Miracles and Models: Why reports of the death of Structural Realism may be exaggerated: John Worrall

What is it reasonable to believe about our most successful scientific theories such as the general theory of relativity or quantum mechanics? That they are true, or at any rate approximately true? Or only that they successfully ‘save the phenomena’, by being ‘empirically adequate’? In earlier work I explored the attractions of a view called Structural Scientific Realism. This holds that it is reasonable to believe that our successful theories are structurally correct. In the first part of this paper I shall explain in some detail what this thesis means and outline the reasons why it seems attractive. The second section outlines a number of criticisms that have none the less been brought against SSR in the recent literature; and the third and final section argues that, despite the fact that these criticisms might seem initially deeply troubling, the position remains viable.
