Abstract

The study of controversies is not only helpful for the further understanding of the subtleties of the theories involved, but it also contributes to the clarification of a series of issues related to the problem of theory choice. Discussions and disagreements — however heated — over two theories do not necessarily entail the features of what I would like to consider as controversies. This is especially so when there is a crucial experiment that can be performed in a relatively short period. Controversies are disputes over theoretical issues, methodological questions, and not infrequently, philosophical positions. It is in this respect that controversies are also a quite suggestive probe into the conceptual framework of the various researches.
