should avoid using fallacies for argument evaluation where social stereotypes or schemas might be involved, especially when the subject matter relates closely to social justice.

In this paper I demonstrate that most textbook accounts of the linked/convergent distinction fail to conform to the widespread intuition that all valid arguments ought to be classified as linked arguments. I also show that standard textbook accounts of linkage and convergence cannot provide a satisfactory treatment of fallacies of irrelevance and, due to their general insensitivity to the epistemic context in which arguments are offered, must be supplemented by subjective accounts of linkage and convergence which appeal exclusively (...) to authorial beliefs and intentions.

This chapter focuses on one of the common fallacies in Western philosophy called 'irrelevant conclusion'. The fallacy of irrelevant conclusion, also known as the ignoratio elenchi (“ignorance of the proof”) fallacy, is, in effect, the parent of all other fallacies since every fallacy yields a conclusion that even if it be true is not related – that is, is irrelevant – to the premises of the argument. Arguments that commit the irrelevant conclusion fallacy all end with a conclusion (...) that is not related in any necessary way to the premises. Avoiding this fallacy is easier said than done, for it requires one to be a critical thinker at all times. The chapter finally presents an example of an argument with an irrelevant conclusion.

History of science and philosophy of science are not logically related: to claim that they are would be either to underestimate or to misunderstand the genetic fallacy. But one risk of inferring that there is no connection at all between the two is the risk that philosophers of science may not know what they are talking about. The philosopher of science who does not know intimately the history of the scientific problem with which he is exercised may be discussing no (...) genuine state of affairs. On the other hand, The historian and philosopher of science are both concerned with the structure of scientific ideas, And these concerns are fused into one when the scientific "argumentation" of the past is the issue.

In a series of important papers, Justin D’Arms and Daniel Jacobson argue that all extant neo-sentimentalists are guilty of a conflation error that they call the moralistic fallacy. One commits the moralistic fallacy when one infers from the fact that it would be morally wrong to experience an affective attitude—e.g., it would be wrong to be amused—that the attitude does not fit its object—e.g., that it is not funny. Such inferences, they argue, conflate the appropriateness conditions of attitudinal responses with (...) the fittingness conditions of the associated evaluative properties. Further, they argue that moral considerations are irrelevant for determining if amusement fits its object. We agree that a strong moralizing of humor is wrongheaded and that jokes can be quite funny even in cases where we have a compelling moral reason to not be amused. However, we argue that pace D’Arms and Jacobson moral considerations can be relevant for property ascription. On our view, in order for a joke to be funny, a properly sensitive agent must take herself to have a contributory reason to be amused, and in some cases that she lacks such a reason is best explained by appeal to moral considerations. We use this constraint as the basis of what we call our modest proposal for a modest sentimentalism. (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.

Nietzsche’s late writings present a value opposition of health and decadence based in his conception of organic life. While this appears to be a moral ideal that risks the naturalistic fallacy of directly deriving norms from facts, it instead describes a meta-ethical ideal: the necessary conditions for any kind of moral agency. Nietzsche’s ideal of health not only evades but also dissolves the naturalistic fallacy by suggesting that the specific content of morality is irrelevant. If health is measured by power (...) over one’s drives rather than the environment, then the source of moral conflict—organic life’s essential tendency toward domination—is surmounted by successful integration of any moral norms, regardless of content. Nietzsche’s concept of health draws on his characterization of organic life as essentially ‘exploitation’: growth through domination of the environment (BGE 259, GM II: 12). In animals, power coincides with happiness, while health and decadence track the correspondence between instinct and happiness (TI II: 11). This simple picture is complicated by the Genealogy, where Nietzsche depicts human nature as an animal illness caused by civilization’s disruption of the natural correspondence of instinct and happiness. Civilization shapes this ‘sick animal’ into the distinctly human ‘sovereign individual’ (GM III: 13, II: 2), restoring the harmony of instinct and happiness in an internal hierarchy of drives. So, sovereign individuality is a distinctly human model of health. Although life is exploitation, human health does not coincide with greater environmental power, but rather an internal qualitative expansion of power: greater variety and tension among drives, greater ‘wholeness in diversity’ in the ‘social structure’ of the self (BGE 212, 12). Nonetheless, health is not a moral criterion, but instead the precondition of moral agency. The subordination of drives to a commanding hierarchy grounds the ability to uphold any moral principles at all, to make and keep promises to oneself and others. Moral agency coincides, in turn, with overcoming the source of moral conflict in organic life’s drive for growth. The unification of opposing drives provides pleasure in power over oneself rather than one’s environment, the ‘happiness of high tension’ among drives (BGE 260), and in environmental resistance, a need for ‘equal opponents’ (TI IX: 38, EH 1: 7). Consequently, Nietzsche’s meta-ethical ideal supports a moral pluralism that supports any moral content. Moral conflicts arise precisely to the degree individuals are incapable of achieving moral agency, but they dissolve as moral agency of any kind is more widely achieved. (shrink)

This paper uses argument diagrams, argumentation schemes, and some tools from formal argumentation systems developed in artificial intelligence to build a graph-theoretic model of relevance shown to be applicable as a practical method for helping a third party judge issues of relevance or irrelevance of an argument in real examples. Examples used to illustrate how the method works are drawn from disputes about relevance in natural language discourse, including a criminal trial and a parliamentary debate.

