In Jonathan Adler argued that conductive arguments, as they are commonly characterized, are impossible—that no such argument can exist. This striking contention threatens to undermine a topic of argumentation theory originated by Trudy Govier based on Carl Wellman and revisited by the papers in “Conductive argument, An overlooked type of defeasible reasoning”. I here argue that Adler’s dismissal of conductive arguments relies on a misreading of the term ‘non-conclusive’ used in the characterization of this type of reasoning and argument, and (...) that as a result, his refutation fails. However, Adler’s critique raises other questions about conductive arguments that have to be answered. (shrink)

In this paper I examine five distinctions between deductive and inductive arguments, concluding that the best of the five defines a deductive argument as one in which conclusive favorable relevance to its conclusion is attributed to its premises, and an inductive argument as any argument that is not deductive. This distinction, unlike its rivals, is both exclusive and exhaustive; permits both good and bad arguments of each kind; and is both useful and needed in evaluating at least some arguments.

A method of linguistically-oriented reasoning comprehension is proposed. It is based on semiological principles of text comprehension. Both content and form are essential for comprehending argumentative texts. A text recipient is viewed as a rational judge trying to detect all the components of the argument he/she considers and thus to see if the argument is consistent. Elementary and higher level argumentative units of the text are discovered by applying a modified S. Toulmin's model of argumentative functions. Validity and correctness of (...) arguments are established by means of a new – linguistic – interpretation of traditional syllogistic. (shrink)

In this paper, I propose that the inquiry known as a/the theory of argument is the “invention” of Trudy Govier, using that term in its rhetorical sense, viz., the process of choosing ideas appropriate to the subject. In her paper, “Is a Theory of Argument Possible?” Govier used the idea of theory of argument to focus her discussion on problems in argument analysis and evaluation that came to light in the 1970s and 1980s. The idea of a theory of argument (...) was already there but Govier “discovered” it in the sense that she made its potential clear. (shrink)

J. Anthony Blair is a prominent international figure in argumentation studies. He is among the originators of informal logic, an author of textbooks on the informal logic approach to argument analysis and evaluation and on critical thinking, and a founder and editor of the journal Informal Logic. Blair is widely recognized among the leaders in the field for contributing formative ideas to the argumentation literature of the last few decades. This selection of key works provides insights into the history of (...) the field of argumentation theory and various related disciplines. It illuminates the central debates and presents core ideas in four main areas: Critical Thinking, Informal Logic, Argument Theory and Logic, Dialectic and Rhetoric. (shrink)

This volume presents a selection of papers reflecting key theoretical issues in argumentation theory. Its six sections are devoted to specific themes, including the analysis and evaluation of argumentation, argument schemes and the contextual embedding of argumentation. The section on general perspectives on argumentation discusses the trends of empiricalization, contextualization and formalization, offers descriptions of the analytical and evaluative tools of informal logic, and highlights selected principles that argumentation theorists do and do not agree upon. In turn, the section on (...) linguistic approaches to argumentation focuses on the problem of distinguishing between explanation and argument, while also elaborating on the role of verbal indicators of argument schemes. All essays included in this volume point out notable recent developments in the study of argumentation. (shrink)

In this paper I argue that the debate over the purported distinction between deductive and inductive arguments can be bypassed because making the distinction is unnecessary for successfully evaluating arguments. I provide a foundation for doing logic that makes no appeal to the distinction and still performs all the relevant tasks required of an analysis of arguments. I also reply to objections to the view that we can dispense with the distinction. Finally, I conclude that the distinction between inductive and (...) deductive arguments is not one of the most important and fundamental ideas in logic, but rather is unnecessary. (shrink)

a recent paper, Fábio Perin Shecaira proposes a defence of Waller’s deductivist schema for moral analogical argumentation. This defence has several flaws, the most important of them being that many good analogical arguments would be deemed bad or deficient. Additionally, Shecaira misrepresents my alternative account as something in between deductivism and non-deductivism. This paper is both an attempt at solving this misunderstanding and an analysis and criticism of Waller and Shecaira’s forms of deductivism.

