There is no concept more central to logic and critical thinking than the concept of an argument. I here address the definition of ‘argument’ in the logical sense of the term and defend the claim that many current proposals, once they are interpreted in a way that makes them sufficiently precise, are extensionally inadequate. Definitions found in some contemporary, prominent critical thinking textbooks will serve as a springboard. I claim that each may be interpreted in an absolutist way or a (...) relativistic way, yet all turn out to be objectionable no matter which route is taken. I finish with a proposal on which the definition of ‘argument’ is an absolutist one, yet one that avoids the problems discussed for the earlier proposals. (shrink)

The human being is an imitative animal. This statement, or description, resonates across time and cultures. Its familiarity derives from its repetition. It has, in terms appropriate to this discussion, a memetic quality. What Aristotle says is that "imitation is natural to man from childhood, one of his advantages over the lower animals being this, that he is the most imitative creature in the world, and learns first by imitation". The proof for this, Aristotle goes on to explain, lies in (...) the pleasure derived from imitation. And if pleasurable, it is natural; we are naturally imitative creatures.Among our imitative practices is the social practice of argumentation with all its rhetorical... (shrink)

My purpose here is to describe a type of argument characterized by the fact that one of its premises is a directive—i.e. what is expressed by a directive sentence: a general instruction how to proceed or act. This directive premise brings an ostensive mechanism for the inclusion of visual or multimodal elements in an argument. If an argument is an invitation to inference, by using such a directive utterance the addresser is inviting the addressee to make an inference from an (...) image, not from a proposition. Hence I will call them arguments from ostension or from deixis. (shrink)

In recent discussions concerning the definition of argument, it has been maintained that the word ‘argument’ exhibits the process-product ambiguity, or an act/object ambigu-ity. Drawing on literature on lexical ambiguity we argue that ‘argument’ is not ambiguous. The term ‘argu-ment’ refers to an object, not to a speech act. We also examine some of the important implications of our argument by considering the question: what sort of abstract objects are arguments?

Formal logic has often been seen as uniquely placed to analyze mathematical argumentation. While formal logic is certainly necessary for a complete understanding of mathematical practice, it is not sufficient. Important aspects of mathematical reasoning closely resemble patterns of reasoning in nonmathematical domains. Hence the tools developed to understand informal reasoning, collectively known as argumentation theory, are also applicable to much mathematical argumentation. This chapter investigates some of the details of that application. Consideration is given to the many contrasting meanings (...) of the word “argument”; to some of the specific argumentation-theoretic tools that have been applied to mathematics, notably Toulmin layouts and argumentation schemes; to some of the different ways that argumentation is implicated in mathematical practices; and to the social aspects of mathematical argumentation.

This article challenges the view that rhetoric, dialectic and logic are three perspectives on argument, relating respectively to its process, its procedure, and its product. It also questions the view that rhetorical arguments represent a distinctive type. It suggests that, as related to argument, rhetoric is the theory of arguments in speeches, dialectics the theory of arguments in conversations, and logic the theory of good reasoning in each.

In this thesis I present an exploration into the concept of ‘argument’ in informal logic. I have separated the work into three major areas: the historical antecedents to the informal logicians, the Windsor group of informal logicians, and recent developments in informal logic and the concept of ‘argument.’ In doing so I provide insight into the concept of ‘argument’ within informal logic.

: In “What is a ‘Real’ Argument?” Geoff Goddu (2009) suggests and rejects four candidates for what a real argument is, concluding that argumentation theorists should abandon the idea that there is a theoretically significant sub-class of arguments that should be called real. In this paper, I argue against Goddu’s conclusion, finding that real arguments are arguments that are used or that have prospective use in the practice of thinking about matters that call for reasonable and reflective judgment concerning what (...) to believe or do. What makes these arguments theoretically distinct from arguments in general is that they are used or that they may be used in the pragmatic endeavor of attempting to establish good reasons for beliefs and actions. Real arguments are therefore the arguments that should be treated in a course that aims to improve the skills of argumentation that students might use outside of the classroom in real-life. (shrink)