An ad hominem fallacy is committed when an individual employs an irrelevant personal attack against an opponent instead of addressing that opponent’s argument. Many discussions of such fallacies discuss judgments of relevance about such personal attacks, and consider how we might distinguish those that are relevant from those that are not. This paper will argue that the literature on bias and testimony can helpfully contribute to that analysis. This will highlight ways in which biases, particularly unconscious biases, can make (...) ad hominem fallacies seem effective, even when the irrelevance is recognized. (shrink)

Plato’s account of justice in the Republic has been questioned by David Sachs, who charges Plato for committing a fallacy of irrelevance. Sachs’ objection is built on the assumption that Plato has employed two accounts of justice: a vulgar one, and a Platonic one. Insofar as Socrates’ interlocutors hold a vulgar conception, then Socrates should prove to them that being vulgarly just will be beneficial to them. But Socrates, according to Sachs, never does that. Through emphasizing the dialogues of (...) Socrates with his interlocutors, this essay shows incorrect the assumption that Plato is holding two accounts of justice. The dialogues in the Republic demonstrate that there are vulgar confusions, rather than a vulgar ideology. Furthermore, through defining justice as the dominance of reason over humans and politics, and through relating reason to the Good, Plato leaves open the possibility that some vulgar actions conform to his account of justice.

In a brief but remarkable section of the Inquiry into the Human Mind, Thomas Reid argued that the visual field is governed by principles other than the familiar theorems of Euclid—theorems we would nowadays classify as Riemannian. On the strength of this section, he has been credited by Norman Daniels, R. B. Angell, and others with discovering non-Euclidean geometry over half a century before the mathematicians—sixty years before Lobachevsky and ninety years before Riemann. I believe that Reid does indeed have (...) a fair claim to have discovered a non-Euclidean geometry. However, the real basis of Reid’s geometry of visibles is subtle and easy to misidentify. My main aim in what follows is to make clear what the real basis is, separating it from several fallacious or irrelevant considerations on which Reid may seem to be relying. A secondary aim is to air the worry that Reid’s case for his geometry can succeed only at the cost of compromising the achievement for which Reid is best known—his direct realist theory of perception.

Neuroeconomic studies are liable to fall into the reverse inference fallacy, a form of affirmation of the consequent. More generally neuroeconomics relies on two problematic steps, namely the inference from brain activities to the engagement of cognitive processes in experimental tasks, and the presupposition that such inferred cognitive processes are relevant to economic theorizing. The first step only constitutes the reverse inference fallacy proper and ways to correct it include a better sense of the neural response selectivity of the targeted (...) brain areas and a better definition of relevant cognitive ontologies for neuroeconomics. This second way also allows increased coherence between the cognitive processes actually involved in neuroeconomics experiments and the theoretical constructs of economics. We suggest means of increasing neural response selectivity in neuroeconomic experimental paradigms. We also discuss how the choice of cognitive ontologies can both avoid implicit reductionist strategies (from economic constructs to neural patterns) and irrelevance, as cognitive processes engaged in experimental tasks may lack immediate bearing on the study of economic behavior. With these joint improvements neuroeconomics can be a progressive science. (shrink)

How to model relevance in argumentation is an important problem for informal logic. Dialectical relcvance is determined by the use of an argument for some purpose in different types of dialogue, according to the ncw dialectic. A central type of dialogue is persuasion dialogue in which one participant uses rational argumentation to try to get the other participant to accept a designated proposition. In this paper, a method for judging relevance in persuasion dialogue is presented. The method is based on (...) using the technique of argument diagramming. (shrink)

The validity of argument by disjunctive syllogism has been denied by proponents of relevant and paraconsistent logic. DS is stigmatised for its role in inferences — most notably C.I. Lewis's derivation of that fallacy of irrelevance ex falso quodlibet — that involve both it and other rules of inference governing disjunction, or, to speak more precisely, other rules of inference taken to apply to the very same disjunction that obeys DS. In avoiding these inferences the road less travelled is (...) to deny the identity rather than to deny DS: what follows is, then, an exercise in disjoining disjunctions. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy called 'proximate causation'. One commits this variety of causal fallacy when one mistakes the relevance of proximate causation. One mistakes the relevance of proximate causation when one thinks the fact that something is a proximate cause makes it irrelevant to the story of how the event in question happened. Mistaking the relevance of proximate causation can also “go the other way”. That is, one can overinflate the importance (...) of something being a proximate cause. This is often done by those looking to avoid responsibility for their actions. Matters of causation are never simple. And sometimes whether something is a proximate cause is relevant to the issue at hand. But we must be careful to make sure that we do not mistake its relevance. (shrink)

Professor Garver’s “Living Well and Living Together” sheds light on one of the more confusing sections in Aristotle’s Politics, namely the discussion of the best way of life for individuals and city in Politics VII.1-3. At a distance, the conclusion of Aristotle’s remarks seem relatively clear: He endorses the claim that the most choice-worthy life and happiness of a city and an individual are the same. Further, the implications of such a claim for Aristotle’s political philosophy also seem clear: Aristotle’s (...) view of an “internally active” city amounts to a thorough critique of expansionist imperialism. But how these two surface level views—the best way of life for a city and the critique of imperialism—fit together is less than perspicuous. Garver’s paper goes after this text through the lens of two problems. First, Aristotle apparently argues from the nature of the best way of life or happiness for an individual to the best way of life for a city. But as Aristotle himself points out in his critique of the Republic, such an argument seems in danger of falling into a fallacy of composition. In response to such a perceived fallacy, Garver argues that Aristotle incorporates into his argument a third thing—what is the best life for a citizen or what Garver calls “common life” (p. 5, 6, of Garver’s text)—which mediates between the best life for a separate individual and for the city. As Garver puts it at one point “the best life for the citizen will be our means for discovering those [other] two” (p. 5, Garver’s text). The second problem which Garver raises concerns Aristotle’s apparent inference from energeiai to dunameis. Aristotle’s argument in Politics VII.1-3 begins from the claim that a city and individual have the same kind of happiness—namely, a sort of energeia—and extends to a claim about the structure which serves as the basis of that activity. The problem, according to Garver, is that “the virtues of the state cannot be energeiai of that part of its soul, because states don’t have souls” (p. 6, Garver’s text). The comparison between city and individual works—if it does work—only if “the psychological aspects of the virtue central to the Ethics become politically irrelevant” (p. 7, Garver’s text). Thus, Garver suggests that Aristotle’s comparison of city and individual comes at a cost, viz. that “Aristotle can talk about states being virtuous and happy only because of this psychological superficiality” (p. 9, Garver’s text).

