On this episode of ID the Future, biophysicist and philosopher Kirk Durston continue their discussion of three types of science--(1) experimental science, (2) inferential science, and (3) fantasy science. In this second of three episodes, Durston recaps the three types but focuses on inferential science. He explains how it involves, in the historical sciences, abductive reasoning (inference to the best explanation), and he explains how such reasoning can be used as we consider the best explanation for the origin of biological information, and in such a way that it is rooted in observation.
