In this overview article, we first explain what we take informal logic to be, discussing misconceptions and distinguishing our conception of it from competing ones; second, we briefly catalogue recent informal logic research, under 14 headings; third, we suggest four broad areas of problems and questions for future research; fourth, we describe current scholarly resources for informal logic; fifth, we discuss three implications of informal logic for philosophy in particular, and take note ofpractical consequences of a more general sort.

Coalescent argumentation is a normative ideal that involves the joining together of two disparate claims through recognition and exploration of opposing positions. By uncovering the crucial connection between a claim and the attitudes, beliefs, feelings, values and needs to which it is connected dispute partners are able to identify points of agreement and disagreement. These points can then be utilized to effect coalescence, a joining or merging of divergent positions, by forming the basis for a mutual investigation of non-conflictual options (...) that might otherwise have remained unconsidered. The essay proceeds by defining and discussing ‘argument’, ‘position’ and ‘understanding’. These notions are then brought together to outline the concept of coalescent reasoning. (shrink)

There is a widely held concern that using war and sport metaphors to describe argument contributes to the breakdown of argumentative processes. The thumbnail version of this worry about such metaphors is that they promote adversarial conceptions of argument that lead interlocutors with those conceptions to behave adversarially in argumentative contexts. These actions are often aggressive, which undermines argument exchange by either excluding many from such exchanges or turning exchanges more into verbal battles. These worries are legitimate as far as (...) they go, and given that well-run argumentation is a good thing, we would be remiss not to consider whether our vocabulary inhibits argument's proper functioning. ..

This essay argues that ideals of cooperation or adversariality in argumentation are not equally attainable for women. Women in argumentation contexts face oppressive limitations undermining argument success because their authority is undermined by gendered norms of politeness. Women endorsing or, alternatively, transgressing feminine norms of politeness typically defend their authority in argumentation contexts. And yet, defending authority renders it less legitimate. My argument focuses on women in philosophy but bears the implication that other masculine dis- course contexts present similar double (...) binds that urge social and political change. (shrink)

An introduction to philosophy of language since Frege, focusing on the 20th century.

Minimal adversariality consists in the opposition of contradictory conclusions in argumentation, and its usual metaphorical expression as a game between combating arguers has seen it be criticized from a number of perspectives: the language used, whether cooperation best attains the argumentative telos of epistemic betterment, and the ideal nature of the metaphor itself. This paper explores primarily the idealization of deductive argumentation, which is problematic due to its attenuated applicability to a dialectic involving premises and justificatory biases that are left (...) hidden and unelucidated. To clarify the issue and offer up a solution, we consider minimal adversariality as an involuntary state of affairs before relating this interpretation to a link between rational persuasion and the attainment of epistemic betterment. Through this we see how the idealizing tendencies of minimal adversariality can be reduced even in argumentation involving premises whose justifications for any arguer are inaccessible to any other arguer.

Since at least the 1980s, the role of adversariality in argumentation has been extensively discussed within different domains. Prima facie, there seem to be two extreme positions on this issue: argumentation should never be adversarial, as we should always aim for cooperative argumentative engagement; argumentation should be and in fact is always adversarial, given that adversariality is an intrinsic property of argumentation. I here defend the view that specific instances of argumentation are adversarial or cooperative to different degrees. What determines (...) whether an argumentative situation should be primarily adversarial or primarily cooperative are contextual features and background conditions external to the argumentative situation itself, in particular the extent to which the parties involved have prior conflicting or else convergent interests. To further develop this claim, I consider three teloi that are frequently associated with argumentation: the epistemic telos, the consensus-building telos, and the conflict management telos. I start with a brief discussion of the concepts of adversariality, cooperation, and conflict in general. I then sketch the main lines of the debates in the recent literature on adversariality in argumentation. Next, I discuss the three teloi of argumentation listed above in turn, emphasizing the roles of adversariality and cooperation for each of them. (shrink)

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

It has been accepted for some time within Communication Theory that there are identifiable differences in how men and women communicate. This acceptance obtains both within the academic world and even more so within the realm of folk Communication Theory. I argue that the gender-identified differences run along distinct poles. The first major pole concerns the objectives meant to be achieved by argument: is it deciding who is right? Or, what the issue really is? Or, how a disagreement can or (...) should be resolved? The second major aspect concerns the communi­cative tools used in settling differences and understanding positions. If the genders have different rules of communi­cation, which rules will be followed? What sorts of arguments and evidence will be allowed? If classically mascu­line criteria are applied, then how can classically feminine voices be heard? It is argued that these issues do not loom nearly so large when gender is not confused with sex.

A simple way to approach fallacies is to ask, "Has reasoning-strategy X retarded or halted the growth of knowledge?" and seek uncontroversial historical events as empirical support for the fallacy moniker. Historical support also offers a means of retiring reasoning strategies heretofore thought fallacious—they are wrongly accused if they helped drive knowledge. Finally, this approach allows us to be more critical of our argumentative practices. Evidence is offered for an Intuitive Fallacy: In its extreme form it rules out the possibility (...) of evidence; in its weaker form, it is a non-response to evidence that appears to be a response.

