 In any case, a critical question is: can some false-but-rigorously-empirically-successful theories justifiably be deemed truthlike from the point of view of successor theories? This question is hard to answer without looking at actual cases in the history of science. The general point, made by Vickers (2017) is that it is not enough for the challenger of realism to identify some components of past theories which were contributing to their successes such that they were not retained in subsequent theories. The challenger of realism should show that false components “merit realist commitment”. If they do not, “ (…) that is enough to answer the historical challenge”.
