ABSTRACT
Analytic, dialectic, and rhetoric, as developed in antiquity, still provide an important background to contemporary studies of argumentation. Having discussed some of the major concepts in chapter 2, and prior to our discussion of the present state of argumentation theory, we now turn to some historical contributions of a much more recent date. In this endeavor, we shall pay attention to the study of fallacies, the theoretical contributions of Crawshay-Williams and Naess, and the still influential argumentation theories of Perelman and Olbrechts-Tyteca, and Toulmin.