The Church–Turing Thesis (CTT) is often employed in arguments for computationalism. I scrutinize the most prominent of such arguments in light of recent work on CTT and argue that they are unsound. Although CTT does nothing to support computationalism, it is not irrelevant to it. By eliminating misunderstandings about the relationship between CTT and computationalism, we deepen our appreciation of computationalism as an empirical hypothesis.

Usually, we read news to form opinions and expand our knowledge. However, especially in the past years, more and more publications are moving apart from being objective. Therefore, we get biased knowledge. In this article, we aim to observe the way information is passed from a logical and rhetorical point of view in different publications. By this, we do not aim to evaluate the morality of the publications or journalists in questions, our aim is purely theoretical (i.e. logical and rhetorical). (...) In order to be able to provide such an analysis, we picked different pieces of news with the same topic from various publications. The chosen topic is irrelevant to the theoretical content, therefore we do not aim to focus on its political or social implications. The decision was made in order to have sufficient material to provide a proper theoretical analysis. It should also be added that any evaluative terms that are going to be used in this article (e.g. ‘biased’, ‘subjective’, ‘not objective’, ‘one-sided’, etc.) are strictly directed to a theoretical perspective, not a moral, social or political one. As already mentioned, our aim is as theoretical as possible: we are interested in the logical and rhetorical structure of a piece of information. (shrink)

Contrary to dictionaries, a non sequitur isn’t “any statement that doesn’t follow logically from previous statements”. Otherwise, every opening statement would be a non sequitur: a non sequitur is a statement claimed to follow from previous statements but that doesn’t follow. If the sentence making a given statement doesn’t contain ‘thus’, ‘so’, ‘hence’, ‘therefore’, or something else indicating an implication claim, the statement isn’t a non sequitur in this sense. But this is only one of several senses of that expression, (...) which, contrary to appearances, is a unitary common noun more properly written as one word: non-sequitur or nonsequitur. Above a nonsequitur was, roughly speaking, a conclusion of an invalid premise- conclusion argument, but not every such, only those that were stated to follow from premises that had been stated. Every informative proposition is the conclusion of an invalid argument. Anyway, nonsequiturs were not arguments. However, the expression ‘nonsequitur’ also means “invalid premise- conclusion argument”. It also means something like “fallacious reasoning” as in ‘Abe’s proof of the big-bang hypothesis is a nonsequitur’. The English noun is also used for an irrelevancy, an abrupt change of topic, or for any of many other expressions that are gratuitous, inappropriate, incongruous, or in some other way out of place. The English noun is derived from the Latin expression ‘non sequitur’, which is not a common noun but a sentence variously meaning “it isn’t in sequence ”, “it doesn’t follow”, “it is out of order”, etc. A statement that begins ‘in the second place’ is a nonsequitur if the previous sentence lacked implication of something like ‘in the first place’ or if it contained something similar to ‘in the third place’. In fact, a true implication claim can be a nonsequitur if there is no reason for making it. If Ben says ‘Hence, Abe swims and Abe swims’ in reply to Carl’s statement ‘Abe swims‘, then Ben may well be committing a nonsequitur. Many conversation stoppers are nonsequiturs. This lecture surveys and analyses a wide selection of uses of ‘nonsequitur’ in logic and logic-related literature. -/- END OF DRAFT 4 -/- NOTE 091215: When Rick Perry was discussing possible withdrawal from the race—unfortunately not the human race but the Republican race—a reporter reminded him that just last week Donald Trump predicted the Perry withdrawal.

This paper aims to establish several interconnected points. First, a particular interpretation of the mathematical definition of information, known as the causal interpretation, is supported largely by misunderstandings of the engineering context from which it was taken. A better interpretation, which makes the definition and quantification of information relative to the function of its user, is outlined. The first half of the paper is given over to introducing communication theory and its competing interpretations. The second half explores three consequences of (...) the main thesis. First, a popular claim that the quantification of information in a signal is irrelevant for the meaning of that signal is exposed as fallacious. Second, a popular distinction between causal and semantic information is shown to be misleading, and I argue it should be replaced with a related distinction between natural and intentional signs. Finally, I argue that recent empirical work from microbiology and cognitive science drawing on resources of mathematical communication theory is best interpreted by the functional account. Overall, a functional approach is shown to be both theoretically and empirically well-supported. (shrink)

