Idealization, Confirmation, and Scientific Realism

The paper first raises the problem concerning the confirmation of idealized theories in science and its relationship to scientific realism. Then a solution by Laymon is discussed. It is then argued that two different types of idealization need to be distinguished and that only one of them produces false theories. But then, such “theories” are really theory-maps, which point to theories at the end of improvements. Finally, Laymon’s account is modified in accordance with the above insight.
