The historiographic tradition of the history of science that originated with Auguste Comte bears all the marks of narratives with roots in the Enlightenment, such as a view of religion as an underdeveloped stage in the ascending road in humanity's quest for a more mature understanding. This article explores the development of the peripheral branch of a tradition that developed in Argentina by the mid‐twentieth century with authors such as the Italians Aldo Mieli, José Babini, and the Hungarian Desiderius Papp. (...) It is argued that, contrary to the historiographic program of the conflict thesis developed in English‐speaking countries, those scholars who cultivated the kind of “positivist” history of science that thrived in continental Europe were inclined to see science as a social and epistemological replacement of a fossilized religious outlook. In the final section, I suggest a way to relate the more or less strong versions of the conflict thesis to different patterns of secularization. (shrink)