This book addresses the topic of the explicit and implicit commitments about persons as a kind in the literature on personal identity and draws out their political implications. I claim that the political implications of a metaphysical account can serve as a test on its veracity in cases in which the object-kind under analysis is itself constitutively normative, as the kind person might be, or in those cases in which counting as a member of the kind in question confers a (...) certain normative status upon those that do so count, which the kind person certainly satisfies. I argue that metaphysical accounts of personal identity often contain certain mistaken background assumptions concerning personhood, often due to a failure to recognize that being a person is environmentally dependent. -/- Because being a person is environmentally dependent, but this is not often noted, let alone incorporated into our theories of persons, although there are exceptions, a closer look at those theories is required if we are to have a just society. In fact, it is a bit surprising that this is the current situation, since the claim that certain members of society are oppressed due to being denied full personhood and its attendant rights has been the basis of several social movements: first-wave feminism, anti-slavery movements, and civil rights movements generally. Historically, these resistance movements aimed at claiming that, unlike how they were treated, they did in fact meet the requirements for personhood that those in more privileged sectors did and should therefore enjoy the same rights as the more privileged. -/- While I agree with the justification for these movements -- that the injustice driving them is that of the denial of the rights of persons -- I advocate for moving away from the idea that the only appropriate response is to count those who make such claims as being members that meet the dominant conception of personhood. Instead, I want to highlight the fact that if being a person is an environmentally dependent fact, theories of the nature of persons must recognize this or risk reflecting and perpetuating the current status quo. -/- For these reasons, those in need of recognition of their rights as persons should not only resist the failure of having them granted but should also question the current understanding of the concept itself, since the very notion may be riddled with normative assumptions typical only of those with certain kinds of privilege. That is, fighting for recognition as persons, without also resisting and questioning the source and objectivity of our current concept of personhood, risks failing to truly challenge the currently unfair social structure in any deep way. -/- There is a risk, however, with taking such a stance -- that it will be fallaciously inferred that there is no fair concept of persons at all to which are owed rights. But this does not follow from the stance I take. All that follows is that we must recognize our fallibility in offering metaphysical theories, particularly when the concept under investigation is normatively sensitive and environmentally dependent in the way that the kind person seems to be. -/- Theories concerning the metaphysics of persons, then, must address the fact that those with privilege not only have more power to assert their rights as persons, but they are also the source of most received views of the concept itself. It is possible, therefore, that our current metaphysical theories may be mis-describing the objective nature of personhood as a kind for politically biased reasons. -/- I argue that one of the particularly pernicious assumptions frequently made is that to be a person is to be a certain kind of psychologically integrated being. This is an ideal we seem to hold dear, since we tend to pathologize the failure to achieve it. I claim, however, that this thesis about persons as integrated is exactly the kind of idea that fails the environmental dependence test, since this state of integration is often only readily had by those who have a certain amount of control over their external environment, which many of us do not enjoy. For those who are not members of the dominant group, a strongly integrated self is sometimes simply not on the horizon, since being subject to the vicissitudes of the external environment often leads to conflict, fragmentation, or disintegration. Having inadequate power over one's own circumstances tends to produce what we might call “fractured selves,” selves that face a multitude of environmental forces, many times thrusting contradictory norms, roles, and traits, upon those subjected to them. -/- The fact that the failure to achieve integration is in fact pathologized makes the integration thesis seriously questionable, since it creates a situation in which those most in need of being conferred the normative status of being a person will fail to get such recognition, and in fact, possibly labelled as "defective" in some way or other. This is unjust for many reasons, at least one of which is that it relies on morally irrelevant facts to determine a person's normative status. -/- The previous issues raise the question of whether the aim of a giving a metaphysical account of persons ought to be understood descriptively or prescriptively, since current metaphysical accounts would fail to count many individuals as persons. However, taking metaphysical accounts as a prescriptive is highly controversial. I doubt that most of those offering explicit metaphysical theories of persons would agree that they are engaged in any kind of prescriptive project. Some psychologists and psychiatrists perhaps may take themselves to be determining whether a person is "healthy" by our current understanding of what it is to be a person, but the idea of having a healthy psychology sufficient for being a fully competent person is vastly different from having a healthy physical body, which does seem to have a more objective basis, although even this is questioned in disability studies. -/- The strong integration thesis, then, as now applied, clearly raises political issues, and has potential negative consequences for many beings that we typically do think of as persons. The integration thesis then needs to be replaced with a more adequately descriptive metaphysical theory or revised in a way so that it avoids these negative political consequences. -/- I see two paths open: (1) maintain the integration thesis as an ideal, and grant those who fail to meet it a temporary kind of normative status equal to that of being a person and push for substantive equal opportunity to achieve integration; or (2) reject the ideal altogether and offer a different account of the nature of being a person that counts so-called "fractured selves" as persons. -/- I believe that path (2) is preferable to path (1) for several reasons. First, it requires no condescension or paternalistic attitudes towards those who fail to be fully integrated; second, it expresses intellectual humility in accepting that standards that appear objective are often, in reality, biased and should not be universally applied; and third, it is more realistic in that it does not assume that there is an infinite amount of resources, and therefore harbors no illusions that equalizing power structures will allow everyone to enjoy the same amount and kind of power currently held by the dominant classes. -/- My own metaphysical account of what matters for survival to persons over time advocates for the idea that persons ought to be understood as constituted not only by internal psychological relations, but also by their relations to their surrounding environments, and this includes relations to inanimate objects. This view, I argue, can accommodate fractured selves as full persons, allowing for various psychological configurations to count as persons. It is also an improvement on views that do happen to recognize the environmental influence on persons -- social constitution views. The reason is that these views argue that persons just are what their environmental social surroundings dictate, which also has potentially negative political consequences, since it threatens to bind persons so closely to socio-cultural contexts that it closes off the possibility of resistance to them. However, because the view I endorse, makes persons environmentally dependent not only on their socio-cultural context, but on the whole of their environment, this makes persons partly independent of socio-cultural contexts, allowing them room to question them, which as noted, I believe they should be.

