Empirismo, Estructuralismo y Cambio Científico

Abstract

In the last decades there was a structural turn in the classic debate between scientific realists and antirealists with empiricist orientation. Two main arguments support the realist conception: the ‘No Miracle Argument’ and the thesis of continuity. The thesis of continuity states that some parts of a theory are retained when a scientific change takes place. In a current famous article, J. Worrall (1989) defends the continuity argument by stating that what is preserved in the succession of two empirically successful theories are the relations among the postulated entities and not the nature of the

relata (structural or syntactical realism). Based on this perspective, van Fraassen introduces his position named Empiricist Structuralism, which claims that only the structures of phenomena are retained. This conception tries to explain the success of science and at the same time defend the continuity of structures. I will demonstrate in this paper that the accomplishment of the two mentioned requirements imply a capitulation in favor of realistic intuitions.
