Abstract

In this paper I am developing the theses that argumentation is a means for extending knowledge. The theses are founded on two focal points:1. Reasoning is designed for argumentation, and 2. Argumentation process is an exceptionally successful media that provokes usage of methods reliable for the extension of knowledge. The first point relies on Sperber’s and Mercier’s evolutionary psychological approach to argumentation which I consider the most convincing theory in the field. Taking this ground as a departing point, the goal of the paper is to broaden this approach with epistemological insights that I base on Williamson’s safety theory of knowledge.