Relevance is a triadic relation between an item, an outcome or goal, and a situation. Causal relevance consists in an item's ability to help produce an outcome in a situation. Epistemic relevance, a distinct concept, consists in the ability of a piece of information (or a speech act communicating or requesting a piece of information) to help achieve an epistemic goal in a situation. It has this ability when it can be ineliminably combined with other at least potentially accurate information (...) to achieve the goal. The relevance of a conversational contribution, premiss relevance and conclusion relevance are species of epistemic relevance thus defined. The conception of premiss relevance which results provides a basis for determining when the various ‘arguments ad’ called fallacies of relevance are indeed irrelevant. In particular, an ad verecundiam appeal is irrelevant if the authority cited lacks expertise in a cognitive domain to which the conclusion belongs, the authority does not exercise its expertise in coming to endorse the conclusion, or the conclusion does not belong to a cognitive domain; otherwise the ad verecundiam is relevant.

It has been claimed that the recent wave of neuroscientific research into the physiological underpinnings of our moral intuitions has normative implications. In particular, it has been claimed that this research discredits our deontological intuitions about cases, without discrediting our consequentialist intuitions about cases. In this paper I demur. I argue that such attempts to extract normative conclusions from neuroscientific research face a fundamental dilemma: either they focus on the emotional or evolved nature of the psychological processes underlying deontological intuitions, (...) in which case the arguments rely on a blatantly fallacious inference, or they appeal to the (alleged) moral irrelevance of the factors to which deontological intuitions respond, in which case the neuroscientific results end up playing no role in the overall argument.

Nor is the life you're left with after your boyfriend has left you for another woman - at least, that's how it felt in October last year when mine broke rank and went off with an art student from Cleveland, Ohio. We were over there for the opening of his new art exhibition. He'd flown over four days before me and had met her at a party. Supposedly, they "connected". The five months that followed were a roller-coaster of confusion, vitriol and despair. I knew there'd been problems in our relationship. We saw the world very differently; he delighted in the charm of the ordinary, I wanted maximum divinity. He walked; I galloped. He drank tea; I loathed the stuff. But, along the banks of the Thames, we'd made a promise to always stick together. Our love was something unique: "transcendental", I called it. And besides, we recycled. Surely a commitment to save the world would save our relationship? Alas, no. So there I was, a woman scorned. Hell truly hath no greater fury. And what made it worse was that I still believed in our transcendental love. If I wanted to change the way I was feeling, I needed to alter the way I was thinking. But how? A few bottles of wine and a sharp blow to the head might have done the trick. Fortunately, there's an older, more trusted way of turning your head on its head that counsellors are starting to use: philosophy. The idea of employing Plato as an agony aunt was begun in 1981 by the German philosopher Gerd Achenbach. Although philosophy spends a lot of its time asking real-life questions that affect real-life people - What is happiness? And is it always wrong to lie? - most of the debate goes on in ivory towers. What Achenbach and subsequent philosophers including Tim LeBon, the chairman of the UK's Society for Philosophy in Practice, wanted to do was "give practical application" to this gigantic library of great thoughts. So how does it work? Like most types of therapy, you sign up for a set of sessions. "Two would give you a new perspective on one issue; six would help you to make a major life-decision, like a career change; with 12 you can start to rethink your entire life philosophy," explains LeBon. Each session lasts 50 minutes and costs £50 - and, no, you don't have to have any previous knowledge of philosophy. "If you think of Friends, it would suit Ross and Chandler more than Joey," LeBon says. "It's for anyone who wants to make their emotions more intelligent. Or for those who have tried other kinds of therapy, and want something more cerebral." The first session begins with the patient venting off about whatever's troubling them. The rant over, the counsellor then picks out some key concepts that are crucial to the problem - in the case of heartbreak, it is love and happiness that come hurtling to the fore - and then gets the patient to define what they mean. So, what is love? What is happiness? To kick-start the patient's thinking, LeBon describes what a great philosopher had to say about it. In my case, he tells me what Plato wrote about love in his Symposium: that to stop man fighting the gods, Zeus decided to cut each human in two, so they would lose their strength. "This, then, is the source of our desire to love each other," Plato said. "Each of us is a 'matching half' of a human whole, because each was sliced like a flatfish, two out of one, and each of us is always seeking the half that matches him." This method of probing what we might think are "obvious" ideas, such as love and happiness, was devised by Socrates in the squares of Athens. "The only I thing I know is that I know nothing at all," he boasted. What Socrates showed was that although many of the thinkers of his time thought they knew what justice, happiness and goodness meant, their understanding was tied in to their personal agenda and world view, and, what's more, when pushed, their ideas often contradicted themselves. A bit like me on love. Whereas part of my understanding of love was something that gave life meaning, made it worth living and bound us together, I also believed that true love was "transcendental": that it was out of this world, and it didn't matter if the two people who loved each other couldn't get along in the day-to-day. Love was bigger than the mundane. But when it came to the next stage of the therapy, critical thinking - "to check out whether your assumptions stand up to examination" - I walked head first into a contradiction. If I think love's purpose is to make life worth living, but then say it's irrelevant to daily life, surely my two ideas of love are not compatible? As the cogs in my brain start to creak into motion, I feel myself taking a step back from my predicament: thinking about how I've been thinking. This idea I had of transcendental love might have started off as a romantic dream. But when the relationship stopped working, and I found myself feeling trapped and frustrated, I used it to justify the mechanics of a relationship that just didn't work in the daily grind. I used it to lie to myself. In the final stage, LeBon gets me to start thinking about how to go forward. "You can't change what has happened," he says. "You can't change that he's left you, or how you behaved in the relationship. So, as the Stoics did, let's work on controlling the controllables: the things that you can change." To work out what can be changed, he gets me to try out a thought experiment, a method often used in philosophy to imagine other worlds where people can have different codes of behaviour. Thought experiments shatter your preconceived ideas of how the world should be and let your imagination run wild to how the world could be. "I find Viktor Frankl very useful here, the Austrian psychiatrist and concentration-camp survivor who actually believed that everything in life happens for a purpose," LeBon says. "Suppose this break-up did happen for a reason that will work to your benefit," he suggests. "What might that be? The answer might be that you can now focus on something important that was denied in the relationship. Or - the Hollywood version - so you'll meet someone who is really right for you." Temporarily freed of any sense of responsibility for the relationship that was, and its sorry demise, the list came fast. I could now travel more; he didn't like me travelling on my own, but too often he didn't want to go anywhere, preferring to stay in his studio and make art. I'd love to meet someone with a similar sense of adventure to mine. For the first time in two years, I was being honest with myself about what I really wanted - listening to those voices that we all have inside our heads, and too often try to muzzle. So did philosophy save me? Well, I'm now dating a travel writer I have to run to keep up with. I still haven't got over the fact that my replacement came from Cleveland, Ohio. But I guess I never will.

