Perelman's work has been very influential in various disciplines, among them philosophy, rhetoric and law. Especially the typology of argumentative schemes which he developed together with L. Olbrechts-Tyteca has been considered as an excellent classification of arguments in natural language. There are, however, some weaknesses of this typology which make its application to empirical research quite difficult, namely, the lack of explicitness and the absence of clear criteria of demarcation. Still, the typology is highly relevant for empirical research, if these (...) weaknesses are removed. This is illustrated with an example: the scheme called ‘the division of the whole into its parts’ by Perelman/Olbrechts-Tyteca is described explicitly and then applied to the analysis of a sample of everyday arguments (mostly taken from newspapers).

The author compares two theoretical models which develop constructs of an ideal audience. Chaim Perelman's universal audience serves a methodological function within the New Rhetoric which provides for the examination of philosophical arguments on values. Implicit within the work of Isocrates is a competing image which asserts that the ideal audience is empowered by the conditions of argument to engage the advocate in discursive praxis to construct and embody a consensus on contingency-driven value debates. The author concludes that the concept (...) of an ideal audience will be most valuable where interest in adherence to theses is less central than attendance to relationships born in and borne by discourse. Such a view has purchase within a constitutive view of rhetorical relations which asserts that the most useful role for argument is as an invitation to engagement. The situation of argumentation within a deontological ethics requires the partnership and participation of individuals in a mutually constructed discursive praxis. (shrink)
