An overview of the epistemological approach to argumentation, explaining what it is, justifying it as better than a rhetorical or a consensual ist approach.systematizing the main directions and theories according to their criteria for good argumentation and presenting their contributions to major topics of argumentation theory. Also. an introduction to the articles of the two special issues of Informal Logic about the epistemological approach to argumentation.

This paper addresses the problem posed by the current split between the two opposed hypotheses in the growing literature on the fallacy of begging the question the epistemic hypothesis, based on knowledge and belief, and the dialectical one, based on formal dialogue systems. In the first section, the nature of split is explained, and it is shown how each hypothesis has developed. To get the beginning reader up to speed in the literature, a number of key problematic examples are analyzed (...) illustrating how both approaches can be applied. Useful tools are brought to bear on them, including the automated argument diagramming system Araucaria, and profiles of dialogue used to represent circular argumentation in a dialogue tableau format. These tools are used to both to model circular reasoning and to provide the contextual evidence needed to properly determine whether the circular reasoning in a given case is better judged fallacious or not. A number of technical problems that have impeded the development of both hypotheses are studied. One central problem is the distinction between argument and explanation. It is concluded that the best way to move forward and solve these problems is to reformulate the two hypotheses in such a way that they might be able to co-exist. On this basis, a unified methodology is proposed that allows each hypothesis to move forward as a legitimate avenue for research using the same tools. (shrink)

(1) The aim of the paper is to develop a reduction of fallacy theory, i.e. to 'deduce' fallacy theory from a positive theory of argumentation which provides exact criteria for valid and adequate argumentation. Such reductionism has several advantages compared to an unsystematic action, which is quite usual in current fallacy but which at least in part is due to the poor state of positive argumentation theory itself. (2) After defining 'fallacy' (3) some principle ideas and (4) the exact criteria (...) for (argumentatively) valid and adequate arguments of the 'practical theory of argumentation' of the author are expounded. These criteria will be used as the positive basis for the following reduction. (5) In the main part of the paper a systematization, definition and explanation of the main types and many subforms of fallacies of argumentative validity and (6) adequacy is developed, following the list of positive conditions of validity and adequacy. In addition to many new types of fallacies, this systematization contains the most important of the traditionally known and named fallacies; these are explained and the criteria for some of them are corrected or put more precisely.

This paper criticizes Kent Wilson's (`Circular Arguments', 1988) arguments against the analysis of the fallacy of begging the question in epistemic terms and against the division of the fallacy into equivalence and dependency types. It is argued that Wilson does not succeed in showing that the epistemic attitude to the fallacy analysis should be given up. Further, it is argued that Wilson's arguments against the division of the fallacy into two types can be overcome by altering the accounts he criticizes (...) (David Sanford (1971, 1984, 1988) and John Biro (1977, 1984)): fallacy analysis should concentrate on externalized arguments, but this does not mean that either the epistemic attitude or the dependency conception should be given up.

Among contemporary philosophers, there is widespread consensus that begging the question is a grave argumentative flaw. However, there is presently no satisfactory analysis of what this flaw consists of. Here, I defend a notion of question-begging in terms of analyticity. In particular, I argue that an argument begs the question just in case its conclusion is an analytic part of the conjunction of its premises.

The argument diagramming method developed by Monroe C. Beardsley in his (1950) book Practical Logic, which has since become the gold standard for diagramming arguments in informal logic, makes it possible to map the relation between premises and conclusions of a chain of reasoning in relatively complex ways. The method has since been adapted and developed in a number of directions by many contemporary informal logicians and argumentation theorists. It has proved useful in practical applications and especially pedagogically in teaching (...) basic logic and critical reasoning skills at all levels of scientific education. I propose in this essay to build on Beardsley diagramming techniques to refine and supplement their structural tools for visualizing logical relationships in a number of categories not originally accommodated by Beardsley diagramming, including circular reasoning, reductio ad absurdum arguments, and efforts to dispute and contradict arguments, with applications and analysis.

This paper tries to reconcile the clash between argumentation theory and formal logic regarding circular arguments, which are regarded as the fallacy of begging the question by the former, and a benign and useful inference pattern by the latter. This paper provides a formal system which can represent circular arguments found in the literature. The formal system makes it possible to distinguish two ways in which arguments can be circular. The first type of circularity, which is vicious, is when an (...) argument is based on an inference step which is (indirectly) supported by that inference step itself. The second kind of circularity, which is benign, occurs when one of the premises is the same proposition as the conclusion. The first type of circularity implies the second type of circularity, but not the other way round. This distinction is in line with other approaches to circular arguments. Analyzing selected examples from the literature shows the value of the formal system. (shrink)

I will first look at some of the existing literature on irresolvable conflicts, shortly discuss the fallacy of begging the question, and then examine some questions that irresolvable conflicts bring to surface with respect to this fallacy. In particular, I will argue that even though such conflicts invite an analysis of the fallacy based on the doubt of the opponent, an analysis in terms of justified belief of the arguer is preferable.

The dissertation examines the nature and epistemic implications of epistemic source circularity. An argument exhibits this type of circularity when at least one of the premises is produced by a belief source the conclusion says is legitimate, e.g. a track record argument for the legitimacy of sense perception that uses premises produced by sense perception. In chapter one I examine this and several other types of circularity, identifying relevant similarities and differences between them. In chapter two I discuss the differences (...) between internalist and externalist analyses of justification. I examine in detail foundationalist and non-foundationalist versions of internalism, and go on to consider how one might characterize externalism: either negatively, by denying particular internalist theses, or positively, in terms of a theory offering different conditions for justification. I discuss the views of reliabilist foundationalists at length. In chapter three I present the internalist objection to externalism that the latter mistakenly permit one to be justified in believing the conclusion of an epistemic source circular inference. I explain the externalists' response that it is not in virtue of their externalism that they permit epistemic source circularity but rather their foundationalism; thus, internalist foundationalists must permit epistemic source circularity as well. I evaluate the positions of several internalists, most of them explicitly foundationalists, and argue that they too cannot avoid permitting epistemic source circularity. In the final chapter I consider whether such circularity is vicious, even though both internalist and externalist foundationalists permit it. I argue that one can sustain an objection to epistemic source circularity by imposing a non-question-begging requirement on justification and explain how respecting this requirement leads one to a non-foundationalist view. I conclude by considering the objection that question-begging leads to a certain arbitrariness in belief formation that should give the foundationalist pause when it comes to determining, at the beginning of inquiry, which beliefs are justified and which are not. The dissertation is primarily concerned with making clear the possible skeptical and non-skeptical positions one can take towards epistemic source circularity. I do not argue for the truth of a particular metaepistemology. (shrink)
