The following collection of articles does not attempt to offer a global overview of the topics which are the subject of attention for philosophical study of science carried out in Spain. Rather, the collection represents just one selection of questions for which the authors either Spanish or closely linked to Spanish universities offer their own contributions in order to further the better knowledge of the areas of study dealt with. Thus no claim is made to be offering an exhaustive selection; in fact, the possible exclusion of topics of greater interest is not discounted either. It cannot be denied that any selection depends on the personal background and inclinations of the editors. In this sense, the present volume attempts to serve also as an invitation for developing new projects in connection with the perspectives, problems and topics of philosophical investigation developed within the Iberian Peninsula.
