34A Defense of Conduction: A Reply to AdlerArgumentation 30 (2): 109-128. 2016.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 characterizat…Read more

65Probative Norms for Multimodal Visual ArgumentsArgumentation 29 (2): 217-233. 2015.The question, “What norms are appropriate for the evaluation of the probative merits of visual arguments?” underlies the investigation of this paper. The notions of argument and of multimodal visual argument employed in the study are explained. Then four multimodal visual arguments are analyzed and their probative merits assessed. It turns out to be possible to judge these qualities using the same criteria that apply to verbally expressed arguments. Since the sample is small and not claimed to b…Read more

22Even with Kientpointer's and Walton's valuable work, we do not yet have a complete theory of argument schemes. A complete theory of argument schemes should contain at least the following: its theoretical motivation, the denotation of "argument" or "ar gumentation" used in the theory, an analysis of the concept of an argument scheme, a theory of classification of argument schemes, a solution to the problem of identifying which scheme is correct, and an account of the grounds of the normativity or…Read more

28Are 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.

27Premissary relevanceArgumentation 6 (2): 203-217. 1992.Premissary relevance is a property of arguments understood as speech act complexes. It is explicable in terms of the idea of a premise's lending support to a conclusion. Premissary relevance is a function of premises belonging to a set which authoritatively warrants an inference to a conclusion. An authoritative inference warrant will have associated with it a conditional proposition which is true— that is to say, which can be justified. The study of the Aristotelian doctrine of topoi or argumen…Read more

100Walton's Argumentation Schemes for Presumptive Reasoning: A Critique and Development (review)Argumentation 15 (4): 365-379. 2001.The aim of the paper is to advance the theory of argument or inference schemes by suggesting answers to questions raised by Walton's Argumentation Schemes for Presumptive Reasoning (1996), specifically on: the relation between argument and reasoning; distinguishing deductive from presumptive schemes, the origin of schemes and the probative force of their use; and the motivation and justification for their associated critical questions.

142Argumentation as Rational PersuasionArgumentation 26 (1): 71-81. 2012.I argue that argumentation is not to be identified with (attempted) rational persuasion, because although rational persuasion appears to consist of arguments, some uses of arguments are not attempts at rational persuasion. However, the use of arguments in argumentative communication to try to persuade is one kind of attempt at rational persuasion. What makes it rational is that its informing ideal is to persuade on the basis of adequate grounds, grounds that make it reasonable and rational to ac…Read more

63Norms and Functions in Public Sphere ArgumentationInformal Logic 25 (2): 139-150. 2005.This paper is a commentary on the articles by William Rehg and Robert Asen in this issue of Informal Logic. It compares the subject matter of the two papers, offers an interpretation of and commentary on each paper separately, then discusses their overlapping problematic: the importance of public sphere argumentation
