Hoyningen-Huene, Paul (13. September 2011): The Ultimate Argument Against Convergent Realism and Structural Realism: The Impasse Objection. XXII. Deutscher Kongress für Philosophie, 11. - 15. September 2011, Ludwig-Maximilians-Universität München.


For the sake of argument, two assumptions are conceded to convergent realism. First, a theory space with a metric can be defined containing the relevant sequence of theories. Second, the convergence of this sequence can be diagnosed on the basis of a finite number of elements. The impasse objection states that the limit theory may be substantially different from the true theory. This objection also hits structural realists who base their realism on the stability of structure in the sequence.
