In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 36.3 (2003) 223-248 [Access article in PDF] Probabilities, Signs, Necessary Signs, Idia, and Topoi:The Confusing Discussion of Materials for Enthymemes in the Rhetoric Brad McAdon This essay examines three groups of "sources" or "materials" of enthymemes in Aristotle's Rhetoric. According to the text of the Rhetoric, enthymemes are derived from, among other things, probabilities, signs, and necessary signs, and/or from the topics, and/or from idia as (...) the following table indicates.1The Rhetoric does not explain any relationships that may exist between these different sources (or materials) from which enthymemes are said. This problem, as I am framing it, is two-fold: First, these different conceptions of materials from which enthymemes are said are never reconciled into a coherent account (or theory) in the Rhetoric. Rather, each conception of materials for the enthymeme is presented in a way that obscures, rather than facilitates, our understanding of the materials of enthymemes in the Rhetoric. Moreover, when Rhetoric 2.22-23 and its textual contexts are compared to 1.2 and its textual contexts, several differences will emerge [End Page 223] in respect to the nature of the materials of enthymemes and the distinctions in enthymemes that further cloud our understanding of the text. Second, many contemporary commentators place more emphasis on the dialectical aspects of rhetoric than the demonstrative. For while rhetoric is said to be closely related to dialectic in important ways in the early portions of the Rhetoric (especially 1.1-2), there are, arguably, more similarities between the materials of enthymemes in the Prior and Posterior Analytics (and thus demonstrative argument) than in the Topics (and dialectical argument). This suggests that the discussion of the materials of enthymemes in the Rhetoric is more demonstrative in nature (or at least in emphasis) than dialectical, and I hope to demonstrate that this is the case.As far as I can tell, Grimaldi's discussions of the "Eikota and semeia" (1972, 104-15) and "The topoi" (115-35) are the only contemporary attempts to explicitly address the relationship between probabilities and signs and the topoi in the Rhetoric. 2 Grimaldi's account is confusing in many respects. For example, in addition to understanding the idia as topoi, he claims that "[w]hen Aristotle has presented us with the sources of the enthymeme, eikota and semeia, and told us that they are the premises of enthymematic reasoning (A3, 59a7-10) the question which immediately arises is where does the rhetor turn for the material which will provide him with such eikota and semeia. The answer is: the topics" (115). Yet, a little further down the same page, he claims that "the topics are sources, or loci, both particular and general, to which one must have recourse in constructing probable argumentation by enthymeme in an effort to effect pistis" (115). So, in effect, Grimaldi claims that probabilities and signs are the sources of enthymemes and then that the topics are the sources of probabilities and signs, 3 but, as demonstrated above, the text of the Rhetoric clearly claims that the topoi are the sources of enthymemes just as probabilities, signs, and necessary signs are sources of enthymemes. Grimaldi fails to address or even acknowledge this. Rather, in his attempt to maintain the unity of the text of the Rhetoric, he has advanced this working relationship between eikota and se-meiaand the topoi in what he claims is a consistent theory in the Rhetoric concerning the relationship of eikota and se-meia (and tekme-ria)to the topoi that, I will argue, is not supported by the text as Grimaldi suggests. More recently, Robin Smith (1989 and 1997) provides carefully informed commentary on some of these terms—topos, idia, eikos, se-meia, and tekme-ria—but, and this is not his purpose, he does not provide a discussion that explicitly examines how (or if) these different terms relate to one another as sources of enthymemes. Thus, this essay is an attempt to explore and succinctly articulate the problems with the... (shrink)