As a research analyst, stockbroker and fund manager, he'd made a lot of valuable contacts, earnt a lot of cash, and learnt some important business skills. However, as he approached his mid-thirties, he no longer felt good about himself or what he did for a living, and he found his colleagues cold and unfriendly. A chronic illness made him realise his mortality, and he began to reassess his priorities. Danny had been struggling with his career conundrum for nearly five years when he met David Arnaud, a philosophical counsellor. After a few soul-searching sessions, Danny arrived at a decision. Today, he teaches economics to sixth-formers, and he loves it. 'It's a much better lifestyle,' he says. Many people are turning to philosophical counsellors to get answers to questions such as: 'How do I make sense of myself?' 'What is important to me?' 'Where am I going?' These are perhaps not the sort of questions that require psychiatric intervention, but Arnaud, who recently completed the first empirical study of philosophical counselling in the UK, has found that within just five sessions the majority of clients, with important decisions to make, tend to move from a state of concern and confusion to a resolution. Modern philosophical counselling can be traced back to 1981, when the philosopher Gerd Achenbach opened the first practice near Cologne. Achenbach referred to the new discipline as 'therapy for the sane.' Today, there are hundreds of philosophical counsellors around the world, with the movement particularly strong in the US, Britain and the Netherlands. 'The dilemmas people face aren't always primarily psychological,' says Alex Howard, a philosophical counsellor from Newcastle. 'If people face problems that are social or economic, it doesn't make sense to define their problems in purely psychological terms.' Tim LeBon, a founder member of the Society for Philosophy in Practice (SPP) and author of Wise Therapy, adds: 'We are faced with far more life choices than our grandparents, yet have far fewer resources to deal with them. Our grandparents may have gone to a priest or to other family members for advice; most people don't trust these solutions any more and so want to make their own well-informed, well thought-out choices. Philosophical counselling can help these people - people in mid-life crises who are wondering how to make the most of the rest of their life. People who want to take stock of their values.' Where stressed executives might once have been prescribed a course of tranquillisers or antidepressants, they can now get a dose of Bertrand Russell instead: 'Success is too dearly purchased if all the other ingredients have been sacrificed to obtain it.' While some philosophical counsellors do recommend books for their clients to read, most sessions are about helping the client identify faulty thoughts. For example, a briefing in Aristotelian logic might show a client why their beliefs are erroneous. The person might infer that they're a screw-up because they've screwed up. The counsellor could point out that they're making an error called 'fallacy of composition' - that is, what's true of the part isn't necessarily true of the whole. In philosophical counselling, problems aren't pathologised as they are by the psychiatric profession, and the dialogue between client and counsellor is more like a meeting of equals, compared to many therapies where the client is treated like a patient and seen as someone who is, in some way, inadequate. 'Anybody can benefit from philosophical counselling,' says Howard. 'But it does require someone who is willing to take stock.' Lou Marinoff, author of international bestseller Plato Not Prozac! has done much to promote philosophical counselling. 'Some people who have stabilised their neurochemistry and validated their emotions now wish to examine or re-examine the criteria of their beliefs, the principles of their conduct, or the meaning of their lives,' he says. 'With whom shall they do this? Psychologists and psychiatrists can shed light on such issues - as can rabbis, priests, imams and gurus. Philosophers are now rejoining the ranks of helpers.' LeBon believes certain therapies (such as cognitive behavioural therapy) don't go far enough in helping their clients. 'For instance, if you are anxious about your relationship, a cognitive therapist would try to dispute your catastrophising and jump to conclusions to make you feel less anxious,' says LeBon. 'A philosophical counsellor would do this, but would also look for existential meaning in your anxiety - perhaps you really don't want to be in the relationship and that is what your anxiety is telling you.' LeBon also gives short shrift to psychoanalysts. 'There's very little evidence for the Freudian unconscious, and it's time to move on to more intellectually satisfying and helpful therapies,' he says. However, Alain de Botton, the man who popularised philosophy as self-help, isn't ready to bury psychologists and their ilk just yet. 'The truth is that psychoanalysis grew out of philosophy - it's not some completely new idea, and in fact, done properly, psychoanalysis is philosophical anyway. It may even be dangerous to the mental health of some people to suggest a philosopher rather than a properly trained analyst. The knowledge of analysts when it comes to many emotional problems is now much greater than that of most philosophers.' Guardian Unlimited © Guardian Newspapers Limited 2004. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy: chronological snobbery (CS). First described by the Christian academic Owen Barfield in the 1920s and later popularized by his friend and colleague C.S. Lewis, the fallacy of CS presupposes that cultural, philosophical, or scientific ideas from later time periods are necessarily superior to those from earlier ages. Grounded on the Enlightenment's concept of “progress”, this informal fallacy stems from the assumption that the ever‐increasing amount of knowledge in (...) society naturally and perpetually replaces all outdated, disproven ideas with updated, better‐justified beliefs, therefore making old ideas incorrect or irrelevant simply because they are old. Essentially the opposite of the appeal to ancient authority, CS relates to guilt by association, hasty generalization, and poisoning the well fallacies whenever it references unrelated false beliefs held by individuals from the originating time period.

