According to Aristotle, theory is the highest, rational form of knowledge. But do we need theories at all, given the new possibilities created by artificial intelligence to machine process vast amounts of data? The book is based on a two-day symposium jointly organized by the Robert K. Merton Center for Science Studies and the Gesellschaft für Wissenschaftsforschung Berlin. The symposium focused on three themes: 1) Theorizing and its new media: What kind of theorizing do science podcasts enable? 2) Epistemology and (...) the metaphysics of theory, with some remarks on the philosophy of science, including the role of theory in university teaching; 3) AI and theory, with the final question of theory and the transparency of knowledge organization. The book begins with a reflection by Andrew Abbott on theory in the social sciences. (shrink)