Philosophy’s adversarial argumentation style is often noted as a factor contributing to the low numbers of women in philosophy. I argue that there is a level of adversariality peculiar to philosophy that merits specific feminist examination, yet doesn’t assume controversial gender differences claims. The dominance of the argument-as-war metaphor is not warranted, since this metaphor misconstrues the epistemic role of good argument as a tool of rational persuasion. This metaphor is entangled with the persisting narrative of embattled reason, which, in (...) turn, is linked to the sexism-informed narrative of the “man of reason” continually warding off or battling “feminine” unreason.

Three misrepresentations of informal and formal logic by two feminist writers are discussed. Andrea Nye's criticism that the semantics for formal logic abstracts from context is a misrepresentation of formal logic because Nye ignores the development of intensional logics. Second, Nye's criticism that informaIlogicians ignore the origins of arguments is a misrepresentation of fallacy theory. Prominent writers in the field specifiy numerous cases where the origins of an argument are relevant to its evaluation. Third, Valerie Plumwood's criticism that negation in (...) classical logic rests on an exclusivistic dualism that encourages the exclusion of women is shown to be false. (shrink)

Open Access: I rely on Nel Noddings’ analysis of receptivity as "an essential component of intellectual work," to argue that receptivity is a virtue of argumentation, practicing the principle of charity excellently for the sake of an author and their philosophical community. The deficiency of receptivity is epitomized by the philosopher who listens to attack. The excess of receptivity is the vice of insufficiently critical acceptance of an author regardless of the merits of an argument.

In traditional analytic philosophy, critical thinking is defined along Cartesian lines as rational and linear reasoning preclusive of intuitions, emotions and lived experience. According to Michael Gilbert, this view – which he calls the Natural Light Theory (NLT) – fails because it arbitrarily excludes standard feminist forms of argumentation and neglects the essentially social nature of argumentation. In this paper, I argue that while Gilbert’s criticism is correct for argumentation in general, NLT fails in a distinctive and particularly problematic manner (...) in moral argumentation contexts. This is because NLT calls for disputants to adopt an impartial attitude, which overlooks the fact that moral disputants qua moral agents are necessarily partial to their own values and interests. Adopting the impartial perspective would therefore alienate them from their values and interests, causing a kind of “moral schizophrenia.” Finally, I urge a re-valuation of epistemic virtue in argumentation.

Is argumentation essentially adversarial? The concept of a devil's advocate—a cooperative arguer who assumes the role of an opponent for the sake of the argument—serves as a lens to bring into clearer focus the ways that adversarial arguers can be virtuous and adversariality itself can contribute to argumentation's goals. It also shows the different ways arguments can be adversarial and the different ways that argumentation can be said to be "essentially" adversarial.

Feminist argumentation theorists have criticized the Dominant Adversarial Model in argumentation, according to which arguers should take proponent and opponent roles and argue against one another. The model is deficient because it creates disadvantages for feminine gendered persons in a way that causes significant epistemic and practical harms. In this paper, I argue that the problem that these critics have pointed out can be generalized: whenever an arguer is given a role in the argument the associated tasks and norms of (...) which she cannot fulfill, she is liable to suffer morally significant harms. One way to react to this problem is by requiring arguers to set up argument structures and allocate roles so that the argument will be reasons-reflective in as balanced a way as possible. However, I argue that this would create to heavy a burden. Arguers would then habitually have to take on roles that require them to divert time and energy away from the goals that they started arguing for and instead serve the goal of ideal reasons-reflectiveness. At least prima facie arguers should be able to legitimately devote their time and energy towards their own goals. This creates a problem: On the one hand, structures that create morally significant harms for some arguers should be avoided—on the other hand, arguers should be able to take argument-roles that allow them to devote themselves to their own argumentative goals. Fulfilling the second requirement for some arguers will often create the morally significant harms for their interlocutors. There are two possible solutions for this problem: first, arguers might be required to reach free, consensual agreements on the structure they will adopt for their argument and the way they will distribute argumentative roles. I reject this option as both fundamentally unfeasible and practically unrealistic, based on arguments developed by theorists like Krabbe and Jacobs. I argue that instead, we should take a liberal view on argument ethics. Arguers should abide by moral side constraints to their role taking. They should feel free to take roles that will allow them to concentrate on their argumentative goals, but only if this does not create a situation in which their interlocutors are pushed into a role that that they cannot effectively play.

