There Are No Such Things As Theories

There Are No Such Things as Theories considers the fundamental question: what is a scientific theory? It presents a range of options - from theories are sets of propositions, to theories are families of models, abstract artefacts, or fictions - and highlights the various problems they all face. In so doing it draws multiple comparisons between theories and artworks: on the one hand, theories are like certain kinds of paintings with regard to their representational capacity; on the other, they are like musical works in that they can be multiply presented. An alternative answer to the question is then offered, drawing on the metaphysics of musical works: there are no such things as theories. Nevertheless, we can still talk about them, since that talk is made true by the various practices that scientists engage in. The implications of this form of eliminativism for the realism debate is then discussed and it is concluded that this may offer a more flexible framework in which we can understand both the history and the philosophy of science in general.
