First, I identify a methodological thesis associated with scientific realism. This has different variants, but each concerns the reliability of scientific methods in connection with acquiring, or approaching, truth or approximate truth. Second, I show how this thesis bears on what scientists should do when considering new theories that significantly contradict older theories. Third, I explore how vulnerable scientific realism is to a reductio ad absurdum as a result. Finally, I consider which variants of the methodological thesis are the most (...) defensible in light of the earlier findings. (shrink)

The debate over scientific realism, simply put, is a debate over what we can and should believe about reality once we've critically assessed all the available arguments and empirical evidence. Thinking earnestly about the merits of scientific realism as a philosophical thesis requires navigating contentious historiographical issues, being familiar with the technical details of various scientific theories, and addressing disparate philosophical problems spanning aesthetics, metaphysics, epistemology, and beyond. This issue of Spontaneous Generations: A Journal for the History and Philosophy of (...) Science aims to make participating in the scientific realism debate easier for both newcomers and veterans, collecting over twenty invited and peer-reviewed papers under the title "The Future of the Scientific Realism Debate: Contemporary Issues Concerning Scientific Realism.".

It has become apparent that the debate between scientific realists and constructive empiricists has come to a stalemate. Neither view can reasonably claim to be the most rational philosophy of science, exclusively capable of making sense of all scientific activities. On one prominent analysis of the situation, whether we accept a realist or an anti-realist account of science actually seems to depend on which values we antecedently accept, rather than our commitment to “rationality” per se. Accordingly, several philosophers have attempted (...) to argue in favour of scientific realism or constructive empiricism by showing that one set of values is exclusively best, for anyone and everyone, and that the downstream choice of the philosophy of science which best serves those values is therefore best, for anyone and everyone. These efforts, however, seem to have failed. In response, I suggest that philosophers of science should suspend the effort to determine which philosophy of science is best for everyone, and instead begin investigating which philosophy of science is best for specific people, with specific values, in specific contexts. I illustrate how this might be done by briefly sketching a single case study from the history of science, which seems to show that different philosophies of science are better at motivating different forms of scientific practice.

This paper contributes to the debate on the question of whether a systematic connection obtains between one’s commitment to realism or antirealism and one’s attitude towards the possibility of radical theoretical novelty, namely, theory change affecting our best, most successful theories (see, e.g., Stanford in Synthese 196:3915–3932, 2019; Dellsén in Stud Hist Philos Sci 76:30–38, 2019). We argue that it is not allegiance to realism or antirealism as such that primarily dictates one’s response to the possibility of radical theoretical novelty: (...) what matters the most is, rather, the proposed alternative’s promise to realize one’s favored cognitive aim(s). Our argument tells not only against Stanford’s account of how adherence to realism or antirealism orients how one responds to possible radical theoretical novelty, but also against what we call the “natural pairing thesis.” According to such a thesis, which has kept resurfacing in the history of the philosophy of science, one-to-one pairings obtain between realism/antirealism, on the one hand, and theoretical conservatism/openness to radical theoretical novelty, on the other hand. As our argument suggests, however, when faced with the possibility of radical theoretical novelty, realists can respond either in a conservative way or by being open to theory change, not unlike antirealists.
