Three Objections to the Epistemic Theory of Argument Rebutted

EPISTEMIC THEORIES OF ARGUMENT: AN OVERVIEW The epistemic theory of argument is the view that arguments are to be evaluated in terms of their comprising epistemic reasons. This is to say, good arguments are those that are conducive of or pursuant of knowledge. Epistemic theories of argument vary according to how knowledge and epistemic reasons are delineated--from, for example, the veritistic and social in Goldman's analysis (1999, 2003) to the evidentialist and individual in Feldman's (1994, 2005). What makes these widespread forms of a family is the central role that the concepts of knowledge and epistemic justification play in the analysis of what constitutes good arguments. What follows in this section is a rough map of the dialectical terrain around epistemic theories of argument. My overall objective is to provide defenses for epistemic theories of argument as a family from objections arising from the rhetorical tradition. The appeal of epistemic theories can be captured by the axiological and the constitutive norm arguments. The axiological argument is that since arguments are to be normatively evaluated, a theory of argument must provide criteria for those evaluations. Epistemic theories provide normative criteria for good arguments and may be deployed to explain why fallacies are fallacious: they fail in some way or other to provide epistemic support. The alternatives, as the argument goes, fail to provide such explanations. Rhetorical theories provide criteria for evaluation (that of eliciting assent), but then cannot address the problem of fallacies (they convince, but shouldn't). This, again, is a rough challenge for the rhetorical theories of argument, one that stretches all the way back to Socrates' concerns about rhetoric in the Gorgias (465 a-d). Pragrna-dialectical strategies evaluate arguments on their procedural correctness in rationally reducing conflict, but they leave open the question of why the procedures should be rational and what the nature of that rationality is. On the axiological argument, epistemic theories are the last standing (cf. Biro & Siegel, 1992, 1997; Feldman, 1999; Freeman, 2006). The constitutive norm argument is that so long as arguments are supposed to achieve any change in view from audiences, as the competing theories hold, they must do so on (or on what passes for) good epistemic grounds. Listeners don't knowingly change their minds about things unless they think that adopting the new view puts them in a better cognitive position with regard to the truth of what is believed. Epistemic reasons provide that connection between belief and truth, so arguments, by their bearing on the truth of their conclusions, must be epistemically bounded (cf. Aikin 2006, 2008a; Cherwitz, 1977; Cherwitz & Darwin, 1995; Cherwitz & Hikins, 1986; Heysse, 1998; Scott, 1967, 1976; Stark, 2000; Zaner, 1968). This is to say that so long as one changes one's mind about a matter only under the conditions that one takes the new view as more likely true than its competitors, the reasons for this comparative judgment must bear on and be productive of knowledge of the truth of those theses. Those reasons are, by definition, epistemic reasons. As a consequence, epistemic theories are of a broader family with logical theories of argument--that one constitutive objective of arguments is arriving in a manner that confers the committed subject with a warrant for her conclusion. Epistemic theories assess the connection between premises and conclusions as argumentative products in a similar, but broader, fashion compared to logical theories. But these theories, again, broadly take arguments as the primary object of evaluation, and are posited on the assessment of the connection between reasons proposed or presumed and the conclusion according to general rules of good reasoning. There has been a measure of resistance to epistemic theories. A number of lines of argument have come out, and here I will respond to three I take as connected and widespread. …
