The aim of this investigation is to explore the role of argumentation schemes in enthymeme reconstruction. This aim is pursued by studying selected cases of incomplete arguments in natural language discourse to see what the requirements are for filling in the unstated premises and conclusions in some systematic and useful way. Some of these cases are best handled using deductive tools, while others respond best to an analysis based on defeasible argumentations schemes. The approach is also shown to work reasonably (...) well for weak arguments, a class of arguments that has always been difficult to analyze without the principle of charity producing a straw man.

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)

Following David Hitchcock and Stephen Toulmin, this paper takes warrants to be material inference rules. It offers an account of the form such rules should take that is designed (a) to implement the idea that an argument/inference is valid only if it is entitlement preserving and (b) to support a qualitative version of evidence proportionalism. It attempts to capture what gives warrants their normative force by elaborating a concept of reliability tailored to its account of the form such rules should (...) take. (shrink)

An examination of several approaches to the force of ‘probably’, when used to qualify the conclusions of arguments and inferences. Among the views examined are those of Toulmin and Wilfrid Sellars. The paper recommends taking the utterance of “Probably p’ to be licensing or authorizing the adoption of a particular doxastic attitude toward p, and offers a functional account of that particular doxastic attitude, namely expecting that p will turn out to be the case.

In this paper, I identify two sets of practical values of argumentation from a standpoint that places a premium on maximal participatory democracy. The first set includes pedagogical values for both teachers and learners. The second set of values are transformative and include: facilitating openness as both tolerance and opportunity; facilitating understanding of one’s own positions, other’s positions, and the conceptual frameworks underlying them; and, finally, fostering motivation by encouraging action.
