 The plurality of scientific methods and practices is socially organized through a plurality of disciplines and institutions. Relationships between disciplines may take various forms (multidisciplinarity, pluridisciplinarity, interdisciplinarity, transdisciplinarity), depending on the nature of the connections and the retained degree of autonomy, and have been extensively studied in history and social studies of science. On the philosophical side, key issues are the benefits of disciplinary integration as well as epistemic, ontological, and social tensions of such integration processes.