Knobe relies on unhelpful analogies in stating his main thesis about the mind. It isn't clear what saying the mind works, or doesn't work, or means. We suggest he should say that some think that human cognition respects a ban on fallacies of relevance, where considerations actually irrelevant to truth are taken as evidence. His research shows that no such ban is respected.

On the hermeneutic. Palmer declares it unnecessary to recover Parmenides’ original authorial intentions in performing his poem ). It is “simply a mistake—one might term it the ‘essentialist fallacy’—to privilege Parmenides’ intended meaning as the determining factor in his subsequent influence”. Here the claim is not the one that authorial intention is irrecoverable, but the quite different claim that it is an “error vitiating most appraisals of this influence [of Parmenides on Plato to make] the assumption that one can base (...) an appraisal upon an interpretation of Parmenides developed independently of the actual Platonic reception”. And it is thus Palmer’s claim that most previous studies of what I above termed ‘the Plato-Parmenides connection’ have tacitly assumed that we can guess at how Plato received Parmenides by starting with our own interpretations of Parmenides. Stated in this way, the hermeneutic is original and quite acceptable, indeed necessary. But if exaggerated into the intention, say, to comment only on those parts of Parmenides used by Plato utterly without any attempt to read them as they might have carried meaning for Parmenides himself, such a hermeneutic would rule out even Palmer’s own procedure. For example, Palmer reads the second ‘deduction’ of the second half of the Parmenides as corresponding to what the historical Parmenides himself meant in sentences like “Both Parmenides himself and Plato’s Parmenides then draw the conclusion that Being/the One is equal to itself”. One must therefore proceed with care, as Palmer does in the sentence I have just quoted. Palmer cannot mean that the meaning of Parmenidean words or the use or construction of Parmenidean sentences is “largely irrelevant” to a study of how Plato ‘receives’ Parmenides. (shrink)

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)

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.

This work is, in large part, a series of refutations; it is also the author's Ph.D. thesis. First to be refuted is Russell's vicious circle principle as a general remedy for the solution of the paradoxes. The author rejects the classification of paradoxes into syntactic and semantic, since in his view there are no purely syntactic paradoxes. The distinction in logic between the uninterpreted syntactical aspect of a system and the system when given a determinate interpretation is held to be (...) untenable. Tarski's distinction between object-language and meta-language and his concept of semantically closed language are considered irrelevant for the solution of the Liar paradox. The author claims that the usual versions of the Liar paradox have the same structure as the Barber paradox, viz., [S ↔ ~S]. The author solves the Liar paradox by pointing out that it does not have a proper reference. Cantor's diagonal argument for the indenumerability [[sic]] of the real numbers is labeled as unsatisfactory. Since the diagonal number is dependent upon the real numbers in the constructed list, the author claims that this makes the diagonal number to be of a different nature and status than the real numbers in the list; thus we have what the author calls the dependence fallacy. The author also refuses to accept Cantor's nested interval proof of the indenumerability [[sic]] of the real numbers. Within the proof, two infinite sequences are constructed, each of which converges to a limit. Because the proof does not give a "definite rule of convergence," the author is not satisfied that the infinite sequences converge. Also rejected is Cantor's theorem. Other paradoxes analyzed are the Berry, Richard, heterological, "Richardian", Russell, Cantor, and Burali-Forti paradoxes.--T. G. N. (shrink)

This paper aims to reexamine the axiom of the independence of irrelevant alternatives in the theory of social choice. A generalized notion of independence is introduced to clarify an informational requirement of binary independence which is usually imposed in the Arrovian framework. We characterize the implication of binary independence.

One would like to be able to say that a large part of the material in this book is so obvious as to be unnecessary. Unfortunately, this book is worthwhile precisely because one cannot. Bandman's problem may be stated as follows: By what canons and criteria does one evaluate arguments in the philosophy of education? How, in particular, do we correctly evaluate arguments about what ought to be taught? The book is thus an exercise in the "metaphilosophy" of education. In (...) the first, polemical half of the volume the author convincingly demonstrates that numerous and typical patterns of argument employed in the philosophy of education by many authors violate some of the most basic and pervasive logical rules. The really striking thing here is that Bandman persuasively charges numerous well respected educational thinkers with informal fallacies that a freshman logic student would not commit. The constructive side of Bandman's work is a bit more dubious. Initially, he distinguishes between two senses of "argument": Sense I and Sense II. These are, respectively, a "special evaluative type of argument, which does not intend to demonstrate the conclusion, and is used in giving intellectual backing to [it]," and the usual sense of argument common to formal logic. Bandman's thesis is that arguments in Sense I are "capricious," inconclusive, and typically unsound, while educational arguments in Sense II are either unsound or irrelevant. He proposes a middle way between the horns of this dilemma by urging a third sense of "argument" as the provision of "good enough" and "cogent" reasons. At least two lines of attack on Bandman's position are available. In the first place, in dismissing the utility of Sense II arguments, he makes rather facile use of the noncognitivist view that moral statements are neither true nor false. Secondly, Bandman does not adequately spell out his Sense III notion of "argument," and the few necessary conditions that he does provide fail to clarify in what sense the premisses support the conclusion and how Sense III really differs from Sense I. Despite these criticisms, the merits of the book are many, and it deserves a wide reading by philosophers and educators alike.—H. P. K. (shrink)

William C. Frederick proposes a naturalistic business ethics. Many commentators focus on the issues of naturalistic fallacy, deprivation of freedom of the will, and possibility of important and universal moral values in business ethics. I argue that an ethics being naturalistic is not a worry. The issue of deprivation of free will is irrelevant. Yet there are urgent questions regarding the possibility of important and universal moral values, which may prevent Frederick’s view from getting off the ground.

