Abstract

Besides systematic philosophical arguments, there are various extra‐scientific reasons that have been presented for or against realism. This discussion about the relations of knowledge and happiness started already among the ancient philosophers, and has continued ever since. Such religious, moral, and political considerations do not directly speak in favour or against the truth of scientific realism, but they raise important issues about science policy that have recently been topical in the so‐called Science Wars. Against Rorty's postmodern pragmatism and Feyerabend's epistemological anarchism, it is argued that critical scientific realism, with its commitment to the ethos of science as described by Merton's ethical norms, is in many ways a desirable philosophical outlook in a free, democratic, liberal society.
