Abstract

Toulmin’s original models of argumentation and human reasoning are reexamined in this paper from the perspective of evolutionary and cognitive theory. On the basis of recent work done from the biological and adaptationist perspectives in communication studies, it is to be demonstrated how neo-Darwinian and cognitive psychology may provide the platform for an understanding of the relationship of argumentation to human reasoning and communicative faculties. The Toulmin’s notions of field dependence and independence in argument are then reexamined and reappraised in light of this approach.
