Idealization, Abduction, and Progressive Scientific Change

Xavier de Donato-Rodríguez


After a brief comparison of Aliseda's account with different approaches to abductive reasoning, I try to relate abduction, understood in terms like those of Aliseda, to another concept which also occupies a very important role in scientific change: idealization. In particular, I try to reveal some interesting aspects related to notions like approximation and empirical progress.
