The article deals with problems of incommensurability and meaning change in thecontext of scientific dynamics. Its main topic is a proposal made by Putnam basedon his version of the principle of charity. It is shown that this proposal does not workas a general principle for the understanding of theory change, for it leads in some cases to an unconvincing interpretation of now discarded theories and is even uncharitable. So it could be polemically described as a kind of defamation ('üle Nachrede') (...) of these theories. This will be demonstrated in two case studies. The first one sketches the development of economic value theory, while the second deals with the development of the concept of probability. (shrink)

Most philosophers of economics are hostile towards neoclassical economics in general and general equilibrium theory in the vein of Arrow and Debreu in particular. Especially the latter’s dismissal is justified by pointing out its lack of direct relevance for an understanding of real economies. Many recommend a more pragmatic approach along the lines of Keynes instead. The criterion of scientific legitimacy underlying this approach derives from a philosophy of science developed along the lines of Popper and Lakatos. They, however, neglect (...) the importance of conceptual problems and of the choice of adequate ‘language-systems’ in science. Since these conceptual and ‘linguistic’ aspects may be able to explain and to justify the rationale of the Arrow-Debreu approach, I recommend the more balanced philosophies of Carnap and Laudan, in which conceptual as well as empirical problems are allowed for, as a framework for methodological appraisal. I explain why such a balanced view is obstructed for most philosophers of economics and advocate a moderate pluralism leaving room for different theories, methodologies and language-systems, depending on the scientific aims that are pursued.