In this paper I review a number of Govier’s criticisms of the standard view of logic at the time she was developing her views about the nature of logic as it applies to the critique of arguments in natural language and the development of ways to teach skills in such critique. I argue that the concept of informal logic has emerged at least in part from those criticisms and Govier’s positive alternatives.

In this paper I focus on two contrasting concepts of deduction and induction that have appeared in introductory (formal) logic texts over the past 75 years or so. According to the one, deductive and inductive arguments are defined solely by reference to what arguers claim about the relation between the premises and the conclusions. According to the other, they are defined solely by reference to that relation itself. Arguing that these definitions have defects that are due to their simplicity, I (...) develop definitions that remove these defects by assigning a combination of roles to both arguers’ claims concerning the premises/conclusion relation and the relation itself. Along the way I also present and briefly defend definitions of both deductive and inductive validity that are significantly different from the norm. (shrink)

Are there any logical norms for argument evaluation besides soundness and inductive strength? The paper will look at several concepts or models introduced over the years, including those of Wisdom, Toulmin, Wellman, Rescher, defeasible reasoning proponents and Walton to consider whether there is common ground among them that supplies an alternative to deductive validity and inductive strength.

This paper defends the view that the classification of an argument as being deductive ought to rest exclusively upon psychological considerations; specifically, upon whether the argument's author holds certain beliefs. This account is justified on theoretical and pedagogical grounds, and situated within a general taxonomy of competing proposals. Epistemological difficulties involved in the application of psychological definitions are recognized but claimed to be ineliminable from the praetice of argumentation. The paper concludes by discussing embryonic arguments where the author's relevant beliefs (...) are not sufficiently fine-grained so as to accord the argument deductive or inductive status. (shrink)

This paper will describe what happened to the community of informal logicians between 1983 and 1987, when they started to interact with communication scholars, rhetoricians and Pragma-Dialecticians. Special attention will be paid to key events, such as the Second International Symposiums on Informal Logic, the founding of AILACT in 1983, the start of journal Informal logic in 1984, and the international conference on argumentation held at Amsterdam in 1986.

This tribute to the breadth and influence of Trudy Govier’s philosophical work begins with her early scholarship in argumentation theory, paying special attention to its pedagogical expression. Most people first encounter Trudy Govier’s work and many people only encounter it through her textbooks, especially A Practical Study of Argument, published in many editions. In addition to the work on argumentation that has continued throughout her career, much of Govier’s later work addresses social philosophy and the problems of trust and response (...) to moral wrongs. The introduction by Catherine Hundleby situates Govier’s research along the path of her unusual academic life. While following the timeline of Govier’s research publication, in this collection the authors build on her work and suggest certain new connections between her argumentation theory and social philosophy. A Practical Study of Argument, first published in 1985, situates Govier among a distinct segment of informal logicians whose concerns about teaching reasoning to post-secondary students orient their research, Takuzo Konishi argues. Moira Kloster evaluates Govier’s progress in the challenge of providing critical thinking education to diverse and changing social contexts. Shifting gears to social philosophy but still addressing education, Laura Elizabeth Pinto explores the significance of Govier’s work on trust for explaining the problem of “audit culture” for teaching. At the centre of this volume, social philosophy receives an abstract meta-ethical defense from Linda Radzik. Moving solidly into the domain of normative social philosophy, Alice MacLachlan reconsiders Govier’s condemnation of revenge by viewing it as a form of moral address, but she notes how revenge as an act of communication contrasts with argumentation in lacking the respect that Govier maintains is intrinsic to argumentation. MacLachlan ultimately agrees that revenge is morally indefensible. The practical challenges of addressing others in the aftermath of wrongdoing, especially in public contexts, can make it difficult to distinguish between victims and combatants or wrongdoers, Alistair Little and Wilhelm Verwoerd explain, and Kathryn Norlock argues that forgiveness is psychologically vexed too. People may recognize transformation to be in principle possible for all people, Norlock argues, and yet we may find the evidence regarding some particular evildoer sufficient to count that person as an exception. Finally Govier responds to the various papers. (shrink)
