The purpose of this paper is to inquire whether the paradigma-approach, developed by Thomas S. Kuhn, is able to serve as a useful instrument for the analysis of the dynamics of economic theory. The first part contains a discussion of the rational reconstruction of Kuhns idea, which was formulated by Sneed and Stegmüller. This discussion centers around the question, whether rationality alone can be the only criterion for scientific work. In order to introduce the specific conditions under which economic science (...) takes place, the paradigma-approach has to be extended. This extension has to take account of the non-scientific determination of scientific work. In this connection normal science and scientific revolutions have a concrete function in a process in the course of which non-scientific claims are transformed into scientific norms. (shrink)
