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)

I propose a characterization of the dialectical dimension of argumentation by considering the activity of arguing as involving a “second order intersubjectivity”. I argue that argumentative communication enables this kind of intersubjectivity as a matter of the recursive nature of acts of arguing—both as justificatory and as persuasive devices. Calling attention to this feature is a way to underline that argumentative discourses represent the explicit part of a dynamic activity, “a mechanism of rational validation”, as Rescher showed, which is a (...) practice that presupposes the possibility of attaining objectivity.

Why is there so much misrepresentation of arguments in public forums? Standard explanations, such as self-interested biases, are insufficient. An additional part of the explanation is our commitment to, or belief in, norms that disallow responses that amount to no firm judgment, as contrasted with definite agreement or disagreement. In disallowing no-firm-judgment responses, these norms deny not only degrees of support or dissent and a variety of ways of suspending judgment, but also indifference. Since these norms leave us with only (...) constricted options that are very intellectually demanding, in accepting these norms we impose on ourselves a pressure to justify our judgment that lends itself to relief through misrepresentation or distortion.

Why is there so much distortion in ordinary, political, social, and ethical argument? Since we have a pervasive interest in reasoning well and corresponding abilities, the extent of distortion invites explanation. The leading candidates are the need to economize, widespread, fallacious heuristics or assumptions, and self-defensive biases. I argue that these are not sufficient. An additional force is the intellectual pressure generated by acceptance of norms of conversation and argument, which exclude ‘middles’ of, prominently, neither accept nor reject. I conjecture (...) that the distortion we find is due to intellectual and normative pressures generated by our commitment to these excluded-middle norms and if, or when, their force is lessened, there is likely to be less distortion.
