A convincing argument can change a discussant’s commitment regarding the acceptability of a claim, but the same effect can be achieved by examining evidence. Observing objects or events that count as evidence for or against the acceptability of a statement can change one’s commitment regarding that statement. If we speak of fallacies in the realm of convincing through argumentation, can we speak of fallacies in the realm of convincing through evidence? In this paper, we defend an affirmative answer. We introduce (...) and discuss the conceptual implications of evidentiary fallacies as fallacies committed when evidence is fabricated or suppressed during an attempt to resolve disagreement using proof. We then apply the notion of evidentiary fallacy to two real-life examples of mis-executed evidentiary procedures. We conclude that the notion of evidentiary fallacy can contribute to a more comprehensive fallacy theory and can foster new and broadly applicable critical skills. (shrink)

This special issue of Informal Logic brings together a num-ber of traditions from the psychology and philosophy of argument. Psycho-logists’ interest in argument typically arises in understanding how indivi-duals form and change their beliefs. Thus, theories of argument can serve as models of the structure of justi-fications for belief, as methods of diagnosing errors in beliefs, and as prototypes for learning. The articles in this issue illustrate all three of these connections.

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)

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

This essay begins with a brief description of my approach to the study of argumentation and fallacies which is empirical, historical-textual, dialectical, and meta-argumentational. It then focuses on the fallacy of composition and elaborates a number of conceptual definitions and distinctions: argument of composition; fallacy of composition; arguments and fallacies of division; arguments that confuse the distributive and collective meaning of terms; arguments from a property belonging to members of a group to its belonging to the entire group; several nuanced (...) schemes for arguments of composition; and several principles for the evaluation of such arguments. I then call attention to the fact that some scholars have claimed that the basic argument for global warming commits the fallacy of composition, and undertake a critical analysis of this claim. I show that the global-warming argument is not a fallacy of composition, but is rather a deductively valid argument of composition from the temperature of the parts to the temperature of the whole earth; moreover, I criticize the meta-argumentation of these scholars by showing that the global-warming argument is not similar to the one for global pollution, which is indeed fallacious; finally, I argue that these scholars confuse the global-warming argument with the argument claiming that all effects of global warming are harmful, which is indeed incorrect as a hasty generalization.

This is a critical appreciation of Govier’s 2006 ISSA keynote address on the fallacy of composition, and of economists’ writings on this fallacy in economics. I argue that the “fallacy of composition” is a problematical concept, because it does not denote a distinctive kind of argument but rather a plurality, and does not constitute a distinctive kind of error, but rather reduces to oversimplification in arguing from micro to macro. Finally, I propose further testing of this claim based on examples (...) involving public vs. private debt in economics; oligarchic tendencies in politics, and the emergence of societal wholes in sociology.
