The importance of limitations to scientific underdetermination in the context of string theory raises the question in how far that notion has been underrated in general philosophy of science. Arguments to this end may be led at two levels. On the one hand, it seems possible to identify implicit assumptions of limitations to scientific underdetermination at various stages of the history of physics. Examples are the treatment of scientific objects throughout the twentieth century or the at times very strong belief in the existence of unobserved elementary particles due to consistency arguments. At a more general level, limitations to underdetermination may be utilized in fundamental conceptual debates of philosophy of science. In particular, they could play an important role in the context of the no miracles argument for scientific realism. The latter infers a realist interpretation of scientific objects from the observed predictive success of scientific theories. Serious conceptual problems of the no miracles argument could be avoided by replacing the inference to scientific realism with an inference to limitations to underdetermination. (see [3].)
