Even with the lack of consensus on the nature of an argument, the thesis that explanations and arguments are distinct is near orthodoxy in well-known critical thinking texts and in the more advanced argumentation literature. In this paper, I reconstruct two rationales for distinguishing arguments from explanations. According to one, arguments and explanations are essentially different things because they have different structures. According to the other, while some explanations and arguments may have the same structure, they are different things because (...) explanations are used for different purposes than arguments. I argue that both rationales fail to motivate a distinction between arguments and explanations. Since these are the only rationales for distinguishing arguments from explanations that I am prepared to take seriously, I don’t see why we should exclude explanations from being arguments. (shrink)

In this paper, I respond to papers on my Manifest Rationality (2000) by Leo Groarke, Hans Hansen, David Hitchcock, and Christopher Tindale presented at the meetings of the Ontario Philosophical Society, October 2000. From the many useful challenges they have directed at my position, I have chosen to focus on two. The dominant issue raised by their papers concerns my definition of argument, and particularly problems with the idea of a dialectical tier. I have selected that as the first strand. (...) Second, several have raised questions that deal with the relationship between logic, rhetoric and dialectic. That is the second strand. (shrink)

This paper addresses the issue of the relationship between Ralph Johnson’s idea of dialectical tier and the critical scrutiny function in argument. We first give a concise articulation of the critical view of argument, and then probe into both the apparent similarities and deep discrepancies between the critical view of argument and Johnson’s views on the dialectical tier and manifest rationality. On that basis, we disprove the conjecture that the presence of a dialectical tier indicates that the thesis in argument (...) is critically established. However, we also urge to bridge together the critical view of argument and Johnson’s theory of argument, and thereby to make the dialectical tier critical in nature. We argue that this could be a promising proposal, and conclude with some remarks on exploring the critical dimension within our current study of argument. (shrink)

In this article I address the following question: When are reformulations in argumentative criticisms reasonable and when do they become fallacious straw men? Following ideas developed in the integrated version of pragma-dialectics, I approach argumentation as an element of agonistic exchanges permeated by arguers’ strategic manoeuvring aimed at effectively defeating the opponent with reasonable means. I propose two basic context-sensitive criteria for deciding on the reasonableness of reformulations: precision of the rules for interpretation (precise vs. loose) and general expectation of (...) cooperativeness (critical vs. constructive). On the basis of analysis of examples taken from online political discussions, I argue that in some contexts, especially those that are critical and loose, what might easily be classified as a straw man following conventional treatment should be taken as a harsh, yet reasonable, strategic argumentative criticism.

In this paper I shall examine Ralph Johnson’s concept of argumentation practice. He provides the following three desiderata for a critical practice: It is teleological, it is dialectical, and it is manifestly rational. I shall argue that Johnson’s preferred definition of practice – which is MacIntyre’s concept of practice as human activity with internal goods accessible through participation in that same activity – does not satisfy his desiderata.

A critical examination of the dialectical approach, focusing on a comparison ofthe illative and the dialectical definitions of argument. I distinguish a moderate, a strong and a hyper dialectical conception of argument. I critique Goldman's argument for the moderate conception and Johnson's argument for the strong conception, and argue that the moderate conception is correct.

Many standard definitions of ‘argument’ that recognise an ambiguity between its active and objective senses seek to subsume these in various ways into a single, composite whole. This, it is argued, glosses over the distinction instead of exploiting its elucidatory potential. Whilst optimistic about the prospects of theory integration, the paper recommends a methodology of differentiation as a first necessary step towards any such goal. It starts by assuming that ‘argument’ refers —simultaneously and independently— to two different things, making space (...) between them for a theory of argument based on the then necessary externality of the relation between them.

Ralph Johnson argues that mathematical proofs lack a dialectical tier, and thereby do not qualify as arguments. This paper argues that, despite this disavowal, Johnson’s account provides a compelling model of mathematical proof. The illative core of mathematical arguments is held to strict standards of rigour. However, compliance with these standards is itself a matter of argument, and susceptible to challenge. Hence much actual mathematical practice takes place in the dialectical tier.