The emergent field of cultural studies uses various critical-emancipatory frameworks to evaluate theory and practice in philosophy and other disciplines. As part of a larger project incorporating feminist, postcolonial, Marxist, and black African critical philosophies, this essay selectively highlights certain aspects of argumentation analysis which share characteristics with dominating modes of thought. Pragma-dialectic theory is focused upon, chosen due to its progressive methodology within the context of argumentation study, and its explicit commitment and sensitivity to higher-order goals such as equality (...) between arguers. Specifically, the Pragma-dialectic method of reconstruction termed "addition" and the notion of the "ideal arguer" are analyzed, showing areas where higher-order conditions may be compromised at the same time as they are assumed by the Pragma-dialectic model of ideal argument. A brief consideration of Coalescent argumentation as an alternative theory less bound by dominating tendencies, is presented in conclusion. (shrink)

The paper addresses the manner in which the theory of Coalescent Argumentation [CA] has been received by the Argumentation Theory community. I begin (section 2) by providing a theoretical overview of the Coalescent model of argumentation as developed by Michael A. Gilbert (1997). I next engage the several objections that have been raised against CA (section 3). I contend that objectors to the Coalescent model are not properly sensitive to the theoretical consequences of the genuinely situated nature of argument. I (...) conclude (section 4) by suggesting that the resolution to the dispute between Gilbert and his objectors hinges on the outcome of several foundational theoretical questions identified over the course of the paper.

How is it possible that biases are cognitive vices, objectivity is an exemplary intellectual virtue, and yet objectivity is itself a bias? In this paper, we argue that objectivity is indeed a kind of bias but is still an argumentative virtue. In common with many biases – and many virtues – its effects are neither uniformly negative nor uniformly positive. Consequences alone are not enough to determine which character traits are argumentative virtues. Context matters. The opening section addresses the problem (...) of identifying argumentative virtues and provides a preliminary response to recent questions from Goddu and Godden regarding the foundations of virtue-based argumentation theories. The middle section analyzes courtroom argumentation as a case study. The assigned roles in legal settings provide high-definition examples of how the roles that all arguers routinely inhabit in ordinary argumentation factor into the evaluation of virtues. The contextually variable values of objectivity and biases are on clear display. The final section employs the conclusions from the middle section to answer the questions from the first section and to complete the argument that objectivity can be an occasionally “vicious virtue”.

In Coalescent Argumentation, Michael Gilbert criticizes the "Critical-Logical Model" which he claims focuses on truth and treats arguments a-contextually; he proposes an alternative theory of coalescent argumentation which focuses on cont ent and consensus. I shall examine the dispute between the C-L and the coalescent models using the coalescent approach, thereby attempting to find which points of contention are real disagreements and which are only peripheral or apparent. Finally, I sh all examine the extent to which this examination, undertaken using (...) the coalescent model, differs from what would have been done using a C-L model. (shrink)

When evaluating the arguer instead of the argument, we soon find ourselves confronted with a puzzling situation: what seems to be a virtue in one argumentative situation could very well be called a vice in another. This paper will present the idea that there are in fact two sets of virtues an arguer has to master—and with them four sometimes very different roles.

It is no accident that we begin this article with a quotation from Marek Tokarz. His article entitled Komunikacja poza gramatyką [eng. Communication beyond grammar], which was published in the commemorative book in honor of professor Jerzy Pelc W świecie znaków: księga pamiątkowa ku czci profesora Jerzego Pelca, was one of the chief inspirations for this paper. In his article, Tokarz studied the possibility of achieving communication without syntax. In what follows, we intend to go one step further and analyze (...) the possibility of achieving communication without verbal means. Let us begin with specifying the term ’nonverbal communication’. According to the common definition, it is a communication which involves giving signs other than words. Verbal communication is not identified with oral, spoken communication, but with a communication established through words. That is why emitting sounds such as muttering or humming are considered nonverbal messages. On the other hand, sign language and written language are treated as verbal communication. (shrink)

I will connect the literature on deep disagreements with the literature on trust to construct a two-dimensional picture of the limits of argument. Argumentation and trust are important to the functioning of society, but each sets different expectations for when arguments can and should be used to resolve disagreements. When trust is factored in, we see a more nuanced picture of which disagreements will remain too deep for objective argument. Affective and social aspects of argument are not independent of procedure (...) and content. (shrink)

Though a segment of feminists have questioned the combative, logical, objective nature of academic writing and presentation, their critique has seldom extended to the most widely used model in composition and communication, Stephen Toulmin’s Informal Model of argument, which terminologically relates to combative, logical and legal terminologies. Toulmin’s model, however, adapted to a visual rather than legal metaphor, fits well with the less confrontational, more personal and contextual approach espoused by some feminists and many argument theorists. This essay offers an (...) adaptation of Toulmin’s six-part model based in a visual metaphor, adding three more parts: ‘Interrelated Perceptions’ ; and ‘Historical/Cultural Horizon,’ (using Gadamer’s, 1989, hermeneutical historical concept to further contextualize arguments. The model then responds to two key feminist and argumentation theorist concerns, replacing the argument-as-war metaphorical mapping of argument relations, and personalizing and contextualizing arguments as to historical, social, and cultural situation.

The relevance of feminism for argumentation has been the subject of lively debates recently. I explore the viability of applying feminist categories to argumentation with a focus on the relevance of gender in reasoning and rationality. Arguing from the view that particular practices of reasoning are gendered, as operating within a gendered socio-political context, I examine the implications of conditioned reasoning for a conception of reason. Are reasoning and rationality in some fundamental sense conditioned, e.g., gendered? I argue for a (...) conceptualization of reason as a structural complex whose character can be conditioned yet is non-relativistic. (shrink)
