SERNA RAMIREZ, Edgar. Duhem’s thesis, Feyerabend’s methodological anarchism and the question about the justification of epistemic change. Rev. humanid. Valpso. [online]. 2021, n.18, pp.173-192.  Epub Dec 01, 2021. ISSN 0719-4234.

Duhem-Quine's thesis provides plausibility for Feyerabend's methodological anarchism by showing that the empirical refutation of a theoretical system is as chimerical as its verification. Grünbaum argues against this that such a thesis is untenable. They both agree in the formulation of Duhem's argument as it was exposed by Quine. However, the exegesis carried out by Quinn, Laudan and Ariew makes it clear that it is a mistake to identify the Duhem-Quine thesis with the Duhem thesis. I argue that, if this is so, then a refutation that can be accepted as such only in retrospect is logically possible.

Keywords : Objectivity; arbitrariness; rationality; criticism; persuasion; theory choice.
