Ralph Johnson's Manifest Rationality (2000) is a major contribution to the field of informal logic, but the concept of argument that is central to its project suffers from a tension between the components that comprise it. This paper explores and addresses that tension by examining the implications of each of five aspects of the definition of ‘argument’.

The paper presents a historical overview of some characteristic differences between rhetoric and dialectic in the pre-modern tradition. In the light of this historical analysis, some current approaches to dialectic are characterized, with special attention to Ralph Johnson's concept of dialectical tier.

I propose some changes to the conceptions of argument and of argumentative discussion in Ralph Johnson's Manifest Rationality (2000). An argument is a discourse whose author seeks to persuade an audience to accept a thesis by producing reasons in support of it and discharging his dialectical obligations. An argumentative discussion (what Johnson calls ‘argumentation’) is a sociocultural activity of constructing, presenting, interpreting, criticizing, and revising arguments for the purpose of reaching a shared rationally supported position on some issue. Johnson's theory (...) of argumentative discussion, with occasional modifications, is derived from this definition as a sequence of 17 theorems. Argumentative discussion is a valuable cultural practice; it is the most secure route to correct views and wise policies. (shrink)

This paper responds to two aspects of Ralph Johnson's Manifest Rationality (2000). The first is his critique of deductivism. The second is his failure to make room for some species of argument (e.g., visual and kisceral arguments) proposed by recent commentators. In the first case, Johnson holds that argumentation theorists have adopted a notion of argument which is too narrow. In the second, that they have adopted one which is too broad. I discuss the case Johnson makes for both claims, (...) and possible objections to his analysis. (shrink)

He further argues that it is necessary to rethink traditional conceptions of argument, and to find a position that avoids the limitations of both the highly abstract approach of formal logic and the highly contextualized approaches of rhetoric and communication theory.".

Unlike most texts in critical thinking, _Reason in the Balance_ focuses broadly on the practice of critical inquiry, the process of carefully examining an issue in order to come to a reasoned judgment.

One of the traditional ways in which we manage dissensus is by argumentation, which may be construed as the attempt of the proponent to persuade rationally the other party of the truth of some thesis. To achieve this, the arguer will often anticipate a possible objection. In this paper, I attempt to shed light on the normative aspect of the task of anticipating objections. I deal with such questions as: How is the arguer to anticipate objections? Which of the anticipated (...) objections are to be dealt with? What is required to deal successfully with an objection?

We argue that the central goal of critical thinking is the making of reasoned judgments. Arriving at reasoned judgments in most cases is a dialectical process involving the comparative weighing of a variety of contending positions and arguments. Recognizing this dialectical dimension means that critical thinking pedagogy should focus on the kind of comparative evaluation which we make in actual contexts of disagreement and debate.
