According to selective, retentive, scientific realism, past empirical success may be explained only by the parts of past theories that are responsible of their successful predictions being approximately true, and thus theoretically retained, or approximated, by the parts of posterior theories responsible of the same successful predictions. In this article, we present as case study the transit from Ptolemy’s to Kepler’s astronomy, and their successful predictions for Mars’ orbit. We present an account of Ptolemy’s successful prediction of Mars’ orbit from (...) Kepler’s perspective, and scrutinize whether the theoretical elements responsible for Ptolemy’s empirical success are approximately retained in Kepler. In order to give to the realist the best chances, we try different strategies. We conclude that all fail and thereby this case constitutes a prima facie strong anomaly for selective retentive realism. Structural realists may call preservation of structure to the rescue, but the existing notions of structure do not work. In absence of a new notion that works, the burden of the proof lies on the realist side. (shrink)

Ptolemy´s astronomy and the Galileo case: two historical and epistemological considerations The Galileo case is the most famous example of the encounter betwen science and Faith. The debate was centered, among others, in the field of epistemology and the history of science. The paper shows that the Galilean pretentions of interpreting the heliocentric hypothesis in a realistic way did not constituted a novelty, but rather it was a continuation of the most important Ptolemaic astronomical tradition. It also argues that the (...) Copernican hypothesis did not inaugurate, because of the introduction of the Earth´s motion, a new phase of conflict between astronomy and physics. This conflict already existed, at least, since the times of Ptolemy. (shrink)

Science-engaged theology has emerged as a new way of conducting research within the vast field of science and religion, with the aim of, at least in one way of understanding it today, solving theological puzzles. In this article we suggest that an analysis of the diversity of approaches in which thirteenth-century philosopher and theologian Thomas Aquinas engaged theological questions with the best knowledge of the natural world available at the time allows twenty-first century science-engaged theologians to move forward the discussion (...) about the different ways of engaging theology with the contemporary natural sciences.