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 present study focuses on the so-called ‘fallacy of combination and division’ or ‘synthetic-dieretic fallacy,’ as discussed by Aristotle in his treatises ‘Rhetoric’ and ‘On Sophistical Refutations.’ Despite significant scholarly interest in these manipulative maneuvers over the last two decades, there is no agreement regarding the notable discrepancies observed in the two works regarding defini- tions and the examples the philosopher employs to illustrate them. The thesis to be defended is that these are not two entirely different phenomena but rather (...) two dis- tinct approaches applied by Aristotle to refute the paradoxes used in the Megarian school of philosophy to seemingly disprove the concept of the static (εἶναι) nature of being and ‘prove’ their idea of an eternally changing dynamic world (γίγνεσθαι). A new approach will be proposed towards the specific argumentative fallacies and linguistic means underlying the logic-linguistic phenomena described by Aristotle. (shrink)

Lately, a number of referee decisions appear to have reignited the debate over the need to bring more in-game officiating technology into soccer. The fallacies behind the arguments for the inclusion of technology to aid game officials can be narrowed down to those behind current arguments for or against goal-line technology. Both the proponents and opponents of these arguments appear to overemphasise the role of referees to the point of claiming that if refereeing errors could be eliminated in goal-line (...) situations, then the most deserving team would most of the time be expected to win the contest. While we firmly believe that the game of soccer would benefit immensely from infallible officiating, we intend to show that these arguments are founded upon a number of inconspicuous assumptions. First, they assume that goal-line situations can be shown to affect the outcomes of games more than all other game situations. This can easily be shown to be a myth, since goals can be scored from all areas of the playing field. In addition, winning a soccer game, obviously, involves more than just scoring goals. Second, these arguments seem to support the view that referee decisions affect the outcomes of games more than decisions made by players, coaches and managers. This is merely a myth, since one can show that, in light of Cesar Torres's insights, referee involvement in game is limited to regulating situations that demand that the game be restored to its constitutive actualisation. Third, most arguments for goal-line technology tend to support the erroneous view that technology can actually eliminate most ?crucial? human mistakes from sport and, thus, ensure fairness of game outcomes. Such a myth can easily be refuted by reference to numerous cases of inconclusive slow-motion video replays in soccer. Therefore, this paper aims at arguing that, instead of reinforcing the scapegoating of referees and overemphasising the importance of isolated referee decisions to the point of attributing victory or defeat to these ?crucial? decisions, both sides of the goal-line technology debate need to put forth compelling arguments which go beyond the current misguided search for referee infallibility.

Although the fallacy of composition is little studied and trivially illustrated, some view it as ubiquitous and paramount. Furthermore, although definitions regard the concept as unproblematic, it contains three distinct elements, often confused. And although some scholars apparently claim that fallacies are figments of a critic’s imagination, they are really proposing to study fallacies in the context of meta-argumentation. Guided by these ideas, I discuss the important historical example of Michels’s iron law of oligarchy.

I focus on an overlooked aspect of the challenge of irrelevant influences. The challenge is often framed in terms of whether recognizing the presence of irrelevant factors in the pedigree of a belief provides a defeater. I argue that the epistemic significance of irrelevant factors goes beyond their status as defeaters. I focus on what I call gray cases, where learning about such factors causes epistemic worry without justifying giving up the belief. I argue that in gray cases, the subject (...) finds a commendatory epistemic practical reason to engage in an activity intended to assuage that epistemic worry. (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 fallacy of composition involves differing relationships of parts to wholes complicated by the problem of group ambiguity. Our discussion begins with a brief diagnosis of important features of the fallacy. We consider a common implicit assumption and the main factors that contribute to its acceptability. Our focus will be on illuminating some common strategies rather than formal material conditions for the fallacy. This is to facilitate the critical discussion of possibilities for this fallacy.

Much of the appeal of deliberative democracy lies in its emancipatory promise to give otherwise disadvantaged groups a voice, and to grant them influence through reasoned argument. However, the precise mechanisms for delivery of this promise remain obscure. After reviewing Habermas's formulation of deliberation, the article draws on recent theories of argumentation to provide a more detailed account of such mechanisms. The article identifies the key emancipatory mechanism as explicitness in language. It outlines the primary modalities of this mechanism: expressing (...) differences of opinion, mobilising a shared standard of inference, and recognising and excluding fallacious appeals to irrelevant factors such as force or authority. It describes how these modalities are enhanced at a secondary, reflexive level that recognises the partiality and defeasibility of particular argumentative exchanges. Such qualifications, it is argued, support a model of deliberation across discourses that allows a clearer appreciation of its potential and limits. (shrink)

This chapter deals with fallacies that appeal to pity. Sometimes evoking pity can be a legitimate part of arguing, particularly if emotion is part of what is at issue. However, often appeals to pity in Western philosophy are irrelevant to the point at issue and are fallacious attempts to convince an audience to accept one's argument/position. Thus, a central problem in regard to appeal to pity arguments is figuring out when such appeals are legitimate and when they're fallacious. The (...) two basic issues relevant to considering whether an appeal to pity is fallacious are: what exactly is the conclusion, and what is the understood point of the dialogue. The chapter looks at some examples to illustrate the meaning and use of these questions. (shrink)
